Enamel reaction kettle separate type and closed type two structure, open for the body cover separation, in the middle with the cushion and clip is connected, is generally the volume in 5000L the following; closed type for body cover one, the general volume in 5000L above. These two structures have their own advantages, convenient disassembly of the open, if there is a problem with a nozzle on the tank cover, easy to remove the individual repair, and closed sealing performance is better. Generally speaking, there is an open structure flat welding flange connection peace cover type two.
Glass lined reactor is widely used in chemical, petroleum, medicine, pesticide, food industry etc.. In order to ensure the normal use of glass lined reactor, the main performance and installation, use of notes are as follows:
2, acid resistance: the organic acid, inorganic acid, organic solvents have better corrosion resistance. If the glass specimen is placed in the 20%HCI solution in boiling 48h, the corrosion rate of 0.9g/m2.d (quality indexes of 1.0g/m2.d).
3, alkali resistant: glass lining for alkaline solution corrosion of acid solution difference. But the glass sample in 1N NaOH solution corrosion test, temperature 80 48h. The corrosion rate was 6.76g/m2.d (7.0g/m2.d).
4, the operating temperature: glass lined equipment heating and cooling, should be slow. Glass lined equipment use temperature is 0 to 200 DEG C, temperature more than 200 DEG C for acute degeneration.
5, thickness of porcelain porcelain thickness: 0.8-2.0mm glass equipment, porcelain thickness 0.6-1.8mm glass lined equipment accessories.
6, pressure electric: glass lined with good insulation, when the glass lined in the specified thickness with 20kV high frequency spark check porcelain layer, high-frequency electric spark can breakdown of porcelain layer.
7, impact resistance: the glass layer of the internal stress is smaller, the better the elasticity, the higher the hardness, the higher the flexural compressive strength, the impact resistance is better. The glass layer is in the specified thickness, with a diameter of 30mm, the weight of 112G steel ball impact, the impact power of 282 x 10-3J.
