Description

Technical Field

[0001] The invention relates to a novel deodorizing mesh filter screen mold structure, in particular to a special mold structure for producing a novel deodorizing mesh filter screen, and belongs to the field of environmental protection technology and equipment in animal husbandry. Background Art

[0002] With the large-scale development of livestock and poultry farming, the feces in livestock and poultry houses will produce a large amount of malodorous gases. In order to keep the air in livestock and poultry houses fresh, the current method is to use exhaust fans to forcefully discharge the malodorous gases in livestock and poultry houses outside the houses. The malodorous gases in livestock and poultry houses mainly include ammonia, hydrogen sulfide, volatile fatty acids, skatole, alcohols, etc. Among these malodorous substances, ammonia (NH 3 ) and hydrogen sulfide (H 2 S), ammonia and hydrogen sulfide are the decomposition products of nitrogen-containing organic matter and sulfur-containing organic matter in feed and feces respectively; ammonia (NH 3 ) and hydrogen sulfide (H 2 S) are toxic, irritating, narcotic or asphyxiating, and can cause death in severe cases. Directly discharging the malodorous gases from livestock and poultry houses outdoors without any treatment will greatly pollute the atmospheric environment and cause serious pollution to nearby residents and crops. The malodorous gases from livestock and poultry houses need to be deodorized before being discharged outdoors. At present, physical and chemical methods are mainly used in my country's industry to treat malodorous gases, such as combustion, adsorption, absorption and oxidation-reduction. The processes and equipment of these methods are relatively complex and the operating costs are high. Especially when used for malodorous waste gases discharged from livestock and poultry farms, the effect is not ideal.

[0003] In order to solve the industry problem of deodorization of malodorous gases generated in livestock and poultry houses, the inventors have attempted to design a new deodorization grid filter mold structure and professionally produce a new deodorization grid filter. A number of grid filters are stacked together to form a grid-shaped deodorization wall, and a liquid medicine spray pipe is provided on the top of the deodorization wall to form a spray water curtain wall to filter, absorb and decompose the malodorous gases for harmless treatment. This treatment method is simple, with low investment in deodorization technology, low energy consumption and low operating costs. The low-cost livestock and poultry house odor deodorization filter wall is used, and the gas after the odor is filtered by the filter wall is odorless and harmless gas that meets the national standards, which fundamentally solves the safety problem of malodorous gas deodorization emission in livestock and poultry houses and promotes the healthy development of the livestock and poultry breeding industry.
