To obtain high-quality industrial grade caustic soda,it is essential to ensure that all equipment used meets the standards and that workers can easily operate the equipment to obtain high-quality products while reducing labor.So what are the commonly used industry equipment?Many friends are not familiar with this knowledge,so let me introduce it to you.
1.Tablet alkali machine
As the main equipment for producing industrial grade caustic soda,molten caustic soda flows out of the three effect evaporator and enters the caustic soda machine.Cold water is introduced into the bucket to cool the molten alkali outside the bucket,and scraped off with a scraper to obtain the product.
2.Sugar jar
There is a sugar jar filled with a 5%sucrose solution between the double effect evaporator and the triple effect evaporator.The reason for adding sugar tanks is that this product can severely corrode equipment at high temperatures,so the alkaline solution is neutralized with sucrose solution to reduce corrosion to the equipment.

3.External condenser
The working principle of producing industrial grade caustic soda is that when the secondary steam contacts the external cooler,there is a temperature difference between the external cooler and the secondary steam.According to the principle of heat transfer,the heat of the secondary steam will be transferred to the refrigerant in the cooling pipe through an external cooler,thereby reducing the temperature of the secondary steam.When the external temperature of the cooler is lower than the dew point temperature of the secondary steam to be processed,the water vapor in the secondary steam is condensed to achieve the purpose of cooling and dehumidification.
The above are the commonly used mechanical equipment in industrial grade caustic soda production.In practical use,the division of labor is clear,and the chemical products we need can be produced through mutual cooperation.Only when we have a better understanding of the equipment can we ensure that the chemical products we produce meet our requirements,so it is necessary to master the knowledge of products and equipment.
