Problems solved by technology

The two methods have their own advantages and disadvantages. Chemical cleaning requires less labor, short cleaning time, and thorough cleaning, but it may cause corrosion of laboratory reactor equipment; mechanical cleaning will not cause corrosion to equipment, and can effectively clean hard dirt, but it takes a long time , The labor intensity is high, and more cleaning dead angles are prone to appear, and the cleaning is very troublesome, and it is necessary to enter through the maintenance port to clean the dead angles, especially on the stirring device

Embodiment 1

[0031] like Figure 1 to Figure 5 Shown; A kind of reactor, comprises tank body 2 and the loam cake 1 that is connected on the tank body 2, described loam cake 1 is provided with feed port 11, liquid inlet port 13 and maintenance port 14, and described tank body 2. It includes a heating wall 22, a heating jacket 21 and a tank bottom connected to the bottom of the heating wall 22. The bottom of the tank is provided with a discharge port 17, and the heating jacket 21 is set on the heating wall 22; it also includes cleaning Device 3, the upper cover 1 is symmetrically provided with a left pipe inlet 12 and a right pipe inlet 15, and the left pipe inlet 12 and the right pipe inlet 15 are provided with a sealing cover; the heating wall 22, etc. There are at least three spiral heating concave rails 23 for positioning and sliding of the cleaning device 3; The ring 32 is arranged above the lower cleaning pipe ring 33, and the upper cleaning pipe ring 32 is provided with at least 3 un...

Embodiment 2

[0034]On the basis of Embodiment 1, the upper cover 1 is provided with at least one locking bolt 16, and the cleaning device 3 is locked by the locking bolt 16; the spraying direction of the upper track nozzle 35 forms an included angle with the horizontal line A and forms an angle B with the axis of the tank body 2, and the lower track nozzle 36 forms an angle C with the horizontal line, the angle A is from 5 degrees to 60 degrees, and the angle B is from 1 degree to 60 degrees. 5 degrees, the degree of the angle C is 45 degrees to 135 degrees; the lower cleaning pipe ring 33 is equidistantly provided with at least 20 lower trajectory nozzles 36, and the angle C of the lower trajectory nozzles 36 ranges from small to The larger ones increase in the same order; the upper cleaning tube ring 32 is equidistantly provided with at least 20 upper track nozzles 35, and the included angle A of the upper track nozzles 35 increases in equal order from small to large; the spiral heating c...

Embodiment 3

[0037] Adopt the cleaning method of the reactor of embodiment 2, comprise the following steps:

[0038] S1. Open the sealing covers on the left pipe inlet 12 and the right pipe inlet 15, respectively install hollow screws on the water inlet 34 of the lower circle and the water inlet 37 of the upper circle, and connect the two hollow screws to the high-pressure water pump through the high-pressure water pipe Control the switching switches of the two high-pressure water pipes through the three-way valve, adjust the pressure valves on the two high-pressure water pipes to control the pressure in the upper cleaning pipe ring 32 and the lower cleaning pipe ring 33; the upper cleaning pipe ring 32 and the lower cleaning pipe ring 33 The water pressure inside is controlled at 200MPa to 320MPa; to control the water pressure at 200MPa to 320MPa depends on the number of nozzles, and the number of nozzles is controlled at 20-40, too many nozzles will affect the water outlet speed.

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...
