Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to industrial boiler waste gas treatment equipment. Background Art

[0002] There are two types of industrial boiler products. One is steam, which is used for power generation or gas supply. For example, fertilizer plants can use steam vaporization to synthesize fertilizers with coal as raw material. This is a typical industrial boiler. Most industrial boilers are still coal-fired. Gas-fired ones are generally waste heat boilers used to recover waste heat. The most common industrial boiler is a circulating fluidized bed boiler. Industrial boilers are important thermal power equipment. When some materials are processed, industrial boilers need to be used. Industrial boilers will produce some exhaust gas during use. Direct discharge of these exhaust gases will cause environmental pollution. In order to protect the environment, the exhaust gas needs to be purified. The filter inside the purification device needs to be replaced after a certain period of use to ensure the purification effect.

[0003] However, some existing filtering devices are prone to clogging after long-term use and cannot be cleaned automatically. They need to be manually disassembled and replaced regularly, which is time-consuming and labor-intensive. At the same time, the circular filter box needs to be shut down when disassembling, which wastes a lot of time and reduces the efficiency of the filtering work. For this reason, we propose an industrial boiler exhaust gas treatment equipment to solve the above problems. Utility Model Content
