Description

High Efficiency Ozone Oxygen Contact Device {Ozone And Oxigen Supplier}

The present invention relates to a high-efficiency ozone oxygen contact device, and more particularly, to a sterilization and oxygen dissolution system required for a wastewater treatment process using a microbial treatment method and a water treatment process in aquaculture.

Ozone is a gas with relatively low solubility in water, so when it is applied to water treatment, it must be dissolved with good efficiency using a gas-liquid mixing device.

As a system for effectively dissolving ozone from the ozone generator in the treated water, most of the waste water treatment is an acid reactor using a ceramic porous diffuser.

This provides a porous diffuser at the base of the reaction, whereby the ozone-containing gas is dispersed into the water as a fine bubble through the diffuser. As bubbles rise to the surface from the water, ozone in the bubbles dissolves into the water through the gas-liquid interface.

One of the important requirements of the reactor is that the dissolution rate at this time should be high, which has a big disadvantage of dissipating a considerable amount of ozone at 20%. In addition, the amount of unreacted ozone released into the air is high, so an unreacted ozone removal facility must be installed to remove it.

Accordingly, the present invention has been made in view of the problems of the conventional ozone contact technology, the object of which is to reduce the operating cost in the field by maximizing the dissolution rate of ozone obtained by using pure oxygen of 99% or more and the by-product oxygen. An object of the present invention is to provide a high-efficiency ozone oxygen contact device capable of obtaining high quality water.

A high efficiency ozone oxygen contact device is provided.

The ozone supply device is an ozone generator that converts oxygen molecules into ozone molecules by irradiating pure oxygen with ultraviolet rays, and an ozone pressure regulator that controls the supply pressure of ozone generated by the ozone generator and supplied to the dissolution tank. And an ozone supply control valve for supplying ozone adjusted to a predetermined pressure by the ozone pressure regulator to the pressure dissolving tank, and the injector is an inlet pump for pressurizing and supplying water to dissolve oxygen; An inlet valve for supplying water pressurized by an inlet pump, an inlet pipe to which the inlet valve is connected, and at least one injection nozzle connected to the inlet pipe and installed in the dissolution tank to inject water into a particulate state . The spray nozzle is a device for maximizing the contact area between ozone and oxygen and the water to be treated to dissolve the whole amount.

In addition, the dissolution tank further comprises a other gas discharge pipe and another gas discharge valve for discharging the other gas generated in the substitution process with the substances to be removed to maintain the concentration of ozone oxygen to the outside, The dissolution tank further includes a dissolved water discharge pipe and a valve for discharging ozone oxygen dissolved water in which ozone oxygen is dissolved.

The present invention is an injection nozzle for injecting the water to dissolve the oxygen and oxygen by ozone in the form of particulates, and foreign matters to be removed, including organic matter in the water sprayed by maintaining ozone at a constant pressure in the pressure dissolution tank, the core technology of this technology At the same time, the strong oxidation and sterilization action, which is characteristic of ozone, maximizes the treatment efficiency by widening the contact area of the particulate-type spray and maximizes the dissolved oxygen of the byproduct.

In addition, the present invention is the ozone by the back pressure acting in the pressure dissolving tank by contacting the water in the pressure dissolving tank to supply the fine particles in order to purify, sterilize, oxidize and maintain a high concentration of oxygen in sewage, waste water, purified water, sewage and aquaculture plant In other words, the solubility is maximized by maximizing the reaction distribution of oxygen.
