Chemical Cleaning and Scaling Removal Process

Recirculating closed-loop cleaning

Recirculating cleaning utilizes two existing parallel ash pipeline sections to form a loop, creating a recirculation system with the cleaning pump station. A solution of a certain concentration is added, and it circulates within the ash water pipeline for cleaning. Additionally, as the acid washing process reaches a certain point, acid is continuously replenished. 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 when the system is offline, and it is complex and costly.

Open Channel Cleaning

No two ash pipes can form a loop during cleaning; only a single ash pipe can be used for open circuit cleaning. The method involves connecting one end of the ash pipe to the cleaning unit, continuously preparing a specific concentration of cleaning solution in the liquid preparation tank, and then injecting it into the ash pipe continuously or intermittently. This process requires the addition of cleaning equipment during shutdown, which increases costs.

Continuous cleaning without shutdown

The process involves continuously injecting a certain amount of acidic solution while operating the ash conveying pipeline, simultaneously adding a specific quantity of ash conveying pipeline cleaning inhibitor and pipeline cleaning descaler for open-loop cleaning. The primary function of the cleaning aids is to promote the reaction between the acidic solution and the ash scale at a certain concentration and flow rate, while also enhancing its solubility in water, reducing the occurrence of air blockages, and ensuring the quality of ash pipeline cleaning.

The procedure is: 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 sludge removal agent and pipeline cleaning agent based on the sludge 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 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 friendliness, ease of operation, and safety.
Advantages of high-pressure water technology include:

(1) Excellent Cleaning Quality - The high-pressure water jet cleaning of pipe 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, can completely destroy hard 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 material being cleaned.

(2) Rapid Cleaning Speed: Due to the combined crushing effects of water jet flushing, wedging, shearing, and abrasion, scaling can be quickly broken and removed, several to tens of times faster than traditional chemical methods, sandblasting, ball peening, 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 must be rinsed with clean water.

(3) No Environmental Pollution: As high-pressure water jet cleaning uses pure water as the medium, it does not produce 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 generate a significant amount of waste liquid like some chemical cleaning methods, which can contaminate rivers, soil, and water quality. The water jet cleaning using pure water is odorless, tasteless, and non-toxic. After atomizing the spray, 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. Therefore, it does not cause any pollution.

Pipe Scale

(1) Categorized by chemical composition, it includes carbonate scale, sulfate scale, silicate scale, and mixed scale, among others. 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 aforementioned three types.
Scale Inhibitor Manufacturer Shandong Binzhou Boxing

(2) Classified by physical properties, there are two types: scale that firmly adheres to the pot shell and pipe walls, and sediment that is loosely textured and easily detachable.
Lime scale primarily forms due to the salts of calcium and magnesium present in the boiler feed water, which precipitate and adhere to the metal surface upon heating. Lime scale has a very low thermal conductivity, approximately 2-5 times that of ordinary steel. When lime scale accumulates 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, potentially leading to pipe explosion accidents; it also accelerates galvanic corrosion, causing pipeline lime scale corrosion and speeding up the deterioration of the heating surface. Once lime scale forms, it should be promptly removed using mechanical or chemical methods.
