Chemical Cleaning Scale Removal Process
Recirculating Closed Circuit Cleaning
Recirculating cleaning utilizes two existing parallel deslagging pipelines to form a loop, creating a recirculation system with the cleaning pump station. A solution of a certain concentration is added, which circulates through the sludge water pipeline for cleaning. As the acid washing decreases to a certain level, the solution is continuously replenished. For short-distance single sludge water pipelines, if conditions permit, a temporary pipeline can be laid to form a recirculation loop for cleaning. This process must be carried out during shutdown and is complex and costly.

Pilot cleaning
No two ash pipes can form a loop during cleaning; only a single ash pipe can be used for open-circuit cleaning. The method involves connecting one end of the ash pipe to the cleaning unit, continuously preparing a specific concentration of cleaning solution in the mixture tank, and then injecting it into the ash pipe continuously or intermittently. This process requires the addition of cleaning equipment during shutdown, which increases costs.

Continuous cleaning without shutdown
The process involves continuously injecting a certain amount of acidic solution while running the ash conveying pipe, simultaneously adding a specific quantity of ash conveying pipe running cleaning inhibitor and pipeline cleaning descaler for open-circuit cleaning. The primary function of the cleaning aids is to promote the reaction between the acidic solution and ash scale at a certain concentration and flow rate, while also increasing its solubility in water, reducing the occurrence of gas blockage, and ensuring the quality of ash pipe cleaning.
Operation method: Before cleaning, first estimate the required acid amount based on the total scale in the pipeline. Then, calculate the acid addition rate and the flow rate for adding sludge washing and pipeline descaler based on the grey water flow rate and acidity. During cleaning, take a sample at the front end of the sludge pipe every 30 minutes to test the acidity and strictly control it by adjusting the acid flow rate. In the later stage of cleaning, take a sample at the end of the sludge pipe every 15 minutes to test the pH value. When the pH value reaches a certain level and remains unchanged for 30 minutes, the cleaning can be deemed complete.
