Chemical Cleaning Scale 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. It involves adding a certain concentration of acidic solution, which circulates within the sludge water pipeline for cleaning. Additionally, as the acid cleaning reaches a certain level, more acidic solution is continuously added. For short-distance single sludge water pipelines, if conditions permit, a temporary pipeline can be laid to create a circulating loop for cleaning. This process must be carried out while the system is shut down, and it is complex and costly.

Open channel cleaning
During cleaning, two grey pipes cannot form a loop; only a single grey pipe can be used for open-path cleaning. The method involves connecting one end of the grey pipe to the cleaning device, continuously preparing a specific concentration of cleaning solution in the fluid tank, and then injecting it into the grey pipe continuously or intermittently. This process requires additional cleaning equipment during shutdown, resulting in higher costs.
Continuous Operation Cleaning
This process involves continuously injecting a certain amount of acidic solution while operating under normal ash transportation conditions, simultaneously adding a specific quantity of ash-transporting tube cleaning inhibitor and pipeline descaling agent, and performing open-circuit cleaning. The main 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: Prior to 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 of the sludge pipeline cleaning inhibitor and pipeline cleaning stripping agent based on the gray water flow rate and acidity. During cleaning, collect samples at the front sampling point of the gray pipe every 30 minutes to test the acidity, and strictly control the acidity by adjusting the acid flow rate. In the later stage of cleaning, collect samples at the end of the gray 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 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.
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 all scale and blockages inside, revealing the metal substrate. With immense energy and moving at supersonic speeds, the high-pressure water jet is fully capable of destroying hard scale and blockages, yet it has no destructive effect on 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) Rapid Cleaning Speed: Due to the combined abrasive actions of water jet washing, wedge splitting, shearing, and grinding, scale 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 jet do not require secondary cleaning; however, after chemical cleaning, the surface chemical agents need to 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 large volume of waste liquid like some chemical cleaning methods, which can contaminate rivers, soil, and water quality. The water jet cleaning using clean 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.

3. 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; sulfate scale and silicate scale are primarily composed of calcium sulfate and silicate compounds, respectively; mixed scale is usually a mixture of the above three types..jpg)
(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.
Scale is primarily formed when salts such as calcium and magnesium in the boiler feedwater precipitate and adhere to the metal surface upon heating. The thermal conductivity of scale is very low, around 2 to 5 times that of ordinary steel. Scale on the boiler heating surface greatly deteriorates heat transfer efficiency, affecting the boiler's performance; it can easily cause metal materials to burn out due to local overheating, even leading to pipe explosion accidents; it also accelerates galvanic corrosion, causing pipeline scale corrosion and speeding up the damage to the heating surface. Once scale forms, it should be promptly removed using mechanical or chemical methods.
