Problems solved by technology

Especially when the outside temperature is low, condensed water will form in the pipeline and the inner wall of the centrifugal fan, which will cause the centrifugal fan to corrode and rust.
The current improvement method is to apply a layer of anti-corrosion and waterproof coating on the inner wall of the centrifugal fan casing and the surface of the impeller, which has improved to a certain extent. The risk of components being corroded remains high

Abstract

The invention discloses a centrifugal fan for a wet devulcanizer. The centrifugal fan comprises an impeller; a motor is connected to the center of the impeller through a bearing; a first outer shell is arranged at the external of the impeller; an upper port position of the first outer shell is welded with an upper port of a second outer shell through a connecting rod; the two sides of the second outer shell are connected with brackets; the brackets are connected to a base; a liquid storage tank is formed in the bottom of the second outer shell; and a detachable sealing piece is arranged at thelower end of the liquid storage tank. The centrifugal fan for the wet devulcanizer is simple in structure and convenient to use, can improve the corrosion resistance to prolong the service life, andcan return condensed alkali liquid into a devulcanizing tower to reduce waste of the alkali liquid.

Description

technical field [0001] The invention relates to the technical field of a centrifugal fan, in particular to a centrifugal fan used in a wet desulfurizer. Background technique [0002] In the prior art, the marine desulfurizer uses lye to wash the flue gas containing sulfur dioxide to chemically absorb the sulfur dioxide in the flue gas. In order to strengthen the absorption process and improve the desulfurization efficiency, a centrifugal fan is used to make the flue gas rotate and flow to the inside of the desulfurization tower at a high speed, meet and contact with the atomized water vapor sprayed from the atomizer, and fully mix the sulfur dioxide in the flue gas to dissolve in the water mist In the process, the water condensed by dust and dust particles and water mist is thrown to form a water film under the action of centrifugal force, and flows down the inner wall. Most of it is discharged from the drain, and a small part flows into the centrifugal fan through the inner...
