Description

Technical Field

[0001] This utility model relates to the field of filter tower technology, and in particular to a high-efficiency waste gas filter tower. Background Technology

[0002] When factories and other facilities discharge waste gas, the waste gas needs to be purified and qualified before it can be discharged. The commonly used waste gas filtration and treatment equipment is the spray tower.

[0003] Traditional spray towers mainly consist of multiple spray structures arranged along the height direction inside. For example, patent number CN115253644A, entitled "A Waste Gas Spray Tower Filtration Device for Waste Gas Treatment," describes a filter tower with a dewatering cyclone plate, spray pipes, and a stirring mechanism inside. While this can remove harmful substances from the waste gas, the dewatering cyclone plate and stirring mechanism are not only complex in structure, expensive, and energy-intensive, but also hinder waste gas emissions and reduce the purification efficiency.

[0004] Therefore, how to design a high-efficiency exhaust gas filter tower that is simple in structure, low in cost, and has high purification efficiency is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This invention provides a high-efficiency exhaust gas filter tower, which solves the technical problems of existing exhaust gas filter towers having complex structures and low purification efficiency.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a high-efficiency exhaust gas filtration tower, comprising: a tower body, a cylindrical body, a water collection tank, and multiple rotating spray pipes.

[0007] The lower side wall of the tower body is provided with an exhaust gas inlet and a water collection hole, and its top is provided with a clean gas outlet. The cylindrical wall is arranged along the height direction of the tower body and its bottom end is fixed to the bottom end of the tower body. The cylindrical body is provided with multiple sets of water outlet holes spaced apart along its axial direction, and its top end is a closed end. The multiple sets of water outlet holes include multiple water outlet holes spaced apart along the circumference of the cylindrical body. The water collection tank is fixed to the outer wall of the tower body, and its water inlet is connected to the water collection hole. A filter is fixed at the water inlet of the water collection tank, and a water pump is fixed inside it. The water pump passes through the connecting pipe. The water collection tank is inserted into the tower body and communicates with the cylinder body; multiple rotating nozzles are arranged perpendicular to the cylinder body, and the upper and lower pipe walls in the middle are provided with opposite through holes. The lower pipe wall of the multiple rotating nozzles is provided with multiple water spray holes distributed at intervals along its axial direction. The two pipe walls near its two ends of the multiple rotating nozzles are provided with driving holes, so that after two driving holes spray water in opposite directions, the corresponding rotating nozzle is driven to rotate; the cylinder body rotates through the through holes of the multiple rotating nozzles, and the water outlet is connected to the through hole of the corresponding rotating nozzle.

[0008] The beneficial effects of this utility model are as follows: The exhaust gas filter tower structure is designed in a completely new way. First, the water collection tank is connected to the tower body to repeatedly recover the water used for filtration in the tower body, thereby reducing the water consumption of the filter tower. Then, a water pump is used to pass the water in the water collection tank into the cylinder and the rotating nozzle. Since there are drive holes on the opposite sides of the rotating nozzle and multiple spray holes on the lower pipe wall, the rotating nozzle can be driven to rotate by the water passing into it. This causes the water flow from the multiple spray holes to spiral down in the tower body, increasing the contact area between the water flow and the exhaust gas and improving the purification efficiency of the exhaust gas.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the outer wall of the cylinder corresponding to the plurality of rotating nozzles is provided with annular grooves; the pipe walls of the plurality of rotating nozzles corresponding to their through holes extend into the annular grooves.

[0011] The further beneficial effect of adopting the above is that by extending the rotating nozzle into the corresponding cylinder annular groove, the rotating nozzle can be prevented from slipping off.

[0012] Furthermore, it also includes multiple support frames, all of which are located inside the tower body and are spaced apart along the height direction of the tower body. One end of each of the multiple support frames is fixed to the inner wall of the tower body and the other end is fixed to the cylinder.

[0013] The further beneficial effect of adopting the above is that by fixing one end of multiple support rods to the inner wall of the tower body and the other end to the cylinder body, the stability of the cylinder body can be improved.

[0014] Furthermore, it also includes multiple ring pipes, which are fixed at intervals within the tower body along the height direction of the tower body. Each ring pipe is provided with multiple spray holes distributed at intervals along its circumference. The water pump passes through the water collection tank and into the tower body via a connecting pipe and is connected to the multiple ring pipes.

[0015] The further beneficial effect of adopting the above method is that by using multiple ring pipes to spray into the inside of the tower, the entire internal space of the tower can be filled, thus preventing the direct discharge of waste gas.

[0016] Furthermore, it also includes a switch door, and the top surface of the water collection tank is provided with a switch hole; the switch door is hinged at the switch hole. Attached Figure Description
