Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lightness removal towers, in particular to an anti-blocking lightness removal tower. Background Art
[0002] Boron trichloride, with the molecular formula of BCl3, has a wide range of applications. In the field of pharmaceutical intermediates, carboxylic acids treated with boron trichloride and alcohols can be added to obtain carboxylic acid esters in a simple, efficient and high-yield manner. In the field of fine chemicals, boron trichloride can be used as a catalyst for high-purity boron and organic compounds. In the field of steel manufacturing, boron trichloride as an additive can boronize steel, making it have high hardness, high melting point, good electrical and magnetic functions, high corrosion resistance, and improve the service life of steel. In the field of silicate processing, boron trichloride is an indispensable cosolvent. Boron trichloride can be used as a rocket propellant in the aerospace field. Most importantly, in semiconductor manufacturing, boron trichloride can be mixed with other gases to form a thin film through chemical vapor deposition, and is a basic substance for manufacturing optical fibers and integrated circuit BPG materials. In the plasma etching process, boron trichloride is an important gas for metal aluminum etching, and can also be used in processes such as doping and ion implantation in IC manufacturing. The existing boron trichloride is prepared by gasifying industrial-grade boron trichloride through a heater and sending it to a molecular sieve dehydrator for dehydration; after dehydration, it is sent to a phosgene decomposer to decompose the phosgene into chlorine and carbon monoxide under a catalyst and high temperature; the gas from the phosgene decomposer is cooled in two stages and sent to a light-removing tower; the light components in the raw material are removed in the light-removing tower, and the liquid from the bottom of the light-removing tower is sent to a heavy-removing tower; the heavy components in the raw material are removed from the bottom of the heavy-removing tower, and 6N-grade high-purity boron trichloride is obtained from the top of the heavy-removing tower.
[0003] In some existing light removal towers used for preparing boron trichloride, filters are provided for light removal filtering. The filtered gas may contain some impurities and other substances that may become solid particles or liquid substances when passing through the filter due to reduced temperature, thereby accumulating and clogging the filter holes, thus affecting the filtering effect. In addition, the filter is not easy to disassemble for replacement or cleaning after long-term use, which makes it inconvenient to use. In the published Chinese patent application, publication number: CN218609334U, patent name: a delightening tower with anti-blocking function, although the reciprocating screw is driven to rotate by a motor and the brush holder is driven to move by a sliding block, and the filter is cleaned by a mobile brush holder, which has a certain cleaning effect; however, since the raw materials inside the delightening tower produce a large amount of gas and reactants after the reaction, the reciprocating screw is corroded to a great extent, and the reactants are attached to the threads of the reciprocating screw. The agglomerated reactants cause a large blockage to the reciprocating screw, making it impossible for the reciprocating screw to effectively drive the brush holder to move. Therefore, in order to solve the problem that the brush holder cannot be effectively moved and the brush holder cannot be effectively moved to clean the filter in the prior art, this application is specially proposed to solve it.
