Description

{Chlorine Dioxide Generator with Fixed Quantity}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for generating chlorine dioxide and, more particularly, to a chlorine dioxide generating apparatus capable of stably controlling and generating quantities.

Chlorine dioxide is widely applied in many fields and has a very high commercial and industrial importance. At present, chlorine dioxide is consumed in large quantities as a bleaching agent for wood pulp, paper, oils and fats, petroleum, resins and powders.

Due to the recent deregulation, chlorine dioxide has been used increasingly as a disinfectant and disinfectant in the food processing industry. The new federal guidelines have allowed the use of chlorine dioxide for meat, milk products manufacturing, fruit and vegetable processing, and processed foods. In most cases, chlorine dioxide does not cause organoleptic impairment of food.

Chlorine dioxide is also widely used as a pollution control agent and a water treatment agent in the wastewater treatment industry. Chlorine dioxide is an excellent sulfur remover, used in washing towers used in wastewater, and also in the fat (refined), gas and oil industries.

Chlorine dioxide has been increasingly used as an environmental and microbial control agent due to its unique properties. Chlorine dioxide shows high reaction specificity for certain industrial pollutants such as sulfur, amines, mercaptans and cyanides, but does not show reactivity for ammonia or most organic compounds.

The highly selective nature of chlorine dioxide is important for its bactericidal action. Unwanted sterilization by-products such as trihalomethane and polychlorobiphenyl are not produced and chlorine or hypochlorite is produced. Chlorine dioxide shows its effect over a wide pH range, does not dissociate in solution (without forming ions), has a fast bactericidal action, and does not accumulate in the treatment solution.

Chlorine dioxide is prohibited to be transported and stored, and its transportation and storage are dangerous, so it is mostly produced and consumed locally. Chlorine dioxide has been produced by several conventional chemical and electrochemical processes. The most common production method is to acidify an aqueous solution of sodium chlorite. Strong acids such as sulfuric acid and hypochlorous acid have a high yield of chlorine dioxide, while weak acids such as citric acid and lactic acid have a very low yield.

The acidification of chlorite to chlorine dioxide increases its yield when chlorine donors such as hypochlorous acid or chlorine gas are present. Hypochlorous acid, strong acid and chlorine gas must be produced and stored locally, so there is an additional risk, which puts the burden on the end user to regular inspection.

The electrochemical generation apparatus is designed to solve such a problem. Such an electrochemical generation apparatus utilizes a single precursor, which typically uses chlorous acid. The resulting chlorine dioxide is separated from the electrolyte solution by the gas permeable membrane. However, chlorine dioxide produced in this way is not widely used because of the disadvantages such as generation of explosive hydrogen gas accompanied with a high cost cost. Such an electrochemical generation apparatus has a great disadvantage that it uses a lot of electric power, and its manufacturing cost is very high due to the complexity of the structure.

A better and alternative method of producing chlorine dioxide is by photochemical oxidation. For photochemical reactions of oxyanion of chlorine dioxide and chlorine, see E. J. Brown and M. et al. Reported by M. Cheung (1932), and are disclosed in U.S. Patent Nos. 2,043,284, 2,457,285 and 2,683,651.

More recent techniques for photochemical methods are disclosed in U.S. Patent Nos. 4,414,180 and 4,456,511, the inventors of which are Fisher. This technology relates to an apparatus for generating chlorine dioxide from sodium chlorite by externally inserting a fluorescent lamp. The sodium chlorite is photochemically oxidized to produce chlorine dioxide, which is removed from the aqueous solution along with nitrogen gas or air.

A more detailed technique is also described by the inventor. U.S. Patent No. 4,874,489 to J. Callerame, which discloses a tubular chamber containing sodium chlorite. An ultraviolet light source, that is, a low-pressure mercury vapor lamp, is provided in the container, and the inner wall of the container is made of an ultraviolet reflector such as polished aluminum. When the concentration of chlorine dioxide reaches 10% by weight and the entire reaction product is consumed in the vessel, the reaction is terminated. 10% by weight is the highest limit defined by the explosive nature of chlorine dioxide. In addition, although a UV lamp is widely used as a light source in a chlorine dioxide generating apparatus using such a photochemical method, it is disadvantageous in that it is difficult to reduce the size and weight of the apparatus due to the size of the ultraviolet lamp.

And, similar to U. Kallarame's patent, U.S. Patent No. 4,877,500 discloses a technique for producing chlorine dioxide by a photochemical method using a mixture of chlorine and oxygen and an aqueous solution of sodium hypochlorite. As in the Kalalame patent, the aqueous solution remains in the tubular vessel until the maximum concentration of chlorine dioxide reaches 10 wt.%. Afterwards, the entire reaction contents containing chlorine dioxide are recovered and transported to the site. There have been reports of two explosions in the photochemical reactions of oxygen and chlorine.

A technique for improving safety in a photochemical method is disclosed in U.S. Patent No. 6,171,558 by Simpson. This patent discloses a technique of providing an ultraviolet lamp in a container containing an aqueous chlorite salt. In this technique, aqueous chlorites salify the flow tube by air or gas spray. This configuration effectively recovers chlorine dioxide, thereby reducing the risk of explosion due to the accumulation of chlorine dioxide.

Conventional chlorine dioxide generating devices have been somewhat improved in terms of safety, but the following problems still remain.

(1) In the prior art, it is impossible to continuously supply fresh sodium chlorite, and it is impossible to remove spent reaction products by chlorites such as sodium chloride.

(2) The reaction of the conventional chemical production apparatus uses a strong acid such as hydrochloric acid, so that it is very difficult to control by the reaction and there is a problem that general users are dangerous to handle.

(3) Conventional electrochemical generation apparatus has a disadvantage in that it is difficult to control the concentration, and it uses a lot of electric power as well as hydrogen, and the production cost is very high due to the complexity of the structure.

(4) In the conventional photochemical generation technology, it is difficult to directly control the generation of chlorine dioxide by adding a chlorite precursor, and the production of chlorine dioxide must be controlled by the luminous intensity of the lamp and the gas discharge ratio.

(5) Conventional electrochemical and photochemical production apparatuses are complicated in device configuration, difficult to scale up, difficult to directly control the injection amount of chlorite, and difficult to stably produce chlorine dioxide due to this injection.

As such, chlorine dioxide is widely used industrially and commercially, and its use is likely to increase. Especially, due to the instability of sterilization and the distribution process, massive waste loss cost is produced in the fruit part, and the time required for the inspection due to the packaging of the product is wasted, the concern about safe food is increased, It is necessary to develop a stable and efficient apparatus for producing chlorine dioxide because it is necessary to develop a technology for prevention of corruption and enhancement of preservation.

The storage device 500 used in the embodiment of the present invention A discharge pipe 530 for connecting the chlorine dioxide gas to the inside and the outside of the reactor, and a storage tank 550 for storing the chlorine dioxide gas transferred from the discharge pipe 530. It is preferred that the reservoir 550 use a water tank to store the chlorine dioxide gas stably and effectively.

Hereinafter, a chlorate injection device and a citrate injection device will be described in detail with reference to FIG. 2 as a key feature of the present invention. 2 is a schematic view showing a configuration of a citric acid injector 300 used in an apparatus for producing chlorine dioxide according to an embodiment of the present invention. The capsules 220 and 320 and the dispensers 230 and 330 have the same structure and the structure of the injector of the citric acid injector is the same as that of the injector of the citrate injector. A description of the structure of the chlorite injector will be omitted.

1 and 2, a citric acid injector 300 used in an apparatus for producing chlorine dioxide according to an embodiment of the present invention includes a capsule 320 for storing the citric acid, A dispenser 330 for injecting a predetermined amount of citric acid into the reactor 100 by a pressing force and a pushing device 410 and a servo motor 450 for linearly driving the dispenser 330 at a constant speed.

The dispenser 330 includes a cylindrical fixing table 331 mounted on the injection port on the upper part of the reactor 100 and a housing 333 having a cylindrical dispenser 330 removably attached to the fixing table 331 by vertical movement, A cylindrical injection nozzle 335 fixed to the center of the inside of the housing 333 of the dispenser 330 and having a plurality of through holes formed on the side thereof and a cylindrical injection nozzle 335 fixed to the inner surface of the housing 333, And a spring 339 provided between the ring-shaped step and the lower end of the injection nozzle 335.

More specifically, an apparatus for selectively injecting citric acid while a cylindrical fixing table 331 opened to an injection port formed at an upper end of a reactor 100 and dipping or attaching the citric acid injector 300 to the fixing table 331, The pushing device 410 and the servomotor 450 move the capsule 320 and the dispenser 330 to determine the amount of citric acid to be injected.

The dispenser 330 used in the embodiment of the present invention is characterized in that the opened cylindrical housing 333 extends downward from the capsule 320 in which the citric acid is stored and a plurality of through holes 315 are formed in the center of the inside of the housing 333, The cylindrical injection nozzle 335 is fixed. A spring 339 is provided between the ring-shaped step that is fixed to the inner side surface of the housing 333 and surrounds the side surface of the injection nozzle 335 and the lower end of the injection nozzle 335, The lower end of the injection nozzle 335 supported by the spring 339 moves upward and the ring-shaped step is moved to the lower end of the injection nozzle 335 The through hole 315 formed in the side surface of the injection nozzle 335 is opened and citric acid stored in the capsule 320 is injected into the reactor 100 through the through hole 315 of the injection nozzle.

As shown in Fig. 2, when the dispenser 330 and the fixing table 331 are detached and separated (left side in the drawing), the entire injection nozzle 335 is sealed by the ring-shaped step due to the elastic force of the spring 339 The citric acid stored in the capsule 320 can not be injected into the reactor 100 through the injection nozzle 335 and when the dispenser 330 is mounted or docked on the fixing table 331, And the through hole 315 is opened to allow the citric acid to be injected into the reactor 100 through the through hole.

This structure induces the opening and closing of the nozzle for injecting citric acid into the reactor 100 in a stable and easy manner merely by the linear movement drive of the servomotor 450 and the pushing device 410, It is possible to provide an improved chlorine dioxide generating apparatus which can easily reduce the production cost by eliminating the risk of explosion which may be caused by the injection of citric acid and stably controlling the injection amount of citric acid or the amount of produced chlorine dioxide.

FIGS. 3 and 4 are views showing a structure of a citrate injector according to another embodiment of the present invention, which differs in the structure of injection nozzles.

3, the dispenser 330 applied to the embodiment of the present invention includes a cylindrical housing 333, an injection nozzle 335 fixed and positioned at the center of the inner wall, a ring- And a spring 339 fixed to the inner lower end of the housing. The head of the injection nozzle 335 is tapered so as to become narrower toward the lower end, It is preferable that a plurality of linear grooves 337 formed in a spiral or downward at regular intervals are formed.

The formation of the tapered injection nozzle 335 head and the spiral or linear groove 337 on the outer surface of the head causes the dispenser 330 to shake the injection nozzle 335 when docked on the fixing table 331, Thereby preventing leakage of the citric acid solution into the reactor and guiding the flow of the citric acid solution that is leaking or nonuniform. When necessary, the long rod-shaped nozzle pin 338, which reaches the inside of the reactor, And an auxiliary device capable of injecting the citric acid solution into the reactor can be implemented.

The housing 333 of the dispenser 330 applied to the embodiment of the present invention is preferably made of a plastic material because the capsule 320 in which the citric acid solution is stored can be easily and stably And the capsules 320 can be easily replaced.

When the dispenser 330 is docked on the fixing table to move the injection nozzle 335 in the upward direction because the capsule 320 is in contact with the ring-shaped step 332, 315, the upper portion of the housing 333 is completely exposed to the citric acid solution, so it is difficult to use the metal material which reacts with the acidic solution to corrode.

In addition, it is preferable to use the metal support 336 for stable fixing at the lower end portion where the injection nozzle 335 is fixed. Accordingly, in the case of the fixing stand 331, the dispenser 330 moves downward, It is preferable to use a magnet made of a magnetic material so as to have an adhesive force automatically even when an external force is not supplied.

4, another embodiment of the present invention is characterized by mounting a long rod-shaped nozzle pin 338 downward in a groove 337 formed in the head of the injection nozzle, Thereby preventing leakage of the citric acid solution flowing out of the reactor and inducing the citric acid solution to flow down into the reactor precisely along the nozzle pin 338. Here, the nozzle pin 338 can be easily detached and attached to the groove formed in the head of the injection nozzle, and it becomes possible to indirectly control the injection rate or injection amount of the citric acid solution selectively by changing the pin hole size.

FIG. 5 is a graph showing the relationship between the concentration of 28% NaClO ₂ and 50% of citric acid in 0.3 ml, 0.6 ml, and 0.9 ml of each of the different amounts of chlorine dioxide produced by a single operation of the dispenser using a chlorine dioxide generating apparatus capable of generating quantities according to an embodiment of the present invention Is a graph showing the concentration of chlorine dioxide gas produced over time in the case where a fixed amount is introduced at a ratio of 1: 1.

As shown in FIG. 5, it can be seen that as the concentration is increased to 0.3 ml, 0.6 ml and 0.9 ml, the concentration of chlorine dioxide gas produced and the rate of generation of chlorine dioxide gas with time increase relatively stably. This is advantageous in that it is easy to quantitatively inject the chlorite solution and the citric acid solution through the dispenser 330, and the process speed can be easily controlled by selectively injecting a fixed amount into the reactor 100 as needed.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone with it will know easily.
