Description

The present invention relates to a process and apparatus for the treatment of high plastic solid K. municipal waste.

In particular, the method and apparatus of the present invention is directed to treating the inert fraction of solid municipal waste (heavy fraction such as building debris, glass, metal) and organic waste that is obtained after removal of contaminated, mainly plastic waste.

It is known that in the developed countries, the increase in household consumption worldwide is accompanied by a steady increase in solid municipal waste.

A. The collection and disposal of solid municipal waste therefore places an increasing burden on public clean-up bodies, generating 300-450 kg / person / year of household waste in Hungary, which is currently mostly dumped for a week Most of the landfills in Hungary do not comply with environmental regulations. are. As a result, the capacity of existing landfills is in the process of being drained, and that is why landfill costs have increased dramatically. High investment and operating costs both encourage operators to make system changes that reduce landfill and thereby extend waste disposal. the lifetime of the already installed: landfill capacity,

These are the fundamental problems of landfill as a waste management solution

1, Slowly decomposing litter in landfills releases environmentally harmful gases including odorous compounds (eg hydrogen sulphide) or greenhouse gases (eg methane, carbon dioxide),

2. Water escaping from the landfill causes environmental pollution and consequent damage when it enters groundwater and surface water. Therefore, by setting up landfills, <

Compliance with the relevant regulations can be achieved by thoroughly lowering the bottom plane of the landfill (to prevent the leakage of contaminated leachate into groundwater), evacuating the resulting gases and maintaining a continuous monitoring system, but at a considerable cost.

3. Recultivation and after-care have been burdening the operator for years. (This means, for example, that after a pit-type landfill has been filled, it will be planted with vegetation after placing a top seal, lm soil will be planted.) As a result, depositing what was previously inexpensive is by no means an

4. In densely populated small countries, the landfill of waste is scarce, and the associated environmental rule prevents the public from creating another landfill.

It is clear from the above that waste disposal has been in a state of crisis in the last decade and urgent solutions need to be found. The obvious idea is to reduce the amount of garbage

The waste management strategies of the most advanced countries are as follows;

- reduction of waste production,

- recycling of recyclable waste and only

- final disposal of the waste.

In Hungary, according to the law, only waste may be disposed of, for which the technical or economic possibilities for the utilization of the material or energy source are not yet available or the costs of utilization are disproportionately high compared to the costs of disposal.

Given that measures to reduce communal "waste dumps" are ineffective and that the amount of solid municipal waste per capita continues to increase, recycling of waste has come to the fore,

Recycling requires selective waste collection, which is still around 10% in Hungary, while

In the greenest Member States of the EU this is also 5% (Belgium, Germany).

In Hungary, the vast majority of solid municipal waste goes to landfill, and fractionation and recycling of landfill waste is crucial to extend the life of landfills.

By separating solid municipal waste, basically three fractions can be obtained:

1. Inert waste fraction (glass, metals, building debris), aggregated with non-decomposing materials. Some of these are metals, building materials, can be sorted, recycled using known technologies.

2. Organic waste, nearly 30-50% of municipal waste consists of organic waste (green waste, paper cardboard and other organic waste), its separate treatment is obvious, and today it is a proven solution. The main purpose of organic matter removal is to reduce the weight and volume of the waste and to dispose of the residue. These goals are achieved by two fundamentally different methods, namely thermal or biological treatment

3, Composite waste, composite materials, recovery from waste, separate treatment,

4. Plastic waste, 15-26% by weight of solid municipal waste, but 3% ~ 5% by volume of the fraction to be deposited is plastic waste, which according to current theories decomposes over hundreds of years (300 years), en-4. ••• γ '...

There are numerous patents dealing with municipal waste management in the following references.

Burning Solutions Prayers Exposed

1. U.S. Patent No. 157,519. Before working on a Hungarian patent bej, you first wanted to change this garbage, first it was prewashed, see! it was separated, then the raw waste was kiln-dried, mechanically further shredded and then incinerated, possibly after removal of metallic materials,

2. No. 184,205. According to Hungarian patent application, garbage is disposed of by incinerating solid waste with oxygen in a mine furnace to provide, on the one hand, molten metal and slag and, on the other hand, a chemical raw material

3. U.S. Pat. A Hungarian patent describes the incineration of pre-treated industrial waste, where the pre-treatment is deep-frozen, shredded and then burned. Pretreatment may occur

1) during aeration, with the waste being steamed, or 2) the waste is treated with additives or acidifying agents.

4. P9901186. Hungarian patent application describes the garbage or scraping! the sludge is plolyzed in an oxygen-deprived atmosphere, the solids being mechanical. The coarse fraction of the screening is fed to a metal reactor, the fine fraction is blown into a metal bath by a carrier gas and partially used as a combustion gas in the pyrolysis gas.

Even with the above solutions, it has been recognized that the inhomogeneity of the eyes complicates its treatment, and that it is expedient

thinking about energy recovery :; however, these prophecies have resulted in relatively few practices that are economically viable.

A significant disadvantage of combustion solutions is that the emitted combustion products contain a large number of air pollutant components, which makes it understandably hostile to the incinerators in the surrounding population. There are strict regulatory requirements for emissions which require the use of costly purifiers. State-of-the-art plants utilize the hot, fossil fuels released by combustion and increase their economy. The remaining ash is usually disposed of in landfills or used for construction purposes with some restrictions.

Biological waste management is also known,

Biological waste management includes all processes whereby organic and inorganic materials in waste are transformed or degraded by micro-organisms or their enzymes. These processes can take place in the presence of water in an aerobic (oxygen is also involved in the reactions) or anaerobic (in the absence of oxygen) composting, which is a traditional operation in agriculture, but has only begun to gain ground in the treatment of municipal waste in recent decades. In the presence of air, compost containing valuable organic and inorganic materials is formed in addition to carbon dioxide and water decomposition products, which can be used for soil improvement.The anaerobic process works by excluding air, previously used to treat sewage sludge, and more recently to decompose organic waste in households. In the process of excluding air, biogas containing methane and carbon dioxide is formed from some organic matter and compost from other parts. has similar properties.

However, with these methods, only a fraction of the solid municipal waste components can be treated, with respect to the presence of significant amounts of metal and plastics. In biological waste, we have not found that the plastic content of the light fraction from solid municipal waste is economically, nor is it suitable for processing in terms of environmental technology. Therefore, it is an object of the present invention to provide a solution for the treatment of solid municipal waste from plastic asphalt, in an environmentally friendly manner, and economically energy efficient in the process, which enables the pH to increase; , p products are valuable as a second source of energy. and mine residues are inert and their environmental impact is significantly reduced.

^; Plastics, especially PET bottles, which are selectively collected from municipal solid waste, are processed and used as secondary raw materials.

By depositing municipal waste in landfills, currently unsatisfactory quality secondary raw materials are produced by sorting the plastic waste and cleaning it before processing, at a considerable cost. A further disadvantage is that conventional waste water treatment without a combined recovery process is expensive and unsafe.

It is a further object of the present invention to provide a solution to the above-mentioned disadvantages and disadvantages of the prior art,

The fraction which is contaminated with the known "municipal waste" after the sorting of the known rotating grate waste is further fractionated or washed through a fluidized bed separation system. A static biogas production unit without a moving element is used to process the washing water of the contaminated plastic waste that we have identified and certified origin.

The unit for biogas and compost production consists of a vertically arranged homogenizing tank H and a slurry reactor / fermentor operating in two cascades.

The H homogenizer tank is known per se; from the 5-15% by weight dry solids wash water, the dry matter settles slowly, so the mixing element is intermittently slow and plays a significant role along with the liquid level of the F1 and F2 fermentor tanks.

The H homogenizer tank and the Ft and F2 fermenters are constructed as gas-tight steel tanks; height to diameter ratios preferably reach 6: 1. Fermenter tanks FI and F2 are provided with plates up to 32 spaces, forming cavities extending up to about 2/3 of the diameter. The pressure of the gas formed in said cavities, when reaching the hydrostatic pressure, bursts out of the baffles 32 under the baffles, maintaining both the transverse and the upstream flow used in the artificial gas flow systems. Thus, the stirring is provided by the gas bubbles bursting out of the cavities, while the temperature required for the activity of the microbial strains is provided by the exothermic reactions themselves.

The operation of the fermentor tanks F1 and F2 is intermittent and, as in the case of the homogenizer tank H, it is discharged through conduit 30, at the lower point here the K1-K3 conduits as well as at the lower points of the chlorinated sludge dry compost drain fovábbhasznosításra. The

704377, at the lower points of the DS are the discharge lines 33 and. There are 29 biogas pipelines for biogas.

Any known drum dryer may be used to reduce the moisture content of the material from the washer to the dryer 82, or a lower air blower dryer suitable for intense shaking of the set. The air pre-heater, to be further elaborated below, will be utilized in part by utilizing the heat content of the flue gas from the main technology, ie the treatment of the plastics.

The FA fine shredder unit forms mills having a particle size of 10-16 mm, the FA fine shredded feed material forming part of said FA unit partly due to the above coarse ground. Thus, the 10-16mm particle size, agglomerate, or shavings are the well-prepared material to be treated in the main technology field. This is transported to cyclone 12, from where it can be transported for further treatment, bagged in the figure.

90-97% of the material to be treated is a plastic polymer and the production of a secondary energy carrier derived therefrom is one of the main economic objectives of the present invention. As is known, the plastic adheres to all the metal particles and fine dust despite the pretreatment. By sampling secondary carbon, we determine its relevant valuable, potentially harmful metal content. The high oil yield of the process is a function of the purity of the material fed to the process. It should be noted that, while avoiding manual sorting, however, it requires intensive physical work to isolate heavily contaminated materials, used products advantageously in their material, and a second raw material unsuitable for the production of petroleum gas products. In the main part of the process, after oil treatment, the oil yield is between 50-80%, the decomposition gas is 10-15%, and this high carbon residue, which reaches 98%, is 5-1%.

The main apparatus is essentially a furnace, as shown in more detail in Figure 3, having the following structure.

The base of the device is a horizontal so-called. pan heat transfer plane

S ·,. '· Surface, which is the lower chamber and the lower member of the closed chamber 13 formed above it. Flat cauldron.

The closed chamber 13 has a mixing device with a lower inlet shaft for actuating the excavator blade. Stable pressure (0-50 mbar) is created in the closed chamber 13 and the processing temperature is maintained at 42 to 55 ° C, which is provided by the controlled operation of the block burners 14. Biogas and decomposition gas from plastics are used as fuel for the block burners 14. Typically, the gas composition is approx. 10% methane, with significant C4H5 and C4H12 content of up to 40%, thus significant formation of unsaturated compounds with minimal H2 formation through lane ruptures.

A dispenser is disposed on the doom above the closed chamber 13 for a min. Conical container 17 with a 70 ° component, preferably having a vertical plug. The closed chamber 13 is closed by a sluice 16 from the container 17. A rectifying column 18 is connected to the dome at its upper point by a flange, into which hot gases and oil vapors obtained as products of the closed chamber 13 flow vertically. The products exit above the dew point of heavy oil, above 420 ° C. Heavy oil vapors cannot be precipitated in the column during their flow, since the drip trap 15 prevents it from dripping, the fraction drops back into the closed chamber 13 and there is a cracker. Thus, a true product above 30 ° C dew point is not isolated. The ascending current of the rectification column 18 is also braked by a transverse tube bundle.

The bubble tray zone 19 of the rectifying column 18 is surrounded by a cooling jacket, which serves as a buffer for the batch cooling. The zone containing the bubble trays 19 is divided into two sections, which are: the upper tray receives the current of the reflex heart chicks 21, 23, which are captured in the lower tray 24, 25, and from where the product • X «*

704377? Dons are stored in storage. Reflex circuits also contain 20.22 reflex coolers. The reflex circuits are set depending on the range of the expected oil fractions. This means increasing the yield of the marketable product that we want to create in larger quantities. The equipment also comes with a tray 26, a tub 27 and a conveyor belt 28 for product removal,

The optimum spacing of the drip trays we consider is 170 mm, which is supported by the consideration that the spray consisting of rising cross-flow steam and its own precipitate in the zone designated for fractional separation ensures the efficiency of the distillation mainly through stable equilibrium. This means that the temperature in the zone is stabilized so that, under steady flow, the liquid mixture can be recovered in a closed boiling range, while the number of solution lines is determined by the demands of the separated products.

The milk product of the AA 18 rectifying column flows to the GK compressor station via a gas line formed on the doom. The condition of the compressor operation is a continuous, uniform gas pressure of at least 4 mbar, the parameters of the GK compressor station are selected according to the invention. adjusts the pressure level of the combustion plant.

By pre-mixing the gases from the fermenter and the plastic crackers, the liquid phase formed in the gas tank of the block and the fuel to be discharged can be controlled by blowing a column of Inert gas.

<· 4 solid slag containing SS% carbon, ie almost pure coal dust. Due to its high degree of homogeneity, the material has a particle size range of 7-300 µm, with a low particle size to 300 µm ratio.

Since the amount produced in the Production Unit is 100-200 kg / h, it is therefore possible to use a hydraulic rammer, although the energy loss during operation is significant, the briquette quality is also poor / the product is mild /. It is advisable to set up the mechanical equipment, which is essentially an eccentric press with an electric drive.

The material for briquetting is, on the one hand, the abovementioned pulverized coal, as well as reeds, straw daggers / seeska. It is a requirement for the chopper to provide a maximum chipping size of 12 mm, which is achieved by grinding stems with a maximum moisture content of 14%. The calorific value of the vegetable raw material is less than 16-18 MJ / kg, but the calorific value of the coal powder is above 30 Md / kg. The product obtained is excellent in a mixing ratio of 50-50% by weight, when its calorific value reaches 25 MJ / kg and its hardness is close to that of a coal briquette. The powder has a good bulk filling, the plant carrier forms a product that is approximately cohesive and has a good disintegration with a consistent consistency.

The operation of the agitator shown in Fig. 5 is to operate the next lower level of the container emptying, which is pre-filled in a weighing tank, which is then weighed, and, in addition to the technology, is weighed on a volumetric basis. , since the density of the bulk coal dust is constant. The amount added is 410-950 g / L depending on the pretreatment

After dosing, the mixing time is 120-180. By opening the lower point, briquetting continues and batch operation is warranted to ensure consistent product quality.
