Abstract
A pressurizing heater for steam-liquid fluid re-circulated in a supersonic speed consists of a steam nozzle and an annular nozzle connected with an inlet of a mixing chamber, the annular nozzle connected with cold-water pipelines and sleeved around the steam nozzle to form a combined nozzle, which is connected with cold-water pipelines via a re-circulating pipe and a control valve. A venturi structure is used in the mixing chamber. The re-circulating pipe and valve regulate output of hot water flow according to loads on the system, so that self-adaptable hot water supply achieves.
Description
Technical field
The invention belongs to by contacting directly with other fluid that pumping fluid (F04F) directly contacts with heat exchange medium mutually the not heat-exchange apparatus of chemical reaction (F28C) technical field, be specifically related to heat energy to the recycling supersonic speed stream-liquid two-phase flow of the mechanical energy conversion heating equipment that boosts.
Background technique
The supersonic speed stream-liquid two-phase flow heating equipment that boosts is to utilize the kinetic energy of high velocity vapor stream to mix with supercooled water to form supersonic speed vapour-liquid two-phase mixed flow, produces condensation shock, pressure rising becoming hot water after passing through the variable cross section passage.The supersonic speed stream-liquid two-phase flow heater that boosts has that simple in structure, reliable, boost capability is strong, the heat exchange efficiency advantages of higher, is with a wide range of applications.But the existing supersonic speed stream-liquid two-phase flow heating equipment that boosts regularly has the characteristics of flow setting type at intake condition and structural parameter one, can not effectively regulate the hot water service flow according to the load variations of application system, and application area is restricted.
Summary of the invention
The object of the present invention is to provide a kind of hot water service flow to regulate automatically according to the load variations of application system, and the effective recycling supersonic speed stream-liquid two-phase flow of the aggrandizement apparatus hot water service flow adjustment range heating equipment that boosts.
For achieving the above object, the technical solution used in the present invention is: comprise and the first convergent steam nozzle and the annular water spray that are connected of the inlet of the mixing chamber of flaring again, the annular water spray that links to each other with cold water pipe is arranged on the periphery of steam nozzle, be characterized in that the outlet of mixing chamber also is connected with cold water pipe by recirculation pipe and the control valve that is arranged on the recirculation pipe.
Another characteristics of the present invention are: mixing chamber is that internal surface adopts fairshaped axisymmetric rotation body structure.
Because the present invention has increased by one section recirculation pipe between mixing chamber outlet and cold water pipe, and control valve is housed on recirculation pipe, make the present invention can regulate the flow of outlet hot water, thereby make the present invention have the adaptivity of hot water service flow according to the needs of system loading.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present invention.
Fig. 2 is a fundamental diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and working principle are described in further detail.
Referring to Fig. 1, the present invention includes a first convergent again the flaring internal surface adopt the mixing chamber 4 of fairshaped axisymmetric rotation body structure, the inlet of mixing chamber 4 is connected with steam nozzle 1 and annular water spray 3, the annular water spray 3 that links to each other with cold water pipe 2 is arranged on the periphery of steam nozzle 1, and the outlet of mixing chamber 4 also is connected with cold water pipe 2 by recirculation pipe 5 and the control valve 6 that is arranged on the recirculation pipe 5.Inner member of the present invention and external component are all taked embedded mounting type, are convenient to loading and unloading and change parts.Steam via convergent-divergent after steam nozzle 1 becomes the supersonic speed steam flow, in mixing chamber 4 with the cold water mix that enters by water spray 3, be mixed into uniform supersonic speed stream-liquid two-phase flow before arriving mixing chamber 4 throats, after mixing chamber 4 throats form condensation shock, pressure improves and becomes single-phase hot water, and the back of further boosting in gradually expanding section forms high-pressure water heating.The hot water flow that needs when the external world is during less than outlet hot water flow of the present invention, and outlet pressure of the present invention raises, and unnecessary hot water flows into recirculation pipes 5 through control valve 6, and the cold water mix with in the cold water pipe 2 enters mixing chamber 4 once more.Under the constant situation of flow of inlet water of the present invention, rate of discharge but can change along with the change of recirculating mass, thereby makes device have the adaptive-flow characteristic, and the adaptive capacity of using system loading is improved, and application area enlarges.
Referring to Fig. 2, the supersonic airstream that the present invention forms after utilizing high pressure steam to expand through supersonic speed steam nozzle 1 is as power source, in variable cross section mixing chamber 4, directly contact the back and form ultrasonic stream-liquid two-phase flow with the low pressure current, under the situation of constricted flow plug, produce condensation shock, realize pressure jump, obtain considerably beyond the high-pressure water flow of inlet steam pressure in 4 outlets of variable cross section mixing chamber, thereby realize increasing substantially the purpose of hydraulic pressure, thereby essence is to utilize a part of available energy in the heat that vapor condenses discharges to be converted into the pressure that mechanical work improves water.And existing supersonic speed stream-liquid two-phase flow not being both between the outlet of device and cold water pipe of heater maximum of boosting increases by one section recirculation pipe, and control valve is housed, thereby makes the present invention to regulate the outlet hot water flow according to the needs of system loading.
