Embodiment
[0021] 1. Litter broiler house:
[0022] The absorber 1 is installed on the high-pressure polyethylene porous pipe 2, the high-pressure polyethylene porous pipe 2 is bound together with the main pipeline of the litter broiler house feeding system, and one end of the total gas pipeline 3 is connected with the high-pressure polyethylene porous pipe 2 , the other end is connected with the variable frequency fan 4 outside the house, and the length of the vacuum tube installed between the high-pressure polyethylene porous pipe 2 and the ceiling in the house is scalable and adjustable. In this way, as the chickens grow and the bedding in the house is added or removed, the feeding system must be continuously raised or lowered to ensure that the entire gas collection system can also be adjusted up and down. Turn on the frequency conversion fan to extract air, and the high-concentration pollutant gas on the manure surface of the broiler house will be directly extracted and transported ...

The invention discloses an indoor air quality control method and system for a henhouse. A plurality of high-pressure polyethylene perforated pipes are mounted on the surface of feces in the henhouse, absorbers which are arranged at equal intervals or unequal intervals are arranged on each high-pressure polyethylene perforated pipe, the plurality of high-pressure polyethylene perforated pipes are connected with one end of a frequency conversion fan outside the henhouse via a main gas pipeline, and the other end of the frequency conversion fan is respectively connected with an odor removing device and a fresh air source through electromagnetic valves. When in air extraction, high-concentration polluted gas in the henhouse can be directly extracted and transmitted to the outside of the henhouse; when in air supply, fresh air outside the henhouse can be conveyed into the henhouse for local air exchange. The method and the system can not be affected by a ventilation system in the henhouse, and the system has two functions of collecting the harmful gas and conveying the fresh air, and can not only improve the air quality of a living region for chicken in the henhouse, but also be conductive to follow-up centralized treatment outside the henhouse, thus the discharge of gas pollutants is reduced. The method and the system are applicable to the henhouses adopting mechanical ventilation and natural ventilation.
Description
technical field [0001] The invention relates to an air quality control method and system, in particular to a method and system for controlling the indoor air quality of a chicken coop. Background technique [0002] The gaseous pollutants in the chicken house mainly come from the feces excreted by chickens, the use of litter and wasted feed and other wastes such as malodorous gases generated by decomposition. In the malodorous odor, it mainly includes nitrogen compounds (ammonia, methylamine), sulfides (hydrogen sulfide, methyl mercaptan), aliphatic compounds (indole, acrolein, and skatole, etc.), carbon dioxide, and methane gas. These malodorous substances, especially ammonia, hydrogen sulfide and other gases are easily soluble in water. Therefore, they can be absorbed by the mucous membranes and conjunctiva of humans and animals, causing congestion, edema and even inflammation of the conjunctiva and mucous membranes of the respiratory system. Central paralysis and death; i...
