Stench can cause to seriously endanger as one of seven overall situation public hazards of the world to health and ecological environment, cultivation The gas of foul smelling taste is given out in can cause very big environmental problem, if a large amount of excrement is handled not in time, in height Foul gas, the people such as ammonia, the hydrogen sulfide of the lower generation that can ferment of temperature are harmful to by high-frequency, high intensity and long duration Will produce under the harm of gas cough, hypopnea, headache, Nausea and vomiting, have a stomach upset, anorexia, insomnia, eyes with And the symptoms such as nose and throat are stimulated, worried, depressed.In addition, ammonia also seriously affects the growth and development of live pig and healthy shape Condition, ammonia have an effect to respiratory center, influence the work of breathing of live pig by the olfactory nerves and trigeminal neuralgia of stimulation live pig Can, endanger the health of live pig.As a kind of public hazards, foul gas has caused the extensive concern of the whole society, country energetically Under the situation for promoting conservation culture development, the environmental pollution of animal husbandry primarily solves the problems, such as ecological safety.
The scheme of the foul smell of pig farm processing at present, generally physisorphtion, chemiadsorption, electrodecontamination method, ultraviolet light Deodorization and biological filter deodorizing etc., above method generally existing treatment effeciency is low, take up a large area and ammonia can not be again The problems such as recycling.
Utility model content
The utility model is low for existing pig farm Odor control efficiency, occupation of land is big and what ammonia can not recycle asks Topic, provides a kind of pig house deodorization device.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
A kind of pig house deodorization device, including adsorption tower and deodorizing tower, the adsorption tower side are connect with air blower, and inside is set There are vertical sulfuric acid wet curtain, sulfuric acid wet curtain upper end to be contacted with adsorption tower top inner wall, lower end is fixed by acidproof sieve, It is sulfuric acid holding tank below the acidproof sieve, sulfuric acid holding tank bottom end is exported equipped with recycle sulfuric acid, the absorption tower top End is equipped with recycle sulfuric acid entrance;The adsorption tower other side is connect with the deodorizing tower side bottom, and the deodorizing tower lower part is Gas mixing zone is followed successively by ventilation sieve, packing area, microbial inoculum area and spraying zone, the deodorizing tower on the gas mixing zone Top is equipped with gas outlet.
Further, the acidproof sieve is bolted on the sulfuric acid holding tank, and sulfuric acid holding tank side is set There is sulfuric acid adding mouth, sulfuric acid holding tank bottom end, which is equipped with, follows sour leakage fluid dram, and the sulfuric acid holding tank inner wall is detected equipped with acidity Meter.
Further, the deodorizing tower side bottom is equipped with waste liquid port, and the deodorizing tower bottom surface is to be tilted to the waste liquid port Inclined-plane, deodorizing tower top surface inner wall be equipped with humidifying spraying nozzle, the deodorizing tower side be equipped with insulating layer.
Further, the packing area is formed by bark and Chicken dung compost, and the microbial inoculum area is by fertile soil, vermiculite and EM Microbial inoculum is uniformly mixed.
The utility model has the beneficial effects that:The utility model is equipped with chemisorption and biological adsorption two systems, smelly Gas first passes through the sulfuric acid wet curtain circulatory system and absorbs part ammonia before entering biofilter, reduce the pressure of biofilter processing ammonia Power improves biofilter and adsorbs the efficiency of other pernicious gases, and reduces the floor space of biofilter, the ammonia in foul smell Gas may be used as agricultural fertilizer or industrial chemicals by becoming ammonium sulfate and ammonium hydrogen sulfate after adsorption tower after recycling processing.
