Description

Technical Field

[0001] The utility model belongs to the field of wet dust removal, in particular to a countercurrent wet dust removal tower. Background Art

[0002] The wet dust removal produced by the company combines the water bath and spraying into one. First, the suction of the high-pressure centrifugal fan is used to press the dust-containing gas into a water tank filled with water at a certain height. The water bath will adsorb part of the dust in the water. After uniform distribution and diversion, the gas flows from bottom to top, and the high-pressure nozzle sprays water mist from top to bottom to capture the remaining dust particles. Its filtration efficiency can reach more than 85%. In the wet dust removal tower equipped with a packing layer, the liquid flows down from the top of the tower along the surface of the packing and forms a thin film on the surface of the packing. When the dust-containing gas passes through the packing layer, the dust particles hit the surface of the wet packing and are captured and removed. It can remove dust particles with a particle size of more than 3μm, and the dust removal efficiency is about 90%, the airflow pressure loss is 1.5-5kpa, and it has a simple structure, is easy to manufacture, and is cheap.

[0003] Based on the above, the inventors found the following problem: the filtering effect of the dust removal tower on smoke depends on the distance the smoke moves in the packing layer. If the thickness of the packing layer is increased, the space required for installation of the device will increase, resulting in increased installation costs.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a countercurrent wet dust removal tower is provided to achieve a more practical purpose. Utility Model Content

[0028] Example:

[0029] As attached Figure 1 To Attachment Figure 6 As shown:

[0030] The utility model provides a countercurrent wet dust removal tower, comprising a tower body 1, wherein two groups of dust reduction devices are arranged inside the tower body 1, wherein the dust reduction device comprises a spray assembly and a filler assembly arranged below the spray assembly, wherein the filler assembly comprises a slot arranged on one side of the tower body 1, wherein a drawer 2 is installed inside the slot, and a baffle 3 is also installed on the side where the drawer 2 passes through the slot, wherein a pair of sliders 4 are respectively arranged on both sides of the drawer 2, and slide grooves 5 corresponding to the sliders 4 are opened on the inner walls on both sides of the tower body 1, wherein the slide grooves 5 are slidably connected with the sliders 4, and grooves 6 are also arranged between the pair of sliders 4 on both sides of the drawer 2, wherein a slot hole is arranged on the side of the groove 6 away from the baffle 3, and a card block 7 is also arranged in the groove 6, wherein a connecting rod 8 is installed through one end of the card block 7, wherein one end of the connecting rod 8 penetrates into the slot hole on the groove 6 and is connected to the slot hole, and the other end of the connecting rod 8 penetrates the drawer 2 and the baffle 3 and is rotatably connected with the drawer 2 and the baffle 3. A card slot 9 corresponding to the position of the card block 7 is opened on the inner walls of both sides of the tower body 1. The card slot 9 is adapted to the size of the card block 7 and can be connected by card engagement. Through the coordinated use of the drawer 2, the slide slot 5, the slider 4, the connecting rod 8, the card block 7 and the card slot 9, the card block 7 and the card slot 9 are engaged or separated by rotating the connecting rod 8, so that the fixation and loosening of the drawer 2 can be achieved. When the card block 7 and the card slot 9 are separated, the drawer 2 can be pulled out from the tower body 1, so that the internal filler 21 can be replaced. After that, the drawer 2 after the filler 21 is replaced is inserted into the tower body 1 and the connecting rod 8 is rotated to engage the card block 7 and the card slot 9, so that the fixation of the drawer 2 can be completed, thereby facilitating the replacement of the filler 21 and reducing the maintenance time of the dust removal tower. A plurality of cylindrical grooves 10 are opened in the internal array of the drawer 2, and spiral blades 11 are fixedly provided inside the cylindrical grooves 10.

[0031] The spray assembly includes a water pipe 12, and a plurality of nozzles 13 are installed in an equidistant array at the bottom of the water pipe 12. Water mist is sprayed from the nozzles 13, thereby cooperating with the filler assembly to achieve the filtering effect on smoke and dust.

[0032] Among them, an air inlet 14 is provided on one side of the bottom of the tower body 1, a sewage outlet 15 is provided at the bottom of the air inlet 14 of the tower body 1, a defogger 16 is installed above the spray assembly at the top of the tower body 1, and an air outlet 17 is provided on the top of the defogger 16 of the tower body 1. Through the coordinated use of the air inlet 14, the sewage outlet 15 and the air outlet 17, it is achieved that after the smoke enters the tower body 1, it gradually moves to the top air inlet 14 through the bottom air inlet 14, and after being filtered by the spray assembly and the filler assembly, the filtered clean gas is discharged from the air outlet 17, and the filtered liquid is discharged from the drain port. By installing the defogger 16 on the top, the moisture content of the gas can be reduced after the gas is filtered by the defogger 16, thereby saving the water required for filtration and reducing the filtration cost.

[0033] Among them, a fluororubber pad 18 is provided on the surface of the baffle 3 close to the tower body 1. By adding the fluororubber pad 18, the sealing performance between the baffle 3 and the surface of the tower body 1 can be improved to prevent smoke and dust from escaping from the joints and causing environmental pollution. The fluororubber material has good heat resistance and corrosion resistance, thereby extending the service life of the fluororubber pad 18 and reducing the risk of air leakage due to rubber aging causing the contact surface between the baffle 3 and the tower body 1 to leak.

[0034] Among them, one end of the connecting rod 8 located in the slot hole of the groove 6 is provided with a thread, and the connecting rod 8 is threadedly connected to the slot hole opened on the groove 6. By providing a thread at one end of the connecting rod 8, when the connecting rod 8 is rotated to engage the clamping block 7 and the clamping slot 9, the connecting rod 8 will move to the side of the baffle 3, and the clamping block 7 is driven to move by the connecting rod 8, so that the clamping block 7 pulls the baffle 3 connected to the drawer 2 to make it fit tightly with the outer surface of the tower body 1, thereby making the air tightness of the connection between the drawer 2 and the tower body 1 better, and further preventing smoke and dust from leaking from the connection between the drawer 2 and the tower body 1 to pollute the surrounding environment.

[0035] Among them, a connecting block 19 is fixedly installed on the end of one side of the connecting rod 8 extending out of the baffle 3, and a handle 20 is installed on the surface of the baffle 3 away from the tower body 1. Through the coordinated use of the connecting block 19 and the handle 20, it is convenient for the operator to twist the connecting rod 8 to separate the block 7 and the slot 9 before pulling out the drawer 2, thereby changing the drawer 2 from a fixed state to a movable state. In addition, by installing the handle 20, it is convenient for the operator to pull out the drawer 2, thereby improving the work efficiency of replacing the filler 21.

[0036] Among them, multiple cylindrical grooves 10 are filled with fillers 21, and the top and bottom of the cylindrical grooves 10 are installed with blocking nets 22. Through the coordinated use of the spiral blades 11, the cylindrical grooves 10, and the blocking nets 22, when the smoke passes through the filler 21, the movement distance of the smoke passing through the filler 21 is extended, and the adhesion rate of the smoke to the surface film of the filler 21 is increased, thereby improving the dust removal rate of the device. The aperture of the blocking net 22 is smaller than the size of the filler 21. By limiting the mesh size, the filler 21 can be prevented from falling from the mesh, resulting in a reduction in the smoke filtering effect of the filler 21, thereby reducing the dust removal rate of the device.

[0037] The specific usage and function of this embodiment are as follows:

[0038] Before the installation and use of the utility model, the staff needs to check the internal components or structures of the device. After the inspection is correct, it can be used normally. First, the connecting blocks 19 on the connecting rods 8 on both sides are twisted respectively to separate the slots 9 and the blocks 7, and then the drawer 2 is pulled out from the tower body 1 through the handle 20, and then the blocking nets 22 at the top and bottom of the cylindrical slots 10 are removed, and then the stuffing 21 between the cylindrical slots 10 and the spiral blades 11 is taken out, and then new stuffing 21 is filled in and covered with the blocking nets 22, and then the drawer 2 is inserted into the tower body 1 again, and the connecting blocks 19 on both sides are twisted respectively to make the connecting rods 8 drive the blocks 7 and the slots 9 to re-engage, and after the fixation is completed, the stuffing 21 of the next stuffing assembly can be replaced. The above steps can complete the rapid replacement of the stuffing 21 in the wet dust removal tower, reduce the time required for maintaining the dust removal tower, and extend the movement distance of the smoke in the stuffing assembly, thereby increasing the dust removal effect of the device.
