摘要： The present invention provides a spray-drying granulation apparatus having a chamber comprising (a) an upper section which is a spray-drying section for spraying a feed solution from a nozzle and drying the formed droplets with hot air and (b) a lower section which is a fluidized granulation section, in which apparatus there is used, as the nozzle for spraying a feed solution, a two-fluid pressure nozzle comprising a centrifugal pressure nozzle for spraying a feed solution and a cylindrical pipe for blowing out a high-speed gas, provided around the centrifugal pressure nozzle. This spray-drying granulation apparatus enables spraying of even a feed solution of large volume with only one nozzle. Further with the two-fluid pressure nozzle of the apparatus, there is no need of replacement of nozzle parts when the feed rate, concentration, viscosity, kind, etc. of the feed solution are changed greatly, because the diameters of droplets formed by spraying can be controlled by controlling the speed of the high-speed gas, while in the conventional nozzles the replacement of nozzle parts such as orifice, core and the like has been necessary when the above change is made.
摘要翻译：本发明提供了一种具有腔室的喷雾干燥造粒装置，其包括（a）上部，其是用于从喷嘴喷射进料溶液并用热空气干燥所形成的液滴的喷雾干燥部分，（b）下部作为喷射给料液的喷嘴的流化制粒部，使用包括用于喷射进料溶液的离心压力喷嘴的二流体压力喷嘴和用于吹出高速运转的圆筒状管气体，围绕离心压力喷嘴提供。这种喷雾干燥造粒装置能够仅喷射一个喷嘴即可喷射大量的进料溶液。此外，当装置的双流体压力喷嘴，当进料溶液的进料速度，浓度，粘度，种类等大大改变时，不需要更换喷嘴部件，因为喷雾形成的液滴的直径可以通过控制高速气体的速度来控制，而在常规喷嘴中，当进行上述改变时，需要更换诸如孔，芯等的喷嘴部件。

摘要： A method and apparatus of cooling incinerator exhaust gas for a cleaning treatment of high temperature exhaust gas discharged from an incinerator of refuse and/or waste in a post-step are provided. A spray cooling chamber includes a chamber having a lower end portion formed into a nearly cylindrical shape of an inverted conical shape, a gas distribution chamber equipped with a revolving blade, arranged at an upstream side of the chamber, a sprayer of a cooling liquid arranged at central upper portion of the chamber, a dust exhaust port arranged at the lower end portion of the chamber, and an exhaust pipe arranged on the chamber. Waste heat recovery from exhaust gas is limited to a temperature range capable of suppressing generation of dioxins, and high temperature exhaust gas is rapidly cooled, particularly at a temperature drop rate such that the vicinity of 300.degree. C. is dropped in a short time within 1 second, so that exhaust concentration of dioxins from an incinerator plant can be decreased to 0.1 ng-TEQ/Nm.sup.3 or less.

摘要： Process for producing microcapsules. Wax or a mixture of wax and protein is dissolved in a mixed solvent consisting of an organic solvent and water, the surfaces of particles of a core substance are wetted with the resulting solution at temperatures of 45 deg.C or below to selectively deposit the wax or the mixture of wax and protein on the particle surfaces and allow them to coat the particle surfaces. And then a slurry containing the particles is subjected to a solvent removal treatment.

摘要： The injection type nozzle of the present injection is a two-fluid pressure nozzle comprising a centrifugal pressure nozzle for spraying a feed liquid and a cylindrical pipe for blowing out a high-speed gas, provided around the centrifugal pressure nozzle, said two-fluid pressure nozzle having a tapered structure at the front end portion and said cylindrical pipe for blowing out a high-speed gas, having air-purging through-holes at the front end portion. The spray dryer of the present invention comprises a drying chamber, the above two-fluid pressure nozzle provided at the bottom of the drying chamber with the nozzle tip directed upward, an inlet for feeding a hot gas into the drying chamber, and an outlet for driving an exhaust gas out of the drying chamber. The spray dryer employing a closed system according to the present invention comprises a drying chamber, the above two-fluid pressure nozzle provided at the bottom or top of the drying chamber with the nozzle tip directed upward or downward, an inlet for feeding a hot gas into the drying chamber, and an outlet for driving an exhaust gas out of the drying chamber, in which spray dryer the hot gas for drying fed into the drying chamber and/or the high-speed gas for atomization is fed by circulating the whole or part of the exhaust gas after spray drying. In the two-fluid pressure nozzle of the present invention, diameters of droplets formed can be controlled by controlling the flow speed of the high-speed gas for atomization.
