Description

Electrolytic scrubber with automatic control system {ELECTROLYTIC SCRUBBER WITH AUTOMATIC CONTROL SYSTEM}

The present invention relates to an electrolytic scrubber combined with an automatic control system, and specifically, electrolytic oxidized water is introduced into the scrubber to treat substances that cause odors such as hydrogen sulfide or ammonia (hereinafter abbreviated as 'odor substances'). In supplying, an electrolytic scrubber combined with an automatic control system for automatically controlling operating conditions such as maintaining salt concentration, maintaining oxidation water concentration, and maintaining appropriate water level is provided.

In general, devices that generate electrolytic chlorine (ClO-, HClO, NaClO, NaClO ₂ ) by electrolyzing salt water are widely known. The electrolytic chlorine produced in this way is an oxidizing agent and is widely used in water purification plants, sewage treatment plants, swimming pool sterilization and disinfection devices, and cafeteria food sterilization devices. Briefly looking at the electrolysis reaction in which electrolytic chlorine is generated, chlorine ions (Cl-) are converted to chlorine gas (Cl ₂ ) through an anode reaction in an electrolyzer. The anode reaction is a competing reaction with the oxygen (O ₂ ) generation reaction through water (H ₂ ) decomposition, and its efficiency is determined by the characteristics of the anode electrode, concentration of salt water, and electrolysis method. Meanwhile, during the anode reaction, water (H2O) decomposes at the cathode to produce hydrogen (H2) and hydroxide ion (OH-), and the hydroxide ion (OH-) meets sodium ion (Na+) to form caustic soda (NaOH). A reaction occurs that produces Chlorine gas (Cl ₂ ) generated by the electrode reaction reacts with caustic soda (NaOH) to produce sodium hypochlorite (NaClO).

On the other hand, an odor (or odorous substance) treatment device known as a scrubber is one of the gas-liquid contact type dust collection devices and is also called a cleaning dust collector. It sprays droplets into the gas to create a large speed difference between the gas and the droplets. By using the principle that particles floating in the gas are captured by colliding with the liquid droplet due to inertial force, not only the particles but also specific gas components can be absorbed and removed from the liquid, so it is generally used to treat bad odors in the gas. Electrolytic chlorine is widely used as electrolytic oxidizing water in scrubbers to treat odors.

There are many known devices or systems that generate and store electrolytic oxidation water (oxidizing agent) containing electrolytic chlorine, which is widely used in treatments such as sterilization and disinfection. However, in such conventional electrolytic oxidizing water generating devices or systems, the oxidizing agent is generated and stored in the oxidizing agent storage tank. Not only does it take a long time to charge, but there is a disadvantage that it is not easy to increase or maintain the concentration of the oxidizing agent in the oxidizing agent storage tank. In order to solve these shortcomings, an oxidizing agent generation system that can shorten the oxidizing agent charging time and easily increase or maintain the concentration of the oxidizing agent stored in the oxidizing agent storage tank at a constant level has been developed in Republic of Korea Patent No. 10-2250773 (registered on May 4, 2021). It has been disclosed. However, this oxidizing agent generation system only discloses a technology that rapidly increases the concentration of the oxidizing agent and continuously generates high concentrations of chlorine.

In order to maximize the treatment efficiency of odorous substances by more efficiently managing the electrolytic oxidation water in the electrolytic oxidation water storage tank, the concentration of salt, oxidation water concentration, and water level in the electrolytic oxidation water storage tank are continuously sensed and the electrolytic oxidation water storage tank is operated based on the sensed results. A system capable of automatically controlling the electrolytic oxidation number within the electrolyte is required in the relevant technical field.

Figure 3 is a diagram for explaining the overall operation flow of an electrolytic scrubber combined with an automatic control system according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings. It should be noted that the attached drawings and examples are simplified and illustrated with the intention of helping those skilled in the art understand the present invention.

Referring to Figures 1 and 2, the electrolytic scrubber combined with the automatic control system according to an embodiment of the present invention includes an electrolytic scrubber (10), a first sump tank (20), a second sump tank (30), and an electrolytic tank (40). ), a first sensing unit (S1), a second sensing unit (S2), and an automatic control unit (50).

The electrolytic scrubber 10 converts odorous substances introduced by the blower 1 from an odor generating source (not shown) into electrolytic oxidation water (hereinafter referred to as first electrolytic oxidation water to distinguish it from electrolytic oxidation water in the electrolytic cell). It is a component for treating with (referred to as second electrolytic oxidation water) and discharging the treated gas into the atmosphere through the chimney 12 of the electrolytic scrubber 10. The electrolytic scrubber 10 includes one water injection section 14 and two electrolytic oxidized water injection sections 16 and 18. The water injection section 14 is located above the electrolytic oxidation water injection sections 16 and 18. The electrolytic oxidation water injection sections 16 and 18 spray electrolytic oxidation water (first electrolytic oxidation water) on the odorous substances introduced by the blower 1, thereby dividing the gas containing the odorous substances and the sprayed electrolytic oxidation water (first electrolytic oxidation water). This is a section for processing odorous substances through a reaction caused by collision between droplets of oxidation water. The water injection section 14 is designed to prevent the chlorine gas excessively generated in the electrolyzer 40 from being discharged into the atmosphere through the chimney 12 via the second water collection tank 30, the inside of the electrolytic scrubber 10, and the chimney 12. This is the section where water is sprayed.

The first water collection tank 20 is a component that stores water to be sprayed into the water spray section 14. The first pump PU1 is a component for pumping water to be sprayed toward the water spray section 14 from the first water collection tank 20.

The second water collection tank 30 is a component that stores electrolytic oxidation water (first electrolytic oxidation water) to be sprayed into the electrolytic oxidation water injection sections 16 and 18. The second pump PU2 is a component that stores electrolytic oxidation water injection sections 16 and 18. It is a component for pumping electrolytic oxidized water (first electrolytic oxidized water) to be sprayed toward the side from the second sump 30. In the second sump 30, electrolytic oxidized water ( Second electrolytic oxidation water) is provided, and the electrolytic oxidation water (first electrolytic oxidation water) in the second water collection tank 30 contains contamination treated through collision between liquid droplets in the electrolytic oxidation water injection sections 16 and 18 and odorous substances in the gas. Substances are mixed, and some of them do not circulate toward the electrolyzer 40, but continue to accumulate in the second water collection tank 30. Electrolytic oxidation water (first electrolytic oxidation water) is transferred to the electrolyzer 40 through the circulation pipe (P10). It continues to circulate. The first electrolytic oxidation water and the second electrolytic oxidation water are nothing more than terms used separately to distinguish them in expression, and they continue to circulate through the circulation pipes (P10 and P20) (of course, there is some residence time). ), it can be regarded as substantially the same electrolytic oxidation water. Circulation of electrolytic oxidation water through the circulation pipes (P10, P20) continues while the electrolytic scrubber 10 is operated by the pump (PU10, see FIG. 3). This is done.

The electrolyzer 40 is a component that receives first electrolytic oxidized water from the second sump 30, generates second electrolytic oxidized water through electrolysis, and supplies it back to the second sump. The electrolyzers 40 are provided in pairs, and the pair of electrolyzers 40 may operate alternately at a certain cycle. In Figure 1, reference numeral 45 indicates a specific example consisting of a pair of electrolyzers, that is, two electrolyzers. For example, each electrolyzer can use a 10V 500A rectifier, and the bare skin of the electrode module per electrolyzer is about 6 liters. (L), and the residence time of the circulated electrolytic oxidation water (second electrolytic oxidation water) may be about 0.75 minutes (min). The current density supplied to each electrolyzer may be about 0.03A/cm ² (about 4-5V).

The first sensing unit (S1) is located in the second sump 30, and measures the acidity (pH), oxidation reduction potential (ORP), and electrical conductivity ( EC (Electical Conductivity) and water level are sensed and the sensing results are provided to the automatic control unit (50).

The second sensing unit (S2) is located within the electrolyzer 40, and automatically detects the acidity (pH), oxidation reduction potential (ORP), electrical conductivity (EC), and salinity of the second electrolytic oxidation water within the electrolyzer 40. Sensing results are provided to the control unit 50.

The automatic control unit 50 detects the first electrolyzed oxidized water in the second sump 30 based on the results sensed by the first sensing unit (S1) and the results sensed by the second sensing unit (S2). Automatically controls acidity (pH), oxidation reduction potential (ORP), electrical conductivity (EC), and water level. That is, ultimately, the acidity (pH), oxidation reduction potential (ORP), electrical conductivity (EC), and water level of the first electrolytic oxidized water in the second water collection tank 30 located at the lower part of the electrolytic scrubber 10 are determined by the automatic control unit. It is automatically controlled by (50), and its control is achieved depending on the sensing result by the first sensing unit (S1) or the sensing result by the second sensing unit (S2).

For example, when the oxidation reduction potential (ORP) of the first electrolyzed oxidized water in the second water collection tank 30 is lower than the lower limit of the preset reference value range, the automatic control unit 50 operates the electrode module in the electrolyzer 40 to The second electrolytic oxidized water is generated within (40) and controlled to be supplied to the second water sump. In this state, if the electrode module in the electrolytic cell 40 continues to operate and the second electrolytic oxidized water continues to be generated, excess chlorine gas may be generated and discharged to the chimney 11 through the electrolytic scrubber 10. There is a risk of explosion due to excessive accumulation of hydrogen gas inside (10) or inside the electrolytic cell (40). Therefore, when the oxidation reduction potential (ORP) of the first electrolytic oxidation cell becomes higher than the upper limit of the preset reference value range, the automatic control unit 50 controls to stop the operation of the electrode module in the electrolytic cell 40 to remove excess chlorine gas. It is possible to prevent risks due to the generation or accumulation of excessive minority gas. Control on the side of the automatic control unit 50 may depend only on the oxidation reduction potential (ORP) of the first electrolytic oxidation water in the second water collection tank 30, and the acidity (pH) and electrical conductivity (EC) of the first electrolytic oxidation water. The acidity (pH), oxidation reduction potential (ORP), and electrical conductivity (EC) of the second electrolytic oxidation water in the electrolytic cell 40 may also be comprehensively considered and utilized for control. Additionally, the water level in the second water collection tank 30 may also be considered.

The electrolytic scrubber combined with the automatic control system of the present invention includes a citric acid tank 70 for cleaning the electrode modules in the electrolyzer 40. The citric acid tank 70 supplies about 5% of citric acid to the electrode module within the electrolyzer 40 to clean the electrode module. For example, the electrolyzer 40 is provided in pairs and the pair of electrolyzers 40 are kept at a certain level. When configured to operate alternately in cycles, cleaning using the citric acid tank 70 is performed on the electrode module within the pair of electrolyzers 40 that is not in operation.

The electrolytic scrubber combined with the automatic control system of the present invention includes salt supply units 60 and 62 (see FIG. 3) that supply the first salt solution. This is to replenish the salt as it continues to be consumed little by little during operation of the electrolytic scrubber. The salt supply units (60, 62) include a salt tank (60) that stores and generates a first salt solution (saturated salt solution) by dissolving salt powder in water, and a mixing chamber (64) that stores the salt stored in the salt tank (60). It includes a salt pump 62 for pumping to the side. The mixing chamber 64 is a component for generating a second salt solution lower than the first salt solution by further mixing water with the first salt solution pumped from the salt pump 62. The water stored in the first water tank 20 and the water supplied to the mixing chamber 64 may be, for example, tap water. The start and end of the operation of the salt pump 62 and the opening and closing of the valves FM11 and FM12, including the flow meter in front of the mixing chamber 64, are measured by the electrolyzer 40 by the second sensing unit S2. Depending on the salinity of the second electrolytic oxidation water, it is controlled by the automatic control unit 50. The flow rate measured by the flow meters in the valves FM11 and FM12 including the flow meters can also be referenced in the control by the automatic control unit 50. For example, when the salinity of the second electrolytic oxidized water in the electrolytic cell 40 is lower than the lower limit of the preset reference value range (salinity is measured by the second sensing unit S2), the automatic control unit 50 controls the mixing chamber. The second salt solution is controlled to be supplied into the electrolytic cell (40) from (64). Meanwhile, when the salinity of the second electrolytic oxidation water in the electrolytic tank 40 becomes higher than the preset reference value range, the automatic control unit 50 controls to stop supplying the second salt solution from the mixing chamber 64 into the electrolytic tank 40. do. This salinity control by the automatic controller 50 can be performed by controlling the valves (FM11, FM12, FM21, FM22) including the flow meter.

In addition, the automatic control unit 150 discharges a certain amount (generally about 10%) of the first electrolytic oxidized water in the second sump 30 when the concentration of contaminants in the second sump 30 becomes higher than the preset standard value. After that (see FL11 in FIG. 3), the water is controlled to be recharged. The contaminants in the second sump 30 are collected by flowing downward with the first electrolytic oxidation water when the odor substances introduced by the blower 1 from the odor generating source are treated with the first electrolytic oxidation water, and are collected in the second sump tank ( 30), it is mixed with the first electrolytic oxidized water and accumulated in the second water collection tank 30. The standard value for determining discharge and recharge of a certain amount of water according to the concentration of contaminants accumulated in the second sump 30 may be set in advance in the automatic control unit 150 as the concentration of a specific substance according to the type of odor generating source, The concentration of the specific substance in the second sump 30 is measured and compared with the standard value, and if it is higher than the standard value, a certain amount of water is discharged and then the water is recharged. Alternatively, the water may be recharged using a timer. Depending on the operating time of the scrubber, the method may be controlled to discharge a certain amount of first electrolytic oxidized water and then recharge the water after a certain operating time. The contaminant accumulated in the second water collection tank 30 may be, for example, sulfate, and the cycle of discharging a certain amount may be one day. Therefore, in order to reduce the sulfate accumulated in the first water collection tank 30 once a day, a certain amount of water (generally about 10%) can be discharged and then the water can be recharged. The water to be recharged is, for example, salt water, and the water level is sensed by the first sensing unit (S1) and is recharged until it reaches an appropriate water level. Discharging a certain amount of the first electrolyzed water and recharging the water can be performed by controlling a valve or pump (not shown) in the automatic control unit 150.

Figure 3 is a diagram for explaining the overall operation flow of an electrolytic scrubber combined with an automatic control system according to an embodiment of the present invention. Referring to FIG. 3 together with FIGS. 1 and 2 , the second water collection tank 30 is initially filled with first electrolytic oxidized water and salt water with a concentration of about 3%, and then the electrolytic scrubber 10 begins to operate. When odorous substances flow into the lower part of the electrolytic scrubber (10) through the blower (1), the pollutants that cause the odor are treated by reaction with the electrolytic oxidizing water while passing through the two-stage electrolytic oxidizing water injection sections from the bottom. Afterwards, it accumulates inside the second water collection tank (30) together with the electrolyzed oxidized water, and the water injection section at the top removes the excessively generated chlorine gas, preventing the chlorine gas from being discharged directly into the atmosphere through the chimney. The automatic control unit 50 determines the oxidation-reduction potential (ORP) of the first electrolytic oxidized water in the second sump 30, depending on the oxidation-reduction potential (ORP) measured in the first sensing unit (S1) located in the second sump 30. When ORP) falls below the lower limit of the preset reference value range, the electrode module in the electrolyzer 40 is operated to generate second electrolytic oxidized water in the electrolyzer 40 and is controlled to be supplied to the second sump tank 30. When the oxidation reduction potential (ORP) of the first electrolytic oxidation water in (30) becomes higher than the upper limit of the preset reference value range, the operation of the electrode module in the electrolytic cell 40 is stopped to maintain the oxidation reduction potential (ORP) in a certain range. Control it to do so.

In FIG. 3, reference numerals V11, V12, V13, and V14 denote valves before and after the pump PU10, and are valves on the circulation path of electrolyzed oxidized water. The salt pump 62 consists of two pump units 621 and 622, one (621) for regular use and the other (622) for spare use. The citric acid tank 70 provides citric acid to the electrode module (e.g., 402) in the electrolyzer that is not operating among the pair of electrolyzers to enable cleaning.
