If it is not utilized, it is undoubtedly a waste of energy
[0004] In the prior art, there are various types of plate-type and heat pipe-type waste heat recovery and exchange devices, but the continuous operation is poor. As the use time goes by, the surface of the heat pipe is covered with dirt, which makes the heat exchange and recovery efficiency significantly lower, and it is not easy to disassemble and wash. Convenient, need to stop the whole heat recovery system for maintenance, high maintenance cost
In addition, because the high-temperature exhaust gas contains a large amount of oil, wax and other components, it cannot be directly recycled, resulting in energy waste.

The invention provides a waste gas heat energy recycling system. The waste gas heat energy recycling system comprises a waste gas heat energy exchange device and a heating device, wherein the waste gas heat exchange device is provided with a first heat exchanger with a first heat pipe, the heating device is provided with a second heat exchanger with a second heat pipe, hot waste gas enters the first heat pipe for heat exchange, water in the first heat pipe is heated and flows into the second heat pipe, water pollution is avoided, fresh normal-temperature air is sucked in from an air inlet of the heating device and makes contact with the second heat pipe to achieve heat exchange, so that heating of the normal-temperature air is achieved, air flowing out of an air outlet of the heating device is heated air and used for secondary utilization of subsequent equipment, and after the second heat pipe realizes heat exchange, water in the second heat pipe is cooled and flows back to the waste gas heat exchange device for reheating, so that cyclic reutilization is formed. Compared with the prior art, the waste gas heat energy recycling system is energy-saving, environment-friendly, high in heat recovery efficiency and good in sustainability.
Description
technical field [0001] The invention relates to the field of an energy recovery and reuse device, in particular to a waste gas heat energy recovery and recycling system. Background technique [0002] Industrial waste heat resources are recyclable resources, especially in the production process of steel, chemical, petroleum, building materials and other industries, there are abundant waste heat resources, making full use of waste heat resources is one of the key factors for enterprises to save energy. Exhaust gas heat energy generally accounts for 17%-70% of its total fuel consumption, and recyclable waste heat resources can effectively improve energy utilization. [0003] In the textile dyeing and finishing industry, the setting machine is the main energy-consuming equipment. Generally, the working temperature of the oven for chemical fibers is above 200°C, and the exhaust gas emission temperature is above 170°C; for cotton fabrics, the temperature is about 170°C, and the ...
