Heating furnace cooling energy medium self-recovery system

Abstract

The invention discloses a self-recovery system for a cooling energy medium of a heating furnace. The system is mainly designed by aiming at the situation that the cooling energy medium is not fully utilized by an existing heating furnace cooling system. According to the self-recovery system for the cooling energy medium of the heating furnace, a first outlet distribution header is connected to an outlet of an in-furnace water beam and is connected with a second outlet distribution header through a pipeline group; a generator set is arranged on the pipeline group; a vapor water mixture in the first outlet distribution header is conveyed to the pipeline group; the vapor water mixture in the pipeline group supplies energy required by the operation of the generator set and is output to the second outlet distribution header through the generator set. According to the self-recovery system for the cooling energy medium of the heating furnace, the vapor water mixture formed by vaporizing saturated water through the in-furnace water beam is converted into the saturated water through the generator set, the saturated water is recycled, and electric energy generated by the generator set can be used for the self-operation of the system.

Description

technical field [0001] The invention relates to a heating furnace cooling energy medium self-recovery system. Background technique [0002] In the field of industrial furnaces, the furnace water beam used to support the heating workpiece is usually cooled by water cooling or vaporization cooling. As the country advocates energy saving and emission reduction, more and more heating furnace water beams are cooled by vaporization cooling. cool down. The vaporization cooling system of the heating furnace produces a large amount of steam. For large-scale joint enterprises, the steam can be recovered uniformly, while more small and medium-sized private enterprises directly discharge the steam into the atmosphere, resulting in a great waste of energy media. Since the heating furnace evaporative cooling system generates a large amount of external steam, it is necessary to continuously replenish new water to the heating furnace steam drum to ensure the safe operation of the evaporati...

Problems solved by technology

This poses a safety hazard during the operation of the heating equipment. Once the power supply stops due to a fault, the vaporization cooling system of the heating furnace will stop working, and the water-cooling medium used for cooling in the system will not be able to flow, and the water-cooling medium will quickly absorb heat and vaporize, resulting in The temperature and pressure rise sharply, thereby destroying the pipes and equipment of the vaporization cooling system, seriously affecting the normal production of the heating furnace
