The invention discloses a demineralizing, purifying and filtering device in epoxy resin production. A material inlet is arranged on the upper part of a filter. A material outlet pipe / vacuum joint is arranged on the lower part of the filter. An upper set, a middle set and a lower set of filter cores are arranged in the filter. The first set of filter core is arranged on the lower part in a horizontal paving form. The second set of filter core is arranged on the first set of filter core and the third set of filter core, a filtering medium adopts a wax filter core, and the wax filter core is connected with a first filter liquor collecting pipe. The third set of filter core adopts a leaf filtering plate as the filtering medium, and the leaf filtering plate is vertically arranged between the first set of filter core and the third set of filter core and connected with a second filter liquor collecting pipe. An upper and a lower nitrogen / dry steam inlets are arranged on the filter and connected with a nitrogen boiling bed. The invention has reasonable structure, can ensure the separation of salt, aged resin and epoxy resin, and has no influence on the production process and the product quality of the epoxy resin.
Description
Technical field: [0001] The invention relates to a desalination, purification and filtration device in the production of epoxy resin. Background technique: [0002] In the production process of epoxy resin, a large amount of salt (salt particle size of 200-300 mesh) is produced and mixed with the aging resin in the resin solution, making the resin salt solution in a paste state, and it is difficult to separate the salt and the resin by conventional methods . [0003] In the existing epoxy resin production, the salt purification process is: add a certain amount of water and toluene. The resin is dissolved in toluene, the salt is dissolved in water, and the salt is transferred from the organic phase to the inorganic phase by using the toluene resin solution insoluble in the saline solution to separate the salt. The separated salt solution enters the water phase, and after treatment by wastewater purification, evaporation, incineration spraying, biochemical treatment and othe...
