Description

High-temperature high-pressure steam type chicken manure cracking treatment device Technical Field The invention relates to the technical field of fecal treatment, in particular to a high-temperature high-pressure steam chicken manure pyrolysis treatment device. Background With the rapid development of the large-scale chicken raising industry, the discharge amount of chicken manure is increased in an explosive manner. According to statistics, the daily manure yield of every ten thousands of laying hens can reach 1.5-2.0 tons, and the annual manure discharge amount of a single field of a large-scale broiler farm is often more than thousands of tons. The chicken manure contains a large amount of organic matters, nitrogen, phosphorus, potassium and other nutritional ingredients, is mixed with undigested feed residues, pathogenic microorganisms, parasitic ova, antibiotic residues and other harmful substances, if the harmful substances are improperly treated, a series of environmental problems can be caused, namely, when the harmful substances are stacked in open air, the odor gases such as ammonia gas, hydrogen sulfide and the like generated by the fermentation of the manure pollute the atmosphere, percolate caused by rain washing can infiltrate into soil and groundwater to cause soil salinization and water eutrophication, the ecological system balance is threatened, and the spread and diffusion of the pathogenic microorganisms can also cause cross infection of epidemic diseases of livestock and poultry, so that economic loss is brought to the breeding industry. At present, chicken manure treatment technology mainly comprises composting fermentation, anaerobic digestion, drying treatment, incineration treatment and the like. Although the composting fermentation technology can convert chicken manure into organic fertilizer, the composting fermentation technology has the problems of long treatment period (usually 20-30 days), large occupied area, easy generation of malodor pollution in the fermentation process, uneven fertilizer efficiency of finished products, difficult thorough inactivation of part of pathogenic microorganisms, and the like. The anaerobic digestion technology can realize biogas recycling, but has higher pretreatment requirement on chicken manure, needs to control solid-to-liquid ratio and carbon-nitrogen ratio, has large equipment investment and complex operation and maintenance, and is not suitable for medium and small farms. Although the water content of chicken manure can be reduced by the drying treatment, the chicken manure is convenient to store and transport, the energy consumption is high, only physical dehydration can be realized, organic matters cannot be decomposed and harmful substances cannot be removed, and the subsequent treatment still has environmental protection risks. The incineration treatment can be quickly reduced and harmless, but toxic and harmful gases such as dioxin, nitrogen oxides and the like can be generated in the combustion process, the environmental protection requirement on incineration equipment is extremely high, the investment and operation cost is high, and the method is difficult to widely popularize in the breeding industry. The high-temperature high-pressure steam cracking technology is an ideal choice for chicken manure treatment by virtue of the advantages of rapid decomposition of organic matters and complete inactivation of pathogenic microorganisms. The technology can quickly crack organic matters in chicken manure into micromolecular matters through the action of high-temperature and high-pressure steam, meanwhile kill bacteria, viruses, parasitic ova and other harmful organisms in the chicken manure, realize harmless treatment, and further process the cracking products into organic fertilizer, biochar or biomass energy so as to realize resource recycling. In the prior art, the stirring and the high-temperature steam supply are separated in the cracking equipment, and although the chicken manure in the pipe can be fully contacted with the high-temperature steam, the chicken manure needs to be mixed and stirred for a long time, so that the treatment period is long and the energy consumption is high. In addition, the defect that feeding, discharging and cracking processes cannot be synchronously carried out exists in a single cracking tank structure, so that equipment operation continuity is poor, and treatment efficiency is difficult to improve. Accordingly, there is a need for a cracking apparatus that solves the above-mentioned problems. Disclosure of Invention (One) solving the technical problems Aiming at the situation, in order to overcome the defects of the prior art, the invention provides a high-temperature high-pressure steam type chicken manure cracking treatment device, which aims to solve the problems in the background art. (II) technical scheme The high-temperature high-pressure steam chicken manure cracking treatment device comprises a
