The invention relates to a novel transpiring wall reactor for supercritical
sewage treatment. The reactor mainly comprises an upper end
flange, a cylinder, a lower end
flange, a top connector, a burner
assembly and transpiring walls, wherein the upper end
flange, the cylinder and the lower end flange are fixedly installed, and a sealed space is formed; the top connector is connected with the burner
assembly, then is fixedly installed in the center of the upper end flange and is provided with a fuel inlet; a liquid outlet is formed in the lower end flange. The novel transpiring wall reactor is characterized in that the cylinder is provided with multiple
layers, the multi-layer cylinder comprises an upper cylinder body and multiple middle cylinder bodies, the upper cylinder body and the upper end flange are fixedly installed, the multiple middle cylinder bodies are fixedly installed through middle rings, the transpiring walls are fixedly installed on the insides of the middle cylinder bodies, a sealed
narrow gap is formed between the outer surface of each transpiring wall and the inner surface of each middle cylinder body and a transpiring wall water inlet communicated with each sealed
narrow gap is formed in the corresponding middle cylinder body. The novel transpiring wall reactor is scientific and reasonable in structural design, can effectively avoid a pyrolytic reaction in a
sewage pre-heating tube, settlement of salt and the like, and has the advantages of simple structure, convenience for disassembly and
assembly and easiness of overhaul and maintenance.
