Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a regenerative air purifying device that is equipped with a radiation means such as a mercury lamp and in which air flows through an electric field within an electron cloud forming member. .

[Conventional technology]

It is known to sterilize air by passing it through an electrostatic field. However, ozone is produced as a result (German Patent Specification Box 2.71
52.824 and 2,205,885).

Furthermore, o3 (ozone) can be reduced to 02 (M element) by oxidizing metal substances (see British Patent Specification Box 1.400.519).However,
This filter method is not particularly effective. Moreover, the filter material sometimes has to be obtained.

[Problem that the invention seeks to solve]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an air cleaning device that can more effectively sterilize air and neutralize ozone.

[Means for solving problems]

The air purifying device according to the invention is characterized by a radiation means surrounded by a charge-absorbing casing. As a result, the ozone molecules are positively charged, thereby promoting the reaction and neutralization by the negatively charged ozone molecules.

〔Example〕

The air purifying device according to the present invention operates according to the regeneration principle, and the configuration of one embodiment thereof is shown in FIG.

As shown, a radiation means 1, such as a mercury lamp, is provided. By applying 220VAC (AC220V>), the wavelength of the emitted radiation is 300~400nu
) range tonal. If a voltage of 8000V is applied, the wavelength range changes to about 165nn+. At a wavelength of 21 Onlli, the destruction of DNA (deoxyribonucleic acid) molecules and thereby of bacteria and viruses occurs. At a wavelength of 250 nllll, cell division occurs and the cell division is so fast that the cells produced are not viable.

The radiation bombardment liberates oxygen, hydrogen and nitrogen bound to heavy molecules such as sulfur, chlorine or metals. The heavy threats are detected and accepted by the materials that make up the chamber, while the liberated oxygen molecules produce ozone. However, due to the fact that the heavy particles detected and captured by the chamber material are negatively charged, the ozone molecules are positively charged (the chamber material is preferably a semiconductor or a nonconductor). . An electric field generating element, preferably a capacitor-like element 4, is placed in the shadow of the radiating element, which generates negatively charged 03 molecules.

When a positively charged 03 molecule encounters a negatively charged 03 molecule, the oppositely charged molecules recombine and become 0.
Generates 2 molecules.

The voltage drop on the capacitor-like member 4 is, for example, 5ooov.
, and the voltage drop is such that the radiating means is 16
This corresponds substantially to the voltage required to emit electromagnetic radiation tJJ lines with a wavelength of 50111.

Voltage multiplier rectifier circuit
r) M is a sufficient number of capacitors C interconnected via rectifier diodes D such that the charge is conducted in one direction only, as the detailed configuration is shown in FIG.
It consists of Figure 2 shows only 1o capacitor C
This shows the case where the

The capacitor-like member 4 is constituted by a blade door with metal coatings 7a and 7b on both sides. The number of plates 7 can vary. The surface area of each plate 7 is 10×IQcs2. The intermediate spacing of the plates measures 1 cm in this case. A casing 2 surrounding the radiation means 1 and the capacitor-like member 4 comprises:
For example, it is made of flexible lead-containing plastic. Also,
A separate lead-containing coating may be applied to the outside of the casing 2. A blower 3 is arranged in an inlet opening 9, which inlet opening is configured such that no radiation from the radiation means 1 can escape.

An air purifier with a power consumption of 80W can reach 60m/hour.
It can process 3 air. The choke coil connects the output of the multiplier rectifier circuit M and the phase terminal.
al).

The power supplied at high voltage is relatively low. Furthermore, the DC discharge from the multivoltage rectifier circuit M occurs only every half-wave in voltage.

The air cleaning device according to this embodiment can be manufactured at low cost. The cheapest part is the casing.

By using the air purifying device according to this embodiment, the increase in the oxygen content in the room is less than 6-8%.

The air purifying device according to the present invention can be modified in various ways without departing from the gist of the present invention, and can be mainly applied to aircraft, automobiles, hospitals, etc. Moreover, the cleaning device can also be applied for industrial use or offices. When used as a labor station, the cleaning device improves the atmosphere for employees. Also, it is easy to install as it does not require ventilation ducts. Furthermore, no temperature loss occurs. The cleaning device kills only viruses and bacteria, thereby improving the shelf life of meat in bacon factories and the like.

〔Effect of the invention〕

According to the present invention, it is possible to provide an air cleaning device that can more effectively sterilize air and neutralize ozone.
