Description

Technical Field

[0001] The utility model relates to the technical field of adsorption towers, in particular to an organic silicon tail gas treatment absorption and adsorption tower. Background Art

[0002] Silicone is widely used in electronics, information, energy and many other fields, making it an indispensable material for many industries. As the industry trend increases, the demand for silicone is also increasing, and the purity requirements are also getting higher and higher. However, the waste gas of silicone is toxic and flammable and explosive. It is difficult to handle such waste gas.

[0003] When treating organosilicon waste gas, the absorption method is generally used. The absorption method is divided into two types, one is spraying type, and the other is directly introduced into water. Both methods have their own disadvantages. The spraying absorption method is prone to uneven spraying, and the direct introduction into water has a relatively small contact area between the gas and water, which may limit the reaction opportunity between the pollutants and the absorbent. For this reason, we propose an organosilicon tail gas treatment absorption and adsorption tower. Utility Model Content

[0006] Preferably, the driving assembly includes a first gear, a second gear and a motor, the first gear is installed on the top end of the rotating rod, the first gear is meshed with the second gear, and the second gear is connected to the output end of the motor.

[0007] Preferably, a filter is sleeved on the outer portion of the lower end of the rotating rod and located between the two groups of stirring rods, and the filter is communicated with the inner cavity of the lower end of the rotating rod.

[0008] Preferably, the upper end of the rotating rod is located above the sprayer and is sealed and rotatably connected to an adsorption component, and the adsorption component is connected to the inner wall of the tower body.

[0009] Preferably, a third connecting pipe and a fourth connecting pipe are installed through one side of the tower body, and an exhaust port is opened through the top of the tower body.

[0010] Preferably, the bottom end of the tower body is installed in the inner cavity of a support member, and the support member is an L-shaped structural member.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The lower end of the tower body of the utility model is filled with absorbent, and the tail gas is directly introduced into the absorbent. The driving component can drive the rotating rod to rotate, and then drive the stirring rod to rotate, which can drive the absorbent to flow and accelerate the reaction efficiency between the absorbent and the tail gas. At the same time, the extraction pump is running to extract the absorbent from the second connecting pipe and pass it into the sprayer through the first connecting pipe for spraying. The rotation of the rotating rod can drive the sprayer to rotate, and the spraying is more uniform. Compared with the prior art, the two methods of absorption in water and spraying absorption are combined, which avoids the relatively small contact area between gas and water when passing into water, limits the reaction opportunity between pollutants and absorbent, and the problem of uneven spraying, and has higher absorption efficiency.

[0013] 2. The utility model utilizes the filter element to play a filtering role to prevent the sediment produced by the reaction from clogging the second connecting pipe. The tail gas after the reaction is adsorbed by the adsorbent and then discharged from the exhaust port. The third connecting pipe is used to pass the absorbent, and the fourth connecting pipe is directly passed into the absorbent, so that the tail gas can directly enter the absorbent. The support member is an L-shaped structural member, the horizontal member is used to support the tower body, and the longitudinal member is used to install the extraction pump and motor and other components.
