Description
Technical Field
The utility model relates to the technical field of ozone generators, in particular to a heat exchange ozone generator system.
Background
The preparation of industrial ozone generally uses instrument wind or power wind as raw materials, firstly uses a gas storage tank to stabilize pressure, then uses a cold drier to dehydrate and deoil and filter dust, then uses an oxygen-enriched machine to support nitrogen to obtain an oxygen-enriched source, and the oxygen is subjected to electrochemical reaction in a high-voltage discharge type ozone generator, so that the ozone is manufactured. When the ozone generator works, a large amount of heat energy is generated, cooling is needed, otherwise, ozone can be decomposed while being generated due to high temperature. The water-cooled ozone generator has good cooling effect, stable operation, no ozone attenuation and long-time continuous operation. The ozone generator has the advantages of mature technology, stable operation, long service life, large ozone yield (the single machine can reach 1 Kg/h) and the like, so the ozone generator is the most widely used ozone generator in relevant industries at home and abroad. However, the process has the advantages of complex ozone preparation structure, high cost, high investment and high operation and use cost, and not only does auxiliary equipment occupy more space, but also needs to further improve the benefit and reduce the investment and operation cost.
To improve the benefit, the investment on equipment is reduced, the process flow is optimized, the failure rate of the equipment is reduced, and the energy consumption is reduced. Using instrument wind as raw material, only the unit price of the instrument wind is 0.37 yuan/m 3 If other surplus pure oxygen is utilized, the investment cost of the equipment for preparing the instrument wind and the oxygen is saved.
The method comprises the steps of using instrument wind (clean and dry compressed air) as a raw material, separating nitrogen from oxygen by an oxygen enriching machine (PSA air separation system), and collecting oxygen as a raw material gas (the raw material gas contains inert gas, carbon dioxide and a small amount of nitrogen, and is not pure oxygen, so called a rich oxygen source), wherein the ozone is generated by oxygen, the content of oxygen in the air is only 21%, so that the ozone concentration generated by an air type generator is relatively low, and the oxygen purity of the oxygen type oxygen generator is above 90%, so that the ozone concentration of the oxygen type generator is high. The pure oxygen is higher than the oxygen-enriched source, so that the concentration of ozone generated is higher, the electric power loss of inert gas, carbon dioxide and a small amount of nitrogen in the oxygen-enriched source when electrochemical reaction occurs in the high-voltage discharge type ozone generator is reduced, and the operation cost is reduced.
Substantially all generator ozone production is sensitive to changes in coolant temperature due to the greater effect of heat dissipation on ozone production. With the increase of the cooling water temperature, the relative ozone yield is obviously reduced, the cooling water temperature used by a common ozone generator is controlled to be 15-25 ℃, and 2500-4000L of cooling water at 15-25 ℃ is needed for producing 1kg of ozone by the common water-cooled ozone generator. Increasing the coolant flow helps to compensate for both the reduced capacity due to the high power density (gas temperature) and the loss of dielectric damage due to the increased dielectric temperature. However, in reality, cooling water of most enterprises has poor water temperature and water quality indexes, so that the capacity of the ozone generator is too low and the failure rate is too high.
