Problems solved by technology

In the prior art, the chlorine-containing waste gas absorption tower adopts multi-stage series connection, and the drainage and alkali supplementation of each absorption tower are carried out separately. When a single tower changes alkali, the chlorine-containing waste gas directly enters the next process, and finally leads to the waste gas with excessive chlorine content. Emissions have a great impact on the air quality of the site and surrounding areas, and bring harm to human health and plant growth

Embodiment Construction

[0012] like figure 1 As shown, the chlorine-containing exhaust gas absorption system of the present invention includes a pre-washing tower, a primary tower and a secondary tower connected in series, and an alkali-adding pump connected with the secondary tower, and the pre-washing tower, the primary tower and the secondary tower Connected in sequence, the system also includes a control device, and the action of adding liquid caustic soda and draining liquid of the chlorine-containing waste gas absorption system is controlled by the control device.

[0013] Before use, pre-set the pH standard value of the absorption solution, generally 10-12. The alkali adding pump is controlled by the control device to add liquid alkali to the secondary tower. When the control device detects that the pH value of the first-stage tower absorption liquid is lower than the standard value, the first-stage tower absorption liquid is automatically discharged to the pre-washing tower, and the second-s...

Abstract

The invention discloses a chlorine-containing waste gas absorption system which comprises a prewashing tower, a first level tower and a second level tower which are sequentially connected with one another in series, an alkali pump connected with the second level tower, and a control device for controlling liquid alkali adding and draining movements of the chlorine-containing waste gas absorption system. The invention also discloses a chlorine-containing waste gas absorption method. Liquid alkali is added into the second level tower through the alkali pump. When the control device detects that the pH value of an absorption liquid of the first level tower is lower than a standard value, the absorption liquid of the first level tower is automatically discharged to the prewashing tower, and an absorption liquid of the second adsorption tower is automatically discharged to the first level tower. When the control device detects that the pH value of a washing liquid in the prewashing tower is lower than a standard value, the washing liquid is automatically discharged, and the absorption liquid of the first level tower is automatically discharged to the prewashing tower. According to the system provided by the invention, the pH value of the liquid in each level tower is maintained in a high state all the time, so that chlorine-containing waste gas is discharged by reaching the standard.

Description

technical field [0001] The invention relates to a chlorine-containing waste gas treatment system, in particular to a chlorine-containing waste gas absorption system. Background technique [0002] In order to prevent the chlorine-containing waste gas from industrial production from entering the atmosphere and causing environmental pollution, an absorption tower is generally used to absorb the chlorine-containing waste gas. In the prior art, the chlorine-containing waste gas absorption tower adopts multi-stage series connection, and the drainage and alkali supplementation of each absorption tower are carried out separately. When a single tower changes alkali, the chlorine-containing waste gas directly enters the next process, and finally leads to the waste gas with excessive chlorine content. Emissions have a great impact on the air quality of the site and surrounding areas, and bring harm to human health and plant growth. Contents of the invention [0003] In view of the a...
