Precautions for use and operation of enamel electric heating reactor
Be careful when feeding. There shall be no hard objects falling into the enamel container. At the same time, empty tank heating materials and hot tank cooling materials shall be avoided as far as possible. The temperature difference in use shall not exceed the technical index of the equipment. Block materials or hard materials shall be strictly prevented from being entrained after being crushed. Try to reduce the temperature difference between the material and the tank wall, and avoid heating materials in the cold tank or adding cold materials in the hot tank;
When using jacketed equipment, slowly pressurize and heat up. The pressure of 0.1mp shall be introduced in advance and maintained for a quarter of an hour, and then the steam shall be slowly introduced to reach the operating pressure. If conditions permit, the appropriate temperature rise and fall curve can be found according to the actual situation of the unit, which is generally controlled below 3 ℃ / min. During the operation of the equipment, pay attention to the sealing of flanges, adapter plates, manholes and stuffing boxes, and take immediate measures in case of leakage;
During discharging, if the tank bottom is blocked, do not shovel with metal tools, but gently poke it with bamboo rod, plastic rod and wooden rod. When cooling is required after the reaction, cooling water must be supplied to the jacket after the temperature in the tank naturally drops to a certain extent to prevent sudden cooling. In the alternating action of acid and alkali, the service life of non alkali resistant enamel equipment is greatly shortened. Therefore, it is necessary to pay attention to the selection of enamel equipment with good alkali resistance. Acid resistant enamel shall not be used in the occasion of acid-base alternation. When discharging, if enamel debris is found, open the tank immediately for inspection, and then use it after repairing the porcelain surface.
