The invention provides an anti-blocking super-critical water oxidation reactor. The anti-blocking super-critical water oxidation reactor comprises a reactor drum, and a reactor drum cover covering the reactor drum. The reactor drum cover is provided with a feed inlet, the bottom of the reactor drum is provided with a reactant outlet. The anti-blocking super-critical water oxidation reactor also comprises at least one partition extending horizontally in the reactor drum, an area above the partitions is a super-critical water oxidation area, and an area below is a sub-critical area. A heating sleeve is arranged on the outer side of the drum body of the super-critical water oxidation area. The outer side of the drum of the sub-critical area directly contacts with the air. The partitions are provided with holes communicated with the super-critical water oxidation area and the sub-critical area. Innovatively, the partitions can divide the inside of the reactor into the super-critical water oxidation area and the sub-critical area, the problem of blockage of the sediment salt to the outflow pipelines is solved, and the novel anti-blocking super-critical water oxidation reactor is provided.
Description
technical field [0001] The invention relates to the fields of environmental protection and chemical industry, in particular to an anti-clogging supercritical water oxidation reactor. Background technique [0002] Supercritical Water Oxidation (SCWO for short) refers to using supercritical water as the reaction medium under the reaction conditions where the temperature and pressure are higher than the critical temperature (374.3°C) and pressure (22.1MPa) of water, Use air or oxygen as the oxidant to completely oxidize organic pollutants in water into CO 2 and H 2 The process of O et al. [0003] SCWO uses the unique properties of supercritical water to convert organic waste into environmentally sound products. Its advantages are shown in the following aspects: ① The removal rate is high. Under supercritical conditions, organic matter and other wastes can be completely oxidized into harmless substances such as carbon dioxide, water, nitrogen, etc., and the removal rate of t...
