Abstract
The utility model discloses a polyethylene glycol filtering and purifying device which comprises a fine filter, an ultrafilter, a first exchange tower, a second exchange tower and a third exchange tower connected in series sequentially. Hollow fiber filter elements are arranged in the fine filter and/or ultrafilter, the first exchange tower is a cationic resin exchange tower and filled with D001 macroporous strong-acid cation-exchange resin. The second exchange tower is an anionic resin exchange tower and filled with D301 macroporous weak-base anion-exchange resin. The third exchange tower is an anionic resin exchange tower and filled with D201 macroporous weak-base anion-exchange resin. Based on original ion exchange, according to the device, after fine filtration and ultrafiltration, resin models in an exchange column are changed, so that the device has the advantages of large exchange volume, good oxidation resistance and strong organic contamination resistance, and absorbs impurity ions in a polyethylene glycol solution more deeply to improve the purity of a recovered solution, so that the recovered solution meets the demands of a photovoltaic electron production process.
Description
Technical field
The utility model relates to the used cutting liquid recovery and utilization technology in the silicon chip processing, is specifically related to a kind of polyoxyethylene glycol and filters purifying plant.
Background technology
In the prior art, be used for polyglycol solution that photovoltaic electronic industry section lubrication uses recycle contaminated after, adopt the form purification of positive resin exchange tower (interior filling 001X7 sun resin), negative resin exchange column (interior filling D301 negative resin) and positive resin exchange tower (interior filling 001X7 sun resin) three posts series connection.
When polyglycol solution in Continuous Flow behind three towers, the positive and negative foreign ion in the solution by resin absorption after, the purifying polyglycol solution of outflow is back to the charging of later process.
Its shortcoming is that the purifying polyglycol solution of outflow also contains partial impurities owing to filtered, and technique is unstable in addition, and the solution after often can occurring purifying does not still meet the charging requirement of next procedure.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, provides a kind of on original ion exchange process basis, by after smart filter and the uf processing, selects more novel exchange resin first again, makes the polyoxyethylene glycol purity of output higher.
For achieving the above object, the technical solution of the utility model is that a kind of polyoxyethylene glycol of design filters purifying plant, described filtration purifying plant comprises secondary filter, ultra-fine filter, the first exchange column, the second exchange column and the 3rd exchange column of successively series connection, it is characterized in that, in described secondary filter and/or ultra-fine filter, be provided with the tubular fibre filter core, described the first exchange column is positive resin exchange tower, loads D00l macroporous type strong-acid cation-exchange resin; Described the second exchange column is the negative resin exchange column, loads D301 macroporous type weak base anion-exchange resin; Described the 3rd exchange column is the negative resin exchange column, loads D201 macroporous type strongly basic anion exchange resin.
Wherein preferred technical scheme is that the exchange resin of loading in the first exchange column, the second exchange column and the 3rd exchange column is macroporous type vinylbenzene ion exchange resin.
Advantage of the present utility model and beneficial effect are: this polyoxyethylene glycol filters purifying plant on original ion-exchange basis, first by after smart filter and the uf processing, change again the resin model in the exchange column, polyoxyethylene glycol can fall most of undissolved Impurity removal of determining first after the filtration treatment of secondary filter and ultra-fine filter.And then carry out ion-exchange with the macroporous type vinylbenzene ion exchange resin of three kinds of different models, the common trait of these macroporous type vinylbenzene ion exchange resin is: have that exchange capacity is large, antioxidant property good, the strong advantage of anti-organic contamination ability, the foreign ion in the absorption polyglycol solution of the degree of depth more, improve the purity that reclaims solution, the pH value that can adjust simultaneously solution is 8 ~ 9, to guarantee to reclaim the needs that solution satisfies photovoltaic electronics production technique.
Description of drawings
Fig. 1 is the structural representation that the utility model polyoxyethylene glycol filters purifying plant.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, the utility model is that a kind of polyoxyethylene glycol filters purifying plant, this filtration purifying plant comprises secondary filter 1, ultra-fine filter 2, the first exchange column 3, the second exchange column 4 and the 3rd exchange column 5 of successively series connection, in described secondary filter and/or ultra-fine filter, be provided with the tubular fibre filter core, the first exchange column is positive resin exchange tower, loads (vertical chemical industry company limited produces such as east, Bangbu) D00l macroporous type strong-acid cation-exchange resin; The second exchange column is the negative resin exchange column, loads (producing such as Shanghai Su Ke chemical industry company limited) D301 macroporous type weak base anion-exchange resin; The 3rd exchange column is the negative resin exchange column, loads (producing such as the Wan Dong of Anhui Province resin processing plant) D201 macroporous type strongly basic anion exchange resin.
Preferred embodiment is that the exchange resin of loading in the first exchange column, the second exchange column and the 3rd exchange column is macroporous type vinylbenzene ion exchange resin in the utility model.
The common trait of employed these macroporous type vinylbenzene ion exchange resin of the utility model is: have that exchange capacity is large, antioxidant property good, the strong advantage of anti-organic contamination ability; The D201 macroporous type strong anion-exchange resin of particularly loading in the 3rd exchange column 5 anion beds when the remaining anionic impurity of absorption, can discharge the alkali of trace, take the pH value that improves pure solution as 8 ~ 9, satisfies new processing requirement.
The utility model adopts the polyglycol solution after smart filter, ultrafiltration and ion exchange method technique are purified; can successfully be back to the section lubrication operation of photovoltaic electronic industry; greatly reduce production cost; reduced simultaneously the output of useless polyoxyethylene glycol; really accomplish energy-saving and emission-reduction, effectively protected ecotope.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
