Description

TECHNICAL FIELD

[0001] The utility model relates to the field of gas purification, especially relates to a power wave scrubbing tower. BACKGROUND

[0002] In the recycling process of lithium battery pack, harmful tail gas and dust produced by crushing will be produced due to chemical reaction, at this time, the tail gas and air mixed with dust need to be washed by the power wave scrubbing tower, the principle is that the gas enters from the top of the power wave inverse spray pipe, flows from top to bottom, collides and contacts with the washing liquid sprayed from the nozzle from bottom to top, generates foam to carry out rapid and continuous gas-liquid exchange, and the dust and metal impurities in the gas enter the liquid phase and fall into the lower liquid storage tank.

[0003] However, the gas in the traditional power wave scrubbing tower enters at a high speed, and the contact with the washing liquid is not sufficient, which can easily cause the gas-liquid exchange to be not repeated, resulting in a significant reduction in washing efficiency and affecting production efficiency. The mixed washing liquid is reused for washing gas by the circulating pump, but when the liquid phase after mixing falls into the lower liquid storage tank and collides with the liquid surface, the washing liquid in the liquid storage tank is difficult to separate from the impurities, and directly entering the circulating pump can cause pipeline blockage or reduce the service life of the circulating pump.

When the gas enters the tower body 1, the contact reaction time between the gas and the washing liquid is extended when it passes through the flow guide component. The washing liquid that has completed the contact reaction falls onto the buffer component, and the degree of collision between the falling washing liquid and the liquid surface is reduced by the buffer component.

The outlet pipes 24 are located on the air inlet cylinder 12 and extend into the air inlet cylinder 12. One end of the connecting pipe 23 is connected to the output end of the circulation pump 21, and the other end is connected to the outlet pipes 24.
