Description

Modular air purifier {MODULAR AIR PURIFIER}

The present invention relates to a modular air purification device, and more particularly, to introduce odors introduced into the storage unit into the purification unit, and at the same time as the UV emission from the UV emission unit, contact with a photocatalyst (TiO2) coated around the inside of the purification unit. It relates to a modular air purification device for purifying the odor introduced by the photochemical reaction.

In general, the odor that makes people feel unpleasant is that it stimulates the nervous system of a person and causes mental and physical damage.According to the Air Environment Conservation Act, hydrogen sulfide, mercaptans, amines, and other irritating gaseous substances are used for the human sense of smell. It is stipulated that it refers to a smell that stimulates and gives discomfort and disgust. In particular, in Korea, ammonia, methyl mercaptan, hydrogen sulfide, methyl sulfide, methyl disulfide, trimethylamine, acetaldehyde, styrene, etc. are designated as odor substances.

These odor-causing substances are very diverse depending on the source, and refineries, chemical plants, wastewater and livestock wastewater treatment plants, sewage treatment plants, and municipal waste landfills are considered as major sources of odor in cities.

In particular, in basic environmental facilities such as sewage treatment plants and livestock waste treatment plants, the above-described odor is generated and is considered a hateful facility because it is the subject of major civil complaints, but it is a major problem as an essential facility that is indispensable to people's life or the lives of the local residents. The occurrence of odor that emerges as a result must be resolved.

On the other hand, conventional odor treatment methods are largely classified into physical, chemical and biological treatment methods, and currently mainly used methods include combustion method, washing absorption method, oxidation method, adsorption method, microbial treatment method, and the like.

However, the combustion method is expensive to maintain and there is a risk of explosion. In addition, the application range of the washing and absorption method is narrow, and it may be difficult to treat complex odors. In addition, the oxidation method may have insufficient performance, and the adsorption method may have a problem that the adsorption material needs to be replaced and a pretreatment step must be performed in parallel.

Accordingly, in recent years, there is a situation in which technology transition is being made to a biological method that is more economical and more efficient than physical and chemical deodorization methods, mainly in the United States, Japan, and Europe.

However, purification devices using biological treatment methods developed so far require a lot of time and effort to exchange decomposition substances that are loaded inside and decompose odors after some time has passed. It is required, and there is a disadvantage that it is difficult to repair and manage.

In addition, it is desirable to remove the air purifier by grasping the type of odor to be purified and the characteristics of the generated dust, but since it is manufactured to treat general odors and dusts that have been popularized, it is necessary to remove specific odors and dusts. In order to remove specific odors and dust after designing and installing the air purifier, it is necessary to redesign and reinstall the existing air purifier after dismantling, resulting in a problem of wasting a lot of cost and time.

The storage unit 100 is provided with an inlet 110 through which odor is introduced, and a communication port 10 at one side thereof.

The storage unit 100 may be manufactured in a form capable of accommodating odor sources generated in homes, offices, workplaces, etc. as a space is formed therein, and odors may be sucked through an inlet using a blower or the like.

A purification unit 200 is installed on one side of the storage unit 100. The purification unit 200 has an opening 20 formed on one side thereof, and is inserted into the communication port 10 of the purification unit to communicate with each other.

At this time, by installing a sealing material such as an O-ring for sealing on either the outer peripheral surface of the communication port 10 or the outer peripheral surface of the opening 20, it is possible to prevent odor from leaking out between the joints in advance, and the communication port 10 And the opening 20 is preferably installed to be sealed.

Since the sealing installation method is already an open technical idea, the following description will be omitted.

In addition, the communication port 10 is manufactured in the form of a corrugated pipe, so that when each unit cannot be loaded or the installation location is narrow, the communication port 10 may be extended and extended to the opening 20 to be installed.

Accordingly, the communication port 10 and the opening 20 may be installed on all four sides of each unit, and may be arbitrarily changed and installed by the operator in consideration of the installation location of each module.

At this time, a bio curtain (not shown) is installed to surround the communication port 10 and the opening 20.

The bio-curtain (not shown) is a type of light-shielding film, and is manufactured by using high-density polyethylene (HDPE) to act as a filter when air is moved, so that some odors can be removed.

In addition, a spacer (not shown) is installed under the outer circumferential surface of the communication port 10 so that when each unit is stacked and installed, a space is separated by the thickness of the spacer (not shown) to attenuate the vibration generated in each unit and transmit it to other units. It can act as a buffer to prevent it.

In addition, it is a means for discharging water that is sprayed from the nozzle 430 by installing a discharge pipe 450 on the other side of the water tank 410 to collect pollutants. The discharge pipe 450 may be transferred to a water treatment facility or discharged to a sewer, but it is preferable to separately install a water filter in the discharge pipe 450 to discharge purified water to prevent environmental pollution.

A discharge unit 500 is installed on one side of the cleaning unit 400.

It is installed to communicate with each other through a communication port 10 formed on one side of the cleaning unit 400 and an opening 20 formed on one side of the discharge unit 500, and an air outlet 510 is formed on the other side to be purified. It is to exhaust air to the outside.

In another embodiment of the present invention, the storage unit 100, the purification unit 200, the cleaning unit 400, and the discharge unit 500 are each manufactured in the form of an independent block module to expand or contract by adding each module. Can be installed.

For example, one storage unit 100 module, two purification units 200 modules, three cleaning units 400 modules, and two discharge units 500 modules may be installed in combination. It is possible to economically remove odors and dusts by identifying the processing capacity and components of odors and dusts, omitting and removing unnecessary modules from each unit in the form of a block module, and adding only necessary modules.

Each of the units can be continuously installed in a longitudinal direction or a transverse direction, and it will be noted that it can be changed by a person skilled in the art.

One side of the storage unit 100, the purification unit 200, the cleaning unit 400, and the discharge unit 500 is provided with a coupling groove 31 and a coupling protrusion 32 on the other side. The coupling groove 31 and the coupling protrusion 32 are interleaved when each unit is coupled.

At this time, a sealing portion 33 is installed on the inner circumferential surface of the coupling groove 31 and the outer circumferential surface of the coupling protrusion 32 so that the coupling groove 31 and the coupling protrusion 32 are coupled to each other in close contact and compression to maintain airtightness. I can. The upper surface of the sealing part 33 has a grid-shaped groove or a honeycomb-shaped groove, so that the coupling groove 31 and the coupling protrusion 32 are in close contact with each other in a grid-shaped groove or a honeycomb-shaped groove. It can be deformed into a vacuum state and maintain airtightness.

In addition, as shown in Fig. 6(b), the storage unit 100, the purification unit 200, the cleaning unit 400, and the discharge unit 500 are coupled by a mutual fixing means 30, It is sealed and coupled, and the fixing means 30 can be fixed to each other using a clamp or a hook.

A dust sensor and an odor sensor are installed inside the storage unit 100, the purification unit 200, the cleaning unit 400, and the discharge unit 500.

The dust sensor and the odor sensor may apply a machine learning algorithm to determine error data (the concentration of the odor, the degree of the odor, the degree of the dust, etc.) and increase the recognition rate of the error situation to increase the odor purification rate.

At this time, a control module (not shown) for controlling the operation of the operation unit 300, the UV emission unit 210 and the operation fan 310 is further installed.

The control module (not shown) provides a function of operating or stopping the operation unit 300 and the UV emission unit 210, etc., but additionally receives data from the dust sensor and the odor sensor, and the operation unit ( It plays a role of controlling the intensity and turning on and off the operating fan 310 of the 300), and performs a function of processing data by applying a machine learning algorithm to be described below.

More specifically, the machine learning algorithm learns data input from a dust or odor sensor by applying a specific machine learning algorithm, thereby separating error data that is momentarily incorrectly measured due to disturbances in the surrounding area.

Accordingly, it is possible to process data in a robust form such as instantaneous external noise, and as a result, the strength of the operating fan of the operating unit can be adaptively controlled according to the situation through the control module (not shown).

In an embodiment, the machine learning algorithm may employ a binary classification method that learns and determines whether data input from the sensors is normal or abnormal. In addition, in the case of the above-described binary classification, since a lot of time is required for initial learning, there may be a disadvantage in that the accuracy of the trained model is not high in the initial stage, and by additionally combining and using the Adaboost algorithm related to this initial learning, the sensor Instantaneous errors in the data received from them can be properly handled.

In addition, by controlling the operation status of each unit (for example, 100, 70, 50, 30% operation, etc.) by synthesizing external weather information and the dust sensor and odor sensor information through external communication, power waste can be prevented or more efficient. By operating each unit, the efficiency of removing odors and dust can be improved.

[Experimental Example 1] Odor removal test according to the type of photocatalyst

In order to perform the odor removal test according to the type of photocatalyst, five purification units equipped with a UV emitting unit were prepared, and five types of photocatalyst materials (TiO2, ZnO, KTaO3, SnO2, CdTe) were coated on the inner periphery of the purification unit, respectively, and odor At the same time as the influx of UV rays, the degree to which odors were removed as photochemical reactions with different photocatalytic materials occurred were tested, and the experiment was conducted after photochemical reactions took place for about 10 minutes.

The test sample that generates odor was used as a test sample by decaying about 1 kg of food waste commonly discharged from home for 120 hours at room temperature at 25°C. For accurate measurement of odor, an odor intensity meter purchased from COSMOS (Model: XP -329IIIR) was used to measure the odor.

Degree of odor Classification of odor intensity Explanation 0 Odorless Relatively odorless, so that the normal person cannot sense anything with his sense of smell One Detection odor You don't know what the smell is, but you can feel the smell. 2 Normal odor The state of knowing what it smells like 3 Strong odor It refers to a strong smell that can be easily detected, for example
The state of smelling cresols in a hospital 4 Extreme intoxication Very strong smell, for example in the summer
Severe smell 5 An unbearable odor An intense odor that is difficult to bear, and a state in which breathing seems to be stopped.

In addition, in order to evaluate the degree of odor transmitted to the user's sense of smell, eight measurers evaluated the odor discharged through the air outlet based on Table 1 (the odor intensity sensory method standard).

TiO2 ZnO KTaO3 SnO2 CdTe Odor level 0.14 0.65 0.41 0.38 0.92 Olfactory evaluation 0 2 One One 3

As shown in Table 2, in the case of TiO2 coating, the odor removal rate was higher than that of other photocatalyst materials with the olfactory evaluation and odor level, whereas the odor removal rate was lower than that of other photocatalyst materials in the case of CdTe coating. I can confirm.

Therefore, the TiO2 photocatalyst according to the present invention has the advantage of stably removing odor and being able to remove it in a short time with high efficiency.

[Experimental Example 2] Odor removal test according to UV wavelength

For the odor removal test according to the UV wavelength, 7 TiO2 photocatalyst coated purification units were prepared, and a UV emission part was installed in the purification unit, but the UV wavelength was 350 nm, 355 nm, 360 nm, 365 nm, 370 nm, It was set to 375 nm and 380 nm, respectively, and after photochemical reaction took place for about 10 minutes, the experiment was performed.

The test sample generating odor was used as a test sample by decaying about 1 kg of food waste commonly discharged from home as in Experimental Example 1 for 120 hours at room temperature at 25°C. For accurate measurement of odor, XP-329IIIR purchased from COSMOS The odor level was measured using an odor intensity meter.

In addition, in order to evaluate the degree of odor transmitted to the user's sense of smell, eight measurers evaluated the odor discharged through the air outlet based on Table 1 (odor intensity sensory method).

350 nm 355 nm 360 nm 365 nm 370 nm 375 nm 380 nm Odor level 0.14 0.11 0.1 0.08 0.09 0.12 0.11 Olfactory evaluation 0 One 0 0 0 One One

As shown in Table 3, the odor removal rate for the UV wavelength at 365 nm was higher than that of other UV wavelengths for the olfactory evaluation and odor level, while the odor removal rate for the UV wavelength at 355 nm compared to other UV wavelengths You can see that this is low.

Therefore, the UV wavelength according to the present invention has been found to be stably removed at 365 nm through experiments, and has the advantage of being able to remove in a short time with high efficiency.

Since the embodiments described in this specification and the configurations shown in the drawings are only the most preferred embodiment of the present invention and do not represent all the technical spirit of the present invention, various equivalents that can replace them at the time of application And it should be understood that there may be variations.
