Description
Technical Field
The invention belongs to the technical field of dyeing residual liquid recycling of a dyeing production process system, and particularly relates to an automatic online detection, color measurement and color matching instrument and method for recycling dyeing residual liquid.
Background
The waste water discharged by the printing and dyeing industry accounts for about 35% of the waste water discharged by the whole industry, and main waste liquid in the printing and dyeing industry comprises: desizing waste liquid, scouring waste liquid, bleaching waste liquid, mercerizing waste liquid and dyeing waste liquid. The main problem of the environmental protection in the dyeing industry is to treat dyeing waste liquid, the existing dyeing process technology uses more salt and alkali agents, such as salt (anhydrous sodium sulfate 20-70 g/L) and alkali (sodium carbonate 0.1-25 g/L), the generated waste water has COD (chemical oxygen demand) of up to 2000-4000mg/L and chromaticity of up to 1000-2000 times, and the technology is one of the problems of treatment and automatic detection of the dyeing waste water, especially the dyeing of the deep-blue dye of the black and the deep blue of fabrics, the dye-uptake rate is only about 65%, the discharged residual liquid has up to 35% of dye and high-concentration salt and alkali agents which are discharged into the waste water, and the existing dyeing process technology has extremely high COD of 10000-15000mg/L and extremely high chromaticity of 2000-4000 times, and the existing dyeing process technology brings extremely serious difficulties and pollution to the waste water treatment, the automatic detection of water quality and the environmental protection, so that the treatment strength and the automatic detection degree of the waste water need to be increased, the recycling rate of the waste water and the automatic detection standard of the residual liquid are improved, and the dyeing and the long-term development of the dyeing and dyeing industry are promoted.
The existing method for detecting the dye, salt, alkaline agent, hardness and suspended matters of the dyeing residual liquid is to sample and then detect in a laboratory, and determine the content of the dye in the dyeing residual liquid by using a spectrophotometry; by the weight of GB/T13025.8-2012 in BaCl 2 As a precipitant to form BaSO 4 Precipitation determination of Na 2 SO 4 Is contained in the composition; determining the content of NaCl by using a molar silver content method of GB/T9729-2007; determining the sodium carbonate content of the residual liquid by using a GB/T210.2-2004 acid-base titration method; the hardness is measured by using GB7477-87EDTA capacity method; the method adopts GB 11901-89 filtration 105 ℃ drying method to measure SS, the detection means is non-automatic on-line detection, the detection time is long, the recycling times are few, the discharged effective dye, salt and alkaline agent are more, the production cost and the cost for treating waste concentrated solution are larger, the limitation is still very large, although the spectrophotometry detection method for recycling residual liquid in the prior art is single, the defects of automatic on-line monitoring of the dye effective rate and the adding amount, the salt effective rate and the adding amount, the alkali effective rate and the adding amount, the defects of limited recycling times, incapability of automatically determining the relevant color characteristic value of the fabric on line and the like are overcome, and the defects of long detection analysis period, poor reproducibility of detection results, influence on dyeing technology and normal production and the like are particularly overcome.
The development trend of the existing printing and dyeing residual liquid detection technology in the printing and dyeing industry at home and abroad is automatic, efficient and accurate, and the three aspects complement each other, so that the application of an automatic, efficient and accurate online detection instrument and a method thereof in the printing and dyeing residual liquid detection technology is imperative.
CN111006929a discloses a device and method for rapidly calculating dye supplement amount for recycling dyeing residual liquid. The device comprises a filter, a cooler, a circulating pump, a spectrophotometer, a cylinder attached to the end of the pipeline, wherein the filter, the cooler, the circulating pump and the spectrophotometer are sequentially connected with the pipeline in an end-to-end mode, a weighing device for weighing the quality of the dyeing residual liquid is arranged at the bottom of the cylinder attached, firstly, the required concentration-absorbance working curve of basic dye under different wavelength light rays is drawn, the device is directly arranged on the cylinder attached to the residual liquid of the dyeing machine, the residual liquid is detected on line, the absorbance of a plurality of wavelength light rays is detected, the concentration of the residual liquid corresponding to each wavelength absorbance is obtained according to the concentration-absorbance working curve of the basic dye, the concentration average value is taken, the dye quantity required to be added is calculated according to the concentration average value of the dyeing residual liquid and the concentration and the total quantity of the original dyeing liquid, the dye is added for recycling, the dyeing chromatic aberration of the recycling liquid can be effectively reduced, and the detection is more convenient. However, the method is single, can not effectively and automatically monitor the dye effective rate and the adding amount, the salt effective rate and the adding amount, and the alkali effective rate and the adding amount on line, and has the main defects of limited recycling times, incapability of automatically determining the relevant color characteristic values of the fabrics on line, and the like.
CN101475227a discloses a method for recycling and recovering dyeing residual liquid and a special treatment tank for dyeing residual liquid, which discloses the following steps: a. a desired concentration-absorbance working curve of the base dye is made: preparing a series of dilute solutions of required basic dyes, respectively, measuring the absorbance of a certain dilute solution in the series of the concentrations of each dye one by using a spectrophotometer under different wavelengths (380-780 nm), respectively taking an absorption spectrum curve of the basic dye, finding out the maximum absorption wavelength of each dye, and taking the absorbance of the dilute solution of the series of the concentrations as a concentration-absorbance working curve under the maximum absorption wavelength corresponding to each dye; b. calculating the amount of each color matching dye contained in the dyeing residual liquid: measuring the absorbance of the dye used in the production prescription in the dyeing residual liquid at the maximum absorption wavelength by using a spectrophotometer, searching the concentration of the dye corresponding to the absorbance on a concentration-absorbance working curve of the corresponding dye, and calculating the content of each blended dye in the residual liquid; c. recycling dyeing residual liquid for production: adding dyes into the dyeing residual liquid according to the content of each mixed dye in the dyeing liquid until the content of each dye in the dyeing residual liquid meets the production visit requirement, and returning the dyeing residual liquid to production after the sample is qualified; the sample is unqualified, the content of basic dye in the dye liquor is adjusted until the sample is qualified, and the dyeing residual liquid is reused for production; that is to say, by measuring the absorbance of the residual liquid under the maximum absorption wavelength, a certain error exists in the method for supplementing the dye according to the absorbance calculation, so that the small sample can be used for production only after being dyed in the step c, the method is more complicated to use, the adding amount of the dye is required to be adjusted later, the adding amount of the dye is inaccurate, and the color difference of the dyed reuse liquid is increased; and in the detection of the residual liquid, the residual liquid is generally required to be sampled and then measured in a laboratory.
In view of this, the present invention has been made.
