Abstract

The utility model provides a multi-nozzle steam ejector, which comprises nozzles, a receiving chamber, a mixing chamber, a throat pipe and a pressurization chamber, wherein working fluid inlets are formed on the nozzles; the receiving chamber is provided with an ejection fluid inlet; the receiving chamber, the mixing chamber, the throat pipe and the pressurization chamber are sequentially connected with one another along the axis; and a plurality of nozzles are arranged in the receiving chamber in parallel. According to the multi-nozzle steam ejector, high-pressure steam can be effectively divided and can be uniformly mixed with extracted low-pressure steam, so that noise produced by mixing and colliding of the high-pressure steam and the low-pressure steam is reduced; and the multi-nozzle steam ejector has functions of environment friendliness and noise reduction.

Description

A kind of multiinjector formula steam jet ejector
Technical field
The utility model relates to a kind of steam jet ejector, especially relates to a kind of multiinjector formula steam jet ejector.
Background technique
Sparger is that the vacuum of utilizing fluid to transmit energy and quality obtains device, and in this device, two fluid streams of different pressures are mixed each other, and energy interchange takes place, to form the fluid-mixing of one pressure placed in the middle.Fluid-mixing is divided into gas (steam) phase, liquid phase, or the mixture of gas (steam), liquid and solid.Before the inletting device, the higher the sort of medium of pressure is called working medium, and working medium stream is called working fluid.Working fluid comes out from nozzle with very high speed, gets into the receiving chamber of sparger, and takes away the lower medium of pressure before sparger.The fluid that is pulled away is called driving fluid.Usually in sparger, be that potential energy or the heat energy that working fluid takes place changes kinetic energy at first.The kinetic energy of working fluid, a part is passed to driving fluid.Along in the sparger process of flowing, the speed of fluid-mixing is balanced gradually, so the kinetic energy of fluid-mixing changes potential energy or heat energy on the contrary into.The industry such as vacuum station, vacuum brickmaking, building foundation pit precipitation, draining, oil, environmental protection that is widely used in light industry, chemical industry, chemistry, pharmacy, vacuum smelting, sugaring, salt manufacturing, monosodium glutamate, chemical fibre, papermaking, food, plastic, rubber, pottery, big-and-middle-sized hospital and industrial enterprise.
Steam jet ejector also is steam jet heat pump; It is to be power with the high pressure steam, utilizes the available energy of high pressure steam throttling, improves the pressure of low pressure steam; Put the low pressure steam of mistake with the high pressure steam energy recovery; Reclaim the flash steam of condensed water in high temperature etc., thereby, reach obvious energy-saving effect the integrated steam using of different brackets pressure.Be widely used in weaving, papermaking, oil, thermoelectricity etc. are with in the industry of steam as power, mainly are used for promoting vapor recycle, improve low pressure steam pressure.
Existing steam jet ejector generally is 1 pair of diffusion chamber 5 of a nozzle, and is as shown in Figure 1.The steam jet ejector of this structure tends to exist high pressure steam to can not get shortcomings such as effective shunting, noise be bigger in use.
The model utility content
For addressing the above problem, the utility model provides a kind of multiinjector formula steam jet ejector.
A kind of multiinjector formula steam jet ejector; Comprise nozzle, receiving chamber, mixing chamber, trunnion and diffusion chamber; Described nozzle is provided with Working-fluid intaking, and described receiving chamber is provided with the driving fluid inlet, and described receiving chamber, mixing chamber, trunnion, diffusion chamber connect along axle in order; Described nozzle is a plurality of nozzles, and described a plurality of nozzles are set in parallel in the receiving chamber.
Preferably, described diffusion chamber is a flow area enlarged configuration gradually.
Preferably, described driving fluid inlet is located at the receiving chamber bottom.
The utility model can make high pressure steam effectively shunted, and is taken out low pressure steam with quilt simultaneously and evenly mixes, and the noise that has produced when having reduced two bursts of vapor mixing collisions of high low pressure has the environment-friendly noise reduction effect.
Description of drawings
Fig. 1 is the structural representation of existing technology steam jet ejector.
Fig. 2 is the structural representation of the utility model.
Embodiment
As shown in Figure 2; A kind of multiinjector formula steam jet ejector comprises nozzle 1, receiving chamber 2, mixing chamber 3, trunnion 4 and diffusion chamber 5, and described nozzle 1 is provided with Working-fluid intaking; Described receiving chamber 2 is provided with the driving fluid inlet; Described receiving chamber 2, mixing chamber 3, trunnion 4, diffusion chamber 5 connect along axle in order, and described nozzle 1 is a plurality of nozzles, and described a plurality of nozzles are set in parallel in the receiving chamber 2.
Described diffusion chamber 5 is a flow area enlarged configuration gradually.Described driving fluid inlet 6 is located at receiving chamber 2 bottoms.
During use, high pressure steam is effectively shunting in three nozzles 1, because flow area diminishes gradually, steam flow rate increases gradually, and the pressure potential of steam gradates and is kinetic energy, and pressure reduces gradually.After high pressure steam passes through nozzle 1; Reach high speed in nozzle 1 outlet, most of pressure potential is converted into kinetic energy, and vapor pressure is reduced to below the low pressure exhaust steam pressure; Form local negative pressure relatively, flash steam is drawn into receiving chamber 2 from driving fluid inlet 6.Two strands of coaxial fluids carry out full and uniform mixing and speed and balancing energy in mixing chamber 3, in the outlet of mixing chamber 3, set up even velocity field and energy field; Form the high-speed vapor stream of stable uniform, after vapor stream gets into diffusion chamber 5 through trunnion 4, along with the expansion gradually of flow area area; Steam flow rate reduces gradually, and steam kinetic energy gradates and is potential energy, and pressure is restored gradually; When reaching diffusion chamber 5 ends, reach the desired pressure of technology.
