Problems solved by technology

[0004] The present invention aims to solve the problem that the flue gas purification device of the existing boiler purifies the flue gas, because the flue gas contains a large number of particles, and the large amount of particles in the flue gas affects the flue gas purification effect. Finally, the flue gas is separated from the solid smoke first, and then the flue gas that has been separated from the solid smoke is sent to the flue gas purification device for flue gas purification, and the degree of solid smoke separation can be freely controlled for use in boilers. The flue gas purification system and its operation method

Abstract

The invention discloses a flue gas purification system for a boiler and an operation method thereof. It belongs to the technical field of flue gas purification. After the flue gas comes out of the boiler, the flue gas is firstly separated from the solid smoke, and then the flue gas that has been separated from the solid smoke is sent to the flue gas purification device for flue gas purification. And the degree of solid smoke separation can be freely controlled. The flue gas purification system for the boiler, including the boiler and the flue gas purification device, also includes the No. 1 vertical pipe with a rectangular cross-section of the inner tube cavity, the smoke extractor, the memory and the controller; on the left side of the No. 1 vertical pipe The side outer tube wall is provided with a left bracket, and the left bracket is provided with a No. 1 cylinder with a telescopic rod arranged towards the right.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a flue gas purification system for a boiler and an operating method thereof. Background technique [0002] At present, in the treatment of boiler flue gas, the flue gas from the boiler is generally directly introduced into the flue gas purification device for flue gas purification, but each time the flue gas sent to the flue gas purification device contains a large amount of Particles, and the amount of particles contained in the flue gas entering the flue gas purification device at different time periods is different, but the flue gas purification device adds purifying agents to purify the flue gas according to the same purification treatment requirements at every moment Yes, and the amount of particles in the flue gas and the size of the particles have a greater impact on the purification effect of the flue gas purification. [0003] Larger particles make it diff...
