Urban waste recycling 100 -300Tpd

DETAIL OF THE MACHINERY AND PROCESSES OF A STANDARD MSW TRAFFIC PLANT
 1. Introduction
             1.1- Overview
             The whole plant of the treatment plant, are proposed as an autonomous and complete unit for the entire process of selection of recoverable products that make up the R.S.U. Of the urban collection of the area.
             In order to deal with the solid urban waste generated, we propose to carry out a simple and manual operation, generating a significant number of jobs in the area, or fully automated, according to the needs of the client, through the development of a recycling, composting and Recovery of solid urban waste.
             The trucks from the municipal collection transport the waste to the plant. The weighing scale is the first point of the plant, usually next to the control building, where the vehicles must be weighed to carry out a good control of the tons of entrance and exit of waste in the plant, as well as their identification and registry. After the weighing, the truck passes to the ship or reception beach, where the waste is discharged and the cargo is loaded by the loader onto the pre-treatment line.
             The next point of the installation is the pretreatment or selection line. The objectives of the implementation of equipment of this line, detailed below, are, on the one hand, to recover recoverable inert waste and, on the other hand, to eliminate to the greatest extent possible the improper elements that contaminate the organic matter to obtain an organic fraction with Appropriate composting for this process.
             In this selection process, the recovery of:
 - Glass in bottles and commercial containers.
 - Large bulky objects.
 - The organic fraction for agricultural fertilizer.
 - Cardboard paper wrappings and packaging.
 - The plastic film of the wrappings.
 - Plastic bottle containers.
 - Metal cans of beverage cans and ferric materials.
 - Other elements of interest.
             The rejection of the selection process will be carried out to a controlled landfill, for its inertization by means of covering of vegetal lands, on which the reforestation will be fomented again and its integration to the environment and landscape of the zone.
             The organic matter coming from the separation in the treatment vessel is composed by a vessel composter in a covered ship, after mixing the material with the vegetal fraction in order to structure the material and to balance the C / N ratio and thus to obtain a good process of Composting.
             After this process, a compost is produced which, with the refining system, will acquire sufficient quality to be used in agriculture as fertilizer.
             The refinement of the composted material is composed of a line of equipment that separates the material by size and density with the aim of obtaining a product with the least number of improper possible for commercialization. Much of the rejection of this line will be the Vegetable Fraction inserted in the beginning of the composting and that, can be reintroduced in the process minimizing the volume of new VF to the plant.

1.2- Composition
             The sizing has been done as standard for plants with capacities of 50, 100, 200 and 300 Tn of daily RSU. A sampling of the trash bag will be necessary to adjust the sizing to the real needs of each plant.
             The proposed plants are formed by:
             1. MSW pretreatment machinery.
             2. Organic fraction refining machinery.
             3. Mobile machinery.
            To complete the plant, the following buildings and areas are required (not included in this budget).
             1. Administration buildings and services.
 - Scale stand.
 - Management Office.
 - Staff changing rooms.
 - Workshop - warehouse.
             2. Buildings for processing facilities

 - Building of composting and maturation.
 - Building of refinement.
             3. Storage area of vegetable fraction.
             4. Compost storage area.
             5. Water service facilities.
             6. Energy installations.
             7. Laboratory.
             8. Vials and urbanization.
 2.- Description of Facilities and Equipment
             At the entrance of the plant is located access control to the facility, provided with a small building where the weighing and control of the trucks is carried out using a scale.
             The ship of the reception area of the trucks will be covered ship, preventing with the residues are in the open and do not impregnate of too much humidity in times of rains and to avoid that happens flights of materials lighter in this part of the installation . The ship can also be opened or closed according to smell problems by population close to the plant. If the vessel is closed, a system of air renewal of the ships and deodorization must be available with a subsequent biological treatment of the air for the reduction of odors. The dimensions of the receiving vessel must ensure sufficient capacity to store the waste for 2-3 days minimum
             The reception, pretreatment, sorting, composting, maturing and refining facilities are confined within a rectangular covered structure of prefabricated concrete elements, covered with 15 cm of concrete and HM-25 concrete, on Layer of 10 cm of concrete HM-20 on natural zahorra and a free height of 8 m. These facilities are not offered.
             The waste received is dosed to the Metal Conveyor Belt through a metal hopper by means of a loader, and driven to the Rubber Belt with the first workstations for the selection of bulky which comprises 2 workstations eliminating the improper bulky ones. These bulky ones are stored in containers (not budgeted) for their subsequent removal of the plant. The bulky ones move away to avoid hindering the subsequent classification in the triage booth, thus being able to guarantee more adequate working conditions and, therefore, high selection percentages.
             Prior to this voluminous removal, a previous removal on the beach of discharge of those extra voluminous elements such as pallets, trunks, branches and highly contaminating materials such as batteries, electronic equipment (TV, Computer, etc) must be carried out.

The remaining residues of the line then enter the Rotary Classifier Trromet, which by means of the continuous rotation movement and the angle of inclination that it has by its form of assembly, produces a flipping and sailing of the various components of the RSU, incorporating a System to open the garbage bags which results in a size separation of its fractions since it incorporates in its interior a mesh with holes of diameter 80 mm, thus achieving separation of the garbage in the two desired fractions:
 - Fraction less than 80 mm (mostly organic and fine).
 - Fraction greater than 80 mm (mostly rest of valorizable and rejection).
            The diameter of the mesh of the trómel guarantees that in the fraction smaller than 80 mm the organic matter is mainly concentrated, reason why this one is led by means of tape towards the area of composting, with a long, to be defined, depending on the Distance to the area of Composting. The conveyor belt from organic to composting is provided with a magnetic separator to recover the small metallic materials that accompany the organic fraction. The extracted metals fall into a small container (not budgeted) for subsequent pressing.
             The larger fraction of 80 mm of the trómel is collected by a Rubber Band that leads it to the Secondary Triage Cabin. In this cabin, the fraction> 80 mm is subjected to a manual sorting process, which is carried out in a triage cabin. Throughout the Triage Tape five stations have been arranged for the selection of plastics, paper and cardboard, incorporating a pincha-botellas.
             Each of these stations has two discharge ports for independent silos or containers, located in the lower part of the manual sorting booth. These silos have sufficient capacity to store classified materials at least for each work shift. In the case of glass, as well as other materials that are not required to be packed, they fall directly into a container. The by-products recovered from the Second Triage Booth are collected in the corresponding storage bins located at the bottom of the triage platform. These are pushed by a loader and sequentially, as desired and depending on the amount of product stored in each silo, to the Pressing Metal Belt, located at one end of the triage zone.
             The Continuous Press of proposed recoverable products improves the efficiency of the storage of these materials and their final transport. This equipment is designed for continuous packaging with automatic banding of the bullets for all the byproducts of paper, cardboard, plastics, etc.
             The pretreatment line continues with the mechanical selection of ferrous materials through an Electromagnet and a Foucoult Separator for non-ferrous metals, the products of each type are separated and discharged to two containers (not budgeted) to be sent to the Metal Press .
             The rejection at the end of the triage line is transported to a Static compactor compacting it in a Closed Box of 3 m3 for the deposit and transport to the landfill
             The bullets obtained from the total separation of recoverable products will be removed from the press area by forklift truck (not offered) to be located in an area adjacent to the pre-treatment vessel called ship or beach of recovered products pending withdrawal of the plant.

             3.2- Metal Band Feeder
             Powered by a shovel from the beach of discharge, installed its initial part in a moat of 4 m. Long 1.5 m wide and 1 m. Of depth, consists of:
             3.3.- Structure of Triage for Voluminous
             Collect the material from the Feeder and transport it to the Trómel. Taking advantage of this transport is realized a Triage of bulky, placing the same in the two Boxes, which consists of:
             3.4- Trial Trial
             Receive the material from the Bulk Triage Tape and separate the larger materials from the smaller ones that will be destined for Composting.
             This tróel consists of a cylinder with meshes to three levels and of different caliber to be able to separate the organic fraction of the rest of fractions, also incorporates a pinchos to act like opens bags.
             3.5.- Rubber Conveyor Belts
             Smooth and oil-resistant 4-ply flat rubber bands will be located throughout the plant, forming the joining areas between the various equipment. They can also be installed to join the selection zone and the packaging areas, each recoverable material and the waste fraction, as well as in the organic line.
             3.6.- Triage Structure with 4 Boxes and Conveyor Belt
             Habitáculo where there are located between 8 and 10 workstations to make the definitive selection of all recoverable materials and rejection.
             3.7.- Pinch of bottles
             Placed in a hopper of the triage to puncture the bottles before falling into the box and being able to be compressed in the corresponding press.
             3.8.- Magnetic Separator
            Magnetic separator in charge of removing all ferrous elements remaining on the tape after the primary triage. It will be placed in both the organic and inorganic lines.
            3.9.- Foucault Current Separator
            The Foucault Non-Ferrous Metal Separator placed at the end of the triage booth will be in charge of removing all the aluminum, brass components, ie those non-ferrous materials.
            3.10.- Optical Separator
            The optical separator is responsible for the automatic classification of the following components of the MSW: 1 mm fine grading, with high accuracy, Classified of dry bulk materials with a particle size of 2-30 mm, Classification of glass, PET, minerals, sea salt And colored ro3.11.- Continuous Press for Paper, Cardboard and Plastics
            It is in charge of packaging the salvageable waste for storage and subsequent transfer.
            3.12.- Scrap Press
            It is in charge of packing the ferrous and non-ferrous materials for storage and subsequent transfer.
            3.13.- Organic Waste Crusher
            The crusher is installed at the end of the organic tape that comes from the tróel, and has as a function to reduce the size of the organic waste for a correct composting process.
            3.14.- Industrial Compounder Volcomp
            The system consists of a rotating steel drum. The waste entrance is produced through a tape that feeds it from the crusher. In the part of the glass, welded to its walls, there are sheets of steel together with blades that help to remove the materials and to crumble them. Inside it mixes the materials and keeps all the variables that affect the decomposition, temperature, humidity, aeration and mechanical mixing of all the materials in order to accelerate the composting process, obtaining the final immature product in approximately 5 to 7 days.
            The composting vessel requires less space than the traditional composting system outdoors using batteries. Bad odors, the appearance of leachate (liquid from organic matter decomposition), rodent and insect infestation and prevent changes in climatology affect the composting process, reduce the fire hazard and accelerate the Compost production.
            3.15.- Trómel de Afino
            The refinement of the composite material is composed by the meshed tróel that separate the material by sizes and densidades with the objective of obtaining a product with the least number of improper possible for its commercialization. Much of the rejection of this line will be the Vegetable Fraction that can be reintroduced at the beginning of the composting process.
            3.16.- Weighing Scales
            These scales will be installed at the end of the packaging line for weighing each of the bullets.
            3.17.- Static Compactor
