Description

Technical Field

[0001] This utility model relates to the field of steam equipment technology, and in particular to industrial steam equipment. Background Technology

[0002] Currently, some industrial production processes require steam heating for molding or steam-insulated shaping. The steam needed is primarily produced by boilers, which use fuel to heat water, vaporizing it into high-temperature, high-pressure steam. The main fuels are coal, oil, and natural gas. However, coal-fired boilers are environmentally unfriendly, with high sulfur content and exhaust gases that severely pollute the air. Furthermore, storing coal requires significant space and generates a lot of dust. Oil-fired boilers suffer from high fuel prices, high operating costs, and high risks associated with fuel transportation and storage, making them prone to accidents. Natural gas boilers are limited to areas with gas pipelines, which are unavailable in some underdeveloped regions. They also suffer from uneven combustion rates and heat radiation, significantly impacting steam generation rate and quality. Subsequently, electric heating for steam production emerged, offering a better solution to these boiler-related problems. However, existing electric steam generators consume large amounts of electricity, especially during peak hours when electricity prices are high, and have low steam production efficiency, resulting in high operating costs and hindering business development. Furthermore, the current steam production process has a relatively high moisture content in the steam, which affects the temperature rise of the steam. In addition, moisture tends to accumulate in the production equipment and transmission pipelines, causing oxidation and corrosion of the equipment and pipelines and affecting their service life. Summary of the Invention

[0003] The purpose of this utility model is to provide a heat storage adsorption heat pump steam unit that utilizes heat pump technology in conjunction with heat storage. This not only solves the technical problems of boiler combustion in steam production and reduces electricity consumption and operating costs, but also improves the moisture content of the steam, resulting in drier steam, which is beneficial for industrial production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The thermal storage adsorption heat pump steam unit has the following characteristics:

[0006] Insulated water tank,

[0007] The heat pump unit is connected to the insulated water tank through water pipes to form a water circulation heat exchange system, so that the water in the insulated water tank is heated by heat exchange through the heat pump unit.

[0008] An electromagnetic heating atomizing unit is installed downstream of an insulated water tank. The electromagnetic heating atomizing unit heats the hot water provided by the insulated water tank to form atomized gas.

[0009] The thermal storage tank is used to heat the atomized gas output from the electromagnetic heating atomizing unit to form superheated steam. Both the input and output ends of the thermal storage tank are equipped with dewatering structures to reduce the moisture content of the steam and obtain dry, high-pressure steam suitable for industrial production.

[0010] The above solution is further described in that the water removal structure includes a tank and water removal material filled in the tank. The tank is connected to a heat storage tank and / or an electromagnetic heating atomizing unit through a pipe. When the atomized gas or superheated steam passes through the tank and flows through the water removal material, the water removal material removes the moisture in the atomized gas or superheated steam by adsorption and separation.

[0011] A further aspect of the above scheme is that the tank is vertically arranged, with the atomized gas entering the tank from the top and moving downwards before being output; while the superheated steam enters the tank from the bottom and moves upwards before being output.

[0012] Furthermore, the water-removing material described above is nanocrystalline stone.

[0013] The above scheme is further described in that the heat storage tank includes an insulating outer shell and high-temperature molten salt disposed inside the insulating outer shell. The high-temperature molten salt is used to store heat and heat the atomized gas entering the heat storage tank, so that the atomized gas is heated to generate superheated steam.

[0014] The above scheme is further described in that the electromagnetic heating atomizing unit includes two heating barrels arranged in parallel. The two heating barrels draw water from the heat preservation water tank for heating, and then the output ends of the two heating barrels are combined to output atomized gas. The atomized gas is supplied to the heat storage tank after passing through the corresponding water removal structure.

[0015] The above scheme is further described as follows: the heating barrel includes a vertical columnar container, a heat-conducting filter material disposed inside the columnar container, and an electromagnetic heating component disposed on the outer periphery of the columnar container; hot water provided by the insulated water tank flows from top to bottom through the interior of the columnar container, and the hot water exchanges heat with the heat-conducting filter material to generate atomized gas; the electromagnetic heating component is energized to heat the hot water and the heat-conducting filter material inside the columnar container.

[0016] A further aspect of the above scheme is that the interior of the columnar container is constructed with a serpentine flow channel, allowing the hot water to move in a serpentine pattern and vaporize upon heating.

[0017] A further improvement in the above scheme is that the thermally conductive filter material is stainless steel fiber.

[0018] This invention employs heat pump heating technology combined with a heat storage method, optimizing the unit structure. The heat pump system itself has excellent energy-saving performance; combining it with an insulated water tank achieves energy storage and utilization, resulting in high energy efficiency and even more significant energy savings. The heat storage tank can pre-store heat, fully utilizing working intervals to store heat and achieve peak-shifting electricity use, greatly reducing operating costs. Simultaneously, the hot water provided by the insulated water tank is atomized into atomized gas by an electromagnetic heating atomizer before exchanging heat with the heat storage tank, further enhancing the heating effect and improving thermal efficiency, which helps reduce operating costs. Furthermore, dehydration structures are installed at both the input and output ends of the heat storage tank to reduce the moisture content of the steam, achieving two-stage dehydration and helping to obtain dry, high-pressure steam suitable for industrial production. The entire system has a simple and reliable structure, stable and safe operation, low investment cost, and solves the technical problems existing in boiler combustion steam production, effectively reducing electricity consumption and operating costs, making it suitable for industrial application.

[0022] The following will further explain the concept, specific structure and technical effects of the utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the utility model.

[0023] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0024] See Figure 1 , 2 Figure 3 shows a schematic diagram of a preferred embodiment of the present invention. The present invention relates to a heat storage adsorption heat pump steam unit, which includes: an insulated water tank 1, a heat pump unit 2, an electromagnetic heating atomizing unit 3, a heat storage pool 4, and a water removal structure 5.

[0025] The heat pump unit 2 includes a circulating pump, a heat pump condenser, a heat pump compressor, and a heat pump evaporator. Through heat pump technology, it achieves effective energy saving and high efficiency, improving the unit's operability and social benefits. The heat pump unit 2 is connected to the insulated water tank 1 via water pipes, forming a water circulation heat exchange system. The water in the insulated water tank 1 is heated by heat exchange through the heat pump unit 2 to obtain hot water, which is then stored. The insulated water tank 1 is also equipped with a temperature probe, a water level gauge, and a water inlet for connecting to an external water source. The temperature probe monitors the water temperature in the insulated water tank and coordinates with the heat pump unit's operation control. The water level gauge automatically monitors the water level in the insulated water tank 1 and contacts the water replenishment system for automatic water replenishment control, achieving automated control.

[0026] The electromagnetic heating atomizing unit 3 is located downstream of the insulated water tank 1. The electromagnetic heating atomizing unit 3 heats the hot water provided by the insulated water tank 1 to form atomized gas. In this embodiment, the electromagnetic heating atomizing unit 3 includes two parallel heating cylinders 31. Each heating cylinder 31 draws water from the insulated water tank 1 and heats it. A high-pressure pump pumps water to the heating cylinders 31 for heating, causing the hot water to evaporate and atomize, thus forming atomized gas. The outputs of the two heating cylinders 31 are then combined to output the atomized gas. This atomized gas passes through a corresponding water removal structure 5 and is then supplied to the thermal storage tank 4. The parallel arrangement of the two heating cylinders 31 enhances the heating effect and obtains sufficient and stable atomized gas.

[0027] Figure 3 As shown, the heating barrel 31 includes a vertical cylindrical container 311, a heat-conducting filter material 312 disposed inside the cylindrical container 311, and an electromagnetic heating assembly 313 disposed on the outer periphery of the cylindrical container 311. Hot water provided by the insulated water tank 1 flows from top to bottom through the interior of the cylindrical container 311. Furthermore, an atomizing nozzle is provided at the inlet of the cylindrical container 311 to enhance the heating effect, allowing the hot water to exchange heat with the heat-conducting filter material 312 to generate atomized gas. The electromagnetic heating assembly 313 is energized to heat the hot water and the heat-conducting filter material 312 inside the cylindrical container 311. The heat-conducting filter material 312 is made of stainless steel fiber, which is assembled into the cylindrical container 311 after pressing, providing good heat conduction and atomization effects. Furthermore, a serpentine flow channel is constructed inside the cylindrical container 311, allowing the hot water to move in a serpentine pattern and vaporize, reducing the heating time of the hot water and ensuring even heating of the atomized gas; this also helps to optimize the external structural shape of the cylindrical container 311.

[0028] The thermal storage tank 4 is used to heat the atomized gas output from the electromagnetic heating atomizing unit 3 to form superheated steam. Both the input and output ends of the thermal storage tank 4 are equipped with dehydration structures 5. These structures reduce the moisture content of the steam, achieving two-stage dehydration to improve steam dryness and facilitate heat absorption from the thermal storage tank, resulting in dry, high-temperature, and high-pressure steam suitable for industrial production. This solves the technical problems of relatively high moisture content in steam during existing steam production processes, difficulty in raising steam temperature, and the accumulation of moisture in production equipment and transmission pipelines, causing oxidation and corrosion and affecting service life. It significantly improves steam production efficiency and quality, meeting the requirements of modern industrial production.

[0029] The thermal storage tank 4 includes an insulated outer shell 41 and a high-temperature molten salt 42 disposed within the insulated outer shell 41. The high-temperature molten salt 42 is used to store heat and heat the atomized gas entering the thermal storage tank, thereby generating superheated steam. The high-temperature molten salt 42 is a molten salt phase change thermal storage material, suitable for use in medium- and high-temperature applications, enabling the thermal storage tank 4 to reach a storage temperature of 480-500 degrees Celsius. During manufacturing, heating elements, such as carbon fiber heating tubes, are installed in the high-temperature molten salt 42. These elements can be assembled using a plug-in method, facilitating assembly and replacement and improving manufacturing convenience. The thermal storage tank 4 can fully utilize working intervals to heat and store heat. By employing methods such as peak-shifting electricity consumption, low-cost electric heating storage can be used, significantly reducing system operating costs and improving the practicality and economy of the unit. When the atomized gas flows through the thermal storage tank 4, it absorbs the heat stored in the high-temperature molten salt 42, obtaining high-temperature, high-pressure steam.

[0030] Figure 2 As shown, the water removal structure 5 in this embodiment includes a tank 51 and a water removal material 52 filled inside the tank 51. The water removal material 52 is preferably nano-microcrystalline stone, which is resistant to high temperatures, wear-resistant, and mildew-proof, and is easy to manufacture and implement. The tank 51 is connected to the heat storage tank 4 and / or the electromagnetic heating atomizing unit 3 through a pipe. When the atomized gas or superheated steam passes through the tank 51 and flows through the water removal material 52, the water removal material 52 removes water droplets from the atomized gas or superheated steam through adsorption and separation. The tank 51 is vertically arranged. Atomized gas enters the tank from the top and moves downward before being output. The atomized gas enters the dewatering structure 5 in a spray form, which can effectively increase the contact surface for dewatering and facilitates heat absorption and heating in the heat storage tank 4. Meanwhile, superheated steam enters the tank from the bottom and moves upward before being output. This slows down the steam movement speed, which is beneficial for dewatering and filtration. At the same time, it can ensure stable output pressure and uniform temperature of high-temperature and high-pressure steam. The steam is also dry, which helps to improve the speed and quality of industrial production. It also avoids the oxidation and corrosion of production equipment by residual moisture in the steam, thus extending the service life of the production equipment.

[0031] This invention employs heat pump heating technology combined with a heat storage method, optimizing the unit structure. The heat pump system itself has excellent energy-saving performance; combining it with an insulated water tank achieves energy storage and utilization, resulting in high energy efficiency and even more significant energy savings. The heat storage tank can pre-store heat, fully utilizing working intervals to store heat and achieve peak-shifting electricity use, greatly reducing operating costs. Simultaneously, the hot water provided by the insulated water tank is atomized into atomized gas by an electromagnetic heating atomizer before exchanging heat with the heat storage tank, further enhancing the heating effect and improving thermal efficiency, which helps reduce operating costs. Furthermore, dehydration structures are installed at both the input and output ends of the heat storage tank to reduce the moisture content of the steam, achieving two-stage dehydration and helping to obtain dry, high-pressure steam suitable for industrial production. The entire system has a simple and reliable structure, stable and safe operation, low investment cost, and solves the technical problems existing in boiler combustion steam production, effectively reducing electricity consumption and operating costs, making it suitable for industrial application.

For those skilled in the art, many equivalent improvements and variations can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and variations should all fall within the scope of protection claimed by the present invention.
