Problems solved by technology

[0003] In the process of spraying the washing liquid (absorbent) downwards in the washing tower, a considerable part of the washing liquid is sprayed onto the tower wall, and the washing liquid flows down the tower wall and cannot fully contact with the gas to be absorbed, so it cannot react , this part of the washing liquid is not fully utilized, resulting in waste

Embodiment Construction

[0013] As shown in the drawings, the washing tower of the present invention includes a demisting area 1, a spraying area 4 and a slurry tank 5 from top to bottom, and the spraying area 4 includes a spraying washing pipeline 2. In the present invention, several wall flow baffles 3 are installed on the washing tower along the inner wall of the tower. The wall flow baffles 3 are arranged in a continuous ring along the inner wall of the washing tower. The board 3 can be arranged in a single layer or in multiple layers. The wall flow baffle 3 collects the detergent flowing downward along the tower wall, and forms a circle of absorbent film under the wall flow baffle 3, so that the scrubbed gas flowing upward close to the tower wall can fully mix with these absorbents. contact and reaction, and finally achieve the purpose of making full use of the absorbent.

[0014] Due to the existence of the wall flow baffle 3, the gas that needs to be scrubbed close to the tower wall will be fo...

Abstract

The present invention discloses a washing tower, which comprises a demisting area, a spray area and a slurry pool from the top down. The spray area comprises a spray layer and a spray washing pipe. The interior wall of the washing tower is equipped with a plurality of wall flow baffles to stop a wall-adhesive flow. With the baffles, the present invention can promote the use efficiency of a detergent and reduce the escape rate of the washed gas along a weak spray area on the tower wall.

Description

technical field [0001] The invention relates to a washing tower, which is suitable for the gas washing process. Background technique [0002] In order to remove some gases in the mixed gas in the industry, a scrubbing solution that can react with these gases is often used to react with the gases that need to be removed by reverse spraying to remove these gases. Common scrubbers such as SO used in wet desulfurization processes 2 The absorption tower is to use the downward spraying of limestone slurry or ammonia and SO in the flue gas 2 Reaction to generate gypsum or ammonium sulfate to remove SO 2 the goal of. [0003] In the process of spraying the washing liquid (absorbent) downwards in the washing tower, a considerable part of the washing liquid is sprayed onto the tower wall, and the washing liquid flows down the tower wall and cannot fully contact with the gas to be absorbed, so it cannot react , This part of the washing liquid is not fully utilized, resulting in was...
