KR20150136185A - Air cleaner based on dried food waste adsorption agent - Google Patents

Abstract

The present invention relates to an air cleaner using a dried food waste adsorbent. Dust adsorption has been an issue due to frequent waste disposal which requires several filtration processes including a prefilter, a medium filter, an activated carbon filter, and a high-efficiency particulate arrestance (HEPA) filter. However, if applying food waste as the filter in the air cleaner, the dust adsorption becomes almost handleable at a reduced level of one-five hundredth of a filter change cycle of an existing air cleaner.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air cleaner based on dried food absorbent,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air purifier using a dry food adsorbent, and more particularly, to an air purifier that purifies air by using a dry negative complex dried from food waste as an adsorbent.

Air purifier (air purifier) is a device that purifies pollutants contained in the air and converts them into fresh air. Commercially available products are particularly beneficial to allergic and asthmatic patients, and tobacco smoke is removed to reduce the risk of secondhand smoke.

Air purifiers use a lot of power but bring a lot of environmental changes. For example, dirt, pollen, pet hair, mold spores, house dust mite, and tick excreta allergic to sensitive people. Tobacco smoke particles and volatile organic compounds can also be fatal to health. Air purifiers are used to reduce these air pollutants and are particularly useful for people suffering from allergies and asthma. In addition, air purifiers also reduce the need for periodic cleaning of the house.

Air purifiers are mainly used at home, and they are used in various places such as offices, hospitals and so on.

On the other hand, a large number of kitchen garbage disposal apparatuses have recently been developed as the cost of separate collection of food waste inevitably arises when an air purifier is used in a home in which the household is mainly used.

Air cleaners and food waste disposers have been recognized as completely separate devices, although clear air in the home and sustainable treatment of food waste are essential.

It helps to build a better living environment by replacing the filter of the air purifier with the dried food waste of the food waste disposal unit that has reached the appropriate technology level and solving the problem of the existing air purifier that needs to regularly replace or clean the filter Technology is necessary.

Different processes are used to purify the air, showing different effects. Each process removes various contaminants. There is an advantage to using one or more processes in a cleaner like this. Typical air cleaning methods are as follows.

Filter type: This method is the most mainstream method, in which air is sucked by a fan, such as an electric fan or an air conditioner, and then the filter is cleaned and the purified air is discharged again. Air purifiers adopting this method usually use a method of dust collection and filtration of particulates with a fine nonwoven filter called HEPA, and adsorption using activated carbon in the case of odor. There is also a model that uses an electric dust collection system, which is a technique using a plasma effect, which is an electric discharge effect. In addition, titanium dioxide photocatalyst is used in place of activated carbon, or ULPA, which is a finer filter than HEPA, is adopted.

Ion type: The ion type air purifier discharges ions in the air by flowing a high voltage through a fixed distance to the electrodes, and attaches them to the fine particles in the air. It is advantageous that power consumption is low and it is quiet. However, since there is no fan basically, it takes some time until it is purified, and the disadvantage is that the larger the room, the less effective it is.

Electric dust collection type: An air purifier adopting this method in which polluted air is purified by a dust collecting plate having a strong collecting power by using the electric discharge principle such as ion type is called a no filter purifier or anion purifier. Unlike the ionic type, the fan is used together. Although it has a small maintenance cost and can be used in a large amount of fine dust, the dust collecting efficiency is generally lower than that of a filter such as HEPA. The disadvantage is that periodic cleaning is necessary because the inside of the body is easily dirty.

Water filter type: It uses water like a filter to remove contaminants by using water's adsorption power. There is also a method in which water is added to the electric property to increase the collection power, or the water itself is showered. It does not cost extra because it uses water, but it is a disadvantage that there is no function of collecting odor and smell.

There are also hybrid products that combine the characteristics of a filter type and an electric dust collecting air cleaner.

The most widely used type of air purifier is a filter type, in which the air is sucked by a fan, then purified by a filter, and then the purified air is discharged again. The most uncomfortable thing consumers feel when using an air purifier is that the air purifier can not function unless it is regularly cleaned and replaced.

It is burdensome to the users who do not have professional knowledge to manage filters with different usage and lifetime according to each function such as HEPA filter made of fine nonwoven fabric, activated charcoal filter having deodorization function, basic filter of cotton or pulp material.

In order to improve the usability of air cleaners and to make them easier for consumers to use, it is important to reduce the filter pollution and increase the period during which the filter functions reliably.

In addition, even when using an ion-type or an electrostatic precipitating function, ionized gas molecules need to adhere to the dust and adhere to the surface, and a method for facilitating the cleaning of the adsorption unit should be devised.

In accordance with the above, there is provided a method of using the surface of a dried food waste inside a food waste disposer as an adsorbent of airborne dust.

According to another embodiment, there is provided a method of using a circulating fan of a food waste disposer and a multi-activated carbon filter as a part performing an air cleaning function.

According to another embodiment, the air introduced into the pulverizing / drying unit in the circulating fan is circulated through the food waste, the multi-activated carbon filter and the HEPA filter, and then discharged.

Therefore, when food waste is applied to the filter of the air purifier, the waste of the waste frequently discharged at a level that is only 1/500 of the filter replacement cycle of the existing air cleaner can be removed at various stages of the prefilter, medium filter, activated carbon filter and HEPA filter It can be able to cope with most of the adsorption of the dust which had to be handled.

In addition, since most of the dust is adsorbed on the surface of dried food waste having a specific surface area comparable to that of activated carbon, it is possible to prolong the cycle of replacing the expensive HEPA filter that filters deodorizing activated carbon filter and fine dust.

Further, if the replacement period of the filter is significantly increased, the maintenance cost of the air cleaner can be reduced, and the convenience of the consumer can be improved.

In addition, by adding the air cleaning function to the food waste disposer, it is possible to solve the problem by purchasing one product of two similar price appliances, thereby achieving excellent economy and marketability.

FIG. 1 is a view showing an air purifier portion according to the present invention added to an air introduction portion of a food processor, and FIG. 2 is a photograph showing food wastes dried at a moisture content of 6%.

The food waste treatment methods and treatment apparatuses disclosed in the existing patents (No. 1010176160000/1010530350000) have components essential to the air purifier.

Referring to FIGS. 1 and 2, a fan for circulating dry hot air and an activated carbon filter having multiple deodorizing functions are fully compatible with existing air purifiers. Thus, a deodorizing filter having a multi-activated carbon structure can be confirmed through the illustration of FIG.

Meanwhile, the circulated fan passes the pulverized / dried food waste before the air enters the multi-activated carbon filter. The dried food waste has a specific surface area as large as that of activated carbon. The use of such a specific surface area can be used not only as an adsorbent capable of adsorbing various harmful dusts in the air but also at the end of treatment of food wastes, there is no need to separately filter the filter. Thus, it can be confirmed from a food waste photograph made in a state having a moisture content of 6% after being dried / pulverized in FIG.

In addition, when the air cleaning function is operated before the water content of the filter 1010176160000 is lowered, the same function as the filter of the water filter type air cleaner can be performed, and the deodorizing function member, which is a disadvantage of the existing water filter type air cleaner, It can be solved by a multi-activated carbon filter built in a waste disposal apparatus.
