Description

Oxidant generation system {SYSTEM FOR GENERATING OXIDIZERS}

The present invention relates to an oxidizing agent generation system, and more particularly, to a technique for continuously generating a high concentration of chlorine and increasing the life of electrodes in an electrolyzer for generating an oxidizing agent in the oxidizing agent generation system.

In general, an apparatus for generating electrolytic chlorine (ClO-, HClO, NaClO, NaClO2) by electrolyzing salt water is widely known. The electrolytic chlorine produced in this way is widely used as an oxidizing agent in water purification plants, sewage treatment plants, swimming pool sterilization and sterilization devices, food service sterilization devices, and the like.

Briefly looking at the electrolysis reaction in which electrolytic chlorine is generated, chlorine ions (Cl-) are converted into chlorine gas (Cl2) through an anodic reaction in the electrolysis tank. The anodic reaction is a reaction for generating oxygen (O2) by decomposition of water (H2) and a competitive reaction, and its efficiency is determined according to the characteristics of the anode electrode, the concentration of salt water, and the electrolysis method. Meanwhile, during the anodic reaction, hydrogen (H2) and hydroxide ions (OH-) are generated at the cathode through decomposition of water (H2O), and hydroxide ions (OH-) meet sodium ions (Na+) to form caustic soda (NaOH). The reaction that generates occurs occurs. Chlorine gas (Cl2) generated by the electrode reaction and caustic soda (NaOH) react to produce sodium hypochlorite (NaClO).

On the other hand, the odor treatment device known as a scrubber is one of the gas-liquid contact type dust collectors, and is also referred to as a cleaning dust collector.If droplets are sprayed into the gas to give a large velocity difference between the gas and the droplets, they will float in the gas. The particles are trapped by colliding with droplets by an inertial force, and since specific gas components as well as particles can be absorbed and removed by the liquid, they are generally used for the treatment of odors in gases. In scrubbers, electrolytic chlorine is often used as electrolytic oxidized water for odor treatment.

It is a valve that opens or closes for The sixth valve V6 operates in connection with the electrolyzer pump 160.

Subsequently, referring to FIG. 3 together with FIG. 1, the oxidizing agent filling process in the oxidizing agent generating system of the present invention will be described. In the oxidant filling process, the 4-1 valve (V4a) is switched to the first state, the 4-2 valve (V4b) is switched to the third state, and the seventh valve (V7) is switched to the fifth state. The eighth valve V8 is opened and the sixth valve V6 is closed. With respect to the operations of the fourth valves V4a and V4b and the seventh valve V7, in FIG. 3, it is indicated as ON, which means an open state, and among the open states, in particular, the first state, the third state, and It means having a fifth state. In addition, the closed state of the sixth valve V6 was indicated as OFF. In the oxidant filling process in the oxidant generation system of the present invention, the two electrolyzers 140a and 140b receive salt water whose concentration is adjusted through passages L23a and L23b, respectively, to generate an oxidizing agent through electrolysis to generate an oxidizing agent through passages L24a and L23b. This is a process of charging the oxidizing agent generated in the oxidizing agent storage tank 150 through L24b. As a result of the two electrolyzers independently generating oxidizing agent through electrolysis, the oxidizing agent can be quickly charged.

Subsequently, with reference to FIG. 4 together with FIG. 1, the continuous supply process in the oxidizing agent generation system of this invention is demonstrated. In the continuous supply process, the 4-1 valve (V4a) is switched to the second state, the 4-2 valve (V4b) is switched to the fourth state, and the seventh valve (V7) is switched to the sixth state, , The eighth valve V8 and the sixth valve V6 are closed. Similarly, with respect to the operation of the fourth valve (V4a, V4b) and the seventh valve (V7), it is indicated as ON in FIG. 4, which means an open state, and among the open states, in particular, the second state and the fourth state, respectively. , And means having a sixth state. In addition, the closed state of the eighth valve V8 and the sixth valve V6 was indicated as OFF. First, the salt water F3 and F8 passing through the 4-1 valve V4a are electrolyzed in the first electrolyzer 140a to generate an oxidizing agent, and the oxidizing agent generated in the first electrolyzer 140a is the seventh valve. It passes through (V7) (F4) and is stored in the oxidant storage tank (150). In addition, some of the oxidizing agent generated in the first electrolyzer 140a passes through the seventh valve V7, which is a 3-way valve, is pumped by the circulation pump P1, and is supplied to the second electrolyzer 140b ( F6) It is electrolyzed again in the second electrolyzer 140b to generate a high concentration of oxidizing agent. The generated fluid containing the high concentration of the oxidizing agent passes through the 4-2 valve V4b, is transferred to the 4-1 valve V4a (F7), and is again supplied to the first electrolyzer 140a (F8). As a result, the high-concentration oxidizing agent is stored in the oxidizing agent storage tank 150 (F4). In this way, by switching the flow path through appropriate opening or closing of the valves V4a, V4b, V7, V8, the two electrolyzers 140a and 140b are passed in series to generate a high concentration of oxidizing agent, and the oxidizing agent storage tank 150 ) Can be charged. That is, in the oxidizing agent generating system of the present invention, the concentration of the oxidizing agent stored in the oxidizing agent storage diagram can be increased by connecting the two electrolyzers in series through a continuous supply process and switching the flow path so that electrolysis is continuously performed.

Subsequently, with reference to FIG. 5 together with FIG. 1, the circulation process in the oxidizing agent generation system of this invention is demonstrated. In the circulation process, the 4-1 valve V4a and the 4-2 valve V4b are closed (OFF). In addition, the seventh valve V7 is also closed (OFF). Since only the eighth valve V8 and the sixth valve V6 are opened (ON), the oxidizing agent stored in the oxidizing agent storage tank 150 by the electrolyzer pump 160 is supplied to the second electrolyzer 140b and then the second electrolyzer ( It is electrolyzed in 140b) and supplied to the oxidizing agent storage tank 150 through the flow path L24b. In this way, it is possible to maintain a certain level of concentration by increasing the concentration of the oxidizing agent which is naturally lowered due to impurities during use in the oxidizing agent storage tank. As described above, since the concentration of the oxidizing agent stored in the oxidizing agent storage tank 150 naturally decreases or when it is used in a scrubber (not shown), the concentration decreases due to contamination. It's fair. In the circulation process for maintaining the concentration, first, the oxidizing agent stored in the oxidizing agent storage tank 150 is transferred to the oxidizing agent line (L41, L42, L43) through the opening (ON) of the sixth valve (V6) and the operation of the electrolyzer pump (160). It is transferred through (F9), flows back into the second electrolyzer (140b) through the 4-2 valve (V4b) (F10), and the electrolyzer (140b) electrolyzes it again and supplies it to the oxidant storage tank (150). It is a step of (F11). The concentration of the oxidizing agent stored in the oxidizing agent storage tank 150 is kept constant by increasing the concentration of the contaminated and diluted oxidizing agent again to an appropriate concentration through this circulation process. In addition, since a large-capacity electrolyzer is not necessary in such a circulating process, the life of components (eg, electrodes) in the electrolyzer can be extended by operating only the second electrolyzer 140b.

Referring back to Fig. 1, the oxidizing agent generation system according to an embodiment of the present invention is opened or closed so that the concentration of the oxidizing agent stored in the oxidizing agent storage tank 150 can be adjusted as needed by directly supplying time water to the oxidizing agent storage tank 150. It may further include a second valve (V2). Since the second valve (V2) is opened to directly supply water, it is a valve used to lower the concentration of the oxidizing agent in the oxidizing agent storage tank (150).

In addition, it may further include a fifth valve (V5) that is opened or closed to directly supply the salt water concentration-controlled through the second flow meter (M2) to the oxidant storage tank (150). By opening the fifth valve V5, chlorine can be replenished in a circulation process or a continuous supply process by replenishing the salt water whose concentration is adjusted in the oxidizing agent storage tank 150 if necessary.

In addition, although not shown in FIG. 1, a chlorine sensor (not shown) may be further provided as a component for checking the concentration of the oxidizing agent generated by measuring effective chlorine by being installed on the line L24.
