Sulfur dioxide cooler

Abstract

The invention discloses a sulfur dioxide cooler which comprises a cooling case, a plurality of heat exchange tubes are uniformly arranged and mounted in a case cavity of the cooling case in a vertically fixed state, four guide sliding sleeves are fixedly connected together through a supporting platform frame, and the plurality of heat exchange tubes penetrate through a plurality of through insertion holes in a one-to-one correspondence manner; a circle of bristles are densely installed on the inner wall face of the brush base, the bristles are tightly attached to the pipe wall of the heat exchange pipe, the guide sliding sleeve located on the right side of the front portion is further fixedly connected with an internal thread sleeve, and the internal thread sleeve is installed on a power screw in a matched mode in a matched mode through a thread screw. Left-end wheel edge teeth of the left half bevel gear and left-end wheel edge teeth of the right half bevel gear are matched with the full-tooth bevel gear in a transmission mode. The problem that impurities are easily attached to the pipe wall in the prior art is solved, and the heat exchange efficiency of the heat exchange pipe is improved.

Description

technical field [0001] The invention relates to the related technical field of sulfur dioxide gas processing equipment, in particular to a sulfur dioxide cooler. Background technique [0002] Sugarcane sugar production burns sulfur in a sulfur furnace to generate sulfur dioxide. After cooling, the sulfur dioxide is used to adjust the pH value of sugar juice and syrup on the one hand, and on the other hand to react with milk of lime to form calcium sulfite, which is used to remove color by adsorption of calcium sulfite. Matter and non-sugar, improve the purity of sugar juice and syrup, reduce the color value of sugar juice and syrup. This process is called sulfur fumigation in sugar technical terms. Sulfur fumigation is a key process control point in the sugar making process, and the effect of sulfur fumigation directly affects product quality and sugar recovery. Sulfur burning furnace is divided into low temperature sulfur burning furnace and high temperature sulfur burnin...

Problems solved by technology

[0005] Although this processing device of prior art can cool sulfur dioxide, there is a serious defect, that will produce a small amount of residue with light quality in the working process, and these small amount of residue will be directly attached to the tube wall of heat exchange tube 105 On the surface, if it lasts for a long time and slowly accumulates, it will easily lead to thickening of the tube wall, which will affect the heat exchange efficiency of the heat exchange tube 105 and reduce the cooling effect of sulfur dioxide. The device that the pipe wall of pipe 105 is cleaned is particularly important
