Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation systems, in particular to a thermal insulation system with a heating tape and slow release water heating. Background Art

[0002] The electric heating cable is composed of a conductive polymer and two parallel metal wires and an insulating sheath. Its characteristics are that the conductive polymer has a very high positive temperature coefficient characteristic, and is connected in parallel with each other, and can automatically adjust the output power with the temperature change of the heated system, automatically limit the heating temperature, can be arbitrarily shortened or extended within a certain range, and allows multiple cross-overs without the worry of high-temperature hot spots and burning.

[0003] The existing insulation systems based on heating tapes are generally used commercially in various farms, pipelines, boilers, floor heating and other fields. They are commonly used for preheating, heating and insulation functions.

[0004] The above-mentioned existing technical solutions have the following defects. When the electric heating tape is combined with the photovoltaic power generation system for use in the wild or remote areas, it is often necessary to cooperate with a large-capacity energy storage system. However, the large-capacity battery pack has the problems of heavy weight, complex manufacturing process and high cost, and high difficulty in thermal management, which limits its applicable scenarios. Therefore, a low-cost auxiliary system is needed to facilitate auxiliary heating and energy storage to reduce the demand for large-capacity battery packs. Summary of the invention

[0005] The object of the present invention is to provide a thermal insulation system with a slow release of heated water heating.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A thermal insulation system with a heating tape and water heating slow release comprises a power module for providing electric energy, a water heat storage module, a circulation purification pipeline, a heating tape module and a water heating module, wherein the power module is electrically connected to the heating tape module and the water heat storage module, the water heat storage module is connected to the water heating module via a circulation purification pipeline, the heating tape module is integrated with the water heating module, the power module comprises a controller module, a wind generator set, a solar generator set and a battery pack, the wind generator set, the solar generator set and the battery pack are electrically connected to the controller module, and the wind generator set and the solar generator set are equipped with an inverter and a converter.

[0008] By adopting the above technical solution, when used outdoors or in the event of a power outage, in order to maintain a lasting heating effect, compared with the solution of increasing the capacity of the battery pack, the added water heat storage module, in cooperation with the circulating purification pipeline and the water heating module, has a good auxiliary heating effect. Compared with the traditional battery pack energy storage, the two energy storage methods of electric energy storage and water heat storage are adopted, which can effectively reduce the demand for the capacity of the battery pack.

[0009] First of all, when one of the energy storage devices is damaged, the other energy storage device can still play a role in performing limited preheating and heating work, avoiding equipment shutdown and affecting production. The increase in the energy storage method improves the stability and reliability of the heating system.

[0010] Secondly, due to the reduction of the battery pack capacity, the battery pack has lower requirements for heat dissipation capacity, and the battery management system of the battery pack is also easier to control the temperature of the battery pack. Moreover, due to the decrease in the number of battery cells, voltage balance is easier to adjust, which can effectively reduce the risk of accidents caused by thermal runaway of the battery pack.

[0011] Then, due to the long-term charge and discharge cycle of the battery pack, before reaching the cycle life or calendar life, the internal resistance will continuously increase, the battery capacity will decrease, the power loss will increase, and the energy utilization efficiency will also be lower. The main energy loss of the water heat storage module lies in the external heat dissipation. Various heat preservation means can be adopted to improve the energy utilization efficiency. Compared with the energy conversion method of charging the battery pack and then preventing electricity from generating heat, the water heat storage energy storage can be carried out by directly connecting the power supply module through energy shunting via the controller module, and the hot water can be directly used for heating, omitting the intermediate charge and discharge conversion. On the premise of doing a good job in heat preservation and heat insulation measures, the energy conversion rate will be much higher than the heating efficiency of the battery pack input current control with a heat tracing module.

[0012] Finally, the power supply module adopts wind-solar complementary power generation, which can effectively utilize the wind energy and light energy in the environment to continuously and stably supply energy to the heating system, and can also be connected to the commercial power as a further supplementary power source, maximizing the guarantee of the continuity and stability of energy supply.

[0013] Furthermore, the water heat storage module includes a heat storage pool. The top wall of the heat storage pool is provided with a water storage tank filled with sufficient water. The inner wall of the water storage tank is fixedly installed with a number of heating rods. The heat storage pool is a double-layer vacuum shell, and the inside of the double-layer vacuum silver-plated shell is silver-plated. The water storage tank is covered with a heat preservation cover plate. The heat storage pool is wrapped with a heat preservation layer. The outer wall of the heat storage pool is fixedly provided with a water injection pump connected to the water storage tank, and the water injection pump is externally connected to a water supply pipeline.

[0014] Furthermore, the circulating purification pipeline includes a water outlet pump connected to the water storage tank and a purifier. The water outlet pump is connected with a main water outlet pipe, and the purifier is connected with a main water return pipe. A water distribution and collection device is arranged between the main water outlet pipe and the main water return pipe. The water distribution and collection device is connected with a number of groups of water outlet branch pipes and water return branch pipes. The water outlet branch pipes and the water return branch pipes are connected to the water heating module. The water injection pump, the heating rod and the water outlet pump are electrically connected to the power supply module and the controller module.

[0015] Furthermore, the water distribution and collection device includes a water distributor connected to the main water outlet pipe and a water collector connected to the main water return pipe. A number of water outlet openings connected to the water outlet branch pipes are arranged on the outer wall of the water distributor, and a water return opening connected to the water return branch pipe is arranged on the outer wall of the water collector. An exhaust valve is connected to the water distributor, and a drain valve is connected to the water collector. The height of the exhaust valve is higher than that of the drain valve.

[0016] Furthermore, the heat tracing belt module is strip-shaped and spirally wound around the outer wall of the water heating module. The water heating module is a high-temperature resistant pipeline structure.

[0017] Furthermore, thermometers are fixedly arranged on the inner wall of the water storage tank and the outer wall of the water heating module. A liquid level gauge is arranged on the inner wall of the water storage tank. A wattmeter is electrically connected to the wind power generation set, the solar power generation set, the battery pack, the water injection pump, the water outlet pump, the heating rod and the heat tracing belt module. The thermometers, the liquid level gauge and the wattmeter are connected to the controller module. The controller module is equipped with an electronic display screen.

[0018] By adopting the above technical solution, the water heating module is installed on the outer wall of the item to be heated. During installation, the thermometer on the outer wall is closely attached to the equipment to be heated. When the temperature of the equipment to be heated is lower than the system set temperature, the heating system is started for heating. The electronic display screen will display the monitoring data of each sensor in real time, which is convenient for the operator to understand the working state of the system.

[0019] The electric heating method is as follows: The heat tracing belt module is energized to generate heat by the wind power generation set, the solar power generation set, the battery pack or the commercial power supply. Since the water heating module is spirally wound around the outer wall of the equipment to be heated, the heat tracing belt module spirally wound around the water heating module can also be closely attached to the equipment to be heated for heat conduction, effectively performing high-temperature heating above 90 degrees. The heating range is higher than that of the water heating module. When a higher heating temperature is required, the water outlet pump is turned off, and the exhaust valve and the drain valve are opened to empty the aqueous solution in the water heating module. This can not only prevent the heat taken away by the flow of the aqueous solution in the water heating module from affecting the heating effect, but also prevent the aqueous solution from boiling during heating from damaging the water heating module.

[0020] The water heating method is as follows: When the water level gauge detects that the water volume in the water storage tank is insufficient, the controller module will start the water injection pump to inject water until the water volume in the water storage tank reaches the threshold set by the system. The heating rod heats the water in the water storage tank through the power supply of the wind power generation unit, solar power generation unit, battery pack or mains power. After reaching the temperature set by the system, the heating stops. When the water temperature reaches the heating standard, the water outlet pump is turned on, and the hot water enters the water heating module through the main water outlet pipe and branch water outlet pipes. The water heating module heats the equipment to be heated in the temperature range of 50 - 90 degrees. The cooled water then flows back into the water storage tank through the branch water return pipe and main water return pipe. When the capacity of the water storage tank is large enough, the heat release is relatively slow, enabling long-term temperature drop cyclic heating when the power supply is insufficient.

[0021] The energy storage and distribution method is as follows: In the starting stage, the water injection pump is turned off, and the power is preferentially supplied to the heating tape module for rapid heating to quickly bring the equipment to be heated to the required temperature. After reaching the predetermined temperature, part of the power is allocated to the water injection pump for water replenishment. After the replenishment is completed, the water injection pump is turned off, and the remaining power is allocated to the heating rod for water heat storage. When the water temperature reaches an appropriate temperature, the required heating temperature range is judged by a thermometer. When the temperature range is between 50 - 90 degrees, the power is dynamically adjusted and distributed to the water outlet pump and the heating tape module for combined water, electricity, and heating or pure water heating slow release. When the temperature range is greater than or equal to 90 degrees, the water heating module is emptied, and all the power is supplied to the heating tape module for high-temperature heating.

[0022] When the power generation is higher than the total heating power, the heating rod is further supplied to raise the water temperature, and the power of the heating tape module is reduced to ensure that the excess power is used for water heating energy storage and charging into the battery pack for energy storage. When the power generation is lower than the total heating power, the flow rate of the water outlet pump is preferentially increased to improve the water heating rate. When the water heating is lower than the temperature range requirement, the water outlet pump is turned off, and the water heating module is emptied. The battery powers the heating tape module for heating. When the battery power is lower than the set value, the energy of the battery pack and the heat storage tank is completely released at this time. The operator can connect the mains power for energy supply according to the prompt. When the designed power generation has sufficient energy redundancy, generally there is no need to connect the mains power for energy supplementation, and only in the case of long-term high-temperature heating or long-term low light and low wind conditions is it necessary to switch to the mains power for energy supplementation.

[0023] In summary, the beneficial technical effects of the present invention are as follows:

[0024] 1. By adopting the water heat storage module, circulating purification pipeline, heating tape module and water heating module, while achieving good auxiliary heating, the demand for the capacity of the battery pack is effectively reduced.

[0025] 2. The water heating module thermometer, liquid level gauge, power meter and electronic display screen are adopted. The settings of each sensor can effectively monitor the operation of the system, and cooperate with the control system to produce the effect of intelligent control of the heating system;

[0026] 3. The heat tracing module and the water heating module are integrally arranged. When installing the water heating module, the heat tracing module is installed at the same time, which improves the installation effect. At the same time, the heat tracing module is spirally wound on the outer wall of the water heating module, increasing the heating length and heating area of the heat tracing module, and the heating rate can be further improved. At the same time, it has good flexibility when receiving tensile force and can avoid damage;

[0027] 4. The water distributor, water collector, exhaust valve and drain valve are adopted, which can be adapted to several groups of water heating modules. It can not only be installed centrally in combination to improve the heating rate, but also be installed separately on several groups of equipment to be heated for large-scale heating. The settings of the exhaust valve and drain valve facilitate the evacuation of the water heating module for high-temperature heating of the heat tracing module, effectively improving the matching degree between the heat tracing module and the water heating module;

[0028] 5. The double-layer vacuum shell, the heat storage pool with silver plating inside, the heat preservation cover plate and the heat preservation layer are adopted. By blocking heat radiation and heat convection, and cooperating with the heat preservation cover plate and the heat preservation layer made of heat preservation materials, the water storage pool is wrapped all-round to prevent heat dissipation and energy loss. At the same time, the heat storage pool can be buried underground to further block heat dissipation, and has excellent heat preservation and heat insulation effects. When necessary, several groups of water heating modules can also be used as waste heat collection pipelines to collect waste heat in the high-temperature areas of the equipment to be heated, such as collecting waste heat generated by a high-temperature boiler for catalytic decomposition heating of the exhaust gas in the exhaust pipe.

Detailed implementation mode

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0038] A heat preservation system with heat tracing and water heating slow release includes a power supply module 1 for providing electric energy, a water heat storage module 2, a circulating purification pipeline 3, a heat tracing module 4 and a water heating module 5. The power supply module 1 is electrically connected to the heat tracing module 4 and the water heat storage module 2. The water heat storage module 2 is connected to the water heating module 5 through the circulating purification pipeline 3. The heat tracing module 4 and the water heating module 5 are integrally arranged. The power supply module 1 includes a controller module 11, a wind power generation set 12, a solar power generation set 13 and a battery pack 14. The wind power generation set 12, the solar power generation set 13 and the battery pack 14 are electrically connected to the controller module 11. The wind power generation set 12 and the solar power generation set 13 are equipped with inverters and converters.

[0039] When used outdoors or in the event of a power outage, in order to maintain a lasting heating effect, compared with the solution of increasing the capacity of the battery pack 14, the added water heat storage module 2, in cooperation with the circulating purification pipeline 3 and the water heating module 5, has a good auxiliary heating effect. Compared with the traditional battery pack 14 energy storage, two ways of electric energy storage and water heat storage are adopted, which can effectively reduce the demand for the capacity of the battery pack 14.

[0040] First, when one of the energy storage devices is damaged, the other energy storage device can still function to perform limited preheating and heating operations, avoiding equipment shutdown and affecting production. The increase in the energy storage method improves the stability and reliability of the heating system.

[0041] Secondly, due to the reduced capacity of the battery pack 14, the battery pack 14 has lower requirements for heat dissipation capacity. The battery management system of the battery pack 14 is also more easily able to control the temperature of the battery pack 14. Moreover, due to the decrease in the number of battery cells, voltage equalization is also easier to adjust, which can effectively reduce the risk of accidents caused by thermal runaway of the battery pack 14.

[0042] Then, due to the long-term charge and discharge cycles of the battery pack 14, before reaching the cycle life or calendar life, the internal resistance will continuously increase, the battery capacity will decrease, the power consumption will increase, and the energy utilization efficiency will also be lower. The main energy loss of the water thermal storage module 2 lies in the external heat dissipation. Various heat insulation means can be adopted to improve the energy utilization efficiency. Compared with the energy conversion method of charging the battery pack 14 and then preventing it from generating heat through electricity, the water thermal storage can be carried out by directly connecting the energy shunt to the power supply module 1 via the controller module 11, and the hot water can be directly used for heating, omitting the intermediate charge and discharge conversion. On the premise of doing a good job in heat insulation measures, the energy conversion rate will be much higher than the heating efficiency of the battery pack 14 input current controlled heating tape module 4.

[0043] Finally, the power supply module 1 uses wind-solar complementary power generation, which can effectively utilize the wind energy and light energy in the environment to continuously and stably supply energy to the heating system. It can also be connected to the commercial power as a further supplementary power source, maximizing the guarantee of the continuity and stability of the energy supply.

[0044] The water thermal storage module 2 includes a heat storage pool 21. The top wall of the heat storage pool 21 is provided with a water storage tank 22 filled with sufficient water. A number of heating rods 6 are fixedly installed on the inner wall of the water storage tank 22. The heat storage pool 21 is a double-layer vacuum shell, and the inside of the double-layer vacuum silver-plated shell is silver-plated. The water storage tank 22 is covered with a heat insulation cover plate 23. The heat storage pool 21 is wrapped with a heat insulation layer. An injection pump 24 communicating with the water storage tank 22 is fixedly provided on the outer wall of the heat storage pool 21, and the injection pump 24 is externally connected to a water supply pipeline 25.

[0045] The circulating purification pipeline 3 includes a water outlet pump 31 and a purifier 32 that are connected to the water storage tank 22. The water outlet pump 31 is connected with a main water outlet pipe 311, and the purifier 32 is connected with a main return water pipe 321. A water distributor 33 is arranged between the main water outlet pipe 311 and the main return water pipe 321. The water distributor 33 is connected with a number of groups of water outlet branch pipes 312 and return water branch pipes 322. The water outlet branch pipes 312 and the return water branch pipes 322 are connected to the water heating module 5. The water injection pump 24, the heating rod 6 and the water outlet pump 31 are electrically connected to the power supply module 1 and the controller module 11.

[0046] The water distributor 33 includes a water distributor 331 connected to the main water outlet pipe 311 and a water collector 332 connected to the main return water pipe 321. The outer wall of the water distributor 331 is provided with a number of water outlet openings connected to the water outlet branch pipes 312, and the outer wall of the water collector 332 is provided with a water return opening connected to the return water branch pipe 322. The water distributor 331 is connected with an exhaust valve 34, and the water collector 332 is connected with a drain valve 35. The height of the exhaust valve 34 is higher than that of the exhaust valve 34.

[0047] The heat tracing tape module 4 is strip-shaped and spirally wound around the outer wall of the water heating module 5. The water heating module 5 is a high-temperature resistant pipeline structure.

[0048] A thermometer is fixedly arranged on the inner wall of the water storage tank 22 and the outer wall of the water heating module 5, and a liquid level gauge is arranged on the inner wall of the water storage tank 22. The wind power generator set 12, the solar power generator set 13, the battery pack 14, the water injection pump 24, the water outlet pump 31, the heating rod 6 and the heat tracing tape module 4 are electrically connected with a wattmeter. The thermometer, the liquid level gauge and the wattmeter are connected to the controller module 11, and the controller module 11 is equipped with an electronic display screen.

[0049] The water heating module 5 is installed on the outer wall of the item to be heated. During installation, the thermometer on the outer wall is closely attached to the equipment to be heated. When the temperature of the equipment to be heated is lower than the system set temperature, the heating system is started for heating. The electronic display screen will display the monitoring data of each sensor in real time, which is convenient for the operator to understand the working state of the system.

[0050] The electric heating method is as follows: The heating tape module 4 is energized to generate heat by means of a wind power generation unit 12, a solar power generation unit 13, a battery pack 14 or the mains power supply. Since the water heating module 5 is spirally wound around the outer wall of the device to be heated, the heating tape module 4 spirally wound around the water heating module 5 can also be in close contact with the device to be heated to conduct heat, effectively performing high-temperature heating above 90 degrees. The heating range is higher than that of the water heating module 5. When a higher heating temperature is required, the water outlet pump 31 is turned off, and the exhaust valve 34 and the drain valve 35 are opened to empty the aqueous solution in the water heating module 5, which can not only prevent the heat carried away by the flow of the aqueous solution in the water heating module 5 from affecting the heating effect, but also prevent the aqueous solution from boiling during heating from damaging the water heating module 5.

[0051] The water heating method is as follows: When the liquid level gauge detects that the water volume in the water storage tank 22 is insufficient, the controller module 11 will start the water injection pump 24 to carry out the water injection work until the water volume inside the water storage tank 22 reaches the threshold set by the system. The heating rod 6 heats the water in the water storage tank 22 through the power supply of the wind power generation unit 12, the solar power generation unit 13, the battery pack 14 or the mains power supply. After reaching the temperature set by the system, the heating is stopped. When the water temperature reaches the heating standard, the water outlet pump 31 is turned on, and the hot water enters the water heating module 5 through the water outlet main pipe 311 and the water outlet branch pipe 312. The water heating module 5 heats the device to be heated in the temperature range of 50-90 degrees. The cooled water then flows back into the water storage tank again through the water return branch pipe 322 and the water return main pipe 321. When the capacity of the water storage tank is large enough, the heat release is relatively slow, so that when the power supply is insufficient, long-term temperature slow-drop cycle heating can be carried out.

[0052] The energy storage and distribution method is as follows: In the starting stage, the water injection pump 24 is turned off at this time, and the heating tape module 4 is preferentially supplied to quickly heat the device to be heated to reach the required temperature. After reaching the predetermined temperature, part of the power is allocated to the water injection pump 24 to supplement the water volume. After the supplement is completed, the water injection pump 24 is turned off and the remaining power is allocated to the heating rod 6 for water heat storage work. When the water temperature reaches the appropriate temperature, the required heating temperature range is judged by the thermometer at this time. When the temperature range is between 50-90 degrees, the power is dynamically adjusted and distributed to the water outlet pump 31 and the heating tape module 4 for combined water and electric heating or pure water heating slow release. When the temperature range is greater than or equal to 90 degrees, the water heating module 5 is emptied, and all the power is supplied to the heating tape module 4 for high-temperature heating.

[0053] When the power generation power is higher than the total heating power, the heating rod 6 is further supplied to raise the water temperature and reduce the power of the heating tape module 4 to ensure that the excess power is used for water heating energy storage and charging into the battery pack for energy storage. When the power generation power is lower than the total heating power, the flow rate of the water pump 31 is preferentially increased to improve the water heating rate. When the water heating is lower than the temperature range requirement, the water pump 31 is turned off, the water heating module 5 is emptied, and the battery powers the heating tape module 4 for heating. When the battery power is lower than the set value, the energy of the battery pack 14 and the heat storage tank 21 is completely released at this time. The operator can connect the mains power supply for energy supply according to the prompt. When the designed power generation has sufficient energy redundancy, it is generally not necessary to connect the mains power supply for energy supplementation, and it is only necessary to switch to the mains power supply for energy supplementation in the case of long-term high-temperature heating or long-term low light and low wind.
