Embodiment Construction

[0025] The present invention will be further described below in conjunction with specific embodiments. It should be understood that the following examples are only used to illustrate the present invention and not to limit the scope of the present invention.

[0026] Such as figure 1 Shown is a supercritical water oxidation reactor according to a preferred embodiment of the present invention. The supercritical water oxidation reactor mainly includes: a reactor cylinder 1, a reactor cylinder cover 2, an organic feed port 3, and an oxidant feed The material inlet 4, the water inlet 5, the reaction product outlet 6, and two partitions 7 and 8 horizontally extending inside the reactor cylinder 1, and a heating jacket 9. Among them, the reactor cylinder body 1 and the reactor cylinder cover 2 are fixed by fastening bolts 14 to form a closed container. The organic material feed port 3, the oxidant feed port 4, and the water inlet 5 are all set on the reactor cylinder cover 2, and the re...

Abstract

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 present invention relates to the fields of environmental protection and chemical industry, and more specifically to a supercritical water oxidation reactor capable of preventing clogging. Background technique [0002] Supercritical Water Oxidation (SCWO) refers to the reaction conditions where the temperature and pressure are higher than the critical temperature (374.3℃) and pressure (22.1MPa) of water, using supercritical water as the reaction medium and air Or oxygen, etc. as oxidants, completely oxidize organic pollutants in water to CO 2 And H 2 The process of O etc. [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: ①High removal rate. Under supercritical conditions, organic matter and other wastes can be completely oxidized to carbon dioxide, water, nitrogen and other harmless substances, and the removal rate of toxic substa...
