摘要:
Low cost sealing drainboard supports adapted for use between adjacent drift eliminator sections in water cooling towers are provided which can be readily installed in the field without the necessity of custom fabrication of structural components, and which give improved drainage characteristics in the form of relatively large, concentrated streams of eliminated water resistant to reentrainment. The preferred supports are unitary, preformed synthetic resin bodies presenting an elongated, eliminator section-receiving channel together with a depending inner sealing wall and a oblique, downwardly and outwardly extending drainage tray. The tray is preformed to present a series of generally V-shaped in plane, increasing depth drainage passageways serving to collect and concentrate eliminated water into relatively large streams resistant to reentrainment in the air currents passing through the tower.

A splash bar for use in fill structure of an evaporative cooling tower has an extruded body with an elongated water impingement portion operable to uniformly disperse deflected water throughout the fill structure for contact with passing air. The splash bar body comprises a pair of arcuate in cross section side margins and an elongated, horizontal, flat top segment interconnecting the side margins. The centers of curvature of the side margins are coincident and lie beneath the body, while the width of the flat top segment is in the range of approximately 15% to approximately 35% of the overall width of the body. In preferred forms of the invention, the width of the flat top segment is approximately 25% of the overall width of the body. Advantageously, the body is hollow and includes a pair of spaced, flat, co-planar bottom walls integrally extending inwardly from the side margins. In alternate forms of the invention, the splash bar includes a pair of outwardly extending elongated side flanges coupled to the body and having notches adapted for clearing upright grid members, in order to substantially preclude longitudinal shifting of the bar as a result of vibration from the tower during operation.

摘要:
A heating tower apparatus for heating a liquid having an air flow inlet stream and a first air flow outlet and a second air flow outlet. The first air flow outlet provides a first outlet air flow stream and has a first outlet door that moves between an open position and a closed position. The second air flow outlet provides a second outlet air flow stream and has a second outlet door that moves between an open position and a closed position. The heating tower also includes a heat exchange portion having coils through which liquid to be heated flows. The heating tower is operable in a first configuration wherein the first outlet door is in the open position while the second outlet door is in the closed position. The heating is also operable in a second configuration wherein the second outlet door is in the open position while the first outlet door is in the closed position.
摘要:
A heating tower apparatus for heating a liquid having more than one inlet and more than one outlet. Each of the more than one inlet and more than one outlet is selectively openable and closable. The heating tower apparatus also includes a liquid distribution assembly and a fill medium. The liquid distribution assembly distributes the liquid onto the fill medium.

A dual path drift eliminator and method is provided which effectively removes entrained water particles from high velocity moist airstreams leaving a crossflow cooling tower fill structure by the use of spaced, cellular, individually draining, diversion path-defining structures strategically located and arranged to facilitate maximum drift elimination. The drift eliminator has a plurality of elongated air passages therein disposed to first divide the moist air from the tower fill into a series of separate streams which are first diverted at an upward angle relative to the initial path thereof, and thereafter rediverted laterally to one side of the first diversion path. Water particle removal is thus greatly enhanced by virtue of increased impingement of the entrained particles against the cellular walls defining the respective diversion paths. The eliminators hereof have special advantages in crossflow cooling towers because the spacing between the diversion path defining cellular structures permits separate draining of the water collected in each, so that air inlet blockage resulting from the accumulated drainage of large volumes of water from a single drainage area is avoided. The eliminator structure preferably includes a number of juxtaposed pairs of spaced, elongated, transversely corrugated, preformed sections sandwiched between elongated, preformed, transversely V-shaped panels to define a structurally distinct eliminator pack which can be manufactured using assembly line techniques; such packs are moreover of nestable configuration permitting complemental positioning of a plurality of packs to present a substantially continuous drift eliminator unit free of objectionable vertical gaps, notwithstanding the lack of conventional shiplap joints or other mechanical interconnection between individual eliminator packs.

A fill pack assembly and method for assembling a fill pack from individual sheets utilizes integrally bonded sheet pairs. Each sheet pair is a pair of two individual adjacent fill sheets which have been bonded together via any suitable bonding method. A plurality of the thus formed sheet pairs can then be attached together to form an entire fill pack or portion of a fill pack. Such fill packs are useful in heat exchange devices such as industrial cooling towers.

A cross-flow cooling tower having a frame assembly that is unitarily molded from a plastic material. The frame assembly has opposing top and bottom walls along with opposing side walls and opposing ends. The side walls extend parallel to one another between the top and bottom walls. In addition, the opposing ends extend parallel to one another between the top and bottom walls. The frame assembly additionally has a vertical stack extending vertically from the top wall. The top covers of the tower extend outwardly and downwardly from the vertical stack.
