Abstract
The invention discloses a self-burning device for domestic garbage, which enables the inflammable vapor generated by pyrolyzing garbage to be directly utilized in the burning device. The device is characterized in that the structure comprises: a furnace body, a feeding pipe, an upper thermal air opening, a lower thermal air opening, a high temperature gas outlet, a cinder notch, a heat transfer, a waste heat boiler, a quench tower, a dust catcher, a draught fan, a chimney, a water quench machine and a separator. Heat for the invention can be supplied by burning without needing ant assistant fuel; besides, high temperature air is used for helping the burning, thereby saving oxygen; volatile matters generated from gasification are burned completely in the burning furnace, which has high heat efficiency.
Description
Technical field
The present invention relates to domestic garbage disposer, especially do not need to add the device of the consumer waste self-burning of auxiliary fuel.
Background technology
At present the various incinerators of using all over the world reach nearly 200 kinds, divide but press type of device, are widely used also representative have four classes, that is: fire grate type incinerator, fluidized bed incinerator, rotary kiln incineration stove and shaft furnace type incinerator.
Fire grate type incinerator be develop the earliest, also be to handle the most widely used incinerator in the house refuse at present.The problem that this method exists is: (1) efficiency of combustion is relatively low; (2) with fire grate ash discharge slag, incineration temperature is lower; (3) incineration temperature the end of than makes discharge of harmful gases wayward.In order to address the above problem, many devices have been proposed, as domestic waste incineration, patent disclosure (bulletin) number: CN2395147, dual rotary high temperature incinerator, patent disclosure (bulletin) number: CN2477960 etc.
In order to obtain higher volume reduction rate, improve efficiency of combustion, by hot environment harmful organic principle in the rubbish is realized high destruction clearance, guarantee the stability and the completeness of combustion process, the energy that reclaims in the rubbish is used for heat supply or generating, and the consumer waste incineration technology develops to the gasification and melting incineration direction.
The device of the comparative maturity that the domestic garbage gasification melting incinerating adopts has rotary kiln type and fluidized bed type.Adopt the fluidized combustion mode, to the rubbish fragmentation of will classifying, cause the preprocessing process complex process, equipment is huge and energy consumption is high.Adopt the rotary kiln mode, though strong to the applicability of rubbish, the whole complex technical process of two step method, construction investment and operating cost are big, complicated operation.Therefore, the domestic garbage gasification melting incinerating develops to one-step method.
In various domestic garbage gasification melting incinerating devices, something in common has: the gas row in the incinerator carries out completing combustion to secondary combustion chamber, enters waste heat boiler then and carries out cogeneration or heat supply; Slag and metal cool off rapidly from the cinder notch discharge and by water, and slag that is cooled and metal are selected metal and inorganic residues through separator, the metal recovery utilization, and inorganic residues is as building materials.Difference is the version of incinerator.
Summary of the invention
The present invention is directed to the imflammable gas that refuse pyrolysis produces in the existing domestic garbage gasification melting incinerating stove and in incinerator, directly do not utilized, need in incinerator, to add auxiliary fuel or use the oxygen problem to propose improvement project.
Consumer waste self-burning device provided by the invention comprises: body of heater, charging pipe, the top hot-air mouth, the bottom hot-air mouth, the high-temperature gas outlet, cinder notch, exchanging air, waste heat boiler, quench tower, deduster, air-introduced machine, chimney, the shrend machine, separator, charging pipe is on the body of heater top, two of top hot-air mouths, one of bottom hot-air mouth, logical heat exchanger of high-temperature gas outlet and waste heat boiler, logical again top hot-air mouth of heat exchanger and bottom hot-air mouth, waste heat boiler leads to quench tower, two logical quench towers of polyphone heat exchanger and logical deduster, the deduster bottom is an air-introduced machine, air-introduced machine leads to chimney, cinder notch is at bottom of furnace body, cinder notch connects the shrend machine, and the shrend machine connects separator.
The domestic garbage gasification fusion is to carry out drying garbage, gasification, and combustion on a top from burning, and the bottom carries out carrying out in the incinerator of melt-combustion.
When beginning to handle house refuse, need some combustion-supporting materials that rubbish is lighted, rubbish is lighted the back and is produced high temperature air.House refuse is imported from the incinerator top with the high temperature air that comes out through heat exchanger, they are on stove top and flow down in the process of falling, house refuse is carried out drying by the high temperature air heating earlier, be heated to then and begin pyrolysis when pyrolysis begins temperature, the volatile matter of separating out takes fire when being heated to ignition temperature, the heat that the volatile combustion liberated heat further provides pyrolysis and rubbish to heat up and need.Rubbish after the pyrolysis drops to the bottom of incinerator, is blown into high temperature air in the incinerator bottom, and combustible residuals in secondary completing combustion pyrolysis high-temperature gas that produce, that enter the incinerator bottom and the rubbish provides the ash melting heat dissipation.A high-temperature flue gas part that generates enters heat exchanger and is used for heating the high temperature air that needs, and another part enters waste heat boiler.Exhaust-heat boiler flue gas is discharged by chimney through quench tower, deduster, air-introduced machine.Slag is discharged from cinder notch, and is cooled off rapidly by the shrend machine, and slag that is cooled and metal are selected metal and inorganic residues through separator, the metal recovery utilization, and inorganic residues is as building materials.
The present invention compared with the prior art, the beneficial effect of generation is:
1) heat of domestic garbage gasification fusion needs is provided by its burning, does not need to add any auxiliary fuel, has both realized that the domestic garbage gasification fusion is from burning;
2) use high-temperature air combustion promoter, do not need oxygen;
3) volatile matter of gasification generation all burnings in incinerator, thermal efficiency height.
Description of drawings
Fig. 1 is the consumer waste self-burning device schematic diagram.
The specific embodiment
As shown in Figure 1, consumer waste self-burning device comprises: body of heater 3, charging pipe 1, top hot-air mouth 2, bottom hot-air mouth 4, high-temperature gas outlet 5, cinder notch 6, exchanging air 5, waste heat boiler 8, quench tower 9, deduster 10, air-introduced machine 11, chimney 12, shrend machine 13, separator 14, charging pipe is on the body of heater top, two of top hot-air mouths, one of bottom hot-air mouth, logical heat exchanger of high-temperature gas outlet and waste heat boiler, logical again top hot-air mouth of heat exchanger and bottom hot-air mouth, waste heat boiler leads to quench tower, two logical quench towers of polyphone heat exchanger and logical deduster, the deduster bottom is an air-introduced machine, air-introduced machine leads to chimney, cinder notch is at bottom of furnace body, cinder notch connects the shrend machine, and the shrend machine connects separator.
