Description

How to deal with odor and fine dust in restaurants

The present invention relates to a method and apparatus for treating odor and fine dust, and more particularly, to a method for effectively treating odor and fine dust generated in a restaurant.

In restaurants, odors and fine dust are generated. In particular, a large amount of odor and fine dust is generated during the cooking process of food and the processing of food waste. Meat restaurants generate remains, fine dust, and odor components during the process of roasting meat, and the amount of fine dust generated by meat restaurants accounts for about 1.5% of the amount of fine dust generated. In the case of Jeju Island, the installation of reduction devices is being made mandatory.

It is difficult to treat the substances generated in these restaurants with conventional filters and photocatalytic methods. This is because the filter method cannot completely filter out the chemical components of bad odors, and the oil remains in the oil component, which seriously lowers the filtration performance of the filter and clogs it.

The method by the electrostatic precipitator also consumes a lot of energy and causes a decrease in efficiency due to oil deposits, and fine chemicals and odor components are not well removed. In the case of the photocatalytic method, it is impossible to completely decompose difficult-to-decompose particulate matter and oil droplets, and the photocatalytic reaction on the surface is inhibited by the oil droplets.

In particular, the exhaust gas of restaurants contains a large amount of substances vaporized through phase change by heating during the cooking process, so it is difficult to treat only with the existing treatment method, and a separate condensation process is required. In other words, in the past, individual technologies such as water removal by condensing device, odor removal by odor treatment device, inorganic fine dust removal by electric dust collector and filter, oil removal by oil residue removal device, and microchemical removal by photocatalyst and filter, etc. exists only as

Regarding the odor reduction device for restaurants, Korean Patent Registration No. 1699891 relates to an exhaust gas treatment device for a grilled restaurant, and proposes a device for removing oil/water mixed fine particles by passing the exhaust gas through a cartridge filled with waste paper napkins In order to treat gas containing oil, Korea Patent Registration No. 1379360 proposes a odor removal device in which the gas is burned through a dust collector after oil separation.

On the other hand, existing air purifiers installed indoors purify the inside air while blocking the outside air, but it does not ventilate with the outside air, increasing the risk of spreading infectious diseases such as corona, and purifying the constant indoor air without supplying fresh air. Since it increases the carbon dioxide concentration, there is a limit to the creation of a comfortable indoor environment.

Accordingly, there is a need for an air purification method capable of integrally removing moisture and odors, inorganic fine dust, organic substances, and relics generated in restaurants, and further killing infectious pathogens.

The method for reducing fine dust and odor according to the present invention relates to a ventilable air cleaning method capable of effectively treating moisture and odors, inorganic fine dust, organic fine dust, and oil remains in food waste treatment and cooking processes. According to the present invention, it is possible to have a sterilization effect of killing infectious pathogens by performing secondary treatment with a photocatalytic device after the first treatment using restaurant washing water and surfactant.

The method for treating fine dust and odor according to the present invention comprises: transferring the washing water separated from solid-liquid after being used as domestic water to a washing tower as air washing water; introducing air containing odor and fine dust into the washing tower; washing the air introduced into the washing tower in contact with the washing water; and discharging the purified air formed by the washing and the washing water used for washing, respectively, from the washing tower.

The present invention particularly relates to a method of treating fine dust and bad odors generated in restaurants, and may be food smoke generated during food cooking or bad odors generated from food waste. Hereinafter, each step will be described in detail.

First, the washing water separated from solid-liquid after being used as domestic water at least once is transferred to the washing tower as air washing water.

In the present invention, the washing water for cleaning the air containing bad odors or fine dust is characterized in that the washing water used for living water. The washing water used at least once is washing water that has already been used at least once in a restaurant, etc., which is used for washing dishes, food washing, etc.

The washing water has been used more than once and already contains a surfactant. As an embodiment, if washing water used for washing dishes, it may contain a surfactant for washing dishes. This washing water is generally used once and immediately flows into sewage. The present invention relates to a method of reusing such washing water for air cleaning.

Since the gas generated in restaurants contains oil, it is difficult to apply a general air purifier, but the washing water of the present invention contains surfactant, so it is easy to dissolve the oil, the residence time is short, and the degree of contamination is low because it does not decay. It can be used for air cleaning.

The washing water already contains a surfactant, but if necessary, a surfactant may be additionally added to the washing water before the washing water flows into the washing tower, and the washing ability may be increased through a foam generating device. Additional input of the surfactant or foaming treatment may be performed in front of the storage tank or between the storage tank and the washing tower.

In addition, since the washing water used at least once as household water contains solids such as food waste and other contaminants, only washing water from which solids are removed through solid-liquid separation can be sent to the washing tower. The solid-liquid separation may be performed by a filter or other known methods may be used, and in the case of a sink or a sink, solids can be easily removed through a sieve installed in the sewage inlet. In the present specification, the liquid washing water from which the solids are removed is referred to as washing water and serves to clean the polluted gas or air in the washing tower.

After solid-liquid separation, the washing water transferred to the washing tower and used for air washing is water for daily life, and the water temperature may be 15 to 30 ℃, 18 to 28 ℃, or 20 to 25 ℃. That is, the washing water used in the present invention is close to room temperature, so it is easy to condense high-temperature water vapor and oil droplets, and energy can be reduced by controlling the temperature of the exhaust gas to and from room temperature regardless of the season. Accordingly, if the air introduced into the washing tower is high temperature such as outdoor air or food smoke in summer, it is cooled to an appropriate temperature close to room temperature by the washing water, so that unpleasant air may not be emitted when discharged outdoors. Even when the purified air is discharged into the room by introducing it into the washing tower, the temperature of the cold air can be raised by the washing water at room temperature, thereby preventing the reduction of the indoor temperature, thereby saving heating and cooling costs and energy. .

The washing water may be stored in a washing water storage tank before being transferred to the washing tower. The washing water storage tank may be a storage tank consisting of two stages or two or more stages. In this case, the first-stage storage tank may be a circulation storage tank, communicates with the washing tower to circulate, circulates the washing water in the first-stage storage tank, and can be repeatedly used as the washing water in the washing tower. That is, the washing water discharged from the washing tower can be circulated and reused again for washing contaminated air. It can be reused after additional input of surfactant or filtering of contaminants in the circulation process.

Repeatedly used washing water can be discharged to sewage when its ability to remove pollutants such as fine dust and odor substances is reduced or saturated, and at this time, the washing water from the second storage tank can be moved to the first storage tank to resume circulation. Therefore, each of the storage tanks constituting the washing water storage tank may be connected to each other.

Next, air containing odor and fine dust is introduced into the washing tower.

The air containing the odor and fine dust may be gas generated from food smoke or food waste in an indoor restaurant such as a restaurant. Smoke generated while cooking food or gas generated from food waste disposal contains a large amount of substances that cause odor and fine dust. In addition, the air containing the odor and fine dust may be outdoor (outside) air. Therefore, the method for treating odors and fine dust according to the present invention can be applied to both introducing indoor air and discharging it to the outdoors or introducing outdoor air and supplying it indoors.

In the case of introducing outdoor air, in particular, outdoor air containing a large amount of fine dust can be introduced into the washing tower and then purified and supplied to the room. Since the inflow of air is possible, ventilation is possible, oxygen supply is possible, and carbon dioxide concentration is not increased. In addition, ventilation is essential for pathogens that can be transmitted through air, such as COVID-19. In winter, on days with a lot of fine dust, or when the outside air quality is poor, ventilation is not good and only an indoor air purifier is operated. It is common to do However, according to the present invention, since outdoor air is purified and introduced as described above, it can be operated regardless of outdoor air quality and can prevent the indoor accumulation of infectious viruses, so that the function of preventing infectious diseases can be expected compared to indoor air purifiers. In the case of introducing indoor air, it is also possible to purify the air with ventilation as it purifies the bad air in the room and sends it out to the outside. Therefore, the present invention can be said to be an open air purification method that connects indoors and outdoors.

It is preferable that the air introduced into the scrubbing tower flows into the lower part of the scrubbing tower and diffuses to the upper part of the scrubbing tower.

Next, it is a step in which the air introduced into the washing tower is washed in contact with the washing water.

In the scrubbing tower, the washing water is brought into direct contact with the contaminated air introduced from the lower part of the scrubbing tower, so that washing can be performed. Moisture in polluted air such as food smoke, water-soluble substances, inorganic substances such as fine dust, or mixtures thereof can be effectively removed by the washing action of the washing water containing the surfactant in the washing tower.

As an embodiment of the present invention, in the washing tower, the washing water flows into the upper part of the washing tower and flows in the lower direction of the washing tower. may have been As another embodiment, the washing tower may be a tank-type washing tank filled with washing water, and air introduced into the washing tower may be introduced into the lower portion to contact the washing water in the form of bubbles.

Next, the purified air formed by the washing and the washing water used for the washing are discharged from the washing tower, respectively.

The washing water used for the washing may be discharged to the lower part of the washing tower and discharged to sewage or may be transferred to a circulation storage tank and circulated, and the purified air may be discharged to the upper part of the washing tower.

The purified air discharged from the scrubbing tower can be cooled or heated by the washing water and maintained at a temperature close to room temperature of 15 to 30 ° C, 18 to 28 ° C, or 20 to 25 ° C, so that comfortable air can be discharged outdoors or indoors. can

In addition, the method for treating fine dust and odors according to the present invention may further include a photocatalytic treatment of the purified air discharged from the washing tower. In this case, water-based, oil-based, and inorganic substances are removed through a two-stage purification process that removes inorganic substances, light particulate substances, water-soluble chemicals, oil residues, etc. from the washing tower, and then completely oxidizes organic substances and non-aqueous chemical substances through photocatalytic treatment. Since the removal of air can be performed integrally, the quality of the purified air can be further improved.

The photocatalytic treatment step may be a step of passing the purified air through a photocatalyst treatment device filled with a transparent filter material coated with a photocatalyst. The photocatalytic treatment can decompose chemicals in odors and fine dust and kill pathogens. At this time, for the light transmittance of the photocatalyst filter material, the photocatalyst may be coated on a transparent filter material such as glass beads, and the shape of the transparent filter material is not particularly limited, but a cylindrical transparent filter material may be used to maximize the contact surface.

On the other hand, the apparatus for treating fine dust and odor according to the present invention is a washing tower for cleaning air containing odor and fine dust, wherein the washing water inlet formed in the upper part of the washing tower and the odor and fine dust formed in the lower part of the washing tower An air inlet comprising a, a washing unit in which the introduced air is washed in contact with the washing water, a purified air discharge unit formed on the upper part of the washing tower to discharge the purified air formed by the washing, and a lower part of the washing tower formed in the washing tower a washing tower including a washing water discharge unit for discharging washing water used for washing; and a sewage connection part connecting the washing tower and the sewage pipe.

The sewage pipe is connected to a sewer provided in a sink, a sink, or the like. The sewer is not particularly limited as long as it is a sewer that flows the sewage after using the water. In one embodiment, the sewer may be a sink drain. In this case, the washing water flowing into the sink can be drawn and used as the washing water of the present invention.

The sewer may include a solid-liquid separator for separating and discharging liquid washing water by solid-liquid separation of the washing water used for domestic water, and the solids are removed by the solid-liquid separator and only the liquid washing water flows into the sewage, and the sewage connection part is a sewage. It is to transfer the flowing liquid washing water to the washing tower.

The air inlet including the odor and fine dust formed under the washing tower may be connected to a hood installed indoors. Therefore, indoor air can be sucked in through the hood, transported to the washing tower, cleaned, and then discharged to the outdoors, so it is possible to purify the air that can be ventilated. In addition, the air inlet may be connected to the outdoors so as to introduce outdoor air. In this case, it is possible to clean the air that can be ventilated because outdoor air can be sucked in, transported to the washing tower, cleaned, and then discharged into the room.

The washing unit in which the introduced air is washed in contact with the washing water may be divided into multi-stage divisions. The purification air discharge unit formed on the top of the cleaning tower and discharging the purified air formed by the cleaning may be directly connected to the outside or connected to the photocatalytic processing device.

A washing water discharge unit formed under the washing tower to discharge the washing water used for washing may be connected to a circulation storage tank and a sewer in the washing water storage tank. If the cleaning ability of the washing water is sufficient, it is transferred to the circulation storage tank and circulated.

The front end of the washing tower or the washing water storage tank may include, connect, or include a surfactant storage tank or a surfactant input unit for additionally adding a surfactant to the washing water. In addition, it may include a bubble generating device for generating bubbles of the washing water in front of the washing tower. The foam generating device may be a stirrer, a mixer, or the like.

The front end of the washing tower may include a washing water storage tank for storing or circulating the washing water. The washing water storage tank is a single storage tank or is composed of two or more storage tanks, and when there are two or more stages, at least one of the storage tanks communicates with the washing tower to circulate the washing water. As the washing water discharged from the washing tower is circulated, a surfactant can be added, so that the washing power can be used to the maximum.

In the case of having two or more stages of storage tank, it may be composed of a circulation storage tank for circulating washing water and a preliminary storage tank for storing preliminary washing water, or may consist only of a preliminary storage tank. Connected to the solid-liquid separator may be a preliminary storage tank. The two or more stages of the storage tank may be connected to each other, and when the washing water in the circulation tank is saturated and discharged, the washing water stored in the storage tank may be moved to the circulation tank to continue circulation and washing.

The purified air discharge unit may pass to the outside. In addition, it may further include a photocatalyst treatment device for purifying the photocatalyst before discharging the air discharged from the washing tower to the outside. The photocatalyst processing device may be a column filled with a photocatalyst-coated transparent filter medium. The transparent media may be glass beads. The shape of the transparent filter medium is not particularly limited, but is preferably cylindrical.

The method and apparatus for treating fine dust and odors of the present invention can be applied to various indoor places, and in particular, since they are useful for removing odors and fine dust generated during a food waste treatment process and a cooking process, they can be effectively used in restaurants. In addition, it relates to an air purification method using outside air rather than circulating the air indoors, and it is possible to provide an air cleaning method capable of ventilation. Furthermore, it is possible to prevent the transmission of infectious diseases through the ventilation function and the pathogen killing function, thereby promoting public safety, and thus it is expected to be widely used in related industries.

Although preferred embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments described above, and those skilled in the art can implement various modifications without departing from the gist of the present invention.
