摘要： The liquid to be atomized is uniformly sprayed on the inner surface of a hollow rotating cylinder, for example by means of single- or two-substance nozzles and is thus distributed on bores provided in the cylinder wall. The rotation of the cylinder causes the liquid to flow outward through the bores. Droplets are generated when the liquid flows out of the bores by laminary decomposition of the jet. The flow rate in each bore lies in the range rho / sigma ) 200 of bores having the diameter DB in the cyllynder wall causes the flow rate of liquid through each bore to be relatively low, so that a continuous laminary flow in each bore is ensured even at low viscosities and technically useful total flow rates. Preferably cylindrical bores with a minimum length at least three times greater than the bore diameter are provided in the cylinder wall, with a narrow spacing in the range defined by 1.1

摘要： A compacting granulator for continuous, compacting granulation comprises a substantially horizontal rotatable drum, through which an eccentric shaft extends, which carries compacting means which partly transfer substantial amounts of energy to the granulate possible for attainment of a high degree of compacting, partly hurl up the material under treatment, so that the material, while hurled up, is brought in intimate contact with a treatment liquid sprayed through the nozzle. A stationary scraper as well as nozzles with individual feed supply ensure great flexibility and a reliable operation.

摘要： A filter unit (1) has a plurality of filter elements (7) extending from a plate (6, 32) which divides the unit into a lower inlet side (9) for gas carrying product and an upper outlet side (8) for filtered clean gas. A cleaning-in-place of the filter elements is performed by supplying cleaning liquid in a sequence of several separate liquid pulses which are mixed with the pressurized gas pulses. The ejection of the individual pulse of pressurized gas is initiated at the earliest simultaneously with or after initiation of ejection of the corresponding pulse of cleaning liquid.

摘要： In fluidized spray drying of a feedstock to produce an agglomerate product by means of at least one spraying device (7) arranged in the upper part (2) of a vertically disposed drying chamber (1), in a lower part of which a fluid-bed is accommodated, a drying gas introduced into a processing zone (16) of the chamber (1) is exhausted through an integrated arrangement of filter elements (11) in the upper chamber part (2) to retain and allow agglomerationof the particles carried by the flow of drying gas on the filter elements (11). By intermittent supply of reverse flow gas pulses to the filter elements (11) the retained particles are released and returned to agglomeration zones (16, 17). The drying gas is introduced at a rate producing at the filter walls (13) a flow rate amounting to at least 150 cubic meters per hour per square meter of filter wall surface. In the non-operative condition of the spray drying apparatus the filter elements (11) may be cleaned-in-place by supplying a cleaning liquid to the interior of the elements.

摘要： A fluid bed dryer comprises a bed plate (12) defining openings or perforations (22) therein, means (16) for feeding a pulverulent or particulate product (P) to the bed plate (13), means (12, 14) for directing fluidizing gas flows upwardly through said openings or perforations (22) so as to fluidize the product fed thereto, and means (17, 19) for discharging product (p) from the bed plate (13). The bed plate (13) comprises at least one bed plate section, each of which is divided into elongated zones (32, 34-36) extending substantially between first and second positions of the plate section. First and/or second pluralities (22b, 22a) of the openings or perforations (22) are substantially uniformly distributed over the area of each of at least some (34-36) of said zones and are directed and shaped so as to impart to the fluidizing gas flows a flow component which is directed generally towards said first and second positions, respectively. The number of the second plurality of openings (22a) in one zone (35) exceeds that of the other (34, 36), whereby the resulting transporting component of the fluidizing gas flows may be adjusted as desired by choosing proper proportions of the number of the first and second pluralities of openings in adjacent zones.

摘要： In a method of providing a brief heat treatment to a liquid by mixing steam therein followed by flash cooling at reduced pressure, very short and easily adjustable holding time at elevated temperature is obtained by adjustable increase of the amount of steam injected into the liquid to amounts exceeding those which condense by contacting the liquid. The method is efficient for heat treatment, such as sterilization, of heat sensitive materials including food products of high viscosity.

摘要： The mercury removal capability of a flue gas purification system is improved by introducing sulfur vapors into the flue gas stream where admixed flue gases and sulfur vapors contact solid particulate materials in the flue gas. The solid particulate materials adsorb mercury and sulfur vapors and catalyze reactions forming solid products comprising mercury. The solid products comprising mercury are separated thereby forming a purified flue gas stream.

摘要： A process for treating a gas such as desulfurizing a flue gas. The process includes comminuting calcium oxide in a flowing first gaseous medium containing water in a comminuting zone to form particulates of calcium hydroxide suspended in the first gaseous medium. The particulates in the first gaseous medium are contacted with a second gaseous medium containing at least one acidic moiety reactive with said calcium hydroxide in a recirculating reaction zone for a time sufficient to obtain reaction between the calcium hydroxide and the acidic moiety to produce a solid reaction product. A third gaseous medium including particulates and solid reaction products is withdrawn from the reaction zone and at least some of the solids from the third gaseous medium are separated and at least a portion of the separated solids are recycled to at least one of the reaction zone and the comminuting zone.
