Description

An organic waste gas purification and combustion device used in an epoxy resin production line

technical field

The utility model relates to a heat exchange type waste gas purification combustion device, which is mainly used for purifying and treating high-concentration industrial organic waste gas produced in the production process of epoxy resin. the

Background technique

The existing volatile organic waste gas treatment mostly adopts the combustion method. At high temperature (above 1100°C), the volatile organic compounds contained in the waste gas react with oxygen in the air through high temperature to generate carbon dioxide and water. The main reaction equipment is a combustion reactor. The regenerative combustion reactor is a high-efficiency and energy-saving reactor for treating combustible waste gas. Most of the regenerative combustion reactors in the prior art adopt a two-bed regenerator structure, which is the simplest regenerative combustion reaction system. The two-bed regenerator structure stores the heat of the high-temperature gas coming out of the combustion chamber, and preheats the organic waste gas entering the regenerator bed. Ceramic heat storage materials are used to absorb and release heat, realizing the ultimate waste heat recovery, and the heat recovery efficiency can reach 95% % or more, the exhaust gas removal rate reaches more than 99%, which solves the problem of high energy consumption and effectively protects the environment. However, since the organic waste gas entering the regenerative combustion reactor must undergo pretreatment such as dust removal, the arrangement is complicated and the floor area is large, which is too complicated for the treatment of small and medium-sized organic waste gases; at the same time, the regenerative combustion reactor A part of the untreated waste gas will remain in the regenerator, which will be brought into the environment when the waste gas is discharged, causing environmental pollution. the
