Flush: Before pickling, wash the Jiangmen diesel tank first, and flush the heat exchanger to ensure there are no impurities such as soil and scale inside. This can improve the pickling effect and reduce the acid consumption. Pour the cleaning fluid into the equipment and then into the heat exchanger. 2. Pickling: Submerge the heat exchanger containing the acid solution statically for 2 hours. Then continue with dynamic circulation for 3-4 hours. At the same time, perform front and replacement cleaning. After pickling, if the pH value of the acid solution is greater than 2, the acid solution can be reused. Diesel Tank Cleaning

Alkaline Wash: After acid washing is completed, mix NaOH, Na2CO3, Na3PO4, and softened water in a certain proportion. Use dynamic circulation method to wash the heat exchanger with alkali to achieve acid-base neutralization and prevent further corrosion of the heat exchanger plates. Water Wash: After the alkaline wash is completed, repeatedly rinse the heat exchanger with clean soft water to flush out any residues. The main cause of scale formation is the low solubility of calcium and magnesium salts in water. These salts share a common characteristic. Their solubility decreases with increasing water temperature, becoming incompatible salts. Diesel Tank Cleaning

Regularly inspecting the air filter and cooling fan of the variable-frequency inverter is also very necessary. For special high-cold environments, to prevent the inverter from malfunctioning due to extremely low temperatures, it is necessary to take measures such as setting up air heaters. Power abnormalities can generally be categorized into three types: phase loss, low voltage, and power outage. Sometimes, a combination of these occurs. The main causes of these abnormal phenomena are often due to transmission lines being affected by wind, snow, lightning strikes, and sometimes due to ground faults and phase-to-phase faults within the same power supply system.

Boiler Cleaning and Thermal Maintenance: Maintain a certain pressure within the hot water boiler. Approximately, ensure the boiler water temperature exceeds 100°C without nutrients. The internal pressure of the boiler can prevent external air from entering the drum. To maintain the water temperature, steam from other boilers can be used to heat the water. In cases where a single boiler lacks steam during maintenance, it can be maintained by life support within the furnace. This method is generally used for thermal standby boilers or boilers that are off for no more than a week. Diesel Tank Cleaning

Boiler cleaning with wet maintenance involves using a certain concentration of alkaline solution to come into contact with the metal surfaces inside the boiler. This forms an alkaline protective film on the metal surface to prevent corrosion.

Boiler cleaning resins contain weakly acidic groups, such as -COOH, which can dissociate into H+ ions in water, making them acidic. The remaining negatively charged groups, such as R-COO- (where R is a hydrocarbon group), can adsorb and bind with other cations in the solution, producing cationic action for boiler cleaning. The acidity of this resin is relatively weak, making it difficult to dissociate and ionize at low pH levels. Diesel tank cleaning

1. First, appoint a duty leader as the on-site overall commander, responsible for the oil tank cleaning process. 2. Organize the cleaning crew into groups with senior staff mentoring new members, clarify the support staff, and ensure assistants supervise the prevention and control measures as well as photo collection. 3. Assign a specialist to conduct risk assessments for the entire oil tank cleaning process, focusing on large diesel tank cleaning, to keep risks within the acceptable range. 4. Specify the frequency of oil tanker arrivals to ensure that one tank is used and another is received, guaranteeing oil safety. 5. Before cleaning, transfer the residual oil into the receiving tank, open the lighting and manholes of the oil tank, clean the oil storage diesel tanks, ensure adequate ventilation, and prepare cleaning supplies in advance.
