Automatic flushing device for reaction kettle in petrochemical industry and cleaning method thereof

Abstract

The invention relates to an automatic flushing device for a reaction kettle in the petrochemical industry, comprising a cutout valve installed on the cleaning opening of the reaction kettle and communicating with the reaction kettle, a connecting flange communicating with the cutout valve and provided with a replacement storage cavity, and a hydraulic cylinder cleaning mechanism installed on the connecting flange and used for cleaning the reaction kettle. The invention has the characteristics that only high-pressure water is used as the cleaning power source and the lifting power source of a source automatic cleaning mechanism is abandoned; with a simple structure and reliable operation, the automatic flushing device is particularly suitable for dangerous petrochemical industry and worth popularizing; the closed cleaning of the reaction kettle can be skillfully realized by the cleaning mechanism of the hydraulic cylinder. Without arranging packing seal and other devices, the productionefficiency of the reaction kettle is greatly increased; and the production efficiency of the reaction kettle in the petrochemical enterprise is also improved observably.

Description

technical field [0001] The invention relates to the technical field of reactor equipment, in particular to an automatic flushing device for reactors in the petrochemical industry and a cleaning method thereof. Background technique [0002] At present, the cleaning of reaction kettles in my country's chemical enterprises is mainly carried out by manual hand-held spray guns, which takes a long time to clean and has dead spots for cleaning. Although some domestic chemical companies have adopted fully automatic cleaning equipment, they cannot realize closed cleaning of the reactor. Before the reaction kettle is cleaned, it is necessary to release the pressure and replace the harmful gas. When the harmful gas in the reaction kettle reaches the standard concentration, the kettle can be opened for cleaning, which increases the cleaning time. Moreover, the cleaning structure is complicated, and an additional power source is required for cleaning the lifting mechanism; the reaction ...

[0004] Chinese utility model patent (application number 201320001050.2, named "automatic cleaning device for chemical reaction kettle") and Chinese utility patent (application number 201520034033.8, named "automatic cleaning reaction kettle") both proposed solutions for automatic cleaning of reaction kettles scheme, but the automatic cleaning mechanism of the above scheme cannot realize the closed cleaning of the reactor, and the deoxygenation operation is still required for the reactor that needs to be deaerated before the reaction

The lifting mechanism of the nozzle in the above scheme needs pneumatic or electric as the power source, which increases the danger point in chemical enterprises
