Abstract
The invention provides an efficient recovery and conversion system for infrared radiation waste heat of a high-temperature steel billet, and belongs to the field of waste heat recovery and utilization. The problem that an existing waste heat recovery system cannot effectively and conveniently recover infrared radiation energy in the metallurgical process is solved. The device comprises a blackbody radiation receiver, a selective radiation emitter, an evanescent wave waveguide transmission sheet and a photovoltaic cell, the blackbody radiation receiver is located over a steel billet, and the upper portion of the blackbody radiation receiver is connected with the selective radiation emitter. The upper portion of the selective radiation emitter is connected with a photovoltaic cell through an evanescent wave waveguide transmission sheet. The device is mainly used for recycling and converting infrared radiation waste heat of high-temperature steel billets.
Description
technical field [0001] The invention belongs to the field of waste heat recovery and utilization, and in particular relates to a high-efficiency recovery conversion system for high-temperature billet infrared radiation waste heat. Background technique [0002] In recent years, extensive research has been conducted on the recovery and utilization of high-quality waste heat from blast furnace slag sensible heat, steelmaking slag, coke oven raw gas, and pellet waste heat in iron and steel enterprises. At present, the waste heat power generation in the iron and steel industry mainly has the following three methods. One is to use the waste heat of the coking and sintering process to generate superheated steam for power generation; the other is to use the waste heat of the flue gas in the steelmaking and rolling process to generate saturated steam for power generation; Use hot water from blast furnace slag to generate electricity. It can be seen that the current research directio...
