Description

A cabin air filter by composite of activated carbon fiber for car interior purification and its manufacturing method}

The present invention relates to an intake air purification filter and a method for manufacturing the same in a car by using an activated carbon fiber composite, and more particularly, by installing the intake air purification filter in the car air conditioner to fine dust and automobile smoke, exhaust gas flowing into the car The present invention relates to a filter for inlet air purification by using an activated carbon fiber composite that absorbs and removes harmful gases and odors that are harmful to a human body, thereby comforting a driver's and passenger's health and a vehicle's indoor environment.

With the increase in the number of automobiles, the road environment is getting worse and worse, so the driver and passengers who use the car demand a pleasant environment in the car.

In fact, the air flowing into the vehicle during road driving contains many malignant particulate matter such as pollen, asbestos particles, bacteria and road dust.

As a result, most of the vehicles have various harmful particulate matters and harmful gases that are generated on the road while driving, and the odor and bacterial dust generated when the heater or air conditioner is operated on a cold or wet day. As it flows into the interior, the driver and passenger are always exposed to an unpleasant environment.

Allergy caused by pollen in spring and bad smell of mold generated inside air conditioner in summer due to moisture Malignant particulate matter such as dust, diesel chute, and brake lining dust, which are fatal to health, are introduced into the car, threatening the health of drivers and passengers.

Preventing the inflow of harmful particulates and harmful gases caused by automobile exhaust gas from various roads, and only purifying air flows into the car, protecting the health of drivers and passengers and providing a pleasant indoor environment. There is a need for a variety of purification filters to keep the.

Automobiles, one of the important means of transportation in modern society, are the most convenient means of transportation used by the general public, and at the same time, they are the main culprit of environmental pollution which emits large amounts of air pollutants.

Recently, in order to suppress pollutants generated from automobiles, new vehicles have been put in a lot of efforts such as attaching a catalytic converter and using unleaded gasoline and lowering sulfur content of diesel.

However, efforts to reduce odors caused by fine dust, automobile exhaust, and soot generated from roads in urban areas and elsewhere are still poor.

Therefore, malignant particulate matter and unpleasant odors introduced into the vehicle during driving are deposited by penetrating into the bronchus and lungs, and there is a problem that the human body is continuously damaged such as asthma and dyspnea.

An object of the present invention for solving the above problems is to prevent the harmful particulates generated in the city and the roads of various areas during the driving of the vehicle and the bad smell harmful to the human body due to the exhaust gas and smoke fumes into the vehicle In addition to protecting drivers and passengers' health, they also have good collection efficiency, long life time, and fine dust for overseas exports. The present invention provides a filter for inlet air purification in a vehicle by using a long life activated carbon fiber composite, which is a cabin air filter satisfying simultaneous odor removal, and a method of manufacturing the same.

An object of the present invention as described above in the purifying filter for the adsorption and collection removal of odor due to fine dust and harmful gas contained in the air,

A primary filtration layer for imparting additional characteristics to constitute a short-fiber nonwoven layer of polyester base for antibacterial and to preferentially collect large particles in dust contained in the air; A second filtration layer of ultra-fine fibers composed of a fine particle control layer imparting electrostatic force to polypropylene microfibers and collecting and removing fine dust contained in air; Adsorption and support tertiary filtration layer consisting of a layer consisting of a layer of activated carbon fiber (polyester 55% + activated carbon fiber 45%) of polyester base to adsorb and remove harmful gases in the air It is achieved by providing a filter for inflow air purification in a vehicle by an activated carbon fiber composite, characterized in that it is combined and superimposed.

(1): blower motor (2): purification filter

(3): Evaporator core (4): Heater core

(5): air outlet (6): primary filtration layer for providing additional characteristics

(7): Secondary filtration layer of ultra-fine fibers (8): Third filtration layer for adsorption and support

When described in detail with reference to the accompanying drawings, the configuration and the operation of the embodiment of the present invention to achieve the object as described above and to perform the task for eliminating the conventional drawbacks.

1 shows a flow chart of an air conditioner installed in a vehicle and a mounting position of a filter for purifying intake air in an automobile by using activated carbon particles, wherein the air flowing in from the outside is controlled by a driver at a blower motor ( Aspirated by 1), the introduced air passes through the filter 2 for the inlet air purification by the composite of activated carbon fibers.

At this time, the malignant particulate matter and harmful gas contained in the air are collected and removed in the inlet air purification filter 2, and only clean air is introduced.

The introduced air is introduced into the vehicle interior through the air outlet 5 in accordance with the adjustment of the direction of the indoor inlet air of the driver via the heater core 4 via the evaporator core 3.

In this case, the performance of the filter depends on the material, structure and shape of the inlet air purification filter in the automobile by the composite of activated carbon fiber, the most important part of filtering fine dust and harmful gas in the air.

Figure 2 is a cross-sectional view of the detailed structure of the filter for intake air in-vehicle by the combination of activated carbon fiber.

The primary filter layer 6 for imparting additional characteristics as a pre filter is composed of a short fiber nonwoven fabric layer of polyester base for antibacterial and the like. Is the first to capture,

The second layer of ultrafine fibers, the second filtration layer (7), consists of a microparticle control layer that imparts electrostatic force to polypropylene microfibers, and collects and removes the fine dust contained in the air. do.

The third layer, which is the third layer for adsorption and support, is composed of a layer of activated carbon fibers (polyester 55% + activated carbon fibers 45%) of a polyester base, which combines two components. The bonding method is combined by thermal bonding, and serves to adsorb and remove harmful gas in the incoming air.

As a method of bonding the three-ply layer described above, it was prepared using a continuous method, which is an ultrasonic bonding method.

The continuous method, which is the ultra sonic bonding method, improves the shape and stability of the bent layer of the filter media so that the shape of the product does not change during the use period, and the life of the filter can be long. It is possible to make a filter for purifying intake air in cars by using activated carbon fiber composite.

As described above, according to the present invention, the collection efficiency of the fine dust and the adsorption removal efficiency against the odor due to the harmful gas are excellent with respect to the fine dust and the harmful gas contained in the air, and the form of the filter for the installation environment mounted on the vehicle. In addition, it is expected to have a significant effect on reducing the health and foreign currency of the people as a filter for inflowing air in automobiles by combining long-life activated carbon fibers with excellent stability and long exchange cycles.

The present invention is not limited to the above specific examples, of course, there can be various variations and modifications within the technical scope of the present invention.
