Analogous heterogeneous wet catalytic oxidation equipment and method thereof

Abstract

The invention discloses analogous heterogeneous wet catalytic oxidation equipment and a method thereof. The equipment comprises a reaction cylinder, a jacket, a circulating mechanism, a feeding mechanism and a catalytic mechanism; the outer wall of the reaction cylinder is wrapped with the jacket, and a steam pipeline is arranged on one side of the jacket; the feeding mechanism comprises a raw water pipeline, an oxidizing agent pipeline and a gas pipeline, a mixer is fixed at the top in the reaction cylinder, and a bottom outlet of the mixer is communicated with a liquid distributor; the catalytic mechanism is arranged in the middle in the reaction cylinder; the circulating mechanism comprises a circulating pump and a circulating pipeline; a circulating inlet end and a circulating outlet end are respectively arranged at the top and the bottom of the reaction cylinder; one branch of the circulating outlet end is connected to the circulating inlet end through a circulating pipeline; andthe other branch of the circulating outlet end is connected to a water outlet through a heat exchanger. According to the invention, organic matters in the wastewater can be oxidized at low temperatureand air pressure, so that the safety is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and in particular relates to a kind of heterogeneous wet catalytic oxidation equipment and a method thereof. Background technique [0002] Wet catalytic oxidation is one of the important methods to efficiently treat wastewater. The traditional wet catalytic oxidation needs to be carried out under high temperature and high pressure environment, which is easy to cause safety accidents, such as the recent explosion accidents in chemical plants. In addition to safety, many chemical wastewaters now contain chloride ions, which can cause great damage to equipment, not to mention high temperature and high pressure. Even if it is pure titanium, there is no guarantee that it can last for three years. Contents of the invention [0003] In order to solve the problems in the background technology, the present invention provides a kind of heterogeneous wet catalytic oxidation equipment and it...
