Chemical Cleaning Scale Removal Process
Recirculating cleaning utilizes two existing parallel ash piping lines 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 ash water pipes for cleaning. As the acid washing decreases to a certain level, the solution is continuously replenished with acid. For short-distance single ash water pipelines, if conditions permit, a temporary pipeline can be laid to form a recirculation loop for cleaning. This process must be carried out while the system is shut down, and it is complex and costly.
No two ash pipes should form a loop during cleaning; only a single ash pipe should 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 blending tank, and then injecting it into the ash pipe continuously or intermittently. This process requires additional cleaning equipment during shutdown, resulting in higher costs.
This process involves continuously injecting a certain amount of acidic solution while operating the ash conveying pipes, simultaneously introducing a specific quantity of ash conveying pipe 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 the ash scale at a certain concentration and flow rate, while also increasing its solubility in water and reducing the formation of air blockages, ensuring the quality of ash pipe cleaning.
High-pressure water jet cleaning offers advantages such as high efficiency, low cost, non-damaging to workpieces, non-polluting the environment, ease of operation, and safety.
High-pressure water technology boasts the following advantages.
Since the pressure of the high-pressure water is less than the compressive strength grade of metal, high-pressure cleaning will not damage the base material being cleaned.
Additionally, parts cleaned with high-pressure water jetting do not require secondary cleaning.
(1) Classified by chemical composition, they include carbonate scale, sulfate scale, silicate scale, and mixed scale. The main components of carbonate scale are calcium carbonate and magnesium carbonate; the main components of sulfate scale and silicate scale are calcium sulfate and silicate compounds, respectively.
Lime scale primarily forms due to the salts like calcium and magnesium present in the boiler feed water, which precipitate and adhere to the metal surface upon heating. The thermal conductivity of lime scale
Corrosion intensifies, leading to scale corrosion in pipelines and accelerates the damage to heated surfaces. Once scale forms, it should be promptly removed using mechanical or chemical methods. Effective ways to prevent or slow down scale formation include strictly controlling the quality of incoming water and using appropriate water treatment agents and effluent management.
