Collection and utilization system for waste alkaline water

Abstract

The invention provides a collection and utilization system for waste alkaline water. The collection and utilization system comprises a fresh alkaline pool and an alkaline liquor recycle pool. A leading-in pipe is arranged at the lower end of the fresh alkaline pool, and alkaline liquor in the fresh alkaline pool enters the alkaline liquor recycle pool through the leading-in pipe. A filtering net is arranged in the alkaline liquor recycle pool and is of a planar net structure, the bottom of the alkaline liquor recycle pool is connected with a leading-out pipe, and the other end of the leading-out pipe is connected with a boiling-off machine and a dyeing machine. The alkaline liquor recycle pool is a cylinder, an upward shaft perpendicular to the filtering net is arranged in the center of the upper surface of the alkaline liquor recycle pool, one end of a scraper blade is connected with the shaft, the scraper blade can rotate around the shaft by any angle, and the length of the scraper blade is slightly smaller than the radius of the alkaline liquor recycle pool. By applying the collection and utilization system for the waste alkaline water, the collected waste alkaline water can be conveyed to the boiling-off machine and the dyeing machine and then used again, and therefore the utilization rate of the waste alkaline water is improved. Meanwhile, impurities in the waste alkaline water can be eliminated, so that the clear alkaline liquor is recycled, and subsequent process operation can not be influenced.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing equipment, and in particular relates to a system for collecting and utilizing waste alkali water in a light alkali pool of a mercerizing machine. Background technique [0002] With the increase of fabric functional finishing methods, people have higher and higher requirements for the health and environmental protection of fabrics, and higher and higher requirements for corporate social responsibility. Enterprises are increasingly restricted by energy shortages such as water, electricity, and steam, and environmental protection pressure. Because the existing mercerizing machine is not equipped with a waste alkali water collection and utilization system, the waste alkali water of the mercerizing machine is discharged into the water for treatment. Because of the large amount of water, the cost of sewage treatment and sewage discharge is high, which greatly increases the cost of se...

Problems solved by technology

Because the existing mercerizing machine is not equipped with a waste alkali water collection and utilization system, the waste alkali water of the mercerizing machine is discharged into the water for treatment. Because of the large amount of water, the cost of sewage treatment and sewage discharge is high, which greatly increases the cost of sewage treatment and restricts the enterprise. develop
