  • Patent number: 10258056
    Abstract: A filtration system is arranged to safely vent a storage room into which a fog mixture is introduced. Venting the storage room reduces and/or prevents a substantial increase in the internal pressure of the storage room. To control the pressure differential between the storage room and the ambient air pressure, a venting manifold with an in-line duct fan is used, for example, to exhaust storage room air into the atmosphere. The exhausted storage room air is filtered to reduce the exfiltration of chemicals and/or other contaminants from the environmentally sealed storage room.

  • Patent number: 10252208
    Abstract: A filter element for filtering a fluid is provided with a filter bellows made of a filter medium folded along fold edges in a zigzag shape to form folds, wherein the folds extend between oppositely positioned end face edges of the filter bellows. The filter bellows defines a raw side and a clean side of the filter element, wherein a fluid to be filtered flows from the raw side to the clean side. The filter medium has faces that are flowed through by the fluid to be filtered. The filter medium is provided at least on one of the faces that are flowed through with beads extending transversely to the fold edges. In a proper operating state of the filter bellows, the beads effect a flow of at least a portion of the fluid to be filtered in a direction perpendicular to the fold edges.

  • Patent number: 10245595
    Abstract: A high voltage power supply for an electrostatic precipitator comprises a high voltage transformer, a high voltage bridge rectifier and a semiconductor switch controller configured to control an output power level of the high voltage power supply. A control unit (50) is configured to determine a firing angle of firing pulses for the semiconductor switch controller. During normal operation, a peak voltage value is measured and stored in each half period. When a breakdown is detected, a residual voltage (Ur) over the electrostatic precipitator is measured. A firing angle (?1) of a firing pulse to be provided to said semiconductor switch controller in the first half period after the breakdown is determined from the latest stored measured peak voltage value (Ubef) and the measured residual voltage (Ur) based on a predetermined relationship between the firing angle (?1) and said measured voltages.
