[0036] Working principle: The water tank 22 is located at the top of the steam generator 1. The water in it can use regenerated water to achieve environmental protection. It is connected with the heating cavity at the bottom of the steam generator 1 through a pipeline. When the water in the heating cavity is heated and vaporized, the water in the water tank 22 is replenished to the heating cavity under the action of gravity, realizing a continuous steam generation process. The generated steam is transmitted to the air outlet pipe 23 from the water tank 22. The heat in the air outlet pipe 23 is transmitted to the water inlet pipe 2 19 through the heat exchanger 12, achieving the purpose of preheating regenerated water. At the same time, through the heat preservation and insulation of the heat insulation sleeve 1 1, it enters the heat preservation tank 9 for temporary storage. The unused hot gas in the air outlet pipe 23 can be transmitted to the purification tank 14 through the water outlet pipe 2 20 and heated by the heating rod 2 21, achieving the effect of utilizing residual heat, which can improve the purification efficiency of regenerated water. At the same time, the water vapor in the water tank 22 also flows into the purification tank 14, achieving the effect of recycling. At the same time, the regenerated water is preheated by the steam, which can make the regenerated water evenly heated and the heat evenly distributed in the regenerated water, avoiding local overheating.

[0037] When the reclaimed water flows from the inlet pipe one 201, the flow rate is controlled by the valve one 204 to optimize the appropriate flow rate to allow the suspended matter in the water to have sufficient time to contact the filter medium, while the water pump 202 transmits the reclaimed water from the bottom of the purification tank 14 to the top of the purification tank 14 and flows out from the inlet pipe two 19, when passing through the activated carbon 207, the reclaimed water can have sufficient contact time with the activated carbon 207 to allow the organic matter and part of the heavy metal ions and other impurities in the water to be better adsorbed, when passing through the filter screen 206, the reclaimed water can have sufficient residence time on the surface of the filter membrane to allow the small impurities to be effectively intercepted in the filter membrane, and finally after passing through the sterilizer 205, the oxidation reaction occurs with the bacteria, viruses and microorganisms in the water to destroy the cell membrane and protein structure of the microorganisms, thereby effectively killing the microorganisms, so that after the treatment of the activated carbon 207, the filter screen 206 and the precision disinfection device sterilizer 205, most of the impurities and pollutants in the water are removed, the calcium, magnesium metal ions and other scale-forming substances in the water are reduced, thereby reducing the scale generation in the preheating process, improving the heat transfer efficiency and prolonging the service life of the heating equipment.
