Description
Technical field
The utility model belongs to a kind of gas collection equipment, particularly relates to a kind of ammonia decontamination for breeding house and gathering unit.
Background technology
Along with developing rapidly of China's livestock breeding, animal farm scale, intensive and mechanization degree improve gradually, and herding village, breeding scale house but usually occur environment difficulties.The air pollution of livestock and poultry farm mainly come from distribute in plant have taste gas, the pernicious gases such as a large amount of ammonias can be produced after feces of livestock and poultry and sewage fermentation, cause ammonia emission amount rising in unit are in breeding house, ammonia not only easily causes Animal stress, greatly affect growth rate and the feedstuff-meat ratio of livestock and poultry, and severe contamination environment, be grow mosquitos and flies, bacterial reproduction and pathophorous source of infection, harm livestock birds health, affects the mankind and produces normally and live.Especially at the winter-spring season of very cold, in order to improve the heat insulation effect of livestock and poultry cultivation house, door and window is closed to reduce ventilation by most raiser, ammonia level in livestock and poultry cultivation house can be higher, had a strong impact on the normal growth of livestock and poultry, caused the economic loss of raiser, and once arbitrarily exhaust ventilation, temperature Change in house can be made excessive, easily cause livestock and poultry cold, also result in the waste of the heating and thermal insulation energy simultaneously.
Ammonia in livestock and poultry cultivation house air mainly, bacterium corrupt from organic matters such as livestock and poultry gastrointestinal disturbances, fecaluria, food-residue and pad grass decomposes body waste and produces, a kind of colourless, poisonous, gas with intense stimulus stink, can feel that least concentration is 5.3ppm, moist at bedding and padding, when acid-base value is suitable for, temperature is high, ight soil is many, ammonia produces faster.In poultry house, the content of ammonia depends on that the dirt of stocking density, ventilation situation, earth construction, feeding and management level, excrement is removed.The aqueous solution of ammonia is in alkalescence, irritant to mucous membrane, alkali burn can occur time serious, can cause that eyes are shed tears, cusalgia, Cornea and conjunctiva inflammation, dysopia.Ammonia enter respiratory tract can cause cough, tracheitis, bronchitis, pulmonary edema hemorrhage, have difficulty in breathing, suffocate.Ammonia has reproducibility, hydrogen atom in its molecule can be replaced one by one by metal, generate metal amide or nitride, therefore, ammonia enters blood by alveolar, can be combined with haemoglobin, makes ferroheme become hematin, reduce the oxygen carrying capacity of haemoglobin, the storage of blood alkali and the oxidation susceptibility of ferroheme, thus occur anaemia and histanoxia.Ammonia is generally acknowledged stressor, be gas the most harmful in poultry house, ammonia can induce the generation of the animal such as poultry, pig various respiratory tract disease, can induce or improve the incidence of disease of dorking abdominal dropsy, under 10-15mg/kg ammonia density, the resistance of animals against infection can be reduced.According to surveying and determination, when in hen house, the concentration of ammonia reaches 20mg/L, the incidence of disease of all kinds of common disease, frequently-occurring disease can improve suddenly, when concentration rises to 50mg/L, the respiratory rate of chicken can be made to slow down, and therefore the egg production of laying hen can reduce, and chick weight gains and efficiency of feed utilization decline to a great extent.The poultry-farm of 560,000 scales, the ammonia can discharging 10.5kg per hour, produces the piggery of 80,000 pigs per year for one, per hourly reaches more than 130kg to airborne release ammonia, and too much ammonia emission not only causes the waste of a large amount of feed resource, and add environmental pressure.
For this reason, people control to have carried out following research to reducing ammonia level in livestock and poultry cultivation house, research one: by the intake of protein in conservative control livestock and poultry diet, reduce amino acid under the catalytic action of putrefactive microorganisms urase, uricase, be hydrolyzed the amount generating ammonia, in feed, add the generation that the silicates such as zeolite powder, bentonite, fermentable carbohydrates, enzyme preparation, plant extracts etc. reduce ammonia simultaneously; Research two: reduce the pH value in ight soil, in dropping-board or manure pit, spreading ferrous sulfate suppresses the fermentation Sum decomposition of ight soil, or adds active bacteria formulation, thus effectively reduces the concentration of ammonia; Research three: by increasing livestock and poultry cultivation house height, installs the antibacterial method such as ammonia system, ammonium sulfate recovery system that presses down of micro-electric current to reduce the ammonia in livestock and poultry cultivation house.
Although these achievements in research serve certain effect to the livestock and poultry cultivation house elimination of ammonia and purification, itself or complicated operation, or invest excessive, energy ezpenditure is too much, is unfavorable for applying in vast livestock and poultry cultivation house.In existing livestock and poultry cultivation house, mostly still utilize ammonia density to be less than air, be distributed in livestock and poultry cultivation house top, feature soluble in water, by collecting and ammonia removal for the ammonia decontamination of breeding house and gathering unit, the most complex structure of the existing device for collecting ammonia gas for breeding house, is not easy operation, and the water circulation system of collecting ammonia is poor, have a strong impact on the collecting effect of ammonia, the requirement of low ammonia level in modern livestock and poultry cultivation house cannot have been reached.
