Biogas heating and ventilating system for hog house

Abstract

The invention relates to a biogas heating and ventilating system for a hog house. The biogas heating and ventilating system comprises hog houses, a methane tank, a combustion furnace, a heat exchanger and a control apparatus, A passage is connected between the two rows of the hog houses, a plurality of air exhausting ports are arranged in the outer wall of the two rows of the hog houses, and a plurality of air inlets are arranged in the interior wall of the two rows of the hog houses. The methane tank is connected with feces pools on the bottoms of the hog houses through defecation pipes, the combustion furnace is connected with the methane tank through a biogas pipe, and the combustion furnace is connected with a combustion-supporting blower fan through a combustion-supporting pipe. A combustion-supporting blower fan is connected with the air exhausting ports in the hog houses through aspiration pipes, the combustion furnace is connected with a heat exchanger through a hot air pipe, and the heat exchanger is connected with the air inlet blower fan through an air inlet pipe. The heat exchanger is connected with the air inlets in the hog houses through air-supply pipes, and the control apparatus is connected with the blower fan, the methane tank and the combustion furnace through leads. The biogas heating and ventilating system has diversified functions, is environmental-friendly, reduces energy consumption, and is applicable to large culturing farms.

Description

technical field [0001] The invention relates to the technical field of pig breeding, in particular to a biogas heating and ventilation system for pig houses. Background technique [0002] The traditional way of raising pigs is decentralized and simple captive breeding. This kind of pig house is too simple. In the cold winter, it is easy to cause some pigs to be unable to resist the low temperature, consume feed and not grow meat, and some even freeze to death, which makes the development cost higher. , the risk increases. With the development of the breeding industry, heating structures have been added to the existing pig houses. Now the government has given a large amount of economic subsidies to the farms to support the construction of large-scale biogas digesters, which not only solves the environmental protection problems of pig house manure discharge, but also produces biogas The biogas provided by the pond becomes a kind of energy, which can heat the pig house.

With the development of the breeding industry, heating structures have been added to the existing pig houses. Now the government has given a large amount of economic subsidies to the farms to support the construction of large-scale biogas digesters, which not only solves the environmental protection problems of pig house manure discharge, but also produces biogas The biogas provided by the pond becomes a kind of energy, which can heat the pig house. During the breeding process, a large amount of pig manure will be produced in the pig house, and the air quality in the pig house is not high. Do not ventilate in time to ensure the air quality. The advanced biogas heating system cannot timely ventilate the pig house while heating. Ventilation will take the heat out of the pig house. In order to maintain the pig house, it will cause waste of energy consumption.
