As shown in Figures 1 to 2, a steam generator includes a burner 1, a combustion chamber 2, a heat exchange tube 3, an inner tank 4, a strong exhaust fan 5, a condenser 6 and a control panel, and the heat exchange tube 3 is set In the liner 4, the strong exhaust fan 5 is connected to one port of the heat exchange tube 3, and the other port of the heat exchange tube 3 is connected to the combustion chamber 2. The steam generator also includes an auxiliary water tank 7, a water level detector 8, and a water temperature detector 9 , pressure detector 10, one-way valve, pressure relief valve 16, gas input pipe 11, cold water input pipe 12 and steam outlet pipe 13, auxiliary water tank 7 is connected to inner tank 4, gas input pipe 11 is connected to burner 1, gas input pipe 11 is provided with a gas control valve 14, the control panel is connected to the gas control valve 14 through wires, the cold water input pipe 12 is connected to the condenser 6, and the condenser 6 is connected to the inner tank 4, and the cold water input pipe 12 is provided with a water control valve 15, and the control panel The water control valve 15 is connected by wires, and the steam outlet pipe 13 communicates with the top of the inner container 4. The control panel is also connected with a water level detector 8, a water temperature detector 9 and a pressure detector 10 by wires, a water level detector 8, a one-way valve, The pressure relief valve 16 and the pressure detector 10 are connected with the auxiliary water tank 7, the water temperature detector 9 is arranged on the outer wall of the liner 4, and the water level detector 8 is arranged in the auxiliary water tank 7. The steam generator has higher thermal efficiency, more environmental protection, more energy saving and safer.

In some embodiments, the steam generator is provided with a flame observation window to observe the combustion of gas, and the steam generator can also be provided with a pressure relief valve 16, which can be connected to the auxiliary water tank 7 to relieve pressure.

The steam outlet pipe 13 of the steam generator is connected to equipment using steam, and is widely used in kitchens, saunas, medicine, textiles, clothing, food manufacturing and other fields.

When using the steam generator, first turn on the power switch, the control panel controls the water control valve 15 and the gas control valve 14 to open, the water flows through the condenser 6 and enters the inner tank 4, when the water level reaches the limited position, the water level detector 8 sends a signal Feedback to the control board, the control board controls the water control valve 15 to close, the gas enters the burner 1, and the gas is ignited by the electronic lighter to burn in the combustion chamber 2. The control board controls the strong exhaust fan 5 to work, and the strong exhaust fan 5 sucks out the high-temperature flue gas generated by the internal gas combustion through the heat exchange tube 3. Since the heat exchange tube 3 is installed in the inner tank 4, the water in the inner tank 4 will be heated Steam is generated, and the steam enters the steam equipment through the steam outlet pipe 13. The heat exchange tubes 3 are multi-curved, and the heat exchange tubes 3 are closely arranged, so that water can be heated faster to form water vapor.

The tail gas produced by gas combustion is high-temperature. In order to improve the efficiency, it needs to be cooled by the condenser 6 when it is discharged. The water in the condenser 6 lowers the temperature of the tail gas while the water temperature rises. When the water flows into the inner tank 4, it already has a certain temperature. , so that the efficiency of steam generation is higher, which not only saves energy, but also improves efficiency.

The continuous generation of water vapor will increase the pressure in the inner tank 4, and the pressure of the discharged steam has certain requirements. When the pressure is slightly higher than the limited pressure, the pressure detector 10 will detect and feed back the signal to the control board, and the control board controls the gas. The control valve 14 and the water control valve 15 are closed to prevent the pressure from continuing to rise. After the pressure drops to a certain value, the control panel controls the gas control valve 14 and the water control valve 15 to open and continue heating. If the pressure detector 10 fails to work normally, the pressure relief valve 16 works to avoid danger.

The generation of water vapor will reduce the water level in the inner tank 4, and when the water level drops to a certain value, it will be detected by the water level detector 8, and the water level detector 8 will feed back the signal to the control board, and the control board controls the water control valve 15 to open until After the water level detector 8 detects that the water level reaches the limited position, the water control valve 15 is closed.

If no water enters in the liner 4 and the water level is lower than the minimum value set by the water level detector 8, the gas control valve 14 and the water control valve 15 will be closed. Under the working condition, the temperature in the inner tank 4 increases rapidly, and the water temperature detector 9 detects abnormal changes and feeds back the signal to the control board, which controls the steam generator to stop working automatically to avoid accidents.

In this way, the steam generator can work automatically after the switch is turned on, and is convenient and safe to use.

The auxiliary water tank 7 is connected with the inner tank 4, and the internal environment of the auxiliary water tank 7 is the same as that of the inner tank 4. The water level detector 8, the one-way valve, the pressure relief valve 16 and the pressure detector 10 are connected with the auxiliary water tank 7, which can ensure the detection The data is accurate, and it can prevent the detection device from being damaged by drastic changes when steam is generated.

When the steam generator is working, the one-way valve is closed, and when the steam generator stops working, the one-way valve is opened under the effect of air pressure, which can prevent the liner 4 from being deformed due to pressure changes.

The steam generator is also equipped with a drain pipe to discharge the dirt.

To sum up, compared with the traditional steam generator, the steam generator described in the utility model has higher thermal efficiency, more environmental protection, more energy saving and safer.

What have been described above are only some embodiments of the present utility model. For those skilled in the art, without departing from the inventive concept of the present utility model, some modifications and improvements can be made, and these all belong to the protection scope of the present utility model.
