Description

Technical Field

[0001] The present invention relates to the technical field of steam recovery, and particularly to a constant-pressure steam spiral recovery device. Background Art

[0002] A large amount of steam is generated in industrial production. The steam contains a large amount of heat energy and some chemical substances. If directly discharged into the atmosphere, it will waste a large amount of heat energy and water resources, and some of the chemical substances will also have a certain impact on the environment. Therefore, it is necessary to recover and treat the steam.

[0003] At present, a steam recovery device uses the heat energy of steam to heat cold water. Specifically, a cold water pipe is arranged on the periphery of the steam pipe. When steam passes through the steam pipe, heat is transferred to the cold water in the cold water pipe to raise the temperature of the cold water. After the cold water is heated, it can be used for other purposes, thereby realizing the reuse of heat energy. And the steam after heat exchange will cool and condense, and can be collected as water resources. After retrieval, the Chinese utility model patent with the publication number CN210801118U discloses a fuel steam generator capable of recovering waste heat, including a support frame. A support bottom plate is installed on the support frame, and a heat preservation water tank is installed at the top end of the support bottom plate. A liquid outlet pipe is connected to the top side of the heat preservation water tank. A fixing plate is installed at the top end of the support frame, and a steam generator main body is installed at the top end of the fixing plate. An inner cylinder is installed in the steam generator main body, and a heat absorption conduit is wound around the outer wall of the inner cylinder. One end of the heat absorption conduit is hermetically connected to one end of the liquid outlet pipe, and the other end of the heat absorption conduit is hermetically connected to a water inlet interface, and a water inlet valve is connected to the water inlet interface; in this utility model, the water inlet valve is adjusted to slowly transport water into the heat absorption conduit. The water in the heat absorption conduit can absorb the residual temperature of the inner cylinder, which can not only quickly cool down the inner cylinder, but also make full use of the residual temperature. The generated warm water is stored in the heat preservation water tank and the hot water is used for other equipment.

[0004] Although this device can heat and reuse the water in the heat absorption conduit, it cannot control the temperature of the water after heat absorption. And when some other equipment uses water, there are certain requirements for the water temperature. If it is to be used, the water after heat absorption still needs to be heated or cooled to a certain extent. That is, the water after heat absorption by this device is not convenient to be directly used.

[0005] Therefore, the present invention provides a constant-pressure steam spiral recovery device to solve the above problems. Summary of the Invention

It can be flexibly adjusted according to the needs of other equipment, so that the heated cold water can be directly used for other equipment without further treatment, which is convenient to use.

[0021] 3. In the present invention, the liquid passing pipe includes a heat conduction part, and the heat is absorbed through the heat conduction part. The rest is a heat insulation part, which can play a certain heat preservation role for the heated cold water, thereby improving the utilization rate of heat. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will refer to the reference appendices Figures 1 to 8 to describe each embodiment of the present invention in detail. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0032] Embodiment 1

[0033] A constant-pressure steam spiral recovery device, as shown in the appendices Figure 1 includes a vertically arranged hollow housing 3. A steam pipe 1 is vertically penetrated through the housing 3. The upper and lower ends of the steam pipe 1 are used to connect corresponding pipes for intake and exhaust. An inlet pipe 2 is provided above the housing 3, and an outlet pipe 4 is provided below the housing 3. The inlet pipe 2 and the outlet pipe 4 are used to connect corresponding pipes for liquid inlet and liquid outlet. This part is the prior art and will not be elaborated here.

[0034] As shown in the appendices Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 8As shown in the figure, an upper plate body 6 is rotatably arranged near the upper side of the circumference of the steam pipe 1 located in the housing 3, and a control mechanism for controlling the rotation of the upper plate body 6 is provided. A plurality of upper liquid through holes 5 are formed in the upper plate body 6, and a liquid through pipe 9 is provided below the upper liquid through holes 5. The liquid through pipe 9 is made of a flexible material and can undergo a certain amount of torsional deformation. The upper liquid through holes 5 are used to receive the cold water discharged from the liquid inlet pipe 2 and discharge the cold water into the liquid through pipe 9. The liquid through pipe 9 is closely attached to the circumference of the steam pipe 1. A heat conduction part 901 is provided inside the liquid through pipe 9, that is, the liquid through pipe 9 includes a heat conduction part 901 and a heat insulation part. Specifically, the heat conduction part 901 can be referred to in the appendix Figure 8 As shown in the figure, the liquid through pipe 9 is in contact with the steam pipe 1 through the heat conduction part 901, so that the heat of the steam pipe 1 can be absorbed and transferred to the inside of the liquid through pipe 9. The inside can be insulated to a certain extent through the heat insulation part. A lower plate body 12 is slidably arranged near the lower side of the circumference of the steam pipe 1 in the vertical direction. Specifically, a slideway 10 is also provided in the housing 3, and the lower plate body 12 is also slidably arranged on the slideway 10. The slideway 10 assists the lower plate body 12 to move in the vertical direction. A plurality of lower liquid through holes 16 are provided on the lower plate body 12. The lower liquid through holes 16 are connected to one end of the liquid through pipe 9 far away from the upper liquid through holes 5. A liquid outlet pipe 4 is connected below the lower plate body 12. The liquid outlet pipe 4 is used to receive the heated cold water discharged from the liquid through pipe 9 and discharge the heated cold water. A fixing plate 14 is provided on the circumference of the steam pipe 1 below the lower plate body 12. An elastic member 15 is provided between the fixing plate 14 and the lower plate body 12. Specifically, the elastic member 15 can directly adopt a spring. The liquid outlet pipe 4 is fixedly connected to the fixing plate 14 and extends out of the housing 3 at one end far away from the lower plate body 12. During operation, by changing the relative positions of the upper plate body 6 and the lower plate body 12, the spiral winding mode of the liquid through pipe 9 on the steam pipe 1 is changed.

[0035] During specific use, the lower end of the liquid inlet pipe 2 is connected to each upper liquid through-hole 5 by a certain connecting pipe, the upper end of the liquid outlet pipe 4 is connected to each lower liquid through-hole 16 by a certain connecting pipe, the upper end of the liquid inlet pipe 2 is connected to an infusion pipe and a one-way valve is provided, the lower end of the liquid outlet pipe 4 is connected to a drain pipe and a one-way valve is provided, the upper end of the steam pipe 1 is connected to a gas transmission pipe and a one-way valve is provided, the lower end of the steam pipe 1 is connected to an exhaust pipe and a one-way valve is provided, and a constant-pressure gas supply system is equipped to supply constant-pressure gas to the steam pipe 1. During operation, first, a certain amount of cold water is input into the liquid through-pipe 9 through the liquid inlet pipe 2 so that the cold water stays in the liquid through-pipe 9 in advance. Subsequently, a certain amount of steam is introduced into the steam pipe 1 and discharged so that the time of the steam in the steam pipe 1 is fixed. During this time period, the heat of the steam is transferred to the cold water in the liquid through-pipe 9 through the heat-conducting part 901 of the steam pipe 1 and the liquid through-pipe 9. Then, the heated cold water can be discharged. When it is necessary to adjust the temperature of the heated cold water, by controlling the rotation of the upper plate body 6, the upper plate body 6 drives the upper end of the liquid through-pipe 9 to rotate. Since the lower end of the liquid through-pipe 9 is connected to the lower liquid through-hole 16 of the lower plate body 12, the lower end of the liquid through-pipe 9 and the lower plate body 12 cannot rotate. When the upper plate body 6 rotates, the lower end of the liquid through-pipe 9 and the lower plate body 12 move in the vertical direction, thereby changing the winding mode of the liquid through-pipe 9 on the steam pipe 1. Under the action of the elastic member 15, the liquid through-pipe 9 is stressed at both ends and can maintain balance, thereby changing the contact area between the heat-conducting part 901 of the liquid through-pipe 9 and the steam pipe 1, changing the heat transfer rate, and further changing and controlling the temperature of the heated cold water in the liquid through-pipe 9, so as to be convenient for direct use in other equipment.

[0036] In addition, it should be noted that the connection mode between the two ends of the liquid through-pipe 9 and the corresponding liquid through-holes in this embodiment should be a fixed connection, so that the liquid through-pipe 9 can be twisted when winding around the steam pipe 1, so as to realize the contact between the heat-conducting parts 901 with different areas and the steam pipe 1 and change the heat transfer rate.

[0037] In addition, it should be noted that during the actual operation of this embodiment, a corresponding electronic control system is required to control the inlet and outlet of gas and liquid, and a temperature sensor can be set in the liquid through-pipe 9 to detect the temperature in the liquid through-pipe 9.

[0038] In addition, it should be noted that during the actual operation of this embodiment, before putting it into operation, the position of the upper plate body 6 can be adjusted multiple times, and the real-time temperature can be detected by the temperature sensor, and finally adjusted to the required state before use. It should be noted that after each discharge of the heated cold water in this embodiment, the whole device needs to be stationary for a certain period of time. After the temperature of the whole device returns to the initial state, the next operation can be carried out. A temperature sensor can also be set in the steam pipe 1. When it is detected that the temperatures in the steam pipe 1 and the liquid through-pipe 9 return to the initial state, the next operation can be carried out, so as to ensure accurate control of the temperature of the heated cold water.

[0039] In addition, it should be noted that in this embodiment, the liquid delivery pipe 9 includes a heat conduction part 901, and the rest is a heat insulation part. Heat is absorbed through the heat conduction part 901, and the heated cold water can be kept warm to a certain extent through the heat insulation part, thereby preventing heat loss and improving the utilization rate of heat. In this embodiment, heat conduction is carried out through multiple liquid delivery pipes 9, and the whole cold water conduction is relatively uniform.

[0040] In addition, it should be noted that the principle in this embodiment is to change the heat transfer rate by changing the contact area between the heat conduction part 901 with different areas and the steam pipe 1. In addition to setting the heat conduction part 901 and the heat insulation part, the whole liquid delivery pipe 9 can also be set as the heat conduction part. When changing the winding mode of the liquid delivery pipe 9, the contact area with the steam pipe 1 will also be slightly changed. This structure can also achieve adjustment, but the adjustment range is relatively small.

[0041] Embodiment 2

[0042] As shown in the Figure 2 accompanying drawings, the difference from Embodiment 1 is that in this embodiment, the peripheral side of the upper plate body 6 is hermetically and rotatably connected to the housing 3, and the inner side is hermetically and rotatably connected to the steam pipe 1. The part of the steam pipe 1 located above the upper plate body 6 and the upper plate body 6 are both made of heat insulation materials. In this embodiment, the connecting pipe between the liquid inlet pipe 2 and the upper liquid through hole 5 can be omitted. Utilizing the space at the top of the housing 3, the cold water passing through the liquid inlet pipe 2 can be directly discharged into the liquid delivery pipe 9, and the space at the top of the housing 3 can store some cold water, increasing the water storage space and making the use more flexible.

[0043] As shown in the Figure 2 , Figure 3 , Figure 4 , Figure 6 accompanying drawings, the difference from Embodiment 1 is that in this embodiment, several upper liquid through holes 5 are arranged at equal intervals along the circumference at the inner side of the upper plate body 6. The lower end of the liquid delivery pipe 9 is fixedly connected to the lower liquid through hole 16. An upper limiting plate 7 is arranged below the upper plate body 6. The upper limiting plate 7 is annular, and the inner side is closely attached to the liquid delivery pipe 9. Several lower liquid through holes 16 are arranged at equal intervals along the circumference at the inner side of the lower plate body 12. A lower limiting plate 11 is arranged above the lower plate body 12. The lower limiting plate 11 is annular, and the inner side is closely attached to the liquid delivery pipe 9. In this embodiment, when the liquid delivery pipe 9 is distorted and deformed, through the limiting action of the upper limiting plate 7 and the lower limiting plate 11, it can assist the liquid delivery pipe 9 to be closely attached to the steam pipe 1 and ensure the heat conduction effect.

[0044] As shown in the Figure 2 , Figure 4 accompanying drawings, the difference from Embodiment 1 is that in this embodiment, ball bearings 17 are arranged on the inner sides of both the upper limiting plate 7 and the lower limiting plate 11, and the liquid delivery pipe 9 is closely attached through the ball bearings 17. The setting method of the ball bearings 17 in the lower limiting plate 11 can refer to the Figure 4, the ball 17 in the upper limit plate 7 is the same as it. In this embodiment, by setting the ball 17, the friction between the liquid delivery pipe 9 and the limit plate can be reduced when the liquid delivery pipe 9 moves relative to the steam pipe 1, enabling the liquid delivery pipe 9 to move normally without affecting the limiting function of the limit plate.

[0045] As shown in the appendix Figure 2 , Figure 7 As shown, the difference from the first embodiment is that in this embodiment, an annular chute 8 is provided on the steam pipe 1. The annular chute 8 is a groove. A connecting mechanism is provided between the annular chute 8 and the liquid delivery pipe 9. The connecting mechanism includes a slider 24 slidably disposed in the annular chute 8. A universal ball 22 is provided on the slider 24. The universal ball 22 is connected to a clamping member 23. The inner diameter of the clamping member 23 is adapted to the outer diameter of the liquid delivery pipe 9 and can slide and rotate relative to the liquid delivery pipe 9. The clamping member 23 can play a certain limiting role on the liquid delivery pipe 9. And when the liquid delivery pipe 9 moves, the clamping member 23 can be driven to make an adaptive movement through the slider 24 and the universal ball 22. In addition, it should be noted that in this embodiment, the clamping member 23 can be an arc structure adapted to the outer diameter of the liquid delivery pipe 9, which can be an arc structure equivalent to the outer diameter of the liquid delivery pipe 9, or a ring structure slightly larger than the outer diameter of the liquid delivery pipe 9, playing a certain limiting role on the liquid delivery pipe 9, so as to assist the liquid delivery pipe 9 to be close to the steam pipe 1.

[0046] As shown in the appendix Figure 2 , Figure 5 As shown, the difference from the first embodiment is that in this embodiment, the control mechanism includes an annular rack 18 provided on the upper plate body 6. Specifically, the annular rack 18 is provided below the upper plate body 6. The annular rack 18 is meshed with a gear 19. The gear 19 is connected to a motor 21. The motor 21 is electrically connected to a controller. A support plate 20 is provided between the motor 21 and the housing 3. When adjusting the rotation of the upper plate body 6, only need to control the motor 21 to rotate through the controller, which is convenient to operate. And in this embodiment, the rotating shaft of the motor 21 passes through the housing 3, and the motor 21 and the support plate 20 are arranged outside the housing 3, which is convenient for maintenance.

[0047] As shown in the appendix Figure 2 , Figure 4 As shown, the difference from the first embodiment is that in this embodiment, a liquid storage cavity 13 is provided below the lower plate body 12. The liquid storage cavity 13 is made of heat-insulating material. Both ends of the elastic member 15 are respectively connected to the liquid storage cavity 13 and the fixing plate 14. The liquid storage cavity 13 is communicated with the liquid delivery pipe 9 through a lower liquid passing hole 16. The liquid outlet pipe 4 is communicated with the liquid storage cavity 13. The liquid outlet pipe 4 is fixedly connected to the fixing plate 14, and the part between the fixing plate 14 and the liquid storage cavity 13 adopts a telescopic structure. In this embodiment, by setting the liquid storage cavity body 13, some cold water can be stored. Cooperating with the structure at the top of the housing 3, more cold water can be input in advance, making it more convenient to use.

[0048] During specific use, first, connect the upper end of the liquid inlet pipe 2 to an infusion pipe and install a one-way valve. Connect the lower end of the liquid outlet pipe 4 to a drain pipe and install a one-way valve. Connect the upper end of the steam pipe 1 to a gas transmission pipe and install a one-way valve. Connect the lower end of the steam pipe 1 to an exhaust pipe and install a one-way valve. At the same time, equip a constant-pressure gas supply system that can supply gas to the steam pipe 1 at a constant pressure. Then, drain a certain amount of cold water through the liquid inlet pipe 2. The height of the cold water can be higher than the upper plate body 6. Subsequently, introduce a certain amount of steam into the steam pipe 1 and then discharge it. After that, the temperature of the cold water after heating in the liquid passing pipe 9 can be detected by a temperature sensor. After adjusting the upper plate body 6 and detecting the temperature of the cold water after heating multiple times by the above method until the finally obtained cold water after heating meets the required temperature. During operation, each time a certain amount of cold water and steam are introduced successively, water at the required temperature can be obtained.

[0049] In this embodiment, connection support frames (not shown in the figure) are provided on the peripheral side of the housing 3. Multiple such devices can also be connected in parallel through the connection support frames. During operation, water at different temperatures can be obtained simultaneously, which can be directly used for various devices, making it more convenient to use.
