Abstract
The recycling supersonic pressure boosting and heating system for gas/liquid two-phase flow of the utility model comprises a vapor nozzle and an annular water nozzle connected with the inlet of a convergent-and-divergent hybrid chamber. The annular water nozzle connected with a cold water pipe is arranged at the periphery of the vapor nozzle; the outlet of the hybrid chamber connects with the cold water pipe through a recirculator and the control valve disposed on the recirculator. Because a recirculator is arranged between the outlet of the hybrid chamber and the cold water pipe in the utility model and a control valve is arranged on the recirculator, the utility model has the advantage of regulating the flow quantity of hot water at the outlet according to the requirement of system load. In this way, the utility model has the characteristic of self-adaptability for the hot water supply flow quantity.
Description
Technical field
The utility model 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, is 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 purpose of this utility model 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 adopted in the utility model 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 utility model are: mixing chamber is that internal surface adopts fairshaped axisymmetric rotation body structure.
Because the utility model 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 utility model can regulate the flow of outlet hot water, thereby make the adaptivity that the utlity model has the 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 utility model;
Fig. 2 is a fundamental diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and working principle are described in further detail.
Referring to Fig. 1, the utility model comprise 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 utility model 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 utility model, and outlet pressure of the present utility model 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 the utility model flow of inlet water, 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 utility model 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 utility model to regulate the outlet hot water flow according to the needs of system loading.
