A heat storage device based on waste heat flue gas heat utilization

Abstract

The invention provides a heat storage device based on heat utilization of waste hot smoke. The heat storage device comprises a heat storage cavity, a plurality of heat storage preformed parts accommodated in the heat storage cavity, a waste hot smoke inlet channel, a waste hot smoke discharge channel, a cold air inlet channel and a cold air discharge channel. Both the waste hot smoke inlet channel and the cold air discharge channel are communicated with one side of the heat storage cavity. Both the waste hot smoke discharge channel and the cold air inlet channel are communicated with the other side of the heat storage cavity. The multiple heat storage preformed parts are arranged at intervals, and each heat storage preformed part can rotate around the axis of the heat storage preformed part. According to the heat storage device based on heat utilization of the waste hot smoke, the waste hot smoke can be utilized effectively, so that the energy utilization efficiency is improved; at the same time, the preformed parts and an assembling technology are adopted, industrial production can be conducted by a large margin, and the production efficiency is improved; a little of grapheme is mixed, so that the heat exchange efficiency of the heat storage device can be improved, and large application value is achieved.

Description

technical field [0001] The invention relates to a heat storage material, in particular to a heat storage device based on heat utilization of waste heat flue gas. Background technique [0002] Energy is the material basis for the survival and development of human society. At present, the energy consumed in my country mainly comes from non-renewable mineral energy such as coal, oil, and natural gas. With the further development of our country's society and economy, the demand for energy continues to grow. Building a stable, economical, clean and secure energy supply system is facing major challenges. A large number of high-energy-consuming enterprises such as iron and steel plants, cement plants, and power plants in my country consume a large amount of energy every year and generate a large amount of waste heat. Due to current technical limitations, a large amount of heat energy is not fully utilized and is directly discharged into the atmosphere, resulting in energy waste. ....

AI Technical Summary

Problems solved by technology

Although there are many heat storage devices currently studied, most of them use hot water or heat transfer oil liquid phase as the heat exchange medium, and there are few reports on heat storage devices that study the utilization of waste heat and flue gas in industrial applications.

[0006] At present, in many factories, such as cement plants, smelting plants, ceramic factories, etc., the recovery of waste heat and flue gas is mainly for drying materials. A large amount of heat can only be discharged into the atmosphere, resulting in a large amount of waste of heat energy, and the efficiency of heat utilization is extremely low
