Continuously-operated activated carbon adsorption tower

Abstract

The invention belongs to water purification equipment in the field of equipment and safety environmental protection and particularly relates to a continuously-operated activated carbon adsorption tower. The continuously-operated activated carbon adsorption tower consists of a cylinder body provided with a water inlet and a sample fetching opening, a discharging hopper, more than two porous plates fixed in the cylinder body, a water discharging device and a water collecting groove; the water inlet is located below the porous plate on the bottommost layer; the water discharging device and the water collecting groove are located above the cylinder body; a discharging opening is arranged at the bottom of the discharging hopper and the discharging opening is provided with a discharging valve; the porous plates are uniformly provided with special filtering water caps and the gaps of the special filtering water caps need to be less than grains of filtering materials; each porous plate is further provided with hoisting switching devices corresponding to holes on the porous plate; the hoisting switching devices of each porous plate are respectively fixedly arranged on a connecting rod which stretches to a tower top and can move up and down; and grain activated carbon with the certain thickness is filled on each porous plate to be used as the filtering materials. The continuously-operated activated carbon adsorption tower disclosed by the invention mainly can be used for solving the defects of a traditional activated carbon filtering tower and has the functions of sufficiently expressing the adsorption capability of the activated carbon, replacing the filtering materials and carrying out backwashing without stopping a machine, realizing the automatic replacing of the activated carbon in batches and the like.

Description

technical field [0001] The invention belongs to water purification equipment in the field of equipment and safety and environmental protection, in particular to a continuously operating activated carbon adsorption tower. Background technique [0002] The capillary inside the activated carbon particle is developed, and the specific surface area is large, which can absorb colloid, organic matter, oil and other substances. Activated carbon adsorption towers are widely used in water treatment for the removal of organic matter (oil), decolorization, and removal of oxidative substances to meet the requirements of different water use in production and life or to meet the requirements of environmental protection during discharge. During the contact process between water and activated carbon, the pollutants in the water are transferred to the surface of activated carbon through adsorption, and then migrate to the interior of activated carbon particles through capillary channels to ac...

AI Technical Summary

Problems solved by technology

Such an operation procedure: first, there must be a considerable part of the replaced activated carbon with adsorption capacity, all of which are replaced without being able to make the best use of them, wasting resources, and the operating cost is high; second, the replacement needs to be shut down, The continuous operation of the system can only be guaranteed by putting in spare equipment

Backup equipment not only increases the floor area, but also requires a high initial investment; thirdly, after the traditional activated carbon filter traps suspended solids in the water, it needs to be shut down regularly for backwashing, and backwashing needs to consume part of the clean water, which reduces the actual processing capacity of the equipment
