Acid gas purification device

Abstract

The invention discloses an acid gas purification device, comprising a box, wherein a spacer plate is arranged in the box, the upper end of the spacer plate is provided with a purification cavity, the lower end of the spacer plate is provided with a gas inlet cavity, the left side of the gas inlet cavity is provided with a gas inlet pipe, the gas inlet pipe is provided with a high-pressure pump, a fixing sleeve is vertically fixed to the middle postion of the upper end of the spacer plate, upper and lower through openings are formed in the fixing sleeve, an inner cavity of the fixing sleeve is communicated with the gas inlet cavity, a drive shaft is arranged in the fixing sleeve in a penetrating way, the fixing sleeve is provided with a No. 1 rigid bearing matched with the drive shaft, the upper end of the drive shaft penetrates through the upper end of the box, and is connected with an output end of a drive motor, a gas guide passage is arranged in the drive shaft, and a lower end opening of the gas guide passage is communicated with the gas inlet cavity. The acid gas purification device is simple and reasonable in structure, rotational gas injection is realized, thus a contact area between injected gas and purifying liquid is increased, when bubbles float upward, the mixing degree of waste gas and the liquid can be further increased by stirring wires and a stirring screen, thus the purification effect of the device is greatly improved, and the practicability is high.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an acid gas purification device. Background technique [0002] During the electrowinning step of certain metallurgical methods, gas is formed at the anode of the electrolytic cell, and gas bubbles then float to the surface of the acidic electrolyte. The generated bubbles were up to 100 microns in diameter. When these bubbles reach the surface, they collapse (burst). When the bubbles burst, they generate an aerosol of electrolytes or particles suspended in the air, thereby generating acid mist, which will cause harm to the working environment and the human body. It is necessary to reduce the content of acid mist before discharge, and some existing In the equipment, when the discharge of acid mist is large or the speed is fast, the contact time between acid mist and alkaline liquid is short, resulting in incomplete purification. In order to solve the above proble...
