Chemical cleaning descaling process:
Recirculating closed-loop cleaning
Recirculating cleaning utilizes two existing parallel ash discharge pipelines to form a loop, creating a circulation system with the cleaning pump station. A certain concentration of acidic solution is added, which circulates within the ash water pipeline for cleaning. As the acid cleaning decreases to a certain level, the acidic solution is continuously replenished. 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 during shutdown and is complex, with higher costs.
Preliminary Cleaning
No two ash pipes should form a loop during cleaning; only single-pipe open circuit cleaning is allowed. The method involves connecting one end of the ash pipe to the cleaning unit, continuously preparing a certain concentration of cleaning solution in the mixing tank, and then injecting it into the ash pipe continuously or intermittently. This process requires additional cleaning equipment during shutdown, which increases costs.

Continuous cleaning without shutdown
The process involves continuously injecting a certain amount of acidic solution while the ash pipe is operating normally and not shut down. Simultaneously, a specific quantity of ash pipe operation cleaning inhibitor and pipeline descaling agent is added for open-loop cleaning. The primary function of the cleaning aid 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.
The procedure is as follows: Prior to cleaning, estimate the required acid quantity based on the total scale in the pipeline. Then, calculate the acid addition rate and the flow rate of the descaling agent and pipeline cleaning agent according to the sludge water flow and acidity. During cleaning, take a sample at the front 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.

2. High-pressure water cleaning machinery
High-pressure water jet cleaning offers advantages such as high efficiency, low cost, non-damaging to workpieces, non-polluting the environment, easy operation, and safety.
Advantages of high-pressure water technology include:
(1) Excellent Cleaning Quality: The high-pressure water jet cleaning for pipes and heat exchanger bores can thoroughly remove scale and blockages inside, revealing the metal substrate. With its immense energy and supersonic speed, the high-pressure water jet is fully capable of destroying hard scale and blockages without causing any damage to the metal.
Since the pressure of high-pressure water is less than the compressive strength grade of metal, high-pressure cleaning will not damage the base material being cleaned.
(2) Fast Cleaning Speed: Due to the combined effects of water jet scouring, splitting, shearing, and grinding, scaling can be quickly broken and removed, making the cleaning speed several to ten times faster than traditional chemical methods, sandblasting, simple mechanical, and manual methods.
Additionally, components cleaned with high-pressure water jetting do not require secondary cleaning; however, after chemical cleaning, the surface must be washed with clean water.
(3) No Environmental Pollution: As high-pressure water jet cleaning uses pure water as the medium, it does not generate a large amount of dust like sandblasting, shot blasting, or simple mechanical cleaning, which can pollute the atmosphere and harm health. It also does not produce a large amount of waste liquid like some chemical cleaning methods, which can contaminate rivers, soil, and water quality. The water jet, using pure water, is odorless, tasteless, and non-toxic. After atomization, it can also reduce the dust concentration in the work area, lowering atmospheric dust levels from 80mg/m³ with other methods to below the national safety standards. Therefore, it does not cause any pollution.
Pipe Scale
(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; mixed scale is usually a mixture of the above three types.

(2) Categorized by physical properties, there are two types: a hard scale that firmly adheres to the pot shell and pipe walls, and a loose sediment that is easy to dislodge.
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. Lime scale has a very low thermal conductivity, approximately 2 to 5 times that of ordinary steel. When lime scale accumulates on the boiler's heating surface, it significantly worsens the heat transfer efficiency, affecting the boiler's performance; it also tends to damage metal materials by localized overheating, potentially leading to pipe explosion accidents; it accelerates galvanic corrosion, causing pipeline lime scale corrosion, and speeding up the deterioration of the heating surface. Once lime scale forms, it should be promptly removed using either mechanical or chemical methods.
