Description

Deodorizing apparatus

The present invention relates to a deodorizing device that deodorizes and exhausts malodorous gas generated in an odor discharge facility. It relates to a deodorizing device that can effectively solve problems caused by living odors by diluting them to the minimum detection value that cannot be detected and exhausting them.

In general, odor refers to an odor that causes discomfort and disgust by gas containing hydrogen sulfide, ammonia, mercaptans, amines, and other irritating substances that stimulate the human sense of smell.

As the economy developed and people's living standards improved, awareness of the seriousness of environmental problems such as air pollution gradually expanded, and as the people's desire for a healthy and comfortable life continued to increase, in Korea, in February 2005, Since then, the Odor Prevention Act has been implemented for the purpose of preventing odors.

In the above odor prevention law, it is stipulated that various odor discharge facilities that cause odor, such as sewage treatment plants, waste treatment plants, livestock excreta treatment plants, and food treatment plants, must comply with specific emission standards for complex odors and designated odor substances. In order to comply with the prescribed emission standards, a deodorizing device with odor treatment technology has been installed and operated.

Currently, various types of physical, chemical and biological technologies are applied to deodorizing devices for odor treatment, and representative examples of these include adsorption methods, chemical cleaning methods, combustion methods, catalytic combustion methods, and biological treatment methods using microorganisms such as biofilters. is being applied

Conventional deodorization devices to which these various technologies are applied are mutually exclusive in various comparison items, such as the effectiveness of odor removal by applied technology and configuration, economic feasibility according to facility costs, material costs, and maintenance costs, and whether secondary pollutants are generated during the deodorization process. It has advantages and disadvantages, and accordingly, a deodorizing device applied alone or two or more technologies is installed and operated depending on the treatment environment or operating conditions of the facility while being able to comply with the emission standards among these technologies. there is a situation

However, despite the fact that the deodorization device is installed and operated in the odor emission facility as described above, despite complying with the emission standards stipulated in the law, the odor felt by people living in the vicinity of the odor emission facility, that is, disputes related to living odor, and There is a problem that complaints are constantly generated.

In other words, although the odor concentration of the gas emitted by the deodorizing device is reduced to meet the emission standards stipulated in the law, it is not a problem at all in law, but in reality, people living in the vicinity of odor emission facilities There are many cases of complaining of discomfort by feeling.

In this case, it is difficult to solve the problem because it is difficult to impose legal sanctions because people are operating in accordance with the legal emission standards in odor emission facilities despite complaints about odors and complaints about inconvenience. There is a problem that only deepens the conflict between the odor emission facility company and the local community.

Therefore, even if it satisfies the legal emission standards, there is a need for a deodorizing device that further reduces odor to the extent that people do not feel the odor, and in particular, a configuration that can be easily applied to an existing installed and operating deodorization device is further required. something to do.

In addition, terms indicating directions such as front, back, left, right, top, bottom, etc. are only used to describe the directions shown and observed in the drawings, and if the directions shown and observed are different, these terms are also It should be understood that this may vary.

In addition, when it is determined that the technical features of the present invention may be unnecessarily obscured as a matter that is already apparent to a person skilled in the art, such as a known function or a known configuration related in principle in describing the embodiments, The explanation will be omitted.

The present invention provides a dilution effect for odor substances and a diffusion effect for odor substances by additionally mixing external air with the treated gas before the treated gas, which has been deodorized through the deodorization process, is exhausted to the atmosphere, thereby meeting the emission standards stipulated by the law. It relates to a deodorizing device that is not only suitable, but can also effectively prevent even life odors that people may feel uncomfortable with.

For this purpose, the deodorizing device of the present invention may include a deodorizing process tower 100 and an outdoor air mixing means 300 as illustrated in FIG. 1 in a large view.

First, the deodorization process tower 100 is a part that performs a deodorization process with respect to the odor gas (G1) introduced from the odor discharge facility.

That is, the odor gas G1 generated in the odor discharge facility passes through the deodorization process tower 100 and undergoes a malodor treatment process.

The deodorization process tower 100 basically includes a vertical top body 110 having a space in which the odor gas G1 is introduced and accommodated, and a stack formed on the upper end of the deodorization process and the processed gas G2 is discharged. (120) and a blower 130 that provides a transfer force for the inflow of the odor gas (G1) and the discharge of the treated gas (G2).

The blower 130 is not particularly limited in type and installation location, etc., based on the flow direction of the gas, it is provided on the front end side of the top body 110 and serves as the deodorizing process tower 100 for the deodorizing gas (G1). It may be at least one of a push type and a pull type provided at the rear end of the top body 110 to pull the odor gas G1 into the deodorizing process tower 100 and suck it in. .

In addition, although not shown in the drawings regardless of the characteristics of the present invention, the deodorization process tower 100 may include various configurations for performing the deodorization process of the malodorous gas G1, but the present invention is limited to a special configuration Without this, components for implementing various conventionally disclosed physical, chemical, or biological odor treatment technologies such as an adsorption method, a chemical cleaning method, a combustion method, a catalytic combustion method, and a biofilter may be widely included.

For example, if the deodorization process is performed by the chemical cleaning method, the deodorization process tower 100 includes a chemical liquid storage tank in which the chemical liquid is stored, a supply pipe for supplying and spraying the chemical liquid into the deodorizing process tower 100, a spray nozzle, a supply pump, It may include various configurations such as a recovery means for recovering the chemical solution.

Such a deodorizing process tower 100 may be already installed and operating in an odor discharge facility, or may be newly installed.

The odor gas (G1) generated in the odor discharge facility is deodorized to meet the emission standards stipulated in the law by the deodorization process being performed while passing through the deodorization process tower 100 described above. When the treated gas G2 is discharged to the atmosphere as it is, problems such as civil complaints due to odors may occur as described above.

Despite the fact that the deodorization process is carried out in accordance with the emission standards stipulated in the law, problems such as civil complaints due to odors occur because of the odor emission standards stipulated in the law and the odor that people actually feel. This is because the minimum detection density is significantly different.

In other words, the permissible emission standards for odors stipulated in the law are merely legal guidelines, and are different from the standards that actually make people feel bad odors. Therefore, even if the exhaust gas is deodorized in accordance with the emission standards, the minimum detection If the concentration of the odor-causing substance is higher than the concentration, the person may feel the odor and complain of discomfort.

Specifically, looking at the emission standards stipulated in the law for each odor-causing substance and the minimum detection concentration of odors announced by the Ministry of Environment, for example, in the case of ammonia, the emission standards are 2 depending on the industrial area and other areas. While it is stipulated to be less than ppm or less than 1 ppm, the minimum detection concentration is 0.1 ppm, which is considerably higher than the minimum detection concentration.

When comparing some odor-causing substances, in the case of hydrogen sulfide, the emission limit is stipulated to be 0.06 ppm or less or 0.02 ppm or less, while the minimum detection concentration is 0.0005 ppm and methyl mercaptane. ), the emission limit is 0.004 ppm or less or 0.002 ppm or less, while the minimum detection concentration is 0.0001 ppm, and in the case of trimethylamine, the emission limit is 0.02 ppm or less or 0.005 ppm or less. On the other hand, the minimum detection concentration is 0.0001 ppm, and in the case of acetaldehyde, the emission limit is 0.1 ppm or less or 0.05 ppm or less, whereas the minimum detection concentration is 0.002 ppm. It can be seen that there is a fairly large difference between the emission limit stipulated in the law and the minimum detectable concentration of odor, which is the same as the rest of the 22 odor causing substances for which the emission limit is stipulated, a large difference from the minimum detectable concentration. there is

As above, since the permissible emission standards stipulated in the law are stipulated to be high by a significant gap compared to the minimum detection concentration at which a person can feel the odor, even if deodorization is made to meet the emission standards through the deodorization process tower 100 The problem is caused by living odor, and therefore, the present invention further includes an outdoor air mixing means 300 in order to solve this problem.

The outdoor air mixing means 300 may be provided in the exhaust passage of the deodorization process tower 100, and mixes the external air (A) with the treated gas (G2) that has undergone the deodorization process while passing through the deodorization process tower 100. It performs the function of exhaust.

That is, the outdoor air mixing means 300 mixes the outside air (A) with the processing gas (G2) so that the odor concentration of the gas exhausted to the atmosphere does not simply satisfy the legal permissible standards but reaches or at least approaches the minimum detection concentration. It is to further reduce the odor concentration of the exhausted gas.

Here, 'odor gas (G1)' as used herein means the original gas generated in the odor emission facility, that is, the gas in the state before the deodorization process, and the 'treated gas (G2)' means the deodorization process tower ( 100) means a gas that has undergone a deodorization process while passing through it, and the 'mixed gas (G3)' may be understood to mean a gas discharged by mixing the external air (A) with the treated gas (G2).

In addition, the exhaust flow path can be referred to as a flow path through which the gas is transported until it is discharged into the atmosphere after the deodorization process in the deodorization process tower 100, and thus the stack 120 of the deodorization process tower 100, the stack ( It may be understood to include an extended exhaust pipe 340 and the like extending from the 120).

Hereinafter, the outdoor air mixing means 300 of the present invention will be described in more detail.

First, a specific first embodiment of the outdoor air mixing means 300 is illustrated in FIGS. 1 to 2 .

As illustrated in the drawings, the outdoor air mixing means 300 according to the first embodiment of the present invention includes an outdoor air supply pipe 310 , an outdoor air injection nozzle 320 , and a blower 330 for supplying outdoor air. can be configured.

The outside air supply pipe 310 may be installed inside the stack 120 of the deodorization process tower 100 , and specifically, may be installed in an annular shape along the inner circumferential surface of the stack 120 .

The outdoor air supply pipe 310 is connected to the blower 330 for supplying outdoor air, and receives external air (A) according to the driving of the blower 330 for supplying outdoor air.

The outdoor air injection nozzles 320 may be formed in plurality and arranged at regular intervals in the outdoor air supply pipe 310 , and perform a function of injecting the external air (A) supplied to the outdoor air supply pipe 310 .

The outdoor air injection nozzle 320 is formed to protrude upward from the outdoor air supply pipe 310 , and preferably, it may protrude upward from the outdoor air supply pipe 310 at an inclined angle.

When the outside air injection nozzle 320 is formed to be inclined at a certain angle in this way, the outside air A1 is injected to form a swirling flow, and accordingly, the top body 110 of the deodorization process tower 100 after going through a deodorization process. The mixing efficiency of the processing gas G2 rising into the stack 120 from the inside and the outside air A sprayed from the outside air injection nozzle 320 can be maximized.

The blower 330 for supplying outdoor air may be provided on the outside of the stack 120 and connected to the outdoor air supply pipe 310 .

As the blower 330 for external air supply is driven, it sucks in the outside air (A) and supplies it to the outside air supply pipe 310 .

Here, the blower 330 for supplying external air requires power for only the supply of external air (A) regardless of the power for transporting the processing gas (G2), so the suction blower 370 of the second embodiment to be described later. In comparison, a relatively low dose may be applied.

Next, a second specific embodiment of the outdoor air mixing means 300 is illustrated in FIGS. 3 to 6 .

As illustrated in the drawings, the outdoor air mixing means 300 according to the second embodiment of the present invention comprises an extended exhaust pipe 340 , an extrapolated ring body 350 , and a ring body adjustment unit 360 . can be

The extended exhaust pipe 340 is a pipe extending while communicating with the deodorization process tower 100, and may have an exhaust port 342 for discharging the mixed gas G3 at the extended end.

A plurality of vent holes 341 may be formed at regular intervals along the circumference at a predetermined position of the extended exhaust pipe 340 .

The extrapolated ring body 350 is formed in a ring shape having a predetermined width, and can be extrapolated to enable rotation in the extended exhaust pipe 340 at the position where the ventilation hole 341 is formed.

That is, the extended exhaust pipe 340 passes through the inner circumferential surface of the extrapolated ring body 350 , and the plurality of vent holes 341 formed in the extended exhaust pipe 340 may be covered by the extrapolated ring body 350 .

A plurality of external pores 351 are formed in the extrapolated ring body 350, and the plurality of external pores 351 correspond to the plurality of vent holes 341 formed in the extended exhaust pipe 340 and may be formed at the same arrangement interval. have.

The ring body adjustment unit 360 adjusts the relative position angle of the extrapolated ring body 350 with respect to the extended exhaust pipe 340 .

That is, the ring body adjustment unit 360 is an extrapolated ring body 350 installed on the outer circumferential surface of the vent hole 341 and the external air hole 351 with the extended exhaust pipe 340 as the center so that the positions of the vent 341 and the external pore 351 coincide with or deviate from each other. angle can be rotated.

When the position of the vent 341 and the external pore 351 is adjusted to match each other by the ring body adjustment unit 360, the vent 341 is opened as illustrated in FIG. 4 to extend the exhaust pipe 340 to the outside. It becomes possible to inhale air.

On the other hand, when the position between the vent 341 and the external pore 351 is adjusted to be shifted, the vent 341 is blocked by the extrapolated ring body 350 and closed, so that the intake of external air is changed to a blocked state.

The ring body adjustment unit 360 for adjusting the extrapolated ring body 350 so that external air is sucked or blocked in this way may be configured in various configurations that can provide rotational force to the extrapolated ring body 350 .

For example, as illustrated in FIGS. 4 to 5 , a pinion-shaped first gear 361 is formed in a certain section of the extrapolated ring body 350 , and the first gear is mounted on the cylinder rod of the driving cylinder 363 . By forming the second gear 362 in the form of a rack gear meshing with the 361, the linear movement force of the cylinder rod according to the driving of the driving cylinder 363 is converted into the rotational force of the extrapolated ring body 350, so that the extrapolated ring body ( 350) may be configured to rotate at a certain angle.

Of course, by forming a circular gear meshing with the first gear 361 on the rotation shaft of the drive motor while using the drive motor instead of the drive cylinder 363, the extrapolated ring body 350 may be configured to rotate at a certain angle. In addition, as long as it can provide rotational force to the extrapolated ring body 350, such as a chain-sprocket, a belt-pulley, it is natural that it can be applied without any particular limitation.

In this second embodiment, unlike the first embodiment, the external air A1 is not forcibly supplied, but is forcibly sucked through the extended exhaust pipe 340. For this purpose, a suction blower 370 and a damper for controlling the flow rate ( 380) may be further included.

The suction blower 370 may be provided in the extended exhaust pipe 340 at the rear end of the position where the extrapolated ring body 360 is installed, and provides suction power so that the outside air (A) is sucked into the extended exhaust pipe 340 inside. do.

At this time, when viewed in the gas flow direction, the suction blower 370 is located on the rear flow path of the odor gas G1 and the processing gas G2, so the suction blower 370 is the external air (A). In addition to the suction power, the odor gas (G1) flows into the deodorization process tower 100 and the processing gas (G2) is transported along the extended exhaust pipe 340, that is, the odor gas (G1) and the processing gas (G2). A blower having a relatively high capacity may be applied than the blower 330 for supplying outdoor air of the first embodiment described above so as to provide even power.

For example, suppose that the deodorization treatment possible air volume of the installed deodorization process tower 100 is 500 CMM, and the required air volume of the outside air (A) is calculated to be about 250 CMM.

Then, in the first embodiment, a blower 130 with a capacity of 500 CMM is separately provided as a configuration of the deodorization process tower 100 for the transfer of the odor gas (G1) and the processing gas (G2), while the outside air (A) The blower 330 for supplying outdoor air may be a blower having a capacity of about 250 CMM.

On the other hand, in the second embodiment, there is no need for the blower 130 to be separately provided as a component of the deodorization process tower 100, and the suction blower 370 is used to transport the odor gas G1 and the treatment gas G2. A blower with a capacity of about 750 CMM that adds up both air volumes can be applied to provide all the suction power of the outside air (A).

On the other hand, the air volume value of the outside air (A) described in the above example is literally just an example, and the required air volume of the outside air (A) is not set to a specific numerical value, and Specific calculation can be made by examining and analyzing the contained odor-causing substances.

That is, after examining the treated gas (G2) in a state in which the outside air (A) is not mixed, and analyzing which of the odor-causing substances contained in the treated gas (G2) is a substance with a high odor contribution rate, this contribution rate is high By applying the Webber-Fechner law, which shows the functional relationship between the odor intensity and the concentration of odor-causing substances, the air volume of the outside air (A) to be mixed can be calculated.

For example, assuming that a substance with a high odor contribution rate is hydrogen sulfide, Y = 0.95 logX + 4.14 [Y: odor intensity, X: substance concentration ( ppm)] to calculate the air volume of the outside air (A) to be mixed in order to lower the material concentration in the processing gas (G2) to the required concentration.

As above, since there is a large difference in the relative capacity of the blower 330 for supplying outdoor air of the first embodiment and the blower 370 for suction of the second embodiment, the blower 330 for supplying external air of the first embodiment is a relatively simple support. While it can be easily installed above a certain height from the ground using a structure, the suction blower 370 of the second embodiment is relatively difficult to install above a certain height from the ground through the support structure.

Accordingly, in the second embodiment, as illustrated in the drawing, the extended exhaust pipe 340 is disposed in a path extending from the stack 120 to the ground portion, so that the suction blower 370 may be installed on the ground portion.

Of course, the installation positions of the blower 330 for supplying outdoor air and the blower 370 for suction are not necessarily limited thereto, and the blower 330 for supplying outdoor air 330 may also be installed near the ground according to the installation environment or various needs, When the installation is relatively easy, such as when there is a ceiling structure near the stack 120, the suction blower 370 can be installed at a certain height from the ground without the need to extend the extended exhaust pipe 340 to the ground portion. can be fully understood.

The damper 380 may be provided in the extended exhaust pipe 340 in the section between the extrapolated ring body 350 and the suction blower 370 .

As illustrated in FIG. 6 , the damper 380 includes a damper housing 381 having an internal flow path, and is rotatably provided inside the damper housing 381 to allow gas passing through the internal flow path according to the rotation angle. It may include a blade 382 for adjusting the flow rate, and a damper motor 383 for rotating the blade 382 .

The damper 380 is interlocked with the driving of the ring body adjustment unit 360 to control the operation of the damper motor 383 so that the amount of air passing through the internal flow path can be adjusted according to whether the external air A is sucked.

That is, the damper 380 operates so that the internal flow path is completely opened by interlocking with the ring body adjustment unit 360 to be operated so that the external air is sucked in as illustrated in FIG. 6A , and the blade 382 is horizontally positioned. On the other hand, when the ring body adjustment unit 360 is driven to block the suction of the outside air (A) as illustrated in FIG. 6 (b), the blade 382 is rotated at a predetermined angle in conjunction with this to be inclined at an internal flow path. The operation is made so that the

In other words, when the damper 380 is sucked in the external air (A), the internal flow path is completely opened so as to correspond to the sum of the air volume of the transported processing gas (G2) and the air volume of the sucked outside air (A). , when the suction of the outside air (A) is blocked, the internal flow path is reduced and adjusted so that the air volume corresponds only to the air volume of the transferred processing gas (G2).

As described above, preferred embodiments of the deodorizing device according to the present invention have been reviewed, the deodorizing device of the present invention is provided with an external air mixing means 300 additionally configured in the exhaust passage of the deodorizing process tower 100, so that the discharge allowed as prescribed by the law It can be seen that it is possible to effectively prevent civil complaints and conflicts with the local community due to not only complying with the standards but also without causing discomfort to people due to the bad smell of living.

That is, the conventional deodorization device has a configuration in which the treated gas G2 is directly exhausted from the deodorizing process tower 100 after the odor gas G1 has undergone only the deodorization process, that is, the malodorous gas G1 → treated gas G2 → exhaust Contrary to the configuration of the process of the present invention, in the present invention, after the odor gas (G1) undergoes the same deodorization process, the treated gas (G2) is not immediately exhausted, but external air (A) and the outside air (A) through the outside air mixing means (300) There is a difference in the configuration in which the mixed gas (G3) is exhausted after being mixed and diluted, that is, the composition consisting of the process of odor gas (G1) → treatment gas (G2) → mixed gas (G3) → exhaust. In the present invention, the mixed gas (G3) in which the external air (A) is mixed with the processing gas (G2) is exhausted to dilute the odor-causing substances and to increase the exhaust diffusion power as the flow rate increases, thereby lowering the odor concentration compared to the conventional device. that can be effectively reduced.

In addition, in the deodorization apparatus of the present invention, since the structure of the deodorization process tower itself performing the deodorization process is hardly changed and an external air mixing means is added on the exhaust passage, not only the newly newly installed apparatus but also the already installed and operating It can be seen that it can be easily applied to the deodorization device without the burden of a large installation cost.

In addition, there is a convenience in that it is possible to more efficiently operate the deodorization device by selecting whether to mix external air according to the surrounding environment or conditions.

That is, in the case of the first embodiment, only by stopping the driving of the blower 330 for supplying external air, it is possible to operate the exhaust after only the deodorization process in the same manner as in the prior art without mixing of external air, and even in the case of the second embodiment When the ring body adjustment unit 360 is operated so that the vent hole 341 is closed (at this time, the damper 380 is interlocked to adjust the air volume.) Also, without mixing the external air, only the deodorization process is performed in the same manner as in the prior art, and then the exhaust is exhausted. Therefore, odor emission facility companies can conveniently exhaust the mixed gas mixed with outside air according to various needs such as the surrounding environment or operating conditions, and the operation that allows the treated gas to be exhausted without mixing the outside air. You can choose which one to use.

Above all, if the configuration of the conventional deodorization device is greatly changed in order to achieve the object of the present invention, for example, if the configuration is changed in a way to reinforce the deodorization process itself performed in the deodorization process tower, installation according to the configuration change And the overall efficiency of technology development is inevitably reduced by causing a problem in another aspect due to an increase in operating cost, and the deodorization device of the present invention deodorizes without changing the deodorization process performed in the deodorization process tower at all. Since it is a relatively simple configuration improvement that only adds a configuration that mixes only outside air to the treated gas after the process, it is possible to achieve a technical effect to solve the problem caused by living odor and minimize the increase in cost due to the configuration improvement. Therefore, it can be seen that the overall technology development efficiency is very high.

Preferred embodiments of the present invention have been described in detail above, but the technical scope of the present invention is not limited to the contents described in the above-described embodiments and drawings, and modified or It will be said that the changed equivalent configuration does not depart from the scope of the technical idea of the present invention.
