Abstract
The contact plate for mass-exchange apparatus consists of two disks facing each other with their end surfaces and capable of mutual rotation round the axis thereof. Each disk has one slit-like hole shaped as an Archimedean spiral so that when one disk rotates with reference to the other said holes overlap each other.
Claims2
A contact plate for a mass-exchange column, comprising:
- two coaxial planer disks with their end faces facing each other and in close proximity, each of said disks being capable of rotation about their common axis, a hole being formed in each of said disks as a slit in the shape of an Archimedean spiral whose centre coincides with the centre of said disk, said slit extending continuously through the whole of the disk, said hole in one of said disks being in alignment with the corresponding hole in the other of said disks, thereby when one of said disks rotates with respect to the other disk said holes at least partially overlap each other and control the flow rate of reactant materials through the plate.
