Help device.
Relative to prior art, the beneficial effect that the present invention is obtained is：
The retracting device that the present invention is adopted, recirculated water storage device and cooler are provided separately, only the water to circulation
Carry out cooling treatment, greasy dirt do not taken out of to water ring vacuum pump etc. is cooled down, the utilization of resources it is with strong points, improve resource
Utilization rate.
Recirculated water storage device is connected by the circulating water pipework positioned at its side middle and lower part with cooler, and can avoid will be upper
The greasy dirt or solid impurity taken out of in one cycle liquid is brought in circulation next time, can effectively improve following for circulating liquid
Ring number of times, substantially increases the utilization rate of recirculated water, can save great lot of water resources, makes production more environmentally-friendly.
Present invention employs gas-liquid and coagulate retracting device again, i.e., again solidifying reducing serves cooling effect by gas-liquid, obtains again
The cycling use of water of more meetings was obtained, the recycling rate of waterused to water was improve.
The present invention had installed condenser additional before water ring vacuum pump, the DMSO in gas was recycled, significantly
The residual volume of DMSO is reduced, the corrosivity of recirculated water is reduced.
