Reaction kettle provided with internal cleaning device

Abstract

The invention provides a reaction kettle provided with an internal cleaning device, which belongs to the field of chemical equipment and is used for automatic internal cleaning of the reaction kettle. The invention adopts the main realization means that: a circle of high-pressure spraying pipe is arranged in the reaction kettle; multiple high-pressure liquid streams impact the reaction kettle wall and each component in the reaction kettle; a reaction kettle stirrer is opened at the same time to cooperatively stir; reaction residual liquid remained on each component of the reaction kettle is fully flushed by a cleaning agent, and is diluted and cleaned; and the reaction residual liquid is discharged from a discharge opening of the reaction kettle together with the cleaning agent. Therefore, the way of manually cleaning the reaction kettle or slowly flooding a large amount of solvent to clean the reaction kettle is avoided.

Description

Technical field: [0001] The invention relates to a reaction kettle provided with an internal cleaning device, which belongs to the field of chemical equipment maintenance and is used for automatic internal cleaning of the reaction kettle. Background technique: [0002] At present, chemical reactors at home and abroad are generally divided into two working forms, namely continuous working form and staged working form. In the continuous working form, there is no contradiction between the chemical products in the reactor and the unreacted chemical raw materials. For example, the production of all-purpose glue is mainly a dissolution process. After the processing of the reactor is completed and the finished product is discharged, there is no contradiction between the residual liquid of the finished product remaining in the kettle and the newly added raw materials such as rubber, petroleum resin, and solvent. It will adversely affect the next batch of reactions; and in other reac...

Problems solved by technology

[0003] In order to solve the problem that the inside of the reaction kettle cannot be cleaned automatically, or a large amount of organic solvent is consumed during cleaning, a reaction kettle with an internal cleaning device is proposed. The main means of realization is as follows. High-pressure spray pipe, the high-pressure spray pipe is installed in a ring shape, under the cover of the reaction kettle, above the stirring device, the high-pressure spray pipe can be equipped with a mounting bracket, and multiple spray holes are opened on the pipe, and the spray pipe passes through The cleaning agent pipeline is externally connected to the cleaning pump, and the cleaning pump is connected to the cleaning agent tank
