Installation for liquid impregnation of timber - has autoclave above receiving tank and vacuum and supply pumps

摘要

An autoclave (A1) for holding the timber to be impregnated is installed at ground level. A reserve tank (RR) of impregnation fluid is mounted above and in communication with it, the liquid flowing into a receiving tank (CR) below ground. On one side, a vacuum pump (PV) is connected to these tanks; on the other side is a pressure pump (PPC), this also being used for circulating the fluid. connected to the reserve tank is a control vessel (RM), maintaining the fluid supply level, and a main supply tank (RS) is connected directly to the receiving tank. The system is designed for a short throughput cycle time.
