Description

Technical Field

[0001] This utility model relates to the field of waste heat utilization and environmental protection technology, and in particular to a waste heat utilization and environmental protection equipment. Background Technology

[0002] Waste heat is energy that is not utilized in energy utilization equipment under certain economic and technical conditions; it is excess and waste energy. Waste heat recovery and utilization is an important way to improve economic efficiency and save fuel. There are many ways to recover and utilize waste heat, but there are three main ways: direct utilization of waste heat, waste heat power generation, and comprehensive utilization of waste heat. In power plants, the main way to utilize waste heat is waste heat power generation.

[0003] In thermal power plants, the heat energy generated by coal combustion heats water to produce high-temperature, high-pressure steam. The steam drives the turbine to rotate, and the turbine drives the generator rotor to rotate, ultimately generating electricity. When existing combustion furnaces are in use, the flue gas produced during fuel combustion is discharged. Due to the large amount of particulate matter inside, it will pollute the environment. In addition, the flue gas contains a lot of waste heat. If it is discharged directly, it will result in energy waste and reduce heat utilization efficiency. Therefore, we propose an environmentally friendly waste heat utilization device. Utility Model Content
