Description

Deodorizer tower for sewer pipe

The present invention relates to a deodorization tower, and more particularly, to a deodorization tower installed in a sewer near a sewage treatment plant to remove odors of sewage.

The sewage treatment plant improves the water quality of the local rivers and coasts by optimally treating and discharging wastewater generated in each area, and it is a facility to comfortably create the living environment of the citizens. It is also called the terminal treatment plant.

Sewage is sewage generated from daily life and consists of sewage and stormwater. Sewage is collected from household sewage, drainage from factories and workplaces, ground water, etc., and stormwater is gathered through drainage lines such as roads. The main sources of sewage are household wastewater (toilet, kitchen sink, bathtub, etc.), road drainage (drainage on the streets such as rainwater and groundwater), school wastewater (drainage, toilet, sewage etc.) and factory wastewater.

Sewage treatment plants treat sewage using chemical methods or microorganisms, apply advanced treatment methods to remove nitrogen and phosphorus, and operate advanced sewage management systems to improve the discharge water quality. Sewage treatment plants generally operate on a large scale in public institutions or municipalities, but in some cases, they operate on a small scale in industrial complexes and remote residential areas.

As a public facility, the sewage treatment plant is a major environmental asset that is essential for the people's daily life. However, due to the nature of the sewage treatment, it is not only neglected by the residents due to the odor generated in the wastewater, There is no problem with the problem. The odor itself is not physically harmful, but it causes serious mental stress to the residents in the surrounding facilities and causes property damage by lowering the quality of the living environment and lowering the real estate price.

It is possible to temporarily reduce odor pollutants by removing periodic dirt such as sludge in order to remove the odor generated in the sewage treatment plant, but there is a disadvantage that the cost increase due to the mobilization of manpower or equipment and the practical odor reduction effect are inferior.

On the other hand, a large deodorization system can be introduced to remove odors. For example, there is known a deodorization apparatus in which a cleaning liquid is sprayed to a deodorization section and a malodorous gas is supplied from the lower part to bring the cleaning liquid into contact with a malodorous gas (JP 10-0966737, registered patent 10-0989563). Also, in some cases, activated carbon is installed in the deodorizer to remove odors. These existing systems have disadvantages in that they are costly to remove smells from ammonia, hydrogen sulfide, etc., which are generated in the sewage treatment plant, after using the explosive medicine or water in the washing tower or passing the activated carbon. Which may cause equipment erosion and secondary environmental pollution.

In addition, existing sewage treatment plants can cause difficulties in management due to waste of budget and increase in management cost when a large number of large-scale deodorization machines are installed with budgets ranging from billions to tens of billions to remove odors.

Especially, the conventional deodorizing device has a large scale, and it is disadvantageous in that it is difficult to apply it to a small-scale odor-inducing company or an animal husbandry business due to a large cost when introducing the facility.

The present invention has been made in view of the above technical background, and an object of the present invention is to provide a new deodorizing tower which is installed in a sewer pipe to remove odors easily in a sewage treatment plant.

Another object of the present invention is to provide a deodorizing tower which is easy to install, easy to maintain and easy to replace with a deodorant.

Another object of the present invention is to provide a deodorizing tower capable of eliminating odors of wastewater by being applied to a large sewage treatment plant, a local unit or a factory unit.

Other objects and technical features of the present invention will be more specifically described in the following detailed description.

In order to attain the above object, the present invention provides a deodorization apparatus comprising: a deodorization tower main body having an open top and a bottom, a pipe-shaped deodorization tower main body, a ventilator mounted on the top of the deodorization tower main body, A first deodorizing section having different multi-stage deodorizing meshes stacked thereon; and a second deodorizing section disposed above the first deodorizing section in the deodorization tower main body, the multi-stage solid deodorant including an acidic deodorant and a basic deodorant, And a cover covering the inlet. The lower end of the deodorization tower body is inserted into a sewer pipe, and the odor generating gas generated from the wastewater flowing through the sewer pipe is introduced into the deodorization tower through the deodorization tower, The deodorant mesh of the first deodorized portion is coated with activated carbon and a mineral , And two or more odorless meshes having different mesh sizes are stacked at intervals of 1 to 5 cm apart from each other, and the multi-stage solid deodorizer of the second deodorizer is stacked with two or more layers spaced apart by 5 to 20 cm And a deodorizing tower for a sewer pipe.

In the present invention, it is preferable that the solid deodorant of the second deodorization portion is laminated inside the deodorization tower while being contained in a cartridge having a structure whose surface is opened.

Further, the present invention is characterized in that measurement openings are formed in the upper and lower side faces of the deodorization tower body, respectively, so that odor due to noxious gas is reduced through the deodorization tower, while exchange of the first and second deodorizations Period can be monitored periodically.

According to the present invention, odor generated in wastewater or the like can be easily removed by being installed in a sewer pipe. Therefore, it is possible to improve the odor generation situation caused by wastewater such as sewage flowing into the sewage treatment plant, and it is possible to fundamentally solve the environmental complaint problem of the odorous area. The deodorizing tower of the present invention is easy to install, easy to maintain, easy to replace, and can be applied to a large sewage treatment plant as well as a local sewage treatment plant to remove the odor of wastewater.

The present invention proposes a deodorizing tower for removing odors for a sewer near a sewage treatment plant.

The sewer pipe is a drainage pipe for collecting sewage and stormwater and transporting it to the sewage treatment plant and the discharge area, and is a means for moving the sewage water flowing into the sewage treatment plant or the purified water discharged from the sewage treatment plant.

The amount of dissolved oxygen is lowered due to the action of various bacteria and the internal pressure and odor caused by various harmful gases such as hydrogen sulfide, ammonia and methane are generated in the sewage pipes flowing in various domestic sewage and industrial wastewater. It is easy to install a simple deodorizing tower which is efficiently reduced.

Conventional deodorizing towers have been used as a means of reducing odor disposed inside, and a simple cleaning tower method using an adsorbent and a liquid deodorant have been utilized, but they have not been utilized properly due to operational expenses and management problems. Especially, they are installed in sewer pipes It is not easy to do.

The present invention can reduce the odor of the sewage treatment plant by dispersing the pressure inside the sewer pipe and eliminating the odor caused by the harmful gas, thereby eliminating the environmental complaints that may be generated in private houses and various commercial facilities around the sewage treatment plant . In particular, by introducing a dual structure deodorization system in which a deodorization tower is structured in a multi-stage and a solid deodorant is installed in a multi-stage structure, the adsorption and neutralization of odor generating substances Thereby maximizing the deodorization efficiency.

1 shows a deodorization tower for a sewer pipe according to a preferred embodiment of the present invention. The deodorization tower 100 includes a first deodorization unit 113 and a second deodorization unit 114 installed in the deodorization tower body 110 and the deodorization tower body with an upper end 111 and a lower end 112 opened, .

A ventilator 120 is mounted on the upper end 111 of the deodorization tower main body to discharge the air inside the deodorization tower main body through the upper end of the main body according to the external air flow.

The lower end 112 of the deodorization tower body is inserted below the ground surface 210 so as to be interlocked with the sewer pipe 200. The odor generating gas generated in the sewage flowing through the sewer pipe flows into the first deodorizing unit and the second deodorizing unit of the deodorization tower body through the lower end of the deodorization tower main body and is discharged through the upper end of the deodorization tower through the deodorization tower . In the case of a sewer pipe installed below the earth surface, the ground surface may be tapped at a certain depth and a part of the sewer pipe may be connected to an auxiliary pipe (not shown) to be connected to the bottom of the deodorizing tower. After completing the installation of the auxiliary pipe connected to the ter- minator and the sewage pipe, it is possible to complete the construction by filling the ter- rough base surface 150 with concrete or the like and then connecting the auxiliary pipe and the deodorizing tower main body.

Preferably, the first deodorizing unit 113 installed in the deodorization tower main body has multi-stage deodorization meshes having different mesh sizes stacked, and the second deodorization unit 114 is disposed inside the deodorization tower main body, It is preferable that a multi-stage solid deodorant, which is provided above the deodorization section and includes an acidic deodorant and a basic deodorant, is laminated.

In the present invention, as shown in FIG. 2, a deodorant inlet port such as a deodorant mesh or a solid deodorant to be inserted into the first deodorant and the second deodorant is formed on the side of the deodorizer main body to insert the deodorant mesh and the solid deodorant, Make periodic exchanges possible. In addition, it is preferable that the cover includes a cover (113a, 114a) for covering the insertion port so as to prevent the bad odor flowing through the deodorization tower body from being seized to the outside during the purification process.

In addition, the present invention is characterized in that measurement openings (115a, 115b) are formed on the upper and lower side faces of the deodorization tower main body, respectively, so that odor due to noxious gas is reduced through the deodorization tower, So that the replacement time of the first deodorizing unit and the second deodorizing unit can be periodically monitored.

In the present invention, the first deodorizing unit may be used by laminating a deodorant mesh coated with activated carbon and a mineral in multiple stages. In the case of a commercialized deodorant mesh, the polyester plain weave is coated with vinyl chloride resin and two types of deodorant (for example, activated carbon and natural mineral) are inserted, and the odor adsorbs and decomposes on contact with the surface. Odor absorption by activated carbon and degradation of odor of mineral are reduced, and water washing is also possible. In the present invention, such a deodorant mesh is stacked such that two or more deodorant meshes having different mesh sizes are spaced apart from each other by a distance of 1 cm to 5 cm, so that odor reduction efficiency as well as air flow is smooth.

Also, in the present invention, the multi-stage solid deodorant of the second deodorizer is stacked so that two or more layers are spaced apart from each other by a distance of 5 to 20 cm, so that the odor reduction can efficiently proceed and air flow is smooth. In the case of a solid deodorant, it is preferable to use an environmentally friendly deodorizing action by using a natural substance and a microorganism unlike a conventional fragrance or chemical deodorant which depends on a masking effect. For example, a liquid deodorizing solution may be prepared by mixing a microorganism culture solution with a vinegar solution, a herb, a seaweed, etc., and then further adding a basic solution or an acidic solution, followed by solidifying by mixing a gelling agent such as agar or gelatin. It can be used as a basic deodorant or an acidic deodorant by controlling the components to be mixed, and it is also possible to use a commercially available product. By using the solid deodorant, it is easy to stack the multi-stage deodorant, and it is difficult to finely spray in the existing liquid deodorization system and the cost increase due to the liquid spray amount can be solved.

In the present invention, it is preferable that the solid deodorant of the second deodorization portion is laminated inside the deodorization tower while being contained in a cartridge having a structure whose surface is opened. The cartridge container of the open structure is easy to remove odorous substances flowing through the deodorization tower main body while preventing the shape of the solid deodorant from changing, and it is easy to replace and stack solid deodorant.

The first deodorizing unit and the second deodorizing unit of the deodorizing tower body are provided with a mesh-type shelf arranged at an interval to facilitate the insertion and arrangement of the deodorant mesh and solid deodorant stacked in the first deodorizing unit and the second deodorizing unit, It can be inserted and fixed. FIG. 3 shows such a net-shaped shelf. It can be seen that the sides of the deodorization tower body corresponding to the first and second deodorized portions are opened, and the metal mesh-type shelves are provided with intervals therebetween.

Such a separated laminated structure allows the first deodorizing unit and the second deodorizing unit to efficiently perform odor removal activities, respectively, while eliminating the need for separate power for inducing the air flow. In the case of the conventional activated carbon adsorption method, the deodorization efficiency is good due to the pores of the activated carbon provided at the initial stage in the initial stage of installation, but the efficiency may drop rapidly in a short period of time due to the clogging of the pores due to moisture and dust coming from the sewage pipe. On the other hand, in the case of the deodorization tower of the present invention, the first deodorization section and the second deodorization section are spaced apart from each other in the deodorization tower main body, so that the flow of air can be smoothly performed only by the non-dynamic ventrotor rotation force, The increase in cost can be prevented.

Example  - Deodorant With mesh  Solid deodorant multi-stage Laminated Deodorizing tower

As shown in Fig. 4, three deodorizing mesh 130 and three-stage solid deodorant 140 are provided as a first deodorant in the pipe type deodorization tower.

The first deodorizing unit at the lower end was installed so that one layer of deodorant mesh 130a having a mesh size of 0.5 mm and two layers of 2 mm deodorant mesh were spaced apart from each other by 5 cm. The odor generated from the sewer is passed through the deodorization tower through the deodorization mesh layer, and foreign substances such as dust are blocked, anion is generated, and odor molecules are adsorbed. In the case of a commercialized deodorant mesh, the odor reduction can be reduced by about 2 years. However, in order to maximize the function of the deodorization mesh of the deodorization tower, it can be cleaned once a month, for example, or can be installed in a period of 2 to 3 months.

The solid deodorants 140a, 140b and 140c of the second deodorizing section were placed in a cartridge container with a distance of 10 cm from each other. As a solid deodorizer, a ferrous acid gel type commercial deodorizer which improves the odor removal efficiency by stirring high ionized calcium in an organic acid producing microorganism culture liquid was used. Even if the odor molecules are not in direct contact with the deodorant, the odor can be removed by the vaporized gas component from the solid deodorant. As shown in the photograph of FIG. 5, So that the effect of reducing the odor is maximized. A total of 9 pieces of solid deodorant (120g) were installed in each of the three compartments in each of the compartments. The bottom compartment was equipped with a basic deodorizer and the upper compartment was equipped with an acidic deodorizer.

Since the durability of the solid deodorant varies depending on the size, temperature, humidity and air volume of the product, it is preferable to replace the solid deodorant periodically, for example, once every one month to three months, to maintain proper odor reduction capability.

Since the six deodorizing layers of the first deodorizing portion and the second deodorizing portion are spaced apart from each other and composed of a mesh, a meshed lathe, an opened cartridge and the like, the flow of air moving inside the deodorizing tower is small, The ventilation of the air was smooth by only the ventilator of 300 mm, and the separate electric power unit was not necessary.

The odor reduction activity as shown in Fig. 6 was performed through the installed deodorizing tower, and the odor was not detected in the purified air discharged through the ventilator. As a result of measuring the degree of reduction of odor through the bottom of the deodorization tower through the measuring port, it was confirmed that the offensive odor was reduced by 80% or more on average by removing organic matter, ammonia, acidic nitrogen and hydrogen sulfide generated in the sewer pipe .

7 shows a deodorizing tower temporarily installed in a sewer pipe connected to a sewage treatment plant. The inside of the deodorizing tower was checked for the degree of reduction of the odor during the two months after the installation while keeping the security so that the third party could not confirm it. It was confirmed that the convenience of living could be improved by improving the odor generation before the deodorizing tower installation, and it was confirmed that the deodorant can maintain the same deodorizing performance as the first deodorant when it is periodically exchanged. The deodorization tower for a sewer pipe according to the present invention can be easily installed in a sewer pipe such as a sewage pipe connected to a large sewage treatment plant or a factory where a lot of odor generating substances are generated and a wastewater generating plant to generate odorous substances, It is expected to be able to do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Modified, modified, or improved.
