Drying room with hot air distributed uniformly

Abstract

The invention discloses a drying room with hot air distributed uniformly. The drying room comprises a drying room body with drying hot air supplied by a heat source, and further comprises multiple airguide pipes evenly distributed in the drying room body. The air guide pipes are arranged on side faces close to the drying room body. Multiple exhaust holes are evenly distributed in the air guide pipes. The drying hot air supplied by the heat source is dispersed in the drying room body through the exhaust holes of the air guide pipes. The drying hot air is uniformly distributed in the three-dimensional space of the whole drying room body through the evenly-distributed air guide pipes and the exhaust holes of the air guide pipes, and balance and uniformity of temperature and temperature riseof all sections of the drying room body are achieved. The wind power and the wind speed are gentle, flying of dust cannot be caused, and safety of the system can be effectively improved for drying ofpyrotechnic powder materials. Better empirical effects can be achieved for the drying efficiency, the drying quality and safety.

Description

technical field [0001] The invention relates to a drying system, in particular to a drying room of the drying system. Background technique [0002] In the prior art, the air heated by the heat source enters the drying room through the air inlet, and then is discharged through the air outlet. Due to the poor air flow and uneven distribution of hot air, the drying temperature of the materials in different sections of the drying room is different, and the heat dissipation speed of the material surface is uneven. On the one hand, it leads to uneven drying rate; The rate at which moisture is removed from the surface of the material is greater than the rate at which moisture diffuses from the interior of the material to the surface of the material, making the surface of the material hard and encrusted, hindering the continued migration and diffusion of moisture inside the material. It not only drags down the drying efficiency of the whole batch of materials, but also causes the d...

Due to the poor air flow and uneven distribution of hot air, the drying temperature of the materials in different sections of the drying room is different, and the heat dissipation speed of the material surface is uneven. On the one hand, it leads to uneven drying rate; The rate at which moisture is removed from the surface of the material is greater than the rate at which moisture diffuses from the interior of the material to the surface of the material, making the surface of the material hard and crusty, hindering the continued migration and diffusion of moisture inside the material

Not only drags down the drying efficiency of the whole batch of materials, but also leads to uneven drying quality of the same batch of materials
