Heating.
Further, the end of nozzle is provided with straight length.Being provided with for straight length forms stabilization beneficial to injection water
Liquid stream, reduces the generation of vortex, it is ensured that vacuum effect.
Further, the jet pump is that lift is the centrifugal water pump of 30-70 meter water columns.The water of 30-70 meter water column lifts
Pump ensure that the vacuum effect produced by injector.
Further, difference in height >=12 meter of the gas feed of the tank deck of the condensation water collection tank and injector, and injection
Height of the height of the gas feed of device higher than the tank deck of condensation water collection tank.Difference in height is set to >=12 meters, is in order to anti-
Only condensed water is taken directly in injector.
Further, the outer wrap of the condensation water collection tank has heat-insulation layer.With reduce condensed water heat energy to external diffusion.
Further, the liquid outlet of the injector is connected in process water pond.Can so be used with circulation use technology
Water in pond, makes the temperature of the water in process water pond improve as far as possible.
The utility model is used as power source by the use of water by the negative pressure produced by injector, steam condensate (SC) is formed low pressure
, then be drawn into low-pressure steam in injector by steam, and is mixed with injection with water, heats injection water, injection water
The process water, or boiler feed water of heating can be needed, steam condensate (SC) is extracted as a result of the mode of evaporation
In heat energy, it is to avoid the impurity that directly steam condensate (SC) is brought as process water or boiler feed water, as steam is cold
The evaporation of lime set, is not only able to recovery section heat energy, moreover it is possible to recovery section steam condensate (SC), reduces the pressure of sewage disposal,
Also reduce the energy cost of enterprise., it is necessary to first by reclamation of condensate water to condensation water collection before utility model works
Tank, operationally, it is necessary to the switch valve that will be condensed on water inlet is closed, to ensure the negative pressure of condensation water collection tank.
Brief description of the drawings
Fig. 1 is a kind of structural representation of embodiment of the present utility model.
Specific embodiment
Embodiment 1：
Refering to Fig. 1, a kind of steam condensate (SC) reclamation set, it includes condensation water collection tank 10, jet pump 20, injector 30
With process water pond 40；The condensation water inlet 11, low pressure for collecting steam condensate (SC) is provided with condensation water collection tank 10
Steam (vapor) outlet 12 and the evacuation port 15 for being arranged on bottom, are provided with exhaust-valve 16 on evacuation port 15, on condensation water inlet 11
Switch valve 13 is installed；The injector 30 is venturi type injector, and injector is provided with liquid-inlet 31, gas feed 32
With liquid outlet 34；The import Joining Technology millpond 40 of jet pump 20, the outlet 22 of jet pump 20 connects the liquid of injector 30
Body import 31, the low-pressure steam outlet 12 of the connection condensation water collection of gas feed 32 tank 10 of injector 30.In condensation water collection
The outer wrap of tank has heat-insulation layer 14.The liquid outlet of injector is connected in process water pond.
In the present embodiment, injector 30 includes vacuum cylinder 36, is inserted from one end of vacuum cylinder along the axis 38 of vacuum cylinder 36
Enter the nozzle 35 of the inner chamber of vacuum cylinder, the other end of vacuum cylinder is connected with mixing chamber 33, and nozzle 35 is located at outside vacuum cylinder
End forms the liquid-inlet 31 of the injector, and the gas feed 32 of above-mentioned injector is formed with the side wall of vacuum cylinder, described
Mixing chamber 33 is tapered, and the stub end connection vacuum cylinder 36 of mixing chamber 33, the small head end of mixing chamber 33 forms above-mentioned injector
Liquid outlet, straight length 37 is provided with the end of nozzle.
In the present embodiment, it is the centrifugal water pump of 30-70 meter water columns that jet pump uses lift.The gas feed of injector
Highly higher than condensation water collection tank tank deck height, and the gas feed of tank deck and the injector of condensation water collection tank height
>=12 meters of difference.
, it is necessary to steam condensate (SC) is collected into condensation water collection tank first before the present embodiment work, and in process water
There is enough water in pond, then close the switch valve 13 on condensation water collection tank, open jet pump, jet pump is by process water
Water in pond is squeezed into injector, when water sprays from the nozzle of injector, with the gas in vacuum chamber from the liquid of injector
Body import is discharged, and is returned in process water pond, is recycled.
Because the gas in vacuum chamber tails off, negative pressure is produced, while making in the condensation water collection tank that is connected with vacuum chamber
Negative pressure is produced, when the pressure for vaporization corresponding to the pressure in condensation water collection tank is reduced to the temperature of condensed water, condensed water is received
Condensed water in collection tank comes to life, and produces low-pressure steam, and these low pressure can neatly be injected pumping and enter, and is sprayed with from nozzle
The water for going out is mixed, because low-pressure steam contains substantial amounts of heat energy, so that the partial heat energy in condensed water is through low-pressure steam quilt
It is transferred in the water in process water pond, while also partial condensation liquid is also into the water in process water pond.
Water circulation in process water pond is squeezed into injector, until can not again by the condensed water in condensation water collection tank
Untill vaporization.It is of course also possible to certain negative pressure value is set, as soon as after the negative pressure in condensation water collection tank reaches setting value,
Stop energy recovery, the remaining water in condensation water collection tank is discharged from evacuation port, regathering new steam condensate (SC) carries out heat
Can reclaim.
