医院放射科和照像馆的暗室每天要倒掉很多废定(显)影液。其中溶有氯化银和溴化银,完全可以回收白银,早年本人为医院放射科做了一台以变压器降压梯级调流型白银回收器,回收的白银质量和使用效果尚存缺陷。最近在原机基础上加以改造,制成节能,近似无级调电流,恒压、恒流型白银回收器。电路如下: 工作原理 选用四个(C_1-C_4)不同容量的电容器,利用它的恒流特性和无功耗优点作为降压元件。配 The darkroom in the hospital radiology and photographic laboratories drains a lot of waste fixative (clear) daily. Which dissolved in silver chloride and silver bromide, silver can be completely recovered, early years I made a hospital radiology Step-down transformer step-down converter silver recovery, recovery of silver quality and the use of the remaining flaws. Recently based on the original machine to be transformed into energy-saving, similar to non-current transfer current, constant voltage, constant current silver collector. The circuit is as follows: Operating principle Choose four (C_1-C_4) capacitors of different capacities, make use of its constant current characteristic and non-power consumption advantages as a step-down element.
