Abstract
The utility model discloses a hog house heated by biogas. A fermentation bed is arranged below the hog house. A biogas digester is arranged below the fermentation bed. The fermentation bed is communicated with the hog house through a floor drain plate. A sewage draining outlet is arranged at the bottom of the fermentation bed. The sewage draining outlet of the fermentation bed is communicated with a feeding hole of the biogas digester through a sewage draining pipeline. A gas outlet of the biogas digester is connected with a gas storage tank. The gas storage tank is communicated with a boiler. A heating pipeline is arranged in the side wall of the hog house. The heating pipeline is communicated with the boiler. A reflux pipeline is arranged between the biogas digester and the fermentation bed. A pump is arranged on the reflux pipeline. The hog house heated by the biogas can reduce amount of labor used for clearing the hog house, effectively uses defecation objects such as pig manure, can reduce stink in the hog house due to the fact that the fermentation bed is arranged, and simultaneously facilitates growth of hogs due to the fact that organic materials generated by the fermentation bed can be used to feed the hogs. Furthermore, the biogas digester uses fermentation products of the fermentation bed to produce the biogas, and the gas storage tank collects the biogas, and accordingly the biogas is used for boiler combustion and heating the hog house through the heating pipeline.
