Abstract
There is disclosed a process and apparatus for withdrawing an exhaust stream including gas, liquids and solids from the dental operatory connected to the suction side of a vacuum pump wherein solids and liquids are sequentially removed such that compressed gas from the vacuum pump is passed through a heat exchanger for cooling, thus permitting the use of lightweight, less expensive conduit piping for a vent exhaust conduit.
Claims2
Apparatus for treating a waste stream from a dental operatory which comprises:
- means for compressing a gaseous stream having a suction inlet port and a compressed gas outlet port;
- conduit means for withdrawing said waste stream from said dental operatory in fluid communication with said suction inlet port of said means for compressing a gaseous stream;
- heat exchanger means including an inlet port and an outlet port for cooling a gaseous stream;
- conduit means in fluid communication with said compressed gas outlet port of said means for compressing a gaseous stream and said inlet port of said heat exchanger means;
- conduit means for venting to atmosphere a gaseous stream exiting said outlet port of said heat exchanger means.
