Beneficial effect of the present invention:
Gas to be clean enters purifier from tangential gas access, and rotation is risen in device.Absorption liquid enters from the liquid inlet, top.Liquid takes place broken under the turbulent shear effect of eddy flow field, makes gas-liquid fully contact.Like this, the impurity composition in the gas is absorbed and enters liquid phase and separate.
Absorption liquid drops in when moving downward in the eddy flow field, under centrifugal action, does the centrifugal sedimentation campaign to wall.This has just increased the gas-liquid relative velocity, has increased gas-liquid mass transfer Surface Renewal rate, thereby improves the mass transfer assimilation effect.
The moment of momentum of air-flow is kept in the effect of air deflector on the one hand, and on the other hand, it is middle that the absorption liquid that moves to wall is got back to, once more with the participation absorption process, to improve the utilization rate of absorption liquid.
Outer shroud on the air deflector plays the sealing function between air deflector periphery and wall, flows directly to liquid cylinder and no longer participates in absorption process by the slit between air deflector periphery and wall in order to avoid be thrown to the absorption liquid of wall, promptly is short-circuited.
The effect of mist eliminator is the absorption drop of collecting in the top gas.
This device is based on cyclone technique work.Gas speed is big more, and drop is broken more for a short time; On the other hand, gas speed is bigger, and the suffered centrifugal force of drop is also big more, is thrown on the wall and can form and carry secretly, therefore, can avoid liquid flooding fully.Because mist eliminator also is based on cyclone technique work, so gas is fast bigger, the suffered centrifugal force of drop is also healed big, and drop seizure separative efficiency is higher.Therefore, this device superficial linear velocity in a column operation greatly.In other words, compare with traditional absorption column of gas, under the condition of same processing requirements, same tower body size, the treating capacity of this device is much bigger, perhaps, under the condition of same processing requirements and same treating capacity, the equipment of this technology is much smaller, and promptly the unit volume treating capacity of this device is much bigger.In addition, this device adopts no nozzle for the absorption liquid technology, no blockage problem, and good reliability, and liquid-gas ratio is little, and required absorption liquid is less, thereby has reduced investment and operating cost.
This technical equipment also can be used for mass transfer, the diabatic process of other gas-liquid two-phases except can be used for the GAS ABSORPTION purification.
