Abstract
The utility model provides an ejecting device for flash steam. The device comprises an ejecting bush, a flash steam inlet, an ejecting inlet pipe and an ejecting outlet pipe, wherein the ejecting inlet pipe is provided with a water inlet, the ejecting outlet pipe is provided with a water outlet, the water inlet end of the ejecting inlet pipe and the water outlet end of the ejecting outlet pipe are arranged outside the ejecting bush, the other end of the ejecting inlet pipe and the other end of the ejecting outlet pipe are arranged in the ejecting bush, the ejecting inlet pipe and the ejecting outlet pipe have the same central line, and the flash steam inlet is disposed in the side face of the ejecting bush and vertical to the central line of the ejecting inlet pipe. The ejecting device is characterized in that a cavity body of the ejecting inlet pipe is conical, a cavity body of the ejecting outlet pipe is horn-shaped, and a fluid connector is formed between the ejecting inlet pipe and the ejecting outlet pipe and is arrow-shaped. The ejecting device is installed on the rear side of a boiler so that the flash steam is easy to discharge from the boiler, pressure in the boiler is lowered, other fluids conveniently flow into the boiler, and therefore safety potential risks are reduced.
Description
Technical field
The utility model belongs to vacuum equipment technical field, relates in particular to a kind of lead-jetting device.
Background technique
Condensate recovering device is used for the recovery of the condensed water that fizzy mineral water heat exchanger or flow produce, and condensed water is high-quality water, and contains a large amount of heat energy, is one of important measures of energy-saving and water-saving so reclaim condensed water in steam heating system.It is by the regulator in the tank body, cavitation erosion cancellation element and special water pump, the complete enclosed that has realized high-temperature condensation water and high energy secondary vapour reclaims, dwindled the volume of collecting container, eliminate secondary vapour, stopped corrosion, but generally relied on vapor tension to discharge in using process, velocity ratio is slower, affects the recovery speed of condensate recovering device.In the supply channel of boiler, if vapor pressure is too high, water is difficult for entering in the boiler, and there is a potential safety hazard, this just need in time discharge steam, and lead-jetting device is to utilize a kind of high speed operation fluid (liquid or gas) to carry the fluid machinery of one other fluid medium, mixture is mixed fully, speed is even, and it is simple in structure, reliable operation, installation and maintenance are easy, can realize the suction pressurization of water (vapour), be convenient to the conveying of fluid, therefore in petrochemical industry, metallurgical, light industry, the heat enginnering fields such as electric power have broad application prospects.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of flash steam lead-jetting device, comprise the injection sleeve pipe, the flash steam entrance, injection enters pipe, injection goes out pipe, described injection enters pipe and is provided with water intake, described injection goes out pipe and is provided with water outlet, described injection enters the inlet end of pipe, the water outlet end that described injection goes out pipe is arranged on outside the described injection sleeve pipe, described injection enters pipe, the other end that described injection goes out pipe all is arranged in the described injection sleeve pipe, described injection enters pipe and goes out pipe with described injection identical center line is arranged, described flash steam entrance is arranged on described injection sleeve pipe side, and with described injection to enter the center line of pipe vertical, it is characterized in that the cavity geometry that described injection enters pipe is taper, the cavity geometry that described injection goes out pipe is tubaeform, described injection enters pipe, described injection goes out to form fluid interface between the pipe, described fluid interface be shaped as arrow-shaped.
The beneficial effects of the utility model are: injection enters the taper that is shaped as of pipe, is convenient to the injection of water, and the injection dynamics is larger, fluid interface is shaped as arrow-shaped, make fluid be convenient to enter injection and go out pipe, it is tubaeform that injection goes out being shaped as of pipe, is convenient to fluid and further mixes in the outflow process.In the boiler back the utility model is installed, can be made that the flash steam of generation is easier discharges in boiler, reduced the pressure in the boiler, be convenient to other fluid and enter boiler, and reduced potential safety hazard.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation.
Among the figure, 1, the injection sleeve pipe, 2, the flash steam entrance, 3, injection enters pipe, 4, injection goes out pipe, 5, fluid interface.
As shown in Figure 1, injection enters pipe 3 and is provided with water intake, injection goes out pipe 4 and is provided with water outlet, injection enters the inlet end of pipe 3, the water outlet end that injection goes out pipe 4 is arranged on outside the injection sleeve pipe 1, injection enters pipe 3, the other end that injection goes out pipe 4 all is arranged in the injection sleeve pipe 1, injection enters pipe 3 and goes out to manage 4 with injection identical center line is arranged, flash steam entrance 2 is arranged on injection sleeve pipe 1 side, and with injection to enter the center line of pipe 3 vertical, the cavity geometry that injection enters pipe 3 is taper, the cavity geometry that injection goes out pipe 4 is tubaeform, and injection enters pipe 3, injection goes out to form fluid interface 5 between the pipe 4, fluid interface 5 be shaped as arrow-shaped.
Example:
During use, water intake of the present utility model is connected with the water outlet of water pump, flash steam outlet on flash steam entrance 2 and the boiler is connected, flash steam and water are in 3 interior mixing of injection sleeve pipe, then through fluid interface 5, flow out along water outlet, the utility model can reduce the pressure in the boiler, is convenient to other fluid and enters boiler, has reduced potential safety hazard.
Above an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should belong within the patent covering scope of the present utility model.
