Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] as attached figure 1 , 2 As shown in and 3, a waste heat energy recovery system coupled with a large phase-change thermal storage tank includes a large phase-change thermal storage tank assembly and a waste heat energy recovery assembly; the heat source inlet port of the large phase-change thermal storage tank assembly is connected to a waste heat source, The heat supply outlets of the phase change heat storage large tank assembly are respectively connected to direct heating and indirect heating equipment. The direct heating equipment is a heating room fan, and the indirect heating equipment is a waste heat recovery component.

[0022] The large phase-change thermal storage tank assembly includes a large phase-change thermal storage tank 1, in which a drum-type waste water tank 3 and an outer phase-change medium paraffin layer are sequentially arranged in the ...

Abstract

The invention provides a coupling type waste heat energy recovering system for a large phase-change heat storage cylinder. The system comprises a large phase-change heat storing cylinder assembly and a waste heat energy recovering assembly; the hot source inlet end of the large phase-change heat storing cylinder assembly is connected with a waste heat water source, and the heat supply outlet end of the large phase-change heat storing cylinder assembly is respectively connected with a direct heating device and an indirect heating device. The system is simple in structure; the heat of waste water is fully recovered and recycled; therefore, the function of fast storing heat and radiating heat can be achieved; the system is suitable for recycling of afterheat from the waste heat of liquid.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery and reuse, in particular to a waste heat recovery and reuse system coupled with a large phase-change heat storage tank. Background technique [0002] With the development of society, more and more attention has been paid to energy issues, fossil energy has become increasingly scarce, and energy has become an important factor restricting the development of the world economy. Scientists say that knowing new energy sources and using them correctly means knowing the way to the future. According to the existing social and economic development, there are resource and energy problems. Therefore, while ensuring comfort and health requirements, how to effectively and rationally allocate and utilize resources and reduce conventional energy consumption has become a problem that people have to face. The use of phase change heat storage materials for energy storage can fully recover waste heat ene...
