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, the effect on ultra-fine dust below PM2.5 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

Embodiment

[0031] Example: such as figure 1 As shown, the flue gas ultra-clean treatment system of this embodiment includes a bag filter 1, an agglomerating agent solution liquid source 2 and an atomizing spray device 3;

[0032] The above-mentioned bag filter 1 has an inlet flue 11, and the above-mentioned atomizing spray device 3 is installed in the above-mentioned inlet flue 11;

[0033] The above-mentioned atomizing spray device 3 communicates with the above-mentioned agglomerating agent solution source 2 through a conveying device 4 .

[0034] During use, the dust enters the inlet flue 11, and at the same time, the conveying device 4 transports the agglomerating agent solution to the atomizing spray device 3, and atomizes and sprays the dust in the inlet flue 11, so that the agglomerating agent is fully mixed with the inlet flue. The smoke and dust in 11 are in contact, so that the small particles of smoke and dust are chemically agglomerated into large particles under the action o...

Abstract

The invention relates to a flue gas dedusting technology, in particular to a flue gas ultra-clean treatment system. The flue gas ultra-clean treatment system comprises a bag type dust collector, an agglomerating agent solution source and an atomizing and sprinkling device, wherein the bag type dust collector is provided with an inlet flue; the atomizing and sprinkling device is mounted in the inlet flue; the atomizing and sprinkling device is in communication with the agglomerating agent solution source through a conveying pipe; and a conveying device is arranged on the conveying pipe. The system has the advantages of being simple and reasonable in structural design, significantly improving the dust removal efficiency and effect, improving the flue gas emission index, and reducing the usecost.

Description

technical field [0001] The invention relates to flue gas dedusting technology, in particular to a flue gas ultra-clean treatment system. Background technique [0002] Today's dust collectors are mainly electrostatic precipitators and bag dust collectors. Although it is generally believed that bag dust collectors are suitable for capturing fine, dry, non-fibrous dust and have specific advantages over electrostatic precipitators, it is difficult to use bag dust collectors alone. Meet ultra-low emission requirements. 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, the effect on ultra-fine dus...
