Description
Technical field
The present invention relates to technical field of air purification, more particularly to a breeding house inner air-cleaning device.
Background technique
The approach that harmful gas in livestock house (ammonia, hydrogen sulfide, carbon monoxide and carbon dioxide) generates mainly has: first is that
Livestock and poultry organism metabolism generates, and the carbon dioxide that livestock and poultry respiratory metabolism generates is the main source of poultry house carbon dioxide: second is that big
The protein that do not digest and assimilate is measured to excrete by gastrointestinal tract.Harmful gas such as ammonia, hydrogen sulfide is generated by microorganism decomposition
Body: third is that the uric acid that metabolism generates is converted into allantoin under the action of urase, allantoin be further broken into glyoxylate and
Urea.Urea is converted into ammonia and carbon dioxide under the action of urease: fourth is that the feed being scattered during Production of Livestock and Poultry is residual
Slag and padding undergo microbial fermentation generation.
Ammonia is a kind of colourless gas soluble easily in water, and hydrogen sulfide is colourless rotten-egg odour.The ammonia of high concentration in poultry house
Gas, hydrogen sulfide will affect breeding performonce fo animals, destroy respiratory mucosa, increase the generation of respiratory disease, reduce immunity, draw
It plays Ascites Disease and increases animal suffering from disease risk, seriously affect animal welfare.By taking chicken as an example, a large number of studies show that.It is highly concentrated in henhouse
Degree ammonia can reduce broiler chicken feed intake, reduce daily gain, increase feed-weight ratio, increase risk.The ammonia of high concentration, which has, to lure
Send out the trend that broiler chicken liver ascites occurs.Ammonia not only influences livestock and poultry production performance and has an effect on animal and bird intestines health.The ammonia of high concentration
Gas can make tracheal mucosa atrophy degenerate, and mucilage secretion increases, and Pulmonary Vascular is congested and blutpunkte occurs, and broiler chicken is caused to generate oxidation
It stress be with immunological stress；Hydrogen sulfide can reduce broiler chicken feed intake, daily gain, reduce feed efficiency, keep tracheal mucosa glutinous
Liquid secretion increases, and increases the rupture of cilium damage rate and alveolar, reduces immunity, and lead to the generation of meat of poor quality.The prior art
The fixation that means realize the pernicious gases such as foul smell is adsorbed by active carbon etc., the later period can generate a large amount of absorption by-products, after causing
Continuous processing cost increases and treatment effect is poor.
