Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to a high-efficiency composite desulfurization device. Background Art

[0002] It is well known that the raw material sulfides used in cement production are mostly pyrite and marcasite, as well as some monosulfides.

[0003] After cement is used as fuel to produce fuel, the main harmful flue gas is sulfide.

[0004] Therefore, it is necessary to desulfurize the waste gas from cement production.

[0005] During the flue gas emission process of cement production, the flue gas contains not only sulfides but also dust.

[0006] During the use of the existing desulfurization structure, the flue gas impurity removal and desulfurization are carried out in a distributed manner, resulting in complex and crisscrossed flue gas treatment pipelines, which increases the difficulty of future maintenance.

[0007] To this end, we propose a high-efficiency composite desulfurization device to solve the existing problems. Utility Model Content

[0021] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0022] 1. The utility model high-efficiency composite desulfurization device can introduce the flue gas of cement production into the tank body through the flue during use. In this process, the pump body sucks the alkali solution in the left chamber and sprays it through the water spray ring, thereby forming a water curtain.
