Description

Technical Field

[0001] This invention belongs to the field of industrial production technology, and specifically relates to a steam condensation and recovery device. Background Technology

[0002] In industrial production, steam, as a commonly used heat energy carrier, is widely used in various processes such as heating, drying, and distillation. However, after use, steam is often released into the atmosphere as waste gas, which not only wastes energy but may also have negative environmental impacts. Therefore, how to effectively recover and utilize the heat energy in this waste steam has become an important research direction in the field of industrial energy conservation and emission reduction.

[0003] Steam condensation recovery technology is a key step in realizing the recovery and utilization of steam heat energy. Traditional steam condensation devices typically employ a simple condenser tube structure, achieving condensation through direct contact between the cooling medium and steam. However, this structure has many shortcomings in practical applications, such as low condensation efficiency, uneven heat exchange, and large equipment footprint. In particular, traditional condensation devices often struggle to adapt to changes in steam flow rate or temperature, leading to unstable condensation effects and even failing to meet production requirements.

[0004] Furthermore, with the continuous development of industrial automation and intelligent technologies, how to achieve intelligent control of the steam condensation and recovery process has become an important research direction. By introducing intelligent components such as sensors and actuators, and monitoring and adjusting parameters such as the flow rate and temperature of steam and cooling medium in real time, it is possible to ensure that the condensation unit maintains high-efficiency condensation performance under different operating conditions.

[0005] To address the aforementioned issues, a steam condensation recovery device is proposed, which solves the problems of low condensation efficiency, uneven heat exchange, and large equipment footprint of current condensation devices. Summary of the Invention

[0006] The purpose of this invention is to provide a steam condensation and recovery device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a steam condensation recovery device, including a condenser tube, the condenser tube being spiral-shaped and made of glass, with an inlet and an outlet fixed at both ends respectively, the inlet being located below the condenser tube and the outlet being located above it;

[0008] The inner diameter of the condenser tube is fixed with a flow guide rib. The flow guide rib is spiral and has a triangular cross-section. Its winding density is sparse at the top and dense at the bottom, and the number of windings decreases near the outlet.

[0009] The lower end face of the guide rib is provided with a blade groove, and a blade is hinged in the blade groove by two telescopic rods. The telescopic rods are located at both ends of the cross section of the guide rib.

[0010] The outer diameter of the condenser tube is uniformly distributed with several honeycomb plates, and a condensation cavity is formed between adjacent honeycomb plates. The first honeycomb plate near the outlet is provided with a medium inlet, the remaining honeycomb plates are provided with medium through holes, and the last honeycomb plate is closed for the medium.

[0011] A motor is fixed to the inner wall of the inlet. Blade 2 is installed on the outer diameter of the motor base. Blade 2 has a blade groove on its end face. Blade 3 is connected to the groove through a hinge rod and an air bag. The air port is connected to the condensation chamber through the pump body.

[0012] The inlet inner wall has a circumferential array of several nozzles, with the nozzle input end connected to the condensation chamber and the output end tangent to the inlet inner diameter.

[0013] The present invention further illustrates that the blade tilt angle α of the guide ridge satisfies:

[0014] ,

[0015] Where v 蒸汽 : The velocity of steam entering the condenser; v 冷却介质 : The ejection speed of the cooling medium.

[0016] The present invention further explains that the formula for adjusting the tilt angle β of blade two is as follows:

[0017] ,

[0018] Where: k: temperature response coefficient of steam; The temperature of the steam, Steam temperature under design conditions.

[0019] The present invention further explains that the angle calculation formula for the first blade is as follows:

[0020] During steam condensation, when steam and cooling medium come into contact in the condensation chamber, a shear layer is formed between the two fluids. The angle θ between the shear layers is determined by the ratio of the velocity of steam entering the condensation chamber to the velocity of the cooling medium exiting the nozzle, and satisfies the following:

[0021] ,

[0022] The function of the guide ridge is to guide the steam to form a stable helical 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.

[0023] Considering fluid viscosity, surface roughness, and the geometry of the guide ridges, we introduce... The correction is to ensure that the steam streamline forms a stable adhering flow with the surface of the guide ridge, and that the cooling medium forms a uniform liquid film along the surface of the guide ridge.

[0024] get: .

[0025] The present invention further explains that the blade adjustment method is as follows:

[0026] when At this time, the steam streamlines and the surface of the guide ridge can form a stable adhering flow, and the cooling medium can form a uniform liquid film along the surface of the guide ridge.

[0027] The present invention further explains that the blade adjustment method is as follows:

[0028] when At this time, the steam streamlines cannot closely adhere to the surface of the guide ridge, resulting in flow separation. The separated steam may form vortices or backflow, increasing local turbulence and disrupting the continuity of the overall spiral flow.

[0029] At the same time, an excessively large α will cause the cooling medium to directly impact the core area of ​​the steam flow instead of forming a uniform liquid film along the surface of the guide ridge. This impact will weaken the heat exchange efficiency between the steam and the cooling medium and may cause the cooling medium to splash or atomize, thus affecting the condensation effect.

[0030] At this time, by activating the telescopic rod near the center of the condenser tube, the telescopic rod extends and drives the blade to rotate, thereby reducing the tilt angle of the blade until the desired angle is reached.

[0031] The present invention further explains that the blade adjustment method is as follows:

[0032] when At this time, the steam streamlines cannot closely adhere to the surface of the guide ridge, resulting in flow separation. The separated steam may form vortices or backflow, increasing local turbulence and disrupting the continuity of the overall spiral flow.

[0033] At the same time, an excessively large α will cause the cooling medium to directly impact the core area of ​​the steam flow instead of forming a uniform liquid film along the surface of the guide ridge. This impact will weaken the heat exchange efficiency between the steam and the cooling medium and may cause the cooling medium to splash or atomize, thus affecting the condensation effect.

[0034] At this time, by activating the telescopic rod near the center of the condenser tube, the telescopic rod extends and drives the blade to rotate, thereby reducing the tilt angle of the blade until the desired angle is reached.

[0035] The present invention further describes the steps for adjusting the tilt angle of the third blade:

[0036] During the steam condensation process, blade two enhances the heat exchange between steam and the cooling medium through forced convection, where the angle β of blade two directly affects the swirl intensity.

[0037] in: ,

[0038] In the formula: v θ : The component of steam velocity in the tangential direction perpendicular to the principal axis of fluid flow;

[0039] v 轴向 : The component of steam velocity along the principal axis of fluid flow;

[0040] When the temperature T of steam changes, its density and viscosity change accordingly. β needs to be adjusted to maintain the optimal swirling intensity. When the steam temperature T increases, the steam density decreases, and β needs to be increased to maintain the same swirling intensity.

[0041] Adjusted blade angle ,

[0042] Before condensation, the pump body is started to change the impact angle between the steam and the third blade, so that the angle between the third blade and the horizontal plane is β.

[0043] When steam enters the inlet, the steam temperature T is measured to calculate the required adjustment angle of blade two. .

[0044] The present invention further explains that the blade three-adjustment method is as follows:

[0045] when At this time, the tangential forces acting on the steam from the three pairs of blades increase, leading to an increase in the tangential velocity component v of the steam. θ The significantly increased high tangential velocity component generates stronger centrifugal force, causing the steam to adhere more tightly to the condensation chamber wall and form 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 reduction in axial velocity component may trigger flow separation or vortices, leading to uneven distribution of steam in the condensation chamber and thus affecting the condensation effect.

[0047] At this point, by starting the pump body, the impact angle between the steam and the third blade is reduced.

[0048] The present invention further explains that the blade three-adjustment method is as follows:

[0049] when At this time, the tangential forces acting on the steam on the three pairs of blades decrease, resulting in a decrease in the tangential velocity component v of the steam. θThe centrifugal force generated by the low tangential velocity component is relatively small, and the steam cannot fully adhere to the condensation chamber wall to form a thicker condensate film, thus reducing the heat exchange efficiency.

[0050] This leads to a reduction in the axial flow resistance of steam between the blades, and an increase in the axial velocity component v. 轴向 As the volume increases, steam tends to flow more along the axial direction, weakening the spiral flow characteristics and resulting in uneven flow distribution, thus affecting the condensation effect.

[0051] At this point, by starting the pump body, the impact angle between the steam and the third blade is increased.

[0052] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention, through the spiral condenser tube design, increases the residence time of steam in the condenser tube, thereby improving the condensation efficiency.

[0053] The guide ridges inside the condenser tubes 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.

[0054] By adjusting the angle between the blade and the horizontal plane using the telescopic rod, the impact angle between the steam and the blade can be flexibly changed, thereby optimizing the steam flow path and condensation effect. This allows the device to adapt to the steam condensation requirements under different working conditions, improving the versatility and flexibility of the device.

[0055] By precisely controlling the tilt angle of blade one, a stable adhering flow is ensured between the steam streamline and the surface of the guide rib. At the same time, the cooling medium forms a uniform liquid film along the surface of the guide rib. This uniform liquid film helps to improve heat exchange efficiency and reduce problems such as local overheating and uneven condensation.

[0056] The design of the second blade enhances the heat exchange between steam and cooling medium through forced convection, thereby improving condensation efficiency. The angle of the second blade can be dynamically adjusted according to the steam temperature to maintain the optimal swirling intensity and further optimize the heat exchange effect.

Detailed Implementation

[0066] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0067] Please see Figure 1-7 The present invention provides a technical solution: a steam condensation recovery device, including a condenser tube 1;

[0068] like Figures 1-3 As shown, in some embodiments, the condenser tube 1 is spiral-shaped and made of glass. An inlet 101 and an outlet 102 are fixed at both ends of the condenser tube 1 for the entry and exit of water vapor. The inlet 101 is located below the condenser tube 1, and the outlet 102 is located above the condenser tube 1.

[0069] like Figure 4 and Figure 5As shown, in some embodiments, a guide rib 103 is fixed on the inner diameter of the condenser tube 1. The guide rib 103 is spiral in shape, with its two ends located at the two ends of the condenser tube 1. The cross-section of the guide rib 103 is triangular, and the guide rib 103 is sparse at the top and dense at the bottom, with fewer turns near the outlet 102. A blade groove 104 is formed on the lower end face of the guide rib 103. A blade 105 is rotatably connected in the blade groove 104. The blade 105 is parallel to the upper end face of the blade groove 104. Two telescopic rods 106 are provided between the blade 105 and the blade groove 104. The fixed ends of the two telescopic rods 106 are fixed to the blade groove 104, and the telescopic ends are hinged to the upper end face of the blade 105. The two telescopic rods 106 are located at the two ends of the cross-section of the guide rib 103.

[0070] A plurality of honeycomb plates 2 are installed on the outer diameter of the condenser tube 1, and a condensation cavity 201 is formed between adjacent honeycomb plates 2. The condensation cavity 201 is used to store the medium. The plurality of honeycomb plates 2 are evenly distributed and fixed to the outer diameter of the condenser tube 1. A baffle 3 is fixed to the side wall of each honeycomb plate 2 to prevent water vapor from flowing out.

[0071] It should be further explained that: the first honeycomb panel 2 near the outlet 102 is the first honeycomb panel 2, the first honeycomb panel 2 near 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.

[0072] The first honeycomb plate 2 is fixed with a medium inlet 4, and the remaining honeycomb plates 2 are provided with medium through holes 401 for the flow of medium. The medium through holes 401 are connected to the medium inlet 4. The last honeycomb plate 2 is used to prevent medium leakage.

[0073] like Figure 4 , Figure 6 and Figure 7 As shown, in some embodiments, a motor 5 is fixed inside the inlet 101 by a bracket. A motor base 501 is fixed to the output end of the motor 5. A second blade 6 is fixed to the outer diameter of the motor base 501. A second blade groove 601 is formed on the end face of the second blade 6. A third blade 602 is rotatably connected to the second blade groove 601 via a hinge rod 6011. An airbag 603 is fixed between the third blade 602 and the second blade groove 601. An air port 604 is formed on the side wall of the second blade groove 601, and the air port 604 communicates with the inflation port of the airbag 603.

[0074] A pump body 605 is fixed on the outer diameter of the motor base 501. The output end of the pump body 605 is connected to the air port 604, and the fixed end of the pump body 605 is connected to the condensation chamber 201 through a pipe.

[0075] A plurality of nozzles 606 are fixed on the inner wall of the inlet 101. The plurality of nozzles 606 are arranged in a circumferential array based on the center of the inlet 101. The input ends of the plurality of nozzles 606 are connected to the condensation chamber 201, and the output ends of the plurality of nozzles 606 are tangent to the inner diameter of the inlet 101.

[0076] Example 1: When steam needs to be condensed, the condensing medium enters the interior of the condensing chamber 201 from the medium inlet 4, and the steam enters the interior of 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.

[0077] During the steam condensation process, the steam rises along the spiral direction of the condenser tube 1. As the steam rises in the condenser tube 1, it impacts the surface of the blade 105 and is guided along the direction of the guide rib 103.

[0078] 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.

[0079] By activating the nozzle 606, the condensing medium in the condensing chamber 201 is ejected from the nozzle 606 in the direction of the ejection along the tangent 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.

[0080] By activating the pump body 605, the condensing medium in the condensing chamber 201 is introduced into the air bag 603. The condensing medium inside the air bag 603 expands the air bag 603, causing the blade 602 to rotate, thereby changing the impact angle between the steam and the blade 602.

[0081] Example 2: During steam condensation, when steam and cooling medium come into contact inside condenser tube 1, a shear layer is formed between the two fluids. The angle θ between the shear layers is determined by the ratio of the velocity of steam entering condenser tube 1 to the velocity of cooling medium ejected from nozzle 606, and satisfies the following:

[0082] ,

[0083] In the formula: v 蒸汽 : The speed at which steam enters condenser tube 1;

[0084] v 冷却介质 : The ejection speed of the cooling medium.

[0085] 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.

[0086] Considering fluid viscosity, surface roughness, and the geometry of the guide rib 103, we introduce... The correction is to ensure that the steam flow lines form a stable adhering flow on the surface of the guide rib 103 and that the cooling medium forms a uniform liquid film along the surface of the guide rib 103.

[0087] We can obtain: ,

[0088] when At this time, the steam streamline and the surface of the guide rib 103 can form a stable adhering flow, and the cooling medium can form a uniform liquid film along the surface of the guide rib 103.

[0089] 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 vortices or backflow, increasing local turbulence and disrupting the continuity of the overall spiral flow.

[0090] At the same time, an excessively large α will cause the cooling medium to directly impact the core area of ​​the steam flow instead of forming a uniform liquid film along the surface of the guide rib 103. This impact will weaken the heat exchange efficiency between the steam and the cooling medium and may cause splashing or atomization of the cooling medium, thereby affecting the condensation effect.

[0091] At this time, by activating the telescopic rod 106 near the center of the condenser tube 1, the telescopic rod 106 near the center of the condenser tube 1 extends and drives the blade 105 to rotate, thereby reducing the tilt angle of the blade 105 until the required angle is reached.

[0092] when At this point, the steam cannot form a sufficient spiral flow. The centrifugal force of the spiral flow weakens, and the steam streamline will be too close to the axis of condenser tube 1, resulting in insufficient mixing of steam and cooling medium.

[0093] 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 be able to fully penetrate into the steam core area due to the excessively high steam velocity, thus affecting the condensation effect.

[0094] At this time, by activating the telescopic rod 106 near the outer wall of the condenser tube 1, the telescopic rod 106 near the outer wall of the condenser tube 1 extends and drives the blade 105 to rotate, thereby increasing the tilt angle of the blade 105 until the required angle is reached.

[0095] Example 3: During the steam condensation process, blade 26 enhances the heat exchange between steam and cooling medium through forced convection, wherein the angle β of blade 26 directly affects the swirl intensity.

[0096] in: ,

[0097] In the formula: v θ The component of the steam velocity in the tangential direction perpendicular to the main axis of fluid flow (the axis of the condenser tube);

[0098] v 轴向 The component of the steam velocity along the main axis of fluid flow (the axis of the condenser).

[0099] When the temperature T of steam changes, its density and viscosity also change. β needs to be adjusted to maintain the optimal swirling intensity. When the steam temperature T increases, the steam density decreases, and β needs to be increased to maintain the same swirling intensity.

[0100] The angle of the adjusted blade 2.6 ,

[0101] Where: k: temperature response coefficient of steam;

[0102] Steam temperature under design conditions.

[0103] Before condensation, the impact angle between the steam and the blade 602 is changed by starting the pump body 605, so that the angle between the blade 602 and the horizontal plane is β.

[0104] When steam enters inlet 101, the steam temperature T is measured to calculate the required tilt angle of blade 26. ;

[0105] when At that time, the tangential force exerted by the blade 602 on the steam increases, leading to an increase in the tangential velocity component v of the steam. θ The significantly increased high tangential velocity component generates stronger centrifugal force, causing the steam to adhere more tightly to the wall of condenser tube 1, forming a thinner condensate film.

[0106] This causes the axial flow of steam between the blades to be obstructed, and the axial velocity component v 轴向 The reduction in axial velocity component may trigger flow separation or vortices, resulting in uneven distribution of steam within condenser tube 1, thus affecting the condensation effect.

[0107] At this time, by starting the pump body 605, the impact angle between the steam and the blade 602 is reduced.

[0108] when At that time, the tangential force exerted by the blade 602 on the steam decreases, resulting in a decrease in the tangential velocity component v of the steam. θ The centrifugal force generated by the low tangential velocity component is significantly reduced, and the steam cannot fully adhere to the wall of condenser tube 1 to form a thicker condensate film, thus reducing the heat exchange efficiency.

[0109] This leads to a reduction in the axial flow resistance of steam between the blades, and an increase in the axial velocity component v. 轴向 As the volume increases, steam tends to flow more along the axial direction, weakening the spiral flow characteristics and resulting in uneven flow distribution, thus affecting the condensation effect.

[0110] At this time, by starting the pump body 605, the impact angle between the steam and the blade 602 is increased.

[0112] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features, and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

A steam condensation recovery device according to claim 4, characterized in that: The adjustment method for the first blade (105) is as follows: when At this time, the steam cannot form a sufficient spiral flow, the centrifugal force of the spiral flow is weakened, and the steam streamline will be too close to the axis of the condenser tube (1), resulting in insufficient mixing of steam and cooling medium; 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 be able to fully penetrate into the steam core area due to the high steam velocity, thus affecting the condensation effect. At this time, by activating the telescopic rod (106) near the outer wall of the condenser tube (1), the telescopic rod (106) near the outer wall of the condenser tube (1) extends and drives the blade (105) to rotate, thereby increasing the tilt angle of the blade (105) until the required angle is reached.

6. A steam condensation recovery device according to claim 5, characterized in that: The steps for adjusting the tilt angle of the third blade (602) are as follows: Before condensation, the impact angle between the steam and the third blade (602) is changed by starting the pump body (605), so that the angle between the third blade (602) and the horizontal plane is β. When steam enters the inlet (101), the temperature T of the steam is measured, and the value of the angle between the blade three (602) and the horizontal plane that needs to be adjusted is calculated. .

7. A steam condensation recovery device according to claim 6, characterized in that: The adjustment method for the third (602) blade is as follows: when At that time, the tangential force exerted by blade three (602) on the steam increases, resulting in an increase in the tangential velocity component v of the steam. θ The significantly increased high tangential velocity component generates stronger centrifugal force, causing the steam to adhere more tightly to the condenser tube wall and form 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 reduction in axial velocity component may trigger flow separation or vortex, resulting in uneven distribution of steam in the condenser tube (1), thus affecting the condensation effect; At this time, by starting the pump body (605), the impact angle between the steam and the three blades (602) is reduced.

8. A steam condensation recovery device according to claim 7, characterized in that: The adjustment method for the third (602) blade is as follows: when At that time, the tangential force exerted by blade three (602) on the steam decreases, resulting in a decrease in the tangential velocity component v of the steam. θ The centrifugal force generated by the low tangential velocity component is relatively small, and the steam cannot fully adhere to the wall of the condenser tube (1) to form a thicker condensate film, thus reducing the heat exchange efficiency. This leads to a reduction in the axial flow resistance of steam between the blades, and an increase in the axial velocity component v. 轴向 As the volume increases, steam tends to flow more along the axial direction, weakening the spiral flow characteristics and resulting in uneven flow distribution, thus affecting the condensation effect. At this time, by starting the pump body (605), the impact angle between the steam and the three blades (602) is increased.
