Product Details

The only 46000 energy-saving spray drying tower is designed and manufactured for our company, and the first dry pulverized coal combustion technology is used to reduce fuel consumption by about 30%.

1. Technical specifications: the tower body is 15 meters in diameter and 46 meters in height. The powder processing capacity is 65T/h.

2. Working materials: The air passes through the filter and the heater, enters the air distributor at the top of the drying tower, and then enters the drying chamber uniformly in a spiral shape. The liquid is pumped from the liquid tank through the filter to the centrifugal atomizer at the top of the drying tower, so that the liquid is sprayed into extremely small mist droplets, and the liquid is in parallel contact with the hot air, and the water evaporates rapidly, which is extremely short. Dry for the time being. The finished product is discharged from the drying tower and the cyclone, and the exhaust gas is discharged by the fan.

3. Technical advantages

(1.1) Drying speed is fast. After the liquid is sprayed by centrifugation, the surface area is greatly increased. In the high-temperature airflow, 95%-98% of the water can be evaporated instantaneously, and the drying time is only a few seconds.

(1.2) The parallel flow type of spray drying can make the droplets flow in the same direction as the hot air. Although the temperature of the hot air is higher, the hot air enters the drying chamber and immediately contacts the spray droplets, and the temperature of the chamber drops sharply, while the wet bulb of the material The temperature is essentially constant and therefore suitable for drying heat sensitive materials.

(1.3) Wide range of use. According to the characteristics of the material, it can be used for hot air drying, centrifugal granulation and cold air granulation. Most products with different characteristics can be produced by this machine.

(1.4) Since the drying process is completed in an instant, the particles of the finished product can basically maintain the shape of the droplets, and the production skin has good dispersibility, fluidity and solubility.

(1.5) The production process is simplified and the operation and control are convenient. Spray drying is usually used for solutions with a solid content of less than 60%. After drying, no further pulverization and screening are required, which reduces the production process and simplifies the production process. For the particle size, bulk density and moisture of the product, the operating conditions can be adjusted within a certain range, and the control and management are very convenient.

(1.6) In order to prevent the material from being contaminated and to extend the life of the equipment, all parts in contact with the material are made of stainless steel. After being sprayed, the liquid is atomized into dispersed particles, the surface area is greatly increased, and the drying process can be completed in a very short time after contact with hot air. Under normal circumstances, at 100-150 ° C, 1-3S can be steamed 95% -98% water. Since the drying process is completed in an instant, the particles of the finished product can substantially maintain a spherical shape similar to that of the droplets, thereby having good dispersibility, excellent brewing property, and high solubility.

(1.7) Using dry coal powder instead of coal slurry as fuel to make coal powder burn more fully, and avoiding the evaporation of water in the coal slurry, so that the drying speed is improved, which can save about 30% compared with the use of coal slurry fuel. Energy consumption.
