Abstract

The invention discloses an HCL gas absorption system, solving the problem that the existing device for absorbing HCL gas in waste gas is complicated in structure and is low in absorbing efficiency of HCL gas in the waste gas. According to the technical scheme, the HCL gas absorption system comprises a receiving tank, a falling film absorber, an absorbing tower and a finished product liquid outlet communicated with the receiving tank, wherein the falling film absorber is provided with an absorbing hole. The HCL gas absorption system is characterized in that the falling film absorber is communicated with the receiving tank, the absorbing tower is communicated with the falling film absorber through a pressure-reducing pipe, the receiving tank is communicated with a spray head arranged at the upper end part of the absorbing tower through a circulating pipe, the spray head is used for spraying absorbing liquid into the absorbing tower, the circulating pipe is provided with a circulating pump, and a vacuum unit is communicated with the spray head through a vacuum pipe.

Description

technical field [0001] The invention relates to a treatment device for treating waste gas, in particular to an absorption system for absorbing HCL gas in the waste gas. Background technique [0002] In the pharmaceutical and chemical industries, there are often some waste gases associated with them. The components of these waste gases are relatively complex. Considering the purpose of environmental protection, these waste gases need to be treated. As an acidic gas, HCL is relatively harmful to the environment. Before the exhaust gas is discharged to the outside, it is necessary to absorb the HCL in the exhaust gas. [0003] A Chinese utility model patent (patent number: 201020228119.1) discloses a by-product hydrochloric acid absorption device for potassium sulfate production, which belongs to the technical field of potassium sulfate production. and the induced draft fan, the water inlet pipeline of the high-level acid-making bucket is connected to the process water pipelin...
