Chemical Cleaning Scale Removal Process

Recirculating Closed Circuit Cleaning

Recirculating cleaning utilizes two existing parallel ash removal pipelines to form a loop, creating a circulation system with the cleaning pump station. A solution of a certain concentration is added, which circulates through the ash water pipes for cleaning. As the acid washing reduces to a certain level, the solution is continuously replenished with acid. 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 during shutdown and is complex, with higher costs.

Open Channel Cleaning

No two gray pipes can form a loop during cleaning; only a single gray pipe can be used for open-loop cleaning. The method involves connecting one end of the gray pipe to the cleaning unit and continuously preparing a specific concentration of cleaning solution in the blending tank, then injecting it into the gray pipe continuously or intermittently. This process requires additional cleaning equipment during shutdown, resulting in higher costs.

Continuous cleaning without shutdown

The process involves continuously injecting a certain amount of acidic solution while the ash pipe is operating normally without interruption, simultaneously adding a specific quantity of ash-pipe running cleaning inhibitor and pipeline cleaning descaler for open-circuit cleaning. The primary function of the cleaning aids is to promote the reaction between the acidic solution and the ash deposits at a certain concentration and flow rate, while also enhancing their solubility in water and reducing the formation of air blockages, ensuring the quality of ash-pipe cleaning.

The procedure is as follows: 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 of the descaling agent and pipeline cleaner based on the sludge water flow rate and acidity. During cleaning, take a sample 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, take a sample 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 jetting for cleaning boasts advantages such as high efficiency, low cost, non-damaging to workpieces, non-polluting the environment, ease of operation, and safety.
The high-pressure water technology offers the following advantages.

(1) Excellent cleaning quality: The high-pressure water jet cleaning of pipeline and heat exchanger bores can completely remove scale and blockages inside, revealing the metal surface. With its immense energy and supersonic movement, the high-pressure water jet is fully capable of destroying tough scale and blockages 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 effects of jet washing, wedge splitting, shearing, and grinding, scale 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.

Parts cleaned with high-pressure water jet do not require secondary cleaning; however, after chemical cleaning, the surface chemicals must be rinsed off with clear 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 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.

Pipe Scale

(1) Categorized by chemical composition, they include 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 typically a mixture of the aforementioned three types of scales.

(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 detachable.
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, approximately 2 to 5 times that of ordinary steel. When lime scale forms 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, even leading to pipe 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.
