Description

Technical Field

[0001] This utility model relates to the field of boiler flue gas purification technology, specifically a power plant boiler flue gas purification device. Background Technology

[0002] A boiler is an energy conversion device. The input energy includes fuel chemical energy and electrical energy. It can output steam, high-temperature water or organic heat carrier with thermal energy. The hot water or steam produced can be used to provide heating for industrial production and people's lives. It can also be converted into mechanical energy by a steam power device, and then into electrical energy by a generator.

[0003] Patent application number 201822014917.3 discloses a boiler flue gas dust removal and purification device for power plants, including a connecting pipe, a filter chamber, a desulfurization chamber, and a glass microporous filter. A pipe is provided on the right side of the connecting pipe, and the filter chamber is fixedly connected to the right side of the pipe. The filter chamber has filter screens evenly distributed inside. The right side of the filter chamber is connected to the desulfurization chamber through a pipe, and a desulfurization component is fixedly connected inside the desulfurization chamber. The desulfurization component includes a rotating base, a metal pipe, a hollow pipe, and a water spray nozzle.

[0004] The boiler flue gas dust removal and purification device used in this power plant, by adding a desulfurization chamber, uses a water pump to draw up the desulfurizing agent and sprays water mist in a rotating jet manner to degrade and separate the sulfur components in the boiler flue gas. It is relatively environmentally friendly and practical. However, there are still areas for improvement. For example, the sealing between the filter screen and the filter chamber is poor, resulting in poor performance and failing to meet current needs. Utility Model Content
