Description

Technical Field

[0001] This utility model relates to a steam generating device, and more particularly to an electromagnetic steam generator. Background Technology

[0002] Steam generators are generally used in industrial production, where there are strict requirements for steam temperature and supply volume. How to efficiently utilize steam and reduce energy consumption is the main problem encountered in the practical application of steam generators.

[0003] Application No. 202122535776.1 discloses a variable frequency electromagnetic steam generator, which has an electromagnetic heating coil (4) wound around the bottom of a heating tank (1). The heating tank (1) is equipped with a circulating spraying mechanism (3). The circulating spraying mechanism (3) includes a water inlet pipe (38) installed inside the heating tank (1), with one end of the water inlet pipe (38) away from the heating tank (1) connected to an external water source. The circulating spraying mechanism (3) also includes a water pump (31) installed inside the heating tank (1). The input pipe of the water pump (31) extends to the bottom of the inner cavity of the heating tank (1). The output pipe of the water pump (31) is connected to the inner cavity of the water inlet pipe (38). The right end of the water inlet pipe (38) is fixedly connected to atomizing nozzles (33) arranged at equal intervals. The heating tank (1) is provided with a turbulence mechanism (2). The turbulence mechanism (2) includes a blower (21) installed on the inner wall of the heating tank (1). The air inlet pipe of the blower (21) is located inside the heating tank (1).

[0004] This variable frequency heater mainly uses electromagnetic heating coils to heat the water vapor emitted from multiple atomizing nozzles inside the tank, which is then collected in a steam-water separator. The separated steam is then transported out through the outlet. In this technical solution, the electromagnetic heating coils need to heat the entire tank, resulting in high energy consumption. Furthermore, the steam-water separator is required for water vapor collection and separation, making the structure quite complex.

[0005] Application No. 202322581984.4 discloses a waterless electromagnetic steam generator. This technical solution includes a heat exchange core heated by an electromagnetic heating module. An atomizing nozzle is positioned above the heat exchange core. Atomized water injected through the nozzle is converted into steam and stored after passing through the heat exchange core. However, in this solution, the atomized water is only input from directly above the heat exchange core. During the heating process, the varying amount of atomized water at different locations within the heat exchange core leads to uneven temperatures at different points, resulting in unstable output steam temperatures and difficulty in precise temperature control. Therefore, this design has inherent flaws. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides an electromagnetic steam generator that can accurately control the steam outlet temperature, and has high heating efficiency and saves energy.

[0007] Therefore, the technical solution adopted by this utility model is: an electromagnetic steam generator, including a housing, characterized in that an electromagnetic heating coil is provided inside the housing, multiple water and steam interfaces are provided on the electromagnetic heating coil, the water and steam interfaces are connected to pipelines, electromagnetic valves are provided on the pipelines, and a steam outlet is provided at the output end of the electromagnetic heating coil, and the steam outlet is connected to a steam pipe.

[0008] Preferably, the electromagnetic heating coil includes an upper section coil and a lower section coil, and the water vapor interface is located on the lower section coil.

[0009] Preferably, a steam storage tank is provided between the electromagnetic heating coil and the steam outlet, and an electromagnetic valve is provided at the outlet of the steam storage tank.

[0010] Preferably, the outlet of the steam pipe is connected to a return pipe, and the return pipe is connected to the inlet of the electromagnetic heating coil.

[0011] Preferably, two water vapor inlets are installed on each layer of the coil, and the two water vapor inlets are spaced apart.

[0012] Preferably, the bottom of the electromagnetic heating coil is positioned and installed inside the housing by a bracket.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Multiple water vapor inlets are set on the electromagnetic heating coil, allowing water vapor to enter the electromagnetic heating coil simultaneously from multiple locations to heat it into steam. This ensures that the temperature is consistent at all locations on the electromagnetic heating coil, and the synchronous entry into the heating coil improves evaporation efficiency and reduces energy consumption.

[0015] 2. The electromagnetic heating coil is divided into an upper section and a lower section. Water vapor entering from the lower section evaporates and is pre-stored in the upper section to maintain a stable temperature, which facilitates continuous output.

[0016] 3. There are no requirements for water volume or air pressure, and the steam temperature can be adjusted arbitrarily.

[0017] 4. Install a steam return pipe to recover steam and reduce energy consumption. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 An electromagnetic steam generator, as shown, includes a housing 2, a control cabinet 3 on the side of the housing 2, an electromagnetic heating coil inside the housing 2, multiple steam / water inlets 6 on the electromagnetic heating coil, and external pipelines connected to the steam / water inlets 6. Solenoid valves are installed on the pipelines, and a steam outlet 1 is located at the output end of the electromagnetic heating coil, connected to a steam pipe. In this embodiment, the coil is installed inside the housing and heated electromagnetically. Steam / water inlets are installed on multiple layers of the coil's pipeline, with external pipelines connecting to each inlet. The interconnection and control of each pipeline can be individual, forming a local network or a unified network for overall control. Water / water or other fluid media can be introduced into the pipelines, which are converted into high-temperature steam after being heated by the electromagnetic heating coil. Furthermore, because steam / water enters simultaneously at multiple locations on the coil, not only is the heating efficiency high, but the temperature of the heated steam can also be precisely controlled.

[0023] In a preferred embodiment, the electromagnetic heating coil includes an upper coil 4 and a lower coil 5, with the water vapor inlets 6 all located on the lower coil. This structure ensures that the input water vapor is rapidly heated and vaporized in the lower coil, and the vaporized steam enters the upper coil for precise temperature control, resulting in controllable output steam temperature.

[0024] Specifically, two water vapor inlets 6 are installed on each layer of the coil, and the two water vapor inlets are spaced apart.

[0025] like Figure 2 As shown, in another embodiment, a steam storage tank 9 is provided between the electromagnetic heating coil and the steam outlet 1, and a solenoid valve is provided at the outlet of the steam storage tank 9. Using a steam storage tank for steam storage reduces energy consumption and also allows for precise temperature control.

[0026] In one embodiment, a return pipe is connected to the outlet of the steam pipe, and the return pipe is connected to the inlet 8 of the electromagnetic heating coil. This structure allows for heat recovery of the used steam, which is then reintroduced into the electromagnetic heating coil, saving energy.

[0027] Specifically, in terms of the installation structure, the electromagnetic heating coil is positioned and installed inside the housing 2 by a bracket 7 at the bottom.

[0028] This invention features multiple steam inlets on an electromagnetic heating coil, allowing steam to enter simultaneously from multiple locations and heat it into steam. This ensures a consistent temperature throughout the coil and improves evaporation efficiency while reducing energy consumption. The electromagnetic heating coil consists of an upper and lower section. Steam entering from the lower section evaporates and is then stored in the upper section to maintain a stable temperature for continuous output. The overall structure is simple, requiring no specific water volume or pressure, and the steam temperature can be precisely controlled and adjusted. A steam return pipe is incorporated to recover steam, further reducing energy consumption.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
