Description

Technical Field

[0001] This utility model relates to the technical field of dust removal equipment, and in particular to a wet dust removal equipment. Background Technology

[0002] Industrial production processes generate large amounts of dust, which cannot be directly released into the environment. Currently, to address this dust, Chinese patent CN220090917U discloses an integrated wet scrubber. This scrubber employs a two-stage dust removal process. The first stage uses a spray assembly to remove dust, followed by airflow introduced into the cylinder through an inlet. The second stage uses a filter screen to filter dust and particles from the airflow near the inlet. A cone-shaped structure maintains a dense airflow at the center of the cylinder, stabilizing the gas flow. A duct guides the gas flow, directing the filtered gas from the cylinder to the air guide assembly. However, the spray assembly structure of this wet scrubber is relatively simple, merely spraying, resulting in only moderate dust removal efficiency. Furthermore, the spray assembly lacks a water circulation system, leaving the sprayed water untreated and wasting water resources. Utility Model Content

[0021] Combination Figure 1 and Figure 2 As shown, this utility model provides a wet dust removal device, which includes: a cabinet 10 having an air inlet pipe, an air outlet pipe 120, and a processing chamber 130, the processing chamber 130 being connected to the air inlet pipe; a fan mechanism 20, which is disposed in the processing chamber 130 and connected to the air outlet pipe 120; a filter mechanism 30, which is disposed in the processing chamber 130; and a spray mechanism 40, which is disposed in the processing chamber 130. The spray mechanism 40 includes a first spray group 410, a second spray group 420, and a primary filter group 430. The first spray group 410 is located above the primary filter group 430, and the first spray group 410 sprays water mist downward toward the primary filter group 430. The second spray group 420 is located below the primary filter group 430, and the second spray group 420 sprays water mist upward toward the primary filter group 430.

[0022] Specifically, the wet dust removal equipment of this application needs to be used in conjunction with grinding or polishing equipment. The air inlet pipe is connected to the dust suction port of the grinding equipment. The fan mechanism 20 generates negative pressure airflow. The dust generated during the grinding process enters the air inlet pipe through the dust suction port under the action of the fan mechanism 20, and then enters the processing chamber 130. The first spray group 410 and the second spray group 420 work to generate water mist in two directions. That is, the first spray group 410 sprays water mist downward toward the primary filter group 430, and the second spray group 420 sprays water mist upward toward the primary filter group 430. The water mist generated by the second spray group 420 can intercept large dust particles that have just entered the treatment chamber 130. After the water mist combines with the dust, it falls downward to the outlet under the action of gravity. Some of the dust that is not intercepted continues to move upward under the action of wind, passing through the primary filter group 430 and entering the area above the primary filter group 430. Some of the dust is also intercepted by the primary filter group 430 when passing through it. The water mist generated by the first spray group 410 intercepts the dust. After the water mist combines with the dust, it falls downward to the upper side of the primary filter group 430 under the action of gravity. At this point, most of the large dust particles have been intercepted, while the small dust particles continue to move upward and are filtered by the filtration mechanism 30. The water mist from the two directions of this application can intercept dust in all directions, forming a multi-dimensional dust interception and improving dust removal efficiency; moreover, the second spray group 420 can continuously wash the lower surface of the first-stage filter group 430, avoiding dust accumulation on the lower surface of the first-stage filter group 430 and affecting the filtration efficiency.

[0023] It can be understood that the primary filter group 430 divides the spray zone 133 into upper and lower areas. The dust discharged from the air inlet pipe will be intercepted by the water mist sprayed by the second spray group 420, reducing the load on the primary filter group 430.

[0024] Furthermore, both the first spray group 410 and the second spray group 420 include multiple nozzles. The nozzles are atomizing nozzles, which can evenly atomize water into fine water droplets, increase the contact area with dust, and improve the dust removal effect.

[0025] In this embodiment, the processing chamber 130 is divided into a fan area 131, a filtration area 132, and a spray area 133, which are arranged from top to bottom. The fan area 131 is equipped with the fan mechanism 20, the filtration area 132 is equipped with the filtration mechanism 30, and the spray area 133 is equipped with the spray mechanism 40. The cabinet 10 is equipped with a first door 140, a second door 150, and a third door 160. The first door 140 corresponds to the fan area 131, the second door 150 corresponds to the filtration area 132, and the third door 160 corresponds to the spray area 133.

[0026] In actual operation, when the fan mechanism 20 needs inspection or maintenance, only the first door 140 needs to be opened to directly operate the fan mechanism 20 in the fan area 131, without the need for large-scale disassembly of the entire equipment, greatly improving maintenance efficiency. Similarly, when the filter mechanism 30 needs to be replaced or cleaned, the second door 150 can be opened to easily operate the filter area 132. For the adjustment or maintenance of the spray mechanism 40, only the third door 160 needs to be opened to perform the work in the spray area 133. This zoning design not only makes equipment maintenance more convenient but also improves the safety of equipment use, avoiding unnecessary interference or damage to other areas during maintenance.

[0027] Furthermore, the first door 140, the second door 150, and the third door 160 are all provided with a connecting side and a movable side. The connecting side is connected to the cabinet 10 via a hinge, and the movable side is connected to the cabinet 10 via a door lock. This design makes the doors more flexible and convenient to open and close. When it is necessary to operate the inside of the equipment, simply unlock the corresponding door and rotate the door around the hinge; the operation is simple and effortless. Moreover, the door lock effectively ensures the sealing and stability of the door when closed, preventing accidental opening during equipment operation and thus ensuring the safe operation of the equipment. At the same time, the hinges can withstand frequent opening and closing of the door, ensuring long-term reliability.

[0028] Furthermore, the third door 160 is provided with an observation window 161. The observation window 161 is made of high-strength transparent material, which has good light transmission and impact resistance. Through the observation window 161, the operator can directly see the operating status of the spray mechanism 40 in the spray area 133, and can conduct preliminary inspection and judgment without opening the door. Once an abnormality is found in the operation of the spray mechanism 40, it can be dealt with quickly, which is both convenient and safe.

[0029] Furthermore, the spray zone 133 is provided with a first bracket 1331, and the primary filter assembly 430 is detachably mounted on the first bracket 1331. The first bracket 1331 is fixedly mounted on the inner wall of the cabinet 10 and has a mounting groove; the primary filter assembly 430 is inserted into the mounting groove, and the two first brackets 1331 support the left and right sides of the primary filter assembly 430 respectively. When it is necessary to clean, replace or maintain the primary filter assembly 430, the operator can quickly and easily pull the primary filter assembly 430 out of the first bracket 1331 after opening the third door 160, complete the corresponding operation and then reinstall it, which greatly improves the maintenance efficiency of the equipment, reduces the downtime of the equipment and ensures the continuous and stable operation of the equipment.

[0030] Furthermore, the filtration mechanism 30 includes multiple secondary filter groups arranged longitudinally; the filtration zone 132 is provided with multiple second supports 1321, each corresponding to one of the secondary filter groups; the secondary filter groups are detachably mounted on the second supports 1321. Similarly, the second supports 1321 are fixed to the inner wall of the cabinet 10 and have mounting grooves; the secondary filter groups are inserted into the mounting grooves, which support the left and right sides of the secondary filter groups. When cleaning, replacement, or maintenance of the secondary filter groups is required, the operator can quickly and easily remove the secondary filter groups from the second supports 1321 after opening the second door 150, complete the corresponding operations, and then reinstall them, greatly improving the maintenance efficiency of the equipment, reducing downtime, and ensuring the continuous and stable operation of the equipment.

[0031] Furthermore, the two-stage filter groups with different filtration levels can be designed sequentially along the air intake direction to form a gradient filtration effect, which can gradually intercept dust particles of different sizes and improve the overall filtration accuracy.

[0032] In this embodiment, the cabinet 10 is further provided with a wastewater tank 50 and a water storage tank 60. The wastewater tank 50 is located below the treatment chamber 130 and is connected to the treatment chamber 130 through a water outlet. The water storage tank 60 is connected to the wastewater tank 50 through a grid. The water storage tank 60 is equipped with a water pump 70, which is connected to the first spray group 410 and the second spray group 420 through a water supply pipe. When the wet dust removal equipment is running, the wastewater generated in the treatment chamber 130 will flow into the wastewater tank 50 below through the water outlet for collection. The wastewater tank 50 can temporarily store wastewater to prevent wastewater from flowing freely and causing pollution to the surrounding environment. As the wastewater flows from the outlet into the wastewater tank 50, it will be filtered by the filter cartridge 820 below, leaving the dust in the filter cartridge 820. The water pump 70 installed in the water storage tank 60 will start during the operation of the equipment. It will transport the water in the water storage tank 60 to the first spray group 410 and the second spray group 420 through the water pipe, so as to provide water for the spray group and realize the spraying and settling operation of dust in the wet dust removal process, ensuring the normal operation of the equipment and good dust removal effect.

[0033] Furthermore, the outlet is equipped with a sewage treatment mechanism, which includes a separator 810 and a filter cartridge 820. The upper end of the separator 810 is detachably connected to the outlet, and the lower end of the separator 810 has an opening. The filter cartridge 820 is disposed inside the separator 810, and the upper end of the filter cartridge 820 is connected to the separator 810. The separator 810 allows sewage to pass through a relatively independent space before entering the sewage tank 50, facilitating preliminary treatment and guidance of the sewage. The filter cartridge 820 is designed to prevent shaking or displacement during sewage passage. When wastewater flows out of the outlet and enters the separator 810, it is filtered by the filter cartridge 820. The filter cartridge 820 can effectively intercept dust particles in the wastewater, allowing relatively clean water to flow into the wastewater tank 50 from the opening at the bottom of the separator 810, and then into the water storage tank 60, while the dust remains inside the filter cartridge 820. This not only improves the wastewater treatment effect, but also facilitates the subsequent centralized cleaning of dust, further enhancing the overall performance and ease of use of the wet dust collector.

[0034] Furthermore, the dust on the filter cartridge 820 can be cleaned by opening the third door 160 and removing the separator 810 and filter cartridge 820.

[0035] In this embodiment, the air inlet pipe includes a main air inlet pipe 111 and a secondary air inlet pipe 112. The main air inlet pipe 111 is mainly used to introduce the main dust-laden airflow, and its pipe diameter is relatively large to ensure sufficient airflow to enter the equipment for dust removal. The secondary air inlet pipe 112 plays an auxiliary role in air intake, and its pipe diameter is smaller than that of the main air inlet pipe 111. The air intake volume can be adjusted according to actual needs. By connecting and cooperating with different equipment through the main air inlet pipe 111 and the secondary air inlet pipe 112, it is possible to more flexibly realize the use of one wet cleaning equipment with multiple grinding or polishing equipment.
