Abstract
Abstract A mist separator comprising a fine fiber layer or particle layer formed by overlapping single fibers equivalent to or smaller than fine particles contained in gases and imparting hydrophilic property and affinity for oil to said layer based on capillary condensation, thereby to form fine liquid particles into large drops by forcing them to adhere to the fiber layer continuously and the final layer filter medium of a filter element constructed of multilayer media is extended downward from an outer cylinder, as shown in the accompanying drawing, to increase the area of the gas outlet of said filter element by the amount corresponding to the area of the lateral side surface of the extended medium in addition to the forward front area thereof, thus preventing liquid drops splashed from being carried away by the gas flow when liquid drops are to be separated from the final filter medium into a drain trap.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
114 words
A MIST SEPARATOR COMPRISING A CONTINOUS FINE FIBER LAYER FORMED BYY OVERLAPPING SINGLE FIBERS HAVING A DIAMETER IN THE RANGE OF 0.1 TO 0.5 MICRONS WHICH RANGE IS THE EQUIVALENT OF THE MISTS TO BE SEPARATED AND WITH SAID FIBERS FORMING SLITS THEREBETWEEN HAVING A WIDTH NOT GREATER THAN THE DIAMETER OF SAID FIBERS, SAID FIBER LAYER BEING FORMED OF A PLASTIC MATERIAL HAVING A HYDROPHILIC PROPERTY AND AN AFFINITY FOR OIL BASE ON CAPILLARY CONDENSATION SO THAT FINE LIQUID PARTICLES ARE FORMED INTO DROPS BY FORCING THEM TO ADHERE TO SAID FINE FIBER LAYER CONTINOUSLY, AND SAID FIBER LAYER BENT INTO A PLEATED CHRYSANTHEMUM SHAPE TO INCREASE THE AREA OF AIR PASSAGE THERETHROUGH.

Claim 3
Dependent Claim
110 words
A mist separator, as set forth in claim 1, characterized therein by a casing having an inlet and an outlet spaced from said inlet, wall means defining a flow path through said casing from said inlet to said outlet, a coalescer element located in said flow path, said coalescer element comprising a pre-filter on the upstream side of said coalescer element, a layer of said overlapping single fibers located on an extending continuously across the downstream side of said pre-filter, and a supporter for said layer of overlapping fine fibers, and a separating layer formed of said overlapping fine fibers located in said flow path downstream of said coalescer element.
Claim 4
Dependent Claim
43 words
A mist separator, as set forth in claim 2, wherein said coalescer element is arranged vertically above said separate layer, sAid inlet located below the upper end of said coalescer element, and the lower end of said separating layer located below said outlet.
Claim 5
Dependent Claim
21 words
A mist separator, as set forth in claim 2, wherein said casing comprises a removable cover for replacing said coalescer element.
Claim 6
Dependent Claim
162 words
A mist separator comprising a casing having an inlet and an outlet spaced from said inlet, an upwardly oriented outer cylinder located within said casing in the path of flow from said inlet to said outlet, a filter element positioned within said outer cylinder, said filter element comprising an outlet layer filter medium constructed of multi-layer media and located within and extending downwardly from the lower end of said outer cylinder by a length at least approximately equal to the radius of said cylinder for increasing the area of the gas outlet of said filter element by an amount corresponding to the area of the lateral side surface of said downwardly extending medium in addition to the lower area thereof thus preventing liquid drops splashed from being carried by the gas flow when liquid drops are separated for flow downwardly from the lower end of said outlet filter medium, and a pre-filter located in said cylinder above said outlet layer filter medium.
Claim 7
Dependent Claim
162 words
A mist separator comprising a casing having an inlet and an outlet spaced from said inlet, an upwardly oriented outer cylinder located within said casing in the path of flow from said inlet to said outlet, a filter element positioned within said outer cylinder, said filter element comprising an outlet layer filter medium constructed of multi-layer media and located within and extending downwardly from the lower end of said outer cylinder by a length at least approximately equal to the radius of said cylinder for increasing the area of the gas outlet of said filter element by an amount corresponding to the area of the lateral side surface of said downwardly extending medium in addition to the lower area thereof thus preventing liquid drops splashed from being carried by the gas flow when liquid drops are separated for flow downwardly from the lower end of said outlet filter medium, and a pre-filter located in said cylinder above said outlet layer filter medium.
