Problems solved by technology

In the panel manufacturing process of TFT-LCD panel photoelectric manufacturing, although the dimethyl sulfoxide contained in the stripping agent in the stripping process is a liquid with high boiling point, water solubility and low volatility, it is During the treatment of the waste gas, it is very easy to form the gaseous pollutants of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS), or produce acidic and corrosive gases such as sulfur dioxide, which is still unsuitable. in the combustion method as the final treatment
[0005] However, in the above-mentioned existing device and method, when treating organic waste gas, the adsorption material in the concentration wheel is not easy to renew and regenerate, and there are still doubts about gas leakage during treatment, so further improvement and more comprehensive design are needed. The invention provides a rotary solvent recovery device and method to achieve the best treatment efficiency and the safest design

Abstract

The present invention relates to a device and method for rotary solvent recovery, wherein the device includes: a fan, a rotary swivel adsorber, a desorption gas source, a condenser and a separation tank, and the rotary solvent recovery In the device, the rotary swivel adsorber is composed of a plurality of adsorption boxes (Block), and includes: an isolation box, a driving deceleration motor and a sealing member, and the rotary swivel adsorber is reduced by the sealing member. For the leakage of the adsorber during the treatment of organic waste gas, the use of the adsorption box can also facilitate the renewal and replacement of the adsorbent in it, making the rotary solvent recovery device of the present invention more efficient, safe and convenient.

Description

technical field [0001] The present invention relates to a rotary solvent recovery device and method, in particular to a device and method for recovering organic solvent contained in the organic waste gas when treating the organic waste gas. Background technique [0002] Recently, the international community has paid more and more attention to environmental protection issues and industrial safety and health. Considering the harm of industrial waste gas to the environment, workers and the general public, the emission standards for industrial waste gas have become increasingly stringent. Domestic and foreign regulations have formulated concentration and odor emissions. standard. For the treatment of volatile organic gases in industrial waste gas, the condensation method is often used to collect them when the concentration is high, and the physical adsorption method is used to concentrate and treat them when the concentration is low and the air volume is large, and then sent to ...
