A waste heat energy heat exchange system based on a phase change heat storage tank

Abstract

The invention discloses a waste heat energy and heat exchange system based on a phase change heat storage box. The waste heat energy and heat exchange system based on the phase change heat storage box comprises a phase change heat storage box component and a movable water storage box component, wherein the phase change heat storage box component comprises a phase change heat storage box, and a water hot water box in a shape formed by two homocentric squares different in area, a grating heat exchanger, a heat exchange air sac and phase change medium paraffin, which are arranged in an inner cavity of the phase change heat storage box, the movable water storage box component comprises a box body, a heat source water inlet and a heat source water outlet are formed in the box body, an idler wheel is arranged at the lower end of the box body, a water outlet of the grating heat exchanger is connected with the heat source water inlet of the movable water storage box component through an electric draining pump, the heat source water outlet of the movable water storage box component is connected with a mini boosting pump, and the mini boosting pump is connected with a heat supply device. The waste heat energy and heat exchange system based on the phase change heat storage box can substantially improve heat storage capacity of a heat storage device, uses material phase change to achieve energy transfer, has the advantages of being large in heat exchange area, large in heat storage quantity and high in heat exchange efficiency, can simultaneously use air heat and water heat, fully recycles and reuses waste water heat, can achieve continuous heat storage and release functions, and is simple in structure and suitable for waste heat recycle of fluid waste heat.

Description

technical field [0001] The invention relates to the technical field of waste heat energy recovery and reuse, in particular to a phase-change heat storage box and a waste heat recovery and reuse system thereof. Background technique [0002] With the development of society, energy issues have received more and more attention, and fossil energy is becoming increasingly scarce. Energy has become an important factor restricting the development of the world economy. Scientists say that knowing new energy and using it correctly means knowing the road to the future. According to the existing social and economic development, there are resources and energy problems, so while ensuring comfort and health requirements, how to effectively and reasonably 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 energy and use the pha...

AI Technical Summary

Problems solved by technology

The use of phase change heat storage materials for energy storage can fully recover waste heat energy, and use the phase change of substances to realize energy conversion. However, the existing phase change energy storage generally has long charging and discharging time, single function, and the heat exchange area and storage capacity are limited. Disadvantages such as low heat
