[0041] In recent years, with the growing demand for dust collector products in the global market, dust collectors have become one of the hottest environmental protection equipment. Dust collectors are mainly used to purify particulate dust. However, in some special production environments, such as the exhaust gas generated by coal-fired power plants and boilers, these exhaust gases have a certain amount of dust and humidity. It is used to remove particulate dust, acid mist, water vapor and other substances in the wet air, especially the wet flue gas in the exhaust dust. Dust collectors with dehumidification, heating and other functions are the most ideal dust removal equipment for treating this type of environmental air pollution.

[0042] Conventional dust collectors are mainly used to remove dust, particulate matter and other pollutants from the air, and isolate dust and pollutants from the air through filtering devices to purify the air. In production environments with severe humidity, traditional dust removal is prone to form dust lumps on the filter element, affecting the filtering effect and failing to achieve good dust removal and dehumidification effects. Therefore, the air after filtration and discharge still has corrosion and humidity effects on the environment.

[0043] In order to solve the above problems, the utility model proposes a dust collector 1000. Figures 1 to 4 This is a schematic structural diagram of an embodiment of a dust collector 1000 provided by the utility model.

[0044] Please refer to Figures 1 to 4 The utility model proposes a dust collector 1000, wherein an air circulation passage is formed in the vertical direction inside the shell 1 of the dust collector 1000, wherein an internal filter chamber 11 is arranged at the lower end of the shell 1, and an exhaust chamber 12 is arranged at the upper end of the shell 1, and a filter assembly and a drying assembly are arranged in the filter chamber 11 and the exhaust chamber 12, respectively. In order to ensure the continuous filtering effect of the entire device, the filter assembly includes not only a filter device, but also a cleaning device for cleaning the filtered material on the filter device. When in use, air first enters the filter chamber 11 from the lower end of the shell 1, and passes through The filter device filters the dust in the air and removes the acidic substances in the gas. The filtered air is introduced into the exhaust chamber 12, and is heated and dehumidified by the drying component in the exhaust chamber 12. The air is discharged after being fully dried, so as to ensure the dryness of the ambient air as much as possible. At the same time, when the filter material on the filter device is solidified on the filter device due to moisture, the cleaning device can clean the filter material in time, so as to ensure the filtering effect of the filter device, so that the entire device can achieve stable dust removal and dehumidification effects in a humid industrial environment.

[0045] In order to ensure that the air flows smoothly from the lower end of the shell 1 to the upper end of the shell 1, an air guide chamber 13 is provided in the shell 1, and the two ends of the air guide chamber 13 are respectively connected to the exhaust chamber 12 and the filter chamber 11. When the air guide device in the air guide chamber 13 is working, the air filtered by the filter device can be smoothly guided to the exhaust chamber 12 for drying, thereby increasing the filtering and drying effect of the entire device on the air.

[0046] In this embodiment, the air inlet 14 and the air outlet 15 on the shell 1 are respectively arranged at one side of the filter chamber 11 and the exhaust chamber 12. When the entire device is working, air directly enters the filter chamber 11 from the outside of the shell 1 for filtration. After the filtration is completed, the air is heated and heated by the drying component, and then directly discharged through the exhaust port 15 at the exhaust chamber 12. The structure is more compact, and the air treatment efficiency is also higher.

[0047] After the air is filtered by the filtering device, it is introduced into the dehumidification device 9 through the air guide device for dehumidification. It should be noted that the dehumidification device 9 adopts a semiconductor refrigeration dehumidification method, and actively draws the humid air in the enclosed space into the dehumidification air duct under the action of the fan. The water vapor in the air condenses into water after passing through the semiconductor refrigeration mechanism, and then is discharged from the cabinet through the water guide pipe, which can achieve a good dehumidification effect. The application of dehumidifying the ambient gas by the dehumidification device 9 is already relatively common. The use of the dehumidification device 9 for dehumidification, on the one hand, also avoids the traditional use of chemicals for dehumidification, which has the risk of causing harm to the environment and human body. Compared with other dehumidification methods, it is healthier and more environmentally friendly. In this embodiment, the gas containing moisture is introduced into the dehumidification device 9 for dehumidification. After dehumidification, the gas enters the heating chamber 122 through the opening 17 of the vertical partition 16 for heating. After the gas is fully heated by the heating plate 8 and the bellows in the heating chamber 122, the water vapor is further removed. At the same time, the heated gas is discharged, which is also conducive to reducing the ambient humidity.

[0048] A horizontal mounting plate 3 is provided in the filter cavity 11 to mount a plurality of filter cartridges 31 in the filter device. The plurality of filter cartridges 31 are vertically mounted on the mounting plate 3, and both ends thereof are connected to the cavities on the upper and lower sides of the mounting plate 3. The filter cartridge 31 preferably adopts a membrane-coated filter cartridge 31, which can purify acidic substances in the air. When in use, air enters the filter cartridge 31 from the lower outer side of the filter cartridge 31, and is introduced into the upper cavity of the filter cavity 11, thereby completing the dust removal and filtration of the air.

[0049] Considering that the contact-type cleaning device is inevitably not simple in structure, and after long-term use, the structural components are easily corroded in a humid and acidic environment, the cleaning device is set as a blowing device 4 in this embodiment, and the filter cartridge 31 is cleaned by using the blowing device 4, which is not only simpler and more compact in structure, but also easy to implement in the control process. Specifically, the multiple nozzles 41 of the blowing device 4 are respectively arranged above the multiple filter cartridges 31. When the blowing device 4 is working, high-speed gas will be sprayed through the multiple filter nozzles, thereby blowing away impurities adsorbed on the filter cartridge 31, so that the surface of the filter cartridge 31 remains clean, thereby having a good continuous filtering effect.

[0050] In this embodiment, the air guide device is set as a fan assembly 21. When the fan assembly 21 is working, it can introduce the air filtered by the filter cartridge 31 into the air guide cavity 13. A mounting frame 22 is provided on the mounting partition 2. The fan assembly 21 can be detachably installed on the mounting frame 22. In addition, a sealing plate 23 is provided on the end of the mounting plate 3 and the mounting partition 2 corresponding to the outside of the shell 1 to seal the cavity where the blowing device 4 is located. During the operation of the blowing device 4, the sealing of the corresponding cavity can be further guaranteed, thereby preventing the filtered material from being discharged from the shell 1 during the cleaning of the filter cartridge 31.

[0051] In order to collect the filtered materials cleaned from the filter cartridges 31 in a centralized manner, an inverted trapezoidal ash hopper 5 is provided below one downward end of the plurality of filter cartridges 31. The filtered materials dropped from the filter cartridges 31 pass through the ash hopper 5 and fall into a receiving box 51 at the end of the ash hopper 5 for collection. The receiving box 51 and the snap-fitting parts 52 at the ends of the ash hopper 5 are opened, and the receiving box 51 is pulled outward from one end of the ash hopper 5, so that the filtered materials inside the receiving box 51 can be collected and dumped in a centralized manner. At the same time, a plurality of rollers 511 are provided at the lower end of the receiving box 51 to support the end of the receiving box 51 and facilitate its pulling and pulling movement.

[0052] Corresponding to the filter chamber 11, the air guide chamber 13 and the exhaust chamber 12, a box door 6 rotatably connected to the shell 1 is provided on one side. The box door 6 at the corresponding position can be opened to inspect the interior. When the entire device is working, the box door 6 is fixed to the shell 1 by a locking member 61.

[0053] In addition, in order to ensure the safety of the entire device during operation, an explosion-proof component is provided on the outside of the shell 1. Specifically, the explosion-proof shell 7 in the explosion-proof component is installed on the outside of the shell 1, and a connection portion 71 is provided between the explosion-proof shell 7 and the filter chamber 11, allowing gas to flow unidirectionally from the filter chamber 11 to the explosion-proof shell 7. When a deflagration occurs inside the filter chamber 11, the internal air pressure increases, and the internal gas will flow unidirectionally through the connection portion 71 to the explosion-proof shell 7 for discharge, thereby providing explosion-proof protection for the entire device.

[0054] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
