decontamination

The invention relates to a process of treating objects, particularly of cleaning and decontaminating or disinfecting or sterilizing objects. A plasma processed gas (PPG) is provided, and by contacting this plasma processed gas (PPG) with a liquid, a sterilizing gas and a sterilizing liquid are generated. The objects to be treated are contacted with the sterilizing liquid in a first treatment step and with a treatment gas in a second treatment step, wherein the treatment gas can be the sterilizing gas or the plasma processed gas (PPG).

The present invention relates to a device for plasma-treating hollow bodies, such as bottles, vials, syringes, shut-off caps, etc., in particular with a view to sterilising said hollow bodies, and is equally suitable for various discharge types such as dielectric barrier discharge and discharges with high frequency and microwave excitation.

The invention relates to a method and to a device for quickly decontaminating and sterilizing preferably thermolabile goods using a plasma gas that is preferably generated from air as a process gas, with the subsequent humidification of said plasma gas with water.

The invention relates to a process for textile cleaning and disinfection by means of plasma and plasma lock for inactivating viruses, bacteria and spores and also for purifying air in the conventional sense, such as to remove dust, pollen, odours or the like. The object of the invention is to develop a process for cleaning and disinfection of textiles and air to remove viruses, bacteria, spores and also for cleaning to remove dust, pollen, odours etc., in which the use of water and diverse cleaning agents and also disinfectants is not necessary, or can be significantly reduced.

The present invention relates to an apparatus for igniting and generating a propagating, diffuse microwave plasma. The device is suitable for generating microwave plasmas for the purpose of plasma treatment of surfaces and substances, in particular of three-dimensional objects as well as of particles under atmospheric pressure.
The solutions according to the invention are presented in the claims.

The invention relates to the field of plasma cleaning of exhaust gases and exhaust air.

The invention relates to a device for generating a cold, HF-excited plasma under atmospheric pressure conditions, comprising a metal housing functioning as a grounded electrode in the region of the emergent plasma, wherein an HF generator, an HF resonance coil having a closed ferrite core suitable for the high frequency, an insulating body acting as a gas nozzle, and a high-voltage electrode mounted in the insulating body are disposed in such a manner that they are permeated or circulated around by process gas.

A plasma tool for generating a cold plasma beam (10) is described. The plasma tool is defined by the fact that it has a plasma nozzle, in particular a plasma nozzle which is dimensioned for operation by hand, wherein at least the coil (6) of the adaptation network is integrated into the plasma nozzle, for operation with a high frequency generator in addition to the capacitor C2, while the capacitor C1 can be arranged in the generator itself or in its vicinity.

The invention relates to a method for treating fluids (5) by producing corona discharges (12) in the fluid volume (6). According to said method, high-voltage pulses (8) are applied to an electrode arrangement (2) present in the fluid volume (6). Pulse rise times of the high-voltage pulses (8) are in the range of 1 to 40 nanoseconds and pulse duration of the high-voltage pulses (8) is in the range of 50 to 400 nanoseconds.

The present invention relates to a device as well as a system and a method for treating an object, in particular one or more free-form objects, with plasma. The object to be treated can in particular be a raw food such as an egg, fruit or vegetable, or packaging as well, or respectively a cap, etc. Treating the object with plasma preferably serves the object of decontaminating and sterilizing the surface of the object.
