Coking plant water gradient utilization water-saving process
The invention relates to a water-saving process for gradient utilization of water in a coking plant, which belongs to the technical field of coking, and specifically comprises the following steps: raw water enters a water pretreatment device for pretreatment, the pretreated raw water enters a desalting water device for desalting, the desalted raw water enters a dry quenching boiler to generate medium-pressure steam, the medium-pressure steam enters a steam using device, and the steam using device is used for using steam. Condensed water generated by the steam using device is recycled to the condensed water recycling device, the condensed water recycling device returns the condensed water to the coke dry quenching boiler to be utilized, concentrated water generated by the desalting water device enters the high-density pool hardness removal device to be subjected to hardness removal, and waste water generated by the ammonia distilling device and the chemical device enters the sewage treatment device to be treated. Concentrated water generated by the sewage treatment device enters the evaporation salt extraction device to produce finished salt, reclaimed water generated by the sewage treatment device, the concentrated water subjected to hardness removal, part of raw water and wastewater generated by the dry quenching boiler enter the circulating water device to provide cooling water for cooling equipment, water can be effectively saved, and wastewater discharge is effectively reduced.
本发明涉及一种焦化厂水梯级利用节水工艺，属于焦化技术领域，具体包括原水进入水预处理装置进行预处理，经预处理后的原水进入除盐水装置进行除盐，经除盐后的原水进入干熄焦锅炉产生中压蒸汽，中压蒸汽进入蒸汽使用设备，蒸汽使用设备产生的凝结水回收至凝结水回收装置，凝结水回收装置将凝结水返回至干熄焦锅炉进行利用，除盐水装置产生的浓水进入高密池除硬装置进行除硬，蒸氨装置和化工装置产生的废水进入污水处理装置进行处理，污水处理装置产生的浓水进入蒸发提盐装置生产成品盐，污水处理装置产生的中水、除硬后的浓水及部分原水、干熄焦锅炉产生的废水进入循环水装置为各冷却设备提供冷却水，本发明能够有效节约用水，有效降低废水排放。
