Embodiment Construction

[0022] The structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] The special oxygen generating device for ozone machine described in the present invention provides oxygen with a concentration of 90% to 95% for industrial ozone machines. The normal pressure dew point of oxygen reaches below -60°C required by the ozone machine, and the energy consumption per unit of oxygen is less than 0.4KW. h / m 3 ·O 2 .

[0024] exist figure 1 In the process, the air is filtered by the filter muffler 1, blown into the cooler 3 by the blower 2, and then enters the adsorption tower 41. The adsorption tower 41 is densely filled with activated alumina, 13X molecular sieve and adsorbent sequentially from the bottom to the top. After removing moisture, nitrogen, carbon dioxide and other impurity gases in the air, oxygen flows out from the top of the adsorption tower 41 . There are two adsorption towers 41 in the ad...

Abstract

The invention discloses an oxygen generating device special for an ozone device, which sequentially comprises a filtering silencer, a gas blower, a cooler, an adsorption tower group, an oxygen buffering tank, an oxygen compressor, a drying tower group, a water cooler and a gas-water separator from upper position to lower position. The gas is filtered and then blown into the cooler by the gas blower, and enters the adsorption tower with moisture, nitrogen, carbon dioxide and other impurities in the gas adsorbed. The oxygen flows out from the adsorption tower, enters the oxygen buffering tank and is sent into the drying towers after being pressurized by the oxygen compressor, and the oxygen special for the ozone device is obtained after drying. One drying tower in the drying tower group is used for drying the oxygen, simultaneously the other drying tower can be purged for regenerating by partial oxygen special for the ozone device, the regenerated gas can enter the oxygen compressor after being performed with water cooling and gas-water separation and then reenters the drying towers for drying after being pressurized by the compressor, so that oxygen special for the ozone device can be obtained, and no oxygen discharging waste can be achieved.

Description

[0001] technical field [0002] The invention relates to a special oxygen generating device for an ozone machine. Background technique [0003] 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 sour...
