Description

Technical field

The invention relates to the field of utilization and processing of solid municipal waste (MSW) with the subsequent production of building / finishing materials and building structures, where the “tails” are the filler in their manufacture — the residual fractions (RP) of the MSW after their 2-stage separation, followed by the addition magnesia binders, and can be widely used in public utilities, in industrial and civil engineering.

The level of technology.

The prior art method for processing a mixture of substances that can be used for processing MSW, rubber, plastic, ore to produce products - synthesis gas, metals, glass, etc. (RU 2356655 C2, B09B 3/00, publ. 27.05.2009). The method includes sorting substances by weight, drying, grinding, processing and sorting the waste, acting on them in various ways (chemical compositions, electric discharges and thermal shock), converting organic substances into products by pyrolysis into gas, carbon and liquid fuel, and obtaining products from inorganic substances. The disadvantage of the above Method is the high cost of energy.

The Method of waste processing is also known from the prior art (EP 2662145 A1, B03B 9/06, publ. 15,03,2013), in which MSW are delivered to a waste recycling complex, large-sized waste (CSW) is separately processed to secondary resources, MSW are sorted into suitable for further processing and use in the economy of secondary resources, the waste is dried and crushed. The disadvantage of the above Method is the inability to completely process the received MSW.

The prior art also discloses a Method for utilizing MSW (KZ 18441 A, B03B 7/00, published May 15, 2007), including extracting secondary resources from MSW, including iron-containing inclusions, successive stages of crushing and grinding, to which MSW is fed by flow moving with simultaneous drying, while dry powdered MSW are mixed in one mixer with liquid industrial waste with the subsequent production of pulp and gas, which is removed from the mixer into the cleaning system.

The disadvantage of the above Method is the complexity of the disposal of MSW, due to the subsequent chemicalization of waste.

The closest analogue to the considered method is the method of MSW processing with the production of thermal energy and building materials, and an incinerator for its implementation (RU 2502017 C1, F23G 5/00, published on December 20, 2013). This method involves the disposal of MSW by burning in a rotary kiln of a drum type, and the remaining ash is melted into granular slag, which can be used in road construction and the production of building materials. The incineration plant contains a MSW incinerator, a smoke cleaning system, a reactor for melting ash with a plasma torch, and a power source. The disadvantage of this technical solution is low productivity, expensive flue gas cleaning system, high energy consumption, low liquidity of the products obtained.

Disclosure of the invention.

The technical result of this invention is to increase the efficiency and environmental friendliness of MSW processing, reduce energy costs for MSW processing, the possibility of using residual MSW fractions after 2-stage separation, the so-called MSW “tailings”, in the production of building / finishing products and building structures, the practical absence any waste, increasing the self-sustainability of production by processing the entire amount received for disposal at the ZW Industrial Complex (abbreviated as "ZERO WASTE" , or “ZERO WASTE”) of MSW, including the receipt of part of the received MSW (up to 30%), usually carbon-containing, the receipt of own energy (thermal and electric) to meet the own needs of the ZW Industrial Complex through the use of its own energy module operating on principles of "cold pyrolysis" (RU 2659924, published on 07/04/2018).

The specified technical result is achieved due to the fact that the ZW Industrial Complex for non-waste processing of MSW with the subsequent production of building / finishing Products and building structures from “tails” processed by MSW using magnesia binders, contains:

Thermal energy in the drying compartment comes from the energy module.

The energy module is a complex for the disposal of solid carbon-containing waste that has passed the drying department;

- The industrial complex ZW also contains a grinding compartment, containing high-performance crushing and grinding equipment (shredders), grinding dried RP solid waste of various morphological composition to fractions up to 0.1 ... 6.0 mm in size;

- Pulpa preparation department, from where the finished Pulpa is fed through pipelines to the temporary pulp storage warehouse (SHHP), made in the form of vertical type tanks, usually steel, while the SHHP is connected by pipelines to the distribution and transportation center, from where Pulpa goes to construction production facilities / finishing Products and building structures and is used as a filler in a mixture with magnesia binders (MgO and MgCl2, as a hardener) by molding or extrusion, in particular m accordance with approved technological regulations and the technological cards for each product and the structure.

The method of waste-free recycling of MSW with the production of building / finishing products and building structures from the “tailings” of the solid household waste after their 2-stage separation using magnesia binders includes the following steps:

- receipt of MSW in the receiving department of the ZW Industrial Complex;

A brief description of the drawings.

The figure depicts the "Scheme of the ZW industrial complex for waste-free disposal of MSW and for the production of building materials and structures from the" tailings "processed MSW using magnesia binders."

The implementation of the invention.

The ZW industrial complex for waste-free recycling of MSW with the subsequent production of building materials and structures from the “tailings” of processed MSW using magnesia binders works as follows:

- the reception department (1) of the ZW Industrial Complex receives both reproduced MSW from settlements (megacities, cities, other settlements and settlements), as well as from existing or closed MSW landfills. After acceptance of MSW, before sending MSW to a 2-level separation, preliminary / subsequent selection of CSW is carried out, which are subsequently sent for cutting, disassembling and subsequent sorting into useful, marketable secondary materials.

KGO, which are subjected to subsequent disassembly and cutting, include, for example, such as:

- furniture and beds of all types;

- mattresses;

- household appliances (refrigerators, washing machines and dishwashers, vacuum cleaners, etc.);

- bathtubs made of cast iron and steel;

- plumbing earthenware products;

- audio and video equipment;

- computers, printers, faxes and other office equipment;

- car tires;

- recycled motor vehicles;

- other KGO (building materials after dismantling and dismantling of buildings and structures: parts of building structures and structures, window blocks, door and balcony blocks, parts of ceilings and floors, etc.).

The aforementioned KGOs are sent to workshops (No. 1A ... No. nA) for disassembly and cutting to obtain marketable secondary resources (ferrous and non-ferrous metals, plastic of 8 ... 15 types, electronic boards, crumb rubber, wood chips, ground fractions of sanitary ware, suitable for subsequent processing) concrete, brick, glass, etc.);

- in the deep separation department (2.2-1.2-2) of MSW, which, in essence, is a waste sorting complex, secondary materials are selected (without KGO, 2-2) to obtain secondary resources suitable for subsequent processing. Separation (separation) of MSW in the deep separation department is carried out both in a semi-automatic mode of operation (using manual labor) and in automatic mode, using ballistic and optical separators and infrared sensors (sensors).

- further, the solid waste MS, including the separated fine fractions (less than 10 ... 20 mm) of MSW, for example, soil, sand, gravel, cullet, food waste, etc., enter the drying department (3.3-1.3 -2). The whole process of drying of solid waste is carried out automatically, without the presence of human operators, namely, dry solid waste after deep separation on a closed sealed conveyor goes to the drying department (3), to rotary drying drums, where dry solid waste is intensively dried at a temperature of 160 ... 200 degrees Celsius with stirring during rotation up to 12 ... 14% humidity, with the removal of water vapor into the atmosphere through ventilation pipes.

In this case, the thermal energy in the drying compartment (3) comes from the energy module.

- The energy module (9) is a complex of cold pyrolysis utilization of solid carbon-containing wastes (for example, cardboard, paper, car tires, shoes with rubber / polyurethane / leather soles, rubber boots, plastics of all types, including film bags, except PVC) , wood waste, including decayed organic substances in MSW, especially when MSW is collected from landfills, in significant specific volumes, which have passed the drying department (3), with the generation of heat and electric energy and through the use obtained by "cold pyrolysis" fuel products, such as pyrolysis gas, liquid fuel fractions, pyrolytic carbon, in solid form;

- further, the remainder of the dry solid waste MSW (up to 70% of the initial mass of received MSW) is fed to the grinding unit (4.4-1.4-2). The grinding compartment (4) contains high-performance crushing and grinding (shredder) equipment, consisting of a number of crushers of various types and powerful industrial shredders (2- and / or 4-shaft), which effectively grind dried RP MSW of various morphological composition to fractions 0.1 ... 6.0 mm;

- from the grinding compartment (4), the dry solid wastes of solid waste are transferred to the secondary separation department (5.5-1.5-2), in which secondary separation is carried out into heavy and light fractions, namely:

- fractions of 0.1 ... 6.0 mm size coming from the Grinding compartment (4) fall onto a conveyor-vibrating table, during movement along which they, the fractions, intensively mix with each other and, as it were, jump, then the light fractions are blown away by powerful streams of hot air special containers, and heavy fractions remain on the conveyor-vibrating table, that is, there is a fairly effective additional separation;

- further, the heavy fractions of the solid waste are sent to a warehouse (10) of heavy (inert) fractions, and the light fractions of the solid waste are sent for further processing to the pulp preparation department (6).

The stored heavy fractions are one of the final market products of the ZW Industrial Complex for the disposal of MSW, while such heavy fractions as ferrous and non-ferrous metals (small crushed residues that could not be recovered earlier) and crushed glass can be sent for additional processing as secondary raw materials , and such heavy fractions as crushed sanitary ware, construction waste (sand, brick, concrete, construction soil, gravel, etc.), estimates from city streets and megacities) can serve as inert filler in the manufacture of both the above Products of building / finishing types and building structures with the addition of magnesia binders, and traditional reinforced concrete products of a wide range, especially when used in unreasonable products of building and finishing types, such as, for example, foundation blocks, wall blocks, blocks for interior partitions, ceiling and finishing plates, as well as when used as anti-icing backfill roads and sidewalks, etc .;

- Light fractions of municipal solid waste, consisting of dried and shredded food waste, cellulose (dried and shredded cardboard and paper), shredded plastic, including plastic bags, shredded and partially converted into plastic granules during intensive drying in drying drums at temperatures up to 160 ... 200 degrees Celsius, crushed cotton fabrics, synthetics, their mixtures, soft children's toys, fabric upholstery from upholstered furniture, sleeping mattresses, etc., are then sent to the Pulpa cooking department (6).

- there, in the Pulpa preparation department, the light fractions of the solid wastes of solid waste are transferred to the bunker-mixer, where they are thoroughly mixed with the preserving NaCl brine and water (H2O) added through the doser until a homogeneous mass is obtained, with a viscosity from 50 MPa * s to 250 MPa * s for the possibility of further transportation of Pulps, including through pipelines to the place of temporary storage;

- Pulpa temporary storage warehouse (SVHP) (7) is made in the form of several vertical-type tanks, into which Pulp is temporarily stored through pipelines;

From SHPP (7), the pulp is fed to the distribution and transportation center (8), from where the further distribution and transportation of the Pulp for further processing takes place:

- to objects of road construction (8-1);

- objects of industrial construction (8-2);

- objects of individual construction (8-3);

- to production workshops (Shop No. 1 ... No. n) for the manufacture of Building / Finishing Products using Pulp as a filler using magnesia binders MgO and MgCl2.

- Transportation of Pulps from the distribution and transportation center (8) to points of use can be carried out either mechanically through an unloading collector through pipelines, or in bulk in railway tanks, tank trucks or in closed containers (to prevent splashing during transportation) on any transport including passenger;

- Further, Pulp, received from the distribution and transportation center (8), is used as a filler in the production of building / finishing Products and building structures. The pulp is mixed in a 1: 1 ratio with magnesia binders MgCl2 (bischofite) and MgO (caustic magnesite / dolomite), until a homogeneous mass is obtained - press mass (PM).

Brief information on magnesia binders.

Magnesia binders include caustic magnesite (MgO) and caustic dolomite (MgO + CaCO3) - these are fine powders, the active part of which is magnesium oxide MgO. Caustic magnesite / dolomite shutters with bischofite MgCl2.

Magnesia binders (magnesite / dolomite) are obtained by moderate (up to 700-800 ° C) firing. In this case, magnesium carbonate dissociates with the formation of magnesium oxide MgO + CO2. Calcium carbonate CaCO2 (in dolomite) remains unchanged and is the ballast part of the binder. The calcined product is carefully ground to a finely divided state. Being closed with an aqueous solution of magnesium salts MgCl2, caustic magnesite / dolomite form a plastic mass having strong astringent properties, which as a result of hardening forms a high-strength elastic cement stone. In the case when magnesia binders are closed with a bischofite solution, hydration proceeds quickly with the formation of magnesium chloride oxide hydrate (3MgOxMgCl2x6H2O), which compacts the resulting material. The setting time of caustic magnesite / dolomite depends on the firing temperature and fineness of grinding and is usually within:

- beginning - not earlier than 20 minutes;

- end - no later than 6 hours.

Hardening begins intensively, and after a day the binder reaches a strength of 10-15 MPa, and after 28 days of air hardening strength; is 30-50 MPa. In hard mixtures, strength can reach 100 MPa.

It should be emphasized that when using magnesia binders, biomass of various morphological composition (paper, cardboard, wood, food waste, various agricultural waste, etc.) can be used as filler, while magnesia binders to the above biomass WILL BE ABSOLUTELY NEUTRAL !!!

Thus, in the manufacture of a wide range of structures and products of building / finishing types and building structures based on magnesian binders (caustic magnesite / dolomite, sealed with bischofite), it is possible to use traditional inert fillers (sand, crushed stone, etc.) as a filler as well as biomass fillers (sawdust, wood chips, food waste and other organic fractions), including PW MSW, the so-called “tailings” from MSW processing, which are currently ravlyaetsya:

- to MSW landfills (up to 97% both in Russia and in the world);

- for incineration (up to 2%), but this volume of burned "tails" each; the year in the world is rapidly decreasing due to the extremely dangerous environmental impact around waste incineration plants (MSZHZ) within a radius of 100 km or more from their plants, location !!!;

- to other MSW disposal systems (up to 1%), including exotic ones (composting methods, MSW biogasification methods, biodegradation methods using appropriate bacteria and worms, etc.);

A thoroughly mixed mixture of magnesia binders and fillers (Pulpa), called the press mass (PM), is activated approximately 0.5 ... 1.0 hour before participating in the technological processes for the manufacture of building / finishing products, building and road structures .

The technology for using a mixture of magnesia binders and pulps in the formation of products or structures, as a rule, is similar to the production of products and structures in factories of reinforced concrete products or on construction sites, namely:

- a mixture of magnesia binders and Pulpa is placed (poured) into the appropriate molds, where it is then carefully vibro-compacted or subjected to additional external pressing and / or additional heating (with steam or hot air streams), or extrusion;

- after the mixture of magnesia binders and Pulp, placed in various molds, takes the form of the specified Product after the corresponding technological curing, the Product is freed from the formwork (molds) and sent to the technological curing in the finished product warehouse, from where it is shipped to the customer or to retail chains.

The proposed ZW Industrial Complex and the method of waste-free disposal of MSW with the production of building / finishing products and / or building and road structures from recycled MSW using magnesia binders allow implementing a waste-free MSW disposal system, both from settlements, cities and megacities, and from existing or closed MSW landfills, with their complete elimination in a historically short time (not to be confused with the rehabilitation of MSW landfills, where landfills remain in place and continue "Live your life" 50 more ... 100 years or more), which allows, in principle, to give up graves TKO, as well as ultra-hazardous method of incineration.

Note *: the abbreviation ZW is abbreviated as "ZERO WASTE", or "ZERO WASTE".
