High-efficiency energy-saving vertical PP acid-base waste gas washing tower

Abstract

The invention discloses a high-efficiency energy-saving vertical PP acid-base waste gas washing tower which comprises a tower body, an acid pump, a first medicine tank, an alkali pump, a second medicine tank, a first packing layer, a first spraying mechanism, a second packing layer and a second spraying mechanism, wherein a first observation window is formed above one side of the tower body, a second observation window is arranged on one side of the tower body, and is located below the first observation window, an air inlet is formed in one side of the tower body, and is located below the second observation window, a first supporting plate is arranged at the bottom of the other side of the tower body, the top of the first supporting plate is provided with the acid pump, the top of the acidpump is provided with a first connecting pipe, the top end of the first connecting pipe is connected with the top of the other side of the tower body, the first medicine tank is arranged on one sideof the acid pump, and the second supporting plate is arranged on the symmetric side of the other side of the tower body; a generated waste liquid can be recycled, later cycle use is facilitated, resources are saved, meanwhile, all steps of acid and alkali waste gas purification are completed in a washing tower, so that the purification efficiency is greatly improved.

Description

Technical field [0001] The invention relates to the field of a vertical PP acid-base waste gas scrubber, in particular to a high-efficiency and energy-saving vertical PP acid-base waste gas scrubber. Background technique [0002] The scrubber is a new type of gas purification treatment equipment, which is improved on the basis of the floating packing layer gas purifier. It is widely used in the pretreatment of industrial waste gas purification and dust removal. The purification effect is very good. The contact between gas and liquid, and the pollutants in the gas are transferred to the liquid, and then the clean gas is separated from the contaminated liquid to purify the air. The exhaust gas passes through the filled acid mist scrubber and adopts gas-liquid reverse Absorption treatment, that is, the liquid is sprayed down from the top of the tower in mist (or small droplets), and the exhaust gas is contacted by the tower body (countercurrent flow) to achieve the purpose of gas-li...

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-efficiency and energy-saving vertical PP acid-base waste gas scrubber. In order to overcome the above-mentioned need for multiple scrubbers to purify the acid and alkali of the waste gas, the space occupied is large and the whole process is complicated. In practical application The process takes a long time; at the same time, in the process of spraying and neutralizing the acid-base waste gas, the ordinary spraying method often needs to consume a large amount of acid-base solution to complete the neutralization, and the neutralization effect is poor at the same time.
