[0038] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] like Figure 1 and Figure 2 As shown, the present invention provides an explosion-proof electromagnetic heating device for petroleum and natural gas, including a heat exchanger 100 and a control cabinet 200. The heat exchanger 100 includes a cylindrical outer shell 160, and an electromagnetic coil 140 and a plurality of circular tubes 130 are provided inside the outer shell 160. Specifically, the electromagnetic coil 140 is arranged in the middle part of the outer shell 160, and the two are coaxially arranged. These circular tubes 130 are evenly distributed around the electromagnetic coil 140, and the circular tubes 130 are made of corrosion-resistant steel to adapt to the transportation of crude oil and natural gas. The outer shell 160 of the control cabinet 200 adopts an explosion-proof outer shell 160. The control cabinet 200 includes a switch and a control module. The switch controls the opening and closing of the electromagnetic coil 140, and the electromagnetic coil 140 is connected to an AC power supply. Preferably, in this embodiment, the insulation layer of the electromagnetic coil 140 is a mica insulation layer, which is temperature-resistant up to 400°C and has good insulation durability. When alternating current passes through electromagnetic coil 140, it generates a high-frequency alternating magnetic field. This field produces eddy currents within the metal tube, which intensify the motion of metal molecules, generating heat. This heat is transferred through the tube's walls to the fluid (such as oil or natural gas) within the device, achieving heating. Simultaneously, the exterior of heat exchanger 100 exchanges heat with the surrounding environment, dissipating heat to maintain the temperature within the heat exchanger 100 within a safe range. By adjusting the power and frequency of the electromagnetic heating system, the heating rate and temperature of the fluid (crude oil or natural gas) can be controlled to meet different process requirements.

[0040] Specifically, a temperature sensor 110 is provided at the top of the housing 160. The temperature sensor 110 is used to detect the temperature of the crude oil or natural gas in the circular tube 130. A pressure sensor 120 is provided at the bottom of the housing 160. The pressure sensor 120 is used to detect the pressure of the crude oil or natural gas in the circular tube 130. The temperature sensor 110 and the pressure sensor 120 are respectively electrically connected to the control module, and the control module controls the voltage of the power supply. The temperature sensor 110 monitors the temperature of the fluid in the device in real time and transmits the temperature signal to the controller. The control module adjusts the power of the electromagnetic heating system according to the preset temperature value to keep the fluid temperature within the set range. When the fluid temperature exceeds the set upper limit, the control module will reduce the power of the electromagnetic heating system or even stop heating to prevent overheating. When the fluid temperature is lower than the set lower limit, the control module will increase the power of the electromagnetic heating system to speed up the heating speed.

[0041] Pressure sensor 120 monitors the pressure of the fluid within the device in real time and transmits the pressure signal to the control module. When the pressure exceeds a set safety value, the control module triggers the safety valve to open, releasing some fluid to reduce the pressure. Simultaneously, the control module adjusts the flow rate and velocity of the fluid based on pressure fluctuations to maintain the pressure within a safe range.

[0042] In this embodiment, the control module adopts an Infineon IGBT module.

[0043] In this embodiment, flanges 161 are provided at each end of the housing 160. Flanges 161 are fixedly connected to the cover plate 170 via fasteners 180. Preferably, fasteners 180 are bolts and nuts. The cover plate 170 has multiple through-holes for the circular tubes 130 to pass through. A T-shaped bracket 150 is provided at the bottom of the housing 160 to support the entire heat exchanger 100.

[0044] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
