Description

Deodorant Manufacturing Method for deodorizing the space}

The present invention relates to a method for manufacturing a dos deodorant for space deodorization, and in particular, in the case of deodorizing by spraying fine droplets in a space, harmful gases including chlorine gas in the process of manufacturing a deodorant used to more effectively remove a source of odor. It relates to a method for producing a dose deodorant for space deodorization capable of suppressing the occurrence of.

The Air Pollution Conservation Act separately stipulates regulations on air pollutants generated at business sites and odors to protect residents' residential life, and odors at each business site are regulated by the'Odor Prevention Act'.

Along with the improvement of living standards, interest in a more comfortable and healthy life (well being) is increasing, so the necessity of developing a new technology for deodorizing odor is required.

Odors are mainly generated in manufacturing plants, livestock facilities, and wastewater treatment plants, of which livestock facilities are the most at 64% (71,423). There are many complaints about odors in the vicinity of these odor generating facilities, and it is a reality that odor regulations are also being strengthened.

It is important to prevent the spread of odors in the space as there is a high risk of odors occurring in a space that is 2km or more enlarged than the source of the odor.

In order to remove such odors, most of the prior art is focused on improving the efficiency of the washing tower, and most of the technologies for deodorization washing and adsorption tower technologies applied to livestock and sewage treatment plants, and biodeodorants are used.

In addition, a deodorant that sterilizes or removes odor is used, and one of these deodorants is hypochlorous acid, which has high sterilizing power.

In the case of such a conventional deodorization method, there is a concern that the facility cost is high and the efficiency is very low due to a low deodorization rate. Existing liquid cleaning and/or bio-deodorizing facilities require a lot of facility cost, high maintenance cost, and have operational problems such as noise.

In addition, various types of deodorants are used to improve the deodorizing effect in the deodorization process, and hypochlorous acid is included among them.

That is, it is desirable to more effectively stay in the space with the odor source for a long time so that the odor source and the deodorant or the odor removing means can contact the odor source for as long as possible. In addition, it is preferable that the spray deodorization method is not a masking method (a method of enclosing the odor source so that odor is not emitted), but a deodorant that is easy to completely remove the odor source from the space.

The deodorization manufacturing system 1600 according to the deodorization manufacturing method according to an embodiment of the present invention, as shown in Fig. 1, is mixed with water and sprayed at high pressure to remove the odor in the required space. (1) step of preparing a dilute hydrochloric acid solution by mixing hydrochloric acid with water (1601, 1610, 1620, 1621, 1622); (2) process of mixing sodium hypochlorite (NaOCl) with water to produce sodium hypochlorite diluted solution (1601, 1611, 1630, 1631, 1632); It is preferable to include a (3) process (1640, 1643, 1645) of preparing hypochlorous acid (HClO) by mixing the sodium hypochlorite diluted solution of the (2) process with the hydrochloric acid diluted solution of the (1) process.

Here, in the step (1), 180 liters of water is mixed at a ratio of 0.57 liters of 35wt% hydrochloric acid (Hcl), and in the step (2), 9w% of sodium hypochlorite (NaOCl) is mixed at a rate of 2.2 liters of 20 liters of water. It is preferred to be mixed.

In general, chlorine gas, which is a harmful gas, is generated in the process of manufacturing hypochlorous acid.

The present invention was derived with a particular focus on this point of view, and the ratio of sodium hypochlorite (NaOCl) and hypochlorous acid (HClO), which is one of the mixed solutions for producing hypochlorous acid, is 50 wt%, rather than producing 100 wt% hypochlorous acid. : It is to be prepared in 50wt%.

First, when hydrochloric acid and sodium hypochlorite are mixed, hypochlorous acid is prepared as follows.

HCl + NaClO -> HClO + NaCl

However, in this process, hydrochloric acid and hypochlorous acid are combined to generate chlorine gas as follows.

HCl + HClO -> H ₂ O + Cl ₂ <Occurrence of chlorine gas>

That is, when sodium hypochlorite (NaClO) is 100% for the first time, chlorine gas is not generated, but when HCl is continuously injected, the ratio of NaClO decreases due to mutual reaction, and when the ratio of HClO increases, chlorine gas is generated.

Accordingly, the method of manufacturing a deodorant according to the present invention is a method of preparing hypochlorous acid (HClO) by slowly injecting and reacting the diluted hydrochloric acid diluent while injecting the diluted sodium hypochlorite mixture into the hypochlorous acid mixing tank 1640. In this process, the pH is adjusted for the same reason as described later.

When the ratio of sodium hypochlorite (NaClO) and hypochlorous acid (HClO) is 100:0 (about PH11), chlorine gas is not generated even when hydrochloric acid (HCl) is injected and reacted.

On the other hand, from when the ratio of sodium hypochlorite (NaClO) and hypochlorous acid (HClO) is 50:50 (about pH8), when hydrochloric acid (HCl) is injected, hydrochloric acid and hypochlorous acid (HClO) react to generate chlorine gas. The probability increases dramatically.

In addition, in order to react both sodium hypochlorite (NaClO) and hypochlorous acid (HClO) at a ratio of 0:100 (about PH5), deodorization efficiency can be maximized, but chlorine gas is very severe during manufacture.

Accordingly, in the present invention, if the ratio of sodium hypochlorite (NaClO) and hypochlorous acid (HClO) is 50:50 (based on pH 8), the probability of generating chlorine gas can be lowered.

At this time, in order to match the amount of mixed hypochlorous acid (HClO), the amount of sodium hypochlorite (NaClO) is doubled and the ratio of sodium hypochlorite (NaClO) and hypochlorous acid (HClO) is prepared at 100:100. It is preferable to use the method.

That is, if the amount of sodium hypochlorite (NaClO) and hydrochloric acid (HCl) is doubled and a method of producing at a pH of 8 or in the range of pH 6.5 to pH 7 is used, a safer and more effective Dose deodorant can be prepared.

Here, 50wt% of 100wt% of sodium hypochlorite (NaClO) reacts with 50wt% of HCl to become hypochlorous acid, and 50wt% of remaining sodium hypochlorite (NaClO) is mixed with hypochlorous acid and the final product, hypochlorous acid. Therefore, the deodorizing efficiency can be improved more than the deodorant that exists only with hypochlorous acid itself. The present applicant named this deodorant as a tentative name'DOIS: DeOrdor In Space, a space deodorant' deodorant.

On the other hand, a deodorant manufacturing system 1600 for manufacturing hypochlorous acid, which is a deodorant applied to the present invention, is shown in FIG. 1.

First, tap water or purified water is supplied through the water supply pipe 1601. It is preferable that the water supply pipe 1601 includes a flow meter or the like so that a set amount of water can be supplied to the hydrochloric acid solution tank 1610 and the sodium hypochlorite solution tank 1611.

The hydrochloric acid solution tank 1610 and the sodium hypochlorite solution tank 1611 each receive a set amount of water supplied from the water supply pipe 1601. For example, it is preferable that the hydrochloric acid solution tank 1610 accommodates 180 liters in a quantitative amount, and the sodium hypochlorite solution tank 1611 accommodates 20 liters in a quantitative amount.

Next, the water contained in each of the hydrochloric acid tank 1610 and the sodium hypochlorite tank 1611 is transferred or supplied to the hydrochloric acid mixing tank 1622 and the sodium hypochlorite mixing tank 1632 through pipes.

And, to the hydrochloric acid mixing tank 1622, 35wt% of hydrochloric acid stored in the hydrochloric acid storage tank 1620 is supplied by a fixed amount of 0.57 liter through the hydrochloric acid supply pump 1621. 35wt% of hydrochloric acid and water are mixed in a hydrochloric acid mixing tank 1622 through a stirrer or the like.

In addition, to the sodium hypochlorite mixing tank 1632, 9wt% of sodium hypochlorite stored in the sodium hypochlorite storage tank 1630 is supplied by a quantitative 2.2 liter through the sodium hypochlorite supply pump 1631. 9wt% of hydrochloric acid and water are mixed through a stirrer or the like in a sodium hypochlorite mixing tank (1632).

Here, the sodium hypochlorite solution mixed in the sodium hypochlorite mixing tank 1632 is supplied or transferred to the hypochlorous acid mixing tank 1640, and the hydrochloric acid solution mixed in the hydrochloric acid mixing tank 1622 is transferred to the hypochlorous acid mixing tank 1640. The two solutions are mixed in the hypochlorous acid mixing tank 1640 while transferring in the range where the pH value is maintained in the range of 6.5 to 7.

In this process, in the hypochlorous acid mixing tank 1640, the hydrochloric acid solution and the sodium hypochlorite solution react to generate hypochlorous acid. A small amount of gas or gas generated in this process is discharged into the atmosphere through the air filter 1643 and the exhaust fan 1645.

The generated hypochlorous acid is stored in the hypochlorous acid storage tank 1649 through the hypochlorous acid transfer pump 1647. The hypochlorous acid stored in this way may be stored in the deodorant tank 105 as shown in FIG. 2, mixed with water at a concentration set in the water and the water deodorant supply unit 110, and sprayed through the fog nozzle 138.

The deodorant prepared through this process is mixed with material and used in the space deodorization system 100 to be described later.

The space deodorization system 100, as shown in Figure 2, and a water deodorant supply unit 110 for storing by mixing the supplied water and the deodorant; A high pressure is formed in the water in which the deodorant supplied from the water deodorant supply unit 110 is mixed, and fine water droplets in the space required through the high pressure (for example, refer to the washing tower referred to as '153' in FIG. 1) Including, but the size of the droplets generated from the fog nozzle 138 is preferably 1 ~ 30㎛ range.

Here, the deodorant preferably contains hypochlorous acid (HClO).

In addition, the size of the droplet sprayed from the fog nozzle 138 is more preferably in the range of 3 ~ 10㎛.

In addition, the concentration of the deodorant is in the range of 50 to 100 ppm in the case of a closed space including a closed washing tower (not shown), and in the case of a yard space including a yard (see FIG. 5) that is open and has a shielding film. It is preferable to include a range of 10 to 200 ppm.

Here, the hypochlorous acid is preferably prepared by mixing a solution obtained by mixing 0.57 liter of 35 wt% hydrochloric acid (Hcl) in 180 liter of water and a solution mixing 2.2 liter of 9 wt% sodium hypochlorite (NaOCl) in 20 liter of water. Do.

Hereinafter, the space to which the space deodorization system 100 is applied is a fluid flowing along the front end flowing into the cleaning tower 153 as shown in FIG. 5 and the rear end passing through the cleaning tower as shown in FIG. 5 for convenience of explanation. As an example, fine droplets are sprayed from the fog nozzle 138 by the high pressure generated in the high-pressure pump 131. Of course, this space can be applied not only to the cleaning tower 153 of one example, but also to various enclosed spaces.

The water supply pipe 103 serves to supply tap water or purified water as needed to the water deodorant supply unit 110. It is preferable that the water supply pipe 103 has a structure capable of supplying a constant amount set by a flow meter (not shown) or a level sensor (not shown) to the water deodorant supply unit 110.

The deodorant tank 105 functions to store hypochlorous acid, which is a deodorant manufactured by the deodorant manufacturing system 1600 of FIG. 1 to be described later, and the deodorant supply pump 107 is set in the amount of the deodorant stored in the deodorant tank 105. It can be supplied to the water deodorant supply unit 110 in a fixed amount.

The fog generating unit 130 can form the required fine droplets by pressing the liquid mixed with the water and the deodorant supplied from the water deodorant supply unit 110 at high pressure, as shown in FIG. Accordingly, a filter (not shown), a high pressure pump 131, a pressure sensor 132, a bypass valve 133, a relief valve 134, a check valve 135, a drain valve 136, a high pressure pipe 137, and It is preferable to include a fog nozzle 138. The pressure sensor 132 senses the pressure generated by the high pressure pump 131 to control the number of revolutions of the high pressure pump 131 or provides information for opening the bypass valve 133. The bypass valve 133 may recover some of the high-pressure water to the water deodorant supply unit 110 when a higher pressure liquid than a set amount is generated or the operating quantity of the fog nozzle 138 decreases. The relief valve 134, the check valve 135, and the drain valve 136 are known configurations applied to general piping, and detailed descriptions thereof will be omitted.

The high-pressure pump 131 pressurizes the liquid supplied from the water deodorant supply unit 110 to a high pressure, and may be provided in various pump types. The high-pressure pump 131 is a non-shown motor (for example, a DC motor, etc.) rotating by an applied power source in a configuration that boosts the introduced liquid to a high pressure, and a plunger type that generates high pressure in water by the rotational force of the motor. It is preferable to include a high-pressure pump containing. It is more preferable that the high-pressure pump 131 is capable of varying the rotational speed of the motor so that the required flow rate can be adjusted.

The liquid pressurized to a high pressure in the high pressure pump 131 may be sprayed into a predetermined droplet from the fog nozzle 138 coupled to the end of the high pressure pipe 137 through the high pressure pipe 137. The fog nozzle 138 is provided in various sizes, and the average particle size of the sprayed droplets may be different depending on the pressure.

Here, the droplets sprayed from the fog nozzle 138 are finer, the more preferable, but it is not easy to form fine particles, but the'Fine Dust' in Application No. 10-2018-0016935 filed by the applicant on February 12, 2018. Ultrafine droplets for removal, humidification, and deodorization It is even more desirable if the technology related to'cyclone fog air purifier' can form ultrafine droplets. If necessary, the pressure of the fog nozzle 138 and the high pressure pump 131 may be adjusted or selected and used by a control unit (not shown) so as to form very fine droplets.

Here, it is preferable that the size of the droplet sprayed from the fog nozzle 138 is small if possible. That is, the finer the space, the longer the time to stay in the space, and not only can it be evenly dispersed in the space, but also evaporation can occur effectively. Such fine droplets that can stay in the space for a long time come into contact with the odor source, and the deodorant contained in the droplet reacts with the odor source, thereby effectively removing the odor source.

The approximate comparison of the time spent in the space according to the size of the droplet is shown in Table 1 below.

Particle size (㎛) state Time it takes to fall 3m (sec) 5,000~2,000 heavy rain 0.05~0.9 2,000`1,000 Strong rain (spring cooler) 0.9~1.1 1,000~500 Moderate rain 1.1~1.6 500~100 Weak rain 1.6~11 100-50 Micro fog 11~40 50-10 Humid fog 40~1,000 10~2.0 Dry fog 1`020~25,400 1.0~0.01 Smoke fog Floating in the air 0.01 Acting Floating in the air

As shown in the table above, the average particle size of the droplets formed in the fog nozzle 138 according to the present invention is preferably in the range of 1 to 100 µm, preferably in the range of 1 to 30 µm, which takes a long time to stay, more preferably 10 µm. Below.

Here, the space deodorization system 100 may further include an unillustrated odor concentration sensor or an odor source concentration sensor capable of detecting an odor in the space, and the number of rotations of the high pressure pump 131 based on the odor concentration sensor It is also possible to increase the amount of droplets generated from the fog nozzle 138 by increasing.

The amount of droplets sprayed from the fog nozzle 138 per unit volume in the space is referred to as fog hold-up, and as the fog hold-up increases, the number of droplets occupying the space increases, giving an opportunity to contact the odor source. As the degree increases, the odor removal rate increases.

The figure or graph shown in FIG. 3 is an analysis of the size distribution of fog droplets through simulation flow analysis, and the upper figure shows the particle distribution inside the analysis domain 20 seconds after spraying from the fog nozzle 138, ranging from 0 to 7.35 μm. It shows that the particle diameter is distributed. The lower graph of FIG. 3 shows the particle diameter distribution at a distance of 25 cm from the nozzle 20 seconds after spraying from the fog nozzle 138, showing that the particle diameter is distributed in the range of 0 to 10 μm, and the average particle diameter is 3.10 μm.

Here, the deodorizing function is a space deodorizing function capable of neutralizing and removing odors floating in the air while being suspended in the air by spraying water containing a deodorant with the fog nozzle 138. Even in the deodorizing function, the size of the droplets can be reduced and the droplets can be neutralized by binding to fine odor particles that generate odors. In addition, it is desirable to make the size of the droplets fine so as to increase the possibility of collision with odor particles that remain in the space and generate odors by staying in the space for a long time if possible and increase the adhesion reaction.

That is, the odor source floating in the space is adsorbed by the sprayed droplets and prevents spreading or spreading in the air, thereby removing the odor. In this process, hypochlorous acid, which is a deodorant, undergoes a chemical reaction with the odor source to transform the odor source into carbon dioxide and water.

In one test example of such a space deodorization system 100, the fog nozzle 138 is a'front end' through which gas including an odor source flows to the cleaning tower 153 of FIG. 2 (right side of FIG. 2, four fog nozzles). (138)) and the'rear end' through which the gas passing through the cleaning tower 153 flows (the left side of FIG. 2, the eight fog nozzles 138) were installed, respectively.

The capacity of the fog nozzles 138 applied at the time of the actual test as shown in FIG. 2 is 0.2020LPM for each of the front ends (4 units), and 0.0787LPM for each of the rear ends (8 units).

Accordingly, the high pressure pump 131 was set to a capacity of about 1.5 LPM and operated to a pressure of 70 bar.

Here, the supply ratio of the deodorant is set according to a map or program set by the control unit based on the result of the odor concentration sensor, etc. so that the ratio can be set according to the change in the concentration of the odor source, and an appropriate amount from the deodorant supply pump 107 It is preferable to supply 110.

When only the washing tower was operated, the concentration of hydrogen sulfide before and after the washing tower was 6 and 3.6 ppm, respectively, which had the effect of reducing odor by 40%.

When only the space deodorization system 100 according to the present invention was operated, the concentration of hydrogen sulfide before and after the washing tower was 6 and 1.7 ppm, respectively, thereby reducing odor by 72%.

When the cleaning tower (no caustic soda was added) and the space deodorization system 100 according to the present invention were operated simultaneously, the concentration of hydrogen sulfide before and after the cleaning tower was 6 and 1.5 ppm, respectively, thereby reducing odor by 75%.

When the cleaning tower (caustic soda is added) and the space deodorization system 100 according to the present invention were operated at the same time, the concentration of hydrogen sulfide before and after the cleaning tower was 6 and 1.2 ppm, respectively, thereby reducing odor by 80%.

On the other hand, considering that the installation and operation cost of the space deodorization system 100 according to the present invention is less than 1/10 compared to the washing tower, it can be seen that the deodorization method according to the present invention can be evaluated to be very effective.

In addition, when the cleaning tower and the space deodorization system 100 according to the present invention are simultaneously operated, it has been evaluated to be about four times more effective than when only the cleaning tower is operated. Accordingly, it was evaluated that the present invention can be applied alone or the present invention can play an auxiliary role in the operation of the washing tower in order to remove the odor. In particular, it would be very desirable that the present invention serves as an auxiliary role of the washing tower when the odor spreads farther, such as in summer, or when the concentration of the odor source is severe.

Accordingly, according to the present invention, it is possible to provide a method of manufacturing a dois deodorant for space deodorization that can provide a deodorant capable of improving the deodorizing effect of the odor source by mixing with fine droplets in order to increase the possibility of contact with the odor source in the space. have.

In addition, it is possible to provide a method of manufacturing a dos deodorant for space deodorization in which the production process is simple and convenient, and the production equipment cost is low.

In addition, compared with the prior art, it is possible to provide a method for producing a dose deodorant for space deodorization capable of suppressing the generation of harmful chlorine gas during reaction.

On the other hand, the space deodorization system 200 according to another embodiment of the present invention, unlike the above-described embodiment, as shown in the schematic diagram of FIG. 4 and the photograph of FIG. 5, the space is not sealed but is an open space. The storage yard 155 including the filthy yard yard that contains is the target of the deodorization.

Since only the space subject to deodorization is different as an open space, and the overall system is the same as compared with the above-described embodiment, a description of each configuration will be omitted.

Since it is an open yard 155, part of the open space was covered with a screen in order to somewhat reduce the flow of air.

In this embodiment, as shown in FIG. 4, fog nozzles 138 each having a capacity of 0.0787 LPM are arranged in seven rows in one row in the high-pressure pipe 137. Accordingly, the capacity of the high pressure pump 131 was selected to be about 3.9LPM.

In order to verify the performance of the spatial deodorization system 200 according to the present invention, the complex odor was measured according to the air dilution sensory method.

The evaluation method was to compare and analyze the concentration before and after spraying (30 minutes) of the fog nozzle 138 in a state where air flow was minimized by installing a partition wall, and the table is shown in <Table 2>.

division Measure Complex odor (pear) One Before spraying the fog nozzle in the yard 2080 2 After spraying the fog nozzle in the yard 30 Odor removal rate (%) 98.6

[Table 2] shows the performance evaluation results. Before spraying the fog nozzle 138 according to the present invention, the composite odor concentration was 2080 times, but after spraying the fog nozzle 138 for a set time, the composite odor concentration was 30 times. [Table 2] shows that it has decreased.

In addition, in another embodiment of the present invention, unlike the above-described example, the ratio of sodium hypochlorite (NaOCl) and hypochlorous acid (HClO) as a deodorant is preferably expanded from 50:50 to 0:100.

In other words, when the ratio of hypochlorous acid and hypochlorous acid is 50:50, there is an advantage that chlorine gas is not generated, but another effect is that the pH is about 7.5, so it can be deodorized by neutralization reaction of strong acidic odor. In addition, a product with a ratio of hypochlorous acid and hypochlorous acid of 0:100 has a pH of about 5, so it is easy to deodorize odors with strong alkalinity, and has the advantage of excellent sterilization and deodorization decomposition capabilities. That is, it has the advantage of being able to appropriately select a deodorant according to the acidity of the pollutant to be deodorized.

This Dois deodorant is different in that it can be customized to a wide range of odors by controlling the ratio of hypochlorous acid (HClO) from 50% to 100% in the ratio of sodium hypochlorite (NaOCl) and hypochlorous acid (HClO). . In other words, it utilizes the deodorization and sterilization properties of hypochlorous acid, and uses the characteristics of pH adjustment and reduction of chlorine gas generation by sodium hypochlorite.

Accordingly, according to the present invention, it can be seen that it is effective not only in a closed space but also in an open space.

Here, although several embodiments of the present invention have been illustrated and described, those skilled in the art having ordinary knowledge in the technical field to which the present invention pertains will be able to see that the present embodiments can be modified without departing from the principles or spirit of the present invention. will be. The scope of the invention will be determined by the appended claims and their equivalents.
