A steam management system for coal chemical industry

Abstract

The utility model embodiment provides a kind of steam management system of coal chemical industry, comprising: coal gasification black water energy recovery system, first steam pressure boosting and temperature raising system, second steam pressure boosting and temperature raising system and steam pipe network control equipment.Coal gasification black water energy recovery system includes: the soft water heat exchanger of forming soft water circulation closed loop, flash tank and circulating water pump.Wherein, coal gasification black water energy recovery system exchanges heat with coal gasification black water and carries out flash distillation, and low temperature low pressure steam pipe network is supplied with steam;First steam pressure boosting and temperature raising system is compressed and heated to low temperature low pressure steam and obtains medium temperature medium pressure steam, and medium temperature medium pressure steam pipe network is supplied with steam;Second steam pressure boosting and temperature raising system is compressed and heated to medium temperature medium pressure steam, and high temperature high pressure steam pipe network is supplied with steam.Therefore, the quantity of high temperature high pressure steam of boiler production is effectively reduced, resource waste is reduced, energy utilization of steam pipe network is greatly optimized, and the energy saving and emission reduction of coal chemical industry is realized.
