Problems solved by technology

Since the annular diffuser is a glass tube with an inner and outer double-layer structure, its size, especially the outer diameter of the glass tube, generally has a large tolerance. The installation, fixing and transmission of the glass parts have always been subject to the dimensional error of the glass parts.

Abstract

The invention discloses a rotary gas absorption device. The rotary gas absorption device comprises a protecting transmission part, wherein the protecting transmission part is arranged outside a gas diffusion part (1) to package the gas diffusion part (1), is fixedly connected with the gas diffusion part (1) and is driven to rotate by a driving part (4). According to the rotary gas absorption device, the protecting transmission part is arranged to package the gas diffusion part and is fixedly connected with two ends of the gas diffusion part; the flatness of the end surface of a glass component can be controlled in a machining process, so that the assembling problem caused due to an outer diameter error of the gas diffusion part can be solved; meanwhile, the protecting transmission part packages the gas diffusion part, and the gas diffusion part is not influenced by a radial force and a torque, so that the crazing of glass is prevented, and the stability and reliability of a whole structure are greatly improved.

Description

technical field [0001] The present application relates to the technical field of detection equipment, in particular to a rotating gas absorption device. Background technique [0002] Air pollutants mainly include particulate matter and gaseous pollutants, among which gaseous pollutants are mainly sulfur-containing compounds, carbon oxides, nitrogen oxides, hydrocarbons, and fluorine-containing gases, chlorine-containing gases, etc. The monitoring of gaseous pollutants usually adopts sampling by diffusion separation and capture technology. Diffusion and capture technology uses the difference in the diffusion rate of gas and particles to set up an annular diffusion tube and attach the absorbent to the inner wall of the diffusion tube so that the gas molecules diffuse to the tube wall and are captured by the absorbent without affecting the particles. [0003] In the existing gas capture device, the circular diffusion tube rotates, so that the absorption liquid adheres to the i...
