The invention discloses a multilayer efficient sodium sulfide impurity eliminating device. The efficient sodium sulfide impurity eliminating device is characterized in that a to-be-filtered sodium sulfide solution is contained in a material tank, a circulation motor drives a water pump to rotate at high speed, the water pump is connected with the interior of the material tank through draining pipe, the to-be-filtered sodium sulfide solution enters a liquid collecting tank through a liquid conveying pipe, the sodium sulfide solution diffuses in three directions and respectively passes a primary rear-side slag stopper, a secondary front-side slag stopper, a secondary rear-side slag stopper and a primary front-side slag stopper to complete the multistage filtering process, the filtered sodium sulfide solution is returned to the material tank through a liquid discharge pipe, and if necessary, the circulation motor and the water pump pumps the sodium sulfide solution into the liquid collecting tank again to start the filtering operation of next circulation. The multilayer efficient sodium sulfide impurity eliminating device has the advantages that the device can fast eliminate the impurities in the sodium sulfide solution, constant circulation can be performed to increase filtering effect, and the device is high in work efficiency and capable of reducing the labor intensity of operators.
