Description

Technical Field

[0001] This utility model belongs to the field of flue gas filtration technology, specifically relating to a pulse bag flue gas dust removal system for unloading hoppers. Background Technology

[0002] The pulse jet baghouse dust collector is a new type of high-efficiency pulse jet baghouse dust collector that is an improvement on the original baghouse dust collector. In order to further improve the pulse jet baghouse dust collector, the modified pulse jet baghouse dust collector retains the advantages of high purification efficiency, large gas handling capacity, stable performance, convenient operation, long filter bag life and low maintenance workload. The dust collection box can filter the flue gas discharged from different working furnaces. An input pipe is installed at the air inlet of the dust collection box to simultaneously input multiple sets of flue gas into the dust collector.

[0003] Currently, when treating flue gas, the flue gas in the pipeline enters the dust collector stably under the action of the fan. However, there are some problems in actual use. Specifically, the flue gas contains a large number of particulate impurities. These particulate impurities slide on the inner wall of the pipeline during the transportation process. When the fan stops running, a large number of impurities remain in the pipeline, which affects the pipeline's own transportation effect. Utility Model Content

[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0006] The unloading hopper pulse bag filter system includes an air conveying pipe, a pulse bag filter, and a fan body. The air conveying pipe is installed at the inlet end of the pulse bag filter, and the fan body for absorbing flue gas is installed at the outlet end of the pulse bag filter. The air conveying pipe transports flue gas from multiple working furnaces.

[0007] As a preferred embodiment of this utility model, the conveying assembly consists of an outer shell, a fan, and a guide plate. The guide plate is installed at the end of the air conveying pipe, the outer shell is installed on the side of the guide plate, and the fan is installed inside the outer shell.

[0008] As a preferred embodiment of this utility model, multiple sets of the mating pipes are provided, and the multiple sets of mating pipes are symmetrically installed on both sides of the working furnace.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] 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.

[0024] 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 or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0025] Depend on Figure 1 and Figure 2 As shown, this is a schematic diagram of the structure of the unloading hopper pulse bag flue gas dust removal system in this embodiment. The flue gas dust removal system includes an air conveying pipe 2, a pulse bag dust collector 3, and a fan body 4. The air conveying pipe 2 is installed at the air inlet end of the pulse bag dust collector 3, and the fan body 4 for absorbing flue gas is installed at the air outlet end of the pulse bag dust collector 3. The air conveying pipe 2 is used to transport flue gas in multiple working furnaces 1, and a confluence mechanism 5 is installed on the air conveying pipe 2.

[0026] During operation, the flue gas generated by the working furnace 1 is fed into the gas supply pipe 2 through the pipeline. Then, with the cooperation of the gas supply pipe 2, the flue gas enters the pulse bag filter 3. The pulse bag filter 3 filters the particulate impurities in the flue gas. After that, the fan body 4 extracts the filtered flue gas, completing the dust removal operation of the flue gas.

[0027] From the appendix Figure 3As shown, this is a schematic diagram of the merging mechanism 5 in this embodiment. The merging mechanism 5 includes a mating pipe 51, a connecting pipe 52, a merging pipe 53, and a conveying assembly 54. The mating pipe 51 is installed at equal intervals on the side of the working furnace 1. The connecting pipe 52 is connected to the mating pipe 51. The end of the connecting pipe 52 is connected to the merging pipe 53. The merging pipe 53 is connected to the gas supply pipe 2. The end of the gas supply pipe 2 is equipped with a conveying assembly 54. The conveying assembly 54 consists of an outer shell, a fan, and a guide plate. The end of the gas supply pipe 2 is equipped with a guide plate. The outer shell is installed on the side of the guide plate. The fan is installed inside the outer shell.

[0028] During operation, the airflow flows inside the air delivery pipe 2 due to the operation of the fan. Due to the difference in air pressure between the air delivery pipe 2 and the confluence pipe 53, the gas discharged from the connecting pipe 51 flows steadily into the air delivery pipe 2 under pressure. Then, under the blowing of the fan, the flue gas steadily enters the pulse bag filter 3, which facilitates the subsequent dust removal treatment of the flue gas by the pulse bag filter 3.

[0029] From the appendix Figure 3 As shown, there are multiple sets of the connecting pipe 51, and the multiple sets of connecting pipe 51 are symmetrically installed on both sides of the working furnace 1. A control valve is installed at the connection between the connecting pipe 51 and the working furnace 1. During use, it is used to stably control the discharge and sealing of flue gas in the working furnace 1, which facilitates the stable operation of subsequent components.

[0030] From the appendix Figure 4 As shown, this is a structural schematic diagram of the separation mechanism 6 in this embodiment. It also includes the separation mechanism 6, which includes a mating block 61, a partition plate 62, a storage compartment 63, and a blocking horizontal plate 64. The mating blocks 61 are installed at equal intervals on the gas supply pipe 2. The mating blocks 61 are connected to the inside of the gas supply pipe 2. The partition plate 62 is fixedly installed inside the mating block 61. The storage compartment 63 is installed at the bottom opening of the mating block 61. There is a gap between the partition plate 62 and the top of the inner wall of the gas supply pipe 2. The bottom of the partition plate 62 enters into the mating block 61. The side walls of the gas supply pipe 2 and the mating block 61 are jointly equipped with blocking horizontal plates 64. There are two sets of blocking horizontal plates 64, and filter slots are opened on the blocking horizontal plates 64.

[0031] The gas flows stably within the gas supply pipe 2. Particulate impurities in the flue gas directly impact the separator plate 62. Due to the weight difference between the gas and the impurities, the impurities automatically fall into the mating block 61 and are stably received by the collection chamber 63. Meanwhile, the gas continues to flow through the gap between the separator plate 62 and the gas supply pipe 2, achieving the separation and screening of large-volume particulate impurities in the flue gas. The installation of the blocking plate 64 can block the impurities in the collection chamber 63, preventing them from flowing out with the flue gas and ensuring the overall stability of the separation mechanism 6.

[0032] From the appendix Figure 5 As shown, the storage compartment 63 is symmetrically threaded with threaded rods at its end. The threaded rods are threadedly connected to the mating block 61. During use, the storage compartment 63 can be quickly disassembled as a whole by using the threaded rods, making it convenient to process the impurities collected in the entire storage compartment 63 separately.

[0033] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
