Description

Technical Field

[0001] This utility model relates to the technical field of steam generating devices, specifically a medium-frequency induction steam generator. Background Technology

[0002] In the fields of industrial production and commercial services, steam generators are important heat energy conversion equipment, and their performance directly affects production efficiency and energy consumption. Traditional steam generators are mainly divided into three categories: electric heating type, gas type and induction heating type. Among them, induction heating technology has received widespread attention in recent years due to its characteristics of fast heating speed and high thermal efficiency.

[0003] A search revealed a patent, CN220152708U, which discloses an electromagnetic induction heating steam generator with an instant heating structure. This generator includes: a housing, the bottom of which is fixedly connected to the top of a base; the interior of the housing is fixedly connected to the bottom of a motor; the output end of the motor is fixedly connected to the end of a rotating shaft; the upper left side of the housing is fixedly connected to the end of a water inlet pipe; a water inlet valve is installed inside the water inlet pipe; and the upper right side of the housing is fixedly connected to the end of an exhaust pipe. In use, the inner wall of the housing can be scraped off using a scraper, removing scale buildup and preventing energy waste caused by scale absorbing heat during electromagnetic coil heating.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes the generation of steam by heating water inside the casing with an electromagnetic heating coil at the bottom of the casing. However, in reality, when there is a large amount of water inside the casing, the efficiency of generating steam through the electromagnetic heating coil is slow, and the overall device is bulky, making it inconvenient for installation in actual working conditions. Therefore, there is an urgent need in the art to improve the steam generator in order to overcome the shortcomings of the prior art. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a medium-frequency induction steam generator, which improves the efficiency of the steam generator while having a smaller overall size, making it suitable for installation under different working conditions.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a medium-frequency induction steam generator, comprising a nozzle, a vortex blower and a high-pressure water pump, wherein an atomizing pipe is provided inside the nozzle, an induction coil for heating is provided on the side of the nozzle, and a plurality of atomizing ports are provided on the side of the atomizing pipe.

[0008] The nozzle is used for directional steam injection. Power lines are provided at both ends of the induction coil. An air supply pipe is provided between the vortex blower and the nozzle. The vortex blower is used to generate high-pressure gas. A water supply pipe is fixedly installed between the atomizing pipe and the high-pressure water pump. The high-pressure water pump is used to transport water.

[0009] Preferably, a flow divider is fixedly installed at one end of the nozzle, the air supply pipe is fixedly installed on one side of the flow divider, and a plurality of air blowing pipes are fixedly installed on the side of the flow divider away from the air supply pipe.

[0011] Preferably, the induction coil is spiral-shaped and is coiled around the side of the nozzle.

[0012] Preferably, the atomizing pipe is cylindrical and is adapted to the spray nozzle.

[0013] Preferably, the nozzle is a Laval nozzle, and one end of the nozzle is flared.

[0014] Preferably, there are several blower tubes, and the atomizing pipe is located between several blower tubes.

[0015] Preferably, one end of the water supply pipe extends into the spray pipe and is fixedly installed on the side of the atomizing pipe, and the atomizing pipe and the spray pipe are concentric.

[0016] To address the shortcomings of existing technologies, this utility model provides a medium-frequency induction steam generator, overcoming these deficiencies. The beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, the nozzle is heated by energizing the induction coil, and the high-pressure water pump delivers water to the atomizing pipe. The water is atomized through several atomizing ports and sprayed onto the inner wall of the nozzle. The water vaporizes and is discharged through several atomizing ports. The vortex blower generates high-pressure gas and delivers it to the nozzle through the air supply pipe to blow out the steam, thereby improving the efficiency of the steam generator. At the same time, the overall device is small in size and suitable for installation under different working conditions.

[0018] 2. In this utility model, high-pressure gas is transported to the distribution hood through the air supply pipe and discharged through several air blowing pipes.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figures 1-4 A medium-frequency induction steam generator includes a nozzle 1, a vortex blower 2, and a high-pressure water pump 3. The nozzle 1 is equipped with an atomizing pipe 6, and an induction coil 7 for heating is provided on the side of the nozzle 1. Several atomizing ports 8 are opened on the side of the atomizing pipe 6. The nozzle 1 is used for directional steam injection. Power lines 12 are provided at both ends of the induction coil 7. An air supply pipe 4 is provided between the vortex blower 2 and the nozzle 1. The vortex blower 2 is used to generate high-pressure gas. A water supply pipe 5 is fixedly installed between the atomizing pipe 6 and the high-pressure water pump 3. The high-pressure water pump 3 is used to transport water.

[0030] The specific implementation method in this embodiment is as follows: When the steam generator is needed, the nozzle 1 is installed in the designated position using existing fastening devices. Alternating current is supplied through the power cord 12. When the alternating current passes through the induction coil 7, an alternating magnetic field is generated around it. The nozzle 1 is made of conductive material, and the alternating magnetic field induces eddy currents (i.e., circulating currents) inside the nozzle 1. Under the action of the metal resistor, the eddy currents convert electrical energy into heat energy, causing the nozzle 1 to heat up. The heating depth can be precisely controlled by the alternating magnetic field in the mid-frequency band (500Hz-20kHz). The higher the frequency, the more concentrated the vortex becomes on the surface of nozzle 1. The lower the frequency, the greater the heating depth. When the temperature of nozzle 1 reaches the vaporization temperature, the vortex blower 2 and the high-pressure water pump 3 are turned on. The high-pressure water pump 3 delivers water to the atomization pipe 6. The water is atomized through several atomization ports 8 and sprayed onto the inner wall of nozzle 1. The water vaporizes and is discharged through several atomization ports 8. The vortex blower 2 generates high-pressure gas and delivers it to nozzle 1 through the air supply pipe 4 to blow out the steam, thereby improving the efficiency of the steam generator. At the same time, the overall device is small in size and suitable for installation under different working conditions.

[0033] In this embodiment, the high-pressure gas is delivered to the diversion hood 9 through the air supply pipe 4 and discharged through several air blowing pipes 10. The air blowing pipes 10 are staggered with the nozzle 1, so that the air blowing pipes 10 will not be impacted by the high-pressure gas, thus improving the effect of steam ejection.
