Description
Technical field
The utility model is related to high temperature circulation Recovery of the hot water equipment more particularly to a kind of high temperature circulation Recovery of the hot water with pressure
System.
Background technology
A large amount of low-temperature water heating is had in chemical production technology for circulating cooling high-temperature material, hot water temperature may be up to
130 DEG C, in order to realize cooling, generally use recirculated cooling water is cooled down, while on-site has a large amount of pipe network mesohigh
Steam after pressure and temperature reducing by using.Conventional occupation mode has had resulted in the very big wasting of resources at present.
Utility model content
In view of the above-mentioned state of the art, the technical problem to be solved by the utility model is to provide it is a kind of it is energy saving,
Efficient high temperature circulation hot water recovery system with pressure.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of high temperature circulation hot water with pressure returns
Receipts system, pumps including flash tank and steam ejection, and the flash tank upper/lower terminal is respectively equipped with low pressure flash vapor outlet and cycle
Water recovery port, high temperature circulation hot water inlet is equipped in the flash tank side, and the jet pump includes low-pressure steam inlet, driving
Steam inlet and output steam port, the low pressure flash vapor outlet of the flash tank are entered by the low-pressure steam of pipeline connection jet pump
Mouthful, regulating valve is equipped at the driving steam inlet, pressure transmitter and temperature are equipped between output steam port and regulating valve
Transmitter is connected with drain valve in the high temperature circulation hot water inlet front end.
Further, check-valves is equipped at the low pressure flash vapor outlet.
Further, it is equipped with safety valve in the flash tank side.When equipment pressure rise is to predetermined value, safety valve is certainly
Dynamic open opens pressure release, prevents equipment pressure from continuing to increase, and when pressure reduction is to specified value, safety valve closes prevent from setting in time
Standby interior medium is lost in.
Compared with prior art, the utility model has the advantage of：The utility model is using warm by the high temperature circulation discarded
Water generates low-pressure steam by flash tank, and low-pressure steam is steamed with middle pressure steam by the mesolow that jet pump generation technique uses
Vapour.The pressure shown by the pressure transformer on low pressure steam pipeline and temperature transformer adjusts on high-tension side regulating valve and opens
Degree, more intelligently, safely.The utility model is designed reasonably is suitble to large-scale promotion.
Description of the drawings
Fig. 1 is the utility model a kind of structure and flow diagram of high temperature circulation hot water recovery system with pressure.
Specific embodiment
With reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear

All other embodiments obtained shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of high temperature circulation hot water recovery system with pressure, pumps including flash tank 10 and steam ejection
7,10 upper/lower terminal of flash tank is respectively equipped with low pressure flash vapor outlet 2 and circulating water reclamation mouth 11, in the flash tank 10
Side is equipped with high temperature circulation hot water inlet 1, and the jet pump 7 includes low-pressure steam inlet 4, driving steam inlet 5 and output and steams
Steam ports 8, the low pressure flash vapor outlet 2 of the flash tank 10 connect the low-pressure steam inlet 4 of jet pump 7, the sudden strain of a muscle by pipeline
The circulating water reclamation mouth 11 of steaming pot 10 connects the watering equipments such as boiler room by pipeline.It is equipped with and adjusts at the driving steam inlet 5
Valve 6 is saved, pressure transmitter and temperature transmitter 9 are equipped between output steam port 8 and regulating valve 6, in high temperature circulation heat
1 import front end of water is connected with drain valve.Check-valves 3 is equipped at the low pressure flash vapor outlet 2.It is set in 10 side of flash tank
There is safety valve.When equipment pressure rise is to predetermined value, safety valve automatically opens unlatching pressure release, prevents equipment pressure after of continuing rising
Height, when pressure reduction is to specified value, safety valve is closed in time prevents medium in equipment to be lost in.
Compared with prior art, the utility model has the advantage of：The utility model is using warm by the high temperature circulation discarded
Water generates low-pressure steam by flash tank, and low-pressure steam is steamed with middle pressure steam by the mesolow that jet pump generation technique uses
Vapour.The pressure shown by the pressure transformer on low pressure steam pipeline and temperature transformer adjusts on high-tension side regulating valve and opens
Degree, more intelligently, safely.The utility model is designed reasonably is suitble to large-scale promotion.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of skill in the art that its according to
So it can modify to the technical solution recorded in foregoing embodiments or which part technical characteristic is replaced on an equal basis
It changes；And these modifications or replacement, various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
Spirit and scope.
