Chemical Cleaning Scale Removal Process

Recirculating Closed Loop Cleaning

Recirculating cleaning utilizes two existing parallel ash removal pipelines to form a loop, creating a recirculation system with the cleaning pump station. A certain concentration of acidic solution is added, which circulates through the ash water pipes for cleaning. As the acid washing reaches 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 while the system is offline, and it is complex and costly.

Open path cleaning

No two gray pipes should form a loop during cleaning; only single-pipe open circuit cleaning is allowed. The method involves connecting one end of the gray pipe to the cleaning unit, continuously preparing a certain concentration of cleaning solution in the mixing tank, and then injecting it into the gray pipe continuously or intermittently. This process requires additional cleaning equipment during shutdown, which increases costs.

Continuous Cleaning Without Downtime

The process involves continuously injecting a specific amount of acidic solution while simultaneously adding a certain quantity of running ash pipe cleaning inhibitor and pipeline descaler. This is an open-loop cleaning method. The primary role of the cleaning aid is to facilitate the reaction between the acidic solution and the ash deposits at a certain concentration and flow rate, while also enhancing its solubility in water and reducing airlock formation, ensuring the quality of ash pipe cleaning.

Operation procedure: Before cleaning, first 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 ash-removing corrosion inhibitor and pipeline stripping agent based on the sludge flow rate and acidity. During the cleaning process, collect and test the acidity at the sampling point at the front of the ash pipe every 30 minutes, and strictly control the acidity by adjusting the flow rate of acid addition. In the later stage of cleaning, collect and test the pH value at the end of the ash pipe every 15 minutes. When the pH value reaches a certain level and remains unchanged for 30 minutes, the cleaning process can be considered complete.

2. High-pressure water cleaning machinery
High-pressure water jet cleaning offers advantages such as high efficiency, low cost, non-damaging to workpieces, environmental friendliness, ease of operation, and safety.
High-pressure water technology boasts the following advantages.

(1) Excellent Cleaning Quality - The high-pressure water jet cleaning of pipe and heat exchanger bores can thoroughly remove all scale and blockages inside, revealing the metal surface. The high-pressure water jet, with its immense energy and supersonic speed, can completely destroy hard scale and blockages without causing any damage to the metal.

High-pressure water cleaning will not damage the base material being cleaned, as the pressure is less than the compressive strength grade of the metal.

(2) Rapid Cleaning Speed: Due to the combined crushing effects of water jet scouring, wedge splitting, shearing, and grinding, scaling can be quickly broken and removed, which is several to ten times faster than traditional chemical methods, sandblasting and shot peening techniques, simple mechanical, and manual cleaning methods.

Components cleaned with high-pressure water jetting do not require secondary cleaning; however, after chemical cleaning, the surface must be washed off with clean water.

(3) No Environmental Pollution: Since 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 significant amount of waste liquid like some chemical cleaning methods, which can contaminate rivers, soil, and water quality. The water jet cleaning with pure water as the medium is odorless, tasteless, and non-toxic. After atomization, it can also reduce the dust concentration in the work area, lowering atmospheric dust from 80mg/m³ with other methods to below the national safety standards, thus causing no pollution.

3. Pipe Scale

(1) Classified by chemical composition, it can be divided into carbonate scale, sulfate scale, silicate scale, and mixed scale, among others. 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 three types mentioned above.

(2) Classified by physical properties, there are two types: scale that firmly adheres to the pot shell and tube walls, and sediment that is loosely textured and easily dislodged.
Lime scale primarily forms due to the salts of 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 less than that of ordinary steel. When lime scale accumulates on the boiler's heating surface, it significantly worsens the heat transfer efficiency and affects the boiler's performance; it can easily cause metal materials to burn due to localized overheating, potentially leading to tube explosion accidents; it also accelerates galvanic corrosion, causing pipeline lime scale corrosion and speeding up the damage to the heating surface. Once lime scale forms, it should be promptly removed using mechanical or chemical methods.
