[0002] A low-loss steam engine, also known as an energy-saving steam engine or steam generator, is a highly efficient power machine that converts the energy of steam into mechanical work or thermal energy. It uses the heat energy generated by the combustion of fuel (such as natural gas, liquefied petroleum gas, biomass pellets, etc.) to transfer the heat energy to water through a heat exchanger, causing the water to evaporate and produce steam. The steam is then used in various occasions where steam is required, such as cooking, heating, disinfection, etc.

[0003] Heat recovery of steam engines is an important energy-saving measure. It aims to effectively reuse the waste heat generated during the operation of the steam engine to improve energy efficiency and reduce energy consumption. By recycling the waste heat generated by the steam engine, the demand for original energy can be reduced, thereby saving resources, reducing the mining and burning of new energy, and further reducing the emission of harmful gases such as carbon dioxide, nitrogen oxides, and sulfur oxides, which is beneficial to environmental protection. Commonly used methods are waste heat boiler recovery and utilization or condensate closed recovery flash evaporation system.

[0029] The cleaning mechanism 104 includes a mounting frame 110, a rotating screw 111, a moving block 112, a cleaning cylinder 113, a first transmission member 114, a second transmission member 115 and a first motor 116.

In conjunction with the rotation of the cleaning cylinder 113, impurities outside the heat exchange tube 102 are cleaned to ensure the cleanliness of the heat exchange tube 102 and prevent impurities from adhering to the heat exchange tube 102 and affecting the utilization efficiency of waste heat.

[0030] The cleaning cylinder 113 includes a fixed block 120, a mounting cylinder 121, a second motor 122, a rotating shaft 123, a connecting rod 124 and a cleaning outer brush 125.

[0032] See also Figure 2 , Figure 5 and Figure 6According to the above content, a transmission mechanism 15 is set at one end of the heat utilization device 6, and the transmission mechanism 15 includes a shell 301, a rotating rod 302 and a gear 303. The shell 301 is fixedly connected to one end of the water tank 101, the rotating rod 302 is rotatably connected to the inside of the shell 301, the gear 303 is fixedly connected to the outside of the rotating rod 302, and one end of the rotating rod 302 penetrates the water tank 101 and is fixedly connected to the rotating roller 106.

[0033] The steam outlet pipe 4 includes a pipe body 201, a rotating rod 202, a fan blade 203, a guide block 204, a protective pipe 205, a transmission rod 206 and a rotating toothed disc 207.

The top of the transmission rod 206 passes through the tube body 201 and is fixedly connected to the bottom of the rotating rod 202. Therefore, the steam passes through the tube body 201 and is acted upon by the guide block 204, driving the fan blade 203 to rotate, thereby causing the rotating rod 202 to rotate. The transmission of the transmission rod 206 drives the rotating gear plate 207 to rotate. Sealing pads 103 are provided at both ends of the tube body 201.

[0034] The rotating toothed disc 207 is arranged inside the outer shell 301, and the top of the rotating toothed disc 207 is meshed with one side of the gear 303. Therefore, the rotating toothed disc 207 rotates to drive the gear 303 to rotate, and then the rotating rod 302 rotates, so that the rotating roller 106 inside the water tank 101 rotates. The rotating roller 106 rotates through the power of steam, thereby improving the efficiency of waste heat utilization and effectively utilizing the kinetic energy of steam transmission.

[0035] In summary, when the device is in use, the steam equipment body 1 is started to generate a large amount of steam, and the steam is quickly sucked into the interior of the heat utilization device 6 through the vortex air pump 5. The water is heat exchanged through the heat exchange tube 102 inside the heat utilization device 6 to heat the water, and the steam is cooled to form condensed water. The condensed water enters the water storage barrel 11 from the connecting pipe 10, and the excess gas is discharged from the exhaust pipe 12. The condensed water is then input into the interior of the steam equipment body 1 for a second time through the water supply pump 13 and the connecting water pipe 14, so as to realize the reuse of water. The heated water in the water tank 101 is discharged through the drain pipe 8 to meet the industrial living water demand, and is replenished through the water inlet pipe 7.

[0036] The water in the water tank 101 undergoes a heat exchange reaction with the heat exchange tube 102, and the particulate impurities contained in the water will adhere to the heat exchange tube 102, resulting in a decrease in the heat exchange efficiency of the heat exchange tube 102, and a decrease in the waste heat utilization efficiency of the device. The first motor 116 is started to drive the rotating screw 111 to rotate, so that the moving block 112 drives the cleaning cylinder 113 to move, and the second motor 122 inside the cleaning cylinder 113 drives the cleaning outer brush 125 to rotate, so as to remove the impurities and particles adhered to the outside of the heat exchange tube 102, thereby ensuring the cleanliness of the outside of the heat exchange tube 102. The particles are discharged along the drain pipe 8, and then processed by the filtering equipment for industrial or domestic water use, thereby reducing the boiler's sewage discharge and reducing the water treatment cost. At the same time, the cost of the enterprise is reduced due to the reduction in the amount of boiler fuel used.
