Abstract: A biofiltration apparatus and method for reducing methyl bromide concentration in a volume of a gas are disclosed. The apparatus includes a housing and a substrate component located in the housing. The substrate component includes a population of methyl bromide degrading microorganisms. The housing receives a volume of contaminated gas, such as exhaust from a fumigation site, through a contaminated gas inlet. The contaminated gas is exposed to the methyl bromide degrading microorganisms where the methyl bromide is biodegraded. The filtered gas, or the gas with a reduced methyl bromide concentration, is then directed out of the housing. The apparatus may also include a contaminated gas load dampening device.

Abstract: A cell for gas cleaning, preferably for separating gases from solid particles, includes an inlet pipe connected gas-tightly to a casing, and an entrapment pipe mounted within casing downstream of the inlet pipe. An enter opening of the entrapment pipe faces an outlet of the inlet pipe. A free area of the enter opening of the entrapment pipe is larger than a free area of the outlet of the inlet pipe, and smaller than a free area of the passageway of the casing. The cylindrical settling portion of the inlet pipe allows to establish a stationary condition of the dust laden gas flow. Separation is achieved by extension of the stationary dust laden gas flow when it enters the casing through the outlet of the inlet pipe. The stream of the particles does not expand, and almost all the number of the particles travels due to particle inertia toward the enter opening of the entrapment pipe.

Further, an outlet pipe protrudes into the casing through its top. The inlet port is located higher than the bottom end of the outlet port. An externally-driven vane wheel is provided under the outlet pipe in a concentric relationship with respect to the casing.

The baffle (34) is disposed for vertical insertion through an upper wall (18) of the separation chamber (12) of the separator (10) to effect variable occlusion of an annular space (38) defined between a cylindrical wall (14) of the separation chamber (12) and a vortex finder (26) positioned generally centrally within the separation chamber (12). The baffle (34) functions to decrease pressure drop between an inlet (16) to the separator (10) and an outlet (32) from the separator (10).

Abstract: A stream of particle-containing fluid (e.g. from coal gasification or combustion) can be cleaned and split by flowing it into and through the vortex of a cyclone in which an externally adjustable vortex stabilizing means is moved close enough to the outlet opening for the particle-depleted fluid to provide an outflow of such fluid having a selected volume or particle concentration.

Abstract: Both an apparatus and a method for maximizing the separation characteristics of a swirl vane steam-drying device is disclosed herein. Generally speaking, such swirl vane separators include a housing formed from a riser barrel which is concentrically disposed within a downcomer barrel, a steam inlet at one end of the concentric barrels, a steam outlet at the other end of the concentric barrels, and a set of pitched blades disposed within the riser barrel between the steam outlet and inlet for imparting a radial component of motion to the wet steam which flows therethrough. This radial component of motion causes water droplets entrained in the steam to move in spiral paths which ultimately intersect a region in the interior of the separator which includes an opening for directing these droplets into a downcomer path defined between the concentrically disposed riser and downcomer barrels of the housing.

Abstract: An electrostatic precipitator wherein a gaseous carrier medium is caused to pass through one or more electrostatic filters to be relieved of the major percentage of impurities. The thus purified carrier medium is caused to flow through a tapering funnel-shaped section of the outlet wherein the lower layer of the flow is caused to enter an elongated horizontal slit-shaped aperture leading to a chamber which narrows in the direction of flow of carrier medium therein and discharges into a first conduit for evacuation of the lower layer. The upper layer enters a polygonal or cylindrical second conduit at a level above an adjustable flat or otherwise configurated partition which extends into the funnel-shaped section at the intake end of the second conduit and whose inclination can be changed to vary the size of the aperture leading to the chamber.

Abstract: In a pressurized materials processing system, separation of solid particulates from a gaseous process fluid is beneficially accomplished by use of a swept orifice discharger comprised of a cylindrical housing that is closed at one end and open at the other end. The housing contains an impeller within its interior and has a selected, presized orifice in its cylindrical side wall. In operation, the solid material and gaseous fluid are received in the swept orifice discharger housing and the solid material is continuously centrifugally urged toward the housing side wall so that it separates from the gaseous process fluid and collects on the housing side wall.

Abstract: A particulate separator of the concurrent flow type includes an inner cylinder mounted concentrically within a tapered conical outer cylinder which is closed at the outer return end. A fan unit is secured within the return end of the outer cylinder to draw air inwardly through the center cylinder, impart a centrifugal force thereon and imparting a tangential spin to the air moving outwardly and then rearwardly and back through the outer conical cylinder. The particulate matter within the fluid moves outwardly to the periphery of the outer cylinder as a result of centrifugal forces. The tangential spin imparted to the air cause the air to move in spiral return path with the conical cylinder establishing a decreasing cross section.

A gas blast for cleaning the filter cells in a direction to move the pivoted element so that the outlet passage is varied and cleaned.

Abstract: Excess coating material removed from a coated web 1 by an air doctor 6 and entrained in the exciting gas mixture flow 8 is directed along a plate 9 to effect primary coating material separation and recovery in a chamber 11, whereafter the flow passes along an inwardly spiraling apparatus wall 14 which terminates in an air exhaust duct 16. The wall 14 initially continues the prolongation or extension plane of the plate 9, and includes secondary recovery chambers 13 and 15, whereby separation is implemented by both centrifugal and gravitational forces. The same concepts may also be used to recover solid particles in a surface abrasion apparatus such as a sand blaster.

A plurality of spray nozzles spray a washing liquid into the chamber for contact with the contaminated gas therein.
