  • Patent number: 10625197
    Abstract: A vibrating wet precipitator is designed to remove particulates from particulate-laden hot gas. The precipitator includes an array of vertical wet cords stretched within a duct. The cords are tuned to vibrate due to the gas flow by controlling key parameters such as gas flow, velocity, cord length and diameter so that particulate collection and heat transfer efficiency are maximized. The cords are part of sieves. A plurality of these sieves are arranged to define a plurality of gaps, through which the exhaust flows. The sieves and thus the cords are space so that a vortex from a first cord affects an adjacent cord and subsequently cord. The particles are then absorbed in liquid, which can be passed through a heat exchanger filtered and subsequently reused. Preferably the cord arrangement is designed to allow the cords to vibrate at high frequencies, typically 10 to 100 Hz, to maximize particulate collection.

  • Patent number: 8506662
    Abstract: A proactive steam and mist removal apparatus is employed along a point of application of a rewet or steam shower system to remove excess steam and water droplets to prevent damage to machinery and products. The apparatus includes an internal chamber equipped with cooled baffles that promote condensation and a condensate collection mechanism. A vacuum source draws a stream of ambient steam and water droplets from the environment along a path into the chamber and a projected gas stream directs the stream into the chamber wherein at least a portion of the ambient steam condenses into condensate. The remaining portion of ambient steam is separated into water and cold air that is recycled as the projected gas. Steam and moisture that escape capture into the internal chamber are heated by a hot air blower that raises their relatively humidity so that the dried air dissipates harmlessly into the atmosphere.

  • Patent number: 6616719
    Abstract: An air-liquid separating method and apparatus for compressed air. The high pressure air output from an air compressor is transferred through a transfer tube to pass through the cooling tube of a cooling tank. The cooling tube has a diameter larger than that of the transfer tube so that the high pressure air goes from a smaller room into a larger room and the pressure is relieved. The temperature of the high pressure air is lowered due to relief of the pressure and the pressure of the vapor is, approximately the saturated vapor pressure. The cooled high pressure air is further transferred to an air-liquid separating tank. The temperature of the air is lowered to the dew point due to further relief of pressure. At this time, the vapor contained in the high pressure air is condensed into liquid water which drops onto the bottom of the air-liquid separating tank and separates from the air.

The filter unit or filter of the present invention reduces a load on a harm removing equipment, which in turn lowers the cleaning frequency and markedly prolongs the service life of the equipment.

  • Publication number: 20020134244
    Abstract: A trap for condensable liquids, such as tantalum pentoxide, has a primary trapping chamber surrounding a secondary trapping chamber and a sump connected by a small enough opening to the primary or secondary chamber such that trapped liquid in the sump is effectively isolated from a gas flow through the primary and secondary chambers. Partitions and openings in the primary and secondary chambers enhance condensation while allowing condensed liquid flow that does not clog the primary and secondary chambers against the gas flow.

  • Patent number: 6454824
    Abstract: Apparatus for separating solids from flue gas in a circulating fluidized bed (CFB) boiler comprises plural vertical, impact type particle separators located within the CFB in a plurality of staggered rows. The impact type particle separators employ hung elements supported from fluid-cooled tubes which form a collecting channel, typically U-shaped, which separates particles from flue gases conveyed across the particle separators. By separating the support function from the collection shape required by functional performance considerations, the strength requirements of the material used to form the collection shape are reduced and the strength of the material from which the fluid-cooled support is made is much higher due to the lower operating temperature of the material comprising the fluid-cooled support, thereby permitting the use of lower cost materials.

  • Publication number: 20010052223
    Abstract: A heat-resistant and wear-resistant insertion element or segment of a segmented dip tube suitable for use in a refractory-lined cyclone of a cement clinker production line. The insertion element, is capable of being fabricated and installed with a length greater than 120 cm, and is distinguished by a long service life. The insertion element may be a composite structure made of a metallic carcass or sheet (10) and a metallic mesh with webs (11) forming lattice-shaped openings which are filled with a heat-resistant ceramic composition (12).

  • Patent number: 6322603
    Abstract: An apparatus for separating solids from flue gas in a circulating fluidized bed (CFB) boiler includes a plurality of impact type particle separators mounted vertically to a wall of the CFB. The impact type particle separators being adjacently positioned and horizontally spaced. Each impact type particle separator includes a plurality of vertically mounted cooling tubes connected to a fluid circulating system. A slip fit element surrounds the cooling tubes. A cup shaped configuration is formed by side walls and a back wall. The side walls and back wall have a plurality of separate vertically aligned segments extending along the height of the impact type particle separator. Each vertically aligned segment is connected at its ends to an adjacent segment.

  • Publication number: 20010003892
    Abstract: The present invention has an object to improve the efficiency of collection of solidification constituents and solids in exhaust gas and to prevent early blockage of the filter without damaging the vacuum pump. In an exhaust path 48a, a vacuum pump and exhaust gas filtration device are provided. This exhaust gas filtration device is constituted by a trap device, pre-filter and filter. The pre-filter reduces the exhaust gas flow rate flowing through the interior of the exhaust path by controlling the exhaust gas flow path in the vessel. The aforesaid exhaust path is constituted by connecting this vacuum pump, trap device, pre-filter and filter which are arranged in this order from the side of airtight vessel and connected through piping if required.

  • Patent number: 6176901
    Abstract: In a dust precipitation device for filtration of dust created during crystal growth from a melt, cold surfaces are provided as contact surfaces as a part of the gas control geometry, to which the dust can adhere and thus become separated from the transport gas pumped from the processing chamber. Due to cooling of the flow contact surfaces, for example, by a coolant that is supplied via coolant lines blockable by valves, the dust is filtered very effectively from the transport gas. The extraction device has several precipitation chambers located one behind the other for the passage and filtering of the dust from the transport gas. The individual precipitation chambers are connected to each other so that they can be individually removed from or inserted into the precipitation device, for example, manually.
