Raw material waste heat heating device for whitening agent

Abstract

The raw material waste heat heating device comprises a raw material box, the raw material box is sleeved with a heat supply pipe extending into the raw material box, the left end of the heat supply pipe is communicated with an adjusting mechanism erected outside the left side of the raw material box through a connecting pipe, the right end of the heat supply pipe is connected with a backflow pipe, and a heat inlet pipe is fixed to the left side of the adjusting mechanism through a bolt; and communicating pipes which are communicated with each other are also welded between the heat inlet pipe and the return pipe, and electromagnetic air valves are mounted on the communicating pipes. Preheat of other equipment is input into the adjusting mechanism through the heat inlet pipe, the temperature is adjusted to meet the heating temperature of raw materials, heat is dissipated into the raw material box from the heat supply pipe so that heating can be conducted, low-temperature air on the bottom layer in the heated raw material box flows away from the backflow pipe, and therefore it is guaranteed that the heating temperature of the raw material box is balanced. The raw material waste heat heating device for the whitening agent is ingenious in structural arrangement, reasonable in layout, easy to operate, convenient to use and good in effect.

Description

technical field [0001] The invention relates to the technical field of whitening agent production equipment, in particular to a waste heat heating device for whitening agent raw materials. Background technique [0002] Brightener is a fluorescent dye, or white dye, and it is also a complex organic compound that can improve the whiteness of fiber fabrics and paper. Its characteristic is that it can stimulate the incident light to produce fluorescence, so that the dyed substance can obtain a sparkling effect similar to fluorite, and make the substance very white to the naked eye. It is also called optical brightener and fluorescent whitening agent. Fabrics, etc. are often yellow due to colored impurities. In the past, chemical bleaching was used for decolorization. Now, the method of adding brighteners to products is used. [0003] At present, in the production process of whitening agents, heat is used in many links, and the heat will be lost invisibly during the heating proc...

AI Technical Summary

Problems solved by technology

[0003] At present, in the production process of whitening agents, heat is used in many links, and these heats will be lost invisibly during the heating process, and the raw materials of whitening agents are generally heated and preheated during production. Warm equipment increases the cost of equipment, which is not conducive to energy saving
