Multi-stage exhausting and deodorization device for livestock and poultry houses

Abstract

The invention discloses a multi-stage exhausting and deodorization device for livestock and poultry houses. The multi-stage exhausting and deodorization device comprises an exhaust outlet formed in a livestock and poultry house wall, an exhaust suction fan, an exhaust collection pipeline and a three-stage filtering device used in exhausting of waste gas from livestock and poultry houses; air is exhausted from the livestock and poultry houses by the fan in a negative-pressure manner; the deodorization device comprises a dust-barrier and flow guide module, a spray module and a biofiltering module, an underground drain outlet is connected below the spray module, a soil humidity sensor is arranged in the biofiltering module, and an automatic rainproof roller blind is arranged above the biofiltering module. The specific dimensions of the livestock and poultry houses can be calculated and designed according to the observed data of a proposed place, and are evaluated, not only can odor be effectively prevented from emitting to outside air and polluting air, but also the propagation of livestock and poultry diseases can be prevented while the exhausting and cleaning are achieved, and the multi-stage exhausting and deodorization device for livestock and poultry houses has higher economic benefits in the long run compared with the traditional exhausting and deodorization manner of the livestock and poultry houses.
