Abstract

The invention discloses a reaction kettle which comprises a tank body and an upper cover connected to the tank body. A feeding inlet, a liquid inlet and a maintaining opening are formed in the upper cover, the tank body comprises a heating wall, a heating sleeve and a tank bottom connected to the bottom of the heating wall, a discharging outlet is formed in the tank bottom, and the heating sleevesleeves the heating wall; the reaction kettle further comprises a cleaning device, a left pipe inlet and a right pipe inlet are symmetrically arranged on the upper cover, and sealing covers are arranged at the left pipe inlet and the right pipe inlet; the heating wall is provided with at least three spiral heating concave rails allowing the cleaning device to be positioned and slide at equal intervals; according to the reaction kettle and the cleaning method thereof, the reaction kettle is cleaned through an upper track nozzle and a lower track nozzle on the cleaning device, meanwhile, the cleaning device rotates when lifted through the spiral heating concave rails, and the effect of cleaning different angles of the inner wall of the reaction kettle is achieved.

Description

technical field [0001] The invention belongs to the field of reaction kettles, and in particular relates to a reaction kettle and a cleaning method thereof. Background technique [0002] Reactor cleaning mainly includes chemical cleaning and mechanical cleaning: chemical cleaning of titanium reactor: first of all, it is necessary to know the scale components in the laboratory reactor equipment, and it is best to take samples for analysis. After determining the dirt components, do a test first, select a cleaning agent and pass the test to confirm that it will not cause corrosion to the metal of the equipment. Then set up a temporary circulation device on site to circulate the cleaning liquid in the equipment to wash away the dirt; mechanical cleaning of the titanium reactor: use a high-pressure cleaning laboratory reactor device to flush the dirt with high-pressure water through the nozzle. The two methods have their own advantages and disadvantages. Chemical cleaning requir...
