Description
Technical field
The utility model relates to vaccum-pumping equipment, is a kind of power plant special efficient vacuum pumping device.
Background technique
The normally used vaccum-pumping equipment of current thermal power generation corporations, it is mainly powerful Nash hytor, the deficiency vacuumized with this equipment is: along with ambient temperature rises, when circulating water temperature rises, the ability vacuumized is descended, if water temperature is from 15 ℃ rise to 35 ℃, the ability vacuumized descends more than 50%, this deficiency is embodied in summer especially, summer temp maintains 35 ℃ of left and right substantially, in whole summer, the vacuum capability of Nash hytor maintains lower level always, but, the power consumption of vacuum pump is constant, cause vaccum-pumping equipment efficiency very low.Ability when electricity power enterprise vacuumizes vapour condenser and the pipe-line system that is connected when summer declines to a great extent, and the power consumption of station service is increased relatively.
The model utility content
The purpose of this utility model is to provide a kind of power plant special efficient vacuum pumping device, it adopts the parts such as dry vacuum pump and liquid jetting device to form a kind of new vacuum pumping device, in vacuum capability on constant basis, power consumption significantly reduces, vacuum capability is not subject to the impact of ambient temperature basically simultaneously, makes it solve the deficiency that prior art exists.
The utility model for achieving the above object, be achieved through the following technical solutions: power plant's special efficient vacuum pumping device, each parts all are arranged on same chassis, the dry vacuum pump intake grill is connected with air intake pipe, and the dry vacuum pump the other end is connected with wind pipe, and the wind pipe the other end is connected with the spraying cooling tank, spraying cooling tank top connects air outlet tube, the air outlet tube the other end is connected with check valve, and the check valve the other end is connected with liquid jetting device, and the water outlet of liquid jetting device is connected with drainage system.The water inlet of liquid jetting device is connected with water pipe, and the water pipe the other end is connected with exit of pump, and pump entrance is connected with water system.The spraying cooling tank is connected with spraying tube one end, the spraying tube the other end is connected with water inlet system, spraying cooling tank one end is connected with waste pipe one end, then the middle part that waste pipe extends upwardly to the spraying cooling tank along the short transverse of spraying cooling tank extends downward below the spraying cooling pot bottom, the waste pipe the other end is connected with the dry vacuum pump intake, and the waste pipe top arranges bleed valve.Waste pipe is connected by 15 ° of-35 ° of gradients with the entrance of dry vacuum pump.
The vacuum pumping device that the utility model adopts the parts such as dry vacuum pump and liquid jetting device to form, solved the deficiency that prior art exists, compared with prior art, in identical vacuum capability situation, efficiency significantly improves, reduce power consumption and reach 70-85%, and have advantages of that the operating mode of vacuumizing is not subject to the work Water Temperature, after ambient temperature rises, the work water temperature is with in situation about rising, the ability vacuumized is substantially without reducing phenomenon, the utility model all can reach corresponding effect while using in summer and autumn in spring, for enterprise has reduced station service, has saved power consumption.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The contrast accompanying drawing is described further the utility model.
Power plant described in the utility model special efficient vacuum pumping device, each parts all are arranged on same chassis, dry vacuum pump 2 intake grills are connected with air intake pipe 1, dry vacuum pump 2 the other ends are connected with wind pipe 4, wind pipe 4 the other ends are connected with spraying cooling tank 3, and spraying cooling tank 3 tops connect air outlet tube 6, and air outlet tube 6 the other ends are connected with check valve 17, check valve 17 the other ends are connected with liquid jetting device 14, and the water outlet of liquid jetting device 14 is connected with drainage system.
Further program of the utility model is: the water inlet of liquid jetting device 14 is connected with water pipe 8, and water pipe 8 the other ends are connected with water pump 9 outlets, and water pump 9 entrances are connected with water system, and this structure is easy to connect, long service life.
The preferred scheme of the utility model is: spraying cooling tank 3 is connected with spraying tube 5 one ends, spraying tube 5 the other ends are connected with water inlet system, spraying cooling tank 3 one ends are connected with waste pipe 12 1 ends, then the middle part that waste pipe 12 extends upwardly to spraying cooling tank 3 along the short transverse of spraying cooling tank 3 extends downward below spraying cooling tank 3 bottoms, make waste pipe 12 be inverted U, waste pipe 12 the other ends are connected with dry vacuum pump 2 entrances, and waste pipe 12 tops arrange bleed valve.This structure can keep the pressure of the pressure of spraying cooling tank 3 and dry vacuum pump 2 entrances to keep constant differential pressure, makes whole system keep failure-free operation, thereby further keeps the advantage of low energy consumption.
Water in system directly can be entered to liquid jetting device 14 by water pump 9 in the utility model said structure, and sprayed by the outer pipe of liquid jetting device 14, make the air that comes from dry vacuum pump 2 be drawn into liquid jetting device 14 after water drenches, also by outlet conduit, spray in the lump, reached under the identical ability vacuumized the purpose that energy consumption significantly reduces.
