Abstract
The utility model provides a vacuum pump system, because the gas vent of the one end of blast pipe and vacuum pump is connected, the other end be the free end, and the free end is towards the storage water tank and apart from the uncovered predetermined distance of storage water tank, and consequently, during the steam that comes out from the gas vent of vacuum pump directly distributed the air, the circulating water was air -cooled naturally by the air at the in -process of inflow storage water tank, the storage water tank is uncovered, and the circulation fluid that is beneficial to in the storage water tank dispels the heat, consequently the utility model discloses a vacuum pump system simple structure practices thrift the water yield, can be in reduction circulation fluid temperature under the circumstances of the outer energy consumption of increase not.
Description
Technical field
This utility model belongs to vacuum pump technology field, is specifically related to a kind of vacuum pump system.
Background technology
When liquid concentration, often using and be concentrated in vacuo, can not only shorten concentration time, and the heat energy consumed is the most fewer, in generic container, vacuum is to use water ring vacuum pump to obtain.But, water ring vacuum pump is during using, and water ring vacuum pump is passed through to be needed to intake always, therefore, production process can use substantial amounts of water, and the chemical substance in steam can be absorbed due to water, therefore can produce substantial amounts of waste water, add the cost that waste water processes.
A kind of system saving vacuum pump water consumption of Patent No. CN104613021A, by increasing water tank and heat exchanger, will enter the water circulation use of water ring vacuum pump, thus reduces the usage amount of water, decreases the amount of waste water, reduce the cost that waste water processes.But, utilize heat exchanger by the water for cooling in water tank, heat exchanger is also required to consume substantial amounts of cooling water, and cools down water and be generally tap water or the cold water prepared through apparatus for supercooling, the most also can use substantial amounts of water or consume the substantial amounts of energy.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, reduces water consumption, and reduces the vacuum pump system of circulation fluid temperature in the case of not increasing additional energy.
This utility model provides a kind of vacuum pump system, including: air inlet pipe 10, vacuum pump 20, exhaustor 30, circulation fluid pipe 50 and uncovered storage tank 40, wherein, the air inlet 21 of vacuum pump 20 is connected with air inlet pipe 10, the air vent 22 of vacuum pump 20 is connected with one end of exhaustor 30, the other end of exhaustor 30 is free end 31, free end 31 towards and uncovered higher than storage tank 40, the outlet 41 of storage tank 40 passes through circulation fluid pipe 50 with the water inlet 23 of vacuum pump 20 and is connected.
Vacuum pump system of the present utility model can also do and further improve restriction: the radius of free end 31 is more than the radius of exhaustor 30, and the end face of free end 31 is provided with multiple hole 32.When recirculated water flows out in hole, the surface area of recirculated water and air contact can be increased, be more favorable for heat radiation.
Vacuum pump system of the present utility model can also do and further improve restriction: the bottom of storage tank 40 is provided with discharge outlet 42.When storage tank 40 needs to change circulation fluid, open the valve of discharge outlet 42.
Vacuum pump system involved by this utility model, because one end of exhaustor is connected with the air vent of vacuum pump, the other end is free end, free end is towards storage tank and the uncovered preset distance of distance storage tank, therefore, being directly emitted to air from the air vent of vacuum pump steam out, recirculated water is natural air cooled by air during flowing into storage tank；Storage tank is uncovered, the circulation fluid heat radiation in be beneficial to storage tank, and vacuum pump system simple in construction the most of the present utility model saves the water yield, it is possible to reduce circulation fluid temperature in the case of not increasing additional energy.
Accompanying drawing explanation
Fig. 1 is the easy structure schematic diagram of embodiment intermediate pump system of the present utility model；
Fig. 2 is the schematic diagram of the free end end face of exhaustor in embodiment of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reaching purpose and be easy to understand with effect, following example combine accompanying drawing and are specifically addressed vacuum pump system of the present utility model.
As it is shown in figure 1, vacuum pump system comprises: air inlet pipe 10, vacuum pump 20, exhaustor 30, uncovered storage tank 40 and circulation fluid pipe 50.One end of air inlet pipe 10 is connected with evaporator, and the air inlet 21 of vacuum pump 20 is connected with the other end of air inlet pipe 10, and the air vent 22 of vacuum pump is connected with one end of exhaustor 30.As shown in Figure 2, the other end of exhaustor 30 is free end 31, the radius of free end 31 is more than the radius of exhaustor 30, the end face of free end 31 is provided with multiple hole 32, and multiple holes 32 are evenly distributed on the end face of free end 31, and hole 32 can be circular, oval, square etc., circulation fluid in exhaustor flows out from multiple holes 32, can increase the contact area of circulation fluid and air, is more favorable for circulation fluid heat radiation.Free end 31 towards and uncovered higher than storage tank 40.In the present embodiment, the top 0.5m of the free end end face distance storage tank 40 towards 31.The outlet 41 of storage tank 40 is connected by circulation fluid pipe 50 with the water inlet 23 of vacuum pump 20.The bottom of storage tank 40 arranges discharge outlet 42, when needing to change the circulation fluid in storage tank 40, opens the valve of discharge outlet 42.
Vacuum pump 40 discharge steam and circulation fluid from exhaustor 30 out time, steam is exhausted directly to air, and circulation fluid is air-cooled by air dropping to storage tank 40 when, and the top of storage tank 40 is uncovered, the circulation fluid heat radiation being then more favorable in storage tank 40, thus save substantial amounts of cooling water.Due to wind-cooling heat dissipating, circulation fluid temperature rises relatively slow, and therefore the circulation fluid in storage tank can utilize the longer time to change, thus decreases the treating capacity of waste water, has saved cost.
Above-mentioned embodiment is preferred case of the present utility model, is not intended to limit protection domain of the present utility model.
