Description

Technical fields:

[0001] This utility model relates to the field of calcium carbide production, specifically to a water supply system for a gas scrubbing tower. Background technology:

[0002] A scrubbing tower is a common gas treatment device that effectively removes harmful substances from waste gases generated during industrial production. It is widely used in industries such as chemical, pharmaceutical, and food processing, where scrubbing towers are extensively applied to waste gas treatment to ensure environmental safety and ecological protection during production processes.

[0003] To ensure the normal operation of the scrubbing tower, a new 200m... 3 Wastewater collection tank for gas scrubbing tower, 1 unit, 400m² 3 The cold water tanks are all located underground. The existing three gas scrubbing tower water pumps and control cabinets are reused and installed in the newly built pit to ensure normal water supply and drainage, thereby ensuring the normal operation of the water supply system.

[0004] However, during operation, the sewage collection tank serves as a wastewater transfer point. After a long period of sedimentation, the sediment accumulates at the bottom of the tank. The accumulation of sludge over a long period causes the water at the bottom to rise to the upper layer. The settled wastewater is then pumped to the treatment tank for recycling and reuse.

[0005] Every so often, the sludge in the sewage collection tank needs to be cleaned. The cleaning method usually involves directly inserting a sludge pump and suction pipe into the tank. While the tank is working, the operator injects a certain amount of water into it and then uses a stirring device or enters the tank manually to stir it. This ensures that the sludge at the bottom contains enough water and is mixed into a slurry, which is then convenient for the sludge pump to work. This results in a lot of equipment being needed, low work efficiency, and increased labor intensity for the operators. Utility Model Content:

[0006] The purpose of this utility model is to provide a water supply system for a gas scrubbing tower.

[0007] This utility model is implemented by the following technical solution:

[0008] A gas scrubbing tower water supply system includes a cold water tank, a circulating pump, a scrubbing tower, and a sewage collection tank. The output end of the cold water tank is fixedly connected to and communicates with the input end of the circulating pump. The output end of the circulating pump is fixedly connected to and communicates with the input end of the scrubbing tower. The output end of the scrubbing tower is fixedly connected to the input end of the sewage collection tank. A cleaning pipe, which is a T-shaped pipe, is fixedly connected to the bottom of the sewage collection tank. A cylinder is fixedly installed inside the cleaning pipe. A push rod is fixedly connected to the output end of the cylinder. A drive motor is fixedly installed at the top of the push rod. A water tank is fixedly installed at the output end of the drive motor. Two stirring rods, each hollow rod, are fixedly installed at the top of the water tank. Each stirring rod communicates with the water tank, and each stirring rod has a through hole at its end.

[0009] Preferably, a return pipe is fixedly connected to the center of the side wall of the sewage collection tank, and a screen is installed at the top of the sewage collection tank.

[0010] Preferably, a bracket is fixedly installed on one side of the cleaning pipe. The bracket is L-shaped, and a hydraulic cylinder and a push switch are fixedly installed on the bracket. The push switch is located below the hydraulic cylinder. An L-shaped transmission rod is attached to the output end of the hydraulic cylinder.

A sealing block is fixedly connected to one end of the L-shaped transmission rod, and a suction pipe is fixedly connected to the cleaning pipe.

[0011] The advantages of this invention are: the device is equipped with a drive motor and a stirring rod, which continuously rotates and sprays water to directly dilute the relatively dry sludge deposited at the bottom, thus eliminating the need for other auxiliary tools and achieving cleaning from the bottom. It is simple to operate, reduces labor intensity, and is equipped with a hydraulic cylinder and a push-button switch to automate sludge removal, thereby avoiding damage caused by the sludge pump running dry and reducing operating costs.

[0016] like Figures 1 to 3 As shown, a gas scrubbing tower water supply system includes a cold water tank 1, a circulating pump 2, a scrubbing tower 3, and a sewage collection tank 4. The output end of the cold water tank 1 is fixedly connected to and communicates with the input end of the circulating pump 2. The output end of the circulating pump 2 is fixedly connected to and communicates with the input end of the scrubbing tower 3. The output end of the scrubbing tower 3 is fixedly connected to the input end of the sewage collection tank 4. A cleaning pipe 5 is fixedly connected to the bottom end of the sewage collection tank 4. The cleaning pipe 5 is a T-shaped pipe. A cylinder 11 is fixedly installed inside the cleaning pipe 5. A push rod 10 is fixedly connected to the output end of the cylinder 11. A drive motor 6 is fixedly installed at the top end of the push rod 10. A water tank 7 is fixedly installed at the output end of the drive motor 6. Two stirring rods 8 are fixedly installed at the top end of the water tank 7. Each stirring rod 8 has... The stirring rods are hollow, and each stirring rod 8 is connected to the water tank 7. Each stirring rod 8 has a through hole 9 at its end. When cleaning is performed, the drive motor 6 is started, causing the water tank 7 and the stirring rods 8 to rotate. The water tank 7 is filled with water, and the pressure of the delivery pump causes the water to spray out through the through holes 9 on the stirring rods 8, thus diluting the mud while stirring. This allows the sludge deposited at the bottom to be mixed smoothly into an easily absorbable slurry. After stirring for a certain period of time (usually 10 minutes, but the exact time can be adjusted depending on the situation; it can be connected to the central control room and controlled by a PLC), the cylinder 11 is started to descend, allowing the slurry to be absorbed smoothly through the suction pipe 12 on the left side.

[0017] A return pipe is fixedly connected to the center of the side wall of the sewage collection tank 4, and a screen is installed at the top of the sewage collection tank 4.

[0018] A bracket 18 is fixedly installed on one side of the cleaning pipe 5. The bracket 18 is L-shaped, and a hydraulic cylinder 16 and a push switch 17 are fixedly installed on the bracket 18. The push switch 17 is located below the hydraulic cylinder 16. An L-shaped transmission rod 14 is attached to the output end of the hydraulic cylinder 16. One end of the L-shaped transmission rod 14 extends into the cleaning pipe 5 and is slidably connected to it. A spring 15 is sleeved on the L-shaped transmission rod 14 and is located inside the cleaning pipe 5. A sealing block 13 is fixedly connected to one end of the L-shaped transmission rod 14. A suction pipe 12 is fixedly connected to the cleaning pipe 5. Furthermore, when the drive motor 6 stops after the timed rotation is completed, the cylinder 11 descends, and the pressure of the mud inside will squeeze the spring 15. At this time, the hydraulic cylinder 16 is in the retracted and reset state. Thus, the L-shaped transmission rod 14 is subjected to pressure. The pump moves to the left, contacting the push switch 17 to activate the sludge pump, allowing for smooth sludge absorption. However, if the dry sludge above blocks the connection between the cleaning pipe 5 and the sewage collection tank 4, insufficient sludge material will cause the pressure to stop the push switch 17. Under the automatic control of the PLC, the hydraulic cylinder 16 extends, causing the L-shaped transmission rod 14 to reset to the right. After resetting to the initial position, the PLC-controlled cylinder 11 rises again, and the drive motor 6 restarts to perform stirring and dilution. After a timed operation, the cylinder descends again, allowing the diluted sludge to be absorbed again. This automated operation significantly reduces the workload of operators and improves work efficiency.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
