Disclosed are an ultrahigh-pressure
sodium hypochlorite generator and a preparation method of
sodium chlorate. The ultrahigh-pressure
sodium hypochlorite generator comprises a shell with a water inletand a water outlet, a plurality of
cathode pressing plates and a plurality of
anode plates which are sequentially stacked at intervals are arranged in the shell, and the
cathode pressing plates and the
anode plates are provided with center holes. A center shaft penetrates through the center holes to position and press the
cathode pressing plates and the
anode plates to form a disc type structureand block the cathode pressing plates and the anode plates at the positions of the center holes. Strong brine enters from the water inlet, sequentially flows back between the cathode pressing plates and the anode plates to form a passage and flows out from the water outlet. The reaction
mass transfer efficiency and the
reaction path are increased by utilizing the disc type design, and the reactionefficiency of
sodium hypochlorite production is improved; the electrodes adopt a cathode and anode staggered lamination mode, so that the reaction efficiency is enhanced; and the reactor shell and the internal electrodes adopt a high-pressure sealing mode, so that the
dissolution rate of
chlorine can be effectively improved, and
chlorine leakage is avoided. The method has good sodium hypochloriteproduction capacity, and can significantly improve the concentration of
sodium hypochlorite in water.
