Description

Sterilization and purification device for water treatment system

The present invention relates to a sterilization and purification apparatus for a water treatment system that sterilizes harmful microorganisms in water by using ozone and ultraviolet rays, decomposes and removes organic matter, and improves the deodorization effect, and more particularly, minimizes surplus ozone gas and increases the ozone dissolution rate. It relates to a sterilization and purification device for water treatment systems of fountains and water play facilities that can be maximized.

With the recent economic development and rapid development of the tourism industry, a water treatment system for removing various foreign substances and pollutants in water is widely used in various industrial fields such as recreation facilities and water play facilities to suit the purpose of using contaminated water.

In particular, the recirculation water used in fountains and water play facilities is contaminated with body fluids such as saliva and sweat and fine dust due to the nature of being continuously exposed to the human body and the atmosphere during the circulation process. It is very important to sterilize and purify water because it causes water-related diseases as well as unclean and unpleasant odors.

In the water treatment field today, ORED sterilization method, AOP (Advanced Oxidation Process) sterilization method, chlorine sterilization method, ozone sterilization method, ultraviolet sterilization method, etc. are known.

For example, in Patent Document 1, ozone supplied from an external ozone generator reacts with ultraviolet rays generated from an ultraviolet lamp to generate organic decomposition substances made of OH radicals to sterilize contaminated water, and untreated residual pollutants are converted to granular activated carbon. Disclosed is an advanced water purification apparatus having a structure for treating by adsorption.

However, if the granular activated carbon is not replaced frequently, the adverse effect of increasing water pollution occurs, and the spent granular activated carbon is industrial waste and has to be entrusted to a specialized company to be treated legally.

In Patent Document 2, the ozone sterilization method and the ultraviolet sterilization method are combined to expose and contact ozone to the ultraviolet irradiation area to increase the dissolution rate of ozone, and OH radicals are generated during the dissolution process to oxidize organic pollutants including microorganisms in water. , an oil-water sterilization device using ultraviolet rays and microbubbles for sterilization and removal is disclosed.

However, since this is merely a structure in which the air pumped from the blower is microbubbled through the pores of the air diffuser to enhance the sterilization effect, there is a limitation in that the ozone dissolution rate is significantly lowered.

The main action and operating principle of the sterilization and purification apparatus for a water treatment system according to an embodiment of the present invention configured as described above will be described as follows.

First, the inlet pipe 11 of the chamber 10 flows the ozone gas generated from the ozone generator O at a high speed, and the injector I that mixes the water filtered by the filter F while sucking it and ejects it at a high pressure and When connected through a pipe, ozone gas and water are supplied through the inlet pipe 11 under the pressure of the injector I through the mixing pipe 40 in the chamber 10 .

At this time, ozone gas and water passing through the mixing tube 40 cause a vortex phenomenon while repeating rapid passage and slow passage, and in this process, the particle size of ozone gas is divided into fine particles (100 ~ 500㎛) and water It is sent to the lower part of the chamber 10, that is, the lower space of the perforated plate 50, in a state in which contact efficiency is maximized.

Then, the micronized ozone gas and water rise from the lower part of the chamber 10 to the upper part and pass through the perforated plate 50 in stages while being secondarily supplied to the water (in water) in the chamber 10 in an ultra-micronized state.

That is, the ozone gas and water rise due to the blades 51 and holes 52 formed by perforating the perforated plate 50 with irregular sawtooth shapes of irregular size and lifting it up at an acute angle or twisting it in the front and rear or left and right directions. The passage speed (flow velocity) increases according to the Since the contact area with water is increased, the ozone dissolution rate can be maximized.

Then, the ultrafine ozone gas dispersed and dissolved in the water reacts with the ultraviolet rays irradiated from the ultraviolet lamp 30 while rising and decomposes to generate OH radicals with strong oxidizing power.

Since these OH radicals have a stronger potential difference (3.08V) than ozone, they have a stronger sterilization power than ozone, sterilize various bacteria, viruses and harmful microorganisms in water, and decompose organic matter to effectively remove purifying and odors.

Therefore, fresh and clean sterilization and purification of water can be circulated and supplied to fountains and water play facilities, so that a more sanitary and clean environment can be maintained and water-borne diseases can be effectively prevented.
