DETAILED DESCRIPTION

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings: Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] As the problem raised in the background technology, condensation heat exchange, as a basic phase change heat exchange process, mostly occurs in large-scale industrial production. The recovery of condensed water also helps the secondary utilization of water resources. Therefore, enhanced condensation technology can effectively achieve energy saving and consumption reduction from multiple angles. However, existing heat exchange equipment does have problems such as low heat exchange efficiency in actual application.

[0030] To solve the above problems, see Figure 1 The first aspect of the present invention discloses a structural diagram of an acoustic-based enhanced condensation system, including a circulating water pump 1, a heat exchanger 2, a condensation water pool 3, a speaker 4, a circulating water tank 5, a cold fluid pipeline 6 and a hot fluid pipeline 7.

[0031] The hot fluid heat exchange section 9 is arranged in the cold fluid heat exchange section 8, and the axes of the hot fluid heat exchange section 9 and the cold fluid heat exchange section 8 are parallel; a hot fluid is input into the input end of the hot fluid heat exchange section 9, and the hot fluid is in a gaseous state; a cold fluid is input into the cold fluid heat exchange section 8, and the cold fluid is water; a speaker 4 is arranged at the inlet end of the hot fluid heat exchange section 9, and the sound wave output direction of the speaker 4 is parallel to the flow direction of the hot fluid in the hot fluid heat exchange section 9; the speaker 4 outputs audible sound.

[0032] The speaker at the inlet end of the hot fluid heat exchange section in the above structure realizes the establishment of a sound field, so that the sound waves enter the heat exchange pipe in a directionally directed manner. The sound wave output direction of the speaker is the same as the flow direction of the hot fluid in the hot fluid heat exchange section. Gaseous hot fluid flows in the hot fluid heat exchange section, and the speaker can output audible sound. The audible sound can interfere with the gaseous hot fluid, thereby enhancing the convective heat transfer effect of the hot fluid in the hot fluid heat exchange section.

[0033] The thermal fluid of the present invention is in gaseous state, preferably high-pressure steam and saturated wet air.

[0034] It should be understood that the hot fluid heat exchange section 9 is a part of the hot fluid pipeline 7, and the cold fluid heat exchange section 8 is a part of the cold fluid pipeline 6. The diameter of the hot fluid heat exchange section 9 is smaller than the diameter of the cold fluid heat exchange section 8, so that the hot fluid heat exchange section 9 is arranged in the cold fluid heat exchange section 8, and the axis of the hot fluid heat exchange section 9 and the axis of the cold fluid heat exchange section 8 are parallel to each other, but the cold fluid and the hot fluid flow in opposite directions, so that the two types of fluids can exchange heat with each other during the mutual flow process.

[0035] In some embodiments of the present invention, a circulating water pump 1, a circulating water tank 5, a cooler 10 and a cold fluid heat exchange section 8 are sequentially arranged on the cold fluid pipeline 6 along the circulation direction of the cold fluid.

[0036] Specifically, the circulating water pump 1 is disposed on the cold fluid pipeline 6 to apply pressure to the cold fluid in the cold fluid pipeline 6 , and a portion of the cold fluid pipeline 6 is a cold fluid heat exchange section 8 .

[0037] Specifically, the circulating water tank 5 is the part that provides the cold fluid for the entire condensation system. The cold fluid pipeline 6 passes through the circulating water tank 5 twice. The circulating water tank 5 is provided with a first fluid outlet and a second fluid outlet. A cooler 10 is provided on the pipeline between the two fluid outlets. The cold fluid output from the circulating water tank 5 for the first time is cooled by the cooler 10 and then returns to the circulating water tank 5 again, thereby reducing the temperature of the cold fluid in the circulating water tank 5.

[0038] Furthermore, an opening is provided at the upper portion of the circulating water tank 5 , through which cold fluid can be added to ensure the content of cold fluid in the circulating water tank 5 .

[0039] The above structure allows the cold fluid to enter the outer pipe of the heat exchanger 2 under the pressure applied by the circulating water pump 1, and the hot fluid to enter the inner pipe of the heat exchanger 1. The condensed water is collected by the condensed water pool 3, and the sound field is established through the speaker 4. The circulating water after heat exchange returns to the circulating water pool 5 and is cooled again before recycling.

[0040] In some embodiments of the present invention, along the circulation direction of the hot fluid, the input end of the hot fluid pipeline 7 is connected to the hot fluid generating device to be cooled, such as the exhaust steam of the steam turbine in the thermal power unit, and a hot fluid heat exchange section 9 is provided on the hot fluid pipeline 7. In addition to inputting the hot fluid, the input end of the hot fluid heat exchange section 9 also extends a part into which a speaker 4 is inserted. The output end of the hot fluid pipeline 7 leads to the condensation water pool 3, and the cooled hot fluid flows into the condensation water pool 3.

[0041] In some embodiments of the present invention, the output end of the speaker 4 is inserted into the interior of the thermal fluid heat exchange section 9, so that the audible sound output from the speaker can be fully transmitted into the thermal fluid heat exchange section, ensuring the sound transmission effect.

[0042] In some embodiments of the present invention, the hot fluid heat exchange section 6 and the cold fluid heat exchange section 8 are arranged in a horizontal direction. Verification has found that the arrangement relative to the vertical direction or other directions can prevent the sound waves and the fluid from being affected by gravity or other acoustic buoyancy, thereby ensuring the disturbance effect.

[0043] In some embodiments of the present invention, the hot fluid heat exchange section 6 and the cold fluid heat exchange section 8 are coaxial, so that the heat exchange between the hot fluid and the cold fluid can be carried out uniformly, and the fluid in the hot fluid heat exchange section 6, whether in the upper layer or the lower layer, can exchange heat uniformly with the external cold fluid.

[0044] Furthermore, the heat exchange section 6 of the hot fluid is coaxial with the speaker 4, so that the sound waves output by the speaker can evenly strengthen every part in the heat exchange section of the hot fluid.

[0045] More preferably, the hot fluid heat exchange section 6, the speaker 4 and the cold fluid heat exchange section 8 are coaxial.

[0046] The second aspect of the present invention discloses an enhanced condensation method based on the acoustic enhanced condensation system of the above-mentioned system, wherein the speaker 4 outputs audible sound, and the audible sound disturbs the flow state of the gaseous hot fluid in the hot fluid heat exchange section 9, thinning the fluid boundary layer; the audible sound wave parameters are determined by the pipe diameter and the enhancement efficiency of the hot fluid heat exchange section 9.

[0047] The specific enhancement efficiency calculation formula is obtained through the following steps and formula calculations, where the cold and hot fluids are taken as water and wet saturated air, respectively, and the verification calculation can be carried out through the following method.

[0048] 1) Heat exchange power The latent heat of vaporization of the water involved in condensation express

[0049] Sensible heat of water involved in condensation express

[0050] Sensible heat of uncondensed water express

[0051] Sensible heat change of dry air express

[0052] Total heat transfer power express

[0053] in, is the latent heat of vaporization of water, , are the inlet and outlet moisture contents of the thermal fluid, is the specific heat capacity of condensed water at constant pressure, is the specific heat capacity of dry air at constant pressure, is the specific heat of water vapor at constant pressure, is the density of the thermal fluid. After the initial temperature of the fluid is measured, the above parameters can be obtained by looking up a table, calculating, etc. is the volume flow rate of the thermal fluid, , They are the inlet and outlet temperatures of the hot fluid, respectively, and can be measured by a flow meter and a temperature sensor.

[0054] 2) Heat transfer coefficient is the overall heat transfer coefficient

[0055] in Logarithmic mean temperature difference

[0056] is the convective heat transfer coefficient

[0057] is the heat exchange area, is the outer diameter of the heat exchange section 9 of the hot fluid, is the inner diameter of the heat fluid heat exchange section 9 tube, is the thermal conductivity of the tube wall in the heat exchange section 9 of the hot fluid.

[0058] 3) Enhance efficiency Using the convection heat transfer coefficient Defining reinforcement efficiency Indicates the ability of acoustic field to enhance heat transfer. From a numerical point of view, the enhancement efficiency is the ratio of the increase in the convective heat transfer coefficient under the action of the acoustic field to the convective heat transfer coefficient under the initial conditions. When it is positive, the sound field can enhance heat transfer.

[0059]

[0060] in, is the convective heat transfer coefficient of the heat exchanger under the action of the acoustic field, is the convective heat transfer coefficient of the heat exchanger in the silent field.

[0061] During the on-site adjustment and experiment process, the output parameters of the speaker are related to the parameters of the pipeline itself and the cold and hot fluids. Through the calculation of the above parameters, the output parameters of the speaker and the cold and hot fluids meet the heat exchange requirements.

[0062] Experimental results Through laboratory tests and calculations of heat transfer power, heat transfer coefficient and enhancement efficiency, the effect of the sound field on the condensation effect of the heat exchanger can be intuitively demonstrated. When the sound waves of a specific frequency reach a certain sound pressure level, the heat transfer power and heat transfer coefficient of the heat exchanger will show a significant increase trend, and the enhancement efficiency is greater than zero, indicating that the sound field plays a significant positive role in condensation heat transfer. The results verify that the audible sound of a specific frequency can enhance the condensation effect in the heat exchanger when it reaches a certain sound pressure level, and the enhancement efficiency is high. Through the analysis of the technical mechanism, it is essentially because the sound waves cause the pipes and the medium to vibrate, disturbing the boundary layer of the flow field, thereby affecting the heat exchange. At the same time, the small droplets in the condensation process will aggregate under the action of the sound field, increasing the amount of condensed water recovered.
