Powdered activated carbon often accumulates in the center of the funnel, forming the phenomenon of blocking the falling materials, so that the added activated carbon can not pass through. Whenever this happens, it is necessary to change the skew viewpoint of the lower part of the funnel to make the skew of the lower part of the funnel steeper, so that the participating activated carbon can fall smoothly. Generally speaking, the charging of activated carbon is carried out by an ejector, but attention should be paid to the wear degree of activated carbon on the rotary charging valve or ejector when charging. Therefore, the above sprayer or rotary inflation valve should be thoroughly overhauled at least once every six months.
The amount of powdered activated carbon can be measured in two ways. One is the capacity method; The other is the component method. However, the former method needs to reflect the density and moisture, and the latter method needs to measure the moisture content of activated carbon first, and then correct it separately, otherwise the real feeding amount cannot be calculated. In addition, there is a method of making activated carbon into slurry and then using a quantitative pump to participate. If you choose this method, you need to adjust the fineness of the slurry accurately.
In a certain range, the adsorption and decontamination of powdered activated carbon should be ensured as much as possible, which is not only related to the treatment effect, but also closely related to the cost of water production. The whole equipment or system for the storage, manufacture and dosing of powdered activated carbon based on appropriate parameters must be able to well prevent unstable factors in each link, such as blockage during transportation and dosing, from causing unstable flow, thus affecting the decontamination effect.
Powdered activated carbon is easy to fly away, so we should pay close attention to its operation and management. Pay special attention to the method of selecting charging equipment. In order to improve the working environment and work efficiency, active charging equipment is generally selected. Activated carbon is sometimes transported in containers, but in most cases it is transported in bags. So when loading, accidents sometimes occur. In order to eliminate the above problems, a metal mesh can be installed in the hopper or in the pipe conveying activated carbon, and the foreign matter in the activated carbon bag can be eliminated by taking it out and cleaning it in time.
In many occasions where activated carbon is involved, it is necessary to pay attention to the problem that powdered activated carbon can not be fully deposited in the sedimentation tank or leaked from the sedimentation tank because of its non-caking. Because water leakage can lead to so-called black water, we need to pay full attention to it.
Because powdered activated carbon is very simple to fly. This point has been included in the precautions of activated carbon feeding equipment, so it is best to set the operating site of powdered activated carbon separately from its equipment. Once the toner comes into contact with the electrical system, there will be poor insulation. Therefore, this point should be carefully considered in the design, so that the activated carbon feeding equipment can obtain good results with confidence.
