Description

Technical Field

[0001] The utility model relates to the technical field of boiler smoke collection, and more specifically, to an industrial boiler smoke collection device. 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 using coal as raw material. This is a typical industrial boiler. Most industrial boilers are still coal-fired. In the use of industrial boilers, flue gas collection devices are used. The flue gas collection device is used to collect the flue gas, filter the smoke and dust, and then pass it into the waste heat recovery device to recycle the waste heat in the flue gas.

[0003] The current industrial boiler flue gas collection device has only a simple filtering structure inside, which easily causes smoke to adhere to the filter plate, causing blockage, thereby affecting the circulation of smoke. At the same time, the filtered smoke impurities are not easy to be discharged from the device. Utility Model Content
