Introduction to products:
The process of drying poly aluminum chloride by centrifugal sprayer is as following: mother liquor of poly aluminum chloride is atomized into minimal for fog drip by centrifugal atomizer at the top of drying tower, and then granular products can be formed after drip being dried.
Product property：
The product has the powder to be thin, the pellet even, easy to dissolve in the water, the flocculation effect is good, the purification highly effective stable, throws the increment to be few, cost low status characteristic. Suits in drinks the water purification, the city gives aspects and so on water purification for the water purification and the industry.
Main indexes of poly aluminum chloride:
The content of Al2O3: during the spray drying process, the centrifuge evenly sprays mother liquor in the drying tower. Therefore, the content of Al2O3 being stable and uniform can be easily controlled within the index range, as a result, it strengthens adsorption capacity of colloidal particles and achieves effects of coacervation and flocculation. Other drying method don? bear the above advantages.
Alkalized degree:
When implementing water treatment, alkalized degree (polymerization degree) directly influences the purification effect, so we adopt spray drying process for raising the polymerization degree of products on the basis of keeping the original activity of mother liquor, meanwhile, we are able to duly adjust the alkalized degree in conformity with different water quality. However, using tumble drying method easily damaged polymerization degree leading to small alkalized degree separation, which is only available for a few water qualities.
Water-in soluble:
we can keep solid water-in soluble m/m below 0.3%and liquid water-in soluble below 0.1% applying plate and frame filter press technology to guarantee use? pipes unobstructed and lift utilization rate of drugs, but using natural precipitation method can not realize the above purposes.
Superiority characteristics of spray drying poly aluminum chloride
Owing to spray drying products holding the following advantages: excellent stability, broad water area, quick hydrolysis speed, strong adsorption capacity, large alum, swift subsidence, low water turbidity, super dehydration, performance and etc., throwing quantities of spray drying products can be reduced under the condition of the same water quality, meanwhile, when the water quality is bad, throwing qualities of spray drying products can be decreased half comparing to tumble drying products., which not only relieve the intensity workers, but also cut down use? water rationing expenses. Beside the above mentioned, spray products which are suitable and reliable for drinking water can reduce water accident to guarantee the safety.
