Problems solved by technology

[0006] 2) High waste heat grade requirements
Once the user determines the temperature of the water supply, strict requirements are placed on the fluctuation of waste heat supply. Therefore, the use of conventional waste heat recovery and utilization process technology solutions requires the fluctuation of waste heat to be small, because the waste heat recovery system does not have a heat storage device, which limits a large number of Recycling of fluctuating waste heat in line with heating requirements
[0007] 3) The waste heat capacity requirement is high. For a large number of users whose heat supply load is dynamically changing, the conventional waste heat recovery and utilization process technology scheme requires the waste heat capacity to meet the user's maximum heat load, because the waste heat recovery system has no heat storage device. The utilization rate of waste heat is reduced, and the efficiency of the whole waste heat recovery and utilization system is low.
The use of conventional technology solutions will inevitably lead to excessive heat supply capacity and high investment. However, the utilization rate of waste heat is very low, which is extremely unfavorable for the utilization of waste heat.

Description

technical field [0001] The invention relates to a heat recovery, storage and reuse device, in particular to a phase change energy storage device, which belongs to the field of energy saving and environmental protection. Background technique [0002] my country's industrial energy utilization rate is generally low, with an average of less than 27%. For example, 65% of the high-quality waste heat generated in the production process of various industries such as municipal waste incineration, landfill gas, iron and steel, metallurgy, chemical industry, sewage treatment, and power generation The left and right are basically recovered for power generation and industrial steam, but the intermittent, unstable, and low-quality waste heat accounting for more than 85% of the total waste heat has not been fully recovered due to the lack of mature heat storage technology and engineering equipment. The recovery and utilization of waste heat, especially in the process and means of waste heat...
