Abstract
A steam injection pump consists of conventional injection pumps connected in parallel and particularly comprises a first-stage injection pump, a second-stage injection pump and a third-stage injection pump. Steam pipes are respectively connected to the upper ends of the injection pumps, lower ends of the injection pumps are connected to lower ends of condensers, upper ends of the condensers are connected with a water inlet pipe, and discharge pipes are arranged right below the condensers and connected to the inside of a water tank. The steam injection pump has higher vacuum degree capable of meeting requirements of industrial use.
Description
Technical field
The present invention relates to vapor pump, belong to the chemical industry equipment field.
Background technique
Jet pump is that fluid is inhaled, sent to the static energy when utilizing fluid to flow with the principle that dynamic pressure can be changed each other, and it both can be used for the suction body of supplying gas, and also can be used for inhaling the liquor charging body.In the chemical plant, the jet pump station-service is in vacuumizing, so claim liquid-jet vacuum pump again.
The working fluid of jet pump can be a steam, also can be liquid.The prior steam jet pump is the single-stage jet pump, and its working procedure is that working steam under high pressure sprays from nozzle with very high speed, and in course of injection, the static energy of steam changes kinetic energy into, produces low pressure, from suction port gas is sucked.Get into diffusing tube after gas that sucks and the vapor mixing, speed reduces gradually, and pressure increases, then from extruding a mouthful discharge.
Jet pump simple structure, compactness do not have movable part, but its efficient is very low; Steam consumption is big, uses so generally make vacuum pump more, and does not use as conveying equipment; Because the fluid of being carried mixes with working fluid, thereby makes its application area receive certain limitation.
Summary of the invention
In order to solve the problem of above existence, the invention discloses a kind of three grades of vapor pumps, this jet pump is that several jet pumps are together in series, and can obtain higher degree of vacuum.
This vapor pump comprises first order jet pump, second level jet pump and third level jet pump, and first order jet pump upper end is laterally connecting the gas access pipeline; Vertically connecting steam line; The lower end of first order jet pump is connected the first condenser lower end, and jet pump upper end in the second level is connected first upper end of condenser, and the lower end is connected the second condenser lower end; Third level jet pump upper end is connected second upper end of condenser, and the lower end is connected the 3rd condenser lower end.
The upper end of said condenser is connected with intake pipe respectively.
The upper end of said second level jet pump and third level jet pump is being connected steam line respectively.
Said steam inlet channel end is provided with allots jet pump.
Be connected with a secondary injection pump between said gas access pipeline and steam line.
The positive lower end of said condenser is provided with discharge tube, and discharge tube is connected in the tank.
The present invention connects the prior steam jet pump, and sets up dexterously and discharge jet pump and secondary injection pump, reaches stronger degree of vacuum.

Fig. 1 is a structural representation of the present invention,
Accompanying drawing shows tabulation: 1-intake pipe, 2-discharge jet pump, 3-steam line, 4-third level jet pump; 5-second level jet pump, 6-secondary injection pump, 7-gas access pipeline; 8-first order jet pump, 9-the first condenser, 10-the second condenser; 11-tank, 12-discharge tube, 13-the three condenser.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further illustrate the present invention.
Fig. 1 is a structural representation of the present invention, as can be seen from the figure, and vapor pump; Comprise first order jet pump 8, second level jet pump 5 and third level jet pump 4, first order jet pump 8 upper ends are laterally connecting gas access pipeline 7, are vertically connecting steam line 3; The lower end of first order jet pump 8 is connected first condenser, 9 lower ends, and jet pump 5 upper ends in the second level are connected first condenser, 9 upper ends, and the lower end is connected second condenser, 10 lower ends; Third level jet pump 4 upper ends are connected second condenser, 10 upper ends; The lower end is connected the 3rd condenser 13 lower ends, and the upper end of condenser is connected with intake pipe 1 respectively, and the upper end of second level jet pump 5 and third level jet pump 4 is being connected steam line 3 respectively; Steam line 3 entry ends are provided with discharges jet pump 2; 3 of gas access pipeline 7 and steam lines are connected with a secondary injection pump 6, and the positive lower end of condenser is provided with discharge tube 12, and discharge tube 12 is connected in the tank 11.
Working steam is introduced into first order jet pump 8 through the steam inlet with the gas that is sucked by the gas access; Mixed gas makes vapor condensation through condenser; Gas then gets into second level jet pump 5; Then, sequentially through second condenser 10, third level jet pump 4 and the 3rd condenser 13, discharge by discharging jet pump 2 at last.Secondary injection pump 6 is parallelly connected with main jet pump, and in order to increase toggle speed, when system reached the degree of vacuum of appointment, secondary injection pump 6 can cut off in circuit.Condensed fluid in each condenser and cooling water current-sharing are gone in the tank 11.
