Abstract

The invention discloses a drying process of sulfonate. The drying process of the sulfonate comprises the following steps: (1) uniformly distributing paste sulfonate with an active matter in a concentration of 37-65% and water in a content of 63-35% on a conveying belt to enter a microwave dryer and obtain sulfonate with water in a content of 5-10% in a microwave drying stage; (2) feeding the sulfonate with water in the content of 5-10% into a hot air dryer to obtain sulfonate with water in a content of less than or equal to 1% in a hot air drying stage; and (3) obtaining slice sulfonate with the water in the content of less than or equal to 1% in a cold air cooling state. Water molecules in a material vibrate with a high frequency directionally and rub against each other, so that the overall material forms a radiation body; microwave directly acts on the water molecules, so that conduction loss is avoided, the drying time is short and only lasts for several minutes or dozens of minutes; the microwave directly acts on the water molecules, so that temperature is easily controlled; the microwave transmits and heats selectively; the drying is uniform; quality of the material can be improved; and energy utilization rate is high.

Description

technical field [0001] The invention relates to a drying process for preparing high-purity sulfonate. Background technique [0002] The sulfonate drying process mainly adopts the following types of dryers: drum scraper dryer, spray dryer, vacuum rake dryer and microwave dryer. [0003] 1) Drum scraper dryer: The working principle of the drum dryer is to let the liquid or muddy material form a thin film on the surface of the drum heated by steam or other heat carriers, and the drum will be dried in the process of one revolution. The product is scraped off, and the exposed drum surface is in contact with the material again and forms a film for drying. The crushing and packaging of dry materials need to be carried out in a dehumidified closed space. When used for sulfonate products, this drying method has the following problems: First, the material is still at high temperature after drying, and will not become brittle and completely detached from the surface of the drum, but ...
