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 within 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 grey pipes can form a loop during cleaning; only single grey pipe open circuit cleaning is allowed. The method involves connecting one end of the grey pipe to the cleaning device, continuously preparing a specific concentration of cleaning solution in the mixture tank, and injecting it into the grey pipe continuously or intermittently. This process requires adding cleaning equipment while the system is offline, which increases costs.

Continuous cleaning without shutdown

This process involves continuously injecting a certain amount of acidic solution while running the ash delivery pipes, simultaneously introducing an ash delivery pipeline cleaning inhibitor and a pipeline cleaning descaler. It performs an open-circuit cleaning. The primary role of the cleaning aids is to facilitate the reaction between the acidic solution and ash deposits at a certain concentration and flow rate, while also increasing solubility in water, reducing the formation of air blockages, and ensuring the quality of ash pipeline cleaning.

The procedure is as follows: 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 ash removal agent and pipeline cleaner by considering the flow rate of the sludge water and the acidity. During cleaning, take a sample at the front end of the ash pipe every 30 minutes to test the acidity, and strictly control the acidity by adjusting the flow rate of acid addition. In the later stages of cleaning, take a sample at the end of the ash 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 process 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.
High-pressure water technology boasts the following advantages.

(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. The high-pressure water jet, with its immense energy and supersonic speed, is capable of completely destroying tough scale and blockages, yet it has no damaging effect on metal.

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

(2) Fast Cleaning Speed: Due to the combined crushing effects of water jet scouring, 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.

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) 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 large volume 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.

Pipe Scale

(1) Classified by chemical composition, they can be categorized into carbonate scale, sulfate scale, silicate scale, and mixed scale, etc. 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: a hard scale that firmly adheres to the pot shell and pipe walls, and a loose sediment that is easily detached.
Scale primarily forms due to the salts containing calcium and magnesium in the boiler feedwater, which precipitate and adhere to the metal surface upon heating. The thermal conductivity of scale is very low, about 2 to 5 times that of ordinary steel. The presence of scale on the boiler's heat-absorbing surface greatly impairs heat transfer efficiency, affecting the boiler's performance; it can easily lead to the deterioration of metal materials due to local overheating, even causing pipe burst accidents; it accelerates galvanic corrosion, leading to pipe scale corrosion and hastening the damage to the heat-absorbing surface. Once scale forms, it should be promptly removed using either mechanical or chemical methods.
