    • A paint spray booth with a filter and means within the spray booth to incinerate paint from the filter. A filter particularly adapted for collecting paint overspray in a paint spray booth. The filter has a plurality of members with a first portion parallel to the path of the air and paint particle flow which is to be filtered, each of the members having a second portion extending normally in a first direction from the downstream side of the first portion. The second portions of the members are spaced from each other and form openings therebetween on a plane normal to the flow of air and paint particles. Each of the members has a third portion extending from the other side of first portion and in the opposite direction from the second portion, and the third portions of the members form slots between members with areas less than the area of the downstream openings. Each of the members also having a fourth member extending perpendicularly from the end of the second member opposite the first member toward the third member, and a fifth member extending perpendicularly from the end of the third member opposite the first member and away from the first member.
    • 喷漆室内有一个过滤器和喷雾室内的装置,用于从过滤器中焚烧油漆。 特别适用于在喷漆室中收集油漆过喷的过滤器。 过滤器具有多个构件,其具有平行于要被过滤的空气和涂料颗粒流的路径的第一部分,每个构件具有从第一部分的下游侧沿第一方向正常延伸的第二部分 。 构件的第二部分彼此间隔开,并在垂直于空气和油漆颗粒流动的平面上形成开口。 每个构件具有从第一部分的另一侧和与第二部分相反的方向延伸的第三部分,并且构件的第三部分在具有小于下游开口的面积的区域的构件之间形成槽。 每个构件还具有从第二构件的与第一构件相对的端部垂直于第三构件延伸的第四构件,以及第五构件,其从第三构件的与第一构件相对的端部垂直地延伸并远离第一构件 。

    • An anti-pollution ventilation system includes means for circulating a fluid in a closed-loop path outside of a spray-type coating chamber. The circulating fluid is directed so as to form a fluid curtain across entrance and exit openings of the coating chamber. The system also includes a separator for continuously separating coating material from the circulating fluid. The separator comprises a plurality of side-by-side bores, having helical baffles therein, through which circulating fluid is directed. In one embodiment of the invention, some of the bores can be selectively closed. Means are included for transporting separated coating material from the separator back to the coating chamber for reuse. One refinement of the invention is to provide a bleeding means for bleeding fluid from the ventilation system, and another refinement is to provide a leakage collecting means for collecting leakage from the fluid curtains; in both cases a vapor-contaminant cleaner is provided to clean drained or leaked fluid before it is released to outside atmosphere. The ventilation system of this invention is further disclosed in combination with an irradiation type coating device wherein a coating chamber and an irradiating oven are located so close to one another that their inner atmospheres can mix. The inner atmospheres comprise mainly inert gases. In this embodiment, inert gas is bled from the ventilation system and fed to the irradiation oven.
    • 防污染通风系统包括用于使流体在喷雾式涂覆室外部的闭环路径中循环的装置。 循环流体被引导以在涂覆室的入口和出口开口形成流体窗帘。 该系统还包括用于从循环流体连续分离涂层材料的分离器。 分离器包括多个并排孔,其中具有螺旋挡板,循环流体通过所述并排孔。 在本发明的一个实施例中,一些孔可以选择性地关闭。 包括用于将分离的涂层材料从分离器输送回涂覆室以重新使用的装置。 本发明的一个改进是提供一种用于从通气系统中渗出液体的渗血装置,另一个改进是提供一种用于从流体窗口收集泄漏的泄漏收集装置; 在这两种情况下,提供蒸汽污染物清洁剂,以便在释放到外部大气之前清洁排出或泄漏的流体。 本发明的通气系统进一步与照射型涂布装置相结合,其中涂覆室和照射烘箱彼此靠近,使得它们的内部气氛可以混合。 内部气氛主要包括惰性气体。 在该实施例中,惰性气体从通风系统排出并进料到照射烘箱。
