摘要:
A device for purifying air from non-desired gases and particles, in the case of nuclear power plants from radiating particles and gaseous iodine, and for extermination of microorganisms and removal from the air. The device includes a purifying chamber through which the air to be purified is arranged to flow. In the structurally grounded purifying chamber ionized air (1) is led to a water dust or vapor which can be oxidized with hydrogen peroxide (6) and by increasing the voltage level of the ionization to produce ozone and to be led further to high voltage operated ion blast tips (8) producing a continuous ion jet, which is directed onto collecting surfaces (9) and taking with it droplets, particulate materials and gaseous components connected to them. The volume of the air to be purified determines the shape and volume of the purifying device.

The invention relates to a device (10) for charging or adjusting the charge of gas-borne particles into a defined charge distribution under utilization of corona discharge in the aerosol space (13). In addition to an appropriate geometry of the charger (10) and the electrodes (20, 22), the voltage waveform and the voltage regulation are of great significance for the result. The application further relates to a method for operating the device.
摘要:
Contaminants in food or pharmaceuticals derived from the handling equipment are detected by known detection devices in product flow by the method of detecting particulate magnetic mineral dispersed in the handling equipment or the film used to wrap the food. The minerals magnetic field is detected and the signal generated thereby causes rejection of the product which contains the contamination. A method of making moulded parts of the handling equipment and wrapping film by incorporation of ferrimagnetic ceramic fillers is disclosed. Compositions for moulding and film extrusion with 10-50% of magnetite and other magnetic fillers with a size range of 0.5-20μ are disclosed.

摘要:
Disclosed is an apparatus and method for controlling an air cleaning. The apparatus includes an air cleaning element (20), a current detector (18), an AC high-voltage generator (15) and a control unit (19) . The air cleaning element (20) generates negative ions and ozone using a plasma discharge and cleans indoor air by the negative ions and ozone. The current detector (18) detects a state of current passing through the air cleaning element (20). The AC high-voltage generator (15) generates an AC high-voltage, and applies the AC high-voltage to the air cleaning element (20). The control unit (19) varies a magnitude of the AC voltage applied to the air cleaning element(20) by the AC high-voltage generator (15) depending on a current detecting signal received from the current detector(18). Therefore, ozone is adequately generated below a limit value depending on a state of indoor air, thereby increasing air cleaning performance so as to sterilize and clean contaminants more efficiently.
摘要:
A method of separating a powder mixture is disclosed. A first magnetic field is applied to the powder mixture which contains a non-magnetic metal powder and a contaminant powder. A field strength of the first magnetic field magnetizes the non-magnetic metal powder and leaves the contaminant powder non-magnetized. A second magnetic field is applied to the powder mixture to separate the magnetized metal powder from the non-magnetized contaminant powder.
