Hydrogen chloride generator based on pressure control

Abstract

The invention relates to the technical field of hydrogen chloride preparation, in particular to a hydrogen chloride generator based on pressure control, which comprises supporting legs, a reaction kettle is fixedly mounted on the upper end surfaces of the supporting legs, a feed inlet is formed in the upper side of the front end surface of the reaction kettle, and a liquid storage barrel I is fixedly mounted on the left end surface of the reaction kettle; a second liquid storage barrel is fixedly installed on the right end face of the reaction kettle, a reaction control mechanism is arranged in the reaction kettle and comprises a first rod, a second rod, a first rack, a first spraying pipe, a third rod, a fourth rod, a second rack and a second spraying pipe, and a first movable plate is movably installed on the left side in the reaction kettle. According to the hydrogen chloride generator equipment, the conveying of hydrogen chloride gas and the supplement of reaction raw materials can be automatically completed according to the change of internal gas pressure, compared with a traditional manual raw material adding method, a large amount of manpower is saved, the working procedures of conveying gas and supplementing the raw materials can be automatically completed, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of hydrogen chloride preparation, in particular to a pressure-controlled hydrogen chloride generator. Background technique [0002] The common method for preparing hydrogen chloride is to add concentrated sulfuric acid to concentrated hydrochloric acid, because concentrated sulfuric acid is hygroscopic, the solvent water in concentrated hydrochloric acid will decrease, and the solute HCL will volatilize. Volatile, so as to achieve the purpose of producing HCL gas. [0003] In real life, the method of adding concentrated sulfuric acid to concentrated hydrochloric acid is often used to prepare hydrogen chloride gas. Usually, the staff needs to add raw materials to the generator regularly to ensure the continuous preparation of hydrogen chloride gas, and it is necessary to observe the internal pressure value for a long time. In order to avoid potential safety hazards, especially for the industrial production o...

[0003] In real life, the method of adding concentrated sulfuric acid to concentrated hydrochloric acid is often used to prepare hydrogen chloride gas. Usually, the staff needs to add raw materials to the generator regularly to ensure the continuous preparation of hydrogen chloride gas, and it is necessary to observe the internal pressure value for a long time. To avoid potential safety hazards, especially for the industrial production of hydrogen chloride gas, the long-term operation of the equipment requires a large amount of human resources to continuously replenish the raw materials inside the generator, which wastes human resources and increases production costs.
