Abstract

The invention relates to an air-supply-type self-excited oscillation pulse jet aerator, and belongs to the technical field of environment-protecting devices. The invention relates to an improvement of the structure of a self-excited oscillation pulse jet aerator used for processing sewage. With the aerator provided by the invention, problems such as high energy consumption and low air-liquid mixing efficiency of an existing jet aerator are solved, and oxygenation efficiency is improved. The aerator comprises a housing. In the housing, form one side end face to the other side end face of the housing, a water inlet chamber, a nozzle, an air absorption chamber, a self-excited oscillation chamber inlet pipe, a self-excited oscillation chamber, a self-excited oscillation chamber outlet pipe, and a diffusion chamber are sequentially arranged. The inlet of the water inlet chamber is arranged on one side end face of the housing, and communicates with the nozzle. The nozzle communicates with the air absorption chamber. The air absorption chamber communicates with the self-excited oscillation chamber through the self-excited oscillation chamber inlet pipe. The self-excited oscillation chamber communicates with the diffusion chamber through the self-excited oscillation chamber outlet pipe. The outlet of the diffusion chamber is arranged on the other side end face of the housing. An air inlet is arranged on a side wall of the housing, and communicates with the air absorption chamber.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and relates to the improvement of the structure of a self-excited oscillation pulse jet aerator for treating sewage, in particular to an air supply type self-excited oscillation pulse jet aerator. Background technique [0002] At present, in the mainstream biochemical treatment process of sewage treatment, aeration equipment is the main energy consumption equipment, and the power consumption of the aeration system accounts for about 50-70% of the total power consumption of the treatment plant. Achieving the aeration effect of the aeration equipment and at the same time achieving the purpose of saving energy and reducing consumption has become a common problem in the industry. [0003] Commonly used aeration methods mainly include blast aeration, mechanical aeration and jet aeration. The jet aerator using the jet aeration method is an aeration equipment that integrates ...
