摘要： In conventional fluidized granulators whose housing is made of a steel plate, a powder tends to cause blocking if it is highly hygroscopic, and the bag filter used therein causes clogging. These problems have been solved in the present invention by forming the housing of a fluidized granulator with a porous membrane in place of the conventional steel plate. This fluidized granulator produces granules or a coated powder by spraying powder with water, a binder fluid or a coating fluid while maintaining the powder in a fluidized state.
摘要翻译：在壳体由钢板制成的常规流化制粒机中，如果吸湿性高，则容易引起堵塞，并且其中使用的袋式过滤器导致堵塞。在本发明中通过用多孔膜代替常规钢板形成具有多孔膜的流化造粒机的壳体，已经解决了这些问题。该流化造粒机通过在将粉末保持在流化状态的同时，用水，粘合剂流体或涂布液喷洒粉末来产生颗粒或涂覆的粉末。

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： A spray-drying granulation apparatus having: a spray drying section formed in an upper position of a chamber wherein sprayed feed liquid particles are dried to powder by a hot-air; and a powder granulation section formed in a power position of the chamber, and provided with a nozzle for feeding a binder liquid. There is no need of maintaining sticky powder or completely dried powder to the lower section. The sprayed particles can be dried to powder in a wide drying range before they are granulated in the granulation section by a binder liquid. The degree of granulation can be selected as desired while preventing attachment of powder to the inner wall of the chamber due to incomplete drying.

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。
