AI Technical Summary
Technical Problem
In existing technologies, the temperature difference between the slurry and the hot air is too large, resulting in problems such as low drying efficiency and high moisture content in the powder.
Method used
Two sets of heat exchange pipelines are added to the slurry storage equipment. The hot air in the spray drying tower and the cooling water of the sintering equipment are used to preheat the slurry. The slurry is heated through the first heat exchange pipeline and the second heat exchange pipeline respectively, raising the slurry temperature to 85℃±5℃.
Benefits of technology
It improves drying efficiency, reduces the moisture content of powder, enables resource recycling, reduces production costs, and enhances production efficiency.

Abstract
The utility model belongs to the technical field of heat supply equipment, and discloses a double-channel slurry preheating system which comprises slurry storage equipment, a spray drying tower and air draft equipment, and a suction port of the air draft equipment extends into the spray drying tower. The slurry storage equipment comprises a body, a containing cavity formed in the body and used for containing slurry, a discharging port formed in the body and communicated with the containing cavity and a first heat exchange pipeline arranged in the containing cavity, the input end of the first heat exchange pipeline is connected with an air outlet of the air draft equipment, and the discharging port is connected with a spray gun of the spray drying tower. The first heat exchange pipeline and the second heat exchange pipeline are used for heating slurry at the same time, the slurry can be rapidly and effectively preheated, the temperature of the slurry can reach 85 DEG C + / -5 DEG C, hot air in the spray drying tower can rapidly dry the slurry, and the drying efficiency of the spray drying tower is greatly improved; and meanwhile, the water content of the powder can meet the required requirement.
