Abstract
The invention discloses a method for achieving long-term operation of a fusion bisphenol A prilling nozzle through glass fiber filtering. A bisphenol A fusion solution containing impurities such as high-temperature carbide of positive ion exchange resin powder is conveyed into a first filter and a second filter, the first filter and the second filter are complementary and are respectively provided with an alkali-free glass fiber filter element, the first filter and the second filter are used alternately, only one filter is used normally, the high-temperature carbide and other impurities are attached to the surfaces of the alkali-free glass fiber filter elements, and the bisphenol A fusion solution without the high-temperature carbide and other impurities is conveyed into the prilling nozzle of a prilling tower. According to the method, smoothness of a small hole, which is about 0.7 mm in diameter, of the prilling nozzle is effectively guaranteed.
Description
Technical field
The present invention relates to one and filter with glass fibre the melting bisphenol-A prilling nozzle long-term operation method that realizes.
Background technology
With phenol, acetone is in the cation exchange resin processes bisphenol-a-production process of raw material, cationic ion-exchange resin in use there will be a small amount of fragmentation, form fragment or broken end, although these materials are removed by the filter after reactor, but still escape out by filter in some small broken ends, with reacted phenol, bisphenol-A solution enters follow-up unit, under high-temperature technology situation, the broken end of escaping can bond by high temperature cabonization, and enter in granulation tower nozzle with the bisphenol-A solution of melting, in the aperture of the diameter 0.7mm of nozzle, stop up, cause the discharging of melting bisphenol-A not smooth, granulation tower need arrange to stop, dismantle prilling nozzle and soak with acetone the nozzle aperture that cleaning is stopped up.
Summary of the invention
The object of the present invention is to provide a kind of unobstructed filtering and realize melting bisphenol-A prilling nozzle long-term operation method with glass fibre of prilling nozzle diameter that ensure.
Technical solution of the present invention is:
One filters with glass fibre the melting bisphenol-A prilling nozzle long-term operation method that realizes, it is characterized in that: the bisphenol-A fused solution of the impurity such as the pyrocarbon compound that contains the broken end of cationic ion-exchange resin is sent into the first filter that alkali-free glass fibre filter core is housed and the second filter for subsequent use each other, the first filter and the second filter rotation are used, normal use is 1, the impurity such as pyrocarbon compound stick to glass fibre cartridge surface, remove the bisphenol-A fused solution of the impurity such as pyrocarbon compound and send in the prilling nozzle of granulation tower.
Described the first filter and the second filter that alkali-free glass fibre filter core is housed, it is the alkali-free glass fibre filter core that φ 65mm, length are 1016mm that 18 diameters are all equipped with in its inside, alkali-free glass fibre filter core precision is 30 microns.
The present invention has effectively ensured the unobstructed of prilling nozzle diameter 0.7mm aperture, the present invention installs the inner filter that glass fibre filter core is housed on the feeding line of melting bisphenol-A granulation tower nozzle, material is by after glass fibre filter element filtering, carbide impurity is adhered to glass fibre cartridge surface, bisphenol-A fused solution penetrates glass layer, enter granulation tower nozzle, the carbide impurity adhering to along with glass fibre cartridge surface increases, bisphenol-A fused solution penetrates the resistance increment of glass layer, the material turnover differential pressure of filter rises, in the time flowing through the bisphenol-A fused solution flow of filter and can not meet need of production, reserve filter is come into operation, inactive filter replacement glass fibre filter core.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the schematic diagram of one embodiment of the invention.
Detailed description of the invention
The bisphenol-A fused solution of the impurity such as the pyrocarbon compound that contains the broken end of cationic ion-exchange resin is sent into the filter that glass fibre filter core is housed 1 for subsequent use each other and filter 2, filter 1 and filter 2 rotations are used, normal use is 1, the impurity such as pyrocarbon compound stick to glass fibre cartridge surface, remove the bisphenol-A fused solution of the impurity such as pyrocarbon compound and send in the prilling nozzle 3 of granulation tower 4.The bisphenol-A feeding line of 5 impurity such as be the pyrocarbon compound that contains the broken end of cationic ion-exchange resin in figure; In figure, 6 is bisphenol-A product.
Service condition:
The bisphenol-A fused solution of the impurity such as the pyrocarbon compound that contains the broken end of cationic ion-exchange resin is sent into the filter that glass fibre filter core is housed, 18 glass fibre filter cores that are of a size of φ 65 × 1016 are equipped with in inside, glass fibre filter core precision is 30 microns, can filter out pyrocarbon compound impurity, avoid the aperture clogs of prilling nozzle diameter 0.7mm, avoid occurring because of the unplanned parking phenomenon of cleaning during shutdown prilling nozzle aperture.
Claims (2)
1. one kind is filtered with glass fibre the melting bisphenol-A prilling nozzle long-term operation method that realizes, it is characterized in that: the bisphenol-A fused solution of the impurity such as the pyrocarbon compound that contains the broken end of cationic ion-exchange resin is sent into the first filter that alkali-free glass fibre filter core is housed and the second filter for subsequent use each other, the first filter and the second filter rotation are used, normal use is 1, the impurity such as pyrocarbon compound stick to glass fibre cartridge surface, remove the bisphenol-A fused solution of the impurity such as pyrocarbon compound and send in the prilling nozzle of granulation tower.
2. according to claim 1ly filter and realize melting bisphenol-A prilling nozzle long-term operation method with glass fibre, it is characterized in that: described in the first filter and second filter of alkali-free glass fibre filter core are housed, it is the alkali-free glass fibre filter core that φ 65mm, length are 1016mm that 18 diameters are all equipped with in its inside, and alkali-free glass fibre filter core precision is 30 microns.
