Description
Technical field
What the present invention relates to is a kind of experimental provision of flash distillation.
Background technology
The liquid of uniform temperature is exposed to suddenly lower than under the environment corresponding to saturated vapour pressure at this temperature, and liquid can not make all sensible heats be stored in wherein, so unnecessary heat discharges in the mode of evaporation latent heat, causes flass.Due to flash distillation in storage heater peculiar to vessel, flash boiling spray and food, desalinization, medicine is dry and the extensive use in the field such as cooling, the geothermal energy of the cooling and nuclear reactor of sterilization, space shuttle high-temperature part and power generation with marine energy, people are more and more extensive to its research in recent years, the flash tank that in experiment, some scholars adopts is at present transparent material, can meet well like this needs of observation, but transparent material bearing capacity is low, cannot study the flass under mesohigh.Also have scholar to adopt cylindrical shape stainless steel cylinder, then on cylindrical shell, open form, for keeping integral rigidity, the size of form is restricted, and observation effect is undesirable, and bearing capacity is also limited.Industrial flash tank bearing capacity is better, but does not take and daylighting window, cannot observe flass, measurement device in cylindrical shell is few and be traditional measurement equipment, equipment reaction speed is slow, and poor sensitivity can not record the acute variation of temperature and pressure in flash process well.
Summary of the invention
The object of the present invention is to provide can be used for investigating in the flass of different liquids and working medium and insert a kind of hp flash drum of foreign matter on the impact of flass.
The object of the present invention is achieved like this:
A kind of hp flash drum of the present invention, it is characterized in that: comprise cylindrical shell, be arranged on cylindrical shell top upper flange, be arranged on the low head of cylinder body bottom, the both sides, front and back of cylindrical shell arrange respectively takes form and daylighting form, taking form and daylighting form is arranged symmetrically with, the left side of cylindrical shell arranges relief valve connection, water intaking valve interface, inlet valve interface, optical fiber is set on the right side of cylindrical shell and wire is drawn flange, on described upper flange, have pressure outlet and exhaust-valve interface, on described low head, have discharging valve interface.
The present invention can also comprise:
1, described cylindrical shell is the square-outside and round-inside structure that monoblock forging process forms.
2, described form height is set to meet observation and the investigation of different liquid level on flass impact of the extreme position on developing under liquid flashes wave direction.
Advantage of the present invention is: flash tank of the present invention adopts the structure of square-outside and round-inside, has bearing capacity strong, can do the flash distillation experiment of mesohigh operating mode, has large form simultaneously, can be for observing the condition that facilitates.Flash tank uses test optical fiber temperature and pressure, has reaction speed fast, highly sensitive, measures accurately, and volume is little affects the advantages such as little to water body.Flash tank is provided with foil gauge, can follow the tracks of the variation of stress in the barrel wall in flash process, to carry out the analysis of fatigue of cylindrical shell in dynamic flash process, and contrasts with stress fiber grating, theory analysis and numerical simulation result.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is A-A cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing, for example the present invention is described in more detail:
In conjunction with Fig. 1～2, flash tank of the present invention, as shown in Figure 1, it comprises cylindrical shell 1, upper flange 9, low head 3 has exhaust-valve interface 8 and pressure outlet 7 on upper flange 9, has discharging valve interface 3 on low head 2; Right upper portion at cylindrical shell 1 has relief valve connection 6, and middle part has water intaking valve interface 5, and bottom has inlet valve interface 4; Cylindrical shell left side is provided with optical fiber and wire is drawn flange 10; Before cylindrical shell, have observation form 11, the back side has daylighting form.
Described cylindrical shell is carbon steel 20MnMo material, by monoblock forging process, formed, 163 millimeters of cross section internal diameters are high 1000 millimeters.According to GB150-1998 < < GB150-1998 > >, flash chamber is carried out to intensity calculating and structure optimization, cylindrical shell cross section square-outside and round-inside.
Described cylindrical shell front portion has and takes form, rear portion has daylighting form, and two form full symmetrics are convenient to the layout of light path like this.Form material is high temperature high voltage resistant composite, can meet the requirement of intensity, can meet visual requirement again.Form height is 510 millimeters, and width is 80 millimeters.Form width can guarantee that through calculating ccd video camera shooting angle reaches to maximum cross-section, and form height can meet observation and the investigation of different liquid level on flass impact of the extreme position on developing under liquid flashes wave direction.
Described cylindrical shell left side is equipped with respectively relief valve connection, water intaking valve interface and inlet valve interface from top to bottom.
Flange is installed at described cylindrical shell top, and bottom connects low head.
Described cylindrical shell right side has optical fiber and wire to draw flange, optical fiber and foil gauge wire need, through a flanged (FLGD) seal, in tetrafluoroethene glue embedding for seal hollow space, then add one deck rubber blanket in the above herein, with a flange, rubber blanket is compressed again, to guarantee good sealing.
On described upper flange, have exhaust-valve interface and pressure outlet.
On described low head, have discharging valve interface, before experiment starts, a thermocouple can be installed on this discharging valve interface, insert in water body, so that temperature test optical fiber is checked, after experiment starts, for avoiding thermocouple to insert the impact on flass itself in water, taken out, now discharging valve interface can play the effect discharging water after experiment completes.
In addition, the thickness of form place cylindrical shell (containing visor) is through calculating and model experiment, guaranteeing that camera lens presses close to visor and can photograph under the prerequisite at place, maximum cross-section of cylindrical shell, is 78 millimeters.
Experiment is when carry out, and injects the water of object height first from water intaking valve interface to cylindrical shell 1, by back pressure system, cylinder internal pressure is adjusted to goal pressure slightly high, and the valve of then closing between back pressure system and flash tank connects, and regulates back pressure system to specifying back pressure.By inlet valve interface 4, steam is passed in cylindrical shell 1, cool water heating is slightly high to target temperature.Now open the control valve between flash tank and back pressure system, and change up soon pass magnetic valve for several times, the steam that utilization flashes off is by Bas Discharged in water, because making water temperature, flash distillation meeting reduces, again close control valve and magnetic valve, continuation is filled with steam from inlet valve interface 4, stops filling vapour after reaching goal pressure and temperature.Open light source, video camera and test data collection device, adjust control valve opening, open magnetic valve, flash distillation experiment starts.
Flash tank of the present invention test macro used comprises optical fiber and foil gauge, test optical fiber temperature, pressure and stress, and foil gauge test stress, optical fiber and foil gauge signal are all drawn flange 10 from optical fiber and wire and are drawn.
This flash tank not only can carry out the flash distillation experiment of common distilled water, can also be used to investigate in the flass of different liquids and working medium insert the impact of foreign matter on flass.
