Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a wet dust collector. Background Technology
[0002] A wet scrubber is a dust removal device that uses water film filtration technology. It is commonly used in industry. Existing wet scrubbers generally work by contacting water with gas containing particulate matter, causing the particles to be wetted, impacted, and captured.
[0003] However, existing wet scrubbers do not have a cleaning structure, so particulate matter can remain inside the scrubber during use. Over time, this accumulation can cause blockages and lead to scrubber malfunctions. Utility Model Content
[0004] The purpose of this utility model is to provide a wet dust collector that solves the problem that existing wet dust collectors do not have a cleaning structure, resulting in particulate matter remaining inside the dust collector during use, which can cause blockage and malfunction over time.
[0005] To achieve the above objectives, this utility model provides a wet dust collector, including a polishing machine and a washable dust removal mechanism. The washable dust removal mechanism includes an oil collection tank, a spray chamber, a wet tower, two induced draft fans, and a sedimentation net. The oil collection tank is fixedly connected to one side of the polishing machine, and the spray chamber is fixedly connected above the oil collection tank. The wet tower is disposed in the spray chamber and includes a sprayer, multiple atomizing nozzles, and two water curtain plates. The sprayer is disposed between the oil collection tank and the spray chamber, and the multiple atomizing nozzles are disposed on the sprayer. The two water curtain plates are fixedly connected to the spray chamber and are respectively located at the two output ends of the polishing machine. The two induced draft fans are fixedly connected to the spray chamber and are located above the multiple atomizing nozzles. The sedimentation net is slidably connected to the oil collection tank and is located below the spray chamber.
[0006] The sprayer includes a water pump, an inlet pipe, and a spraying device. The oil collection tank is equipped with a circulating water pool. The water pump is fixedly connected to the circulating water pool. The inlet pipe is fixedly connected to the water pump and the spraying chamber and communicates with the water pump. The spraying device is located at one end of the inlet pipe.
[0007] The spraying device includes a spray pipe and a water curtain pipe. The spray pipe is fixedly connected to the spray chamber, the water inlet pipe and a plurality of atomizing nozzles, and is in communication with the water inlet pipe and the plurality of atomizing nozzles. The water curtain pipe is fixedly connected to the spray chamber and the water inlet pipe, and is in communication with the water inlet pipe.
[0008] The washable dust removal mechanism also includes an electrical control system, which includes an electrical control box, a differential pressure gauge, an alarm light, and an explosion-proof light. The electrical control box is fixedly connected to the spray chamber and located above the polishing machine. The differential pressure gauge is fixedly connected to one side of the spray chamber.

[0009] The washable dust removal mechanism further includes two inspection doors and an air distribution screen. The two inspection doors are hinged to the spray chamber and are located above the two induced draft fans. The air distribution screen is fixedly connected to the spray chamber and is located on the side of the two inspection doors away from the polishing machine.
[0010] This utility model discloses a wet dust collector. When using the wet dust collector, the polishing machine, two induced draft fans, and the sprayer are activated. Particles generated by the polishing machine are attracted by the two induced draft fans and enter the spray chamber. Under the action of the sprayer, multiple atomizing nozzles spray water mist, humidifying the airborne particles and impacting them, causing the humidified particles to fall to the bottom of the spray chamber. Simultaneously, the water sprayed by the sprayer forms a water curtain under the action of two water curtain plates, cleaning the spray chamber. The water flow carries the fallen particles out of the spray chamber and into a sedimentation net, where the particles are intercepted. The water flow can continue to be used, preventing particle accumulation and blockage. The electrical control system can monitor and control the dust collector in real time and issue an alarm in case of malfunction. This avoids the problem of existing wet dust collectors lacking a cleaning structure, where particles remain inside during use, causing blockage and malfunction over time. This design achieves the effect of long-term normal operation of the dust collector. Attached Figure Description

[0019] This utility model provides a wet dust collector, comprising a polishing machine 1 and a washable dust collection mechanism. The washable dust collection mechanism includes an oil collection tank 2, a spray chamber 3, a wet tower 4, two induced draft fans 5, a sedimentation net 6, an electrical control system 7, two inspection doors 20, and an air distribution net 21. The wet tower 4 includes a sprayer 8, multiple atomizing nozzles 9, and two water curtain plates 10. The sprayer 8 includes a water pump 11, a water inlet pipe 12, and a spraying device 13. The spraying device 13 includes a spraying pipe 14 and a water curtain pipe 15. The electrical control system 7 includes an electrical control box 16, a differential pressure gauge 17, an alarm light 18, and an explosion-proof light 19. The aforementioned solution solves the problem that existing wet dust collectors do not have a cleaning structure, resulting in particulate matter residue inside the dust collector during use, which accumulates over time and causes blockage, leading to dust collector malfunction.
[0020] In this specific embodiment, the oil collection tank 2 is fixedly connected to one side of the polishing machine 1, the spray chamber 3 is fixedly connected above the oil collection tank 2, the wet tower 4 is disposed inside the spray chamber 3, the sprayer 8 is disposed inside the oil collection tank 2 and the spray chamber 3, multiple atomizing nozzles 9 are disposed on the sprayer 8, two water curtain plates 10 are fixedly connected to the spray chamber 3 and are respectively located at the two output ends of the polishing machine 1, two induced draft fans 5 are fixedly connected to the spray chamber 3 and are located above the multiple atomizing nozzles 9, and the sedimentation net 6 is slidably connected to the oil collection tank 2 and is located below the spray chamber 3, using wet dust removal. When the polishing machine 1, the two blowers 5, and the sprayer 8 are started, the particles generated by the polishing machine 1 are attracted by the two blowers 5 and enter the spray chamber 3. Under the action of the sprayer 8, multiple atomizing nozzles 9 spray water mist, which humidifies the particles in the air and impacts them, causing the humidified particles to fall to the bottom of the spray chamber 3. At the same time, the water sprayed by the sprayer forms a water curtain under the action of the two water curtain plates 10, which cleans the spray chamber 3. The water flow carries the fallen particles out of the spray chamber 3 and into the sedimentation net 6. The particles are intercepted in the sedimentation net 6, and the water flow can continue to be used.
[0021] The oil collection tank 2 is equipped with a circulating water pool 22. The water pump 11 is fixedly connected to the circulating water pool 22. The water inlet pipe 12 is fixedly connected to the water pump 11 and the spray chamber 3 and communicates with the water pump 11. The spray device 13 is located at one end of the water inlet pipe 12. When using the sprayer 8, the water pump 11 draws water from the circulating water pool 22 into the spray device 13 for use.
[0022] Secondly, the spray pipe 14 is fixedly connected to the spray chamber 3, the water inlet pipe 12, and the plurality of atomizing nozzles 9, and communicates with the water inlet pipe 12 and the plurality of atomizing nozzles 9. The water curtain pipe 15 is fixedly connected to the spray chamber 3 and the water inlet pipe 12, and communicates with the water inlet pipe 12. When the water pump 11 is working, it pumps the water in the circulating water tank 22 into the water inlet pipe 12, and then sprays it out from the plurality of atomizing nozzles 9 on the spray pipe to humidify and impact the particulate matter in the air. At that time, some water flows into the water curtain pipe 15 from the water inlet pipe 12 and flows out from both ends of the water curtain pipe 15. With the cooperation of the two water curtain plates 10, a water curtain is formed to clean the inside of the spray chamber 3 and carry out the particles located at the bottom of the spray chamber 3 out of the spray chamber 3 and into the sedimentation net 6, thereby cleaning the inside of the spray chamber 3 and preventing the dust collector from clogging. The particles will be intercepted by the sedimentation net 6, and the water in the circulating water tank 22 can continue to be used by the water pump 11.
[0023] Meanwhile, the electrical control box 16 is fixedly connected to the spray chamber 3 and located above the polishing machine 1. The differential pressure gauge 17 is fixedly connected to one side of the spray chamber 3. The alarm light 18 is fixedly connected to the top of the spray chamber 3. The explosion-proof light 19 is fixedly connected to the spray chamber 3 and located above the polishing machine 1. When using the dust collector, the worker can adjust and control the entire dust collector through the electrical control box 16. The explosion-proof light 19 can provide safe and reliable illumination for the polishing machine 1 and prevent sparks from causing an explosion. The differential pressure gauge 17 will monitor the pressure difference inside and outside the spray chamber 3 in real time. If the set value is reached, the alarm light will light up, prompting the worker to stop work and adjust before use.
[0024] Finally, the two inspection doors 20 are hinged to the spray chamber 3 and are respectively located above the two exhaust fans 5. The air distribution net 21 is fixedly connected to the spray chamber 3 and is located on the side of the two inspection doors 20 away from the polishing machine 1. When the two exhaust fans 5 are working, the air distribution net 21 can guide the direction and speed of the air generated by the two exhaust fans 5 and make the exhaust air more uniform. When the exhaust fans 5 and other components in the spray chamber 3 need to be repaired, the two inspection doors 20 can be opened for repair.
[0025] When using a wet scrubber, the polishing machine 1, the two exhaust fans 5, and the water pump 11 are started. Particles generated by the polishing machine 1 are attracted by the two exhaust fans 5 and enter the spray chamber 3. Under the action of the water pump 11, water from the circulating water tank 22 enters the inlet pipe 12 and is then sprayed out from multiple atomizing nozzles 9 on the spray pipe, humidifying and impacting the airborne particles. Simultaneously, some water flows from the inlet pipe 12 into the water curtain pipe 15 and flows out from both ends of the water curtain pipe 15, forming a water curtain with the cooperation of the two water curtain plates 10. This water curtain cleans the inside of the spray chamber 3 and carries out particles located at the bottom of the spray chamber 3, into the sedimentation net 6, thus cleaning the inside of the spray chamber 3 and preventing dust collector blockage. The particles are intercepted by the sedimentation net 6, and the water in the circulating water tank 22 can continue to supply the water pump 11. The dust collector is designed to prevent particulate matter from accumulating and causing blockages. When using the dust collector, workers can adjust and control the entire dust collector through the electrical control box 16. The explosion-proof light 19 provides safe and reliable illumination for the polishing machine 1 and prevents sparks from causing an explosion. The differential pressure gauge 17 monitors the pressure difference inside and outside the spray chamber 3 in real time. If the set value is reached, the alarm light will illuminate, prompting workers to stop work and adjust the settings before use. When the two induced draft fans 5 are working, the air distribution net 21 guides the airflow direction and speed generated by the two fans 5, making the exhaust air more uniform. When the induced draft fans 5 and other components inside the spray chamber 3 need maintenance, the two maintenance doors 20 can be opened for maintenance. This avoids the problem of existing wet dust collectors lacking a cleaning structure, where particulate matter remains inside during use, causing blockages and malfunctions over time. This ensures the dust collector can operate normally for extended periods.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
