Abstract

The invention discloses a Texaco gasifier grey water treatment and recovery system which comprises a Ca<2+> / Mg<2+> precipitation tank connected with a black water settling tank water outlet, a filtering machine feeding tank connected with a black water settling tank, a crude slag filtering machine connected with the filtering machine feeding tank, a first drainage pump, a first precipitate collecting tank and a grey water tank which are connected with the Ca<2+> / Mg<2+> precipitation tank, a precipitate filtering machine connected with the first precipitate collecting tank, a MAP reaction precipitation tank connected with the grey water tank, a second precipitate collecting tank and a clear water tank which are connected with the MAP reaction precipitation tank, a MAP recovery device connected with the second precipitate collecting tank, and a shock cooling water inlet pump connected with a clear water tank overflow weir water outlet. The system is simple in process and easy to operate, is a novel grey water treatment system capable of quickly and efficiently removing Ca<2+>, Mg<2+> and NH4<+>-N in grey water, and prolongs the equipment overhaul cycle and production cycle by more than 6 months.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to a Texaco gasifier ash water treatment and resource recovery system. Background technique [0002] Due to the increasing shortage of petroleum resources worldwide, my country's coal chemical industry has become a strategic focus of economic development in recent years, especially to produce clean energy (such as hydrogen, methane, methanol, etc.) or replace petrochemical products (such as ethylene raw materials, polypropylene raw materials, The development momentum of the new coal chemical industry based on dimethyl ether, etc.) is strong. Among them, Texaco (GE) coal-water slurry gasification technology is one of the more successful coal gasification technologies at home and abroad, and has a history of more than 30 years in my country. However, the coal gasification process has environmental protection problems such as large water consumption and large wa...
