Adjustable PP centrifugal fan for waste gas treatment washing tower

Abstract

The invention discloses an adjustable PP centrifugal fan for a waste gas treatment washing tower, which comprises a base, a height adjusting mechanism, a bottom plate, a gear plate, a fan bracket and a PP centrifugal fan, the base is groove-shaped, the height adjusting mechanism is arranged in the base, the bottom plate is arranged on the height adjusting mechanism, the gear plate is rotatably arranged on the bottom plate, the fan bracket is fixedly arranged on the gear plate, and the PP centrifugal fan is arranged in the base. The PP centrifugal fan is rotatably arranged on the fan bracket, and a group of fan tooth blocks are arranged on the outer side of the PP centrifugal fan; the direction adjusting mechanism drives the gear plate to rotate, and the angle adjusting mechanism drives the fan tooth block to rotate. According to the adjustable PP centrifugal fan for the waste gas treatment washing tower, the height of the PP centrifugal fan is adjusted through the height adjusting mechanism, the horizontal direction of the fan is adjusted through the direction adjusting mechanism, and the included angle between the fan and the horizontal plane is adjusted through the angle adjusting mechanism; the position and the direction of the air port of the PP centrifugal fan for the waste gas treatment washing tower are convenient to adjust.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to an adjustable PP centrifugal fan for waste gas treatment scrubbers. Background technique [0002] The washing tower is a new type of gas purification treatment equipment. It is improved on the basis of the floating packing layer gas purifier. It is widely used in the pretreatment of industrial waste gas purification and dust removal. The purification effect is very good. For the coal gasification process, coal gas washing is inevitable. No matter what coal gasification technology uses this unit operation, because its working principle is similar to the washing process, it is called a scrubber. Industrial waste gas usually contains soot and productive dust. In the scrubber A filter link is installed in the middle to remove dust. The centrifugal fan is an essential part of the washing tower, relying on the mechanical energy input by the centr...

AI Technical Summary

Problems solved by technology

Existing PP centrifugal fans are usually integrally formed with the base or installed on the base by bolts. The position and direction of the tuyere are fixed. When it is necessary to adjust the blowing direction of the PP centrifugal fan, the PP centrifugal fan needs to be removed and reinstalled or installed to other components. On the other hand, the installation process is cumbersome and time-consuming
