Detailed Description
The principles and features of the present invention will be described with reference to the drawings, which are provided for illustration purposes only and are not intended to limit the scope of the present invention.
As shown in fig. 1, embodiment 1 of a water circulation system of a water ring vacuum pump 1 has the following structure:
the water ring vacuum pump 1 of the system is provided with an air inlet, an air outlet, a water inlet and a water outlet, and a circulating pipeline 4 is connected between the water inlet and the water outlet.
The air inlet is connected with an active carbon adsorption device 2 which is arranged in parallel, and the active carbon adsorption device 2 comprises a shell and active carbon filled in the shell. The shell has the intermediate layer that is used for letting in the cooling water, sets up like this, can strengthen the adsorption effect of active carbon to let in water ring vacuum pump 1 after making gaseous cooling, cool down its life inside water ring vacuum pump 1.
A heat exchanger 6, a buffer tank 7 and a water pump 8 are sequentially arranged in the circulating pipeline 4 in a serial connection mode from the water outlet to the water inlet, and a backflow pipeline 9 is connected between the water outlet end of the water pump 8 and the buffer tank 7; the gas-liquid separator 12 is connected to the gas outlet, and the liquid outlet of the gas-liquid separator 12 is connected to the buffer tank 7. The circulating pipeline 4 is internally provided with a filter 5, the filter 5 comprises filter cotton and a filter screen, and the filter 5 can filter various impurities entering the water to avoid damage or faults of the water ring vacuum pump 1.
The device 10 of softened water quality, preferred is parallelly connected on the pipeline between heat exchanger 6 and the delivery port, the device 10 of softened water quality includes cation exchange resin, and the resin granule is filled in the resin tank, and the center tube has been inserted at the resin tank center, and the upper end of center tube is equipped with the water-locator, and the lower extreme is equipped with down the water-locator, treats that softened water is by in going into the resin tank through last water-locator, treats that calcium, magnesium ion in the softened water exchange with the sodium ion on the resin granule, realizes the softening of quality of water, later softened water gets into the center tube through water-locator down to get into the outlet pipe through the center tube.
When the device is used in the embodiment, water to be softened is firstly introduced into the device 10 for softening water quality from the water inlet branch pipe 11, the generated softened water flows into the buffer tank 7 through the heat exchanger 6, and part of the water in the buffer tank 7 flows back and part of the water is pumped into the water ring vacuum pump 1 under the action of the water pump 8.
