Background technology
Along with development and national economy, the raising of living standards of the people, the rubbish output of China has reached 1.5 hundred million tons, and wherein the overwhelming majority is directly stacked and landfill without any processing, not only take the land resource of a large amount of preciousnesses, and brought serious secondary pollution problem.The target that solves garbage problem is to hand over rubbish to subtract appearance, decrement, resource, reach harmless treatment.Comparatively positive method is the compost that burns at present.Burning subtracts appearance, decrement degree height, but the calorific value of the present domestic waste of China is low, causes burning process energy consumption height.When adopting the burning electricity generation technology, recycling efficient is low, and is with high costs.According to the basic composition situation of present China rubbish, the comprehensive treatment technique that adopts compost to combine with simple burning has reduced investment, resource utilization degree height, characteristics that processing cost is lower.But because garbage compost factory generally adopts the simple burning mode that falls behind to handle flammable organic matter at present, the burning condition instability, flue gas is handled also very imperfection, has caused the secondary pollution of tail gas to fertilizer product and atmosphere.
Summary of the invention
The purpose of this utility model is that design a kind ofly can be carried out burning disposal to the flammable organic matter in the domestic waste, and can provide necessary heat for the compositing system operation, and can solve the refuse pyrolysis incinerator of problem such as disposal of refuse foul smell.
Pyrogenation incinerator of the present utility model adopts vertical two sections type of furnaces, its structure comprises hopper, pyrolysis vaporizer, gas-phase combustion chamber and flue, it is characterized in that the pyrolysis vaporizer bottom is provided with the syllogic reciprocal grate of each section drive, be followed successively by the dryer section fire grate, the pyrolysis section fire grate, the burning segment fire grate, each fire grate bottom is provided with air compartment respectively, has a necking down aditus laryngis between pyrolysis vaporizer and the gas-phase combustion chamber, be provided with secondary eddy flow air inlet at the aditus laryngis place, the top of pyrolysis vaporizer is arch, the angle of its rear arch and fire grate is 5～10 degree, 1/3～1/2 place that is projected in the dryer section fire grate of rear arch is provided with the air distributing device as the tail gas cooling in the flue at rear portion, gas-phase combustion chamber.
Said secondary eddy flow air inlet can be provided with 2～3 rows up and down, the cloth of its adjacent row's blast pipe is set as the intersection of 60～90 degree, respectively with tangential direction air intake in stove, thereby forms eddy flow, realize that pyrolysis gas mixes with the abundant disorder of air, reach completing combustion.
This pyrogenation incinerator burning required air, the air that promptly feeds air compartment, secondary eddy flow air inlet and air distributing device can be from rubbish storage bin or refuse classification place or refuse fertilizer fermentation place introducing, the air that contains frowziness that these are located from rubbish storage bin, refuse classification place or refuse fertilizer fermentation place etc., after this pyrogenation incinerator is handled, can remove its stink, eliminate its pollution environment.
Pyrogenation incinerator of the present utility model, adopt the syllogic reciprocal grate with and furnace type structure, can improve the heat reflection performance of burner hearth greatly and to the drying capacity of material; Secondary eddy flow air inlet between pyrolysis vaporizer and the gas-phase combustion chamber can guarantee that the combustible gas that the pyrolytic gasification section produces fully burns; The air that contains frowziness that the inside cloth wind of pyrolysis vaporizer and gas-phase combustion chamber is located from rubbish storage bin, refuse classification place or refuse fertilizer fermentation place etc. had not only been realized the pyrolytic gasification of rubbish and gas phase completing combustion but also had been eliminated airborne stink; Flue is provided with air distributing device at the rear portion of gas-phase combustion chamber, to the tail gas cooling, simultaneously air is played deodorization, can be other technical process after heat exchange thermal source is provided.
Description of drawings
Fig. 1 is the structural representation of refuse pyrolysis incinerator of the present utility model.
The specific embodiment
Be described in further detail below in conjunction with the CONSTRUCTED SPECIFICATION of accompanying drawing embodiment of the present utility model:
Present embodiment is a kind of pyrogenation incinerator that can be used for the burning disposal domestic waste, and its structure as shown in Figure 1.This refuse pyrolysis incinerator is vertical two sections type of furnaces, comprise hopper 1, pyrolysis vaporizer 2, gas-phase combustion chamber 6, flue 8, the bottom of pyrolysis vaporizer 2 is provided with reciprocating fire grate, fire grate is divided into three sections, begin to be followed successively by dryer section fire grate 9, pyrolysis (gasification) section fire grate 10, burning segment fire grate 11 from charging aperture, fire grate drives adjustable-speed by hydraulic system 13; Be provided with in the bottom of each fire grate 12, wind of air compartment by air compartment 12 in fire grate is sent into stove; Above pyrolysis vaporizer 2, be gas-phase combustion chamber 6, form a necking down aditus laryngis 3 between pyrolysis vaporizer 2 and the gas-phase combustion chamber 6, be provided with upper and lower two row's secondary eddy flow air inlets 4 at this aditus laryngis place, its upper and lower row's intake stack is the 90 degree angles of the crossing, secondary wind flows in the stove with tangential direction and forms eddy flow, pyrolysis gas enters gas-phase combustion chamber 6 behind the secondary wind eddy flow air distribution of aditus laryngis, discharge by flue 8 by the flue gas that 6 burnings of gas-phase combustion chamber are produced, in flue 8, be provided with air distributing device 7 as the tail gas cooling.Body of heater is installed on the platform 16.
