Impinging stream drying equipment for industrial applications
    A sewage sludge and industrial drying slag bad
    A large city with organic ingredients and industrial waste, can be used as a supplement fuel, thereby improving the overall thermal efficiency of the ISD device. Its waste contains up to 56% of the plant fibers. The evaporation capacity of 10000kg / h in standard Huai impinging stream drying machine, with additional dry residue combustion device, not only can reduce fuel consumption, although 2/3, but also make the product water from the dry residue burning without 30% to 10%.
    (2) drying the metal powder
    Particularly suitable for dry quartz sand, foundry sand, metal powder, a variety of polymers and with weakly bound water surface or similar materials.
    3 dried crystalline lysine
    After the separation of crystalline amino grain size of 0.2-0.25mm, and in order to meet final moisture after drying is less than 1% -1.5%, particle size less than 0.5-0.6mm. Impinging stream drying equipment consists of a central dryer and are located at the ends of the two chambers of the collision, the center dryer length 1.5m. Two pairs of rooms are hit by the cyclone and airflow out pipe and connected to the switch. Two out pipe installed inside the rejection of 1.3mm mesh grid. In the dryer that has the mass ratio of 1:1 mixture of ammonium, 2mm diameter steel ball and a diameter of 3mm aluminum beads, crystals of lysine for crushing and playing sanjie groups. In a desiccator inert particle mass concentration was maintained at 1-1.5kg/kg, two pairs of collision frequency between chambers exhumation movement 1-2 times per second, into two pairs of thermal collision chamber ends air temperature of 135 ℃. Speed ​​of 20 to 30m / s. Switch allows the collision zone between the two colliding chamber periodically move. This leads to the inert particles, and only one end by the drying of wet material continuously oscillating movement. After 4-5 oscillations, which is equivalent to 10-15s after the drying time, the material is finely ground and dried, and then was left out flow out through the mesh into the cyclone. The volume of evaporation capacity drying equipment is about 1700kg / (m3.h), air consumption (standard state) 200-250m3/kg water, hot water consumption is 3-3.6MJ/kg. This indicates impinging stream dryer significantly outperforms fluidized bed dryer, drying in the same conditions, fluidized bed dryer evaporation capacity is only 20-50k8 / (m3.h), while the drying time takes about 5 - 10min.
    4 slurry drying heat sensitive materials
Slurry suspension was used for drying and heat-sensitive materials swirl spray dryer, it is actually used as a counter-rotating pairs of impinging stream drying machine is running.
