Description

Technical Field

[0002] Organic silicon, or organic silicon compounds, refers to compounds containing Si-C bonds and at least one organic group directly connected to silicon atoms. Compounds that connect organic groups to silicon atoms through oxygen, sulfur, nitrogen, etc. are also usually considered organic silicon compounds. Among them, polysiloxanes with silicon-oxygen bonds as the skeleton are the most numerous, most deeply studied, and most widely used type of organic silicon compounds, accounting for more than 90% of the total usage. The hydrochloric acid generated during the production of organic silicon needs to be recovered.

[0003] For example, a hydrochloric acid recovery device for silicone production with the authorization announcement number "CN218924686U" starts the third motor while washing, so that the second rotating shaft drives the sealing plate to rotate, and drives the adsorption column to rotate in the second cylinder, so that the washing liquid is evenly sprayed to the adsorption column, so as to better wash away the hydrochloric acid, achieve good recovery effect, and reduce waste. However, the hydrochloric acid recovery device for silicone production requires three motors to be used simultaneously to move the adsorption column adsorbed with hydrochloric acid from the first cylinder to the second cylinder, which results in the steps of hydrochloric acid recovery being more complicated, which reduces the working efficiency of the hydrochloric acid recovery device. At the same time, the hydrochloric acid recovery device for silicone production can only clean the outward side of the adsorption column, and the inner side of the adsorption column is also attached with hydrochloric acid, but it cannot be effectively cleaned, which reduces the working quality of the hydrochloric acid recovery device.

[0027] Working principle:

[0028] When it is necessary to recycle the hydrochloric acid produced during the production of organosilicon:

[0029] Hydrochloric acid adsorption stage:

[0030] First, the raw material solution is fed into the adsorption barrel 9, and then the external power supply of the first motor 301 is connected, and the first motor 301 is started. The first motor 301 drives the reciprocating screw 302 to rotate, and the reciprocating screw 302 drives the rack 306 to move, and the reciprocating screw 406 drives the sealing plate 4 to move, and the sealing plate 4 drives the adsorption column 12 to move. After the adsorption column 12 moves to the upper end of the adsorption barrel 9, the first motor 301 stops working, and then the external power supply of the second motor 304 is connected, and the second motor 304 is started. The second motor 304 drives the gear 305 to rotate, and the gear 305 drives the rack 306 to move.

[0032] First, the cleaning liquid is sprayed onto the surface of the adsorption column 12 through multiple nozzles 507. Since the upper end of the adsorption column 12 is connected to the sealing plate 4 through a bearing, when the cleaning liquid sprayed by the nozzle 507 has a large force, the adsorption column 12 will rotate, so that the adsorption columns 12 in other directions can also be cleaned.
