Flue gas purification treatment equipment

Abstract

The invention belongs to the technical field of dust removal and environmental protection, and particularly relates to flue gas purification treatment equipment. The flue gas purification treatment equipment comprises a smoke inlet pipe, an electrostatic dust collector, a bag dust collector and an agglomeration liquid atomizing and spraying mechanism; a smoke inlet is arranged at one end of the smoke inlet pipe, and the other end of the smoke inlet pipe is connected and communicated with an inlet flue of the bag dust collector; the electrostatic dust collector is mounted in the smoke inlet pipe; the agglomeration liquid atomizing and spraying mechanism is provided with an atomizing and spraying nozzle located in the inlet flue, and is used for spraying misty agglomeration liquid into the inlet flue through the atomizing and spraying nozzle; a tail gas treatment device is communicated to a purified smoke outlet of the bag dust collector. The flue gas purification treatment equipment hasthe advantages of simple and reasonable structural design, dust removal based on multiple mixed methods, high dust removal efficiency and good effect.

Description

technical field [0001] The invention belongs to the technical field of dust removal and environmental protection, and in particular relates to flue gas purification treatment equipment. Background technique [0002] The bag filter is suitable for collecting fine, dry, non-fibrous dust, and it is difficult to meet the ultra-low emission requirements by using the bag filter alone. Reason for failure: [0003] 1) The working characteristic of the bag filter is that the dust in the flue gas is blocked on the surface of the filter bag while the flue gas passes through the filter bag, and the fine particles cannot escape through the filter bag; [0004] 2) Although the filter bag technology is also continuously improving the filtration efficiency, such as the use of film-coated filter materials or ultra-fine fibers, etc., the effect on ultra-fine dust below PM. is limited; [0005] 3) Reduce the speed of flue gas passing through the filter bag, that is, the filtering wind speed....

Problems solved by technology

[0004] 2) Although the filter bag technology is also continuously improving the filtration efficiency, such as the use of film-coated filter materials or ultra-fine fibers, etc., the effect on ultra-fine dust below PM. is limited;

[0005] 3) Reduce the speed of flue gas passing through the filter bag, that is, the filtering wind speed. Although the passing fine dust is reduced, the required filtering area is large

The equipment is bulky, occupies a large area, and the investment cost is high
