Background technology
The main sub product of livestock and poultry farms in scale, sewage work, Residential areas: ight soil, mud and organic waste (being referred to as organic waste or fermentation raw material); Big and the high concentration of amount; If can not timely and effectively dispose, very easily cause serious environmental to pollute.Aerobic fermentation (compost) can make organic waste realize minimizing, innoxious, recycling treatment through the microbiological deterioration organism.The place compost fermentation technology that extensively adopts at present, the main existence: 1. floor space is big; 2. fermentation time is grown (the general one time fermentation time needs about 15~30 days); 3. degradation problem under the fermenting speed when microthermal climate.Most research at present is efficient or the effect that improves aerobic compost through the means such as forcing oxygen therapy, turning or stirring of ventilating, and heat and foul smell that fermentation produces then generally let alone to be discharged into atmosphere, have caused great environmental pollution; And famous Da Nuo (Dano) drum-type aerobic reactor; Relatively the place fermentation has characteristics such as fermentation efficiency height, occupied ground area are little; But ferment effect depends on factors such as drum length, for prolonging the residence time of fermentation raw material in the cylinder reactor drum such as organic waste guaranteeing ferment effect, the length of cylinder be usually designed to diameter of cylinder more than 10 in addition reach more than 20 times; Therefore floor space is still very big; Device fabrication is with high costs, also exists the material (organic waste) that newly advances too small with the fermentation materials contact area simultaneously, newly advances material shortage sufficient fermentation starter thereby speed of response and waits shortcoming more slowly.Therefore, the research and development floor space is littler, fermentation efficiency is higher, not influenced by winter low temperature, do not produce secondary pollution, and the minimizing of organic waste Rapid Realization, treatment technology and high-efficiency aerobic reactive system innoxious, resource utilization are very important.
Summary of the invention
The utility model technical problem to be solved is: solve the problem that above-mentioned prior art exists; And a kind of air inlet system and exhaust system that are used for aerobic fermentation reaction are provided; Effectively resolve in the aerobe fermentation process a large amount of foul smell, heat effluxes problem of environment pollution caused, the protection environment reclaims heat energy; Stablize the fermentation reaction temperature, reduce the air-supply energy consumption.
The technical scheme that the utility model adopts is: this air inlet system and exhaust system that are used for the aerobic fermentation reaction; Comprise aerobic fermentation reactor drum, blower fan, pipeline; The gas exhaust duct of aerobic fermentation reactor drum connects the exhaust air deodorization treatment facility, and perhaps the vapor pipe of aerobic fermentation reactor drum connects the exhaust air deodorization treatment facility through vacuum fan.
In the technique scheme, the power of the air inlet system and exhaust system of aerobic fermentation reactor drum is a vacuum fan, and the inlet pipe of vacuum fan links to each other with the vapor pipe of aerobic fermentation reactor drum, and the vapor pipe of vacuum fan connects the exhaust air deodorization treatment facility through ventilator trunk.
In the technique scheme; The power of intake and exhaust is a vacuum fan and a gas blower; The inlet pipe of vacuum fan links to each other with the vapor pipe of aerobic fermentation reactor drum; The vapor pipe of vacuum fan connects the exhaust air deodorization treatment facility through ventilator trunk, and the venting port of gas blower links to each other with the inlet mouth of aerobic fermentation reactor drum, and the inlet mouth of gas blower is connected to atmosphere.
In the technique scheme, the inlet pipe of aerobic fermentation reactor drum is provided with air heating apparatus.
In the technique scheme, be provided with material oxygen level transmitter and temperature of charge transmitter in the aerobic fermentation reactor drum, material oxygen level transmitter and temperature of charge transmitter are connected to system respectively.
In the technique scheme; Said system detects the size of oxygen level in the aerobic fermentation reactor drum and the temperature of fermentation raw material; When detecting oxygen level and surpass set(ting)value less than set(ting)value or temperature; The output speed of the startup of wind turbine or increasing blower fan in the system control air inlet system and exhaust system, guaranteeing provides appropriate enough fresh airs to the aerobic fermentation reaction.
The beneficial effect of the utility model is: the reaction foul smell is through discharging again after focusing on, and makes gas such as ammonia nitrogen obtain recycling rather than be discharged into the topsoil environment; Air intake helps the stopping reaction temperature through the interchanger heating; The additional of oxygen is to carry out closed-loop control according to the oxygen level of waste gas, the minimizing of maximum amplitude energy consumption and the high air output of air-supply to the influence of leavening temperature.
