Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mixed reaction equipment, in particular to a reaction kettle for liquid hazardous chemicals. Background Art
[0002] In the production process of chemicals, a reactor is needed to achieve mixing and reaction of chemicals in order to obtain the required chemical products. The reactor body is generally made of corrosion-resistant materials such as stainless steel, which can withstand a certain pressure and temperature. A stirring device is provided inside the reactor to ensure that the reaction materials are fully mixed, making the reaction more uniform and efficient.
[0003] After completing a cycle of production, the reactor needs to be cleaned to prevent cross-contamination of products and to prevent the residual reactants of the previous cycle from being mixed into the products of the next cycle, thereby changing the product composition and properties and affecting the product quality. When cleaning the reactor, water mixed with a cleaning solvent is generally used to clean the reactor directly. However, in the existing reactor cleaning process, the nozzles arranged in the reactor have a fixed position, and their spraying angles and coverage are limited. There are many spraying dead angles that are difficult for the nozzles to reach. At the same time, during the cleaning operation, some reactors will directly fill the reactor with cleaning liquid and cooperate with the stirring mechanism and solvent to clean the reactor. However, since the cleaning liquid storage in the reactor has an upper limit, the areas above the cleaning liquid level and the bottom of the reactor top cover cannot be effectively cleaned, resulting in a limited cleaning coverage in the reactor.
