The input end of the hollow tubular heating component 3 is used to connect to the mixed liquid source to be separated. The hollow tubular heating component 3 is used to preheat the mixed liquid passing through the hollow tubular heating component 3 before entering the separator body 2.

[0030] Specifically, if Figure 3 As shown, in this embodiment, the hollow tubular heating component 3 is divided into an input connector 301 , a double-layer heating tube body 302 , an output connector 303 and a heating rod 304 .

[0031] The double-layer heating pipe body 302 includes an inner tube portion 3021 and an outer tube portion 3022. The interior of the inner tube portion 3021 forms a channel for the mixed liquid to pass through. An annular limit stop 30211 is convexly provided in the middle of the outer peripheral surface of the inner tube portion 3021. An external thread is provided on the outer peripheral surface of the inner tube portion 3021 on one side of the annular limit stop 30211. The outer tube portion 3022 is located on the other side of the annular limit stop 30211 and is connected to the annular limit stop 30211. The outer tube portion 3022 is covered on the outside of the inner tube portion 3021 on the other side of the annular limit stop 30211. A heat exchange liquid holding space 3023 is formed between the inner wall of the outer tube portion 3022 and the outer peripheral surface of the inner tube portion 3021 on the other side of the annular limit stop 30211. The heat exchange liquid holding space 3023 is filled with heat exchange liquid. In this embodiment, the inner tube portion 3021, the outer tube portion 3022, and the annular stop 30211 are all integrally formed and made of metal material with good thermal conductivity. In this embodiment, the heat exchange fluid can be a mixture of high-purity water + antifreeze, high-purity water + silica gel, or high-purity water + stearic acid.

[0032] The input connector 301 is hollow and communicates with the passageway within the inner tube 3021 for the mixed liquid to pass through. The input connector 301 serves as the input end of the hollow tubular heating assembly 3, connecting to the source of the mixed liquid to be separated.

The output connector 303 also serves as the output end of the hollow tubular heating assembly 3, connecting to the mixed liquid input of the separator body 2. The internal threads of the output connector 303 are also used to connect to the mixed liquid input of the separator body 2, making installation and connection easy.

[0034] Specifically, in this embodiment, a filling port is provided on the outer tube portion 3022, communicating with the heat exchange fluid storage space 3023. A filling port plug 305 is provided on the filling port to seal the filling port. In this embodiment, the filling port plug 305 is made of rubber and has a wide top and narrow bottom structure, which reduces the possibility of loosening and falling.

[0037] The spiral flow channel inner core 203 is divided into a top cover portion 2031 and a spiral inner core portion 2032 connected together. The spiral inner core portion 2032 of the spiral flow channel inner core 203 is spiral-shaped. The outer sleeve 204 is sleeved on the outer side of the spiral inner core portion 2032 of the spiral flow channel inner core 203. A spiral flow channel for the mixed liquid to pass through is formed between the inner side of the outer sleeve 204 and the spiral inner core portion 2032 of the spiral flow channel inner core 203. A mixed liquid through hole 20311 connected to the spiral flow channel is opened on the top cover portion 2031. The upper part of the outer sleeve 204 and the top cover portion 2031 are respectively connected to the fixed sleeve 202, and the lower part of the input pipe 201 is also connected to the fixed sleeve. The outer sleeve 202 is connected, and an outer sleeve through hole for the outer sleeve 204 to pass through is opened on the top of the separator tank body 1. The lower part of the outer sleeve 204 penetrates into the inner cavity of the separator tank body 1 from the outer sleeve through hole. The outer side surface of the outer sleeve 204 is fixed to the separator tank body 1 by welding. The outer peripheral surface of the upper part of the input connecting pipe 201 is provided with an external thread. The upper part of the input connecting pipe 201 is connected as the mixed liquid input end of the separator main body 2 with the output end of the hollow tubular heating component 3, that is, the output joint 303. The lower end of the whole formed by the outer sleeve 204 and the spiral inner core part 2032 of the spiral flow channel inner core 203 serves as the mixed liquid output end of the separator main body 2.

[0038] Specifically, in this embodiment, a filter 205 is installed between the outer side surface of the lower portion of the outer sleeve 204 within the inner cavity of the separator tank 1 and the inner wall of the separator tank 1. The filter 205 is located below the gas outlet 101 and above the liquid outlet 102. In this embodiment, the filter 205 is made of wire mesh and secured using existing technology. When the gas within the separator tank 1 flows upward and contacts the filter 205, some of the residual liquid carried by the gas flow collects on the filter 205, forming droplets that drip under the action of gravity, further ensuring effective oil and gas separation.

[0039] Specifically, in this embodiment, the fixing sleeve 202 is made of rubber. It has openings at its upper and lower ends and a hollow interior. An annular intermediate stop 2021 is protruding inward from the center of the inner wall of the fixing sleeve 202. The annular intermediate stop 2021 and the upper opening of the fixing sleeve 202 are used together to position the lower portion of the inlet pipe 201. The annular intermediate stop 2021 and the lower opening of the fixing sleeve 202 are used together to position the upper portion of the outer sleeve 204 and the top cover 2031, facilitating assembly and disassembly. The rubber material of the fixing sleeve 202 is elastic, prevents leakage, and provides cushioning capabilities.

[0040] Working principle:

[0041] By setting up the hollow tubular heating component 3, the mixed liquid passing through the hollow tubular heating component 3 can be preheated before entering the separator body 2, which can effectively reduce the viscosity of the liquid, enhance the fluidity of the liquid, have an anti-freeze effect and prevent pipeline blockage; when in use, the heat exchange liquid is heated by the heating rod 304, and then heat is exchanged with the inner tube 3021. The inner tube 3021 can uniformly heat the mixed liquid to be separated passing through it; the heating rod 304 is only in contact with the heat exchange liquid, which can effectively prevent the heating rod 304 from rusting and avoid the danger of flammable liquid in the mixed liquid to be separated being electrified. By setting up the separator body 2 including the input pipe 201, the fixed sleeve 202, the spiral flow channel inner core 203, and the outer sleeve 204, the mixed liquid from the hollow tubular heating component 3 can be accelerated while the flow rate remains unchanged due to the sudden reduction of the inlet cross-section when entering the spiral flow channel through the mixed liquid through hole 20311. The spiral flow channel part can make the liquid rotate and flow, disperse the impact on the wall of the separator tank body 1, and realize gas-liquid separation in the separator tank body 1, reducing the problem of local stress concentration, thereby improving the separation efficiency and service life.
