Biogas automatic grading burner

Abstract

The invention belongs to the technical field of tail gas treatment in the methane industry, and provides a burner capable of achieving automatic staged burning of methane at different pressures. The burner can achieve thorough burning and is safe and environment-friendly. The burner adopts the technical scheme that a main burner nozzle is mounted at the upper end of a main blow-down pipe; a main burner nozzle spoiler is mounted at the upper part of the main burner nozzle; a central pipe with an opened upper part and a opened lower part is fixedly mounted at the middle part of the main burner nozzle in a sleeving manner; a methane distribution chamber is mounted on the external circumference surface of the central pipe in a sleeving manner; a plurality of secondary burner nozzles are mounted on the methane distribution chamber; the methane distribution chamber is communicated with the main blow-down pipe by a plurality of distribution pipes; a plurality of primary gravity pressure regulation devices are mounted at communicating openings; a burner air mixer is mounted above the methane distribution chamber; a plurality of venturi air inlets are formed in the burner air mixer; the methane distribution chamber is divided into a plurality of cavities from the top down by partition plates; every two adjacent cavities are mutually communicated; a plurality of gravity pressure regulation devices are mounted at communicating openings; and the secondary burner nozzles are mounted on the cavities.

Description

technical field [0001] The biogas automatic grading burner of the invention belongs to the technical field of tail gas treatment in the biogas industry. Background technique [0002] Biogas is a kind of clean energy, but it is also a kind of harmful gas, which can easily cause danger if used improperly. Methane, the main component of biogas, is an important greenhouse gas second only to Freon, which can destroy the ozone layer of the atmosphere. According to the research report of the Transnational Commission on Climate Change, its greenhouse effect is 21 times that of carbon dioxide. With the adjustment of my country's energy structure and the increasingly stringent emission regulations, there are countless applications of existing biogas power generation projects. However, in the process, a certain amount of biogas will be released whether it is early commissioning or later maintenance, which will cause adverse effects on the environment. .
