Chemical Cleaning Scale Removal Process

Recirculating closed-loop cleaning

Recirculating cleaning utilizes two existing parallel deslagging 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 sludge water pipes for cleaning. As the acid washing reaches a certain level, the acidic 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 while the system is shut down, and it is complex and costly.

Open channel cleaning

No two ash pipes can 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 liquid mixing tank, and then continuously or intermittently injecting it into the ash pipe. This process requires adding cleaning equipment during shutdown, which increases costs.

Continuous operation cleaning

The process involves continuously injecting a certain amount of acidic solution while operating under normal ash transport conditions in the ash pipe, simultaneously adding a certain quantity of ash pipe running cleaning inhibitor and pipeline descaling agent, and performing 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, reducing the occurrence of air blockage, and ensuring the quality of ash pipe cleaning.

Operation procedure: 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 the cleaning inhibitor and pipeline descaler according to the sludge flow rate and acidity. During cleaning, collect samples at the sampling point 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, collect samples 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 jet cleaning equipment
High-pressure water jet cleaning offers advantages such as high efficiency, low cost, non-damaging to workpieces, environmental friendliness, ease of operation, and safety.
The advantages of high-pressure water technology are as follows.

(1) Excellent Cleaning Quality: High-pressure water jet cleaning of pipeline and heat exchanger bores effectively removes all scaling and obstructions inside, revealing the metal surface. The high-pressure water jet, with its immense energy and ultra-sonic speed, can completely break down hard scaling and obstructions without damaging the metal.

Due to the pressure of high-pressure water being 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 actions of water jet abrasion, splitting, shearing, and grinding, scaling can be quickly disintegrated and removed, making the cleaning process several to ten times faster than traditional chemical methods, sandblasting, simple mechanical, and manual methods.

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

(3) Non-Environmental Pollution: Since high-pressure water jet cleaning uses clean water as the medium, it does not produce a large amount of dust like sandblasting, grit-blasting, or simple mechanical cleaning, which can pollute the atmosphere and harm health. It also does not generate a significant amount of waste liquid like some chemical cleaning methods, which can contaminate rivers, soil, and water quality. The water jet cleaning with clean 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 levels from 80mg/m³ using other methods to below the national safety standards, thus causing no pollution.

3. Pipe Scale

(1) Classified by chemical composition, they can be categorized into 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 of scales.

(2) Categorized by physical properties, there are two types: hard scale that firmly adheres to the pot shell and tube walls, and loose sediment that is easy to detach.
Lime scale primarily forms due to the salts like calcium and magnesium in the boiler feed water, which precipitate and adhere to the metal surface upon heating. Lime scale has a very low thermal conductivity, about 2 to 5 times that of ordinary steel. When lime scale accumulates on the boiler's heating surface, it significantly worsens 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.
