Description
Technical field:
The invention belongs to Thermal Power Engineering Field, relate to a kind of injection heat exchange and supercharging device.
Background technology:
Water-water jet (water-water sprays the supercharging heater) operation principle is that pressure is P
0Working fluid (as the high-temperature water of introducing from outdoor hot water net) through jet pipe with very big speed w
1Ejection is because the effect of entrainmenting of this strand jet causes a pressure P than driven fluid (as the backwater of heating system) at the mixing chamber inlet place
hAlso low low-pressure area, its pressure are P
2, driven fluid is constantly with w
2Flow velocity suck mixing chamber.Working fluid collides mutually with the molecule of driven fluid and mixes in mixing chamber, makes two kinds of fluid velocities grade gradually, and simultaneous temperature also reaches unanimity, then with w
3Flow velocity enter diffuser pipe.The flow velocity of fluid-mixing is reduced to w gradually in diffuser pipe
g, pressure is increased to P gradually
gWater-water jet is flowed out in the back.Water-water jet is used for the high-temperature water heating system, desirable generation heat exchanger and water circulating pump, it has following characteristics:
(1) saves energy.The pressure that can make full use of working water with water-water jet can be saved the water pump power consumption.
(2) belong to hybrid heating, thermal efficiency height is near 100%.
(3) simple to operate, reliable.Maintenance load is little, reduces recondition expense.
(4) simple in structure, volume is little, and is in light weight, can save a large amount of metal materials, reduces manufacturing cost, and floor space is little, saves the heat exchange station construction area.
But existing water-water jet is used for heating system, has following problem:
The working condition of water-water jet is with to enter the working heat water pressure of water-water jet closely related, the working heat water pressure must be in certain scope could operate as normal, otherwise vibration, noise will occur even can not work.In hot-water heating system, for guaranteeing the heating requirement when temperature is the coldest, the water-water jet in the heat exchange station should design by the coldest, the whole heat supply network thermic load of temperature parameter the highest, when the working heat water pressure is minimum.In actual motion, when outside air temperature raises, should reduce thermic load, need turn down working heat water inlet valve throttle, reduce the flow of work hot water, the preceding working heat water pressure of jet pipe is reduced, working heat hydraulic pressure falls and flow all reduces, may cause water-water jet vibration, noise to occur, even can not work, be difficult to satisfy the heating requirement.
Summary of the invention:
The purpose of this invention is to provide a kind of adjustable water-water jet (can adjust water-water and spray the supercharging heater) by needle valve 1, working heat hydroecium 2, by injection hydroecium 3, working heat water spray pipe 4, by injection water spray pipe 5, mix diffuser pipe 6, sliding sleeve 7, sliding sleeve support 8, sealing ring 9, base plate 10, hydroecium support 11, sealing ring 12, needle valve supporting sleeve 13, needle valve sealing 14, handwheel 15 etc. and form.
With the adjustable needle valve 1 of needle valve supporting sleeve 13, needle valve sealing 14, handwheel 15 controls, adjust working heat water spray pipe 4 discharge area.
What the shape of 1 head of adjustable needle valve (itself and working heat water spray pipe 4 outlet mating parts) was parabolic type, pyramid type or parabolic type with during pyramid type combines is a kind of.
Mix with sliding sleeve 7 adjustment the suction inlet inwall of diffuser pipes 6 and working heat water spray pipe 4 outer wall by injection water spray pipe 5 discharge area.
For guaranteeing the heating requirement when outside air temperature is minimum, adjustable water-water jet is the highest according to minimum, the whole heat supply network thermic load of temperature, the working heat water pressure designs when minimum.When thermic load reduces, by adjusting working heat water spray pipe discharge area, reduce working heat discharge and do not reduce its pressure, but also can utilize, increase of the pressure drop of working heat current through the working heat water spray pipe because whole heat supply network thermic load reduces pressure elevated pressure energy; And by adjusting by injection water spray pipe discharge area, under not to the situation of backwater throttling, suitably turn the backwater amount down, mixing back heating coolant-temperature gage and flow are suitably reduced, and adjustable water-water jet still can be in substantially and moves under the designing optimal parameter, guarantee its operate as normal, therefore increased adjustable range, the heating requirement when satisfying different weather can be given full play to its advantage that has.
Description of drawings:
Accompanying drawing is a structure chart of the present utility model.
Below in conjunction with accompanying drawing, further specify content of the present invention.
For achieving the above object, adjustable water mixer (capable of regulating water-water sprays the supercharging heater) is designed to attached The structure of figure. Wherein working heat hydroecium 2, by injection hydroecium 3, working heat water spray pipe 4 with by the injection water spray pipe 5 are fixed on the hydroecium support 11; Mix diffuser pipe 6, sliding sleeve 7 and sliding sleeve sealing ring 9,10 and be fixed on sliding sleeve On the support; Hydroecium support and sliding sleeve support are drawn at working heat water pipe 4, quilt sprays water pipe 5, mix diffuser pipe 6 After being adjusted into one heart, be fixed on together on the base plate 10; Adjustable needle valve 1, handwheel 15 and needle valve sealing 14 are fixed in the working heat hydroecium by needle valve supporting sleeve 13.
