Problems solved by technology

In this production process, due to the high temperature, the extracted components after the solvent evaporates are concentrated into soot residues, and the production equipment such as extraction equipment, pipelines for conveying the extraction liquid, and applicators are often blocked, and they must be cleaned almost every day, otherwise they will not work normally. delivery and production
This is a new type of industry. Cleaning with dozens of cleaning agents currently available on the market cannot effectively remove the smoke and dirt. The cleaning time is long and the cost is high.
There is currently no specific cleaning agent

Abstract

The invention provides a soot cleaning agent, which is prepared by mixing a surfactant, mineral acid, a solvent and distilled water. The surfactant is secondary alkanol polyethenoxy ether and nonyl phenol polyethenoxy ether. The mineral acid is prepared with nitric acid with the concentration of 70 percent, vitriol with the concentration of 98 percent, and phosphoric acid with the concentration of 85 percent. The solvent is ethylene glycol monobutyl ether or ethylene glycol monomethyl ether. The soot cleaning agent provided by the invention is used exclusively in cleaning the soot inside tobacco manufacturing equipment and delivery conduits, and can completely clean the soot of production equipment pipes quickly at low cost.

Description

technical field [0001] The present invention relates to soot cleaning agent. More specifically, it refers to the equipment used in the production process of tobacco leaves and tobacco stems to be reprocessed into high-grade cigarettes and the removal of soot in the pipeline. Background technique [0002] Tobacco leaf powder, tobacco stems, and tobacco stems were treated as garbage in the past, and now they are subjected to a certain extraction process in a solvent, enzyme, and water medium to obtain a thick extract (dark brown mucus, mainly nicotine, alkaloids) , the residue is rich in cellulose to make special paper, the paper is coated with this extract and dried to make cigarette paper, and then shredded, it can be made into high-grade cigarettes that basically do not contain harmful substances such as tar, waste Utilization is a new type of industry with great social and economic benefits. In this production process, due to the high temperature, the extracted component...
