Description

Portable eqpidemic disease fowl poultry and refuse innoxious burning treating apparatus
Technical field
The invention belongs to health and environmental protection field, relate in particular to portable eqpidemic disease fowl poultry and refuse innoxious burning treating apparatus.
Background technology
Prevent that at present diffusions such as bird flu, SARS, rabid ox disease from being the problem that various circles of society pay close attention to, the harmless treatment to eqpidemic disease fowl poultry also is subjected to people's attention just day by day.In the eqpidemic disease fowl carcass and relevant discarded object contain virus, bacterium and poisonous and harmful substance, can grow source and viral diffuse source by what mosquitos and flies, mouse, birds etc. became pathogen, " bird flu " pathogen particularly, " SARS " pathogen, might pass through the air borne disease, therefore, must carry out innoxious, minimizing processing to eqpidemic disease fowl poultry.
Treating method to eqpidemic disease fowl poultry generally has landfill disposal and burning disposal.Common landfill disposal is cumbersome, has the problem of processing in early stage and land occupation, and the fowl of landfill poultry also can pollute underground water source in addition; Burning disposal is then simple and reliable, general burning can destroy 99.99% organic matter, but the burning disposal of eqpidemic disease fowl poultry generally adopts the method for fixed point burning at present, the fowl poultry that is about to plant's infection eqpidemic disease is transported to a fixing place, utilize relatively large burning facility to carry out burning disposal, perhaps directly fixed point is digged pit, and cheats interior burning, covers native landfill then.
Eqpidemic disease fowl poultry fixed point burning disposal has following weak point: the hidden danger that has virus, bacterium diffusion in the fowl poultry transportation, " bird flu " pathogen particularly, if " SARS " virus etc. poorly sealed or sealing bag is damaged, may be passed through air borne; The incineration plant of fixing a point the simultaneously construction period is long, is difficult to adapt to resemble " bird flu " needs of " SARS " so urgent epidemic situation outburst; Relatively large burning facility needs not only that investment is big, cost is high, be inconvenient to carry move, plant's needs that can not satisfy distributes looses are rapid, safely, processing requirements quickly and easily.The method of burning of digging pit has caused the pollution of soil and underground water source on the one hand; On the other hand, this method is easy to take place imperfect combustion, thereby for the lawless person offers an opportunity, excavate out to process once again and come into the market burning not most bird, and the gas fume after burning of digging pit is not passed through post-processed, directly enter atmosphere, wherein imperfect combustion toxic gas and dust cause the second environmental pollution problem.
Some domestic garbage disposal incinerators are to adopt stationary structure mostly at present, can easily not move to the epidemic situation scene, and, these incinerators are not provided with tight hermetically-sealed construction at having propagated fowl poultry of strong virus and refuse thereof, in processing procedure, produce easily the leakage of harmful substance and pollute, thereby these incinerators and be not suitable for handling eqpidemic disease fowl poultry and refuse thereof.
Summary of the invention

The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in Fig. 1,2,3,4,5, the swivel becket (7-13) that rotary kiln (7) is provided with on rotational segment shell (7-12) matches with the gear of bearing (7-14) or running roller and is connected, adopt motor-driven, motor speed is stepless adjustable, is controlled at 3~5 rev/mins during actual motion.Low skewed in high back before rotary kiln (7) is on platform trailer (1), the height of the supporting leg (1-1) by regulating platform trailer (1) can be controlled at the inclination angle of rotary kiln (7) 1~3 °.
Ash melting is handled member (8) and directly is connected with rotary kiln (7), the unburnt lime-ash that sends from rotary kiln (7) flows in the combustion chamber (8-6) from the passage of dividing plate (8-5), the wall of combustion chamber (8-6) is provided with heat-storage type burner (9), heat-storage type burner (9) can provide 1200 ℃~1400 ℃ high-temperature flue gas to make aforementioned lime-ash be in molten condition so that deslagging, and lime-ash is discharged from slag-drip opening (8-7) with liquid form; From rotary kiln (7) and ash melting handle the flue gas that member (8) comes out and the granule lime-ash that carries, flying dust is discharged from exhaust opening (8-1); tangentially enter whirlwind burner (10) again, the whirlwind granule lime-ash and the flying dust of burner (10) separated and collected again enters the interior melting batch processing of combustion chamber (8-6) through lime-ash returning charge valve (10-6) and lime-ash refeed line (10-7) once more from lime-ash circulation port (8-8).
The course of work of this portable eqpidemic disease fowl poultry and refuse innoxious burning treating apparatus is: eqpidemic disease fowl poultry and refuse place the interior promotion by Hydraulic Station (2) of feed bin (4) to enter in the rotary kiln (7) via feeding mechanism (5), high-temperature air burning device (6) makes eqpidemic disease fowl poultry and refuse in rotary kiln (7) internal combustion, when rotary kiln (7) is by the motor-driven rotation, because rotary kiln (7) is the front end height, the heeling condition that the rear end is low, so eqpidemic disease fowl poultry and refuse move on to the rear end from the front end of rotary kiln (7) naturally, unburnt then lime-ash flows to the ash melting that directly communicates with the rear end of rotary kiln (7) naturally and handles in the member (8), and becomes molten state flow out from slag-drip opening (8-7) under the heating of heat-storage type burner (9); Flue gas that produces in eqpidemic disease fowl poultry and the incineration of waste process and granule lime-ash, flying dust are handled the exhaust opening (8-1) on member (8) top and are tangentially entered the whirlwind that is attached thereto burner (10) again by being positioned at ash melting; make in the flue gas harmful components such as De Er Evil pharynx, furans obtain that secondary decomposes and fully burning; and lime-ash and flying dust be collected in the taper lime-ash collecting chamber (10-5) through cyclonic separation, return ash melting in batches and handle member (8) melt process.Flue gas through whirlwind again the smoke exhaust pipe (10-2) of burner (10) enter regenerative air preheater (11), meanwhile the air that is blown into by air blast (12) also flows through regenerative air preheater (11); High-temperature flue gas and air carry out heat exchange in regenerative air preheater (11), having reclaimed the high temperature air behind the fume afterheat afterwards discharges from regenerative air preheater (11), a part enters in the rotary kiln (7) as primary air and auxiliary air by pipeline, wherein primary air offers auxiliary fuel burning and the wind in the high-temperature air burning device (6), and auxiliary air enters the rotational segment (7-5) of rotary kiln (7) so that the burning fully of epidemic situation fowl poultry in the rotary kiln to be provided; A part is given heat-storage type burner (9) and spraying burner (10-3) respectively in addition.Tail gas flows out after directly emptying or from plant's existing boiler for domestic chimney emptying of air-introduced machine (13) from regenerative air preheater (11).
Because rotary kiln (7) adopts the subsection-inlet structure, guaranteed the completing combustion of epidemic situation fowl poultry; Utilize fume afterheat to add hot-air, make the present invention reach best efficiency of combustion, and reduce the consumption of auxiliary fuel; Simultaneously, improve ignition temperature in the burner (10) again at whirlwind, tar, grease organic matter are with the discharging of trace organic substances such as Er Evil pharynx, furans in the minimizing flue gas; In addition, lime-ash, flying dust are carried out separated and collected and melt process, finish the thorough decomposition of virus, bacterium, and control the discharging of pollutants such as lime-ash, flying dust Zhong Er Evil pharynx, furans effectively; Thereby have treatment effeciency height, environment protecting is good, investment is little, operating cost is low advantage, can satisfy the instructions for use of urgent epidemic situation outburst such as " bird flu ", " SARS " well.
