[0001] The utility model relates to the technical field of dust removal bags, in particular to an environmentally friendly bag dust removal device. Background technology:

[0002] In the processing and production process of chemical and industrial enterprises, a large amount of waste gas will be generated. The waste gas cannot be discharged directly, and the dust-containing gas needs to be filtered. Bag dust collector is an important link. When the dust-containing waste gas enters the dust bag, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material of the dust bag, the dust is retained and hung on the outer wall of the bag dust collector, so that the gas is purified. The existing bag dust collector is replaced after reaching saturation, and has no cleaning function, which leads to frequent replacement of bag dust collectors, increases equipment costs, and is not conducive to economic development. Utility model content:

[0012] Figure 3 It is a top view of the whole formed by the connecting pipe, the annular pipe and the flow guide pipe of the utility model. Specific implementation method:

[0013] Referring to the figures, the utility model specifically adopts the following implementation mode: comprising a device box 16, a device box 16 having an inlet pipe 2 on one side, a guide wall 8 in the device box 16, the guide wall 8 dividing the device box 16 into two chambers, namely a guide chamber 9 and a dust removal chamber 17, the dust removal chamber 17 is connected with the guide chamber 9, the guide chamber 9 is connected with the inlet pipe 2, the dust removal chamber 17 is vertically provided with a dust bag 11, the top of the dust bag 11 passes through the device box 16 and is connected with the purification chamber 7, the purification chamber 7 is arranged at the top of the device box 16, and the purification chamber 7 is arranged at the top of the device box 16. An outlet pipe 20 is provided on one side of the chemical chamber 7; the dust bag 11 is covered with an annular tube 14, and a brush 15 is provided on the inner wall of the annular tube 14. The brush head of the brush 15 contacts the outer wall of the dust bag 11. The two ends of the annular tube 4 are connected to the corresponding lifting mechanism through the connecting tube 13 respectively. The annular tube 4 is in communication with the connecting tube 13. One of the connecting tubes 13 is connected to the water tank 3 through an elastic hose 4. The elastic hose 4 passes through the guide wall 8. A sealing rubber ring is provided at the connection between the elastic hose 4 and the guide wall 8; the water tank 3 is placed in the guide cavity 9. Two dust bags 11 are provided in the dust removal cavity 17. The two dust bags 11 are arranged in parallel. The two dust bags 11 are covered with annular tubes 14 outside. The two annular tubes 14 are connected by the guide tube 12. The other side walls of the two annular tubes 14 are connected to the corresponding lifting mechanism through the connecting tube 13 respectively; the connecting tube 13, the annular tube 14 and the guide tube 12 are all in communication with each other. The lifting mechanism includes a motor 5, a driving wheel 6, a driven wheel 10 and a drive chain 1. The driving wheel 6 and the driven wheel 10 are arranged at the upper and lower parts of the dust removal chamber 17. The driving wheel 6 and the driven wheel 10 are connected by a drive chain 1, and the drive chain 1 is fixedly connected to the connecting pipe 13; the driving wheel 6 is connected to the motor 5 through a drive shaft. A lifting mechanism is provided on each side of the two dust removal bags 11. The drive chains 1 of the two lifting mechanisms support the whole formed by the connecting pipe 13, the annular pipe 14 and the guide pipe 12. The motors 5 of the two lifting mechanisms are driven synchronously, and the whole formed by the connecting pipe 13, the annular pipe 14 and the guide pipe 12 rises or falls through the lifting mechanism. The guide chamber 9 is connected to the bottom of the dust removal chamber 17. A collecting hopper 18 is provided below the dust removal chamber 17, and a sewage valve 19 is provided at the bottom of the collecting hopper 18.

[0014] When the environmentally friendly bag dust removal device is in use, the dust-containing exhaust gas enters the guide chamber 9 of the device box 16 through the inlet pipe 2, and enters the dust removal chamber 17 along the guide direction of the guide chamber 9. The larger and heavier dust particles in the dust-containing exhaust gas fall directly into the collecting hopper 18, and the fine dust passes through the dust removal bag 11 with the exhaust gas. When passing through the dust removal bag 11, the fine dust adheres to the dust removal bag 11, and the remaining exhaust gas enters the purification chamber 7 through the dust removal bag 11. The purification chamber 7 purifies the exhaust gas. The purification chamber 7 can be an activated carbon adsorption chamber or an ozone adsorption chamber, etc., as long as it can purify the exhaust gas. The gas passing through the purification chamber 7 is discharged through the outlet pipe 20.

[0015] After the dust bag 11 has been working for a period of time, the motors 5 of the two lifting mechanisms are started, and the two motors 5 are driven synchronously, that is, they rotate clockwise or counterclockwise at the same time. After the two motors 5 are turned on, they drive the driving wheels 6 connected thereto to rotate. Since the driving wheel 6 is connected to the driven wheel 10 through the driving chain 1, the driven wheel 10 rotates accordingly, thereby forming a moving mechanism. The driving chain 1 drives the connecting pipe 13, the annular pipe 14 and the guide pipe 13 to move together through the connecting pipe 13, rise or fall. When the connecting pipe 13, the annular pipe 14 and the guide pipe 13 rise or fall together, the brush 15 on the inner wall of the annular pipe 14 contacts the outer wall of the dust bag 11, and the brush 15 brushes off the dust attached to the dust bag 11 and drops it into the collecting hopper 18.

[0016] When the brush 15 brushes off the dust, in order to avoid the dust in the device box 16 from flying and causing pollution, the water tank 3 is started, and the water tank 3 injects water into one of the connecting pipes 13 through the elastic hose 4, and the water will flow into the annular pipe 14 and the guide pipe 12, and the two annular pipes 14 will be filled with water. The water filled in the annular pipes 14 will penetrate into the brush 15, and the brush 15 will be stuck with water. The water on the brush 15 will also come into contact with the dust, so that the dust will fall with the water, which will not be lifted up and will accelerate the falling speed.

[0017] The dust brushed off and the waste water seeping out through the brush 15 all fall into the collecting hopper 18, and the sewage valve 19 is opened to discharge the impurities in the collecting hopper 18 in a unified manner, thereby avoiding environmental pollution and achieving the purpose of environmental protection.

[0018] The motor 5, the water tank 3 and the drain valve 19 are all connected to an external controller via wires, and the operation of corresponding equipment is controlled by the external controller.

[0019] The driven wheels 10 used are connected to the inner wall of the dust removal chamber 17 through supporting shafts.

[0020] The adopted purification chamber 7 is communicated with the dust removal chamber 17 only through the dust removal bag 11 .

[0021] The guide wall 8 is used to separate the two chambers to prevent the waste from directly entering with too much impact force, which may damage the dust bag 11. The waste is allowed to move in the guide 9 for a while and enter the dust removal chamber 17 through the bottom, so that the exhaust gas moves from bottom to top and fully contacts the dust bag 11, thus completing the dust removal work efficiently.

[0022] To sum up, the environmentally friendly bag dust removal device has a simple structure and low manufacturing cost. It uses a lifting mechanism to drive the brush, which moves up and down on the outer wall of the dust bag, and brushes off the dust attached to the dust bag and drops it into the collecting hopper, thereby achieving the purpose of automatic cleaning of the dust bag and reducing the replacement frequency of the dust bag, thereby reducing the use cost of the equipment. A water tank is used to boil water for the brush to avoid pollution caused by flying dust. At the same time, the dust falls into the collecting hopper and is discharged and treated in a unified manner, avoiding environmental pollution and achieving the purpose of environmental protection.
