Description

Anti-hardening and anti-blocking device for carbon layer of pulsating bed

Technical Field

The utility model relates to a quality of water clarification plant technical field, concretely relates to pulsation bed charcoal layer prevents hardening jam device.

Background

Water is the basis of human survival, with the continuous development of human society, environmental pollution becomes increasingly serious, water quality of a water body is increasingly deteriorated, and human beings face serious situations of water pollution and water shortage. The discharge of industrial sewage is a great important factor of water pollution, and therefore, the treatment of industrial sewage and the full recycling of water resources become important jobs in modern industrial production. The sewage purification treatment is generally realized by a sewage purifier. The existing fixed bed adopts the form of water outlet under the water inlet.

In recent years, urban economic construction in China is rapidly developed, and sewage and wastewater of life and production are increasingly improved along with improvement of living standard of residents. With the increasing requirements of China on environmental protection, the requirements on treatment of urban production and domestic sewage are more and more strict, and because the activated carbon has a large specific surface, a multifunctional adsorption site and an abundant surface chemical structure, the activated carbon has high physical adsorption and chemical adsorption functions on most common organic pollutants and heavy metal ions, and is a common process for removing COD or organic matters from wastewater. Especially, the method is used for removing organic pollutants which are difficult to be biochemically and chemically removed after chemical precipitation, biological treatment and other processes. Therefore, the carbon adsorption pulsating bed is widely applied to sewage treatment upgrading reconstruction.

The common forms of the activated carbon adsorption bed include a fixed bed and a pulsating bed. The carbon layer of the pulsating bed and the fluid are in a reverse motion mode, the saturated carbon layer is intermittently moved out of the adsorption tower to enter a subsequent regeneration process unit, and then the regenerated carbon and the supplemented new carbon are added into the adsorption tower again from the top of the tower. Therefore, theoretically, the pollutant components of the treated liquid are always contacted with a 'fresh' active carbon layer (namely, the adsorption performance is the same as the performance of the new carbon layer), even if the pollutant components or the concentration fluctuates violently and the mass transfer area becomes long, the whole bed layer height in the active carbon adsorption pulsation bed is the new active carbon, the adsorption performance is strong, the phenomenon that the carbon layer is penetrated is not easy to occur, and the quality of the effluent can be ensured to be still in a stable standard state.

The granular activated carbon has the advantages of strong adsorption capacity on heavy metal ions such as COD, phenols, cyanides, chromium, zinc, nickel and the like and other toxic and harmful organic compounds, and can be repeatedly recycled, and is increasingly widely applied to the fields of food, medicines, chemicals, sewage treatment and the like.
