Description

Technical Field

[0001] The utility model relates to a steam generator, in particular to an air energy variable frequency electromagnetic high-efficiency steam generator. Background Art

[0002] Steam generators have been widely used in industrial production, food processing, heating and other fields. Electric heating, gas or oil are usually used to generate steam. However, these traditional heating methods have many shortcomings. Although electric heating steam generators are easy to operate, they are relatively inefficient and have high energy consumption. The main reason is that there is a large energy loss in the process of converting electrical energy into thermal energy by the electric heating element, and the heating speed is slow. In addition, although gas and oil heating methods can produce high-temperature steam, there are environmental issues. The exhaust gas emitted pollutes the environment and the operating cost is high.

[0003] Air energy technology is a new type of energy-saving and environmentally friendly technology. It heats water by absorbing heat from the air. It has the advantages of high energy efficiency, low operating cost and good environmental performance. However, there are obvious limitations in relying solely on air energy heat pumps to generate steam. The working principle of air energy heat pumps determines that their output temperature is greatly affected by the ambient temperature and usually cannot reach the high temperature required for steam generation. Especially in winter or low temperature environments, the efficiency of air energy heat pumps will be significantly reduced, making it difficult to meet the demand for high-temperature steam. Therefore, it is necessary to make further improvements to it. Utility Model Content

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below with reference to the accompanying drawings. An air-energy variable frequency electromagnetic high-efficiency steam generator comprises an autoclave 1, the autoclave 1 is hollow inside to form a heating chamber 2, an isolation sleeve 3 is arranged inside the isolation sleeve 3, an electromagnetic heating coil 4 is installed inside the isolation sleeve 3 to heat the isolation sleeve 3, the isolation sleeve 3 heats the cold water in the heating chamber 2 to generate high-temperature steam, and the electromagnetic heating coil 4 is connected to an electromagnetic drive circuit;

[0023] The autoclave 1 is also connected with a water inlet pipe 10 connected to a heat pump water tank 5. The heat pump water tank 5 is provided with a heat exchange coil 6 connected to a heat pump host 7. The heat pump host 7 heats the water in the heat pump water tank 5 by using the heat exchange coil 6.

[0024] The heat pump water tank 5 is also connected to a water inlet pipe 8, which passes through the center of the electromagnetic heating coil 4 and is connected to a water supply valve 9;

[0025] The autoclave 1 is provided with a steam supply pipe 12 connected to a gas-using device.

[0026] In one of the embodiments: the autoclave 1 is also connected to a steam overpressure protection valve 13 and a steam pressure relief valve 14 .

[0027] In one of the embodiments: the isolation sleeve 3 is made of ferromagnetic material, and its outer wall is connected to the heating chamber 2.

[0028] In one embodiment, the autoclave 1 is also connected to a steam pressure gauge 15 and a steam drain valve 16 .

[0029] In one embodiment, the water supply valve 9 is connected to a water network.

[0030] Working principle: The variable frequency electromagnetic high-efficiency steam generator with air energy heating of the present invention cleverly combines air energy heat pump and variable frequency electromagnetic heating technology, and realizes efficient and rapid generation of high-temperature and high-pressure steam through the coordinated work of two different heating mechanisms. Its working principle is as follows:

[0031] 1. Air-to-heat pump preheating water: The heat pump main unit 7 absorbs heat from the air through the heat exchange coil 6 and transfers the heat to the water in the heat pump water tank 5. Due to the efficient heat transfer mechanism of the air-to-heat pump, the water is quickly heated to a higher temperature. The preheated water enters the heating chamber 2 of the autoclave 1 through the water inlet pipe 10.

[0032] 2. Further heating by electromagnetic heating: An isolation sleeve 3 is provided in the heating chamber 2 inside the autoclave 1, and an electromagnetic heating coil 4 is installed inside the isolation sleeve 3. The electromagnetic heating coil 4 is connected to the electromagnetic drive circuit and driven by a variable frequency power supply to generate an alternating magnetic field. The alternating magnetic field acts on the isolation sleeve 3, causing the ferromagnetic material inside to generate eddy currents and hysteresis losses, thereby generating heat. The isolation sleeve 3 quickly heats the water around it, and the water in the heating chamber 2 rises rapidly under the heating effect of the isolation sleeve 3, and finally produces high-temperature and high-pressure steam.

[0033] 3. Steam supply and pressure control: The generated high-temperature steam is transported to the gas-using equipment through the steam supply pipe 12. In order to ensure the safety of the equipment and the stable supply of steam, the autoclave 1 is equipped with a steam overpressure protection valve 13 and a steam pressure relief valve 14. When the steam pressure is too high, these valves will automatically open to release excess pressure to prevent damage to the equipment. At the same time, the autoclave 1 is also equipped with a steam pressure gauge 15 and a steam drain valve 16 to monitor and adjust the steam pressure in real time to ensure that the system operates within a safe pressure range.

[0034] 4. Water replenishment system: In order to ensure the continuous operation of the system, the heat pump water tank 5 is connected to the center of the electromagnetic heating coil 4 through the water inlet pipe 8 and connected to the water replenishment valve 9. The water replenishment valve 9 is connected to the water network. When the system needs to replenish water, cold water is added through the water replenishment valve 9 to ensure that there is always enough water in the autoclave 1 for heating. Among them, the water inlet pipe 8 passes through the center of the electromagnetic heating coil 4 and is connected to the water replenishment valve 9. Therefore, when the water inlet pipe is taking in water, it also has the function of dissipating heat for the electromagnetic heating coil, reducing the temperature of the electromagnetic heating coil when it is working, thereby ensuring that it can work stably and efficiently for a long time:

[0035] In summary, the present invention combines air energy heat pump and variable frequency electromagnetic heating technology, uses air energy heat pump to preheat water, increases the initial water temperature, and then further rapidly heats water to the high temperature and high pressure required for steam through variable frequency electromagnetic heating technology. This design not only improves energy utilization efficiency and reduces operating costs, but also ensures a stable supply of high-temperature steam. It is suitable for a variety of industrial and life application scenarios, so it can be widely promoted and used.

The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
