Chemical cleaning and scaling removal process:
Recirculating closed-loop cleaning
Recirculating cleaning utilizes two existing parallel deslagging pipelines to form a loop, creating a circulating system with the cleaning pump station. A solution of a certain concentration of acidity is added, which circulates within the sludge water pipeline for cleaning. As the acid cleaning 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 recirculating loop for cleaning. This process must be carried out when the system is shut down, and it is complex and costly.

Open Channel Cleaning
No two grey pipes can form a loop during cleaning; only single grey pipe open-loop cleaning is allowed. The method involves connecting one end of the grey pipe to the cleaning unit, continuously preparing a certain concentration of cleaning solution in the dosing tank, and then injecting it into the grey pipe continuously or intermittently. This process requires additional cleaning equipment during shutdown, leading to higher costs.
Continuous cleaning without downtime
The process involves continuously injecting a specific amount of acidic solution while also introducing a certain quantity of slurry pipeline cleaning inhibitor and pipeline descaler. This is done for open circuit cleaning. The main function of the cleaning aids is to facilitate the reaction between the acidic solution and scale in a solution with specific concentration and flow rate, while also enhancing its solubility in water, reducing air blockage, and ensuring the quality of slurry pipeline cleaning.
The procedure is: Before cleaning, estimate the required acid quantity based on the total scale in the pipeline, then calculate the acid addition rate and sludge transport pipeline's cleaning inhibitor and pipeline descaler injection speed based on the grey water flow rate and acidity. During cleaning, collect and test the acidity at the sampling point at the front end of the grey pipeline every 30 minutes, and strictly control the acidity by adjusting the acid flow rate. In the later stage of cleaning, test the pH value at the end of the grey pipeline every 15 minutes. When the pH value reaches a certain level and remains unchanged for 30 minutes, the cleaning can be considered 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 protection, ease of operation, and safety.
Advantages of high-pressure water technology include:
(1) Excellent Cleaning Quality: High-pressure water jet cleaning of pipes and the internal cavities of heat exchangers can completely remove scale and obstructions inside, revealing the metal surface. The high-pressure water jet, with its immense energy and supersonic speed, is capable of destroying hard scale and obstructions 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 being cleaned.

(2) Fast Cleaning Speed - Due to the combined actions of jet washing, wedging, shearing, and grinding, scaling can be quickly broken and removed, making the cleaning process several to ten times faster than traditional chemical methods, sandblasting, simple mechanical, and manual methods.
Components cleaned with high-pressure water jetting do not require secondary cleaning; however, after chemical cleaning, the surface chemicals must be rinsed off with clean water.

(3) No Environmental Pollution: Since high-pressure water jet cleaning uses pure water as the medium, it does not generate large amounts of dust like sandblasting, shot blasting, or simple mechanical cleaning, which can pollute the atmosphere and harm health. Nor does it 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, the emitted jet 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.

Pipe Scale
(1) Categorized 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 three types mentioned above.
(2) Categorized by physical properties, there are two types: scale that is firmly adhered to the pot shell and tube walls, and sediment that is loosely textured and easily detached.
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, around 2 to 5 times that of ordinary steel. When lime scale accumulates on the boiler's heating surface, it severely impairs heat transfer efficiency and affects the boiler's performance; it can also cause metal materials to burn out due to localized overheating, potentially leading to pipe explosion accidents; it accelerates galvanic corrosion, causing pipeline lime scale corrosion, and hastens the damage to the heating surface. Once lime scale forms, it should be removed promptly using mechanical or chemical methods.
