By this, the overall work routine ends.

The working principle of the garbage and sludge shock wave anaerobic pyrolysis gasification power generation and heat supply comprehensive utilization system is as follows:

as mentioned above, the garbage, sludge and shock wave anaerobic pyrolysis gasification power generation and heat supply comprehensive utilization system is divided into three main procedures: firstly, pyrolyzing and drying by shock wave; secondly, rotary pyrolysis gasification; thirdly, oxygen-enriched incineration, volume reduction and heavy metal solidification of the carbide slag.

Firstly, a shock wave pyrolysis drying principle:

the garbage and sludge are impacted and vibrated by supersonic shock waves in a working medium with high temperature of 300-600 ℃ and pressure of 0.1-1 MPa (MPa) of a shock wave furnace (10) to be cracked, and the working medium and the shock waves are subjected to supersonic flight together to generate thermal barrier, so that water holding structures such as colloidal floc, cell walls (membranes) and the like of the garbage and sludge are destroyed and disintegrated, and the 'bound water' which is difficult to remove originally in a mechanical and evaporation mode is completely released and gasified; the garbage and the sludge are pyrolyzed and dried by shock waves to form dry slag, and the water content is reduced to below 20 percent.

The working principle of rotary pyrolysis gasification is as follows:

the dried slag is pushed and rolled in a working medium with the high temperature of 500-700 ℃ and the pressure of 0.5-1.5 megapascals (MPa) of a rotary furnace (12) under the action of mechanical force, fully contacts with the working medium for 40-50 minutes, the molecular structure is cracked, H, O, Cl in organic matters and other gasifiable components are gasified to generate combustible flue gas to overflow; the carbon content in the carbon residue is more than 75%.

Thirdly, carbon residue oxygen-enriched incineration, volume reduction and heavy metal solidification principles:

the carbide slag is subjected to oxygen-enriched incineration, volume reduction and heavy metal solidification in a carbide slag incinerator (14) to generate flue gas mainly containing carbon dioxide and slag mainly containing metal and heavy metal oxide; the flue gas overflows and slag remains; as the carbon content in the carbide slag accounts for more than 75 percent, the carbon is oxidized to generate carbon dioxide flue gas to overflow, and the volume is reduced by more than 75 percent.

Heavy metals are harmful pollution sources in free states and pollute underground water and soil; the underground water is polluted by heavy metal, thus harming the health of residents; the soil is polluted by heavy metal to cause potential safety hazard of grains; and when heavy metal is fully oxidized to generate heavy metal oxide, the heavy metal is solidified in inorganic salt, and the chemical property is changed, so that the hidden danger of heavy metal pollution is eliminated from the source.

Fourthly, the principle of recycling the waste heat of the flue gas is as follows:

the non-combustible shock wave furnace smoke needs to be cooled before various harmful components are burnt and solidified at ultrahigh temperature and enter a subsequent purification procedure; before the combustible flue gas of the rotary furnace is separated and extracted by three phases, the temperature of the combustible flue gas also needs to be reduced; the flue gas temperature is reduced and associated superheated steam is generated by heat exchange of the flue gas waste heat recycling boiler A (16) and the flue gas waste heat recycling boiler B (28), and the superheated steam can be used for generating work and power for a turbine generator 43 group; the huge heat energy is utilized to create huge financial benefits, so that the energy is not wasted.

The flue gas waste heat recycling boiler A (16) and the flue gas waste heat recycling boiler B (28) are in double-drum natural circulation; after the high-temperature flue gas enters the flue gas waste heat recycling boiler, the temperature of the flue gas is reduced to be below 110 ℃ through radiation heat exchange, superheater overheating, convection heat exchange surface heat exchange and economizer heat exchange; then, the subsequent procedure is carried out for purification treatment; the boiler feed water pump sends feed water to the economizer, after heating to a certain temperature in the economizer, feed water enters the drum, absorbs the heat of high-temperature flue gas at the water-cooled wall to form a steam-water mixture, then rises to the upper drum, steam flows to the superheater from the upper part of the drum through the steam-water separation device, saturated steam becomes superheated steam after the superheater continues to absorb heat, and then the superheated steam is sent to the turbo generator unit (43) to do work and generate power.

Fifthly, the utility model discloses the principle of the processing rubbish does not produce dioxin hypertoxic:

basic preconditions for the virulent generation of dioxin: firstly, chlorine gas exists; secondly, a large amount of oxygen exists; thirdly, a metal oxide catalyst is added; fourthly, the temperature is within the range of 250-500 ℃.

In the three main procedures of the garbage and sludge shock wave anaerobic pyrolysis gasification power generation and heat supply comprehensive utilization system:

the first step is main procedure, shock wave pyrolysis drying: in this stage, chlorine is primarily gasified and separated from the plastic, and the working medium does not contain oxygen and metal oxide, so the basic precondition of generating dioxin with high toxicity is not provided; therefore, chlorine can only be self-combined and exists in the flue gas of the shock wave furnace in the form of chlorine molecules; when the shock wave furnace flue gas is subjected to ultrahigh-temperature incineration in the flue gas incinerator 10, Cl and H undergo a chemical reaction to generate HCl, and Cl is solidified in HCl; thereafter, there was no independent presence of Cl, and there was no source of dioxin virulent generation.

The second step is main procedure, rotary pyrolysis gasification: in the working stage, because of long time, all organic matters including plastics are thoroughly pyrolyzed and gasified, and although oxygen is generated, the basic precondition of generating dioxin with severe toxicity is still not provided because the temperature is higher than 500 ℃ and no metal oxide catalyst is used; therefore, chlorine element can only be self-combined and exists in the smoke of the rotary furnace in the form of chlorine molecules, and the chlorine gas becomes a part of the fuel gas and enters a fuel gas generator set to work and generate power through three-phase separation; because the main component of the fuel gas is H, O, Cl, Cl still reacts with H to generate HCl during work burning; thus, Cl is still solidified in HCl; therefore, the independent Cl is not existed, and the source of dioxin virulent generation still does not exist, so that the possibility and the probability of dioxin virulent generation are fundamentally eliminated.

The third step is main procedure, oxygen-enriched incineration of carbide slag, volume reduction and heavy metal solidification: at this time, the carbide slag is completely free of chlorine.

According to the three steps of main procedures, the garbage and sludge are treated by the utility model, the basic precondition that dioxin virulent strain is generated is completely avoided, and all the dioxin virulent strain has no possibility and probability of being generated; even if the hidden dangers of dioxin hypertoxicity and heavy metal pollution existing in the original garbage are overcome, the hidden dangers can be corrected by the large smelting furnace.

The utility model has the advantages of

Firstly, core technical equipment is manufactured at home, and a complete set of equipment can be completed at home without being limited by foreign countries.

Two, the utility model discloses compare in foreign system technical design such as Europe and America, reasonable more, comprehensive, perfect, system function is stronger, technically is in complete leading position.

And thirdly, the device has simple and practical structure, simple operation, convenient maintenance and low requirement for garbage sorting, and can effectively reduce the burden of social garbage sorting.

Fourthly, the garbage and sludge treatment realizes complete harmlessness and volume reduction; zero pollution and zero emission, the furnace slag can be used as a raw material for building material production, no land occupation is needed for landfill, and precious land resources can be saved.

And fifthly, 100 percent of resources are comprehensively utilized, the power generation and heat supply capacity is strong, and the method not only has good ecological environmental benefit and social benefit, but also has great economic benefit.

The six functions are integrated, the garbage and the sludge are eaten through, the functions are complete, and the benefits are obvious; the harmlessness, volume reduction and resource utilization are really realized; the exhaust index can meet the strictest environmental standard requirement in the world, namely no dioxin virulent, no heavy metal pollution and other types of secondary pollution; the method is comprehensively popularized and popularized, and can solve the environmental protection problem of urban and rural areas in China at one time.
