Pure caustic soda chemical hollow paddle dryer

  Project description:
  Pure caustic soda, scientific name sodium carbonate, also known as soda, alkaline ash, an important chemical raw materials, soda ash industry's main products. Rubber industry with its alum, H pore agent with the role of uniform hair for rubber, sponge production. The metallurgical industry is used as a flux for casting ingots. The machinery industry is used as a molding aid for cast steel (sand) sand type. Printing and dyeing industry for dyeing printing fixing agent, acid and alkali buffer, fabric dyeing and finishing of the post-treatment agent. The pharmaceutical industry is used as raw material for antacids.

  

  First, Pure caustic soda chemical hollow paddle dryer overview:
 

  There are wedge-shaped hollow paddles in hollow axis,and heat medium is from-40℃ to 320℃, the heat medium is steam or hot air or heat conduction oil and so on.The heat medium (such as steam or thermal oil) will flow into chamber jacket and hollow mixing axis through rotary join. Hollow mixing axis has different inner structures according to different types of heat medium, which will ensure of best heat transfer efficient.


  At the same time of the heating of the pulp and jacket, the upper part of the outlet at the same time through the heated dry air after further drying, which greatly increased the drying strength of the device. Evaporation of water from the exhaust out of the dryer, filtered through the bag filter, the powder will be recovered after drying, the wet air from the dust after the exhaust fan exhausts to outdoors.


  Second, Pure caustic soda chemical hollow paddle dryer characteristics:
  

  1. Low energy consumption, as the heat flow is indirect, there is no large volume of sweep gas flow through the unit, which will carry heat away from dryer.Take slurry as example, heat requirement maybe as low as 1.2kg of steam/kg for evaporating 1kg water in hollow paddle dryer.
  

  2. Paddle dryer system low cost: the unit effective volume has a huge heat transfer surface, to shorten the processing time, equipment size smaller. It greatly reduces the construction area and building space.
  

  3. Environmental pollution is small: do not use the air wich carries dust material. Material solvent evaporation is very small, easy to handle. For the pollution of the material or the need to recover the solvent conditions, can be used closed circuit.

  4. Low operating costs: the device normal operation, only 1 person / day. Low-speed mixing and reasonable structure. Wear rate is very low, maintenance costs are very low.

  5. Stable operating continuously: Because of the special compression and inflation of agitation function of paddle dryer, the material grains touch the heat-transfer area thoroughly. Within the axis direction, the temperature, moisture, mixture and grades of the materials is very small so as to guarantee the stability of whole process.
