Embodiment Construction

[0008] The device mainly includes two main parts of humidification and discharge. The humidification chamber 1 is equipped with a water inlet pipeline, and the material enters from the feed port 3. Driven by the horizontal motor unit, it first passes through the humidification chamber to rotate and humidify, and then enters the discharge chamber 4, and automatically falls into the conical disk under the action of gravity. 5, the conical disc body is driven by the longitudinal motor unit 7, and there are also holes for cloth on the conical disc body. Under the joint action of gravity and centrifugal force, the material is evenly dispersed when falling to achieve uniform cloth distribution. The speed of the conical disc turntable can be 5-3000 rpm, and the feeding amount is determined according to different speeds.

Abstract

A moistening-distributing apparatus for the lime powder used in dry desulfurizing equipment is composed of moistening cabin, water inlet tube, material feeding port, material discharging cabin, conic disk, tronsverse electric motor set and longitudinal electric motor set. Its advantages are low height, high moistening effect and distributing uniformity, and no raise dust.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and relates to a humidifying and distributing device that needs to use lime and other fine powder materials in a dense-phase dry desulfurization reactor. Background technique [0002] It is very common to use fine powder materials in the desulfurization process, and the phenomenon of dust pollution in the feeding process is relatively serious, especially in the application process of quicklime not only produces dust pollution, but also produces steam pollution due to the heat release of quicklime when distributing water. It is almost necessary to use quicklime as a desulfurizer in the flue gas desulfurization process, and the reverse drying tower of the flue gas desulfurization island is an essential equipment. The commonly used feeding equipment does not have a humidification function, and the dust pollution caused by the cloth distribution process is particularly serious. Contents of th...
