  • Patent number: 9086341
    Abstract: A multi-filter PM 10-PM 2.5 sampler which enable the simultaneous collection of four PM 10 and four PM 2.5 samples is disclosed. The sampler is provided with a PM 10 impactor to remove coarse particles and operates at 33.4 L/min. After the PM 10 impactor, the aerosol flow is divided by half by a branch pipe. Half of the flow is directed into four PM 10 cassettes, while the other half is directed into four PM 2.5 cassettes after the aerosols are further classified by a PM 2.5 impactor. To ensure the aerosol flow uniformly passes through each of the four PM 10 or four PM 2.5 cassettes, an orifice plate is assembled behind each of the filter cassettes to increase the pressure drop, such that the flow rates of eight sampling lines are nearly equal.

    Abstract: A smoke evacuator that draws smoke generated during a medical surgical procedure away from the site at which the smoke is generated. The smoke evacuator includes a pump that draws air into a filter. A sensor internal to the filter monitors the smoke in the air stream drawn through the filter. Normally the pump runs at a low speed, a speed sufficient to draw some air in the filter. When the sensor detects the presence of an appreciable amount of smoke in the air stream the sensor sends a signal indicating the air stream is in this state to the pump controller. The controller then increases the pump speed to result in a like increase in the volume of air drawn through the smoke evacuator. Since the sensor is contained in the filter, a new sensor is installed in the system each time a new filter is installed.

  • Publication number: 20140260993
    Abstract: A multi-phase separation apparatus shapes fluid flow in a flow shaping line preferably shaped to have a plurality of loops with consecutively decreasing diameters. Shaping the two-phase flow drives the heavier, denser fluids to the outside wall of the flow shaping line and allows the lighter, less dense fluids such as gas to occupy the inner wall of the flow shaping line. With the gas positioned on the inner wall, an exit port on the inner wall permits a majority, if not all, of the gas, along with a minimal amount of liquid, to be diverted to a conventional gas-liquid separator at a flow rate much lower than the total flow rate within the flow shaping line. The remaining liquid flow in the flow shaping line is subsequently introduced into an adjustable phase splitter to separate different liquid components from one another.

  • Publication number: 20140033926
    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.

  • Publication number: 20130276627
    Abstract: The invention is directed to a dust removal system, an image capture device and a dust removal vibration method thereof. The dust removal system includes a vibration generation module having a vibration unit which is arranged on a transparent object of an image capture device, and is driven to generate a vibration for dust removal, a vibration detection unit arranged on the transparent object and transform a vibration amplitude into a corresponding electrical signal so as to output a feedback signal continually, a compare unit outputting a control signal when the compare unit determines the feedback signal exceeds the threshold value, and a control unit controlling the vibration generation module based on the control signal to generate the corresponding vibration for dust removal. Thereby, an amplitude of the transparent object can be precisely obtained and the vibration can be precisely adjusted.

  • Patent number: 8535402
    Abstract: A particle reduction system and method is disclosed having an air stream accelerator, a feeder assembly, a variable speed wheel lock operably associated with the feeder assembly for releasing raw material into a conveying air stream created by the positive displacement pump, and a particle conditioning assembly. The raw material is carried by the conveying air stream through the particle conditioning assembly, where particle of the material are collided with each other for the purpose of reducing the size of the particles. In some embodiments, a non-thermal drying system can be used to extract moisture from the raw material. The moisture/solids separation occurs, in large part, due to a head-on collision of two conveying air streams. The collision creates a large squeezing force, much higher than a centrifuge or filter. This impact squeezing acts to squeeze the moisture out of the raw material.

  • Patent number: 8529661
    Abstract: A method and apparatus for removing fine particulate matter from a fluid stream without interrupting the overall process or flow. The flowing fluid inflates and expands the flexible filter, and particulate is deposited on the filter media while clean fluid is permitted to pass through the filter. This filter is cleaned when the fluid flow is stopped, the filter collapses, and a force is applied to distort the flexible filter media to dislodge the built-up filter cake. The dislodged filter cake falls to a location that allows undisrupted flow of the fluid after flow is restored. The shed particulate is removed to a bin for periodic collection. A plurality of filter cells can operate independently or in concert, in parallel, or in series to permit cleaning the filters without shutting off the overall fluid flow. The self-cleaning filter is low cost, has low power consumption, and exhibits low differential pressures.

  • Publication number: 20130055890
    Abstract: An apparatus is configured for filtering a cooling duct of a battery for an electric vehicle. More specifically, a dust sensor is installed in the cooling duct through which cooling air is introduced into the battery for the vehicle and a variable filter is installed in the cooling duct to filter the cooling air and open/close the cooling duct via a driving unit. A control unit configured to control the driving unit according to a signal or sensing value from the dust sensor and a measured temperature of the battery. In particular, when dust is not detected, the cooling duct is fully opened by folding the variable filter. If, however, dust is detected an opening degree of the variable filter is adjusted to close or at least partially close the cooling duct according to the temperature of the battery.
