Pigpen heating system with feces as fuel

Abstract

The invention discloses a pigpen heating system with feces as a fuel. A gas burner is installed at the front portion of a combustion chamber, the rear portion of the combustion chamber is connected with a flue gas inlet of a heat exchanger, a cold air inlet of the heat exchanger is connected with an outlet of a circulating fan, an inlet of the circulating fan is connected with an outlet of a return air duct, the return air duct is communicated with a return air hood, a hot air outlet of the heat exchanger is connected with an air supply duct, the air supply duct is connected to an air supply hood, the air supply hood and the air return hood are both installed in a pigpen, the gas burner is connected to a gas outlet of a gasifier, a horizontal air tube is disposed in an inner cavity of thelower portion of the gasifier, a gap for ash discharge is formed in an air tube, a plurality of through holes are formed in the lower portion of the air tube, and both ends of the air tube are connected to an air collecting box; the system has the advantages of being clean and environmentally friendly, and can achieve the energy regeneration, harmlessness and resource utilization of the feces.

Description

technical field [0001] The invention belongs to the technical field of waste treatment, and in particular relates to a pig house warming system using manure as fuel. Background technique [0002] With the rapid development of China's animal husbandry, the discharge of livestock and poultry manure caused by livestock and poultry production is increasing, which seriously affects the sustainable development of China's agriculture. The large increase in the discharge of livestock and poultry manure has brought heavy pressure on the rural ecological environment and seriously affected the sustainable development of China's agriculture. In traditional production methods, farmers collect livestock and poultry manure and return it to the fields, thereby reducing pollution to adjacent water resources and the atmosphere. However, since the "Green Revolution" in the 1960s, traditional organic fertilizers have been replaced by chemical fertilizers to a large extent, and a large amount o...
