Description

Chlorine dioxide mixing ejector

The present invention relates to a chlorine dioxide mixing injector that provides sterile water by mixing chlorine dioxide in the feed water, and more particularly, by providing a sterile water mixed with chlorine dioxide in the feed water by a simple structure. The present invention relates to a chlorine dioxide mixing injector which provides excellent quality, economical efficiency, and reliability of chlorine dioxide because chlorine dioxide is mixed and injected at a constant mixing ratio in proportion to the negative pressure generated by the injection speed of the feed water.

In general, chlorine dioxide is an oxygen-based disinfectant and disinfectant. It is a water-soluble oxidant in which gas having strong sterilizing power, deodorization, and bleaching power is dissolved in a solution.

Such chlorine dioxide has the following characteristics.

First, unlike chlorine, it is stable in solution and slow in reaction with water, so that sterilizing power can be maintained in a wide pH range, and is suitable for cooling water disinfection or pH control which is difficult to adjust in alkaline pH.

Secondly, after chlorine disinfection, many bacteria reappear, and this chlorine oxide greatly suppresses it.

Third, the bacterial membranes interfere with heat transfer, causing water to precipitate, insoluble salts, and activating anaerobic bacterial growth. Chlorine dioxide has a strong biomass permeability, which is very effective in removing bacterial membranes.

Fourth, chlorine dioxide has the least toxicity among the disinfectants.

Fifth, since it does not react with ammonia, it does not form chloramine, which has a high potential for toxicity, and halogen organic compounds such as chloroform, a carcinogen, are not generated to an appreciable level.

In addition, compared to chlorine, dioxins are reduced, economical, safe and easy to maintain, and environmentally friendly.

Such a device for producing sterilized water using chlorine dioxide is to dilute chlorine dioxide in sprayed water through a mixer and spray it through an ejector. Such a device inputs an appropriate amount of chlorine dioxide in accordance with a change in the amount of sprayed water. There was a problem that was difficult to do.

That is, when the amount of chlorine dioxide injected is less than the appropriate amount compared to the amount of injection water, the disinfection efficiency is lowered, on the contrary, when the amount is higher, there is a problem in that the economy is inferior.

The present invention has been invented to solve the above-mentioned problems of the prior art, and provides an apparatus for providing sterilized water by mixing chlorine dioxide with the supply water by a simple structure, and thus provides excellent economics.

The present invention has the purpose of providing excellent quality, economical efficiency, and reliability of sterile water because chlorine dioxide is mixed and injected in a constant mixing ratio in proportion to the negative pressure generated by the injection speed of the feed water.

This invention,

A chlorine dioxide supply path for supplying chlorine dioxide generated from a chlorine dioxide generator to one side rear of the injection space portion formed in the center of the main body, a supply path for supplying and supplying the supply water to the front and rear positions opposite to the center, and the injection of the supply water. By forming a mixing furnace for inhaling and mixing chlorine dioxide by the negative pressure generated in the injection space portion by mixing and injecting chlorine dioxide in the feed water, the chlorine dioxide supply passage to install a check valve for preventing backflow Is achieved.

The mixing port of the supply port and the mixing furnace of the feed water supply passage which is located opposite to the front and rear of the injection space portion is characterized in that the mixing port of the mixing furnace has a larger diameter than the supply port of the supply water.

The present invention provides sterilized water by a simple structure in which the chlorine dioxide is sucked, mixed and injected at a negative pressure generated by the injection speed of the feed water, but is proportional to the negative pressure generated by the injection speed of the feed water. Is inhaled at a constant mixing ratio, mixed and injected, and also prevents the reverse flow of the chlorine dioxide, thereby improving the quality of the sterilized water, as well as providing the economy and reliability.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.

In the chlorine dioxide mixed injector of the present invention, as shown in FIGS. 1 to 4, an injection space part 10 is formed in the center of the body 5,

The injection space portion 10 has a chlorine dioxide supply passage 13 for supplying chlorine dioxide generated by the chlorine dioxide generator 20 at one side and a supply passage for spraying the supply water to the front and rear positions opposite to the center ( 11) and by forming a mixing furnace 12 in which chlorine dioxide is sucked by the negative pressure generated in the injection space 10 during the injection of the feed water to mix the feed water and chlorine dioxide. Inhalation of the chlorine dioxide in proportion to the negative pressure generated by the injection speed and mixed injection,

The chlorine dioxide supply passage 13 is formed by installing a check valve 14 for preventing backflow.

That is, negative pressure (negative pressure) is generated in the injection space part 10 as the supply water is injected into the mixing furnace 12 through the supply port 11a of the supply path 11, and the chlorine dioxide is generated by the negative pressure. Chlorine dioxide supplied from the supply passage 13 is sucked and supplied to the mixing furnace 13, which is proportional to the supply amount of the feed water because the chlorine dioxide is sucked in proportion to the negative pressure generated according to the injection speed of the feed water. As it is sucked into it will maintain a constant mixing ratio.

At this time, the supply port (11a) of the supply water supply path 11 and the mixing port (12a) of the mixing passage 12 which are opposed to the front and rear of the injection space 10 is mixed in the mixing furnace than the supply port of the supply water It is preferable that the sphere forms a large diameter.

In addition, the front and rear of the main body 5 is provided with a supply port 31 connected to the supply passage 11, the injection port 32 connected to the injection passage 12 is screwed to the main body by the connection cap (41) (42) Configured to engage.

As an unexplained reference numeral 50 denotes a solenoid valve for controlling the feed water supply.

Hereinafter, the operation and operation of the present invention will be described.

The present invention provides sterilized water that constantly mixes chlorine dioxide in proportion to the feed water supplied through the tap water inlet line, and the tap water (water treatment plant), sewage / sewage and wastewater treatment plants, fisheries / farms, pulp / paper processing, industrial It is intended to be widely used for water, food / processing water, petrochemical, and the like.

In more detail, when the solenoid valve 50 of the tap water inlet line is opened, the supply water is supplied through the supply passage 11 of the main body 5.

As the supply water supplied to the supply path is injected toward the mixing furnace 12 through the supply port 11a, negative pressure (negative pressure) is generated in the injection space part 10, and at the same time, the injection space part By the negative pressure generated in (10), the chlorine dioxide supplied through the chlorine dioxide supply passage 13 is sucked and supplied to the mixing furnace 12 together.

In particular, a negative pressure (negative pressure) is generated differently according to the speed at which the feed water is injected into the mixing furnace 12 through the supply port 11a of the supply passage 11, and the chlorine dioxide supply is caused by the negative pressure generated differently. Since chlorine dioxide supplied from the furnace 13 is proportionally sucked and supplied to the mixing furnace 13, chlorine dioxide is sucked in proportion to the amount of the supply water according to the injection speed of the supply water, thereby maintaining a constant mixing ratio. will be.

In this way, the feed water and chlorine dioxide supplied to the mixing furnace 12 is mixed and sprayed into the sterilization water, it is possible to provide excellent quality of the sterilization water by providing a mixture of chlorine dioxide in a constant mixing ratio in proportion to the supply water.
