Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a gas-liquid mixer with an oil bath heating spiral core structure. Background Art

[0002] Gas-liquid mixers are primarily used to mix gases with compatible liquids. They are widely used in sewage treatment, fresh-frozen fish preservation, aquaculture oxygen supply, river purification, medical treatment, and the health industry.

[0003] Traditional gas-liquid mixers often have some defects when used. The gas-liquid mixer cannot stir the gas and liquid, and the gas dissolution efficiency is low; the bubbles dissolved by the gas-liquid mixer are large and have a short residence time in the liquid, so the gas and liquid cannot be fully mixed. In addition, existing gas-liquid mixers generally have problems such as uneven heating, difficulty in temperature control, and unsatisfactory mixing effect. In certain chemical production processes, in order to ensure the uniformity of the gas-liquid reaction, it is usually necessary to heat the liquid in the mixer and keep it within a certain temperature range. However, traditional heating methods (such as electric heating, steam heating, etc.) are prone to local overheating or insufficient heating, resulting in poor mixing effect and high product rejection rate, which seriously affects production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the deficiencies in the above-mentioned prior art and provide a gas-liquid mixer with an oil bath heating spiral core structure, aiming to solve the problems of uneven heating, difficult temperature control and low mixing efficiency in the existing gas-liquid mixing equipment.

[0006] One end of the spiral vortex core is fixedly connected to the gas-liquid mixing pipeline, and the end of the gas-liquid mixing pipeline away from the spiral vortex core is fixed with a gas-liquid tee pipe. The two ends of the gas-liquid tee pipe that are not connected to the gas-liquid mixing pipeline are respectively the liquid inlet and the gas inlet. The other end of the spiral vortex core is fixedly connected to the mixed gas outlet.

[0007] The oil bath heating structure includes a heat-conducting oil sleeve, which is sleeved on the outer periphery of the shell. The heat-conducting oil sleeve has an upper and a lower opening on both sides. The two openings are the oil bath inlet and the oil bath outlet, respectively, one of which is close to the liquid inlet.

[0008] Preferably, the surface of the spiral core can be designed to be smooth or textured as required.

[0009] Preferably, a gas distribution orifice plate is provided at one end of the spiral core close to the air inlet, and a plurality of small holes are evenly distributed on the gas distribution orifice plate, and the diameter of the small holes is 0.5-2 mm.

[0010] Preferably, the shell, the spiral core and the gas-liquid mixing pipeline are coaxial.

[0011] Preferably, the shell is made of stainless steel, and each part is welded by argon arc welding.

[0012] Preferably, the oil bath heating structure is connected to an external constant temperature heating system.

[0013] Compared with the prior art, the present invention has the following advantages:

[0026] like Figure 1-2 shows a gas-liquid mixer with an oil bath heating spiral vortex core structure, comprising a shell 1, an oil bath heating structure 2, a spiral vortex core 10, a gas-liquid mixing pipeline 6, a liquid inlet 9, an air inlet 7, and a mixed gas outlet 4. A spiral vortex core 10 is provided inside the shell 1 and penetrates the interior of the device longitudinally. The spiral vortex core 10 can achieve efficient gas-liquid mixing in a relatively short time, and is used to increase the gas-liquid contact area and mixing efficiency. The shell 1 of the mixer is preferably made of stainless steel, which has strong corrosion resistance and can withstand a certain pressure. The various parts are welded by argon arc welding, which can reduce oxidation during welding, ensure smooth welds, and prevent gas or liquid leakage.

[0027] The spiral core 10 is made of high temperature resistant material and runs through the interior of the device in the longitudinal direction. The spiral core introduces gas into the liquid by rotating and evenly distributes it, thereby increasing the gas-liquid contact area and improving the mixing effect. The surface of the spiral core (10) can be designed to be smooth or textured as required.

[0028] In this embodiment, one end of the spiral vortex core 10 is fixedly connected to the gas-liquid mixing pipeline 6, and a gas-liquid three-way pipe 12 is fixed to the end of the gas-liquid mixing pipeline 6 away from the spiral vortex core 10. The two ends of the gas-liquid three-way pipe 12 that are not connected to the gas-liquid mixing pipeline 6 are the liquid inlet 9 and the air inlet 7 respectively, and the other end of the spiral vortex core 10 is fixedly connected to the mixed gas outlet 4.

[0029] In this embodiment, the oil bath heating structure 2 includes a heat-conducting oil sleeve 8, which is sleeved on the outer periphery of the shell 1. The heat-conducting oil sleeve 8 has an upper and lower opening on both sides. The two openings are close to the liquid inlet 9, one is the oil bath inlet 3, and the other is the oil bath outlet 5. The heat-conducting oil circulates in the heat-conducting oil sleeve 8 through the oil bath inlet and outlet. The oil bath inlet 3 and the oil bath outlet 5 are externally connected to a constant temperature oil bath heating device to ensure that the heat-conducting oil circulates at a specified temperature and makes the temperature in the mixer uniform.

[0030] It should be noted that a gas distribution orifice plate 11 is provided at one end of the spiral core 10 near the air inlet 7. A plurality of small holes are evenly distributed on the gas distribution orifice plate 11, and the diameter of the small holes is 0.5-2 mm. Through the gas distribution orifice plate 11, the gas can be evenly dispersed into the liquid to form stable small bubbles, further improving the uniformity of the gas-liquid mixing. The gas distribution orifice plate 11 is made of 316L stainless steel to enhance its corrosion resistance and antioxidant capacity. The gas distribution orifice plate 11 is fixed to the bottom of the spiral core. The position of the orifice plate needs to be aligned with the direction of the spiral core to ensure that the gas rises along the spiral path after entering the liquid, thereby increasing the gas-liquid contact area.

[0031] In this embodiment, the housing 1 , the spiral core 10 , and the gas-liquid mixing pipeline 6 are coaxial.

[0032] During use, the heat transfer oil is heated by an external heater and then enters the oil bath heating structure 2, flowing through the heat transfer oil sleeve 8 to achieve uniform heating of the shell 1. The oil bath heating method keeps the temperature inside the gas-liquid mixer constant, avoiding the temperature unevenness caused by traditional heating methods.

[0033] The gas enters the mixer from the air inlet 7, is first evenly dispersed through the gas distribution orifice 11, and then gradually flows downward along the guidance of the spiral core 10. Due to the rotation of the spiral core and the special structural design, the liquid in the mixer undergoes strong turbulence and shearing when flowing through the spiral core 11, so that the gas and liquid phases can be mixed more evenly, achieving an ideal mixing effect.

[0034] The gas-liquid mixer with an oil-bath heated spiral core structure of the present invention has the advantages of simple structure, good mixing effect, low energy consumption, and long service life. It is suitable for gas-liquid mixing needs in the chemical, environmental protection, petrochemical and other fields. By adopting the spiral core design, the present invention effectively improves the gas-liquid mixing efficiency, reduces the energy loss of traditional mixers, and extends the service life of the equipment, with broad market application prospects.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
