Abstract
Description
Technical Field
[0001] The present application relates to the field of heating technology, and more specifically, to a water tank type heating device and system. Background Art
[0002] With the increasing demand for heat production, ensuring the normal operation of thermal equipment is particularly important. Poor steam can damage thermal equipment and endanger user safety. To provide users with good steam quality, it is necessary to provide purer and more steam. The technology used for steam heating is to first fill a thermal storage tank with a certain mass of desalted water, and then fill it with high-temperature, high-pressure steam to heat and pressurize the water into high-temperature saturated water. The heat is stored in the saturated water. When it reaches the user side, due to the lower pressure on the user side, the high-temperature, high-pressure steam is released through the pressure difference between the user side and the tank to meet the user's gas demand.
[0003] Currently, phase-change materials are designed to be placed on the outer wall of the tank roof, facing the delivery pipeline, to maintain steam quality during transportation. However, in its solid state, the phase-change material doesn't fully contact the tank wall, creating cavities and slowing heat absorption. Furthermore, the tank has a certain thickness to withstand pressure, so it takes a long time for the internal temperature to transfer to the outer wall, making the phase-change material's heat absorption effect slow. Utility Model Content
[0004] In view of the above problems, the present application provides a water tank type heating device and system to increase the heat absorption rate of phase change materials.
[0005] In order to achieve the above objectives, the following specific plans are proposed:
[0006] A water tank type heating device comprises two phase change material areas, two steam supply / release pipes and a set of steam inlet / water inlet pipes, wherein the steam inlet / water inlet pipes comprise two steam inlet / water inlet manifolds;
[0007] Each of the phase change material regions comprises a phase change material;
[0008] Part of the pipe body of each steam supply / release pipe is wrapped in its corresponding phase change material area;
[0009] Part of the pipe body of the steam / water inlet branch on each side is wrapped in its corresponding phase change material area.
[0010] Preferably, the steam inlet / water inlet branch pipe and the steam supply / steam release pipe in each phase change material area are spaced apart by a preset distance.
[0011] Preferably, the steam / water inlet pipe also includes a main pipe into which the steam / water inlet branches on both sides converge.
[0012] A water tank type heating system, comprising the water tank type heating device as described above and a heat storage tank;
[0013] The two phase change material areas of the water tank type heating device are fixed vertically above the heat storage tank to cover the outer surface of the tank top of the heat storage tank;
[0014] The steam / water inlet pipe of the water tank type heating device leads to the interior of the heat storage tank.
[0015] Preferably, the main pipeline to which the steam / water inlet branches on both sides of the steam and water inlet pipes merge is located in the heat storage tank.
[0016] Preferably, the heat storage tank includes a steam inlet branch pipe;
[0017] The main pipeline is connected to the steam inlet branch pipe.
[0018] Preferably, the steam inlet branch pipe extends from the front of the tank body to the rear of the tank body of the heat storage tank.
[0019] Preferably, the main pipeline is connected to the head of the steam inlet branch pipe, or the main pipeline is connected to the middle section of the steam inlet branch pipe.
[0020] Preferably, the steam inlet branch pipe is connected to a plurality of gas distribution pipes.
[0021] Preferably, the heat storage tank is provided with a sensor interface, to which a gate valve and a regulating valve are connected.
[0022] By utilizing the above-described technical solution, the water tank heating device of the present application includes two phase change material zones, two steam supply / discharge pipes, and a set of steam inlet / water inlet pipes. Each phase change material zone wraps around a portion of the steam inlet / water inlet pipes and the steam supply / discharge pipes. As can be seen, the phase change material tube layer directly contacts the steam supply / discharge pipes and the steam inlet / water inlet pipes. When desalted water is introduced through the steam inlet / water inlet pipes, the phase change material can fully absorb heat from the steam inlet / water inlet pipe walls. Compared to absorbing the heat of the heated desalted water within the tank by adhering to the tank wall, direct heat absorption from the steam inlet / water inlet pipe walls is more efficient, thereby improving steam transmission efficiency.

[0028] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0029] The embodiment of the present application provides a water tank type heating device, such as Figure 1 and Figure 2 As shown, the water tank type heating device may include: two phase change material areas, two steam supply / release pipes and a set of steam inlet / water inlet pipes. The steam inlet / water inlet pipes may include two steam inlet / water inlet manifolds, and each phase change material area includes phase change material.
[0030] Part of the pipe body of each steam supply / steam exhaust pipe is wrapped in its corresponding phase change material area. Part of the pipe body of each side steam inlet / water inlet branch is wrapped in its corresponding phase change material area.
[0031] It's understood that the steam / water inlet pipes are used to charge high-temperature, high-pressure steam into the tank. During this process, the PCM layer surrounding the pipes absorbs sufficient heat from the pipe walls, rapidly transitioning from a solid state to a liquid state in a short period of time, allowing the PCM layer to quickly reach a state sufficient to maintain heat retention in the steam supply / discharge pipes. When steam needs to be discharged through the pipes, the PCM layer surrounding the pipes insulates and heats the steam within them through heat conduction, maintaining the quality of the output steam.
[0032] Furthermore, considering that the steam supply / exhaust pipe is fully heated by the phase change material, the phase change material can fully wrap the steam supply / exhaust pipe. In this case, in order to allow the phase change material to provide more contact area with the steam supply / exhaust pipe, the steam inlet / water inlet manifold can be avoided from contacting the steam supply / exhaust pipe. Therefore, in each phase change material area, the steam inlet / water inlet manifold and the steam supply / exhaust pipe are separated by a preset spacing distance.
[0033] Furthermore, the steam / water inlet pipe also includes a main pipe into which the steam / water inlet branches on both sides merge.
[0034] Specifically, such as Figure 1 and Figure 2 As shown, two phase change material areas are located on both sides, and the steam / water inlet pipes wrapped by the two phase change material areas can merge in the middle to allow high-temperature and high-pressure steam to merge into the main pipe.
[0035] The water tank heating device provided in this embodiment includes two phase change material zones, two steam supply / exhaust pipes, and a set of steam inlet / water inlet pipes. Each phase change material zone wraps around a portion of the steam inlet / water inlet pipes and the steam supply / exhaust pipes. As can be seen, the phase change material tube layer directly contacts the steam supply / exhaust pipes and the steam inlet / water inlet pipes. When desalted water is introduced through the steam inlet / water inlet pipes, the phase change material can fully absorb heat from the steam inlet / water inlet pipe walls. Compared to absorbing the heat of the heated desalted water within the tank by adhering to the tank wall, direct heat absorption from the steam inlet / water inlet pipe walls is more efficient, thereby improving steam transmission efficiency.
[0036] The embodiment of the present application provides a water tank type heating system, such as Figure 3 and Figure 4 As shown, the water tank type heating system may include: a water tank type heating device and a heat storage tank.
[0037] Among them, such as Figure 3 As shown, the two phase change material areas of the water tank type heating device are fixed vertically above the thermal storage tank to cover the outer surface of the tank top of the thermal storage tank. The steam / water inlet pipe of the water tank type heating device leads to the interior of the thermal storage tank.
[0038] Specifically, when the heat storage tank is filled with high-temperature steam, the high-temperature steam in the steam / water inlet pipe heats the phase change material, and part of the heat is stored in the material. When the tank temperature rises, the phase change material can also be heated.
[0039] It can be understood that the steam / water inlet manifolds on both sides are two small branches outside the tank body, which can increase the reliability of the steam inlet pipeline, and the steam / water inlet pipes and steam supply / steam release pipes are connected to the tank body in the same small area, which is convenient for manufacturing and maintenance.
[0040] Further, such as Figure 3 As shown, the main pipe to which the steam / water inlet branches on both sides of the steam / water inlet pipe merge can be located in the heat storage tank.
[0041] Specifically, the steam / water inlet manifolds on both sides can be merged into a main pipe at the top of the heat storage tank, and then bend downward to extend into the heat storage tank, so that high-temperature steam can be input into the heat storage tank to heat the desalted water at room temperature.
[0042] Further, such as Figure 4As shown, the thermal storage tank includes a steam inlet branch pipe connected to multiple gas distribution pipes, which are used to evenly deliver high-temperature, high-pressure steam to heat the desalted water in the thermal storage tank. The thermal storage tank may also have a sensor interface connected to a gate valve and a regulating valve. Specifically, the sensor interface can be connected to the regulating valve via a gate valve.
[0043] It can be understood that since the steam inlet branch pipe is used to transport high-temperature and high-pressure steam to the normal-temperature desalted water in the heat storage tank, the main pipeline of the steam / water inlet pipe can be connected to the steam inlet branch pipe.
[0044] Furthermore, the steam inlet branch pipe can extend from the front of the heat storage tank to the rear of the tank to uniformly release high-temperature and high-pressure steam to the room-temperature desalted water in each compartment of the heat storage tank, so as to uniformly heat the room-temperature desalted water in each compartment.
[0045] Furthermore, the main pipeline can be connected to the head of the steam inlet branch pipe so that the head of the steam inlet branch pipe serves as the source of high-temperature and high-pressure steam, releasing high-temperature and high-pressure steam from the head to the tail to the normal-temperature desalted water in each section of the tank body.
[0046] In addition, the main pipeline can also be connected to the middle section of the steam inlet branch pipe, so that the middle section of the steam inlet branch pipe serves as the source of high-temperature and high-pressure steam, transmitting high-temperature and high-pressure steam to the head and tail respectively, and can also release high-temperature and high-pressure steam to the normal temperature desalted water in each section of the tank body.
[0047] Next, the process of steam transportation in a water tank heating system is introduced.
[0048] S1. Fill the heat storage tank with sufficient desalted water at room temperature.
[0049] S2. High-temperature and high-pressure steam is transported through the steam / water inlet pipe. The high-temperature and high-pressure steam from the steam / water inlet branches on both sides are merged into the main pipe, and then the high-temperature and high-pressure steam is transmitted to the steam inlet branch pipe through the main pipe. Then, the high-temperature and high-pressure steam is output from each gas distribution pipe on the steam inlet branch pipe to heat the normal-temperature desalted water in the thermal storage tank.
[0050] Specifically, in the process of transporting high-temperature and high-pressure steam through the steam / water inlet pipe, the phase change material pipe layer can be quickly heated because the phase change material pipe layer wraps the steam / water inlet pipe.
[0051] At the same time, since the phase change material area of the water tank type heating device covers the outer surface of the tank top of the heat storage tank, when the desalted water at room temperature is heated, the heat storage tank will heat up, and the phase change material area in the water tank type heating device can absorb heat through the outer surface of the tank top.
[0052] S3. When steam needs to be delivered to the user side, steam is delivered to the user side through the steam supply / release pipe.
[0053] It is understandable that since the phase change material pipe layer is preheated, the phase change material pipe layer can insulate and heat the steam supply / release pipe by heat conduction to maintain the quality of the steam being transported.
[0054] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
