The invention relates to a membrane separation and concentration
system for removing
heavy metals in waste
incineration fly ash, and aims to solve the technical problem of poor treatment efficiency caused by only pressure pushing when the
fly ash is treated by the current membrane separation, the membrane separation and concentration
system comprises a sulfydryl cleaning
tower, a gas inlet end of the sulfydryl cleaning
tower is communicated with a
fly ash discharge port, and a gas outlet end of the sulfydryl cleaning
tower is communicated with a gas outlet of the sulfydryl cleaning tower. By arranging the motor, the
flow divider and the limiting shell, when the motor runs, the motor can drive the driving disc to rotate through the driving shaft, so that the driving disc drives the limiting shell to rotate in the flow dividing outer shell, liquid with impurities can be reserved in the flow dividing inner
pipe, and pure liquid can be injected into the first treatment tank and the second treatment tank to be gasified and then discharged; according to the
system, when fly ash is treated, the condensed liquid treatment efficiency can be improved in a centrifugal acceleration mode, the flowing speed of condensed liquid in the
flow divider is increased while the filtering effect on the condensed liquid is guaranteed, and then the filtering effect of the system on fly ash liquid is improved.
