Variable fog drop diameter atomization disc

Abstract

The invention discloses a variable fog drop diameter atomization disc. An upper shell, a lower shell, a rotation shaft and a pressing nut are included. The upper shell and the lower shell are fixedlyconnected, the pressing nut sleeves the rotation shaft, and three layers of through holes are arranged in the side wall of the upper shell from top to bottom, wherein the through holes are different in diameter and are used for arranging nozzles or plugs. One nozzle and one plug are alternately arranged in the first layer of through holes, one nozzle and one plug are alternately arranged in the second layer of through holes, two nozzles and two plugs are alternately arranged in the third layer of through holes, and each nozzle of the first layer and the corresponding plug of the second layer are located in one row. The atomization disc further comprises a middle baffle, the middle baffle comprises a hollow cylindrical baffle body, an annular baffle base and a baffle connecting rod, the baffle body is provided with holes corresponding to the through holes, and the baffle base is fixed to the upper portion of the pressing nut. By means of the atomization disc, the fog drop reaching rangeand the fog drop diameter can flexibly change, adaptive treatment of different smoke concentration work conditions can be achieved, a good smoke treatment effect is achieved, and energy and cost aresaved.

Description

technical field [0001] The invention relates to the technical field of waste incineration flue gas purification equipment, in particular to an atomizing disc with variable droplet diameter. Background technique [0002] The flue gas after garbage incineration is usually purified by a flue gas purification device to remove the acid gas in the flue gas, so that the flue gas can meet the emission standards without causing secondary environmental pollution. The core component of the semi-dry flue gas deacidification purification device is the rotary atomizer. The rotary atomizer is driven by a motor. Through the intermediate transmission device, the atomization disc of the atomizer is driven to rotate at high speed, and the high-speed rotating atomization disc generates powerful The centrifugal force, the material in the form of suspension or emulsion (eg, lime slurry) is sprayed through the nozzle of the atomizing disc, and thus atomized into droplets with a micron size (eg, 50...

AI Technical Summary

Problems solved by technology

In the prior art, in order to achieve a better flue gas treatment effect, it is generally used to increase the speed of the drive motor or increase the liquid intake of the lime slurry, which will cause unnecessary waste of energy or raw materials
