Problems solved by technology

The second is that a large number of used clothes are mostly buried or burned as garbage, which not only causes a waste of resources, but also pollutes the environment
This method requires less investment and simple technology, but the quality of the regenerated fiber obtained is poor, and the profit of the enterprise is low, which greatly limits the recycling value and economic value of recycling waste clothes.

Embodiment 1

[0022] Pretreatment: Add 2% sodium hydroxide solution to the collected waste clothes, ultrasonically clean them in water at 20 degrees Celsius for 2 hours, wash with water to remove dirt and dirt on the clothes, then dry and chop them to remove zippers, buttons and others appendage;

[0023] Acidification: the pretreated cotton cloth head is mixed and contacted with a hydrochloric acid solution with a mass fraction of 9%, the contact temperature is 25 degrees Celsius, and the contact time is 12 hours to obtain an acidified cotton cloth head;

[0024] Hydrolysis and saccharification: in the presence of water, under the condition of solution temperature of 85 degrees Celsius, the acidified cotton cloth head is contacted with an oxidizing agent for 7 days;

[0025] Filtration: Use a filter to filter the solids in the solution, and the obtained solution is a hydrolyzed glucose solution;

[0026] Neutralization: adjust the pH value of the glucose solution to be neutral with sodium...

Embodiment 2

[0029] Pretreatment: Add 8% sodium hydroxide solution to the collected waste clothes, ultrasonically clean them in water at 40 degrees Celsius for 3 hours, wash with water to remove dirt and dirt on the clothes, then dry and chop them to remove zippers, buttons and others appendage;

[0030] Acidification: the pretreated cotton cloth head is mixed and contacted with a hydrochloric acid solution with a mass fraction of 10%, the contact temperature is 35 degrees Celsius, and the contact time is 24 hours to obtain an acidified cotton cloth head;

[0031] Hydrolysis and saccharification: in the presence of water, under the condition of solution temperature of 95 degrees Celsius, the acidified cotton cloth head is contacted with an oxidizing agent for 12 days;

[0032] Filtration: Use a filter to filter the solids in the solution, and the obtained solution is a hydrolyzed glucose solution;

[0033] Neutralization: adjust the pH value of the glucose solution to be neutral with sodi...

Embodiment 3

[0036] Pretreatment: Add 6% sodium hydroxide solution to the collected waste clothes, ultrasonically clean them in water at 35 degrees Celsius for 3 hours, wash with water to remove dirt and dirt on the clothes, then dry and chop them to remove zippers, buttons and others appendage;

[0037] Acidification: the pretreated cotton cloth head is mixed and contacted with a hydrochloric acid solution with a mass fraction of 9.5%, the contact temperature is 30 degrees Celsius, and the contact time is 24 hours to obtain an acidified cotton cloth head;

[0038] Hydrolysis and saccharification: in the presence of water, under the condition of solution temperature of 95 degrees Celsius, the acidified cotton cloth head is contacted with an oxidizing agent for 10 days;

[0039] Filtration: Use a filter to filter the solids in the solution, and the obtained solution is a hydrolyzed glucose solution;

Abstract

The invention discloses a method for making fuels by utilizing fermentation of waste cotton clothes, and belongs to the technical field of resource regeneration. The method comprises six steps of pretreatment, acidification, hydrolysis and saccharification, filtration, neutralization and fermentation. The used raw materials are waste cotton clothes, so that the handling problem of the waste cotton clothes is solved, and the produced alcohol serving as a cleaning fuel has an extremely high application value and an economic benefit in the resource-poor and energy-scarcity modern society.

Description

technical field [0001] The invention belongs to the technical field of resource regeneration, in particular to a method for using waste cotton clothes as fuel through fermentation. Background technique [0002] The scarcity and pollution of resources are common problems faced by the world today. The textile industry is closely related to people's lives, and the world's textile industry is also facing two major problems: First, with the development of the world economy and technology, the application field of textiles is gradually expanding, but its service life is shortened. With the rapid growth, the consumption of textiles has increased greatly, resulting in a shortage of textile raw materials and a sharp rise in prices. The second is that a large number of used old clothes are mostly buried or burned as garbage, which not only causes a waste of resources, but also pollutes the environment. The completion of a piece of clothing involves a complex industrial chain and a l...
