Oxygen generating device special for ozone device

Abstract

The invention discloses an oxygen generating device dedicated to an ozone machine, which sequentially includes a filter muffler, a blower, a cooler, an adsorption tower group, an oxygen buffer tank, an oxygen compressor, a drying tower group, a water cooler, a gas-water separator, and an air After being filtered, it is blown into the cooler by the blower, and then enters the adsorption tower. After absorbing moisture, nitrogen, carbon dioxide and other impurity gases in the air, the oxygen flows out of the adsorption tower and enters the oxygen buffer tank, and then passes through the oxygen compressor. After pressurization, it is sent to the drying tower, and after drying, the required oxygen for ozone machine is obtained. While one drying tower in the drying tower group is drying the oxygen, the other drying tower will be purged by part of the special oxygen for ozone machine. Regeneration, the regenerated gas will enter the oxygen compressor after water cooling and gas-water separation, and then re-enter the drying tower for drying after being pressurized by the compressor to obtain the special oxygen for the ozone machine, which ensures that there is no oxygen waste.

Description

technical field [0001] The invention relates to a special oxygen generating device for an ozone machine. Background technique [0002] Ozone machines have been widely used in the purification of industrial sewage, domestic sewage and advanced treatment of drinking water. There are three main sources of gas for the ozone machine: 1) air; 2) high-purity oxygen produced by gasification of liquid oxygen; 3) oxygen produced by on-site gas production equipment. Among them, using air as a gas source to produce ozone is a method commonly used in the early stage of ozone technology development. The advantage of this technology is that the gas source extraction process is simple, and the disadvantage is that the produced ozone concentration is low and the power consumption is large (25KW·h / kgO 3 ), which have now been phased out. The highest concentration of ozone can be obtained by using the high-purity oxygen obtained by the oxidation of liquid oxygen as the gas source for oz...

AI Technical Summary

Problems solved by technology

However, limited to the current output of a single ozone machine in China, a small pressure swing adsorption oxygen generator is generally used to produce oxygen on site to provide a gas source. The water content of the produced oxygen cannot meet the requirements for the use of an ozone machine, and an additional oxygen drying device must be added. , and when the drying device is regenerated, a part of the regenerated oxygen must be emptied and wasted, which increases the operating cost of the system
