Improve the stability of glass-lined reactor production

The glass-lined reactor replaces the traditional jacketed wall with a single-layered kettle wall, so that the reaction vessel does not withstand or only withstands a small external pressure, thus freeing the wall of the conventional external pressure vessel due to the increase in volume. The limitation of factors such as excessive thickness and poor heat transfer makes the volume of the reactor reachable. 30m 3, even larger, which greatly improved the capacity of the single kettle.

High heat transfer coefficient The heating and cooling of the reaction medium are both built-in plate heat exchangers, the heat transfer coefficient is 40% higher than the traditional coil heat exchanger, and the plate heat exchanger structure is compact, which is beneficial to the larger volume. A sufficient heating and cooling area is arranged in the reaction vessel to make the synthesis reaction process of the resin more uniform and stable. The glass-lined reactor is easy to repair. Since the built-in plate heat exchanger is detachable, it is easy to clean and repair, which helps to reduce operational failure and improve production stability.

In summary, the large-capacity reaction kettle has the advantages of large production capacity, good heat transfer effect, and easy maintenance. It can reduce the number of equipment in production practice, save plant investment, reduce operators, and reduce production costs. Therefore, large-capacity reactors are increasingly being used in the production of wood-based panel adhesives. The anti-corrosion effect of bismuth glass on alkaline solution is worse than that of acid solution. However, the glass samples of our factory were placed in 1N sodium hydroxide solution for corrosion, test temperature 80 ° C Time 48h. Corrosion rate is 6.76g /m2.d (Excellent product indicator is 7.0g /m2.d).

Porcelain layer thickness of glass equipment 0.8 -2.0mm , the thickness of the porcelain layer of the glass-lined equipment attachment is 0.6 -1.8mm . The bismuth glass has good insulation. When the enamel glass is inspected with a 20KV high-frequency electric spark in a specified thickness, the high-frequency electric spark cannot penetrate the porcelain layer. Because the enamel reactor is in high temperature, high pressure, corrosive medium for a long time, and is affected by quenching and rapid heat during operation, the enamel reactor is prone to blasting.

After the porcelain explosion, the metal matrix is ​​exposed. Due to the action of corrosive medium, the metal matrix is ​​corroded. In many large chemical companies, the production is continuous, and a large reactor is used, and a reactor has a porcelain explosion phenomenon. Even if the area is very small, it may affect the quality of the entire factory and normal production, so the repair of the enamel reactor has attracted wide attention. If you can find a simple, economical and reliable repair method, it has good economic benefits for the enterprise.
