Description
Technical field
The invention belongs to textiles sewage disposal device field, be specifically related to a kind of textile dyeing water treatment system.
Background technology
High temperature-pressure dyeing machine mainly dyes that cotton textiles, terylene, acrylic fibers, nylon, wool, polyester-cotton blend, hair are washed, numb cotton or various blended yarn, configuration all kinds creel, can dye multi-form yarn outward, as cheese, reeled yarn spinning cake, loose hair, wool top, beamed yarn, slide fastener, dribbling etc.
High temperature-pressure dyeing machine has following features:
1, circulation staining solution flow is controlled according to coloured differently technological requirement, by main pump frequency conversion speed-adjusting system, reaches and saves the energy and give rational flow, realizes simultaneously dyeing and controls optimization.
2, the liquid of compact conformation stream parallel operation, eliminates commutation and pauses, and has increased cycle-index, makes dyeing more even.
3, low bath raio design, saves dyestuff, auxiliary agent and the energy, reduces blowdown flow rate, increases economic efficiency.
4, can variable load yarn bar, making to hold yarn amount can have through conversion, reaches because of determine bath raio, and elasticity is processed in lifting.
5, scavenger system fast, effectively saves scavenging period and water consumption.
6, overflow-type charging system, can carry out dynamic material, effectively controls reinforced speed and amount, guarantees uniform dye-uptake.
7, adopt novel centrifugal circulation, tool high-performance high efficiency and the saving energy.
The water temperature of dyeing and printing sewage is higher (except sizing and cowboy's rinsing sewage) mostly, if the pulp sewage water temperature of the bleachinging and dyeing of knitted cloth, knitted yarn is 40～45 ℃, the Bleaching and dyeing sewage water temperature of lint, knitting wool is 40～50 ℃, and moving back of Woven Fabrics boiled, dyeing and printing sewage water temperature is 40～50 ℃ etc.When water temperature over-high, can cause sewage biochemical treatment system normally to move, directly affect sewage qualified discharge.Therefore must consider the processing of lowering the temperature of high temperature sewage, then, then the sewage after making to lower the temperature enters biochemical treatment system, to reach the water temperature requirement of biochemical treatment, guarantees the normal operation of whole treatment system.Meanwhile, the heat energy in sewage is also a kind of recycling resource.The method that sewage is lowered the temperature adopts the mode of heat exchange to carry out cooling down conventionally, the process spent water of different temperatures, after mixing, enters the heat exchanger processing of lowering the temperature, and generally water temperature is controlled at below 42 ℃, not only be beneficial to biological growth, can also improve treatment effect.
Cooling water can be used fresh process water, so just utilized a part of heat energy to carry out preheating to production technology water, reduced on the one hand the water temperature of sewage, improved on the other hand the water temperature of production technology water, save the steam that heats fresh process water, reached the object saving production cost.Heat can consider to adopt many heat exchangers design of using in parallel, can guarantee the normal use of heat-exchange system, and heat exchanger can be divided into plate type heat exchanger, pipe heat exchanger etc., and my company is most popular is efficient plate-type heat-exchanger.
In a word, dyeing and printing sewage be that a kind of water yield is large, colourity is high, complicated components, water quality mobility scale is large, temperature is high more difficult organic sewage.In the comprehensive management of technology route of dyeing and printing sewage, the pretreating process of sewage is very important, and it is related to stable operation and the qualified discharge of whole system, also relates to the height of operating cost simultaneously.And sewage carries out after preliminary treatment greatly improving sewage quality, be conducive to dyeing and printing sewage and be for further processing, finally reach the object of removing pollutant.Therefore pretreating process one of key technology that is absolutely necessary in dyeing and printing sewage is processed.
In prior art, textile mills discharge through processing mostly for the sewage of printing and dyeing, even fully just do not process and discharge, and have polluted environment on the one hand, have wasted on the other hand the energy.
