Referring to fig. 1 and 3, a dual fluid gasifier includes a finned tube 1, a dual fluid nozzle 2, and a gas phase booster tube 3, the dual fluid nozzle 2 being disposed on the finned tube 1; the two-fluid nozzle 2 comprises a liquid phase flow cavity 201, a gas phase flow cavity 202 and a jet hole 203, the gas phase booster pipe 3 is communicated with the gas phase flow cavity 202, the inlet of the finned tube 1 is communicated with the liquid phase flow cavity 201, and the liquid phase flow cavity 201 and the gas phase flow cavity 202 are communicated with the outlet of the finned tube 1 through the jet hole 203; when the gas pressure of the gas-phase medium is greater than the hydraulic pressure of the liquid-phase medium, the two-fluid nozzle 2 converts the mixture of the gas-phase medium and the liquid-phase medium into a mixture of the gas-phase medium and the atomized medium.
Wherein the liquid-phase medium and the gas-phase medium respectively flow in the two-fluid nozzle 2 separately from each other, but meet at the nozzle orifice 203 of the two-fluid nozzle 2. The liquid phase medium flows into the liquid phase flow cavity 201 of the two-fluid nozzle 2 from the finned tube 1 at the inlet end of the two-fluid gasifier (hereinafter referred to as gasifier) provided by the utility model, and the gas phase medium flows into the gas phase flow cavity 202 of the two-fluid nozzle 2 from the gas phase pressure increasing pipe 3; in the interior of the two-fluid nozzle 2, the liquid-phase medium and the gas-phase medium flow in the same direction, and the liquid-phase medium and the gas-phase medium are in an isolated state before being mixed; the liquid phase medium flows out from the liquid phase flow cavity 201, and the gas phase medium flows out from the gas phase flow cavity 202, and the liquid phase medium and the gas phase medium are mixed in a cavity close to the spray hole 203; when the gas pressure of the gas-phase medium is greater than the hydraulic pressure of the liquid-phase medium, the liquid-phase medium is converted into a mist medium when being sprayed out of the spray holes 203 under the flowing pressure of the gas-phase medium; the mixture of the atomized medium and the gaseous medium sprayed from the spray holes 203 flows along the direction from the two-fluid nozzle 2 to the outlet of the gasifier, and in the finned tube 1 in the direction, the atomized medium gradually forms a heat exchange state with the finned tube 1, so that the atomized medium is gradually converted into the gaseous medium.
It should be understood that after the liquid-phase medium absorbs the heat of the outside air in the vaporizer, the liquid-phase medium is transformed into a gas-phase medium, which is in two forms of the same substance, namely, a liquid state and a gas state of the same substance; the gas-phase medium transferred to the gas-phase flow chamber 202 of the two-fluid nozzle 2 through the gas-phase pressure increasing pipe 3 is the same as the liquid-phase medium flowing from the fin tube 1 into the liquid-phase flow chamber 201 of the two-fluid nozzle 2 in two forms of the same substance, that is, the same substance in the liquid and gas states. For example: the liquid phase medium is liquid oxygen, and after the liquid oxygen absorbs the heat of external air in the gasifier, the temperature of the liquid oxygen is raised to the boiling point, so that the liquid oxygen is converted into oxygen; similarly, the gas-phase medium delivered from the gas-phase pressurizing pipe 3 to the gas-phase flow chamber 202 of the two-fluid nozzle 2 should be oxygen.
It should be understood that the liquid medium is in a low-temperature liquid state, and the mist medium is also in a low-temperature liquid state, and the difference between the two is: the liquid medium is a continuous whole formed by gathering a plurality of liquid particles, and the mist medium is liquid particles which are mutually dispersed.
It should be noted that in the prior art gasifiers having only finned tubes 1, the liquid medium per unit volume can only be transformed into a gaseous medium in one of the sections of finned tubes 1. The utility model provides a two-fluid vaporizer, it is through the structure of gas phase booster pipe 3 and two-fluid shower nozzle for unit volume liquid medium changes vaporific medium under the atmospheric pressure effect of gas phase medium, and after unit volume liquid medium changed vaporific medium, the total volume of unit volume liquid medium kept unchanged, but its area of contact with the outside (especially refer to the liquid medium or the general surface area of vaporific medium) increase; the single atomized medium is liquid particles, has small mass and small volume, and can flow along with the flow of gas (especially gas phase medium from the gas phase booster pipe 3). Under the action of the air pressure of the gas-phase medium, the atomized medium and the multi-section finned tubes 1 can gradually form a heat exchange structure, so that the heat exchange area of the unit liquid-phase medium is enlarged after the unit liquid-phase medium is converted into the atomized medium.
Therefore, the two-fluid gasifier provided by the utility model has the advantages that the two-fluid nozzle and the gas phase pressure increasing pipe are arranged on the finned tube, so that the liquid phase medium from the finned tube is converted into the vaporous medium through the spray holes of the two-fluid nozzle under the air pressure action of the gas phase medium from the gas phase pressure increasing pipe; the mixture of the vaporous medium and the gas-phase medium flows in the finned tube from the double-fluid nozzle to the outlet direction of the gasifier together, the vaporous medium gradually forms a heat exchange area with the finned tube, and the heat exchange area formed by the liquid-phase medium and the finned tube in the gasifier in the prior art is larger than that formed by the liquid-phase medium and the finned tube, so that the technical problem that in the prior art, the contact area of the liquid-phase medium and the finned tube is small due to the small pipe diameter of the finned tube, and the heat exchange efficiency of the liquid-phase medium passing through the finned tube.
Further, referring to fig. 3, the gas-phase flow chamber 202 is disposed coaxially with the liquid-phase flow chamber 201; in the radial direction of the two-fluid nozzle 2, the gas-phase flow chamber 202 and the liquid-phase flow chamber 201 are spaced from each other; in the axial line direction of the two-fluid nozzle 2, the gas-phase flow chamber 202 and the liquid-phase flow chamber 201 communicate with the nozzle hole 203, respectively.
The gas-phase flow cavity 202 is arranged outside the liquid-phase flow cavity 201, so that the gas-phase medium applies pressure (gas pressure of the gas-phase medium) to the liquid-phase medium in the circumferential direction to the axial center line, and the liquid-phase medium is extruded by the pressure and then flows discontinuously, thereby being beneficial to converting the liquid-phase medium into a mist medium under the continuous gas pressure of the gas-phase medium and avoiding the accumulation of the liquid-phase medium in the two-fluid nozzle 2.
Further, the difference between the diameter of the gas phase flow chamber 202 and the diameter of the liquid phase flow chamber 201 is greater than or equal to the diameter of the liquid phase flow chamber 201.
The diameter of the gas-phase flow cavity 202 is larger than that of the liquid-phase flow cavity 201, so that only the gas-phase medium can flow into the gas-phase flow cavity 202 and join with the liquid-phase medium in the two-fluid nozzle 2; in practical applications, if the difference between the diameter of the gas-phase flow chamber 202 and the diameter of the liquid-phase flow chamber 201 is small, the gas pressure of the gas-phase medium may be affected by the small difference to cause insufficient gas pressure (or insufficient gas amount of the gas-phase medium). By enlarging the diameter of the gas-phase flow chamber 202 so that the difference between the diameter of the gas-phase flow chamber 202 and the diameter of the liquid-phase flow chamber 201 is at least equal to the diameter of the liquid-phase flow chamber 201, it can be ensured that the gas-phase medium has sufficient gas pressure (or the gas-phase medium has sufficient gas amount) to be mixed with the liquid-phase medium, and preferably, the difference between the diameter of the gas-phase flow chamber 202 and the diameter of the liquid-phase flow chamber 201 is larger than the diameter of the liquid-phase flow chamber 201, thereby avoiding the situation of insufficient gas pressure (or insufficient gas amount of the gas-phase medium).
Further, referring to fig. 3, a plurality of nozzle holes 203 are provided on the two-fluid nozzle 2, and the axial center line of any one nozzle hole 203 is the same as that of the two-fluid nozzle 2, and the distances between the adjacent 2 nozzle holes 203 are the same.
The plurality of nozzle holes 203 are arranged at the same pitch with respect to the axial center line of the two-fluid nozzle 2, which is advantageous for improving the machining accuracy of the two-fluid nozzle 2 and reducing the machining cost. In addition, the shape of the mist medium sprayed by all the spray holes 203 with the same interval is approximately circular; the shape of the mist medium sprayed from the plurality of spray holes 203 with unequal intervals is irregular; therefore, the plurality of orifices 203 are arranged at the same pitch, which is beneficial to controlling the spraying shape of the mist medium, so that the mist medium is in a uniform spraying state.
Further, referring to fig. 1, an inlet of the gas phase booster pipe 3 is connected to an outlet of the finned tube 1 in a three-way shape.
The gas-phase medium produced by the vaporizer itself flows into the gas-phase flow chamber 202 of the two-fluid nozzle 2 through the gas-phase pressurizing pipe 3, and the gas pressure of the gas-phase medium is used to pressurize the liquid-phase medium, so that the liquid-phase medium is converted into a mist-like medium through the two-fluid nozzle 2. The arrangement mode has the advantages of simple structure, small occupied space and low cost.
It should be understood that before the gaseous medium produced by the gasifier itself is fed to the two-fluid nozzle 2 through the gas pressure increasing pipe 3, the liquid-phase medium flows from the finned tube 1 into the two-fluid nozzle 2, then flows out from the spray holes 203 of the two-fluid nozzle 2, and flows along the subsequent finned tube 1 to be converted into the gaseous medium; at this stage, it can be regarded that the liquid phase medium forms a heat exchange structure only through the finned tube 1, and the two-fluid nozzle 2 only plays a role of a channel; after that, the gas-phase medium may be fed into the two-fluid nozzle 2 through the gas-phase pressurizing pipe 3.
Preferably, a booster pump (not shown) is provided in the gas-phase booster duct 3, thereby preferably increasing the pressure of the gas-phase medium.
In addition, besides the aforementioned scheme of conveying the gas-phase medium produced by the gasifier itself to the two-fluid nozzle 2 through the gas-phase pressure increasing pipe 3, the scheme of conveying the gas-phase medium in a remote gas-phase medium gas storage tank to the two-fluid nozzle 2 through the gas-phase pressure increasing pipe 3 can also be adopted; alternatively, it is also possible to use at least two gasifiers in combination, at least one of which provides the remaining gasifiers with a gaseous medium and this gaseous medium is conveyed to the two-fluid nozzle 2 through the gas pressure inlet 3.
Further, referring to fig. 1 and 2, the gasifier further comprises a pressure increasing barrel 4, the two-fluid nozzle 2 is arranged in the pressure increasing barrel 4, and the inner diameter of the pressure increasing barrel 4 is larger than or equal to the spraying diameter of the two-fluid nozzle 2;
the finned tube 1 and the gas phase pressurizing tube 3 which are communicated with the liquid phase flow cavity 201 are respectively in sealing connection with the pressurizing cylinder 4, and the finned tube 1 which is communicated with the jet hole 203 is in sealing connection with the pressurizing cylinder 4.
In the foregoing, it is mentioned that the atomized medium ejected from the two-fluid ejection group is uniformly ejected, but in actual use, the diameter of the atomized medium is larger than the inner diameter of the finned tube 1, so that the excessive atomized medium is ejected on the inner tube wall of the finned tube 1, and is converged again to be converted into a liquid-phase medium. By providing the pressure increasing cylinder 4, particularly when the inner diameter of the pressure increasing cylinder 4 is larger than the spray diameter of the two-fluid nozzle 2, the spray area of the two-fluid nozzle 2 can be enlarged, thereby reducing or avoiding the occurrence of the situation that the atomized medium is sprayed on the inner wall of the pressure increasing cylinder 4 (i.e., the atomized medium is sprayed on the inner wall of the finned tube 1) and is converged again to be changed into the liquid-phase medium.
Further, the vaporizer further comprises a regulating valve and a controller (not shown in the figure), wherein the regulating valve is arranged on the finned tube 1 connected with the liquid phase flow cavity 201 and is connected with the controller through a communication cable; the timing function module of the controller outputs a control signal according to a preset condition, and the control signal is transmitted to the regulating valve through the communication cable.
The regulating valve is used for regulating the flow of the liquid-phase medium and is realized by setting the opening degree of the regulating valve to different opening degrees; the controller is used for controlling the regulating valve to regulate the opening degree of the regulating valve.
When the gasifier is used for a long time, a part of the finned tubes 1 are in a low-temperature state for a long time, so that the finned tubes 1 tend to be in an icing state or are already iced, and at the moment, the opening degree of the regulating valve is in a reduced state by sending out a control signal for reducing the opening degree through the controller, so that the flow of a liquid phase medium is reduced; the liquid phase medium with reduced flow rate continuously flows into the finned tube 1 or the double-fluid nozzle 2, so that the gasifier is ensured to continuously work; in addition, since the flow rate of the liquid-phase medium is reduced, the amount of heat required for heat exchange of the liquid-phase medium in the inner chamber of the vaporizer is relatively reduced, so that the finned tube 1 is brought into a temperature-raised state by the heat of the outside air.
In the practical use of the gasifier, the gas-phase medium produced by the gasifier needs to be used immediately, and most of the gas-phase medium needs to be output to devices such as a gas storage tank and the like, so that the gas-phase medium flowing into the two-fluid nozzle 2 is reduced; at the moment, a control signal for increasing the opening degree is sent out by the controller, so that the opening degree of the regulating valve is in an increased state, and the flow of the liquid-phase medium is increased; the liquid phase medium with increased flow continuously flows into the finned tube 1 or the two-fluid nozzle 2, so that the gas amount of the gas phase medium produced by the gasifier is increased, and the pressure (or the gas amount of the gas phase medium) of the gas phase medium required by the two-fluid nozzle 2 can be better ensured.
Therefore, through setting up governing valve and controller, make the utility model provides a two fluid formula gasifiers presents the controllable state in the certain limit, can adjust according to actual production needs.
Further, referring to fig. 3, an impingement portion 204 is provided in the inner cavity of the two-fluid nozzle 2; in the axial lead direction of the two-fluid nozzle 2, the impact part 204 and the liquid phase flow cavity 201 are coaxially arranged, and a space is reserved between the impact part 204 and the outlet of the liquid phase flow cavity 201; in the radial direction of the two-fluid nozzle 2, a space is left between the edge of the striking portion 204 and any one of the nozzle holes 203.
Wherein the liquid phase medium flowing out of the liquid phase flow chamber 201 first impinges on the impact plate, and the liquid phase medium generates a direction-changing and dispersed flow along the surface of the impact plate by the impact plate, so that the liquid phase medium is 'broken up' by the impact plate, and the liquid phase medium is changed from large particles to small particles. The liquid phase medium tends to be changed into small particles, so that the pressure of the gas phase medium is favorable for pressurizing the liquid phase medium, and the liquid phase medium can be better converted into the fog-like medium through the double-fluid nozzle 2.
Preferably, referring to fig. 3, the impact portion 204 is planar or concave. The planar striking portion 204 has a simple structure, facilitates the processing of the two-fluid nozzle 2, and contributes to reducing the manufacturing cost of the two-fluid nozzle 2 and thus the gasifier. The concave impact part 204 can enable the liquid phase medium to flow in a direction change of more than 90 degrees, so that the liquid phase medium and the gas phase medium are mixed with each other for more time when the liquid phase medium tends to change small particles, and the liquid phase medium is pressurized by the gas pressure of the gas phase medium better.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structural changes made by the contents of the specification and the drawings, or the direct or indirect application in other related technical fields, are included in the same way in the protection scope of the present invention.
