Abstract
The invention relates to a harmless treatment device for dead pigs and solves the problems that the conventional dead pig treatment device and technology are low in heat utilization efficiency, and toxic gas is emitted during the dead pig treatment process. The device comprises a burning furnace for providing hot air, a chopper for chopping materials and a drum used for stir-frying and conveying chopped materials, wherein a discharge port of the chopper and an air outlet of the burning furnace are connected with a head end of the drum; a solid substances outlet is formed in the bottom of the tail end of the drum; an exhaust port is further formed in the tail end of the drum and connected with a tail gas treatment device; and the solid substances outlet in the tail end of the drum is further connected with a fuel inlet of the burning furnace through a conveying device. Besides, the chipper is arranged in an isolation room, and combustion air of the burning furnace is led from the isolation room and performs displacement on air in the isolation room. The harmless treatment device for the dead pigs has a good sterilizing effect, reduces energy consumption of dead pig treatment, and improves the heat utilization efficiency; and further, air in the isolation room is taken as combustion air of the burning furnace and used for displacing toxic gas, so that the pollution is reduced.
Description
Technical field
The present invention relates to a kind of waste treatment equipment, particularly the one pig harmless treatment device of dying of illness.
Background technology
China is livestock culture big country, and cultivation scale is at the forefront in the world.In the process of livestock culture, because the reasons such as weather, epidemic disease exist certain death rate.For dead fowl poultry, need to carry out timely harmless treatment, avoid pestilence, environmental pollution even epidemic disease fowl poultry come into the market.The dead fowl poultry of traditional epidemic disease generally adopts method processing buried or that burn, adopts buried processing pollution abatement source completely; And employing burning disposal, because the moisture content of fowl poultry own is generally more than 60%, is burned moisture need to be evaporated completely completely, could completely organic and oil be burned, energy consumption is large, and the heat that burning produces also cannot utilize.And die of illness in pig processing procedure, the pig itself that not only dies of illness needs isolation processing to avoid epidemic disease to propagate, and the toxic gas producing after the pig long term exposure of dying of illness is also etiology.
Patent Office of the People's Republic of China's on October 18th, 2012 disclosed CN102921696A patent application document, name be called the pig treatment process of dying of illness, this technique comprises step 1, reception & disposal; The pig that dies of illness is collected and processed in place; Step 2, disinfect; Collecting the pig that dies of illness of processing in place, carry out disinfection; Step 3, sealing pulverization process; The pig that dies of illness after sterile-processed is delivered to airtight processing workshop, with cutting machine, the pig that dies of illness is cut off, then send in pulverizer, the crushing material cutting off; Step 4, boiling and squeezing processing; The material of pulverizing is sent to and in high-pressure bottle, carries out high-temperature sterilization and sterilizing; Step 5, fly maggot breeding; The slag of gained, as fly-maggot feed, carries out fly maggot breeding; Then separate, after separation, obtain residual thing, excreta and fresh maggot; Step 6, profit are further separated into You Heshui, and the oil obtaining, as biodiesel and industrial chemicals, carries out next step processing, and isolated water is sent in step 5 as fly maggot breeding is used after concentrated.In this process using thermophilic digestion process, need a large amount of energy to heat water, and water after heating is with the discharge of a large amount of heat, power consumption is large, and processing cost is high.And in above-mentioned technique, although die of illness, pig processing procedure adopts seal cavity processing, but seal cavity, especially shred the space of process, the long-term accumulated toxic gas that pig is distributed of dying of illness, the pig that can die of illness from confined space send into mouthful and overflow other positions, not only contaminated environment, cause the stink that is more far more than soot, and threaten operating personnel's health, and the toxic gas that is accumulated in for a long time confined space cannot process, and finally can only open confined space ventilative.
Summary of the invention
The object of the invention is to solve existing pig treating apparatus and the low problem of process heat utilization ratio of dying of illness, a kind of pig harmless treatment device of dying of illness of low power consuming is provided.Though another object of the present invention is to solve existing pig treating apparatus and the technique of dying of illness the pig itself that dies of illness is isolated, cannot process the problem of the toxic gas that the pig processing procedure of dying of illness distributes.
The technical solution adopted for the present invention to solve the technical problems is: the one pig harmless treatment device of dying of illness, comprise and provide the shredding machine of the combustion furnace of hot blast, chopping material and for stir-frying and carrying the cylinder of material after chopping, the discharging opening of shredding machine and combustion furnace air outlet connect the head end of cylinder, the end bottom of cylinder is provided with solid content outlet, the end of cylinder is also provided with exhaust outlet, exhaust outlet connects exhaust gas processing device, and the solid content outlet of cylinder end also connects the fuel inlet of combustion furnace by conveying device.The pig that will die of illness is chopped into after fritter, utilizes stir-frying of cylinder, has increased and the contact area of thermal current, and sterilization and drying effect are good, and make full use of heat.Compared with the mode of boiling, reduced the part thermal losses of heating water, improved heat utilization efficiency, and with respect to water boiling, thermal current can reach higher sterilization temperature.Cylinder is transported to solid content cylinder end in the process of stir-frying, in solid content, there is the flammable organic matters such as a large amount of greases, by conveying device, be transported to combustion furnace as fuel combustion, can realize and substituting completely or the loss of part alternative fuel, realize energy circulation, reduce the pig actual treatment cost of dying of illness.The tail gas of high temperature gas flow sterilization discharges after vent gas treatment.
