A combined pulse dust suppressor Technical Field
[0001] This utility model relates to the technical field of pulse dust removal devices, specifically a combined pulse dust collector. Background Technology
[0002] With the rapid development of modern industrial production, various industrial dust pollution problems have become increasingly prominent, posing a severe challenge to environmental protection and occupational health. In the production processes of industries such as metallurgy, building materials, chemicals, and power, large amounts of dust-laden gases are generated. If these gases are emitted directly without effective treatment, they will not only cause air pollution but also harm the health of operators. Therefore, efficient and reliable dust removal equipment has become an indispensable environmental protection device in industrial production. Traditional baghouse dust collectors use an integrated structure; when some filter bags are damaged or clogged, the machine must be shut down for maintenance, affecting production efficiency.
[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Summary of the Invention

[0005] Each of the aforementioned filter structures includes an outer casing, a filter element installed on the inner top surface of the outer casing, the filter element including a flange ring and a filter bag, the filter bag being disposed on the flange ring, the flange ring being installed on the center of the inner top surface of the outer casing, an air outlet pipe being inserted into the center of the upper wall of the outer casing, a detection box being installed at one end of the air outlet pipe, an air quality sensor being installed on the inner wall of the detection box, a ventilation pipe being inserted into the detection box, an air outlet valve being provided at one end of the ventilation pipe, and a debris discharge valve being provided at the lower end of the outer casing;

[0011] Preferably, the outer casing is provided with an inspection door.
[0012] Beneficial effects
[0013] This utility model provides a combined pulse dust collector, which has the following advantages compared with the prior art: Dust-laden gas passes through the filter bag, and the dust is trapped on the outer surface of the filter bag. The purified gas enters the detection chamber through the exhaust pipe, and the gas cleanliness is monitored in real time by an air quality sensor. Once one or more air quality sensors in the multiple filter structures detect that the quality of the discharged gas is poor, the corresponding inlet valve and outlet valve are closed to isolate the filter structure from the device, preventing the continued discharge of polluted gas, while not affecting the normal dust removal work of other filter structures.

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.
[0021] Please refer to Figure 1-4. In order to solve the problem that traditional baghouse dust collectors adopt an integral structure, and when some filter bags are damaged or blocked, the machine must be stopped for maintenance, which affects production efficiency, this technical solution is designed. The detailed technical solution is as follows.
[0022] A combined pulse dust suppressor includes two legs 1, with multiple filter structures installed on the two legs 1. The multiple filter structures are equipped with an air inlet structure, an air outlet structure, and a pulse blowing structure.
[0023] Specifically, each filter structure includes an outer casing 2, a filter element installed on the inner top surface of the outer casing 2, the filter element including a flange ring 3 and a filter bag 4, the filter bag 4 is set on the flange ring 3, the flange ring 3 is installed on the center part of the inner top surface of the outer casing 2, an air outlet pipe 5 is inserted on the center part of the upper wall of the outer casing 2, a detection box 6 is installed at one end of the air outlet pipe 5, an air quality sensor 7 is installed on the inner wall of the detection box 6, a ventilation pipe 8 is inserted on the detection box 6, an air outlet valve 9 is set at one end of the ventilation pipe 8, and a waste discharge valve 10 is set at the lower end of the outer casing 2;
[0024] Specifically, the air intake structure includes an air intake valve 11 installed on each outer casing 2, and an air intake manifold 12 is installed at one end of the air intake valve 11;
[0025] Specifically, the exhaust structure includes an exhaust manifold 13, and an exhaust pump 14 is installed at one end of the exhaust manifold 13;
[0026] It should be noted that the dust-laden gas is distributed to the inlet valves 11 of each outer casing 2 through the main inlet pipe 12, enters the outer casing 2, passes through the filter bags 4, and the dust is trapped on the outer surface of the filter bags 4. The purified gas rises through the inside of the filter bags 4 to the outlet pipe 5, and enters the detection chamber 6 through the outlet pipe 5. The air quality sensor 7 monitors the cleanliness of the gas in real time. Then, it flows through the ventilation pipe 8 and the outlet valve 9 into the main outlet pipe 13. Finally, the clean gas is discharged from the device by the exhaust pump 14 to prevent the direct discharge of dusty gas. The exhaust pump 14 works to assist the gas flow inside the device. Once one or more air quality sensors 7 in the multiple filter structures detect that the quality of the discharged gas is poor, the corresponding inlet valve 11 and outlet valve 9 are closed to isolate the filter structure from the device, preventing the continued discharge of polluted gas, while not affecting the normal dust removal work of other filter structures.
[0027] Specifically, the pulse blowing structure includes a pulse valve 15 disposed on the side wall of each ventilation duct 8, a blowing duct 16 disposed on the pulse valve 15, and an air bag 17 disposed at one end of the blowing duct 16.
[0028] It should be noted that the blowing pipe 16 is located at the air inlet of the pulse valve 15 and is connected to the air tank 17. When the pulse valve 15 on the isolated filter structure is working, high-pressure compressed air is sprayed from the air tank 17 through the blowing pipe 16 and the pulse valve 15 into the filter element. The high-pressure airflow causes the filter bag to expand rapidly, shaking off the dust layer attached to the surface. The detached dust falls into the bottom of the outer box 2. The dust cleaning process can be continuously sprayed 3 to 5 times to ensure that the dust on the filter bag 4 is completely removed. After the dust cleaning is completed, the air inlet valve 11 and the air outlet valve 9 of the filter structure are briefly opened to allow the gas to flow through the filter element and enter the detection box 6. The air quality sensor 7 monitors the exhaust gas in real time. If it still does not meet the standard, it is determined that the filter bag is damaged or the seal is ineffective, and manual repair is required. The dust detached during the dust cleaning is periodically discharged through the discharge valve 10 at the bottom of the outer box 2 to avoid secondary dust.
[0029] As a preferred and further option, a control panel 18 is mounted on one of the two legs 1; the control panel 18 usually has a built-in microcontroller, which can be programmed into software to control the device by writing a control program. Since this is existing technology, it will not be described in detail here.
[0030] As a preferred and further option, a sealing gasket 19 is provided between the flange ring 3 and the outer casing 2, and a bolt 20 is movably inserted into the flange ring 3. The bolt 20 passes through the sealing gasket 19 and is then threaded into the outer casing 2.
[0031] As a preferred and further option, the outer casing 2 is provided with an inspection door 21;
[0032] If the filter element needs to be replaced, the operator can remove the flange ring 3 bolts 20 through the inspection door 21 and replace the filter element with a new one. The sealing gasket 19 is used to improve the sealing quality between the flange ring 3 and the outer casing 2.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
