Catalytic oxidation reaction apparatus of trickle bed

Abstract

The invention relates to a trickle-bed catalytic oxidization reactor, composed of waste water tank, premixing reactor, reactor, gas-liquid separator, condenser, oxygenated part and temperature-control part, which are connected together by pipelines and valves, where the reactor adopts segment heating and temperature control to ensure the reaction at the isothermy. The reactor is set with side sampling mouth able to collect the samples in different positions of the reactor, and has backflushing part able to regularly wash the catalyst in the reactor, effectively the salt stain problem always occurring in the course of wet-oxidizing actual high-concentration organic industrial waste water. It can be used to research the law of effect of technical operating conditions on the catalytic wet-oxidization reaction course of high-concentration, difficult- degradation, poisonous and harmful organic waste water discharged by the industries such as chemical industry, medicine industry and pesticide industry, has a very important significance in further enlarging the application field and range of wet oxidization and has good market prospect.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a trickle bed catalytic oxidation reaction device. Background technique [0002] With the rapid development of petrochemical, pharmaceutical, pesticide, dyestuff and other industries, the types of refractory organic compounds in wastewater are increasing day by day, and the degree and scope of their harm are increasing. A large number of studies have shown that wet oxidation (WO) is an effective method for treating high-concentration refractory organic wastewater, but the high temperature and pressure in the WO process and the high requirements for equipment materials limit its popularization and application. In order to reduce the reaction temperature and pressure, the research and development of catalytic wet oxidation (CWO for short) technology with heterogeneous catalysts has become a research hotspot. Catalytic wet oxidation technology is curren...
