Description

Technical Field

[0001] This utility model relates to the field of sodium hypochlorite production technology, specifically to a tail gas absorption tower for sodium hypochlorite production. Background Technology

[0002] Sodium hypochlorite (NaClO) is an inorganic compound widely used in disinfection, bleaching, and water treatment.

[0003] During the production of sodium hypochlorite, an absorption tower is required to absorb and treat the exhaust gas. However, the bottom of the absorption tower does not have a cleaning function, which causes waste to clump together on the inner wall of the absorption tower and fall off, resulting in blockage of the exhaust port. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a tail gas absorption tower for sodium hypochlorite production, which has the advantages of cleaning the inner cavity of the absorption tower and solving the problem that the bottom of the inner cavity of the absorption tower does not have a cleaning function.

[0005] This utility model discloses a tail gas absorption tower for sodium hypochlorite production, comprising an absorption tower body. A spray assembly is located at the top of the inner cavity of the absorption tower body, and a placement groove is formed at the bottom of the inner cavity. A cleaning assembly, including a motor, is located at the bottom of the placement groove. The motor's output end passes through the placement groove and extends into the inner cavity of the absorption tower body, where a rotating rod is located. A fixed rod is located on the right side of the rotating rod, and a scraper is located on the right side of the fixed rod, with the right side of the scraper in close contact with the inner wall of the absorption tower body. Movable plates are fixedly connected to the top and bottom of the left side of the fixed rod. Movable rods are rotatably connected to the left side of the inner cavities of the two movable plates. A cleaning roller is fixedly fitted onto the surface of the movable rod, and the surface of the cleaning roller is in close contact with the inner wall of the absorption tower body. A gear is fixedly fitted onto the top surface of the movable rod, and the surface of the gear meshes with annular teeth, with the surface of the annular teeth fixedly connected to the inner wall of the absorption tower body. An air inlet is located at the bottom of the left side of the absorption tower body, and an exhaust port is located at the top of the absorption tower body. The absorption tower body has a waste discharge port at the bottom of its front side. The exhaust gas is transmitted into the absorption tower body through the inlet, treated by a spray assembly, and then discharged through the outlet. When cleaning the bottom of the inner cavity of the absorption tower body is required, the motor first operates, driving a rotating rod to rotate. This rotating rod then drives a fixed rod and two movable plates to rotate. The movable plates then move a movable rod, which in turn moves a gear. A ring gear rotates the gear during its movement, which in turn rotates the movable rod. A screw then drives a cleaning roller to rotate, cleaning the inner wall of the absorption tower body. The rotating rod then moves a fixed rod, which in turn moves a scraper. The scraper removes the cleaned waste from the inner wall of the absorption tower body, which is then discharged through the waste discharge port. This prevents the absorption tower body from lacking a cleaning function, which could lead to waste clumping and blockage of the waste discharge port.

[0006] This invention relates to a tail gas absorption tower for sodium hypochlorite production. The spraying assembly includes a water pump located at the top left side of the absorption tower body. The water pump's input end is connected to a suction pipe, and its output end is connected to an outlet pipe. The outlet pipe extends through and into the inner cavity of the absorption tower body on its right side. Seven spray heads are equidistantly connected to the bottom of the outlet pipe. When tail gas needs to be sprayed, the present invention first transfers the treatment liquid to the water pump via the suction pipe, then to the outlet pipe, and finally to the spray heads. The spray heads then spray the treatment liquid into the absorption tower body to treat the waste gas.

[0007] The present invention relates to a tail gas absorption tower for sodium hypochlorite production, wherein both sides of the surface of the outlet pipe are fitted with limiting plates, and the top of the limiting plates is fixedly connected to the top of the inner cavity of the absorption tower body. The limiting plates can fix the outlet pipe, thus improving the performance of the outlet pipe during use and preventing the outlet pipe from shaking and causing unstable flow.

[0008] The present invention relates to a tail gas absorption tower for sodium hypochlorite production, wherein a fixing plate is fixedly connected to the bottom of the motor, and the inner cavity of the fixing plate is fixedly connected to the placement groove by fixing bolts. The fixing plate and fixing bolts can fix the motor, thus improving the motor's performance during use and preventing the motor from shaking and thus affecting its performance.

[0009] The present invention relates to a tail gas absorption tower for sodium hypochlorite production, wherein the right side of the fixing rod is fixedly connected to the scraper by a connecting block, and the right side of the fixing rod is located at the center of the left side of the scraper. The connecting block can fix the connection between the fixing rod and the scraper, thus improving the scraper's performance during use and preventing the scraper from becoming loose and falling off.

[0010] The present invention relates to a tail gas absorption tower for sodium hypochlorite production, wherein the inner cavity of the waste discharge port is provided with a valve body, and the rotating end of the valve body is provided with anti-slip particles.

[0011] The present invention relates to a tail gas absorption tower for sodium hypochlorite production, wherein the top of the exhaust port is provided with a connector, and the inner cavity of the connector is provided with six threaded holes at equal intervals.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, exhaust gas is transmitted to the main body of the absorption tower through the air inlet. The exhaust gas is treated by the spray assembly and discharged through the exhaust port. When it is necessary to clean the bottom of the inner cavity of the absorption tower, the motor first runs, which drives the rotating rod to rotate. The rotating rod drives the fixed rod and two movable plates to rotate. The movable plates drive the movable rod to move. The movable rod drives the gear to move. The ring gear can drive the gear to rotate during the movement of the gear. The gear drives the movable rod to rotate. The screw drives the cleaning roller to rotate. The cleaning roller cleans the inner wall of the absorption tower. The rotating rod drives the fixed rod to move. The fixed rod drives the scraper to move. The scraper can scrape off the cleaned waste on the inner wall of the absorption tower and discharge it through the exhaust port. This avoids the situation where the absorption tower does not have a cleaning function, which would cause the waste to clump on the inner wall of the absorption tower and fall off, causing blockage of the exhaust port.

[0014] 2. When the exhaust gas needs to be sprayed, the treatment liquid is first transferred to the water pump through the suction pipe, then transferred to the outlet pipe through the water pump, and finally transferred to the spray head through the outlet pipe. The spray head then sprays the treatment liquid into the main body of the absorption tower to treat the exhaust gas.

[0015] The limiting plate can fix the water outlet pipe, which makes the water outlet pipe work better and avoids shaking during use, thus preventing unstable water flow.

[0016] The motor can be fixed in place by using a fixing plate and fixing bolts, which makes the motor perform better during use and avoids the motor shaking during use, which would lead to poor motor performance.

[0017] The connecting block can fix the connection between the fixing rod and the scraper, which makes the scraper work better and prevents it from becoming loose and falling off during use. Attached Figure Description
