Description

Technical Field

[0001] The present invention relates to the technical field of bag dust collectors, and specifically to a temperature reduction device for a bag dust collector used for high-temperature gas dust removal. Background Technique

[0002] A bag dust collector is a common environmental protection device that separates and filters dust-containing gas through a cloth bag. When used in the metallurgical production field, a large amount of high-temperature gas containing soot will be generated during the processing and production process. When performing environmental protection treatment on the high-temperature gas, it is necessary to cool the high-temperature gas first to avoid reducing the service life of the filter cloth bag or directly damaging it due to the high temperature gas;

[0003] The utility model with the publication number CN215692469U discloses a bag dust collector with a temperature reduction structure. The provided temperature reduction mechanism sprays water through a spray head to cool the inside of the dust removal box, avoiding the situation that the cloth bag inside the main body mechanism is damaged by high temperature due to excessive temperature. The provided dust blowing mechanism blows air through an air duct over the filtering device, so that the dust inside it enters the bottom of the main body mechanism for storage. At the same time, the dust collector filter element is fixed by sliding into the inside of the card slot from the upper end of the card slot through a clamping block, increasing its stability. When the above scheme is used, the temperature of the incoming air flow is reduced by installing a spray sprinkling mechanism at the air inlet pipe of the bag dust collector. Although this method has an effective temperature reduction effect, during its use, as the high temperature evaporates the water body, it is easy to cause the inside of the bag dust collector to be relatively humid, which may cause problems such as "bag sticking" that affect the separation and filtration. The method of installing an independent heat exchanger externally to cool the hot air flow is restricted by the operating state of the equipment. When the hot air flow enters the bag dust collector, there may still be a phenomenon of relatively high temperature, which poses certain potential hazards. Summary of the Invention

Detailed implementation mode

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to the attached Figure 1-16 , and the following technical solutions are provided in this application.

[0040] Embodiment 1: A cooling device for a bag filter for high-temperature gas flow dust removal, comprising:

[0041] The bag filter housing 1 is vertically arranged through a support frame. A collection bin 5 is provided at the lower end of the bag filter housing 1. An air inlet joint 2 and a discharge pipe 3 are respectively communicated and provided at the upper ends on both sides of the bag filter housing 1. An air receiver 4 is horizontally installed on one side of the bag filter housing 1. A cooling treatment box 6 is vertically provided on one side of the bag filter housing 1 near the air inlet joint 2. A bag mounting plate 7 is horizontally provided at the upper end inside the bag filter housing 1. One side of the bag mounting plate 7 is connected to the cooling treatment box 6. A through hole is communicated and opened on one side of the cooling treatment box 6 near the air inlet joint 2. A cooling contact seat 9 is vertically provided on one side of the through hole inside the cooling treatment box 6, and the inner peripheral diameter of the cooling contact seat 9 is the same as the diameter of the through hole. During use, the high-temperature gas flow containing dust enters the cooling treatment box 6 through the air inlet joint 2, and then flows to the lower part of the bag mounting plate 7 from below the cooling treatment box 6. A plurality of filter bags are installed on the bag mounting plate 7, and the gas flow is filtered after cooling through the filter bags. When the bags are blocked, high-pressure air is blown to the bags through the air receiver 4 for self-cleaning of the bags.

[0042] A diversion and cooling component is provided to directly cool the air flow entering the cooling treatment box 6. The diversion and cooling component is arranged on one side of the cooling treatment box 6 close to the air connection joint 2. The diversion and cooling component includes a cooling contact seat 9 and a diversion cover 11. A control seat 8 is arranged on the side of the cooling treatment box 6 away from the air connection joint 2. The lower end of the control seat 8 is higher than the upper end of the cloth bag mounting plate 7. A control shaft 10 is horizontally arranged at the center of one side of the diversion cover 11. The control shaft 10 is rotationally inserted into the control seat 8 through a bearing. Cooling diffusion grooves 13 and arc-shaped diversion grooves 12 are respectively formed on the opposite sides of the cooling contact seat 9 and the diversion cover 11. And the outer diameter of the outer edge of the arc-shaped diversion groove 12 is smaller than the outer diameter of the outer edge of the cooling diffusion groove 13. A first cooling cavity 19 is formed in the cooling contact seat 9. When the hot air flow enters the cooling treatment box 6, refrigerated air is continuously fed into the first cooling cavity 19. At this time, the air temperature on the inner peripheral side of the annular cooling contact seat 9 decreases. The hot air flow is preliminarily cooled when passing through. Then, after contacting the diversion cover 11, under the diversion action of the arc-shaped diversion groove 12, it flows back and rushes towards the cooling diffusion groove 13. Since the position of the cooling diffusion groove 13 also has a relatively cold contact surface under the action of the first cooling cavity 19, the air flow that has been preliminarily cooled is further cooled. Then, under the diversion action of the cooling diffusion groove 13, the air flow diffuses to the four sides. During the diffusion process, the disturbance between the air flows causes the air flows to mix and turbulize, strengthening the cooling effect;

[0043] In addition, under the turbulent flow action after the air flow contacts the diversion cover 11 and the cooling contact seat 9, the dust particles in the air flow collide with each other. The particles with larger size or the re-aggregated particles directly fall downward.

[0044] An enhanced cooling component is provided for further cooling of the hot air flow. The enhanced cooling component is horizontally arranged below the cooling contact seat 9 and the flow guide cover 11 in the cooling treatment box 6. The enhanced cooling component includes an enhanced cooling plate 27 and a plurality of cooling pipes 30. The plurality of cooling pipes 30 are respectively horizontally inserted into the enhanced cooling plate 27. At the upper ends of both sides in the cooling treatment box 6, blocking vertical plates 40 are vertically arranged. The enhanced cooling plate 27 is horizontally arranged between the two blocking vertical plates 40. On one side of the enhanced cooling plate 27 where the two blocking vertical plates 40 are located, circulating cold boxes 31 are provided. Cold source connection ports 36 are provided at the lower ends of the circulating cold boxes 31. A plurality of second cooling cavities 29 are horizontally penetrated and communicated with the two circulating cold boxes 31 in the enhanced cooling plate 27. Flow channels 28 are horizontally opened between adjacent two second cooling cavities 29 in the enhanced cooling plate 27. Sealing pipe grooves are horizontally penetrated and communicated with the two circulating cold boxes 31 at the centers of both sides in the flow channels 28. The cooling pipes 30 are horizontally placed in the flow channels 28 and inserted into the two sealing pipe grooves. Conical guiding surfaces are opened at the upper and lower ends of the flow channels 28 respectively through the enhanced cooling plate 27. When the airflow containing a certain amount of heat after being cooled by the cooling contact seat 9 flows downward, it flows to the lower part inside the bag filter housing 1 through the flow channels 28 of the enhanced cooling plate 27. When passing through the flow channels 28, the cooling pipes 30 and the second cooling cavities 29 send circulating refrigerated air flow through the two circulating cold boxes 31. At this time, the airflow passing through the flow channels 28 contacts the side walls of the cooling pipes 30 and the flow channels 28, and is intensively cooled by the relatively cold side walls of the flow channels 28 and the cooling pipes 30, so that the temperature of the airflow contacting the filter bags later is appropriate or not affected by the usage state of the external independent heat exchanger. When the airflow enters the bag filter housing 1, its own enhanced cooling treatment can be carried out;

[0045] In addition, the number of the enhanced cooling plates 27 provided can be designed as required according to the working conditions of use or the temperature range of the externally installed heat exchanger.

[0046] Embodiment 2: On the basis of Embodiment 1, a state maintaining component is provided to maintain the cooling state and effect of the cooling contact seat 9 and the enhanced cooling plate 27. The state maintaining component includes two first cleaning strips 16 and a plurality of rotating frames.

The rotating frame includes a self-rotating sleeve 33 and two support strips 35. A conical flow dividing seat 14 is provided in the center of the arc-shaped flow guiding groove 12 of the control shaft 10 and points to the cooling contact seat 9. A plurality of flow dividing fins 15 are symmetrically provided on the outer side surface of the conical flow dividing seat 14 and the inner side surface of the arc-shaped flow guiding groove 12. Two first cleaning strips 16 are respectively welded on one side of two of the flow dividing fins 15. One side of the first cleaning strip 16 is inserted into and contacts the cooling diffusion groove 13 of the cooling contact seat 9, and the shape of the cross section of the side of the first cleaning strip 16 inserted into the cooling diffusion groove 13 corresponds to that of the cooling diffusion groove 13. A second cleaning strip 17 is horizontally provided on one side of each of the first cleaning strips 16. One side of each of the two second cleaning strips 17 is welded to two of the flow dividing fins 15 respectively. One side of each of the two second cleaning strips 17 contacts the inner peripheral surface of the cooling contact seat 9 respectively, and a support piece 18 is welded between the two second cleaning strips 17. When the flow guiding cover 11 rotates, the inner peripheral surface of the cooling contact seat 9 and the cooling diffusion groove 13 can be scraped of surface-accumulated dust and dirt through the first cleaning strip 16 and the second cleaning strip 17, improving the efficient heat exchange of the cold source in the first cooling chamber 19 and realizing the efficient cooling of the high-temperature air flow.

[0047] A first gear groove is provided on one side of the control seat 8, and one side of the control shaft 10 is inserted into the first gear groove and is sleeved with a driven gear 20. A second gear groove is provided in the control seat 8 at the lower end of the first gear groove, and a control wheel groove 21 is provided on the side of the control seat 8 close to the second gear groove. A support shaft tube 23 is provided in the center of the control wheel groove 21, which passes through the second gear groove and the control seat 8. A synchronous sleeve is sleeved on the support shaft tube 23. The synchronous sleeve is placed in the second gear groove and the control wheel groove 21, and a control gear 24 and a toggle impeller 22 are respectively provided. One side of the control gear 24 is meshed with the driven gear 20, and one side of the air bag 4 is horizontally connected to the bag dust collector box 1 through the control valve.

When the air bag 4 delivers high-pressure gas to the high-pressure air supply pipe 37 through the control valve, the high-pressure gas flows in the first high-pressure gas groove 38. During this period, when passing through the control wheel groove 21, the impeller 22 and the control gear 24 are driven to rotate at high speed. Under the action of the gear ratio of the control gear 24 and the driven gear 20, the driven gear 20 drives the air guide cover 11 to rotate slowly, thereby cleaning and scraping the first cleaning strip 16 and the second cleaning strip 17. The thickness of the first cleaning strip 16 and the second cleaning strip 17 is the same as that of the diverter fin 15, and does not affect the airflow blowing to the arc guide groove 12.
