Abstract

The invention discloses an anti-backfire multi-nozzle burner and a waste gas treatment method. The combustor comprises a combustor body, the combustor body comprises a heat exchange cavity, and a first pipeline for introducing waste gas, a second pipeline for introducing fuel gas and a third pipeline for introducing combustion-supporting air are arranged at the bottom of the combustor body; the first pipeline is connected with a plurality of waste gas branch pipes, the waste gas branch pipes extend upwards to the top of the burner body, and waste gas burner nozzles are arranged at waste gas outlets of the waste gas branch pipes. The second pipeline is connected with a plurality of fuel gas branch pipes, the fuel gas branch pipes extend upwards to the top of the burner body, and burner nozzles are arranged at fuel gas outlets of the fuel gas branch pipes; a combustion-supporting air outlet used for sending out combustion-supporting air is formed in the top of the combustor body. According to the combustor, it is guaranteed that the temperature of flames is not transmitted to the waste gas amount, tempering is avoided, and a waste gas pipeline is not ignited.

Description

technical field [0001] The invention relates to the field of petrochemical waste gas purification, in particular to an anti-tempering multi-fire nozzle burner and a waste gas treatment method. Background technique [0002] Burners are a key part of gas / exhaust gas combustion devices, and are commonly found in various combustion-related industrial equipment, such as: direct-fired boilers, regenerative combustion devices, waste incinerators, and exhaust gas turbines. A burner with good performance can reasonably organize the mixing of fuel and oxidant (such as air), achieve safe and stable combustion, and ensure sufficient combustion efficiency and pollutant emission standards. For some special petrochemical plants, it is also necessary to meet the needs of flexible adjustment of flame length, combustion light-off temperature, heating temperature and heat load. According to the mixing method of gas fuel and air, it can be divided into three types, namely diffusion combustion,...
