The present invention relates to a method for deodorizing a malodorous gas containing odor components such as ammonia, hydrogen sulfide, methyl mercaptan, trimethylamine, and methyl sulfide.Objects of the present invention are to have a simple configuration, less labor for operation, and a treatment method that is efficient. An object of the present invention is to provide a method for deodorizing gas with a high degree of odor. We live in an environment without ``smell'' every day, but with the recent diversification of lifestyles and overcrowding, we have become increasingly aware of ``smell.'' There are many types of ``smells'', including pleasant ``smells'' such as the scent of flowers, and unpleasant ``smells'' such as rotten odors. Once complaints about ``smell'' become apparent, it becomes a bad odor pollution. In order to eliminate the ``smell'', it is sufficient to remove the foul-smelling substance at the depth at which the ``smell'' is generated, but the source of the foul odor cannot be easily eliminated due to quantity, quality, and structural reasons. For deodorization, there are advantages and disadvantages as shown in Table 1, taking into account the situation of the source, the type, concentration, composition, etc. of the target gas. Based on these facts, we conducted intensive research with the aim of developing an all-purpose deodorizing method, and as a result, we discovered that tannins have a revolutionary effect compared to deodorizing agents. Tannin, also called tannic acid, is a general term for substances belonging to glucosides that are widely present in the plant kingdom. Gallic tannin is mainly composed of five molecules of gallic acid bonded to glucose by an ester bond, and five-fold tannin is m-
The main component is 5 molecules of digallic acid linked to glucose by ester bond. m-digallic acid H Fivefold tannin Tannin is produced by extracting fivefold tannin with boiling water, and has a pale yellow powder, astringent taste, and is soluble in water, alcohol, and glycerin, and binds to proteins and is insoluble in water. Change into matter. Taking advantage of this property, it is used in leather processing, medicine, and as a mordant. Research has revealed that when such tannins are dissolved in water and made into fine droplets and sprayed into foul-smelling gas, various odor components react with each other in the gas phase to deodorize the tannins. Tannins effectively deodorize various odor components such as ammonia and hydrogen sulfide, but in particular, tannins effectively deodorize odor components associated with protein denaturation, such as cigarette tar, smoke during meat processing, and the odor from the production of fishmilk. Although it has the property of reacting with odor components in the form of an aqueous solution, it is not highly reactive, and its properties cannot be fully demonstrated by showering an aqueous tannin solution using a washing tower or the like. In order to increase the reactivity of tannins, it is preferable to form an aqueous tannin solution into ultrafine particles and spray them into the odor gas, and the finer the particle size, the better. However, in this type of spray treatment in the form of ultrafine particles, it is difficult to capture the reaction products after treatment, and tannins in particular may be accompanied by an astringent odor peculiar to tannins depending on the type of raw material, or may be accompanied by iron-like substances. There were problems in terms of practical application, such as reaction with other substances and turning black. The inventor of the present invention was fascinated by the excellent deodorizing effect of tannins, and in light of the problems mentioned above in putting tannins into practical use, as a result of intensive research on methods for capturing tannins, the inventors discovered that they were able to obtain the ultrafine particle state. The floating tannin aqueous solution is easily captured electrically by introducing it into an electrostatic region where a high voltage is applied between two electrodes, positive and negative, causing corona discharge. One of the aims of this project is to improve the effectiveness by developing a capturing means using an electrical method. The outline of this invention is as follows. First, the principle of this invention is a deodorizing agent for treating malodorous gases.
- Spraying an aqueous tannin solution in the form of ultrafine particles into a foul-smelling gas to cause various odor components to react with the tannins. Furthermore, by introducing the treated gas into an electrostatic region where a high voltage is applied between two electrodes (plus and minus) to cause corona discharge, reaction products with odorous substances and fine particles are removed. Electrically captures floating particles of tannin aqueous solution. The feature is that these series of processes are combined in stages. That is, the gist of the structure of this invention is as follows: An aqueous solution of tannin is sprayed in the form of fine droplets into a gas containing odor components such as trimethylamine and methyl sulfide, and the odor components are converted into tannins by the following operation. After the reaction, this reaction gas is introduced into an electrostatic discharge region that generates an electrical corona discharge, thereby collecting the reactants with tannin contained in the gas and fine droplets of excess tannin aqueous solution. A deodorizing treatment method characterized by quickly removing odor components. Next, the principle and effect of the present invention will be explained. First, an aqueous tannin solution is used as a deodorizing agent. Tannin is a natural product related to depsides, and is a general term for substances belonging to a type of glucoside that produce polyphenolic acids and glucose when hydrolyzed. The deodorizing effect of tannins is not clear, but it is speculated that the numerous hydroxyl and carbosyl groups contained in tannins react with various odor components and are inactivated. There are various odor components that react with tannins, and it is difficult to quantify the amount of the reaction, but ammonia, hydrogen sulfide, methyl sulfide, trimethylamine, methyl mercapkun, etc. react well, and acrolein, styrene, pyridine, chlorpicrin, It also reacts with BTX, formaldehyde, etc., and its reactivity is extremely strong. In order to fully utilize the reaction ability of such highly reactive tannins, it is best to make them into an aqueous solution and then react them in the form of fine droplets, or to spray them into a foul-smelling gas in the form of an atomizer. The particle size of the aqueous tannin solution sprayed into the foul-smelling gas is preferably 10 μm or less, ideally 1 μm or less, based on the results of various experiments. Methods for spraying an aqueous tannin solution include pressurizing the aqueous tannin solution with a pressure pump and forcibly atomizing it through a thin nozzle, atomizing method using steam, compressed air, etc., and using ultrasonic waves. An ultrasonic atomization method for atomization can be used. Odor components that are deodorized by an aqueous tannin solution include ammonia, hydrogen sulfide, methyl mercaptan, trimethylamine, methyl sulfide, aromatics, hydrocarbons, fatty acids, amino acids, alcohols, aldehydes, and many other substances. is processed. Further, the concentration of the odor component to be treated can be applied over a wide range from several tens to several tens of thousands of units in terms of odor concentration. Substances that cause odors are inactivated by reactions with tannins, but in order to completely remove odors, it is necessary to remove the reactants with tannins from the gas. Although it is difficult to remove the reaction product and tannin aqueous solution floating in the form of fine particles from the gas, they can be easily captured by the following method. In this method, the treated gas is electrically captured by introducing it into an electrostatic region where a high voltage is applied between two electrodes, positive and negative, causing corona discharge. It is something to be taken. In other words, as shown in Figure 3, the negative ions generated by the corona discharge of the discharge electrodes (positive and negative electrodes) adhere to the tannin aqueous solution mist and its reaction products (mist particles), and the mist particles are charged with negative ions. death,
After it becomes electrically easy to combine with positive ions, it is attracted to the dust collection electrode side by electric force and collected. The velocity component (W) at which the mist particles charged with negative ions move toward the dust collection electrode at this time is theoretically expressed by the following equation. W=K.

[) As understood from this equation, the ability to collect mist by electric force is proportional to the amount of charge and the strength of the dust-collecting electric field, and inversely proportional to the mist particle size. These charge amounts and dust collection electric field strengths are calculated experimentally by taking into consideration the mist particle size to be collected. Next, the configuration of the present invention will be explained using examples. FIG. 1 shows the structure of the present invention in a simplified form of 70 sheets. In the figure, A indicates the malodorous gas to be treated, and B indicates the treated deodorizing gas. In this series of steps from A to B, first, malodorous gas A is sent into the introduction pipe 2 by the blower 1. An atomizer 4 is attached to the inside of the introduction pipe 2, and the chemical solution is supplied to the tank 4 and is atomized by an air port that is force-fed from the compressor 3, and is sprayed onto the foul-smelling gas introduced into the introduction pipe 2. Through this operation, the odor components in the foul-smelling gas are adsorbed by the mist droplets of the aqueous tannin solution. By applying a high voltage between , b and causing corona discharge, the aqueous tannin solution (fog droplets) in the air-fuel mixture is charged and attached to the dust pole, where it is captured. The captured aqueous tannin solution becomes large droplets, collects at the bottom of the electrostatic precipitator 8 through the dust collecting electrode, and is returned to the chemical tank 6 through the drain pipe 10. Through a series of these processes, the foul-smelling gas is completely deodorized and exhausted from the exhaust duct 9 to the outside of the system. Next, embodiments of the invention will be described. Example (1) Tobacco leaves are produced in a drying area where hot air is dried (
2) The amount of malodorous gas sucked was about 10 Nm3ymin, and the gas temperature was about 45-52°C. (3) The aqueous tannin solution sprayed into the foul-smelling gas was tannin diluted 500 times with clear water. (4) A pneumatic atomizer is used to spray the tannin aqueous solution at a rate of approximately 5 kg/cn? 0.1~ by G compressed air
The 05μ solution was sprayed into the malodorous gas. The operating conditions were as shown in Table 2. (6) Table 3 shows the results of measuring the raw gas concentration and the concentration after treatment of the malodorous gas treated by the above method.
