Abstract

The invention relates to a waste sizing water recovery system, which is characterized in that a circulating pump (6) and a valve are installed in a sizing machine (1). Circulating pumps (6) and valves are also installed on a size pipe (8), a size return pipe (9) and a water return pipe (10). The sizing machine (1) is connected with the tops of a size return kettle (4) and a plurality of size mixing kettles (3). Two pressure size boiling kettles (2) and the bottoms of the size mixing kettles (3) are connected with the sizing machine (1) through the size pipe (8). The bottom of a floor water containing device (7) is connected with the top of a water return kettle (5) through the water return pipe (10). The bottom of the water turn kettle (5) is connected with the top of the size return kettle (4) through the water return pipe (10). The bottom of the size return kettle (4) is connected with the size return pipe (9) through the water return pipe (10). The waste sizing water recovery system can recover and utilize usable size and washing water in waste sizing water.

Description

technical field [0001] The invention relates to waste sizing water recycling, in particular to a waste sizing water recycling system in the textile industry. Background technique [0002] According to statistics, the pollution caused by desizing in printing and dyeing wastewater accounts for a considerable proportion, accounting for about 50% of textile wet processing and finishing wastewater. A large number of pollutants in desizing wastewater come from the size used in the sizing process. At present, most of the pulp used in textile mills is a mixed pulp composed of natural pulp and chemical pulp. In chemical pulp, polyvinyl alcohol (PVA) has good film strength, flexibility, and wear resistance. It has been widely used in the process of warp yarn sizing due to its advantages of non-toxicity, adhesion and chemical stability. [0003] As a kind of size with excellent performance, the application of PVA solves many problems in sizing. However, due to its long biodegradation...
