A livestock breeding shed exhaust purification device and method

Abstract

The invention discloses an exhaust gas purification device and method of a livestock breeding shed, belonging to the field of breeding equipment. The device includes: a collector, an air duct, a blower, an air cleaning device and a driving device; the collector includes a connecting plate, two upper baffles located on both sides of the connecting plate and a deflector located below the upper baffle; the collector has at least It has a first working state and a second working state: when it is in the first working state, the two upper baffles and the two deflectors are arranged in a figure-eight shape, and the lower edge of the upper baffle is against the top of the deflector. Surface; when in the second working state, the deflectors are arranged vertically, and the two deflectors are arranged in an inverted figure-eight shape; one end of the air guide tube is connected to the air purifier, and the other end is connected to the connecting plate. The invention only needs to rotate the deflector to make the collector in the second working state to discharge the dirt, and the dirt will be concentrated in the middle part of the dung storage tank, which can prevent the harmful gas from flowing back into the breeding shed.

Description

technical field [0001] The invention relates to the field of breeding equipment, in particular to an exhaust gas purification device and method for livestock breeding sheds. Background technique [0002] In recent years, the scale of livestock and poultry breeding has gradually increased; in large-scale livestock and poultry breeding, there are three main treatment processes for livestock and poultry manure: dry manure cleaning, water flushing manure and water soaking manure. In comparison, the dry manure cleaning process consumes a lot of manpower and high labor costs; the water flushing manure process requires a lot of water and wastes water resources; therefore, the water soaking manure process is adopted by most large-scale breeding sites. Blister manure cleaning process is improved on the basis of water flushing manure process. The technological process is to inject water into the livestock and poultry house, and the water flow washes the excrement of livestock and poul...
