Description

An anti-clogging electrocatalytic cell

technical field

The invention relates to the technical field of electrocatalytic cells, in particular to an anti-blocking electrocatalytic cell.

Background technique

Electrocatalytic technology is a new type of treatment process in industrial wastewater treatment. It energizes the electrode plate and oxidizes the pollutants in the sewage under the synergistic effect of the catalyst, and finally achieves the purpose of oxidative degradation of COD.

Electrocatalytic technology is very effective in treating sewage, so catalytic technology is a necessary process in the sewage treatment system at this stage. However, in practical applications, the catalyst often blocks the inlet and outlet pipes of the electrocatalytic cell, resulting in the paralysis of the entire sewage treatment system.

Referring to Fig. 1 and Fig. 2, in order to prevent the catalyst from entering the water inlet and outlet pipes of the electrocatalytic cell at this stage, the following two methods are usually adopted: 1. Filter type. 2. Stencil type plus support structure.

For the first method, the filter is only perforated on the surface of the plate with the size of the pipe, and is directly bonded to the end of the pipe with glue. Although this method is simple to process, the contact area between the pipe surface and the sewage is small, and it is easy to block. The water inlet pipe is slightly blocked, causing the outlet pressure of the water supply pump of the electrocatalytic cell to increase. The outlet pipe is slightly blocked, and the inlet pressure of the drain pump increases. Both conditions can cause damage to the filter, allowing the catalyst to enter and block the line.

For the second method, the mesh plate type adds a support structure. The mesh plate is easy to deform, and many support plates are needed, so the gap between the support plates is small, so that there is no large catalyst extraction hole at the bottom of the electrocatalytic cell. At the same time, the inlet and outlet pipes need to be separated by a partition, and the nozzles of the inlet and outlet pipes are located at the same height of the electrocatalytic cell, which is not conducive to the circulation of sewage in the electrocatalytic cell and reduces the efficiency of sewage treatment.
