The invention provides a chlorine gas recovery process in an ionic membrane electrolyzing device. The chlorine gas recovery process is characterized in that chlorine water flowing out of a vacuum system chlorine water cooler and a vacuum pump outlet gas-liquid separator is directly fed into a chlorine water tank by virtue of an inserted pipe and chlorine water from a chlorate decomposition system, a chloride-hydrogen processing step and an anode discharge tank is also fed into the chlorine water tank, next, the chlorine water is pumped to a dechlorination tower by a chlorine water pump and reacts with light salt brine from the outside in the dechlorination tower, the generated chlorine gas is extracted by a vacuum system and fed to a waste gas treatment step, and the chlorine gas in the chlorine water tank is communicated with a chlorine gas main pipe so that the chlorine gas in the chlorine water is recovered. The chlorine gas recovery process in the ionic membrane electrolyzing device ...

A novel method of continuous evaporation to prepare sodium formate is provided. The sodium formate is prepared by processes of: pumping dilute sodium formate into a first-effect evaporator by a feeding pump with the feeding amount being controlled by the liquid level in the first-effect evaporator, allowing the material to flow into a second-effect evaporator due to the potential difference, starting a discharge pump when sodium formate crystals occur in the second-effect evaporator, installing a cyclone hydraulic separator on the outlet of the discharge pump, thickening the material containing solid sodium formate by the cyclone hydraulic separator, discharging the thick material to a discharge tank and returning the dilute material to the evaporators. In this manner, the solid sodium formate is continuously extracted, separated by a centrifugal machine and fed to pneumatic conveying drying to obtain a sodium formate product. The method has characteristics of simple processes, easy operation ...

The invention belongs to the technical field of casting, and relates to a wax pressing device capable of preventing a ceramic core from being broken during wax pressing and a using method of the wax pressing device. The top of the bottom plate is provided with a mold pressing system used for carrying out wax pressing on a ceramic core, a positioning system used for positioning and fixing the head and the bottom of the ceramic core and a coating system used for coating two side walls of the ceramic core with model wax, and the bottom plate is provided with a guide rail used for driving the coating system to move. According to the ceramic core wax pressing device, before wax pressing is conducted on a ceramic core, the coating system is adopted to coat model wax on the surface of the ceramic core, the wax material impact force borne by the ceramic core during wax pressing is reduced, the wax pressing efficiency is improved, and the wax pressing quality is improved. And the shrinkage stress ...
