[0028] This embodiment provides a gas-liquid mixed material vaporization system 10, please refer to Figure 1 , which includes an evaporator 11, a jet mixer 12 and a material mixer 13.

[0029] The upper part of the evaporator 11 has a liquid phase inlet 111 for feeding liquid phase materials. The jet mixer 12 has a gas phase inlet 121 for feeding gas phase materials. The inside of the evaporator 11 is connected to the jet mixer 12, so that the liquid phase materials in the evaporator 11 can enter the jet mixer 12, and the gas phase materials can atomize the liquid phase materials in the jet mixer 12 to obtain a mixture.

[0030] The inlet of the material mixer 13 is connected to the outlet of the jet mixer 12, so that the mixture can enter the material mixer 13 from the jet mixer 12 for mixing. The top of the evaporator 11 has a gas outlet 112, and the material mixer 13 is installed at the lower part of the evaporator 11. The outlet end of the material mixer 13 is located inside the evaporator 11, so that the mixture discharged from the material mixer 13 can enter the evaporator 11 for heating and vaporization and can be discharged from the gas outlet 112. Optionally, the material mixer 13 and the evaporator 11 are an integrated structure.

[0031] In the gas-liquid mixed material vaporization system 10 of the embodiment of the present application, the gas phase material atomizes the liquid phase material in the action of the jet mixer 12, so that the gas phase material and the liquid phase material are fully mixed, and the mixture enters the material mixer 13 for mixing again, and then enters the evaporator 11 for heating and vaporization, so that the gas phase material and the liquid phase material are fully and evenly mixed. In addition, the above-mentioned implementation scheme of the present embodiment adopts a design combining the evaporator 11 with the jet mixer 12 and the material mixer 13, replacing the scheme in the prior art that requires an additional preheater 14 to achieve the same effect. In the prior art, the preheater 14 is required to heat the mixed mixed material, and then pass it into the evaporator 11 for evaporation. The above-mentioned scheme of the present embodiment not only reduces the number of equipment used and saves equipment space, but also reduces the amount of pipeline 131, installation costs and other supporting auxiliary facilities, greatly reducing the production and operation costs.

[0032] Please refer to Figure 2 For example, the material mixer 13 has a plurality of connected pipes 131, and the plurality of pipes 131 are arranged in an S shape. The S-shaped arranged pipes 131 increase the contact area of ​​the medium, so that the mixture is heated more fully in the pipes 131 of the material mixer 13. Furthermore, the internal channel 1311 inside the pipe 131 is spiral, so that the mixture can be heated more evenly.

[0033] Exemplarily, the outlet end of the material mixer 13 is provided with a discharge device 132, and the discharge device 132 includes at least one discharge pipe 1321, and the tube wall of the discharge pipe 1321 is provided with a plurality of discharge holes 1322. It can help the gas to be discharged, and at the same time, it can further absorb the liquid phase material. Exemplarily, two discharge pipes 1321 are provided, and the two discharge pipes 1321 are arranged in a V shape. In other embodiments, the discharge pipe 1321 can also be arranged in three or four, and one end of the multiple discharge pipes 1321 is connected together and maintained in communication, and two adjacent discharge pipes 1321 are arranged in a V shape.

[0034] Furthermore, in some embodiments, the gas-liquid mixed material vaporization system 10 further includes a preheater 14, the outlet of the preheater 14 is connected to the liquid phase inlet 111 of the evaporator 11, and the inlet of the preheater 14 is used to supply liquid phase material, and the liquid phase material can enter the evaporator 11 after being preheated by the preheater 14. Among them, the liquid phase material is fed into the preheater 14 through the first pipeline 161, and the feed amount of the first pipeline 161 is controlled by the flow rate of the liquid phase material and the liquid level of the evaporator 11. When the liquid level of the evaporator 11 is too high, the feed amount of the preheater 14 can be reduced to reduce the liquid level of the evaporator 11. When the liquid level is too low, the feed amount of the first pipeline 161 can be increased to increase the liquid level of the evaporator 11.

[0035] The gas-liquid mixed material vaporization system 10 is further provided with a first heat source supply device 151 and a first heat source recovery device 152. Both the first heat source supply device 151 and the first heat source recovery device 152 are connected to the preheater 14. The first heat source supply device 151 is used to supply a low-temperature heat source to the preheater 14 to heat the liquid-phase material in the preheater 14, and the first heat source recovery device 152 is used to recover the heat source in the preheater 14. The first heat source supply device 151 supplies a low-temperature heat source to the preheater 14 to heat the liquid-phase material in the preheater 14, and the low-temperature heat source after cooling is recovered by the first heat source recovery device 152.

[0036] The gas-liquid mixed material vaporization system 10 is also provided with a second heat source supply device 153 and a second heat source recovery device 154. The second heat source supply device 153 and the second heat source recovery device 154 are both connected to the evaporator 11. The second heat source supply device 153 is used to supply heat source to the evaporator 11 to heat the liquid phase material in the evaporator 11, and the second heat source recovery device 154 is used to recover the heat source after cooling of the evaporator 11. Among them, the low-temperature heat source temperature of the second heat source supply device 153 is higher than the low-temperature heat source temperature of the first heat source supply device 151. The present application can utilize the low-temperature waste heat source to realize low-temperature vaporization of the liquid phase material mixed with the gas phase material in the evaporator 11, effectively utilizing the low-temperature heat source, improving the waste heat utilization, and reducing energy consumption.

[0037] The working principle of the gas-liquid mixed material vaporization system 10 of the present application embodiment is as follows:

[0038] According to the minimum ratio of gas-phase material to liquid-phase material in the reaction operation, the liquid-phase material is supplied to the preheater 14 through the first pipeline 161, and the liquid-phase material is preheated by the preheater 14 and supplied to the evaporator 11 from the liquid-phase inlet 111 of the evaporator 11; the gas-phase material is supplied to the jet mixer 12, and the liquid-phase material from the evaporator 11 is atomized by the jet mixer 12 to obtain a mixture, and the mixture enters the material mixer 13 from the jet mixer 12 for mixing, and then enters the evaporator 11 for heating and vaporization, and is discharged from the gas outlet 112 of the evaporator 11 after vaporization.
