Description

Technical Field

[0001] The utility model relates to the technical field of hydrochloric acid recovery, in particular to a hydrochloric acid recovery device. Background Art

[0002] Hydrogen chloride is an important industrial chemical substance used in the manufacture of dyes, fragrances, medicines, various chlorides and corrosion inhibitors. In addition, high-purity hydrogen chloride gas is widely used in the electronics industry. Electronic-grade hydrogen chloride is mainly used in vapor polishing, epitaxy and etching processes in the microelectronics industry. It can also be used in metal smelting, optical communications and scientific research.

[0003] Since hydrochloric acid is highly volatile, the hydrogen chloride gas therein is easily volatilized. Therefore, hydrochloric acid recovery and regeneration is generally completed by heating in a water bath. The hydrochloric acid waste liquid is heated in a water bath to volatilize the hydrogen chloride gas therein, and the hydrogen chloride gas at the volatilization site is passed into water, and the hydrogen chloride gas is redissolved by dissolving in water, thereby forming a clean hydrochloric acid aqueous solution.

[0004] The existing patent (publication number: CN212559459U) discloses a hydrochloric acid recovery device, which relates to the technical field of hydrochloric acid recovery, including a device body, a gas outlet is opened on the top of the device body, a liquid inlet is penetrated on one side of the top of the device body, a liquid inlet and a first liquid outlet are respectively penetrated on the upper and lower sides of one side of the device body, and an gas inlet pipe is connected to the lower side of the other side of the device body. Through the diverter plate, the diverter trough and the absorption tube, the user first pours the liquid from the liquid inlet, and the liquid flows into the diverter plate after entering the interior of the device body. Multiple diverter troughs divert the liquid, and the liquid flows from the multiple diverter troughs into the absorption tube and enters the absorption tube to keep the liquid flow rate consistent. The gas enters from the bottom of the absorption tube and merges with the liquid, so that the gas and liquid can reach a better absorption state after adjustment. During the recovery process, cooling water is injected into the cavity through the liquid inlet to cool the absorption tube and improve the recovery effect of hydrochloric acid. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. After the hydrochloric acid recovery device has been used for a long time, the internal structure of the device is corroded and damaged. Traditional equipment is mostly cleaned by workers holding special cleaning devices. The cleaning process is time-consuming and labor-intensive, thereby greatly increasing the labor intensity of the workers; 2. The traditional cleaning mechanism has a multi-dimensional fixed structure, and the cleaning mechanism cannot be adjusted according to the needs of the user. When the size of the hydrochloric acid recovery device is too large, it is necessary to replace a different cleaning mechanism, thereby greatly reducing the practicability of the equipment.

[0023] In this embodiment, Figure 1 As shown, the housing assembly 1 includes a hydrochloric acid recovery device body 101 , support seats 102 are provided at the four corners of the bottom end of the hydrochloric acid recovery device body 101 , and a liquid outlet 103 is provided in the middle of the bottom end of the hydrochloric acid recovery device body 101 .

[0024] In this embodiment, Figure 2 As shown, the inner dimension of the slide groove 5 is consistent with the outer dimension of the slider 7, thereby increasing the stability of the moving block 6 during movement, thereby preventing the moving block 6 from rotating with the rotation of the screw rod 4 during movement.

[0025] In this embodiment, Figure 1 As shown, the central axis of the screw rod 4 is consistent with the central axis of the motor 3; the position of the cleaning brush 17 is reciprocated, thereby greatly improving the power effect.

[0026] In this embodiment, Figure 4 As shown, the two threaded blocks 13 and the guide rod 14 are set to be in sliding connection, which increases the stability of the threaded block 13 during movement and avoids the threaded block 13 from being offset or tilted during movement.

[0029] The use method and advantages of the utility model: When the hydrochloric acid recovery device is in use, the working process is as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, the hydrochloric acid recovery equipment body 101 is placed in a specified position through the support seat 102. When it is necessary to clean the impurities remaining inside the hydrochloric acid recovery equipment body 101, according to the user's needs, the bidirectional screw 12 is driven to rotate by the control rod, and the bidirectional screw 12 drives the two threaded blocks 13 to move in opposite directions with the cooperation of the guide rod 14. At this time, the two threaded blocks 13 drive the brush plate 16 and the cleaning brush 17 through the two connecting rods 15 to find that the angle changes, so that the edges of the two cleaning brushes 17 are in contact with the inner wall of the hydrochloric acid recovery equipment body 101, so that the distance between the cleaning brushes 17 can be adjusted according to the user's needs, which solves the problem that when the size of the hydrochloric acid recovery device is too large, different cleaning mechanisms need to be replaced. Then, the servo motor 9 drives the mounting plate 10 to rotate, and the mounting plate 10 drives the cleaning brush 17 to rotate, so as to clean the residual impurities inside the main body 101 of the hydrochloric acid recovery equipment, thereby solving the problem that when the device needs to be cleaned, the workers need to hold a special cleaning device to clean the main body 101 of the hydrochloric acid recovery equipment, thereby greatly reducing the labor intensity of the workers, and thus meeting the demand for hydrochloric acid recovery in hydrogen chloride gas. At this time, the motor 3 and the servo motor 9 are started by the controller to work, the servo motor 9 drives the screw rod 4 to rotate, and the screw rod 4 drives the moving block 6 to move in cooperation with the slide groove 5 and the slider 7. At this time, the moving block 6 drives the connecting block 8 and the servo motor 9 to move, so that the cleaning brush 17 performs reciprocating cleaning inside the main body 101 of the hydrochloric acid recovery equipment, thereby greatly improving the cleaning effect of the residual hydrogen chloride inside the main body 101 of the hydrochloric acid recovery equipment.
