[0002] The concentrated ammonia activated carbon filter is a device that uses activated carbon as a filter medium to remove free matter, microorganisms, some heavy metal ions in water and reduce water chromaticity. It mainly uses the adsorption effect of activated carbon to purify water quality. Activated carbon has a large specific surface area and a developed pore structure, which can effectively adsorb organic matter, residual chlorine, odor and some heavy metal ions in water. It is generally used in the pre-treatment stage of water treatment and desalination systems to protect subsequent equipment such as reverse osmosis membranes and ion exchange resins. The existing filter is generally arranged in the form of a vertically placed reactor. Multiple layers of activated carbon are arranged inside the reactor to adsorb sewage impurities. The adsorption capacity of activated carbon decreases after long-term use, and the activated carbon powder needs to be replaced. The existing treatment measures are generally to open the reactor, and the staff enters the reactor to remove and replace the activated carbon powder. However, the space inside the reactor is small, which is not convenient for replacing the activated carbon. In addition, the ammonia gas volatilized by concentrated ammonia water will also affect the health of the people entering the semi-closed reactor. In order to solve this problem, a new type of concentrated ammonia activated carbon filter is needed. Utility Model Content
