Description
Technical field
The utility model relates to the device that a kind of embrane method purifying utilizes denim mercerized waste alkali liquid again.
Background technology
The textile industry printing and dyeing will use a large amount of NaOH to handle surface of cotton fabric in the mercerising process, its main process is roughly: at first cotton fabric is placed on to contain in 18～25% the NaOH solution and soaks, with warm water solution cotton fabric is cleaned then, clean with high-temperature-hot-water more at last.In the waste water of immersion and cleaning process generation, all contain NaOH.
In traditional denim mercerized waste alkali liquid emission treatment process, be that all contain alkali waste water with the mercerising process is produced, adopt in sulfuric acid or the hydrochloric acid and after carry out biochemical treatment, materialization treatment process method.Handle and exist following technical disadvantages containing of mercerising process generation in the alkali waste water technology with not enough:
At present in the treatment process, a kind of treatment process is that the alkali waste water that contains that the dyeing mercerizing process produces is all worked as wastewater treatment, use technology biochemical, that discharging is handled in materialization again after adopting acid (sulfuric acid or hydrochloric acid) neutralization, not only high concentration alkali is discharged in vain, but also need a large amount of acid neutralizations, cause the wasting of resources, production cost and processing waste water cost are two high, and have big, the shortcomings such as floor space is big, running cost height of waste water disposal facility investment.Another kind of treatment process can only be at the waste lye that produces in the colourless mercerising process, treatment process is the part waste lye that white embryo cloth mercerising produces to be collected the back concentrate with vaporizer, remove fibre object with ultra-filtration membrane again, utilize again behind the impurity such as cotton fat, slurry, pectin.The main drawback that exists is to handle coloured waste lye that printing and dyeing cloth (particularly denim fabric) mercerising process produces.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of embrane method purifying to utilize the device of denim mercerized waste alkali liquid again, to reduce the commercially available alkali consumption, to reduce production costs, reduces the high-concentration alkali liquor wastewater flow rate, reduces wastewater treatment running cost.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of embrane method purifying utilizes the device of denim mercerized waste alkali liquid again, it is characterized in that it comprises filtration unit and film decolouring impurity removing device, the outlet of described filtration unit is connected with film decolouring impurity removing device inlet pipeline, filtration unit exports on the pipeline that is connected with the import of film decolouring impurity removing device topping-up pump is installed, and the import of filtration unit carries pump outlet to be connected by pipeline and waste lye.
As the utility model improvement of the technical scheme, it also comprises a washing unit, and the outlet of washing unit is connected with the outlet conduit of topping-up pump, the outlet pipe pipe connection of the import of washing unit and film decolouring impurity removing device.
As the utility model further improvement in the technical proposal, be connected with the internal reflux pipeline between the import of topping-up pump and the film decolouring impurity removing device.
On the film decolouring impurity removing device no bleaching alkali lye outlet pipe is installed, no bleaching alkali lye outlet pipe is provided with the external reflux pipeline.
The beneficial effects of the utility model are: 1, reduced the commercially available alkali consumption, reduced production cost.Because original depleted high density salkali waste purifying is utilized again, the alkali of purifying recovery can partly be replaced commercially available alkali on the one hand, has reduced the usage quantity of commercially available alkali like this, thereby reduces consumption of raw materials, reduces production costs, and reaches the purpose of resource reutilization; Reduced the usage quantity of clear water on the other hand simultaneously, year can produce nearly 1,000,000 yuan of direct economic benefit; 2, the alkali lye behind the purifying is identical with the commercially available alkali quality, and the effect behind the denim mercerising is the same with commercially available alkali; 3, reduced the high-concentration alkali liquor wastewater flow rate, used sour dosage thereby reduce neutralization, thereby reduced wastewater treatment running cost; 4, original Technology needs the acid neutralization because of a large amount of salkali waste, the acid-base neutralisation heat release, need bigger equalizing tank before entering biochemistry, so that there is the sufficiently long time to reduce biochemical preceding water temperature, this technology then significantly reduces the waste water disposal facility floor space, strengthen biochemical stability, alleviated original treatment facility load, reduced new production line wastewater facilities input; 5, advocate the production theory of cleaner production, recycling economy, environmental protection.
