Circulating water outlet；Wherein working solution pipeline one end has the working solution entrance for stretching out the water ring vacuum pump, and the other end has
Stretch out the working solution outlet of the water ring vacuum pump；Wherein the circulating water outlet and working solution entrance are set to the Water-ring vacuum
The side of pump, and circulation water inlet and working solution outlet are set to the other side of the water ring vacuum pump；And circulating water line, work
Make to be set in the middle part of liquid pipeline in the water ring vacuum pump, and by heat exchanger fin group to exchange heat；The wherein recirculated water
Entrance connect simultaneously softening water lines and underground water pipe with by softened water and underground water together as recirculated water；It is wherein described to change
Backing group includes intrinsic heat exchanger fin and newly-increased heat exchanger fin to improve heat transfer effect.
Wherein, the heat exchange mechanisms are plate heat exchanger, and the plate heat exchanger includes in horizontally disposed intrinsic heat exchange
Piece and the newly-increased heat exchanger fin being arranged in vertical direction, wherein the intrinsic heat exchanger fin and newly-increased heat exchanger fin all have inner cavity, and solid
There is the inner cavity mutual conduction of heat exchanger fin and newly-increased heat exchanger fin and is connected with circulating water line.
Wherein, the work liquid pipeline, which spirals, extends and is set between intrinsic heat exchanger fin and newly-increased heat exchanger fin so as to work
The recirculated water in the circulating water line in working solution and intrinsic heat exchanger fin and newly-increased heat exchanger fin in liquid pipeline carries out heat exchange.
Wherein, the underground water pipe connects underground water well by water pump underground water is transported to circulating water line.
The technical solution of the utility model has the advantage that
The water ring vacuum pump that above scheme proposes a kind of Power Plant goes out Force system, compares more existing water ring vacuum pump
Additional increase heat exchanger fin is increased, and increases underground water as recirculated water.Since underground water temperature is always at 20 DEG C or so, because
This uses underground water the temperature of vacuum pump working solution can be made to reduce at 26 DEG C or so as recirculated water, and unit vacuum improves about
1KPa。
Detailed description of the invention
The description carried out by a preferred embodiment with reference to the accompanying drawing to the utility model, the skill of the utility model
Art scheme and its technical effect will become clearer, and more easily understand.Wherein:
Fig. 1 is the structural schematic diagram of the water ring vacuum pump of the utility model embodiment.
Specific embodiment
It is described below with reference to a preferred embodiment of the appended attached drawing to the utility model.
The water ring vacuum pump that the utility model embodiment proposes a kind of Power Plant goes out Force system, as shown in Figure 1, packet
Include: water ring vacuum pump, wherein the water ring vacuum pump includes circulating water line, work liquid pipeline, heat exchange mechanisms；The wherein circulation
Water lines one end has the circulation water inlet 1 for stretching out the water ring vacuum pump, and the other end has the circulation for stretching out the water ring vacuum pump
Water out 2；Wherein working solution pipeline one end has the working solution entrance 3 for stretching out the water ring vacuum pump, and the other end, which has, to be stretched
The working solution outlet 4 of the water ring vacuum pump out；Wherein it is true to be set to the water ring for the circulating water outlet 2 and working solution entrance 3
The side of sky pump, and circulation water inlet 1 and working solution outlet 4 are set to the other sides of the water ring vacuum pump；And circulating water pipe
It is set in the water ring vacuum pump in the middle part of road, work liquid pipeline, and by heat exchanger fin group to exchange heat；It is wherein described to follow
