a. Glass lined reactor introduction
Glass lined reactor equipment is to line the inner surface of steel container with glass containing high silica, and then it is burnt at high temperature to firmly adhere to the metal surface. It is commonly used in petrochemical, rubber, pesticide, dye, pharmaceutical and other industries to complete sulfonation, nitration, hydrogenation, alkylation, polymerization, condensation and other processes, as well as reaction equipment for many other processes of organic dyes and intermediates.
b. Introduction to the structure of the glass lined reactor
When using the glass lined reactor, you must first have a full understanding of the equipment structure. The purpose of this is to better understand the role of each accessory in the equipment, and to better complete the equipment use and performance Play.
1. The kettle and the kettle cover are composed of stainless steel, the reactor body and the flange connection line. The kettle cover is a traditional cover plate, both of which are evenly distributed along the circumferential direction, and the main bolts and nuts are tightly connected.
2. The main seal of the reactor is a two-line seal. The remaining sealing points are sealed by the arc contact with the plane, the arc surface and the arc surface. The reactor relies on the high precision and smoothness of the contact surface to achieve a good sealing effect.
3. In the reactor, a cylindrical silicon carbide core is installed outside the reactor, and the electric furnace wire passes through the furnace core. The bottom of the furnace passes through the lower part of the furnace shell and is connected to the controller through a terminal and a rubber sheathed cable.
4. The lid of the glass lined reactor is equipped with a pressure gauge, a bursting membrane safety device, a vapor-liquid phase valve, a temperature sensor, etc., so that people can know the reaction situation in the kettle at any time, adjust the ratio of the medium in the kettle, and ensure safe operation.
5. The coupling is mainly composed of a pair of inner and outer magnetic rings with strong magnetic force and a pressure bearing sleeve. The agitator of the reactor is driven by a servo motor through a coupling, the speed of the servo motor is controlled, and the purpose of controlling the stirring speed can be achieved.
6. The upper part of the sleeve is equipped with a speed measuring coil. When the stirrer is combined with the inner magnetic ring, the induction coil generates an induced electromotive force. The electric potential corresponds to the stirring speed, and the electric potential can be transferred to the tachometer to display the stirring speed.
7. The cooling water jacket is installed between the magnetic coupling and the glass lined reactor. When the working temperature is high, the cooling water should be cooled, and the magnetic steel is too high to demagnetize.
8. The bearings are made of stainless steel or high-strength graphite bearings, with friction loss and long maintenance intervals.
The above is the structure of the glass lined reactor. By understanding its structure, you can better understand and use the equipment, and through its structure, you can also provide help for subsequent maintenance and avoid operating errors caused by unfamiliar equipment.
c. The scrap standard of glass lined reactor
Glass lined reactors are mainly used in the chemical industry. Because of the chemicals they contain, the quality of the equipment is very important. The equipment has a certain period of use during use. Once the equipment reaches the scrap standard , Then it cannot be refurbished.
1. During the hydraulic test, the glass lined reactor has obvious deformation or the residual deformation exceeds the specified value.
2. The local corrosion of the wall thickness of the kettle body exceeds the smaller value specified in the design, and the corrosion area is greater than 20% of the total area.
3. The uniform corrosion of the wall thickness of the glass lined reactor exceeds the smaller value specified in the design.
4. Defects exceeding the standard (such as: serious structural defects endangering safe operation, unqualified welds, severe incomplete penetration, cracks, etc.) and cannot be repaired.
5. When there are cracks in the kettle body or weld that cannot be repaired due to alkali brittleness or severe intergranular corrosion.
When we use the glass lined reactor, we must always pay attention to the use of the equipment, and ensure its material, durability, service life and other aspects of performance. If it cannot be used in refurbishment, it must be carried out in time. Replacement to ensure the safety of equipment and operation and avoid dangerous accidents.
