The disinfection and deodorization spray equipment of the breeding farm is a new type of purification and deodorization device that uses fog to control air. Its principle is to use a high-pressure pump to pressurize the mixed deodorant or disinfectant to more than 50 kg, through the high-pressure pipeline, to the high-pressure nozzle for atomization, forming a flying water mist, creating good and fresh ambient air. The rapid vaporization of fog particles and adsorption and decomposition of pollution factors can achieve multiple effects such as deodorization, disinfection, dust removal, cooling, and can remove trace solid dust in the air and increase air humidity; The system has low cost, good operating effect, and can achieve unmanned automatic control.
