Description

Technical Field

[0001] The invention belongs to the technical field of industrial production, and in particular relates to a steam condensation recovery device. Background Art

[0002] Steam, a common heat energy carrier, is widely used in industrial production processes, including heating, drying, and distillation. However, after use, steam is often released into the atmosphere as waste gas, which not only wastes energy but also has potential negative environmental impacts. Therefore, effectively recovering and utilizing the heat energy contained in this waste steam has become a key research topic in the field of industrial energy conservation and emission reduction.

[0003] Steam condensation recovery technology is a key component in achieving steam heat recovery and utilization. Traditional steam condensation units typically employ a simple condenser tube structure, achieving condensation through direct contact between the cooling medium and steam. However, this structure has numerous drawbacks in practical applications, including low condensation efficiency, uneven heat exchange, and a large equipment footprint. In particular, traditional condensation units often struggle to adapt to changes in steam flow or temperature, resulting in unstable condensation results and even failure to meet production requirements.

[0004] Furthermore, with the continuous development of industrial automation and intelligent technologies, intelligent control of the steam condensation recovery process has become a key research topic. By introducing intelligent components such as sensors and actuators, real-time monitoring and adjustment of parameters such as the flow rate and temperature of steam and cooling media can ensure that the condensing unit maintains efficient condensation performance under various operating conditions.

[0005] In order to solve the above problems, a steam condensation recovery device is proposed, which solves the problems of low condensation efficiency, uneven heat exchange and large equipment footprint of the current condensation device. Summary of the Invention

[0006] The purpose of the present invention is to provide a steam condensation recovery device to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a steam condensation recovery device, comprising a condenser tube, the condenser tube being spiral-shaped and made of glass, with an inlet and an outlet fixed at both ends, the inlet being located below the condenser tube, and the outlet being located above; The inner diameter of the condenser tube is fixed with a guide rib, which is spiral and triangular in cross section, with a density of sparse at the top and dense at the bottom, and the number of circles decreases near the outlet; The lower end surface of the guide rib is provided with a blade groove 1, and the blade 1 is hinged in the blade groove 1 through two telescopic rods, and the telescopic rods are respectively located at both ends of the guide rib cross section; The outer diameter of the condenser tube is evenly distributed with several honeycomb panels, and a condensation cavity is formed between adjacent honeycomb panels. The first honeycomb panel close to the outlet is provided with a medium inlet, and the other honeycomb panels are provided with medium through holes, and the last honeycomb panel is closed with the medium. The motor is fixed on the inner wall of the inlet, and the outer diameter of the motor seat is provided with a second blade. The end surface of the second blade is provided with a second blade groove, and the groove is connected to the third blade via a hinged rod and an air bag. The air port is connected to the condensation chamber through the pump body. The inner wall of the inlet is provided with a plurality of nozzles in a circumferential array, the nozzle input ends are communicated with the condensation chamber, and the output ends are tangent to the inner diameter of the inlet.

[0008] The present invention further states that the blade inclination angle α of the guide rib satisfies: , where v 蒸汽 : The speed of steam entering the condensation chamber; v 冷却介质 : The ejection velocity of the cooling medium.

[0009] The present invention further states that the adjustment formula for the blade three tilt angle β of the blade two is: , Where: k: temperature response coefficient of steam; :Steam temperature, : Steam temperature under design conditions.

[0010] The present invention further illustrates that the steps of the angle calculation formula of the blade 1 are as follows: During the steam condensation process, when the steam and the cooling medium come into contact in the condensation chamber, a shear layer is formed between the two fluids. The angle θ of the shear layer is determined by the ratio of the speed of the steam entering the condensation chamber to the speed of the cooling medium ejected from the nozzle, and satisfies: , The function of the guide rib is to guide the steam to form a stable spiral flow. The angle between the blade and the horizontal plane is α, and its 2α should be slightly smaller than the shear layer angle θ to avoid fluid separation and excessive turbulence. Considering the fluid viscosity, surface roughness and the geometric shape of the guide edge, the The correction term is used to ensure that the steam streamline forms a stable attached flow with the guide rib surface and the cooling medium forms a uniform liquid film along the guide rib surface; get: .

[0011] The present invention further illustrates that the blade adjustment method is: when When: At this time, the steam streamlines and the guide rib surface can form a stable attached flow, and the cooling medium can form a uniform liquid film along the guide rib surface.

[0012] The present invention further illustrates that the blade adjustment method is: when When: At this time, the steam streamline cannot closely adhere to the surface of the guide edge, resulting in flow separation. The separated steam may form vortices or backflows, increasing local turbulence and destroying the continuity of the overall spiral flow; At the same time, if α is too large, the cooling medium will directly impact the core area of ​​the steam flow instead of forming a uniform liquid film along the surface of the guide edge. This impact will weaken the heat exchange efficiency between steam and cooling medium and may cause splashing or atomization of cooling medium, thus affecting the condensation effect. At this time, by starting the telescopic rod near the center of the condenser tube, the telescopic rod near the center of the condenser tube extends to drive the blade 1 to rotate, thereby reducing the inclination angle of the blade 1 until the desired angle is reached.

At this time, by starting the telescopic rod near the center of the condenser tube, the telescopic rod near the center of the condenser tube extends to drive the blade 1 to rotate, thereby reducing the inclination angle of the blade 1 until the desired angle is reached.

[0014] The present invention further describes the steps for adjusting the inclination angle of blade three: During the steam condensation process, blade 2 enhances the heat exchange between steam and cooling medium through forced convection, where the angle β of blade 2 directly affects the swirl intensity. in: , Where: v θ : The component of the steam velocity in the tangential direction perpendicular to the main axis of fluid flow; v 轴向 : the component of steam velocity in the direction of the main axis of fluid flow; When the steam temperature T changes, its density and viscosity change accordingly, and β needs to be adjusted to maintain the optimal swirl intensity. When the steam temperature T increases, the steam density decreases, and β needs to be increased to maintain the same swirl intensity. Adjusted angle of blade 2 , Before condensing, the pump is started to change the impact angle between the steam and the blade 3 so that the angle between the blade 3 and the horizontal plane is β; When the steam enters the inlet, the temperature T of the steam is measured to calculate the value of the tilt angle of the blade 2 that needs to be adjusted. .

[0015] The present invention further illustrates that the three blade adjustment methods are: when When the blades act on the steam in a tangential direction, the tangential force of the steam increases, resulting in the tangential velocity component v of the steam. θ Significantly increase the high tangential velocity component to generate stronger centrifugal force, so that the steam fits more closely to the wall of the condensation chamber, forming a thinner condensate film; This causes the axial flow of steam between the blades to be obstructed, and the axial velocity component v 轴向 The decrease in the axial velocity component may cause flow separation or vortex, resulting in uneven distribution of steam in the condensation chamber, thus affecting the condensation effect; At this time, by starting the pump body, the impact angle between the steam and blade three is reduced.

[0016] The present invention further illustrates that the three blade adjustment methods are: when When the blades act on the steam in a tangential direction, the tangential force of the steam is reduced, resulting in the tangential velocity component v of the steam. θ Significantly reduced, the centrifugal force generated by the low tangential velocity component is small, the steam cannot fully adhere to the wall of the condensation chamber, forming a thicker condensate film, reducing the heat exchange efficiency; This results in a decrease in the axial flow resistance of steam between the blades, and the axial velocity component v 轴向 As the pressure increases, the steam tends to flow along the axis, and the spiral flow characteristics are weakened, resulting in uneven flow distribution, which affects the condensation effect. At this time, by starting the pump body, the impact angle between the steam and blade three is increased.

[0017] Compared with the prior art, the present invention has the following beneficial effects: the present invention increases the residence time of steam in the condenser through the spiral condenser design, thereby improving the condensation efficiency. The guide ribs in the condenser tube guide the steam to form a stable spiral flow, further enhancing the contact area and heat exchange efficiency between the steam and the condensing medium; By adjusting the angle between blade 1 and the horizontal plane through the telescopic rod, the impact angle between steam and blade can be flexibly changed, thereby optimizing the steam flow path and condensation effect, making the device adaptable to the steam condensation requirements under different working conditions, and improving the versatility and flexibility of the device; By precisely controlling the inclination angle of blade 1, the steam streamline forms a stable attached flow with the guide rib surface. At the same time, the cooling medium forms a uniform liquid film along the guide rib surface. This uniform liquid film helps improve heat exchange efficiency and reduce local overheating and uneven condensation problems. The design of blade two enhances the heat exchange between steam and cooling medium through forced convection, thereby improving condensation efficiency. The angle of blade two can be dynamically adjusted according to the steam temperature to maintain the optimal swirl intensity and further optimize the heat exchange effect.

[0021] Several honeycomb panels 2 are mounted on the outer diameter of the condenser tube 1, forming a condensation cavity 201 between adjacent honeycomb panels 2 for storing the medium. The honeycomb panels 2 are evenly distributed and fixed to the outer diameter of the condenser tube 1. Baffles 3 are fixed to the sidewalls of the honeycomb panels 2 to prevent the outflow of water vapor.

[0022] It should be noted that: the first honeycomb panel 2 close to the outlet 102 is the first honeycomb panel 2, the first honeycomb panel 2 close to the inlet 101 is the last honeycomb panel 2, and the remaining honeycomb panels 2 are located between the first honeycomb panel 2 and the last honeycomb panel 2; The first honeycomb panel 2 is fixed with a medium inlet 4, and the remaining honeycomb panels 2 are provided with medium through holes 401 for circulating the medium. The medium through holes 401 are communicated with the medium inlet 4, and the last honeycomb panel 2 is used to prevent medium leakage.

[0023] like Figure 4 、 Figure 6 and Figure 7As shown, in some embodiments, a motor 5 is fixed in the inlet 101 through a bracket, a motor base 501 is fixed to the output end of the motor 5, a blade 2 6 is fixed on the outer diameter of the motor base 501, a blade 2 groove 601 is provided on the end surface of the blade 2 6, a blade 3 602 is rotatably connected in the blade 2 groove 601 through a hinge rod 6011, an air bag 603 is fixed between the blade 3 602 and the blade 2 groove 601, an air port 604 is provided on the side wall of the blade 2 groove 601, and the air port 604 is communicated with the inflation port of the air bag 603. A pump body 605 is fixed on the outer diameter of the motor base 501 , the output end of the pump body 605 is communicated with the air port 604 , and the fixed end of the pump body 605 is communicated with the condensation chamber 201 through a pipeline.

[0024] A plurality of nozzles 606 are fixed on the inner wall of the inlet 101 . The nozzles 606 are arranged in a circular array around the center of the inlet 101 . The input ends of the nozzles 606 are connected to the condensation chamber 201 , and the output ends of the nozzles 606 are tangent to the inner diameter of the inlet 101 .

[0025] Example 1: When steam condensation is required, the condensing medium enters the condensing chamber 201 from the medium inlet 4, and the steam enters the condensing tube 1 from the inlet 101. The steam in the condensing tube 1 is condensed and liquefied into liquid, thereby completing the condensation of the steam.

[0026] During the condensation of steam, the steam rises along the spiral direction of the condenser tube 1 . During the rising process of the steam in the condenser tube 1 , the steam collides with the surface of the blade 105 and is guided along the direction of the guide rib 103 .

[0027] By activating the two telescopic rods 106 , the angle between the blade 105 and the horizontal plane is changed, thereby changing the impact angle between the steam and the blade 105 .

[0028] By starting the nozzle 606 , the condensing medium in the condensing chamber 201 is ejected from the nozzle 606 in a direction along the tangent direction of the inner diameter of the inlet 101 . The ejection speed of the nozzle 606 is changed by changing the output power of the nozzle 606 .

[0029] By starting the pump body 605, the condensing medium in the condensing chamber 201 is input into the interior of the airbag 603. The condensing medium inside the airbag 603 expands the airbag 603, which drives the blade three 602 to rotate, thereby changing the impact angle between the steam and the blade three 602.

[0030] Example 2: During the steam condensation process, when the steam and the cooling medium come into contact in the condenser tube 1, the two fluids form a shear layer. The angle θ of the shear layer is determined by the ratio of the speed of the steam entering the condenser tube 1 to the speed of the cooling medium ejected from the nozzle 606, and satisfies: , Where: v 蒸汽 : The speed of steam entering the condenser 1; v 冷却介质 : The ejection velocity of the cooling medium.

[0031] The function of the guide rib 103 is to guide the steam to form a stable spiral flow. The angle between the blade 105 and the horizontal plane is α, and its 2α should be slightly smaller than the shear layer angle θ to avoid fluid separation and excessive turbulence.

[0032] Considering the fluid viscosity, surface roughness and the geometric shape of the guide edge 103, the The correction term is used to ensure that the steam streamline forms a stable attached flow with the surface of the guide rib 103 and the cooling medium forms a uniform liquid film along the surface of the guide rib 103.

[0033] We can get: , when When: At this time, the steam streamlines and the surface of the guide rib 103 can form a stable attached flow, and the cooling medium can form a uniform liquid film along the surface of the guide rib 103.

[0034] when When: At this time, the steam streamline cannot closely adhere to the surface of the guide rib 103, resulting in flow separation. The separated steam may form a vortex or backflow, increasing the local turbulence and destroying the continuity of the overall spiral flow.

[0035] At the same time, if α is too large, the cooling medium will directly impact the core area of ​​the steam flow instead of forming a uniform liquid film along the surface of the guide edge 103. This impact will weaken the heat exchange efficiency between steam and cooling medium and may cause splashing or atomization of cooling medium, thereby affecting the condensation effect.

[0036] At this time, by starting the telescopic rod 106 near the center of the condenser 1, the telescopic rod 106 near the center of the condenser 1 extends to drive the blade 105 to rotate, thereby reducing the inclination angle of the blade 105 until the desired angle is reached.

[0037] when When: The steam cannot form sufficient spiral flow. The centrifugal force of the spiral flow is weakened, and the steam streamlines are too close to the axis of the condenser tube 1, resulting in insufficient mixing of the steam and the cooling medium.

[0038] The liquid film formed by the cooling medium along the surface of the guide rib 103 may be too thin to effectively cover the entire heat exchange surface. In addition, the tangential injection of the cooling medium may not fully penetrate into the steam core area due to the high steam flow rate, thereby affecting the condensation effect.

[0039] At this time, by starting the telescopic rod 106 close to the outer wall of the condenser tube 1, the telescopic rod 106 close to the outer wall of the condenser tube 1 extends to drive the blade 105 to rotate, thereby increasing the inclination angle of the blade 105 until the desired angle is reached.

[0040] Example 3: During the steam condensation process, the blade 2 6 enhances the heat exchange between the steam and the cooling medium through forced convection, wherein the angle β of the blade 2 6 directly affects the swirl intensity.

[0041] in: , Where: v θ : The component of the vapor velocity in the tangential direction perpendicular to the main axis of fluid flow (the axis of the condenser tube); v 轴向 : The component of the vapor velocity in the direction of the main axis of fluid flow (the axis of the condenser tube).

[0042] When the steam temperature T changes, its density and viscosity change accordingly. β needs to be adjusted to maintain the optimal swirl intensity. When the steam temperature T increases, the steam density decreases. β needs to be increased to maintain the same swirl intensity.

[0043] Adjusted blade angle , Where: k: temperature response coefficient of steam; : Steam temperature under design conditions.

[0044] Before the condensation operation is performed, the pump body 605 is started to change the impact angle between the steam and the blade three 602 so that the angle between the blade three 602 and the horizontal plane is β.

[0045] When the steam enters the inlet 101, the temperature T of the steam is measured, and the value of the tilt angle of the blade 2 6 that needs to be adjusted is calculated. ; when When the blade 3 602 exerts a tangential force on the steam, the tangential velocity component v of the steam increases. θ Significantly increasing the high tangential velocity component generates a stronger centrifugal force, causing the steam to adhere more closely to the wall of the condenser tube 1, forming a thinner condensate film.

[0046] This causes the axial flow of steam between the blades to be obstructed, and the axial velocity component v 轴向The decrease in the axial velocity component may cause flow separation or vortex, resulting in uneven distribution of steam in the condenser tube 1, thereby affecting the condensation effect.

[0047] At this time, by starting the pump body 605, the impact angle between the steam and the blade three 602 is reduced.

[0048] when When the blade 3 602 exerts a tangential force on the steam, the tangential velocity component v of the steam decreases. θ The centrifugal force generated by the low tangential velocity component is significantly reduced, and the steam cannot fully adhere to the wall of the condenser tube 1, forming a thicker condensate film, which reduces the heat exchange efficiency.

[0049] This results in a decrease in the axial flow resistance of steam between the blades, and the axial velocity component v 轴向 As the pressure increases, the steam tends to flow along the axis, and the spiral flow characteristics are weakened, resulting in uneven flow distribution, which affects the condensation effect.

[0050] At this time, by starting the pump body 605, the impact angle between the steam and the blade three 602 is increased.

The steam condensation recovery device according to claim 8, characterized in that: The adjustment method of the blade three (602) is: when When the blade 3 (602) exerts a stronger tangential force on the steam, the tangential velocity component v of the steam increases. θ Significantly increase the high tangential velocity component to generate stronger centrifugal force, so that the steam adheres more closely to the condenser tube wall, forming a thinner condensate film; This causes the axial flow of steam between the blades to be obstructed, and the axial velocity component v 轴向 The decrease in the axial velocity component may induce flow separation or vortex, resulting in uneven distribution of steam in the condenser tube (1), thereby affecting the condensation effect; At this time, by starting the pump body (605), the impact angle between the steam and the blade three (602) is reduced.

10. The steam condensation recovery device according to claim 9, characterized in that: The adjustment method of the blade three (602) is: when When the blade 3 (602) exerts a tangential force on the steam, the tangential velocity component v of the steam decreases. θ Significantly reduced, the centrifugal force generated by the low tangential velocity component is small, the steam cannot fully adhere to the wall of the condenser tube (1), forming a thicker condensate film, reducing the heat exchange efficiency; This results in a decrease in the axial flow resistance of steam between the blades, and the axial velocity component v 轴向 As the pressure increases, the steam tends to flow along the axis, and the spiral flow characteristics are weakened, resulting in uneven flow distribution, which affects the condensation effect. At this time, by starting the pump body (605), the impact angle between the steam and the blade three (602) is increased.
