DE202018004314U1 - Hybrid air purification system - Google Patents

Abstract

Compact air box characterized in that a compact air box (insulated housing) can be equipped as needed with filters, generator and motor. The existing inspection flaps are for easy maintenance. The system only works in a closed state.

Description

A hybrid exhaust air purification system works differently than conventional filter systems such as plasma systems or activated carbon filter system. The exhaust air purification system is connected after the extractor hood. The exhaust air motor is located separately in an air box, in the filter box or in the extractor hood, depending on requirements and location. A specially calculated combination of grease filter, ozone / plasma, activated carbon filter and UV-C creates an efficient vapor and odor filter.

By cooking, roasting, grilling and other production in the kitchen arise partly intense odors that also accumulate in the rooms and in the extractor and pipes. This negatively affects the breathing air and the indoor climate. The emission also leads in the environment of the production site (kitchen / restaurant) to high odor nuisance up to the pollution in the air.
Furthermore, the production facility, the guest room and the extractor system create a fertile breeding ground for bacteria, fungi and fours. These in turn negatively impact human and material negatively.
The hybrid exhaust air purification system cleans and filters the exhaust air several times, sterilizes bacteria, viruses and fungi and neutralises bad smells.

The specified in the protection claim invention is based on the problem to construct a device that permanently, in private and commercial use, the exhaust air so cleans, filters and sterilizes that almost neutral air is returned to the room or discharged to the outside.

These problems are solved with the features listed in the protection claim.

The invention is explained as follows:

Pre-filter:

The aspirated air is prefiltered here in several stages. In the example lamellar filter, metal-machine filter and microfiber filter also optional paper bag filter or HEPA filter. In order to simplify maintenance and cleaning, access is to be provided by means of an inspection flap.

Bulk:

The main part contains an ozone generator / ion generator. Here in the plasma O3 is produced as well as in the splitting of the molecules, electrons and ions. The exhaust air is additionally irradiated with UV-C. Through these processes, the cell membranes of bacteria, spore formation in fungi and viruses are destroyed by the docking mechanism. Furthermore, odors are neutralized and from the previously obtained ozone (O3) again oxygen (O2).

afterfilter:

This section contains the charcoal filter that can be fitted depending on the volume of air required. Here, the last odors are almost completely eliminated and other ozone molecules split.

Exhaust Engine:

Depending on the size of the hybrid exhaust air purification system, the exhaust air motor is located at the end of the filtration or in the case of smaller systems in the extractor hood and thus before filtration.

Claims (5)

Compact air box characterized in that a compact air box (insulated housing) can be equipped as needed with filters, generator and motor. The existing inspection flaps are for easy maintenance. The system only works in a closed state. Ozone generator / ion generator, characterized in that generated in the ozone generator / ion generator plasma with ozone and in the splitting of the molecules, electrons and ions. UV-C sterilizer, characterized in that the air is irradiated in the air stream and thus additionally sterilized. Activated carbon filter, characterized in that the air is cleaned and sterilized by the above filtration. In the activated carbon filter, the ozone and ions have a longer effect and remove odors and fats more efficient. Molecules are captured by the filter surface and oxidized. During the process, the remaining ozone is almost completely decomposed into oxygen. Through this type of regeneration, the life of the activated carbon filter is extended many times. Combination characterized in that the combination of all the requirements of the efficient exhaust air purification system is created and as needed, as shown in the drawing, can be built in different sizes. The exhaust air can, if desired, be returned to the room in a purified state via the discharge connection or be discharged to the outside.
