Description
Technical Field
[0001] The present invention relates to the technical field of environmental protection recycling and utilization, and in particular to a factory waste heat recovery and reuse system. Background Art
[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. The boiler consists of two major parts: pot and furnace. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and also has a small number of applications in industrial production. A boiler that produces steam is called a steam boiler, often referred to as a boiler, and is mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises.
[0003] When a boiler is used in a factory to transport hot water through factory pipes, the factory pipes will emit a large amount of heat and steam. If the heat and steam cannot be recovered and reused, it will cause a waste of resources. To this end, we propose a factory waste heat recovery and utilization system. Summary of the invention
