Do you have any suggestions for the maintenance of enamel glass disc condensers?

With the rapid development of the chemical industry, the maintenance of enamel glass disc condensers, as key equipment, is increasingly receiving widespread attention from the industry. The proposal of professional maintenance recommendations is particularly important to ensure that such equipment maintains high efficiency and stability during operation. Here are some professional suggestions:

1. Regular inspection

1. Sealing performance inspection: The sealing performance of the enamel glass disc condenser should be regularly checked to ensure that there is no leakage at all connection parts. If aging or damage is found in the sealing gasket, it should be replaced in a timely manner to avoid medium leakage affecting equipment performance and working environment.

2. Inspection of enamel layer: Use a porcelain layer thickness gauge to regularly check the thickness of the enamel layer, and the position of each inspection remains unchanged. At the same time, visually inspect the enamel layer for any signs of erosion, impact, or porcelain explosion. During the parking inspection, it is required that the inspectors do not bring any hard objects into the inner cylinder of the equipment, and conduct a detailed inspection of the enamel coating and various parts of the mixer.

2. Cleaning and maintenance

1. Internal cleaning: The interior of the enamel glass disc condenser should be kept clean, and the scale and impurities in the condenser fins and pipes should be regularly cleaned to improve heat transfer efficiency and extend the service life of the equipment. When cleaning, metal tools should not be used to avoid damaging the enamel layer.

2. Cooling water management: Pay attention to checking the quality and flow rate of the cooling water to ensure that it can fully remove heat and avoid equipment overheating. If the cooling water is found to be turbid or the flow rate is insufficient, it should be dealt with in a timely manner to avoid affecting the condensation effect of the equipment.

3. Operation precautions

1. Avoid excessive temperature difference: It is advisable to avoid heating materials during cold tank or adding cold materials during hot tank to prevent the glass lining layer from bursting due to excessive temperature difference. When operating the jacket equipment, pressure and temperature should be gradually increased.
2. Prevention of medium corrosion: It is strictly prohibited for acid solution to enter the jacket to prevent hydrogen absorption reaction of the enamel layer metal, which may cause phosphorus explosion of the enamel layer. At the same time, avoid direct contact of highly corrosive media with the enamel glass surface. When adding materials, try to use a feeding tube to directly add them to the reaction tank, so that the materials can be quickly diluted and stirred to reduce corrosion to the equipment.

3. Proper operation of feeding: It is strictly prohibited to use manholes as solid material feeding holes. Manhole is a passage designed for maintenance and inspection personnel to enter and exit equipment, which is in a closed state for a long time. When adding materials, if the discharge valve or discharge pipe is blocked, gently poke it open with non-metallic tools without touching or tapping.

4. Discontinuation and rust prevention

When the equipment is not in use for a long time, rust and corrosion prevention measures should be taken. Clean and blow dry the inside of the enamel glass disc condenser to prevent residual media from corroding the equipment. At the same time, the exposed metal surface of the glass lined equipment substrate should also be treated with anti-corrosion measures to prevent corrosive gases in the factory air from condensing onto the equipment surface and corroding the substrate metal.

5. Inspection cycle control

Strictly control the inspection cycle of the enamel glass disc condenser, and it is recommended to shorten the inspection cycle to one to two years in order to timely detect and deal with potential problems.
In summary, the maintenance of enamel glass disc condensers involves multiple aspects, including regular inspections, cleaning and maintenance, correct operation, shutdown for rust prevention, and control of inspection cycles. Only by doing these tasks well can we ensure the long-term stable operation of the equipment and extend its service life.
