Spray drying polyaluminum chloride -- Asiafloc-PAC

Spray - drying polyaluminium chloride is a new process product of polyaluminium chloride. Characteristics of spray drying polyaluminum chloride:

The characteristics of spray - dried polyaluminium chloride (PAC) depend on the operation principle of the pressure spray. The spray polyaluminium chloride is atomized into small particles when it is dried. This particle form has good application performance. Polyaluminium chloride is water soluble material, has good thermal stability and high solubility, in the process of drying, the 40-50% of aluminium chloride solution into a high pressure pump, through the pressure into the atomizer in the dryer after atomization, dispersed into tiny droplets, droplets are granular products after drying, drying and granulating completed at the same time.

Spray drying polyaluminium chloride product uses

Can adapt to the PH range of 5.0-9.0;

1, can be applied to the treatment of river water, lake water and groundwater;

2, can be used in industrial water and industrial recycling water treatment;

3, can be used in wastewater treatment;

4, can be used in coal mine scouring wastewater and porcelain industry wastewater recovery;

5, can be used in printing plant, printing and dyeing factory, tannery, brewing plant, meat processing plant, pharmaceutical factory, paper mill, coal washing, metallurgy, mining area, and the treatment of wastewater containing fluorine, oil, heavy metals;

6, can be applied to leather and cloth wrinkle prevention;

7, can be used in cement solidification and mold casting;

8, can be used in medicine, glycerin and sugar refining;

9, can be used as a good catalyst;

10, can be applied to paper adhesive. The characteristics of spray-dried PAC PAC depend on the principle of operation of the pressure spray. Aluminum chloride produced by pressure spray drying process is porous or hollow small particles, showing dustproof and smoothness. Because of its better contact with the water to be treated, its wettability and water treatment speed are stronger than other powder products. Spray production not only dries polyaluminum chloride but also reduces it to tiny particles. Polyaluminum chloride is a water-soluble substance with good thermal stability and solubility.

Application method of spray drying polyaluminium chloride

Users can determine the appropriate dosage according to different water quality and different terrain, through the test of dispensing drug concentration.

1. Liquid products can be placed directly or diluted. Solid products need to be dissolved and diluted before placing. Determine the dilution amount based on the water quality and product quantity to be treated. The dilution ratio is 2-20% for solid products and 5-50%(depending on weight) for liquid products.

2, liquid product dosage is 3-40g/ton, solid dosage is 1-15g/ton, the specific dosage is subject to flocculation test and experiment.

3. The acidity of spray polyaluminium chloride is lower than that of other inorganic flocculants.

The difference between spray polyaluminium chloride and drum polyaluminium chloride production process

Spray drying: liquid raw materials ---- pressure filtration ---- spray tower spray drying ---- finished products

Drum drying: liquid raw materials ---- placed ---- drum drying ---- finished products

Different synthesis costs:

Spray dried polyaluminum chloride products have high stability, adaptability to wide water area, fast hydrolysis speed, strong absorption, fast flocculation formation and large, low turbidity, and super dehydrating. For the same water quality, spray drying products are less than other products, especially for high pollution water quality, spray drying products only need half of drum drying products, which not only reduces labor intensity, but also reduces customer costs. In addition, too much spray drying products will not cause pollution, can avoid accidents, to ensure the quality of drinking water safety.
