Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, and in particular to a bag filter for removing black smoke. Background Technology

[0002] Baghouse dust collectors are commonly used industrial dust removal equipment, primarily used to capture solid particles (such as dust and smoke) in airflow. They separate airborne particles through the filtration action of filter bags, achieving the purpose of purifying the air and reducing pollution.

[0003] Baghouse dust collectors purify the black smoke generated by incomplete combustion during use. Since the black smoke contains a large amount of oily and sticky particles, these particles are more likely to adhere to the filter bags at high temperatures, requiring more frequent cleaning operations. Although increasing the cleaning frequency can maintain the normal operation of the filter bags, it will lead to accelerated wear of the filter bags and shorten their service life. Utility Model Content

[0004] The main purpose of this invention is to provide a bag filter for removing black smoke.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A baghouse dust collector for removing black smoke includes a body. A connecting pipe is installed on the lower side of the body. One end of the connecting pipe is connected to a frame. One end of the frame is connected to an air inlet pipe. A cooling mechanism is fixed inside the frame. The cooling mechanism includes flow dividers symmetrically installed at the top and bottom ends of the frame. A guide pipe connects the flow dividers. An air inlet is installed at the top of the upper flow divider, and an air outlet is fixed at the bottom of the lower flow divider.

[0007] Preferably, a dust removal mechanism is fixed inside the machine body. The dust removal mechanism includes a mounting plate fixed inside the machine body, and multiple sets of filter bags are installed at equal intervals on the mounting plate.

[0008] Preferably, a backflush mechanism is provided on one side of the top of the machine body, and the backflush mechanism includes an air bag, an electromagnetic pulse valve, an air guide pipe and a nozzle.

[0009] Preferably, the air bag is fixed to the outside of the machine body, and the electromagnetic pulse valve is connected to the air bag pipeline.

[0010] Preferably, the air guide tube is connected to the electromagnetic pulse valve clamp, and the air guide tube extends into the body of the machine.

[0011] Preferably, the nozzle is threadedly connected to the air guide pipe, and the number of nozzles is the same as the number of filter bags, and their positions correspond to each other.

[0012] Preferably, an exhaust pipe is installed on the upper side of one side of the machine body, and a drain outlet is provided at the bottom of the machine body.

[0013] The beneficial effects of this technology are:

[0014] By setting up a frame and a cooling mechanism, the cooling mechanism can be fixed inside the frame. Before the black smoke enters the machine body, it first enters the frame. At this time, the air inlet in the cooling mechanism is connected to the external air supply mechanism. The cooling gas enters the distributor frame through the air inlet and is evenly guided to each guide pipe. The black smoke comes into contact with the guide pipe during its flow, which can effectively cool it down. The used cooling gas is discharged through the air outlet. Cooling the black smoke can prevent excessive oily substances from adhering to the surface of the filter bag due to high temperature, thereby reducing the need for dust cleaning, avoiding accelerated wear of the filter bag, and improving its service life.

[0020] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0021] like Figures 1-3As shown, the bag filter dust collector for removing black smoke provided in this embodiment includes a body 1. A connecting pipe 2 is installed on the lower side of the body 1. The connecting pipe 2 can connect the frame 3 and the body 1. One end of the connecting pipe 2 is connected to the frame 3. The frame 3 can support the cooling mechanism 5. One end of the frame 3 is connected to the air inlet pipe 4. Black smoke enters the frame 3 through the air inlet pipe 4. The cooling mechanism 5 is fixed inside the frame 3. The cooling mechanism 5 includes a diverter frame 501 symmetrically installed at the top and bottom ends inside the frame 3. The diverter frame 501 can guide the cooling gas. The diverter frames 501 are connected by a guide pipe 502. The cooling gas flows from top to bottom through the guide pipe 502. An air inlet 503 is installed at the top of the upper diverter frame 501. The cooling gas enters the diverter frame 501 through the air inlet 503. An air outlet 504 is fixed at the bottom of the lower diverter frame 501. The cooled gas is discharged through the air outlet 504 after use.

[0022] like Figure 2 As shown, a dust removal mechanism 7 is fixed inside the body 1. The dust removal mechanism 7 includes a mounting plate 701 fixed inside the body 1. Multiple sets of filter bags 702 are installed at equal intervals on the mounting plate 701 to facilitate fixing the filter bags 702 on the mounting plate 701 and purifying the black smoke through the filter bags 702.

[0023] like Figures 1-2 As shown, a back-blowing mechanism 8 is provided on one side of the top of the machine body 1. The back-blowing mechanism 8 includes an air tank 801, an electromagnetic pulse valve 802, an air guide pipe 803, and a nozzle 804, which facilitates the cleaning of the filter bag 702 through the back-blowing mechanism 8.

[0024] like Figures 1-2 As shown, the gas reservoir 801 is fixed on the outside of the machine body 1, and the electromagnetic pulse valve 802 is connected to the gas reservoir 801 pipeline, which can control the gas flow.

[0025] like Figures 1-2 As shown, the air guide pipe 803 is connected to the solenoid pulse valve 802 with a clamp, and the air guide pipe 803 extends into the machine body 1 to facilitate the delivery of backflush gas through the air guide pipe 803.

[0026] like Figures 1-2 As shown, the nozzle 804 is threadedly connected to the air guide pipe 803, and the number of nozzles 804 and the filter bags 702 are the same and their positions correspond, so that the backflush gas guided by the air guide pipe 803 can be sprayed onto the filter bags 702 through the nozzle 804, thereby backflush cleaning the filter bags 702.

[0027] like Figures 1-2 As shown, an exhaust pipe 6 is installed on the upper side of one side of the body 1, and a drain port 9 is opened at the bottom of the body 1, which allows the purified gas to be discharged through the exhaust pipe 6, while the impurities separated from the filter bag 702 are discharged from the body 1 through the drain port 9.

[0028] The working principle of this device is as follows: In actual use, black smoke enters the frame 3 through the inlet pipe 4. After entering the frame 3, the air inlet 503 in the cooling mechanism 5 is connected to the external air supply mechanism. Cooling gas enters the distributor 501 through the air inlet 503 and is evenly distributed to each guide pipe 502. The black smoke comes into contact with the guide pipes 502 during its flow, effectively cooling it. The used cooling gas is discharged through the outlet 504. Cooling the black smoke prevents excessive oily substances from adhering to the surface of the filter bag 702 due to high temperatures. This reduces the need for dust removal, prevents increased wear on the filter bag 702, and extends its service life. The cooled black smoke flows upward within the machine body 1. During this flow, impurities in the black smoke are filtered through the filter bag 702. The filtered gas then passes through the filter bag 702 and is discharged from the exhaust pipe 6 above the mounting plate 701. During use, the gas in the air tank 801 is guided through the air guide pipe 803 and sprayed onto the filter bag 702 through the nozzle 804, thereby backflushing and cleaning the filter bag 702. The impurities separated from the filter bag 702 are discharged from the machine body 1 through the drain port 9.

[0029] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
