Description

Technical Field

[0001] This utility model relates to the field of gas dust removal technology, and in particular to a wet dust removal fan device. Background Technology

[0002] In mineral processing, wet scrubbing fans are crucial equipment for improving the working environment and protecting the health of employees. Currently, these fans primarily rely on the suction generated by impeller rotation for dust removal. However, high concentrations of particulate matter in the gas continuously and extensively come into direct contact with the impeller and impeller shroud during the dust removal process. This extensive contact not only causes abnormal vibrations during fan operation, significantly reducing equipment stability, but also severely accelerates the wear rate of the impeller and shroud. Under current technology, severe mechanical vibration not only weakens dust removal efficiency but also significantly shortens the lifespan of core components, forcing maintenance personnel to replace the impeller assembly approximately every three months. This high-frequency maintenance significantly increases labor intensity and, due to frequent spare parts replacements, significantly drives up production costs, forming a technical bottleneck that restricts the long-term efficient operation of the equipment. Utility Model Content

The support cylinder is an overall cylindrical structure with openings at both ends. The bottom of the support cylinder is connected to the conical base, and a top cover is provided at the top open end of the support cylinder.

[0009] Based on the structure of the aforementioned wet dust removal fan device, a flow-blocking component is also provided inside the support cylinder; the position of the flow-blocking component is flush with the bottom position of the first air outlet.

[0010] Based on the structure of the above-mentioned wet dust removal fan device, the flow obstruction component specifically includes a flow obstruction disc and a flow obstruction plate; the flow obstruction plate is evenly spaced in multiple positions around the flow obstruction disc, so that the flow obstruction disc is located at the center of the support cylinder, and the flow obstruction plate is obliquely arranged between the flow obstruction plate and the inner sidewall of the support cylinder.

[0011] Based on the structure of the aforementioned wet dust removal fan device, the second dust collection section includes a spray box, a second air inlet, and a second air outlet; the bottom of the spray box is connected to the second air inlet, and the side of the spray box is connected to the second air outlet; the second air outlet has an overall arc-shaped structure, forming an arc-shaped connection channel between the spray box and the support cylinder; through holes are provided on both side plates of the spray box for the second spray section to pass through, and the second spray section is embedded in the spray box.

[0012] Based on the structure of the aforementioned wet dust removal fan device, the fan is mounted on a support platform.

[0027] Example 1

[0028] like Figures 1-5 As shown, this utility model provides a technical solution:

[0029] A wet dust removal fan device includes, but is not limited to, a first dust removal section 1, a second dust removal section 2, and a fan 3; the air inlet of the fan 3 is connected to the second dust removal section 2, the second dust removal section 2 is connected to the first dust removal section 1, the air inlet of the first dust removal section 1 is connected to the air duct to be dusted, and a spray section is provided in both the first dust removal section 1 and the second dust removal section 2.

[0030] Based on the above structure, the gas to be dusted enters the first dust suppression section 1 through the inlet pipe, where it undergoes a first dust suppression treatment via the spray section. The airflow is then transported to the second dust suppression section 2, where it undergoes a second dust suppression treatment via the spray section. Thus, after two spray treatments, only a very small portion of the gaseous particles is emitted into the air, with a concentration below the comprehensive emission standards for air pollutants, protecting the ecological environment. The main feature of this device is that after the gaseous particles generated during the mineral processing and crushing process undergo pre-treatment by the spray system, only a small portion of the gaseous particles enters the impeller shroud, reducing the contact area between the gaseous particles and the impeller shroud of the fan 3, effectively improving the service life of the impeller shroud. Furthermore, after secondary treatment in the dust removal chamber of the fan 3, the concentration of gaseous particles emitted into the air is significantly reduced, protecting the ecological environment.

[0031] As an example, the first dust suppression unit 1 may include a support cylinder 11, a conical base 12, a first spray unit 13, a first air inlet 14, and a first air outlet 15; the support cylinder 11 is a cylindrical structure with openings at both ends, the bottom of the support cylinder 11 is connected to the conical base 12, and a top cover 16 is provided at the top opening end of the support cylinder 11; the first air inlet 14 is located on the side wall of the support cylinder 11 near the conical base 12, and the first air outlet 15 is located on the side wall of the support cylinder 11 near the top cover 16; a through hole is provided on the top cover 16 for the first spray unit 13 to enter; a gravity flow pipe 17 is provided on the conical base 12, and a gate valve 18 is provided on the gravity flow pipe 17.

[0032] Based on the above structure, the gas enters the support cylinder 11 through the first air inlet 14, and then enters the second dust removal section 2 through the first air outlet 15. While in the support cylinder 11, the first spray section 13 starts spraying to perform preliminary spraying treatment on the gas. The liquid with dust is collected in the conical base 12 and finally discharged outward from the gravity flow pipe 17 as needed. The gate valve 18 is used to control the opening and closing of the gravity flow pipe 17.

[0033] As an example, a filter screen 19 is provided at the contact part between the support cylinder 11 and the conical base 12, and the filter screen 19 is densely covered with filter holes; the first air inlet 14 is a rectangular cavity structure, and the filter screen 19 is adapted to the bottom position of the first air inlet 14; a first maintenance part 110 is provided on the first air inlet 14.

[0034] Based on the above structure, by setting the filter screen 19, large impurities that may exist in the fan 3 can be filtered to prevent large impurities from entering the gravity flow pipe 17 and blocking it; at the same time, a first maintenance part 110 is set on the first air inlet 14 to perform maintenance on the filter screen 19 and the internal components of the support cylinder 11, reducing the difficulty of later maintenance.

[0035] As an example, one end of the first air inlet 14 is embedded in the support cylinder 11, and the other end of the first air inlet 14 is also provided with a reducing pipe 111; one end of the reducing pipe 111 is a rectangular connecting end, and the other end is a circular connecting end; the reducing pipe 111 is connected to the external air intake channel through the circular connecting end, and connected to the first air inlet 14 through the rectangular connecting end; support columns are provided in the circumferential position of the support cylinder 11.

[0036] Based on the above structure, the external air intake channel and the first air intake port 14 can be quickly and sealed together by the reducing pipe 111, reducing the difficulty of later installation; the support cylinder 11 is raised to a predetermined height by the support column, leaving space for the gravity flow pipe 17 and the gate valve 18.

[0037] As an example, a flow-blocking element 112 is also provided inside the support cylinder 11; the position of the flow-blocking element 112 is flush with the bottom position of the first air outlet 15.

[0038] The flow-blocking component 112 specifically includes a flow-blocking disk 113 and a flow-blocking plate 114; the flow-blocking plate 114 is evenly spaced around the flow-blocking disk 113, so that the flow-blocking disk 113 is located at the center of the support cylinder 11, and the flow-blocking plate 114 is obliquely disposed between the flow-blocking plate 114 and the inner wall of the support cylinder 11.

[0039] Based on the above structure, the gas can be blocked by setting the baffle plate 113, so that the airflow can only flow through the gap between the adjacent baffle plates 114. This can increase the residence time of the gas inside the support cylinder 11, so that the water sprayed by the first spray section 13 can fully combine with the dust particles in the airflow. Setting the baffle plate 114 obliquely can increase the blocking area of ​​the airflow and further achieve turbulence.

[0040] As an example, the second dust suppression unit 2 may include a spray box 21, a second air inlet 22, and a second air outlet 23; the bottom of the spray box 21 is connected to the second air inlet 22, and the side of the spray box 21 is connected to the second air outlet 23; the second air outlet 23 has an overall arc-shaped structure, which forms an arc-shaped connection channel between the spray box 21 and the support cylinder 11, and through holes for the second spray unit 25 to pass through are provided on both side plates of the spray box 21, and the second spray unit 25 is embedded in the spray box 21.

[0041] Based on the above structure, by setting the second air inlet 22 as an arc-shaped structure, the liquid generated by the second spray section 25 can flow into the support cylinder 11 and finally be deposited in the conical base 12. By setting the second spray section 25, the airflow can be dusted again and further purified. Finally, the airflow is delivered to the fan 3 and discharged outward.

[0042] As an example, the wind turbine 3 is mounted on the support platform 4. The support platform 4 provides support for the wind turbine 3 and also facilitates the maintenance of the wind turbine 3 in the future.

[0043] As an example, the ends of the first spray section 13 and the second spray section 25 are both equipped with rotating double-layer atomizing nozzles, which increase the water mist coverage area to 95%, reduce the escape of gaseous particles, and play an effective role in dust removal.

[0044] As an example, a second inspection port 24 is also provided on the spray box 21, which is directly opposite the second air outlet. The spray components inside the spray box 21 can be inspected and maintained through the second inspection port 24, reducing the difficulty of later maintenance.

[0045] The working principle of the modified fan 3 is as follows: First, the gas containing particulate matter generated during the production process in the workshop undergoes a first pretreatment through the cylinder spray 1. After the gas is introduced into the cylinder, water mist is evenly sprayed onto the gas through the spray device to form a water film. Most of the particulate matter settles at the bottom of the cylinder and is then discharged into the mineral processing sedimentation tank through the bottom gate valve 18. Then, a small portion of the gas particles after being treated by the cylinder spray passes through the impeller of fan 3 and undergoes a second spray treatment through the dust removal chamber of fan 3. The gas particles undergo a second sedimentation and are then discharged into the mineral processing sedimentation tank. After two spray treatments, only a very small portion of the gas particles are emitted into the air, and the content is lower than the comprehensive emission standard for air pollutants, thus protecting the ecological environment. The main feature of this device is that after the gas particles generated during the mineral processing and crushing process are pre-treated by the spraying of the cylinder, only a small portion of the gas particles enter the impeller shroud, which reduces the contact area between the gas particles and the impeller shroud of the fan 3, effectively improving the service life of the impeller shroud; after the gas particles are treated in the dust removal chamber of the fan 3, the gas content discharged into the air is greatly reduced, protecting the ecological environment.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
