Modularized electrolytic seawater dehydrogenation module with dehydrogenation function and antifouling device

Abstract

The invention provides a modularized electrolytic seawater dehydrogenation module with a dehydrogenation function and an antifouling device, and belongs to the technical field of electrochemical electrolysis antifouling. The hydrogen elimination module is based on a two-step hydrogen elimination technology, comprises a gas-liquid separation technology for separating hydrogen from seawater and a hydrogen elimination technology for eliminating hydrogen by using a platinum-palladium catalyst, and mainly comprises a gas-liquid separation unit, a hydrogen elimination reactor unit, a detection unit and a cooling unit, the device is used for separating and eliminating H2 generated by electrolysis of a cathode in the seawater electrolysis process. Wherein the gas-liquid separation unit adopts a physical method, and H2 is separated from a seawater medium under the action of centrifugal force or gravity; wherein the dehydrogenation reactor unit adopts a platinum-palladium catalyst to enable H2 and O2 to rapidly react to generate H2O, and the H2O generated by the reaction is guided back into a seawater pipeline; wherein the detection unit adopts an H2 sensor to monitor the concentration of residual H2 so as to ensure that the absorption rate of H2 meets the requirement.

Description

technical field [0001] The invention relates to a modularized electrolytic seawater hydrogen elimination module and an antifouling device with hydrogen elimination function, and belongs to the technical field of electrochemical electrolysis antifouling. Background technique [0002] Marine biofouling is an important problem restricting the operation of ships. On the one hand, marine biofouling is commonly found in hulls, propellers, and seawater pipelines. Once it occurs, it will cause many problems such as reduced speed, blocked pipelines, reduced heat transfer efficiency, induced corrosion, and increased noise. In severe cases, it will threaten On the other hand, the International Maritime Organization (IMO) has strict management requirements for the discharge of ballast water from ocean-going ships to prevent the invasion of alien species and the spread of pathogens. Therefore, corresponding technical measures must be taken to prevent and control marine organisms. [00...
