Description:
TECHNICAL FIELD 
       [0001]    The invention relates to a method for treating pollutants, and specifically to a method for anaerobic pyrolysis treatment of dead-of-disease livestock and municipal organic refuse. 
         [0002]    The invention also relates to a device for realizing the above-mentioned method. 
       BACKGROUND ART 
       [0003]    Chinese economic reform and economic development proceed, the animal husbandry in our country has been rapidly developed, and the “shopping baskets” of residents have been greatly improved and the living standard of people has been increased. The animal husbandry in our country excellently contributes to agriculture and domestic economy: in 2010, the production of meats is 79.25 million tons and has been in the first place in the world for 21 years; the production of poultry eggs is 27.65 million tons and has been in the first place in the world for 26 years; and the production of milks is 37.80 million tons and is in the third place in the world. With rapid development of animal husbandry, the environment of urban areas and the ecological environment of rural areas encounter great stress, and the pollution caused by the livestock and poultry breeding is more and more severe. Therefore, it has been a significant and urgent task for rural environmental protection to enhance pollution control and environmental management of livestock and poultry breeding. 
         [0004]    By taking Jiaxing city, Zhejiang province as an example, Jiaxing city lies in the center of Changjiang River Delta, and is near to Suzhou, Hangzhou, Shanghai, on the north, the south, and the east, respectively. Pig breeding has been developed since early 1990s, and nearby markets are mainly supplied. As a conventional intensive pig breeding region, the number of pig breeding units in the entire Jiaxing city has exceeded 100 thousand, and the number of fully grown pigs per year is 4.5 million. Under the conditions of extensive and intensive feeding, high death rate of pigs is unavoidable. In general, the death rate of adult sows per year is up to 2%-3%, the death rate of middle-age pigs is up to 7%-8%, and the death rate of piglets is even higher. According to local reports of special topics by CCTV, the average total death rate, from the time when a piglet is born to the time when it is fully grown, is 10%. Based on the calculation according to the data described above, the number of dead pigs for various reasons in Jiaxing area per year is up to hundreds of thousands. A large number of dead-of-disease livestock are not subjected to harmlessness treatment every year and some are even discarded into rivers, which does not only severely pollute the environment but also propagates fatal animal diseases, such as foot-and-mouth disease, highly pathogenic avian influenza, highly pathogenic blue-ear pig disease, and swine fever. 
         [0005]    Municipal domestic refuse is solid waste produced in human life. In the process of collection, transportation and treatment, harmful components contained in and produced from the refuse will pollute the atmosphere, the soil, bodies of water. This does not only severely affect the quality of the municipal environment but also threatens health of people, and thus it becomes one of social public hazards. The annual production of municipal refuse per capita in China is up to 440 kilograms. In 1996, the amount of cleaned and transported municipal domestic refuse in China is up to 100 million tons, and increases at a rate of 8% to 10% per year. The amount of stockpiled municipal refuse in past years is up to 6 billion tons, and more than 200 cities in the whole country are surrounded by refuse. The stockpiled refuse occupies a land area of up to 500 million square meters. How to solve the problem of municipal refuse to provide a healthy and clean living environment to urban and rural residents has been highly focused in the whole society. 
         [0006]    At present, organic refuse, such as dead-of-disease livestock and municipal refuse, are treated by incineration in many places. The process of incineration treatment does not only generate hydrogen sulfide (odor) which pollutes air, but also emits a number of toxic and harmful substances such as dioxin, nitrogen oxides, and sulfur dioxide, which affect health of residents nearby. The main reason why the above organic refuse such as dead-of-disease livestock and municipal refuse generates toxic and harmful substances, such as hydrogen sulfide (odor), dioxin, nitrogen oxides and sulfur dioxide, is the pyrolysis (combustion) treatment performed in an aerobic state. In dead-of-disease livestock and municipal refuse, ammonia nitrogen generates nitrogen oxides by the pyrolysis (combustion) in an aerobic state; sulfur generates sulfur dioxide by the pyrolysis (combustion) in an aerobic state; chloride ions generate dioxin by the pyrolysis (combustion) in an aerobic state; and carbon generates carbon dioxide and the like by the pyrolysis (combustion) in an aerobic state. 
         [0007]    An anaerobic pyrolysis method and device for pyrolyzing organic refuse such as dead-of-disease livestock and municipal refuse in an anaerobic state, so as to solve the problems of reutilization and harmlessness treatment of organic refuse such as dead-of-disease livestock and municipal refuse generated during production and living of human beings and to prevent the generation of toxic and harmful substances such as hydrogen sulfide (odor), dioxin, nitrogen oxides and sulfur dioxide, has not been reported so far.

       EXAMPLE 
     Anaerobic Pyrolysis Treatment of Dead-of-Disease Pigs 
       [0067]    When the anaerobic pyrolysis device began to operate, bodies of dead-of-disease pigs, after being treated by a crusher, were conveyed to the anaerobic pyrolysis chamber  20  through the screw conveyor  37  and the conveying pipeline  12  of the anaerobic pyrolysis device. As viewed from one end of the anaerobic pyrolysis chamber  20 , the anaerobic pyrolysis chamber  20  rotated at 1-3 rotations per minute in the clockwise direction. The combustor  47  began to work (the fuel of the combustor may be natural gas, coal gas, or uncondensed combustible gases), and the temperature of the combustion chamber began to increase. When the temperature of the combustion chamber was increased to 300-500° C., the vaporization and pyrolysis reaction of tissues of bodies of dead-of-disease pigs began at this high temperature, to generate a gas composed of steam, hydrogen, methane, ethane, carbon monoxide, etc. The generated gas was conveyed through the gas discharge pipe  38  and the gas discharge port  39  to the spray column  48  for performing a cleaning and separation treatment, such that steam in the gas was condensed into condensed water, and remaining uncondensed combustible gases were conveyed to the combustor  47  through the coal gas discharge and feed fan  53 , to be recovered and reutilized as fuel of the anaerobic pyrolysis device. 
         [0068]    When the temperature of the combustion chamber was increased to 500-600° C., reactions such as dehydrogenation, thermal condensation, and carbonization were accomplished, to convert the tissues of bodies of dead-of-disease pigs to organic carbon. The organic carbon was continuously heated to 750-900° C., and activated steam was delivered through the external steam pipe  27 , the rotatable joint  28 , the connecting hose  31 , and the activated steam conveying pipe  33  to the anaerobic pyrolysis chamber  20 , where it carried out an activation reaction with the organic carbon to perform an activation treatment on the organic carbon. The activated organic carbon after activation may be used as a water-treating material and a soil amendment. 
         [0069]    After activation, as viewed from one end of the anaerobic pyrolysis chamber  20 , the anaerobic pyrolysis chamber  20  rotated at 1-3 rotations per minute in the counterclockwise direction. The activated organic carbon was passed into the cooling device  49  via the discharge plate  14  in the anaerobic pyrolysis chamber  20 , the conveying pipeline  12 , the spiral plate  4 , the discharge pipe  5 , and the discharge port  6 . 
         [0070]    In the operation process of the anaerobic pyrolysis device, when the temperature was excessively high, or the oxygen content was excessively high, or the concentration of combustible gases was excessively high in the isolation room  1 , steam was input to the isolation room  1  through the steam input pipe  45 , to lower the temperature, the concentration of combustible gases, or the oxygen content in the isolation room  1 . 
         [0071]    In the operation process of the anaerobic pyrolysis device, bio-oil in the isolation room  1  was discharged from the bio-oil discharge port  40  at the bottom and flowed into oil storage tank  50 . 
         [0072]    In the operation process of the anaerobic pyrolysis device, the wireless temperature sensor  29 , the temperature sensor  41 , the pressure sensor  42 , the combustible gas sensor  43 , the oxygen content sensor  44 , etc., transmitted parameters such as temperature, pressure, combustible gas, oxygen content at respective sites of the anaerobic pyrolysis device to electrical control cabin  54  respectively, and the anaerobic pyrolysis device was safely operated under the control of the electrical control cabin  54 .
