Background technique
The jetting extract system is the corollary equipment of extensive use in the middle-size and small-size thermal power plant, plays an important role at aspects such as guaranteeing necessary vacuum requirement of the normal operation of steam turbine and raising steam turbine power generation efficient.Conventional jetting extract system is made up of jetting case, water-jet pump, water jet air ejector and corresponding valve and pipeline, and its system layout freedom, dispersion are for turbine condenser Design of Vacuum System and installation have brought all inconvenience.Simultaneously, (exhaust steam pressure is 0.008MPa because the non-condensible gas of extracting out from gas condensating device has uniform temperature, exhaust temperature is 41.5 ℃), after it is brought into the jetting case with working solution mixing heat release, to when long-play, cause the water temperature of jetting case to raise, thereby cause the exhaust capacity reduction of extract system, and influence the reduction of condenser vacuum thereupon, so that cause generating efficiency to descend.Usually the method that addresses this problem is to pour into low temperature water to reach the cooling purpose in the jetting case, still, because the jetting extract system is the closed-loop water system of no water consumption, so the working solution of redundance will be by the flow-off discharging of jetting case top.A large amount of wastes of water resources like this, have just been caused.
The model utility content
The purpose of this utility model is exactly fundamentally to solve the problems of the technologies described above, and a kind of integrated cold mould jetting air extractor that closes is provided for this reason, arranges dispersion to overcome traditional jetting extract system, inconvenience and a large amount of waste water resources or the like defective is installed.
The technical solution of the utility model is:
A kind of integrated cold mould jetting air extractor that closes, comprise water-jet pump, the input end of described water-jet pump connects the jetting cyclic water tank by water pipe, described jetting delivery side of pump is by the input end of water-jet pump water pipe connection jetting vacuum pump, and the equipment interface on described jetting vacuum delivery side of pump and the described jetting cyclic water tank links; Be provided with the circulation cooling structure that its two ends connect water-cooling tube respectively in the described cyclic water tank; Described jetting vacuum pump also connects check valve, and described check valve connects vapour condenser by the condenser vacuum pipe.
The beneficial effects of the utility model are:
(1) the dispersed placement form of former steam turbine jetting extract system is integrated, improved whole equipment, reduced the occupation of land of equipment, simplified system has shortened design, the installation period of engineering.
(2), make the working water water temperature stability in rated range by setting up cooling tube bundle in the jetting case.Guarantee the exhaust capacity of jetting air extractor and the stability of bleeding on the one hand, because the cold circuit type of cooling is closed in employing, saved water resources on the other hand, avoided waste.
(3) control of novel jetting extract system by the control mode of control DCS in traditional split introducing, becomes the equipment centralized control of total system, and is concentrated by being distributed to, and improved the whole controlling level of device.
Description of drawings
Accompanying drawing is a structural representation of the present utility model;
Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 has illustrated formation situation of the present utility model.
As seen from the figure, the integrated cold mould jetting air extractor that closes of the present utility model, comprise water-jet pump 1, the input end of described water-jet pump 1 connects jetting cyclic water tank 2 by water pipe, the output terminal of described water-jet pump 1 is by the input end of water-jet pump water pipe 5 connection jetting vacuum pumps 3, and the equipment interface on the output terminal of described jetting vacuum pump 3 and the described jetting cyclic water tank 2 links; Be provided with the circulation cooling structure 8 that its two ends connect water-cooling tube respectively in the described cyclic water tank 2; Described jetting vacuum pump 3 also connects check valve 4, and described check valve 4 connects vapour condenser 7 by condenser vacuum pipe 6.
Working procedure of the present utility model is as follows:
High pressure water by water-jet pump 1 enters jetting vacuum pump 3 by water-jet pump water pipe 5, and sprays at a high speed through the nozzle that is arranged on jetting vacuum pump 3 inside, so that potential energy is converted into kinetic energy.Because it is critical even overcritical that the effluxvelocity at described jetting vacuum pump 3 inwardly projecting orifice throats place can reach, so, can make the inside of described jetting vacuum pump 3 form the environment under low pressure that is similar to vacuum; Again because described condenser vacuum pipe 6 is connected the pressure lowest part of described jetting vacuum pump 3 by described check valve 4, so, can reach the purpose that described vapour condenser 7 vacuumizes.The purpose of described check valve 4 is installed on described jetting vacuum pump 3, is that the water suck-back that prevents from will work when described jetting vacuum pump 3 from breaking down enters vapour condenser 7.
The diffusing tube that in described jetting vacuum pump 3, mixes and together enter described jetting vacuum pump 3 inside by the fixed gas of extracting out in the described vapour condenser 7, vapour mixture with working solution, thereby its flow velocity is slowed down, pressure raises, and to enter jetting cyclic water tank 2 a little more than atmospheric pressure.Owing to be provided with circulation cooling structure 8 in the described cyclic water tank 2, and a termination of described circulation cooling structure 8 is received the water from water-cooling tube, and the other end is sent water back to water-cooling tube, so that the water of elevated temperature is cooled to operating temperature by described circulation cooling structure 8 gradually, simultaneously, on described jetting cyclic water tank 2, the chemistry filled water pipe is installed also, when the internal water quantity not sufficient of described jetting cyclic water tank 2, can carries out moisturizing by the chemistry filled water pipe.
