Type 7010 Ejector-Venturi Scrubber

The Type 7010 scrubber is the key component in the S&K ejector-venturi system. These highly engineered scrubbers operate on the ejector-venturi principle illustrated on page 2. The Type 7010 is used in many applications to provide efficiencies as high as 99% or more in a single stage system (higher efficiencies can be obtained through use of multi-stage configurations). Gas handling capacities of over 90,000 CFM are possible with the larger size scrubbers (refer to Technical Supplement 7S for capacity data).

Installation, operation and maintenance are greatly simplified with these scrubbers. They can be mounted on an existing discharge or storage tank or provided with a Schutte & Koerting gas/liquid separator as shown below.

To answer the need for an economical, versatile and efficient pollution control device, S&K offers standard Type 7010 scrubbers in a variety of sizes and materials. Stock 7010 scrubbers are available for immediate shipment in sizes from 3" to 12" in materials which include carbon steel, stainless steel, polyvinyl chloride (PVC), HAVEG, fiberglass­reinforced plastic (FRP) and cast iron. A minimum of three spray nozzle sizes are available with the stock scrubbers and can be selected to properly match the motive liquid used and capacity required.

The Type 7040 separator is designed for use with the 7010 scrubber to maximize gas/liquid separation after the mixture is discharged from the scrubber. The Type 7040 reduces moisture carryover from the scrubber to as low as 0.0002 gallons per 100 cubic foot which, in turn, contributes to overall scrubber efficiency. The separator consists of an inlet at the top, a drain at the bottom and a clean gas outlet at the side of the separator. A separating element, which incorporates a unique baffling arrangement, is located just below the inlet. Scrubbing liquid from the separator can be drained to a storage tank or recirculated through the system.

Stock Type 7040 separators are available in sizes from 3" to 12" in fabricated steel, stainless steel, and FRP for use with stock Type 7010 scrubbers of the same size.

The Type 7014 scrubber-separator is a complete, single stage scrubbing system combining a Type 7010 ejector­venturi scrubber and a Type 7040 separator. This system utilizes the ejector-venturi principle to entrain and scrub large volumes of gas containing fumes, vapors, noxious gases, dusts, odors or particulates, and vent clean, dry gas to the atmosphere. The Type 7014 system is capable of providing efficiencies as high as 99% or more in a single stage system and higher in a multi-stage configuration. Gas handling capacities range from 25 CFM for a 3" scrubber to over 2000 CFM for a 12" scrubber.

The compactness and design simplicity of the Type 7014 scrubber system permits installation in difficult to reach areas.

Schutte & Koerting has made both economy and efficiency possible in a pollution control system by offering stock Type 7014 systems in a variety of materials and sizes. Scrubbers from 3" to 12" are available in carbon steel, stainless steel, and FRR.

Virtually every type of contaminant including particulates, fumes, noxious gases, odors and vapors are encountered in the chemical plant. Here is where the Schutte & Koerting ejector-venturi scrubber finds its broadest use due to its removal efficiencies over the entire range of pollutants. Acid mists, amine fogs, furfural dusts and odors from organic wastes have all been removed from gas streams with 98% plus efficiencies using ejector-venturi scrubbers.
