Filed:

Sep 7, 2007

Appl. No.:

11/851443

Inventors:

Norman D Nelson - Akron OH, US
George D. Burges - Mentor OH, US

International Classification:

B01D 50/00

US Classification:

422177

Abstract:

The present invention generally relates to devices for diverting contaminants into catalyst blocks; and in particular to devices for diverting particulate matter such as powdered and/or solid contaminants away from spaces around and between catalyst blocks.

International Classification:

B01F 304

US Classification:

261116

Abstract:

A method and apparatus for supporting headers within a tower from adjacent headers thereby reducing the amount of support members needed. In this configuration, the headers, which extend from opposing sides of the tower, are interspaced within the same generally horizontal plane in the tower. Support for the cantilevered end of each header is supplied by the self-supporting capabilities of adjacent headers near their support point with the tower wall. This significantly reduces the loaded span of support members to the distance between such adjacent headers as well as reduces the load upon such support member.

International Classification:

B01D 4706
B01D 4710
B01D 4714

US Classification:

96297

Abstract:

An improvement in a center inlet type scrubber that retrofit the scrubber with a perforated tray made up of rectangular or partially rectangular sections supported on beam supports in the annulus of the scrubber. The supports can be modified to form turning vanes or additional turning vanes can be employed. One or more perforated trays may be installed in the annulus to help correct the problem.

Abstract:

An overhead catalyst loading device eliminates the need for lower flanges of the overhead catalyst structural support frame or dedicated overhead trolley beams to prevent ash build up collecting on a selective catalytic reactor (SCR) reactor box and provides an advantageous electric hydraulic lifting mechanism suitable for integration into a SCR device. The overall width of the SCR device is reduced since the structural support frame in the SCR device fits in the gaps between catalyst blocks. The overhead electric hydraulic catalyst loading device also minimizes the chance of injury during catalyst block installation by using an electric hydraulic actuated lifting mechanism consisting of spacers and structural telescopic members which may comprise holes and pins for height adjustment to allow for loading and unloading catalyst blocks into and out of a SCR device. Methods of lifting and loading and unloading a catalyst block are also presented therein.
