Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to an obliquely inserted filter cartridge dust collector. Background Art

[0002] A dust collector is a device that separates dust from flue gas. The performance of a dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life, and ease of operation and management of the dust collector are also important factors to consider its performance. Dust collectors are commonly used facilities in boilers and industrial production.

The dust collector barrel of the dust collector is provided with an outer box body, an inner box body, a box door, a first sound insulation cotton and a second sound insulation cotton, so that they can be used in conjunction with each other, on the one hand, the overall strength of the dust collector barrel is increased, and on the other hand, the noise generated by the motor of the dust collector when working can be well reduced, and the structural form of the box door and the box body connected and matched is adopted, which facilitates the disassembly and assembly of the parts in the dust collector, thereby facilitating the later maintenance of the parts, and well improving the use effect and practicality of the dust collector barrel of the dust collector.

[0004] However, during the operation of the existing oblique-insertion filter cartridge dust collector, after long-term use, a lot of dirt will adhere to the inside of the dust collector, which will affect the subsequent dust removal effect of the dust collector. In addition, in the process of cleaning the internal components of the dust collector, it is rather cumbersome to clean the internal components of the dust collector, which will greatly reduce the efficiency of the use of the dust collector.

[0005] Therefore, in view of the above problems, an oblique insertion filter cartridge dust collector is proposed. Utility Model Content

[0027] Furthermore, an air bag 6 is provided on one side of the filter cartridge 5 , an air bag automatic drainer 7 is provided below the air bag 6 , and an air outlet 8 is provided on one side of the box body 1 .

[0028] Furthermore, a material level switch 10 is provided on one side of the ash hopper 9 , a pneumatic percussion hammer 12 is provided on the surface of the ash hopper 9 , an ash discharge valve 13 is provided below the ash hopper 9 , and a pressure relief inspection door 15 is provided on the surface of the box body 1 .

[0029] Furthermore, a dust shield 4 is provided below the air inlet 3 to provide a buffer and abrasion resistance, thereby extending the service life of the filter cartridge 5 .

[0031] Furthermore, the filter cartridge 5 has a high purification efficiency, and the material of the filter cartridge 5 can be replaced to achieve different filtering accuracies, with a conventional 5um accuracy and a maximum accuracy of 0.3um.

[0032] The working principle of the utility model is: after the dust-containing gas enters the dust collector under the guidance of the fan, due to the sudden expansion of the airflow end surface and the effect of the airflow distribution plate, a part of the coarse dust particles in the airflow settle to the ash hopper 9 under the action of gravity and inertia, and the fine dust particles with small density enter the filter chamber. Through the comprehensive effects of Brownian diffusion and fiber interception, the dust is deposited on the filter material surface of the filter cartridge 5. The purified gas enters the clean air chamber and is discharged from the air outlet 8 through the fan. The resistance of the dust collector increases with the dust accumulation on the surface of the filter cartridge 5. When the resistance increases, it becomes larger. When the resistance reaches a certain set value, a high-speed and high-pressure airflow is ejected through the small hole of the blow pipe through the pulse valve of the back-blowing system to clean the dust. At this time, the opening and closing of the pulse valve is controlled by the program. When the pulse valve is opened, the compressed air in the air bag 6 is expanded through the venturi tube and evenly enters the filter cartridge 5, forming an instantaneous positive pressure inside the filter cartridge 5, generating huge vibrations, causing the dust deposited on the filter material to fall off and fall into the ash hopper 9. The collected dust is discharged into the ash bucket 14 through the ash unloading valve 13.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
