Problems solved by technology

At present, countercurrent absorption is the mainstream process of chemical deodorization technology. Although it has the advantage of high absorption rate, it also has the problem that the contact interface area between gas and liquid is too small, resulting in low mass transfer and reaction efficiency, and easy to produce liquid. Disadvantages such as pan and large pressure loss

Abstract

The invention discloses an efficient chemical deodorization device and method. The device comprises: an absorption liquid storage tank, wherein a reaction pipe is connected to a gas inlet of the absorption liquid storage tank, and a demister connected to a gas outlet of the absorption liquid storage tank; a liquid spraying pipe, wherein the lower end of the liquid spraying pipe is connected with the reaction pipe, and an external fan connected with the upper end of the liquid spraying pipe; and a circulation mechanism, wherein the extraction end of the circulation mechanism is connected with the liquid outlet of the absorption liquid storage tank, and the discharge end of the circulating mechanism is connected with the liquid spraying pipe. According to the efficient chemical deodorization device, a gas-liquid co-flow chemical technology is adopted; and the device is large in treatment capacity, small in pressure drop, free of a flooding phenomenon, and capable of remarkably reducing a tower diameter and a tower height and decreasing the investment cost of the device.

Description

technical field [0001] The invention belongs to the technical field of chemical deodorization, and more specifically relates to a high-efficiency chemical deodorization device and method. Background technique [0002] Chemical deodorization technology is the process of absorbing and removing gaseous pollutants in malodorous gas through chemical absorption solution. According to the gas-liquid contact form, the absorption process can be divided into two types: cocurrent (cocurrent) absorption and countercurrent (countercurrent) absorption. At present, countercurrent absorption is the mainstream process of chemical deodorization technology. Although it has the advantage of high absorption rate, it also has the problem that the contact interface area between gas and liquid is too small, resulting in low mass transfer and reaction efficiency, and easy to produce liquid. Disadvantages such as pan and large pressure loss. Contents of the invention [0003] The purpose of the p...
