BAFFLED TANK TYPE SUPERCRITICAL WATER TREATMENT REACTOR WITH SACRIFICIAL LINING

摘要

A baffled tank type supercritical water (SCW) treatment reactor with a sacrificial lining. The reactor comprises a barrel (6) and a catalyst box arranged in the barrel (6), the upper part of the barrel (6) being connected with a top cover (10), and the lower part of the barrel (6) being connected with a spherical seal head (1). The inner side of the barrel (6), the inner side of the spherical seal head (1) and the inner side of the top cover (10) form the inner wall of the reactor. The inner wall of the reactor is provided with a high-temperature resistant and heat insulating coating layer (7). The inner wall of the high-temperature resistant and heat insulating coating layer (7) is provided with a sealing coating layer (8). The inner wall of the sealing coating layer (8) is provided with the sacrificial lining. The combination of the two types of coating layers on the inner wall of the reactor reduces the temperature of the wall of the reactor and meanwhile prevents corrosion on the wall of the reactor. The baffled tank type structure of the reactor can effectively prevent reactor blockage caused by salt deposition. In addition, the catalyst box can be conveniently disassembled such that catalysts are easy to remove and replace. The reactor of the present invention can be widely applied to a harmless treatment and recycling process for high-concentration organic waste water which is difficult to be degraded biochemically.
