Jet-Venturi scrubbers are also known as ejector scrubbers. Instead of relying on high gas velocity as in the case of high energy Venturi scrubbers, it relies on high pressure jet sprays to entrain and force the gases through the Venturi throat. The high velocity sprays impact and capture the dust particles as the gases converge into the Venturi throat. Meanwhile a zone of intense gas-liquid contact is created to effect absorption of acidic gases. Up to 2" w.c. of available draft can be developed by these scrubbers to pull gases through without the aid of a blower. The scrubbing efficiency depends on the jet spray pressure and the liquid to gas ratio used. Typically, a single stage unit can remove 98-99% of particles over 2 microns and 90-98% of soluble acid gases. |
