A multi-swirl waste gas and liquid burner

Abstract

A multi-swirl exhaust gas and waste liquid burner of the present invention, a central air distribution cylinder and a plurality of side air distribution cylinders are arranged in the bellows, and the multiple side air distribution cylinders are evenly distributed on both sides of the central air distribution cylinder; the bellows A gas gun is installed in the inner central air distribution tube to spray the combustion-supporting gas required to maintain the incineration temperature; the end of the side air distribution tube is equipped with a waste liquid swirling flame stabilizer to generate a strong swirling combustion-supporting air to maintain the combustion air. Stable combustion. There is an exhaust gas gun in the side distribution duct for spraying waste gas to be treated, and a waste liquid gun for spraying waste liquid to be treated; the ignition gun adopts a secondary ignition method, first igniting the small fire of the ignition gun through high-voltage DC discharge, and then Then ignite the large fire in the burner through the small fire of the ignition gun; the flame detector is used to detect whether the small fire of the ignition gun is ignited successfully, and whether the large fire in the burner is within the safe range.

Description

technical field [0001] The invention relates to a multi-swirl waste gas and waste liquid burner, which belongs to the technical field of basic chemical combustion. Background technique [0002] Due to the long process flow and complex reaction process in the petrochemical industry, more pollutants such as waste gas and liquid that are difficult to handle or refractory environmental accumulations are produced during the production process, leaving many environmental problems. With the promulgation of environmental protection standards such as "GB 31570-2015 Pollutant Discharge Standard for Petroleum Refining Industry", "GB 31571-2015 Pollutant Discharge Standard for Petrochemical Industry", "Pollutant Control Standard for Hazardous Waste Incineration-Draft for Comment" and Implementation, the requirements for reducing nitrogen oxides, particulate matter emissions and incineration removal rate in flue gas are becoming more and more stringent. [0003] The waste liquid at the ...

AI Technical Summary

Problems solved by technology

[0003] The waste liquid at the bottom of the chemical tank after many reaction processes contains a small amount of solid impurities and a large amount of heavy components, has a high boiling point, high viscosity, heavy density, complex physical properties and a large variety. Due to technical challenges, problems such as insufficient atomization of waste liquid, poor turbulent flow intensity, and uneven distribution of flow field and temperature field often occur, resulting in the incomplete decomposition of waste liquid and the generation of more particulate matter, nitrogen oxides, and non-methane total hydrocarbons, which cannot meet the standards emission
