| titleOfInvention | Sodium naphthalene sulfonate apparatus for producing |
| abstract | The utility model discloses a sodium naphthalenesulfonate apparatus for producing, including refined naphthalene groove, sulfuric acid tank, sulfonation reaction pump, multistage sulfonation reaction ware and filter equipment, multistage sulfonation reaction ware is established ties in proper order, refined naphthalene groove and sulfuric acid tank pass through the sulfonation reaction pump and connect first order sulfonation reaction ware, and last order sulfonation reaction ware exit linkage filter equipment; the flushing nozzle supplies waterThe pipe is connected with a water source through a water pump; the filtering device comprises a rack and a plurality of filter plates, a material receiving table is arranged below the rack, a plurality of drain holes are formed in the center of the material receiving table, the baffles on the two sides of the material receiving table are clamped with the scraping plates, and the driving mechanism drives the scraping plates to scrape on the upper surface of the material receiving table; a bracket is further arranged above the rack, and a flushing device is arranged on the bracket. The device has the advantages of full sulfonation reaction, high product purity, and reduction of water content in the filter cake by using a filter pressing mode, thereby reducing the impurity Na 2 SO 4 The amount of (c). |
