[0019] Embodiment: As shown in FIGS. 1-4, the steam generator comprises a tank body 1, a heater 2 and a flow control assembly 3, the inside of the tank body 1 is provided with a flow guide pipe 4, the heater 2 is installed at the top of the tank body 1, the flow guide pipe 4 is installed in the inside of the tank body 1, the flow control assembly 3 is connected with the flow guide pipe 4, and the flow control assembly 3 is used for controlling the liquid flow in the flow guide pipe 4. Figure 1 Figure 3 The steam generator comprises a tank body 1, a heater 2 and a flow control assembly 3, the inside of the tank body 1 is provided with a flow guide pipe 4, the heater 2 is installed at the top of the tank body 1, the flow guide pipe 4 is installed in the inside of the tank body 1, the flow control assembly 3 is connected with the flow guide pipe 4, and the flow control assembly 3 is used for controlling the liquid flow in the flow guide pipe 4.
[0020] The flow control assembly 3 includes a low-pressure pump 31 and a high-pressure pump 32, which jointly act on different parts of the flow guide pipe 4 to achieve effective management of the liquid flow. The flow guide pipe 4 includes a low-pressure section 41 and a high-pressure section 42. The low-pressure section 41 is a preheating section, and the high-pressure section 42 is a high-temperature vaporization section. The inlet of the low-pressure section 41 is connected to the low-pressure pump 31, the outlet of the low-pressure section 41 is connected to the inlet of the high-pressure pump 32, and the outlet of the high-pressure pump 32 is connected to the inlet of the high-pressure section 42. The high-pressure pump 32 is used to control the water storage volume of the high-pressure section 42 to be within thirty liters, which can ensure that one ton to 1.5 tons of water should be evaporated in one hour.
[0021] The low-pressure pump 31 is used to provide raw materials, mainly for providing initial raw material input to the system. Through the low-pressure inlet connecting plate 411 connected to the low-pressure section inlet, the low-pressure pump can stably deliver a certain amount of liquid into the low-pressure section 41 of the flow guide pipe. The pressure at this stage is low, which is suitable for preliminary processing.
[0022] The high-pressure pump 32 is used for pressure flow control. After preliminary pressurization, the liquid flows from the low-pressure section to the high-pressure section, and the pressure needs to be further increased. At this time, the high-pressure pump takes over the task and applies greater pressure to the liquid to achieve the required working state. The high-pressure pump is connected to the high-pressure section inlet connecting plate 421 to ensure accurate pressure regulation.
[0023] The heater 2 is installed on the top of the tank body 1 for heating the tank body 1.

[0025] The outlet of the low-pressure section 41 is fixedly connected with the low-pressure outlet connecting plate 412 outside the tank body 1, and the low-pressure outlet connecting plate 412 is fixedly connected with the high-pressure pump 32 through a pipeline.
[0026] The inlet of the high-pressure section 42 is fixedly connected with the high-pressure section inlet connecting plate 421, which is arranged outside the tank body 1, and the high-pressure section inlet connecting plate 421 is fixedly connected with the high-pressure pump 32.
[0027] The low-pressure section 41 and the high-pressure section 42 are communicated through the high-pressure pump 32. When starting the steam generator, the low-pressure pump 31 first extracts the external water source and injects it into the low-pressure section 41 of the flow guide pipe through the low-pressure inlet connecting plate 411. As the liquid moves along the flow guide pipe, it is sent into the high-pressure pump 32 after reaching the low-pressure outlet connecting plate 412. In this process, the heater 2 has started to operate, gradually increasing the temperature in the tank until the boiling point, promoting the evaporation of the liquid into steam.
[0028] Then, under the action of the high-pressure pump, the formed steam continues to advance to the high-pressure section 42, and finally, the finished steam is discharged through the high-pressure section outlet connecting plate 422 into the next process.
[0029] The outlet of the high-pressure section 42 is fixedly connected with a high-pressure section outlet connecting plate 422, and the high-pressure section outlet connecting plate 422 is used for connecting a connecting pipe of the next process.
