Methane automatic burning heat energy recovering blind fire torch

Abstract

The invention belongs to the technical field of methane treatment equipment and relates to heat energy recovering equipment, in particular to a methane automatic burning heat energy recovering blind fire torch. The methane automatic burning heat energy recovering blind fire torch comprises a torch cylinder body, a heat exchange inner cavity is formed in the middle of the interior of the torch cylinder body, a heat exchange coiled tube is arranged in the heat exchange inner cavity, and the water inlet end of the heat exchange coiled tube is connected with a heat exchange water inlet tube; a methane inlet tube is arranged at the bottom of the torch cylinder body, the gas inlet end of the methane inlet tube extends out of the torch cylinder body and is connected with a methane air source, and the gas outlet end of the methane inlet tube extends to the center position of the bottom of the torch cylinder body; and the gas outlet end of the methane inlet tube is connected with a plurality of burning heads through a plurality of branched gas tubes. According to the methane automatic burning heat energy recovering blind fire torch, methane generated in the sewage treatment technique can be recycled, heat energy generated through methane burning is utilized to increase the temperature of a sewage treatment anaerobic pool, thus efficiency of anaerobic degradation is improved, and energy saving and environmental friendliness are achieved; through the multiple burning heads uniformly distributed in a multi-layer mode, the flow speed of the methane of outlets of the burning heads can be decreased; and a fire barrier can prevent backfire.

Description

technical field [0001] The invention relates to heat energy recovery equipment, in particular to a dark fire torch for automatic combustion of biogas to recover heat energy, and belongs to the technical field of biogas treatment equipment. Background technique [0002] In the biochemical sewage treatment process, anaerobic treatment will produce a large amount of biogas, usually under anaerobic conditions, the degradation of 1kgCOD will produce about 0.42-0.45Nm3 biogas, the methane content is about 60%, and its calorific value is 21.52×103kJ / m3 about. The direct discharge of biogas will aggravate the greenhouse effect and waste energy. With the increasing environmental protection requirements, the comprehensive treatment of biogas has become an increasingly urgent demand. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a kind of biogas automatic combustion heat energy recovery dark fire tor...
