A prewetting apparatus for mixing dry material with a liquid before mixing. The wetting apparatus has a cylindrical upper chamber mounted above a lower mixing chamber. The lower mixing chamber has a conic surface with an outlet below. Pressurized liquid is introduced from a housing which extends circumferentially about an upper portion of the lower section. Liquid is introduced through apertures into a groove at the upper edge of the conic surface at a predetermined flow rate and pressure so as to swirl helically down the conic mixing surface to exit at the outlet. Dry particulate matter is metered through an inlet formed in the upper cylindrical portion and is dropped at a predetermined rate into the liquid swirling in the mixing section.

Apparatus for ejecting a mixture of liquids, e.g. urethane foam, comprises a cylindrical chamber into which the liquids are separately introduced under pressure and mixed and ejected from the open end of the chamber. A reciprocable plunger alternately exposes the inlets in its rear portion and seals the inlets from each other and purges the chamber in its forward position. The inlets are axially spaced apart and separated from each other by a throat that has interference fit with the plunger in the forward position of the plunger, the plunger having for this purpose an elastic deformable surface.

An improved fluid mixing device comprised of a plurality of stacked, relatively thin plates having fluid passage means therein to allow two or more fluids to pass therethrough and to be mixed with each other yet at least one of the fluids, in the form of a liquid, can be atomized to enhance the mixing action between the two fluids. The device is constructed so that one or both fluids can be used to cool the face plate of the device such as when the latter is adjacent to a combustion chamber. Various embodiments of the device are disclosed.

The invention concerns a process and an apparatus for continuously producing chlorine dioxide, the process comprising the steps of: feeding chlorate ions, acid and hydrogen peroxide as aqueous solutions to a reactor; reducing chlorate ions in the reector to chlorine dioxide, thereby forming a product stream in the reactor containing chlorine dioxide; feeding motive water to an eductor comprising a nozzle; bringing the motive water to flow through the nozzle and causing it to flow further through the eductor in an at least partially spiral or helical manner, transferring the product stream from the reactor to the eductor and mixing it with the motive water and thereby forming a diluted aqueous solution containing chlorine dioxide, and; withdrawing the diluted aqueous solution containing chlorine dioxide from the eductor.
摘要:
A method and apparatus for homogenizing and micronizing aerosol formulations. The method includes the steps of homogenizing and micronizing an aerosol formulation at ambient temperature in a closed apparatus where the entire apparatus is maintained under elevated pressure. The apparatus includes a closed loop containing a reaction vessel, a homogenizer and a fluid conduit interconnecting the reaction vessel and the homogenizer. The homogenizer includes an interaction chamber and an intensifier pump. The interaction chamber includes a stream splitter for separating a stream of aerosol formulation components into two streams and an impaction chamber for recombining the stream.
摘要:
A method for spraying starting material particles in a continuous hydrothermal reaction, comprising spraying an aqueous fluid pressurized and heated in excess of the saturated vapor temperature and a starting material slurry pressurized at ordinary temperature. A starting material slurry feed orifice is provided in a central portion of an aqueous fluid spray orifice to spray and mix the aqueous fluid and the staring material slurry. In order to avoid entry of heat into the starting material fluid from the aqueous fluid, a heat-insulating layer is provided between feed paths for the respective two fluids. According to the above method, the starting material slurry is sprayed particularly under subcritical to supercritical conditions beyond the saturated vapor temperature to form fine particles without agglomeration thereof, whereby a hydrothermal reaction can be continuously and efficiently effected.
