Pretreatment rinsing system for textile printing and dyeing industry

Abstract

The invention discloses a pretreatment rinsing system for textile printing and dyeing industry, and belongs to the technical field of textile fabric production. The system comprises a water washing box and a water washing, filtering and deoiling device which are connected with each other, wherein the water washing box comprises a water washing tension roller, a first water washing cloth guide roller, a first water washing access cover, a scouring illuminating lamp, a water washing spraying pipe, a first water washing separator roller, a second water washing cloth guide roller, a second water washing separator roller, a second water washing access cover, an upper water washing roller, a lower water washing roller, a water washing tank, a first water washing rubber roller, a third water washing separator roller, a fourth water washing separator roller, a water washing circulating pump, a water washing combustor heat exchange pipe, a first spray roller, a second spray roller, a water washing roller, a fifth water washing separator roller, a sixth water washing separator roller, a second water washing rubber roller and a water washing box body. The system tension is zero, the water washing efficiency is high, and energy and water are saved; and the whiteness, the capillary effect, the water washing fastness and the rubbing fastness of fabric are improved, and the colored light andthe hand feeling of dyed and shaped fabric are improved.

Description

technical field [0001] The invention relates to a pretreatment and rinsing system in the textile printing and dyeing industry, belonging to the technical field of textile fabric production. Background technique [0002] In the process of textile printing and dyeing, the main ecological problems currently faced are water saving, energy saving and reduction of sewage discharge. The pre-treatment of textile printing and dyeing consumes a lot of water and sewage discharge, which not only increases the cost due to rising water prices, but is even more serious What is worse is that all countries in the world, including my country, have insufficient water resources, and at the same time, the discharge standards after sewage treatment are becoming more and more stringent. [0003] Due to the lack of water resources in our country, the utilization rate is relatively low and the distribution is not uniform enough, and people's demand for water resources is constantly increasing, so it ...

AI Technical Summary

Problems solved by technology

At present, in my country's textile printing and dyeing, the energy consumption is about 3 tons of coal per 10,000 meters of cloth, 450 degrees of electricity consumption, and 300-400 tons of water consumption. The energy consumption is 3-5 times that of foreign countries, and the water consumption is 2-3 times. Enterprise production and sewage treatment costs

[0004] In the current pre-treatment equipment, the characteristics of various textiles are different, and the pre-treatment process is also different. Generally, the main processes include desizing, scouring, bleaching, mercerizing, singeing, etc. The pre-treatment process is long and there are many washing units. , water and energy consumption, the energy consumption at this stage is about 70% of the total energy consumption in the printing and dyeing finishing process

[0005] In addition, in the pre-treatment equipment, the driving rollers in the washing equipment have high tension, which causes problems such as dimensional instability, wrinkling, and weight deviation. The sewage filter device attached to the equipment is rough and can only filter out larger particles in the washing unit. Substances, the slurry and oil that come off the fabric cannot be completely filtered out, and the treated water cannot be reused
