Technical Field

[0001] This utility model belongs to the technical field of dust removal devices, specifically relating to an adhesion inhibition device for bag dust collectors. Background Technology

[0002] Baghouse dust collectors are commonly used equipment in the metallurgical industry, and their operation is crucial to production stability. This invention provides a baghouse dust collector adhesion suppression device and its usage method. Especially for dust with high sulfur content and strong adhesion, this device can effectively suppress the adhesion on the surface of the filter bags and the inner wall of the dust hopper, reducing the risk of spontaneous combustion of the filter bags during operation. Utility Model Content

[0003] This invention provides a bag filter dust collector adhesion suppression device, which aims to reduce the risk of spontaneous combustion of filter bags during operation.

[0004] Therefore, the present invention adopts the following technical solution: A baghouse dust collector adhesion suppression device includes a quartz powder storage bin, a feeding pipe, a quartz powder inlet valve, a single-point blowing chamber, a blowing air source pipe, a blowing air valve, a conveying pipe, and a baghouse dust collector inlet flue. The quartz powder storage bin is used to store quartz powder. The bottom of the quartz powder storage bin is connected to a vertical feed pipe. The feed pipe is equipped with a quartz powder feed valve to control the feed speed. The bottom end of the feed pipe is connected to a single-point blowing chamber. The left side of the single-point blowing chamber is connected to a horizontal conveying pipe. The head end of the conveying pipe is connected to the inlet flue of the bag dust collector. The right side of the single-point blowing cavity is connected to a horizontal blowing air source pipe. The blowing air source pipe extends into the single-point blowing cavity and its extension length is adjustable. The blowing air source pipe is coaxial with the conveying pipe and is equipped with a blowing air valve to control the air volume.

[0005] Furthermore, the feeding pipe and the single-point blowing cavity, as well as the conveying pipe and the single-point blowing cavity, are all connected by flanges.

[0006] The beneficial effects of this utility model are as follows: The device has a simple structure and is easy to operate and maintain. During the operation of the bag filter, the suspended quartz powder sprayed in mixes with the dust collected by the dust collector, washes away the adhesion on the surface of the filter bag, reduces the adhesion on the surface of the filter bag and inside the ash hopper, and improves the filtration efficiency of the bag filter. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of the structure of this utility model; In the diagram: 1-quartz powder storage bin, 2-feeding pipe, 3-quartz powder feed valve, 4-single-point blowing chamber, 5-blowing air source pipe, 6-blowing air valve, 7-conveying pipe, 8-bag dust collector inlet flue. Detailed Implementation

[0008] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figure 1 As shown, a bag filter dust collector adhesion suppression device includes a quartz powder storage bin 1, a feeding pipe 2, a quartz powder feeding valve 3, a single-point blowing chamber 4, a blowing air source pipe 5, a blowing air valve 6, a conveying pipe 7, and a bag filter dust collector inlet flue 8.

[0009] Quartz powder storage bin 1 is used to store quartz powder. The bottom of quartz powder storage bin 1 is connected to a vertical feed pipe 2. The feed pipe 2 is equipped with a quartz powder feed valve 3 to control the feed speed. The bottom end of the feed pipe 2 is connected to a single-point blowing chamber 4. The left side of the single-point blowing chamber 4 is connected to a horizontal conveying pipe 7. The head end of the conveying pipe 7 is connected to the inlet flue 8 of the bag dust collector.

[0010] A horizontal blowing air source pipe 5 is connected to the right side of the single-point blowing chamber 4. The blowing air source pipe 5 extends into the single-point blowing chamber 4 and its extension length is adjustable. The blowing air source pipe 5 is coaxial with the delivery pipe 7. The blowing air source pipe 5 is equipped with a blowing air valve 6 to control the air volume. The single-point blowing chamber 4 is made of cast iron. A flange interface is opened on the right side of the single-point blowing chamber 4. The blowing air source pipe 5 passes through the flange interface into the single-point blowing chamber 4. The flange interface is equipped with a tightening device, which can control the extension length of the blowing air source pipe 5.

[0011] The conveying air pressure is 0.3-0.6MPa. The feed pipe 2 and the single-point blowing chamber 4, and the conveying pipe 7 and the single-point blowing chamber 4 are all connected by flanges. The conveying pipe 7 is made of wear-resistant material.

[0012] The working principle of this utility model is as follows: By spraying quartz powder into the baghouse dust collector during operation, the powder enters the collector along with the filtered dust, effectively reducing adhesion to the filter bag surface. This is particularly effective in preventing high-sulfur, highly adhesive dust from adhering to the filter bag surface for extended periods, reducing adhesion to the inner wall of the dust collector hopper, and lowering the risk of spontaneous combustion of materials adhering to the filter bag surface and accumulated material in the hopper.

[0013] During the operation of the bag filter dust collector, by adjusting the opening of the quartz powder feed valve 3, the opening of the blowing air valve 6, and the insertion depth of the blowing air source pipe 5, continuous blowing of different quartz powder supply can be achieved, reducing the adhesion on the filter bag surface and the inner wall of the ash hopper.

[0014] The device has a simple structure and is easy to operate and maintain. During the operation of the bag filter, the suspended quartz powder sprayed in mixes with the dust collected by the dust collector, washes away the adhesion on the surface of the filter bag, reduces the adhesion on the surface of the filter bag and inside the ash hopper, and improves the filtration efficiency of the bag filter.
