Chemical Cleaning Scale Removal Process

Recirculating Closed Circuit 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, and it circulates within the slurry pipes for cleaning. As the acid cleaning decreases to a certain level, the acidic solution is continuously replenished. For short-distance single slurry 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-path cleaning

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

Continuous cleaning without downtime

The process involves continuously injecting a certain amount of acidic solution into the ash pipe while it is operating normally without interruption, along with a certain quantity of ash-pipe operating cleaning inhibitor and pipeline cleaning descaler. The system is flushed in an open-loop manner. The primary role of the cleaning additive is to promote the reaction between the acidic solution and the ash deposits at a specific concentration and flow rate, while also enhancing its solubility in water, reducing air blockage, and ensuring the quality of ash-pipe cleaning.

The procedure is as follows: Prior to cleaning, estimate the required acid quantity based on the total scale in the pipeline. Then, calculate the acid addition rate and the flow rate for the washing inhibitor and pipeline cleaner stripping agent according to the sludge water flow rate and acidity. During cleaning, take a sample at the front 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, test the pH value at the end of the sludge pipe every 15 minutes. 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 jet cleaning offers advantages such as high efficiency, low cost, non-damaging to workpieces, environmental friendliness, ease of operation, and safety.
The high-pressure water technology boasts the following advantages.

(1) Excellent Cleaning Quality - High-pressure water jet cleaning of pipe and heat exchanger bores can thoroughly remove scale and blockages inside, revealing the metal surface. 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 substrate being cleaned.

(2) Fast Cleaning Speed: Due to the combined actions of water jet washing, wedging, shearing, and abrasion, scaling can be quickly broken and removed, which is several to ten times faster than traditional chemical methods, sandblasting and shot blasting, 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: Since 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 with pure water as the medium is odorless, tasteless, and non-toxic. After atomization, the spray 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 include carbonate scale, sulfate scale, silicate scale, and mixed scale, among others. The primary components of carbonate scale are calcium carbonate and magnesium carbonate; sulfate scale and silicate scale are mainly composed of calcium sulfate and silicate compounds, respectively; mixed scale is typically a mixture of the aforementioned three types.

(2) Classified by physical properties, there are two types: scale that is firmly adhered to the pot shell and pipe walls, and sediment that is loosely textured and easily detachable.
Lime scale primarily forms due to the salts, such as calcium and magnesium, present in the boiler feedwater that 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 accumulates on the boiler's heating surface, it significantly deteriorates heat transfer efficiency and affects the boiler's performance; it can also easily cause metal materials to burn due to localized overheating, potentially leading to pipe explosion accidents; it accelerates galvanic corrosion, causing pipeline lime scale corrosion, and speeds up the deterioration of the heating surface. Once lime scale forms, it should be promptly removed using mechanical or chemical methods.
