Description

Technical Field

[0001] The utility model relates to the technical field of absorption devices, in particular to a novel coal gas cleaning tower. Background Art

[0002] Traditional gas scrubbers mainly rely on spray systems and packing layers to remove pollutants in gas, such as sulfides, nitrogen oxides and particulate matter.

[0003] Although the existing gas cleaning tower can purify the gas to a certain extent, the dust filtering effect at the air inlet is not ideal. Dust is a common pollutant in gas that is not easily dissolved by water. If it is not pre-treated, it will seriously affect the effect of subsequent spray washing, and may even clog the spray device and packing layer, reducing the working efficiency and service life of the entire cleaning tower. Therefore, we propose a new type of gas cleaning tower. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a new type of gas cleaning tower, which can solve the problem that dust is a common pollutant in coal gas that is not easily dissolved by water. If no pretreatment is performed, it will seriously affect the effect of subsequent spray washing and may even clog the spray device and the packing layer, thereby reducing the working efficiency and service life of the entire cleaning tower.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a new type of gas cleaning tower, comprising:

[0006] A cleaning tower, to which a dust filter box is connected via a flange;

[0007] A dust filtering structure, the dust filtering structure is located on the dust filtering box;

[0008] The dust filtering structure includes a driving motor, a threaded rod, a limiting sliding rod, a dust filter plate and a cleaning brush. The driving motor is fixedly connected to the top of the dust filter box, the dust filter plate is installed inside the dust filter box, the output end of the driving motor rotates through the top of the dust filter box and is fixedly connected to the threaded rod, the threaded rod is rotatably connected to the inside of the dust filter box, the limiting sliding rod is fixedly connected to the inside of the dust filter box, the cleaning brush is threadedly sleeved on the outer surface of the threaded rod, and the end of the cleaning brush away from the threaded rod is slidably connected to the limiting sliding rod.

[0009] Preferably, the dust filter box is fixedly connected to a gas inlet pipe on one side away from the cleaning tower, the interior of the dust filter box is slidably connected to a dust collecting box, and the inner bottom wall of the dust filter box is provided with a dust collecting trough connected to the interior of the dust collecting box.

[0010] Preferably, two packings are arranged inside the cleaning tower, and a plurality of maintenance windows for easy inspection and maintenance are provided on the outer surface of the cleaning tower.
