Embodiment Construction
[0016] like figure 1 As shown, the precision microporous thin-layer filtration process of salt water used in alkali production in the embodiment of the present invention includes the following devices: regeneration liquid storage tank 1, brine stock solution storage tank 2, air filter 3, air compressor 4, compressed air storage tank 5 , Precision microporous filter 6, thickened filter residue storage tank 7, centrifugal pump 8, and PLC interlocking full automatic control device. The precision microporous filter 6 is the main equipment of this process. It consists of three parts. The upper part is a cylindrical shell with an elliptical arc-shaped head, which is used as an intermediate storage room for filtrate or compressed air; the middle part is a cylindrical shell. The upper and middle shells are connected by a pair of flanges, and a porous flower plate is sandwiched between the upper and lower flanges. The rigid sintered microporous filter tube is fixedly connected to the h...
