Embodiment Construction
[0067] The equipment that the embodiment of the present invention adopts is all known setting equipment.
[0068] a. Sewage water and exhaust steam recovery system and process flow of decarburization furnace dephosphorization furnace vaporization cooling system in steelmaking workshop
[0069] a.1 Process flow of high-pressure sewage and external steam recovery system produced by 3 steam drums of decarburization furnace
[0070] like figure 1 As shown, a set of external steam recovery device is used to recover the high-pressure sewage and external steam generated by the three steam drums of the decarburization furnace. The external steam recovery device consists of 3 sets of flash evaporation devices 4 and 3 sets of absorption power devices 1 and 1 A set of external exhaust steam recovery device body 2 and a set of mixed water recovery device 3 are composed;
[0071] The recovery system is divided into two branches, and the connection sequence is as follows: ①Steam drum-flas...

The invention relates to the technical field of energy recycling in iron and steel enterprises, in particular to a steelmaking converter evaporation cooling dynamic energy recovery system and a technological process. Steam for heating a deaerator of a traditional evaporation cooling device is exhaust steam; an evaporation cooling system is a high (low) pressure sewage drainage system; and the steam emission of the exhaust steam for heating a high-pressure deaerator in a steelmaking workshop influences the production safety, damages the surrounding environment, and wastes the water resource. The steelmaking converter evaporation cooling dynamic energy recovery system consists of a decarburization furnace and dephosphorization furnace evaporation cooling system drained sewage and exhausted steam recovery system in the steelmaking workshop, a heat accumulator high-pressure drained water recovery system of a decarburization furnace steam dome and a dephosphorization furnace steam dome in the steelmaking workshop, a steam dome examined and repaired drained sewage recovery system of a decarburization furnace and dephosphorization furnace evaporation cooling system in the steelmaking workshop, and a decarburization furnace and dephosphorization furnace high-pressure thermal deaerator exhausted steam recovery system in a steelmaking converter. The steelmaking converter evaporation cooling dynamic energy recovery system realizes the recycling for exhausted steam of all the systems, the recycling for high-pressure drained sewage and the recycling for examined and repaired drained water.
Description
technical field [0001] The invention relates to the technical field of energy recovery and utilization in iron and steel enterprises, in particular to a steelmaking converter [0002] Chemical cooling dynamic energy recovery system and process flow. Background technique [0003] The steam used for heating the deaerator of the vaporization cooling device of the original iron and steel enterprise exhausts steam; the high (low) pressure sewage system of the vaporization cooling system; It causes damage to the surrounding environment of the steelmaking plant and wastes a lot of water resources. Therefore, it is urgent to recycle the steam discharged from the deaerator of the converter vaporization cooling system, the steam discharged from the expansion vessel for regular blowdown, the sewage, and the steam used for heating the high-pressure deaerator in the steelmaking workshop. Contents of the invention [0004] The purpose of the present invention is to make use of the wat...
