Description
Technical field
The utility model relates to field of textile machinery, especially the environment-friendly type textile machine.
Background technology
Mercerizing thread is one of main raw material during grade textiles is produced, and is applied to that top grade is taken, household textiles, receives extensively liking of people.The key step of producing mercerizing thread has sequentially: caustic dip, crowded alkali, high temperature washing, middle Warm Wash, normal temperature washing, oven dry.These processing steps all carry out in same mercerizing range except that oven dry.Successively feed mercerising aqueous slkali, high-temperature water, middle warm water, normal-temperature water respectively and operate, per step all will be discharged the waste liquid after the use respectively, contain certain density alkali waste water so in the mercerising process, can produce.Producing 30 tons of waste water with mercerized yarn per ton calculates; One family produces the factory of 5000 tons of mercerized yarns per year, can generate 150,000 tons of mercerizing waste waters every year, and these waste water all are to be discharged in the purification tank for liquid waste at present; Alkalinity about 10%; Need to add an amount of acid and carry out neutralisation treatment, reach neutral back and drained, such treatment process causes a large amount of water, alkali resource and energy waste.
The utility model content
The purpose of the utility model is for providing a kind of both environmental protection, can also practice thrift process without drainage of waste water device in a kind of mercerizing thread production process of big water gaging, alkali resource and the energy.
The technical scheme that realizes the foregoing invention purpose is following:
The process unit of wastewater zero discharge in a kind of mercerizing thread production process; Have mercerizing range, high temperature supply tank, middle temperature supply tank, normal temperature supply tank and alkali lye separator; The delivery port of high temperature supply tank, middle temperature supply tank, normal temperature supply tank is connected with the water inlet of mercerizing range through pipeline respectively; The waste liquid outlet of mercerizing range connects waste pipe and three pipelines of high temperature washing back waste pipe behind normal temperature washing back waste pipe, the middle Warm Wash through pipeline, and middle through the solenoid control switch, normal temperature washing back waste pipe links to each other with the import of middle temperature supply tank; Waste pipe links to each other with the import of high temperature supply tank behind the middle Warm Wash; High temperature washing back waste pipe links to each other with the import of alkali lye separator, and alkali lye separator condensation-water drain links to each other with the import of normal temperature feed cistern through pipeline, perhaps is connected to dyeing and waits in the arranging process; The outlet of alkali lye separator high alkali liquid links to each other with the import of mercerizing range alkali lye through pipeline, and the heat energy pipeline of hot water outlet is connected to high temperature supply tank and middle temperature supply tank respectively.
Further, water purification is housed and replenishes pipe on the normal temperature supply tank.
In middle temperature supply tank and high temperature supply tank, heater is housed.
The alkali lye separator has heater and condensing unit.
When mercerizing thread was produced, yarn was earlier 23% mercerising treatment fluid processing through alkalinity, extracts again; Carry out high temperature washing, middle Warm Wash, normal temperature washing then successively, remove the alkali that contains in the yarn, the waste water alkalinity after the normal temperature washing is lower; Alkali concn＜1%, the waste water alkalinity behind the middle Warm Wash is higher, the about 2-8% of alkali concn; Waste water alkalinity after the high temperature washing is the highest, reaches 5-15%.Therefore, warm supply tank in can the waste water after the normal temperature washing being imported, in being heated to supply water as the middle temperature of next group mercerization in the temperature back; Waste water behind the middle Warm Wash is imported the high temperature supply tank, be heated to that the high temperature as the next group mercerization supplies water behind the high temperature; With the high hot waste water of high temperature washing back alkalinity; Introduce the alkali lye separator, in the alkali lye separator, carry out evaporation and concentration, the water vapour that evaporation obtains is condensed into alkali free condensed water in condensing unit; The normal temperature of condensed water as the next group mercerization is supplied water; Also can make his usefulness in addition, the high alkali liquid after the separation joins in the mercerizing range through pipeline, and the alkalinity of alkali lye is adjusted to 23%; As next group mercerising treatment fluid, the hot water of generation is used for the heating of high temperature and warm supply tank through the heat energy converter.Guaranteed that from the structure of above equipment the flow process of technological process and washings, the alkali lye of yarn is reverse carrying out each other; With the minimum yarn of pure water washing alkalinity; Then to hang down the yarn of the higher alkalinity of water washing of alkalinity; The waste liquid of maximum concentration separates water outlet and alkali, and water and alkali carry out reuse respectively again, and yarn per ton can be practiced thrift recovery waste water and reach 30 tons.
Above technology is illustrated in and has realized wastewater zero discharge and energy recovery utilization, and water and alkali resource have all obtained making full use of times without number.The energy also is fully used; The temperature water supply in heating just becomes slightly of normal temperature waste water; Warm effluent just becomes high temperature through heating slightly again and supplies water, and hot waste water just can come out water evaporates through heating in the alkali lye separator slightly, and heat energy also is fully used; Therefore practiced thrift the energy widely, eliminated thermal pollution environment.
The utility model except reach environmental protection, economize on resources and the goal of the invention of the energy, have also that equipment is simple, a processing ease, beneficial effect that cost is low.
