Coal dust pulse air dryer

  Project description:
  Pulverized coal, particle characteristics Pulverized coal is composed of different sizes, irregular shape of the powder composition, the density of coal pulverized coal density is small, the pulverized coal has a very small particles, the unit quality of coal has a larger of the surface area, the surface can absorb a lot of air, so that it has mobility. This feature makes the pulverized coal easy to transport, the disadvantage is easy to form pulverized coal flow, the equipment is not tight when easy to leak powder.
  Jiangsu Jianda Dry Engineering Co., Ltd. produces coal powder dryer, can effectively help you to dry the coal powder.

  First, the principle of coal dust pulse air dryer:
  The pulse air dryer is a quick removal of water (mainly surface water) from small particles and powdered wet materials that are easily dehydrated. Pulse air drying, due to material retention time is very short, so that the quality of the product after drying is the best guarantee. The use of pulsed air flow tube as augmented heat transfer structure, by changing the material and the relative speed between the heat medium to strengthen the heat and mass transfer process to achieve the rapid removal of water material.

  Second, the characteristics of coal dust pulse air dryer:
  1. Dry strength is large, as the airflow speed is high, the particles are well dispersed in the gas phase, and the total surface area of the particles can be used as the dry effective area, so the effective area of the drying is greatly increased. In the same way, due to the dispersion of the drying and vibration, so that the gasification surface constantly updated, therefore, dry heat transfer, mass transfer process is strengthed.
  2. Drying time is short, gas-solid two-phase time is very short, drying time 0.5-2 seconds, up to 5 seconds. The thermal denaturation of the material is generally a function of temperature and time, and therefore the quality of the heat-sensitive or low-melting material does not cause overheating or decomposition.
  3. High thermal efficiency, the gluten dryer uses gas-solid phase co-operation, and in the surface stage, the material is always in the temperature of the wet ring with the temperature of the gas is generally not more than 60-65 ℃, in the dry end of the material temperature rise stage, the gas temperature has been greatly reduced, the product temperature does not exceed 70-90 ℃, therefore, you can use high temperature air.
  4. Handling capacity is large. A diameter of 0.7m long 10-15m air drying tube, each hour can handle 25 tons of coal or 15 tons of ammonium sulfate.
  5. The equipment is simple, Gluten dryer equipment is simple, small footprint, save investment. Compared with the rotary dryer, the area is reduced by 60%, and the province is about 80%. Crushing, screening, transportation and other unit process joint operation, not only the process is simplified, and easy to operate automatically control.
  6. Wide range of applications. It can be used for a variety of powder granular materials.
