Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically a high-temperature resistant pulse bag dust collector. Background Technology

[0002] Pulse jet baghouse dust collectors are dry dust collection devices that filter particulate matter in dust-laden gas through filter bags and remove dust accumulated on the surface of the filter bags using pulse jet cleaning. They are widely used in industrial dust control, such as in the power, metallurgy, chemical, and building materials industries, and have the advantage of high dust removal efficiency.

[0003] A pulse-jet bag filter dust collector, with announcement number CN210171026U, features a vertical frame as its main body. A dust collection box is fixed within the frame, and a partition divides the dust collection box into a dust collection chamber. Dust collection bags are located inside the dust collection chamber. A conical air inlet hopper connects to the bottom of the dust collection box, and a cleaning chamber connects to the top. A pulse-jet blowing structure is installed inside the cleaning chamber, which is connected to an air outlet duct. An electric valve connects the cleaning chamber and the air outlet duct. The bottom opening of the dust collection bags is closed, and a dust collection hopper connects to the bottom of the air inlet hopper. This pulse-jet bag filter dust collector offers high dust removal efficiency, and the pulse-jet blowing structure removes dust from the surface of the filter bags after dust removal, ensuring that the dust removal efficiency of the dust collector does not decrease.

[0004] The pulse bag filter described above also has a problem: when the pulse bag filter is used, its filter bag is made of high-performance non-combustible material with a melting point higher than that of ordinary polymers. In actual use, the manufacturing cost of this material is high, which results in a limited range of applications for the dust collector. Utility Model Content

[0006] Given that the existing technology has the problem that the dust filter bag of the pulse bag dust collector is made of high-performance non-combustible material with a melting point higher than that of ordinary polymers, the production cost of this material is high in actual use, resulting in a limited scope of application for the dust collector.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0024] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0027] Example 1:

[0028] Please see Figures 1-2 This is the first embodiment of the present invention.

[0029] This embodiment provides a high-temperature resistant pulse bag filter, comprising:

[0030] A conical air inlet duct 1, a cooling mechanism 2 is provided on one side of the conical air inlet duct 1, an auxiliary mechanism 4 is provided on the inner side of the conical air inlet duct 1, and a heat dissipation mechanism 5 is provided on the side of the cooling mechanism 2;

[0031] The cooling mechanism 2 includes a water tank 21 disposed on one side of the conical air inlet duct 1. Hollow plates 22 are evenly arranged inside the water tank 21. A cavity 23 is opened inside the hollow plate 22. An air inlet pipe 24 is fixed at the center of one side of the water tank 21. An exhaust pipe 25 is fixed at the center of the other side of the water tank 21. One end of the exhaust pipe 25 is fixedly connected to the circumference of the conical air inlet duct 1. A dust removal equipment body 3 is disposed on the top side of the conical air inlet duct 1.

[0032] Specifically, the inner cavities 23 of the hollow plate 22 are interconnected, the exhaust pipe 25 is connected to the inner side of the conical air inlet 1, the air inlet pipe 24 passes through the water storage tank 21 and is connected to the inner cavity 23 of the hollow plate 22, and the exhaust pipe 25 passes through the water storage tank 21 and is connected to the inner cavity 23 of the hollow plate 22.

[0033] Furthermore, the structure of multiple hollow plates 22 allows air to fully contact the cooling water as it passes through the inner cavity 23 of the hollow plate 22, thereby reducing the temperature and improving the cooling effect.

[0034] During use, the conical air intake duct 1 draws in air through the exhaust pipe 25, thereby drawing in air through the air intake pipe 24 on one side of the water storage tank 21. The air then flows through the cavity 23 inside the hollow plate 22. At this time, the air comes into contact with the cooling water inside the water storage tank 21 through the hollow plate 22, thereby reducing the temperature. The cooled air is then transported to the inside of the conical air intake duct 1 through the exhaust pipe 25, where it mixes and comes into contact with the high-temperature dust, thereby reducing its temperature and preventing the dust filter bag from being damaged due to high temperature.

[0035] In summary, through the structure of the cooling mechanism 2 and the structure of the water tank 21 and its inner hollow plate 22, the air drawn in through the air intake pipe 24 can be cooled. Then, with the cooperation of the exhaust pipe 25, the cooled air is delivered to the inside of the conical air intake duct 1, so that the high-temperature dust inside can come into contact with it, thereby reducing the temperature of the high-temperature dust. This structure has a low cost and a wider range of applications.

[0036] Example 2:

[0037] Please see Figures 3-4 This is the second embodiment of the present utility model.

[0038] Specifically, the auxiliary mechanism 4 includes a water supply trough 41 opened inside the conical air inlet duct 1, a spiral blade 42 fixed inside the conical air inlet duct 1, a drain valve 43 fixed on the top circumferential surface of the conical air inlet duct 1, and a water inlet valve 44 fixed on the bottom circumferential surface of the conical air inlet duct 1. The drain valve 43 and the water inlet valve 44 are respectively connected to the water supply trough 41 inside the conical air inlet duct 1.

[0039] Furthermore, the structure of the spiral blades 42 can extend the distance between dust and air transport, thereby improving the cooling effect.

[0040] Specifically, the heat dissipation mechanism 5 includes a water spray pipe 51 fixed to the top of the inner side of the water storage tank 21, atomizing nozzles 52 evenly fixed on the bottom circumferential surface of the water spray pipe 51, a water pump 53 fixedly installed at the center of the side of the water storage tank 21, the input end of the water pump 53 is connected to the bottom of the inner side of the water storage tank 21 through the input pipe 54, the output end of the water pump 53 is fixed with an output pipe 55, one end of the water spray pipe 51 passes through the water storage tank 21 and is fixed with a conduit 56, and one end of the output pipe 55 is connected to the inner side of the conduit 56.

[0041] Furthermore, atomized water droplets are sprayed out through the atomizing nozzle 52, allowing them to adhere to the surface of the hollow plate 22. Through evaporation, the heat in the air is carried away, improving its cooling efficiency.

[0042] In use, the inlet valve 44 can be opened to connect it to the cooling water source, and cooling water can be supplied to the inside of the water tank 41. During the process of transporting high-temperature air or dust inside the spiral blades 42, it comes into contact with the inner surface of the conical air inlet 1, and the heat is transferred to the cooling water inside the water tank 41. Then, the heated cooling water is discharged from the drain valve 43 after the drain valve 43 is opened. The circulating cooling water assists in cooling the high-temperature dust. At the same time, the water pump 53 is turned on to draw out the liquid inside the water storage tank 21 and transport it to the inside of the conduit 56 through the output pipe 55, so that the cooling water is transported to the inside of the spray pipe 51 and sprayed out by the atomizing nozzle 52. This causes small water droplets to adhere to the surface of the hollow plate 22 and absorb the heat in the air inside the hollow plate 22 through evaporation, thereby improving the air cooling efficiency.

[0043] In summary, through the structure of the auxiliary mechanism 4 and the heat dissipation mechanism 5, the high-temperature dust and air can be transported a longer distance with the cooperation of the spiral blades 42 inside the conical air inlet duct 1, thereby transferring heat to the cooling water and reducing the temperature of the dust. At the same time, the water pump 53 drives the liquid inside the water storage tank 21 to circulate, cooling the air inside the hollow plate 22, improving the cooling efficiency of the device, and thus extending the service life of the dust removal equipment.
