Description

Technical Field

[0001] This utility model relates to the technical field of methanol evaporation bubbling vaporization device, specifically a methanol evaporation bubbling vaporization device. Background Technology

[0002] Methanol, as an important chemical raw material and clean energy carrier, has a wide range of applications in chemical synthesis, fuel cells and other fields. In these applications, it is often necessary to efficiently and stably convert liquid methanol into gaseous methanol vapor. Bubbling vaporization technology, as a common phase change heat transfer method, is used in the methanol vaporization process because of its large gas-liquid contact area and high heat and mass transfer efficiency.

[0003] Existing methanol bubbling vaporization units mostly use electric heaters to directly heat the tank. The heating area is concentrated, which can easily lead to local overheating, causing methanol decomposition, coking, and carbonization. This not only affects the vaporization quality but also clogs the pipelines, damaging the long-term stability and lifespan of the equipment. Although there are improved solutions such as jacketed heating, their heat exchange area is limited, their efficiency is low, and it is difficult to ensure the uniformity of the temperature field. Utility Model Content

[0004] The purpose of this invention is to provide a methanol evaporation bubbling vaporization device, which solves the problem that existing methanol bubbling vaporization devices mostly use electric heaters to directly heat the tank, resulting in concentrated heating areas that are prone to local overheating, causing methanol decomposition, coking, and carbonization. This not only affects the vaporization quality but also clogs the pipelines, damaging the long-term stability and lifespan of the equipment. Although there are improved solutions such as jacketed heating, their heat exchange area is limited, their efficiency is low, and it is difficult to ensure the uniformity of the temperature field.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a methanol evaporation bubbling vaporization device, including a vaporizer body. The upper surface of the vaporizer body is equipped with a liquid inlet, a carrier gas inlet and a steam inlet. The outer surface of the vaporizer body is equipped with a methanol steam outlet, a liquid outlet and a carrier gas outlet. A cavity is opened inside the vaporizer body. A heating mechanism is provided on one side of the vaporizer body. The heating end of the heating mechanism is installed inside the cavity.

[0006] Furthermore, the heating mechanism includes an insulation box, a pump is installed on one side of the insulation box, the input end of the pump is connected to the inside of the insulation box, and a spiral tube is fixedly installed on the output end of the pump. The spiral tube is fixedly installed inside the cavity and fits against the inner wall of the cavity.

[0007] Furthermore, the outlet end of the spiral tube extends to the outer surface of the vaporizer body, and a connecting pipe is fixedly installed at the outlet end of the spiral tube.

[0008] Furthermore, a heater is fixedly installed on the upper surface of the insulation box, the input end of the heater is connected to one end of the connecting pipe, and the output end of the heater is connected to the interior of the insulation box.

[0009] Furthermore, an insulation sleeve is fitted onto the outer surface of the connecting pipe.

[0010] Furthermore, the insulation sleeve is made of rock wool.

[0011] This utility model has the following beneficial effects: (1) When the heating mechanism of this utility model is started, the heater starts to work and heats the heat transfer medium in the heat preservation box to the set temperature. The circulation pump works and drives the high-temperature heat transfer medium to flow. Then, it enters the circulation heating and bubbling vaporization stage. The high-temperature heat transfer medium flows into the spiral tube under the drive of the pump. The spiral tube is installed in the cavity. Its heat is efficiently transferred to methanol through the tube wall, so that its temperature rises rapidly to the optimal vaporization temperature. After the heat exchange is completed, the heat transfer medium with reduced temperature flows out from the outlet of the spiral tube and returns to the heater through the connecting pipe for reheating, forming a closed and continuously heated circulation loop. This realizes large-area indirect heating of liquid methanol. The spiral tube increases the heat exchange area, so that the methanol is heated evenly. It effectively avoids methanol decomposition, coking and carbonization problems caused by excessive local temperature, and ensures vaporization quality and long-term stable operation of the equipment.

[0012] (2) By setting up the heat insulation jacket, this utility model can reduce the large amount of heat loss during the circulation of hot water, thereby directly reducing the energy consumption of the heater and improving the thermal efficiency and economy of the whole device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0017] Please see Figures 1-4 As shown, this utility model is a methanol evaporation bubbling vaporization device, including a vaporizer body 1. A liquid inlet 101 and a carrier gas inlet 102 are installed on the upper surface of the vaporizer body 1. A methanol vapor outlet 104, a liquid outlet 105 and a carrier gas outlet 106 are installed on the outer surface of the vaporizer body 1. A cavity 103 is opened inside the vaporizer body 1. A heating mechanism 2 is provided on one side of the vaporizer body 1. The heating end of the heating mechanism 2 is installed inside the cavity 103. Carrier gas is introduced into the bottom of the vaporizer body 1 through the carrier gas inlet 102. During the upward process, the carrier gas passes through the heated liquid methanol, forming a large number of bubbles. At the interface between the bubbles and the liquid, the liquid methanol evaporates rapidly and enters the interior of the bubbles, turning into methanol vapor. Finally, the product is output. The gas flow rich in methanol vapor rises to the top of the vaporizer and is stably output through the methanol vapor outlet 104 to supply downstream equipment such as fuel cells and reactors. The liquid outlet 105 can be used to drain residual liquid during equipment maintenance. In this embodiment, the carrier gas outlet 106 should be understood as a spare port or drain port. During normal bubbling vaporization operation, this outlet is closed to ensure that all carrier gas can participate in the bubbling process and be sent out from the methanol vapor outlet 104.

[0018] The heating mechanism 2 includes an insulation box 201, a pump 202 is installed on one side of the insulation box 201, the input end of the pump 202 is connected to the inside of the insulation box 201, and a spiral tube 203 is fixedly installed on the output end of the pump 202. The spiral tube 203 is fixedly installed inside the cavity 103 and fits against the inner wall of the cavity 103. The outlet end of the spiral tube 203 extends to the outer surface of the vaporizer body 1, and a connecting pipe 204 is fixedly installed at the outlet end of the spiral tube 203. A heater 205 is fixedly installed on the upper surface of the heat preservation box 201. The input end of the heater 205 is connected to one end of the connecting pipe 204, and the output end of the heater 205 is connected to the inside of the heat preservation box 201. An insulation sleeve 206 is fitted onto the outer surface of the connecting pipe 204; Heating mechanism 2 is activated, and heater 205 starts working, heating the heat transfer medium in insulation box 201 to the set temperature. Circulation pump 202 works, driving the high-temperature heat transfer medium to flow. Subsequently, it enters the circulation heating and bubbling vaporization stage. Driven by pump 202, the high-temperature heat transfer medium flows into spiral tube 203. Spiral tube 203 is installed in cavity 103, and its heat is efficiently transferred to methanol through the tube wall, causing its temperature to rise rapidly to the optimal vaporization temperature. After heat exchange is completed, the cooled heat transfer medium flows out from the outlet of spiral tube 203 and returns to heater 205 through connecting pipe 204 for reheating, forming a closed, continuously heated circulation loop.

[0019] The insulation jacket 206 is made of rock wool; The rock wool insulation sleeve 206 wrapped around the connecting pipe 204 can effectively reduce heat loss in the pipeline and improve energy utilization efficiency.

[0020] Working Principle: In operation, liquid methanol first enters the vaporizer body 1 through the liquid inlet 101 until the liquid level reaches a predetermined height. Then, the heating mechanism 2 is activated, and the heater 205 begins to work, heating the heat transfer medium in the insulation box 201 to the set temperature. The circulation pump 202 operates, driving the high-temperature heat transfer medium to flow. Subsequently, the circulation heating and bubbling vaporization stage begins. Driven by the pump 202, the high-temperature heat transfer medium flows into the spiral tube 203. The spiral tube 203 is installed in the cavity 103, and its heat is efficiently transferred to the methanol through the tube wall, causing its temperature to rise rapidly to the optimal vaporization temperature. After heat exchange is completed, the cooled heat transfer medium flows out from the outlet of the spiral tube 203 and returns to the heater 205 through the connecting pipe 204 for reheating, forming a closed, continuously heated circulation loop. During this process, the heat transfer medium wrapped in the connecting pipe 204... The rock wool insulation jacket 206 outside the pipeline can effectively reduce heat loss and improve energy utilization efficiency. At the same time, the carrier gas is introduced into the bottom of the vaporizer body 1 through the carrier gas inlet 102. During the rising process, the carrier gas passes through the heated liquid methanol and forms a large number of bubbles. At the interface between the bubbles and the liquid, the liquid methanol evaporates rapidly and enters the interior of the bubbles, turning into methanol vapor. Finally, the product output is completed. The gas flow rich in methanol vapor rises to the top of the vaporizer and is stably output through the methanol vapor outlet 104 to supply downstream equipment such as fuel cells and reactors. The liquid outlet 105 can be used to drain residual liquid during equipment maintenance. In this embodiment, the carrier gas outlet 106 should be understood as a spare port or drain port. During normal bubbling vaporization operation, this outlet is in a closed state to ensure that the carrier gas can participate in the bubbling process and be sent out from the methanol vapor outlet 104.
