At present, the current steam generator completely adopts the heating method of electric energy. In a vessel that can be used for heating, the water in the container is quickly heated to saturated water by using the principle of converting electric energy into heat energy. In this process, the water in normal temperature is directly heated to the temperature of 100 ℃, which requires input of large power A large amount of heat is produced in a short time, which can not be well absorbed and utilized, resulting in the waste of electric energy.

The invention reduces the power of steam generation by preheating and secondary heating, and reduces visit here the heat energy which can not be fully absorbed by excessive energy heat generated in an instant.

The present invention will be further described in detail with reference to the attached drawings and specific embodiments.

The energy-saving heat pump type steam generator of the embodiment is shown in Fig. 1, which includes a water channel and a steam generator 1. The steam generation device is provided with a first water inlet 131, a steam outlet 132 and a steam heating device 12. The energy-saving heat pump type steam generator also includes a heat pump device 2, which comprises a second water inlet 241, a hot water outlet 242, an evaporator 21 and a condenser 23 and a compressor 22, and the hot water outlet 242 is connected to the first water inlet 131.

All water flows through running water.

InIn the heat pump device 2, the refrigerant medium of the evaporator 21 absorbs heat and is transmitted to the condenser 23 through the compressor 22. When the cold water enters the heat pump device 2 from the second water inlet 241 and passes through the condenser 23, the refrigerant medium in the condenser 23 exchanges heat with the water, and then passes through the hot water outlet 242 to the first water inlet 131. After the cold water is heated into steam through the steam heating device 12, the steam flows from the steam outlet 132 to the designated equipment.

Through preheating and secondary heating, the temperature difference is fully utilized to reduce the power consumption of steam generation, prevent the waste of heat generated by excessive heat which can not be absorbed, and achieve the maximum power output, with remarkable energy saving effect.

The water channel is a circular pipe, and the circular pipe is bent and folded, so that the time of water passing through the heat pump device is prolonged, and the water can have a higher temperature when it flows to the steam generator 1.

The heat pump device is provided with a heat insulation device, and the heat insulation device is tin foil. Increasing the heat insulation device can reduce the heat emission, improve the utilization rate of heat and save energy.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the invention, rather than the limitation of the scope of protection of the invention. Although the invention has been described in detail with reference to a better embodiment, those skilled in the art should understand that the technical solution of the invention can be modified or replaced equivalently without departing air to water heat pump from the reality of the technical solution of the invention Quality and scope.
