An apparatus for inserting a venturi tube having an inlet, an aspirator inlet and an outlet directly within a fluid flow stream, with the aspirator inlet not in contact with the fluid flow stream is disclosed. A plate having a first aperture leading to the venturi inlet, and a series of second apertures both supports the venturi within a conduit and divides the fluid flow stream into a first stream which flows through the venturi tube and a second stream which flows around the venturi tube. A variety of adjusting mechanisms are disclosed for varying the cross sectional area of the second apertures relative to the cross sectional area of the venturi tube. The apparatus is adapted to allow the back pressure within the venturi tube (which increases as the fluid flow rate increases) to force an increasing proportion of the flow stream to flow around the venturi tube in order to maintain a relatively constant aspiration rate within the venturi tube. The adjustment mechanisms disclosed include a second plate, similar to the first plate, which is manually rotated and a blocking ring which moves responsive to changes in rate of flow of the fluid flow stream.

In-line venturi

A cooler for use with gaseous process fluids such as air containing a vapor has a vapor adsorption unit for passing process air through an adsorption media to dry the air, a heat exchanger to control the temperature of the heat adsorption media and process air, a vapor removal system for removing the adsorbed vapor from the adsorption media, and a humidification unit to add a vaporizable liquid to the dried process air, so as to vaporize the liquid into the dried process air. Thus, heat in the process air is utilized for the latent heat of vaporization of the liquid to reduce the temperature in such process air, while maintaining a predetermined humidity level in said air. The vaporizable liquid may be sprayed into the process fluid as a mist. Excess cooled coalesced liquid may be used in a heat exchanger to precool the process fluid before it enters the humidifier. The invention includes a method of chilling a gaseous fluid, by means of adsorption of vapor from such fluid while controlling the temperature thereof, and subsequently adding a vaporizable liquid to such dried fluid whereby to vaporize such liquid and thus cool the fluid.
