Device for drying complex solution

Abstract

The invention discloses a device for drying a complex solution. The device comprises a drying bed tank body, wherein the drying bed tank body is vertically arranged, the bottom of the drying bed tankbody is provided with an air distribution plate, the air distribution plate is provided with air distribution holes, the lower portion of the drying bed tank body is horizontally provided with a material distributing pipe, the material distributing pipe is provided with spray holes, the upper portion of the drying bed tank body is provided with a carrier intercepting net, an inert carrier is placed between the carrier intercepting net and the air distribution plate, the top of the drying bed tank body is provided with a water-steam separating plate, and a material delivery pipe is arranged onthe side face of the portion, between the water-steam separating plate and the carrier intercepting net, of the tank body. The device utilizes moving collision of the inert carrier to prevent the spray holes from being blocked by formed scale, is provided with the water-steam separating plate to separate steam, and ensures a drying effect. The device is not prone to blockage, is low in fault rateduring operation, efficient, reliable, good in drying effect and easy to maintain.

Description

technical field [0001] The invention relates to the field of solution drying equipment, in particular to an equipment for complex solution drying. Background technique [0002] In the drying bed equipment, high-temperature hot air is usually used as the heat source to dry the water-containing material entering the bed, and then obtain dry solids. During the working process of the drying bed, the drying slurry is usually sprayed into the drying bed through the nozzle. Due to the high temperature in the bed, it is very easy to cause fouling and blockage on the nozzle equipment, resulting in a high failure rate of the equipment and a greatly reduced reliability. Now If the drying bed adopts the nozzle structure, it needs to be shut down and cleaned regularly, and the work intensity is high. [0003] Secondly, after the water in the solution evaporates into water vapor, it will be discharged together with the dry solids along with the exhaust gas, and then adsorbed in the dry s...

During the working process of the drying bed, the drying slurry is usually sprayed into the drying bed through the nozzle. Due to the high temperature in the bed, it is very easy to cause fouling and blockage on the nozzle equipment, resulting in a high failure rate of the equipment and a greatly reduced reliability. Now If the drying bed adopts the nozzle structure, it needs to be shut down and cleaned regularly, and the work intensity is high

[0003] Secondly, after the water in the solution evaporates into water vapor, it will be discharged together with the dry solids along with the exhaust gas, and then adsorbed in the dry solids in the subsequent channel, resulting in poor drying effect, and more often the dry solids need to be secondary secondary drying
