Exhaust gas washing purification system and exhaust gas purification method

Abstract

The invention discloses a waste gas rinsing and purification system, which comprises a waste gas purification shell in a rotary structure, the waste gas purification shell, the inside of the waste gas purification shell is a sulfur-containing waste gas purification chamber, and the sulfur-containing waste gas purification chamber There is a rinsing absorption liquid at the bottom of the spray dispersing channel; the lower part of the initial velocity of the dispersing water spray sprayed upwards in a spiral form from the upper end of the spray dispersing channel of the present invention will fall to the center of the annular swirl desulfurization rinsing chamber under the action of gravity, and The swirling flow in the annular swirl desulfurization rinsing chamber makes a spiral downward movement, and finally falls to the bottom of the sulfur-containing exhaust gas purification chamber, so that the entire annular swirl desulfurization rinsing chamber is filled with spirally falling diluent spray. Furthermore, the sulfur-containing waste gas swirl in the annular swirl desulfurization rinsing chamber is fully contacted and fused with the spirally falling diluent spray, thereby realizing the second absorption of the sulfur-containing waste gas.

Description

technical field [0001] The invention belongs to the field of industrial waste gas desulfurization. Background technique [0002] The sulfur dioxide gas in the industrial waste gas needs to be absorbed by the absorption tower and then discharged to the outside. The existing absorption tower mainly uses the water pipe to pump the lime slurry to a high place and release it to form a continuous rain effect, so as to achieve the effect of full contact with the waste gas In this way, the raindrops fall faster and the time of staying in the air is limited, resulting in limited absorption efficiency of a single shower. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a waste gas rinsing purification system with higher absorption efficiency. [0004] Technical solution: In order to achieve the above purpose, the waste gas rinsing and purification system of the present invention inclu...
