[0002] The wastewater produced in the process of coal gasification and coking contains a large amount of volatile acid gases (CO2, H2S, etc.), free ammonia, fixed ammonia (ammonium salts), phenolic substances, etc., the purification treatment and recovery of coal chemical wastewater For utilization, the acid gas and ammonia dissolved in water must first be removed before entering the subsequent dephenolization and biochemical treatment process. The content of inorganic salts in coal chemical industry wastewater is high, and it is easy to scale in the process of acid gas removal and cause reboiler The heat transfer coefficient is reduced, and even the heat transfer pipe is blocked. The superheated steam consumes a lot and consumes a lot of energy. The complex structure of the heating reboiler results in increased investment and operating costs, and the existing processing equipment is too slow in heating, wasting people's time. A lot of time, reducing the processing quality
