Description

Mobile epidemic disease poultry and waste harmless incineration treatment device

Technical field

The invention belongs to the field of sanitation and environmental protection, and in particular relates to a mobile harmless incineration treatment device for poultry and livestock with diseases and wastes.

Background technique

At present, preventing the spread of bird flu, SARS, and mad cow disease is a concern of all walks of life, and the harmless treatment of diseased poultry and livestock is also increasingly attracting people's attention. Epidemic poultry and livestock and related wastes contain viruses, bacteria and toxic and harmful substances, which will become the breeding source of pathogens and the source of virus diffusion through mosquitoes, mice, birds, etc., especially the pathogens of "bird flu" and "atypical infection" Pneumonia” pathogens may spread the disease through the air, therefore, the diseased poultry and livestock must be treated in a harmless and reduced amount.

The treatment methods for poultry and livestock with epidemic diseases generally include landfill treatment and incineration treatment. The usual landfill treatment is cumbersome, and there are problems of pre-treatment and land occupation. In addition, the landfill poultry will also pollute the groundwater source; incineration treatment is simple and reliable, and general incineration can destroy 99.99% of organic matter. The incineration of livestock generally adopts the method of fixed-point incineration, that is, transporting the livestock infected with epidemic diseases to a fixed place, using larger incineration equipment for incineration, or directly digging pits at fixed points, burning them in the pits, and then covering them with soil. buried.

The fixed-point incineration treatment of epidemic poultry and livestock has the following disadvantages: there are hidden dangers of virus and bacteria spreading during the transportation of poultry and livestock, especially the "bird flu" pathogen, "atypical infectious pneumonia" virus, etc. If the seal is not tight or the sealed bag If it is damaged, it may spread through the air; at the same time, the fixed-point incineration plant has a long construction period, and it is difficult to meet the needs of emergency outbreaks such as "bird flu" and "atypical infectious pneumonia"; larger incineration equipment not only requires large investment and high cost, It is inconvenient to carry and move, and cannot meet the requirements of rapid, safe, convenient and fast processing for scattered farms. On the one hand, the method of digging pits and burning leads to the pollution of soil and groundwater sources; on the other hand, this method is prone to incomplete combustion, which provides opportunities for criminals to dig out the unburned poultry for processing and then enter the market , and the flue gas after excavation and combustion has not been post-processed, and is directly discharged into the atmosphere, in which the incomplete combustion of toxic gases and dust causes secondary pollution of the environment.

At present, some domestic waste incinerators are mostly fixed structures, which cannot be easily moved to the place where the epidemic occurs. Moreover, these waste incinerators have not set up a tight sealing structure for poultry and livestock with strong virus transmission and their waste. Therefore, these waste incinerators are not suitable for treating epidemic diseases, livestock and their wastes.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing.

As shown in Figures 1, 2, 3, 4, and 5, the rotary ring (7-13) and the gear of the support (7-14) provided on the rotary section shell (7-12) of the rotary kiln (7) or The rollers are matched and connected, driven by a motor, the motor speed is steplessly adjustable, and the actual operation is controlled at 3 to 5 revolutions per minute. The rotary kiln (7) on the flatbed trailer (1) is inclined with a high front and a low rear. By adjusting the height of the supporting legs (1-1) of the flatbed trailer (1), the inclination angle of the rotary kiln (7) can be controlled at 1~3°.

The ash melting processing component (8) is directly connected with the rotary kiln (7), and the unburned ash delivered from the rotary kiln (7) flows into the combustion chamber (8-6) through the passage of the partition plate (8-5) ), a regenerative burner (9) is provided on the wall of the combustion chamber (8-6), and the regenerative burner (9) can provide high-temperature flue gas at 1200°C to 1400°C to melt the aforementioned ash state in order to facilitate slag discharge, and the ash is discharged from the slag outlet (8-7) in liquid form; the flue gas from the rotary kiln (7) and the ash melting treatment component (8) and the small particles of ash and fly The ash is discharged from the smoke exhaust (8-1), and enters the cyclone reburner (10) tangentially. The small particles of ash and fly ash separated and collected by the cyclone reburner (10) pass through the ash return valve (10-6) and the ash The slag return pipe (10-7) enters the combustion chamber (8-6) from the ash and slag circulation (8-8) for melting in batches again.

The working process of the mobile epidemic disease, livestock and waste harmless incineration treatment device is: the epidemic disease, livestock and waste are placed in the silo (4), pushed by the hydraulic station (2), and enter the rotary kiln through the feeding mechanism (5). (7), the high-temperature air burner (6) burns the diseased poultry and livestock and waste in the rotary kiln (7). While the rotary kiln (7) is driven by the motor to rotate, due to the high The rear end is in a low inclined state, so diseases, poultry and wastes naturally move from the front end of the rotary kiln (7) to the rear end, and then the unburned ash naturally flows to the rear end of the rotary kiln (7) to directly communicate The ash and slag melting treatment member (8), and under the heating of the regenerative burner (9), becomes molten and flows out from the slag (8-7); And small particles of ash and fly ash enter the cyclone reburner (10) connected to it through the exhaust smoke (8-1) on the upper part of the ash melting treatment component (8) tangentially, so that the dioxin in the flue gas Pharynx, Harmful components such as furan are decomposed and fully burned, and the ash and fly ash are collected in the conical ash collection chamber (10-5) through cyclone separation, and returned in batches to the ash melting treatment component (8) for melting treatment. The flue gas enters the regenerative air preheater (11) through the exhaust pipe (10-2) of the cyclone reburner (10), and at the same time, the air blown in by the blower (12) also flows through the regenerative air preheater. Heater (11); heat exchange between high-temperature flue gas and air in the regenerative air preheater (11), and then the high-temperature air recovered from the waste heat of the flue gas is discharged from the regenerative air preheater (11) , a part enters the rotary kiln (7) through the pipeline as primary air and secondary air, wherein the primary air is provided for auxiliary fuel combustion and primary air in the high-temperature air burner (6), and the secondary air enters the rotary kiln (7) Turn section (7-5) to provide the complete incineration of epidemic poultry and livestock in the rotary kiln; Another part is sent to regenerative burner (9) and fuel injection combustion (10-3) respectively. After the tail gas flows out from the regenerative air preheater (11), it is directly emptied through the induced draft fan (13) or is emptied from the existing living boiler chimney of the farm.

Since the rotary kiln (7) adopts a segmented air intake structure, the complete combustion of poultry and livestock in the epidemic situation is guaranteed; the waste heat of the flue gas is used to heat the air, so that the present invention can achieve the best combustion efficiency and reduce the amount of auxiliary fuel; at the same time, in the cyclone In the reburner (10), the combustion temperature is increased to reduce the discharge of tar, grease organic matter, and trace organic matter such as dioxin and furan in the flue gas; in addition, the ash and fly ash are separated and collected and melted to complete the removal of viruses and bacteria. Thoroughly decompose, and effectively control the discharge of pollutants such as dioxin and furan in ash and fly ash; therefore, it has the advantages of high treatment efficiency, good environmental protection effect, small investment and low operating cost, and can well meet the " Bird flu", "atypical infectious pneumonia" and other emergency outbreaks.
