Abstract
The utility model relates to a jetting type heat pump without a receiving chamber. The jetting type heat pump comprises a nozzle, a mixing chamber, a throat pipe and a pressurization chamber, wherein the mixing chamber, the throat pipe and the pressurization chamber are sequentially connected along a shaft; an air suction port is formed at the bottom of the mixing chamber; and the nozzle is arranged in the mixing chamber. The structure of the jetting type heat pump is simplified; the production cost is saved; the coaxiality of the heat pump can be well guaranteed; and the using effect is good.
Description
Technical field
The utility model relates to a kind of jet-type heat pump, especially relates to a kind of jet-type heat pump that does not have receiving chamber.
Background technique
The jet-type heat pump is a kind of jet turbulent fluctuation diffusion of utilizing, with high-pressure liquid injection low-pressure fluid and pass can mass transfer fluid machinery and mix reaction equipment.Have advantages such as simple in structure, easy processing, movement-less part, reliable operation, cost be low, convenient for installation and maintenance; And driven fluid do not had strict demand, be widely used in industries such as water conservancy and hydropower, petrochemical industry, metallurgical light textile, nuclear energy uses, Aero-Space, farming and animal husbandry.
Existing jet-type heat pump generally comprises nozzle 1, receiving chamber 6, mixing chamber 2, trunnion 3 and diffusion chamber 4, and is as shown in Figure 1.The coaxality of the jet-type heat pump of this structure can not get good assurance, influences using effect.
The model utility content
For addressing the above problem, the utility model provides a kind of jet-type heat pump that does not have receiving chamber.
A kind of jet-type heat pump that does not have receiving chamber; Described jet-type heat pump comprises nozzle, mixing chamber, trunnion and diffusion chamber; Described mixing chamber, trunnion and diffusion chamber are connected along axle in order, and described mixing chamber bottom is provided with intakeport, and described nozzle is located in the mixing chamber.
Preferably, described diffusion chamber is a flow area enlarged configuration gradually.
The utility model has not only been simplified jet-type heat pump structure, has practiced thrift cost of production, and more can guarantee the coaxality of heat pump, and using effect is good.
Description of drawings
Fig. 1 is the structural representation of jet-type heat pump in the existing technology.
Fig. 2 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further, but the protection domain of the utility model is not limited to this.
As shown in Figure 2; A kind of jet-type heat pump that does not have receiving chamber; Described jet-type heat pump comprises nozzle 1, mixing chamber 2, trunnion 3 and diffusion chamber 4; Described mixing chamber 2, trunnion 3 and diffusion chamber 4 are connected along axle in order, and described mixing chamber 2 bottoms are provided with intakeport 5, and described nozzle 1 is located in the mixing chamber 2.Described diffusion chamber 4 is a flow area enlarged configuration gradually.
During use, high pressure steam is in nozzle 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; Vapor pressure is reduced to below the low pressure exhaust steam pressure, forms local negative pressure relatively, flash steam directly is drawn into through intakeport 5 fully mixes in the mixing chamber 2 and speed and balancing energy; In the outlet of mixing chamber 2, set up even velocity field and energy field, form the high-speed vapor stream of stable uniform; Get into diffusion chamber 4, along with the expansion gradually of flow area area, steam flow rate reduces gradually; Steam kinetic energy gradates and is potential energy; Pressure is restored gradually, when reaching diffusion chamber 4 ends, reaches the desired pressure of technology.
