A packed catalytic reaction tower

Abstract

The invention provides a packed catalytic reaction column which includes a pedestal. A reaction column main body is arranged on the pedestal. The reaction is composed of, from bottom to top, a water feeding zone, a supporting layer, a packing layer and a clear water discharging zone. The water feeding zone includes a column bottom. A bottom of the column bottom is provided with a column bottom head. A blow-off valve is connected to the column bottom head. The packing layer is filled with packing materials. A water outlet is arranged on an upper end of a side wall of the packing layer. A plurality of baffle plates are disposed in the packing layer. One end of each baffle plate is connected to an inner wall of the packing layer and the other end of each baffle plate is inclined downwardly. The clear water discharging zone includes a column top on which a column top head is disposed. An upper end of the column top head is provided with a packing material adding inlet. The packed catalytic reaction column solves problems that ozone, oxygen and sewage are mixed nonuniformly in a packed catalytic reaction column in the prior art, a gas utilization efficiency is not high and the packed column is liable to be blocked. The packed catalytic reaction column, combined with ozone technology, can be applied in the field of sewage treatment in various scales.

Description

technical field [0001] The invention belongs to the field of chemical equipment, in particular to a packed reaction tower used in the field of sewage treatment. Background technique [0002] With the continuous development of human society and the continuous expansion of the city, the water consumption and drainage of the city are increasing, which aggravates the tension of water use and the pollution of water quality, and the environmental problems are becoming more and more prominent. The resulting water crisis has become a socio-economic important constraints to development. [0003] my country's water resources are relatively poor. If the discharged sewage can be treated and recycled, it will not only reduce environmental pollution, but also be of great significance to alleviate the problem of water shortage. [0004] Packed reaction towers are widely used in the field of sewage treatment, such as iron-carbon packed towers, activated carbon packed towers, etc., and wast...
