Abstract

The invention discloses a device for improving the dehydrating efficiency of a vacuum belt dehydrator and a mounting method. The device is erected on the vacuum belt dehydrator, and comprises brackets, a rotary shaft, first guide wheels, second guide wheels and roller lines. The brackets, the first guide wheels and the second guide wheels are symmetrically arranged on the rotary shaft. The brackets are symmetrically arranged on the two sides of the vacuum belt dehydrator, and U-shaped grooves are formed in the upper portions of the brackets. The rotary shaft is arranged on the brackets, the two ends of the rotary shaft are arranged in the U-shaped grooves of the brackets on the two sides respectively, the first guide wheels and the second guide wheels are circular truncated cones and are arranged on the rotary shaft, the outer bottom faces of the second guide wheels are attached to the inner bottom faces of the first guide wheels, and the inner bottom faces of the second guide wheels are attached to third steps. The roller lines are tensioned and wound around the outer edges of the second guide wheels to be fixed to the second guide wheels. Hardened materials on a belt conveyor arebroken and spread, the materials continue to be dehydrated, the dehydrating effect of the vacuum belt dehydrator is improved, the dehydrating efficiency is improved, and the device is low in manufacturing cost and convenient to detach and mount.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization auxiliary devices, in particular to a device and an installation method for improving the dehydration efficiency of a vacuum belt dehydrator. Background technique [0002] At present, the most widely used desulfurization method for flue gas desulfurization in domestic thermal power plants is limestone-gypsum wet flue gas desulfurization technology. The main process is: absorb sulfur dioxide in flue gas with limestone slurry, and oxidize calcium sulfite The desulfurization by-product calcium sulfate is then removed by vacuum belt dehydrator to desulfurization gypsum with a water content of less than 10%, which can be used commercially. It will harden on the belt to form a hardened material layer, which will affect the normal operation of the desulfurization device. In the wet desulfurization system, the poor dehydration effect of the vacuum belt is a major technical difficulty in ...
