Glass lined vacuum dryer breakage causes and repair methods

Abstract:

Glass lined reactor in the chemical production industry is very important equipment, when it is in use will inevitably occur some damage, this time the staff should be timely repair, then the following we give you the reasons for the breakage of the glass lined reactor and repair methods a, the reasons for the breakage of the 1, the substrate material is not qualified. 2, the processing of the stress damage. 3, the lining of the burnt quality of the poor 4, the thermal stress damage. 5, the damage of the thermal stress. 6, the damage to the glass lined reactor. 7, the damage to the glass lined reactor. 8, the damage of the glass lined reactor. 9, the damage to the glass lined reactor. …

Glass lined vacuum dryer in the chemical production industry is very important equipment, when it is used in the time will inevitably occur some damage, this time the staff should be timely repair, then below we give you the reasons for the breakage of glass lined vacuum dryer and repair methods:

I. Reasons for breakage

  1. Substandard base material.
  2. Processing stress damage.
  3. Poor quality of enameling.
  4. Heat stress damage.
  5. Mechanical damage.
  6. Hydrogen precipitation corrosion.
  7. Static electricity puncture.

II. Repair method
(1) recalcined glass lining:
  1. This is the traditional method of equipment repair, but also can solve the problem. The general repair period is about 30 days, relatively long, and the cost is very high, so the repair process is more complex.
  2. Before recalcining the glass lining for the vacuum dryer, it is necessary to remove the previous glass lining and smooth the inner wall, so the thickness of the steel plate will be thinner, and this method can only be used once or twice.
  3. At the same time, the equipment should be returned to the manufacturer for processing, so the production line needs to be stopped, which will cause a lot of losses.
(2) Glass lining repair agent:
  1. In contrast to this method is more economical and practical, is the use of a variety of glass lining repair agent to repair the damaged parts of the glass lining dryer.
  2. When operating only need to remove the problematic parts, around the grinding flat and smooth, so as not to repair incomplete.
  3. And then use the glass lining repair agent to fill or use polymer materials to complete the glass lining equipment, such as de-enameling, perforation, corrosion and other problems of the parts.
  4. The whole repair period only takes about one day, and the cost cost is according to the size of the traumatic surface, because of the small workload, so the vacuum dryer can be restarted production very soon, it is currently many chemical enterprises will take the repair method.
  5. We need to remind you that, with this method to repair the dryer may soon reoccur, or to solve the fundamental problem.
  Glass lined vacuum dryer in the working process, will come into contact with some chemical materials, many of which are corrosive, which is the main reason why the equipment will be damaged, our staff to do is to repair in a timely manner, to solve the problem from the root.
