A cooling system with at least one cooling tower and multiple upper pans or distribution manifold pipes is provided with a strainer tank assembly at the tower lower end in proximity to the sump to receive incoming fluid for cooling, which strainer tank includes a screen to strain particulate material from the inlet fluid communicated to the tower upper end and to equally distribute this fluid at the lowest elevation at a pressure with a higher static pressure component than its dynamic pressure component to avoid a requirement for a flow control valve to provide relatively quiescent fluid for fluid distribution to the tower and fluid transfer media therein. A pressure relief baffle in the strainer tank is operable in response to a fluid overpressure condition to bypass the screen and open fluid communication to avert catastrophic failures within the fluid circuit.

Method and apparatus for thermal storage improved to deliver cold liqud refrigerant during a supply cycle by freezing storage liquid envelopes only on tubes defining refrigerant flow paths during an ice production and storage cycle and extending the effective flow paths during the supply cycle through supplementary conduits immersed in free storage liquid which is chilled by the exterior of the frozen envelopes.

The invention relates to improved sealing means for shell and tube heat exchangers which means use only components which are external to the heat exchanger shell to mechanically compress a series of rubber type gaskets and incompressible tube sheets to thereby seal the tube to tube sheet joints and the tube sheet to shell joints in such a manner as to precisely control the degree of compression of the rubber type gaskets and eliminate the need for the retightening of bolts by the use of confining elements on the outer periphery of said gaskets.

A belt-drive assembly for use on air-moving systems in corrosive atmospheres comprising a larger non-metallic driven sheave in conjunction with a smaller metallic driver sheave wherein the metallic sheave may be located in a vented enclosure is disclosed. This arrangement prevents corrosion of the drive system and prolongs belt life.

A contact body or evaporative heat and mass exchanger packing composed of a plurality of side-by-side thin sheets interlocked with one another. The sheets are grooved with a serpentine-like, continuously-variable, cross section form to produce a plurality of liquid and gas channels between the sheets. The sheets have integrally-formed knobs and sockets specifically located to provide up-spaced alternate sheet support without utilizing adhesives of any type. The sheets are preferably composed of a thermoplastic material of any desired length, being continuously pressure-vacuum formed from long sheet rolls. The groove crests abut adjacent sheets apices at continuously-variable spacings of both greater and lesser dimension than the basic edge spacing of the serpentine grooves. The flat crests or apices of grooves are also infinitely variable in width dimension while maintaining a constant sidewall groove angle. The individual sheets are rotatably oriented to provide ideal bottom edge alternate sheet displacement for enhancing fluid flow.

This invention involves spaced, horizontally extending corrugations, spaced, vertically oriented film surface sheets. The surface of the fill is enhanced by molded-in angular grooves to define discrete water passageways and air turbulation ridges.

A counterflow evaporative heat exchanger comprises a vertical conduit in which a coil assembly is positioned. A fluid to be cooled or condensed passes through the coil assembly while water is sprayed downwardly over it and air is blown upwardly through it. The coil assembly comprises a plurality of tubes which at each level in the assembly are spaced apart from each other in the horizontal direction by an amount greater than the diameter of the tubes. This has been found to improve heat transfer in comparison to counterflow evaporative heat exchangers using closely packed coil assemblies.

The invention relates to an improved U-shaped splash bar fill configuration for use in crossflow cooling towers.

U-Bar Fill

An air pumping and scrubbing apparatus which is suitable for use in spray paint booths is described. This apparatus uses liquid sprays directed into a conduit to cause an air pumping action to inject air into the conduit and dis-discharge to atmosphere using water pressure to move the air so as to avoid the necessity for any moving parts or electrical corrections in and around the air stream. The liquid sprays impinge on mist eliminator strips and are recovered along with foreign material from the air while the air is exhausted downstream of the strips. A novel transfer plate arrangement is provided between the strips and a sump to minimize foreign material buildup on structual surfaces while allowing stratification in the sump; and novel baffle means are provided to cause a controlled air blowback across the sump to facilitate collection of the floating material therein.

Gas scrubbing apparatus

This invention relates to a spacer-turbulator for use in separating corrugated type fill sheets of a cross-flow cooling tower and for imparting turbulence to the air flowing through said fill in said cross flow cooling tower.

Spacer-turbulator

An injector type spray cooling system is described having a cooled water recovery sump in which water is directed through a strainer slanted with its upper edge upstream so that a self cleaning action is produced.
