Multi-cyclone waste gas and liquid combustor

Abstract

The invention discloses a multi-cyclone waste gas and liquid combustor. A central air distribution cylinder and a plurality of side air distribution cylinders are arranged in an air box, and the sideair distribution cylinders are uniformly distributed on the two sides of the central air distribution cylinder; a fuel gas gun is arranged in the central air distribution cylinder in the air box and used for injecting combustion-supporting fuel gas required for maintaining the combustion temperature; and waste liquid cyclone flame stabilizers are arranged at the end parts of the side air distribution cylinders and used for generating strong cyclone combustion-supporting air to maintain stable combustion of fuel gas. Waste gas guns are arranged in the side air distribution cylinders for ejecting waste gas to be treated, and the waste liquid guns are used for ejecting waste liquid to be treated. An ignition gun adopts a secondary ignition mode, small fire of the ignition gun is ignited through high-voltage direct-current discharge, and then large fire in the combustor is ignited through the small fire of the ignition gun; and a flame detector is used for detecting whether the small fireof the ignition gun is successfully ignited or not and whether the large fire in the combustor is in a safe range or not.

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
