Abstract
The invention discloses one and realize melting bisphenol-A prilling nozzle long-term operation method with glass fiber filter, the bisphenol-A fused solution of the impurity such as the pyrocarbon compound containing the broken end of cationic ion-exchange resin is sent into the first filter that alkali-free glass fibre filter core is housed for subsequent use each other and the second filter, first filter and the second filter rotation use, normal use is 1, the impurities adhere such as pyrocarbon compound are in glass fibre cartridge surface, and the bisphenol-A fused solution removing the impurity such as pyrocarbon compound is sent in the prilling nozzle of granulation tower.The present invention effectively ensure that prilling nozzle diameter is about the unobstructed of 0.7mm aperture.
Description
Technical field
The present invention relates to one and realize melting bisphenol-A prilling nozzle long-term operation method with glass fiber filter.
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 filter after the reactor, but still escape out by filter in some small broken ends, with reacted phenol, bisphenol-A solution enters subsequent cell, 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, be about at the diameter of nozzle in the aperture of 0.7mm and block, cause the discharging of melting bisphenol-A not smooth, granulation tower need arrange to stop, dismantle prilling nozzle and soak the nozzle orifice clearing up blocking with acetone.
Summary of the invention
The object of the present invention is to provide a kind of ensure prilling nozzle diameter unobstructed realize melting bisphenol-A prilling nozzle long-term operation method with glass fiber filter.
Technical solution of the present invention is:
One realizes melting bisphenol-A prilling nozzle long-term operation method with glass fiber filter, it is characterized in that: the bisphenol-A fused solution of the impurity such as the pyrocarbon compound containing the broken end of cationic ion-exchange resin is sent into the first filter that alkali-free glass fibre filter core is housed for subsequent use each other and the second filter, first filter and the second filter rotation use, normal use is 1, the impurities adhere such as pyrocarbon compound are in glass fibre cartridge surface, and the bisphenol-A fused solution removing the impurity such as pyrocarbon compound is sent in the prilling nozzle of granulation tower.
Described the first filter and the second filter that alkali-free glass fibre filter core is housed, the alkali-free glass fibre filter core that 18 diameters are φ 65mm, length is 1016mm is all equipped with in its inside, and alkali-free glass fibre filter core precision is 30 microns.
The present invention effectively ensure that prilling nozzle diameter is about the unobstructed of 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 adhered to along with glass fibre cartridge surface increases, the resistance that bisphenol-A fused solution penetrates glass layer increases, the material turnover differential pressure of filter rises, when the bisphenol-A fused solution flow flowing through filter can not meet need of production, reserve filter is come into operation, the filter replacement glass fibre filter core of stopping using.
Accompanying drawing explanation
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 containing the broken end of cationic ion-exchange resin is sent into the filter 1 that glass fibre filter core is housed for subsequent use each other and filter 2, filter 1 and filter 2 rotation use, normal use is 1, the impurities adhere such as pyrocarbon compound are in glass fibre cartridge surface, and the bisphenol-A fused solution removing the impurity such as pyrocarbon compound is sent in the prilling nozzle 3 of granulation tower 4.In figure, 5 is the bisphenol-A feeding line of the impurity such as pyrocarbon compound containing the broken end of cationic ion-exchange resin; In figure, 6 is bisphenol-A product.
Service condition:
The bisphenol-A fused solution of the impurity such as the pyrocarbon compound containing the broken end of cationic ion-exchange resin is sent into the filter that glass fibre filter core is housed, the glass fibre filter core that 18 are of a size of φ 65 × 1016 is equipped with in inside, glass fibre filter core precision is 30 microns, pyrocarbon compound impurity can be filtered out, avoid prilling nozzle diameter to be about the aperture clogs of 0.7mm, avoid the unplanned parking phenomenon because of cleaning during shutdown prilling nozzle aperture to occur.
