Problems solved by technology

[0003] Commonly used desulfurization and dust removal towers use 316L stainless steel swirl layer as the desulfurization and dust removal layer, and add a spray system for soot precipitation. However, the gap between the stainless steel swirl layer is large, so the contact surface between the flue gas and the liquid medicine is small, and the dust removal and desulfurization effect is not good.

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the desulfurization and dust removal system includes tower body 1, flue gas inlet 2, discharge port 3, first-level desulfurization layer 4, second-level desulfurization layer 5, third-level desulfurization layer 6 and circulating water system 7, and flue gas inlet 2 is set On the bottom side of the tower body 1, the first desulfurization layer 3, the second desulfurization layer 4, and the third desulfurization layer 5 are arranged in the tower body 1 from bottom to top, and the circulating water system 7 is connected with the first desulfurization layer 4 and the second desulfurization layer respectively. The layer 5 and the third-stage desulfurization layer 6 are connected, and the third-stage desulfurization layer 6 is a biofilm layer. The flue gas enters from the flue gas inlet 2, and passes through the first-level desul...

Abstract

The invention discloses a desulfurizing and dedusting system. The desulfurizing and dedusting system comprises a tower body, a flue gas inlet, a discharging outlet, a first-stage desulfurizing layer, a second-stage desulfurizing layer, a third-stage desulfurizing layer and a circulating water system, wherein the flue gas inlet is formed in one side of the bottom part of the tower body; the first-stage desulfurizing layer, the second desulfurizing layer and the third-stage desulfurizing layer are arranged in the tower body from bottom to top; the circulating water system is respectively connected with the first-stage desulfurizing layer, the second desulfurizing layer and the third-stage desulfurizing layer; the third-stage desulfurizing layer is a biological membrane layer. The third-stage desulfurizing layer is filled with a biological membrane, and the biological membrane is small in gaps, so that flue gas is in full contact reaction with liquid medicine, dust is not easy to pass, and the liquid medicine attached to the biological membrane can drop down after being adhered to the dust; the biological membrane layer is 1 to 2 m in height, the adsorption effect is good, exhaust gas passing through the biological membrane is greatly purified, and national standard is met.

Description

technical field [0001] The invention relates to the field of environmental protection devices, in particular to a sulfur and dust removal system. Background technique [0002] The desulfurization and dedusting tower is an important device used to treat the exhaust gas of large factories. In order to make the discharged gas meet the national standards and reduce environmental pollution as much as possible, the desulfurization and dedusting structural devices in the desulfurization and dedusting tower need to be paid attention to. [0003] Commonly used desulfurization and dust removal towers use 316L stainless steel swirl layer as the desulfurization and dust removal layer, and add a spray system for soot precipitation. However, the stainless steel swirl layer has a large gap, so the contact surface between the flue gas and the liquid medicine is small, and the dust removal and desulfurization effect is not good. Contents of the invention [0004] The object of the present ...
