Description

Technical Field

[0001] The utility model relates to the technical field of poultry houses, and specifically relates to a linkage ventilation structure for ammonia in poultry houses. Background Art

[0002] A large amount of excrement is produced during poultry production. Once these nitrogenous excrement are discharged from the body, they are quickly decomposed into ammonia by the action of relevant enzymes and microorganisms in the feces. In large-scale farming, ammonia is a very important pollutant; poultry has a low tolerance to ammonia. my country's agricultural industry standards stipulate that the ammonia concentration in adult poultry houses should not exceed 15ppm; but in actual production processes, the ammonia concentration in poultry houses is much higher than this standard. In poorly managed poultry houses, the ammonia concentration can even reach 200ppm. It has been confirmed that ammonia concentrations of 25ppm are harmful to poultry.

[0003] At present, in order to reduce the ammonia concentration in the poultry house, the most effective method is to strengthen ventilation. In summer, due to the need for cooling, the fan is always on, the ventilation is good, and the ammonia concentration in the poultry house is relatively low; in winter, in order to prevent the temperature in the poultry house from dropping sharply, intermittent ventilation is generally used. However, the intermittent ventilation method of the poultry house is less effective in reducing the ammonia concentration in the poultry house, and it is difficult to control the ammonia concentration within the standard while maintaining the temperature of the poultry house. For this reason, a linkage ventilation structure of ammonia in a poultry house is provided. Utility Model Content
