Chemical cleaning descaling process:
Recirculating Closed Loop Cleaning
Recirculating cleaning utilizes two existing parallel ash piping lines to form a loop, creating a circulating 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 reaches a certain level, the solution is continuously replenished with more acid. For short-distance single ash water pipelines, if conditions permit, a temporary pipeline can be laid to form a circulating loop for cleaning. This process must be carried out during shutdown and is complex and costly.
Pilot cleaning
No two grey pipes should form a loop during cleaning; only a single grey pipe should be used for open circuit cleaning. The method involves connecting one end of the grey pipe to the cleaning unit, continuously preparing a certain concentration of cleaning solution in the mixture tank, and then continuously or intermittently injecting it into the grey pipe. This process requires adding cleaning equipment during shutdown, which increases costs.
Continuous cleaning without downtime
This process involves continuously injecting a certain amount of acidic solution while simultaneously introducing a specific quantity of ash-pipe running cleaning inhibitor and pipeline descaling agent. It is an open-loop cleaning process. The primary role of the cleaning additive is to promote the reaction between the acidic solution and ash deposits at a certain concentration and flow rate, while also increasing its solubility in water and reducing the occurrence of gas blockage, ensuring the quality of ash-pipe cleaning.
Operation procedure: 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 of the ash-removing corrosion inhibitor and pipeline cleaner stripper based on the flow rate of the gray water and the acidity. During the cleaning process, collect and test the acidity at the sampling point at the front of the ash pipe every 30 minutes, and strictly control the acidity by adjusting the acid flow rate. In the latter stage of the cleaning, test the pH value at the end of the ash pipe every 15 minutes. 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 friendliness, 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 all scale and blockages inside, revealing the metal substrate. With its immense energy and supersonic speed, the high-pressure water jet is fully capable of destroying hard scale and blockages, yet it has no destructive effect on metal.
Due to the pressure of high-pressure water being less than the compressive strength grade of metal, high-pressure cleaning will not damage the base material being cleaned.
(2) Fast Cleaning Speed: Due to the combined fracturing effects of water jet flushing, wedge splitting, shearing, and grinding, scaling can be quickly broken and removed, making the cleaning process several to ten times faster than traditional chemical methods, sandblasting and shot peening, simple mechanical, and manual methods.
Components cleaned with high-pressure water jetting do not require secondary cleaning; however, after chemical cleaning, the surface chemical 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 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, the spray can also reduce the dust concentration in the working 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. 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.
(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 easy to detach.
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 to 5 times that of ordinary steel. When lime scale accumulates on the boiler's heating surface, it severely deteriorates heat transfer efficiency and affects the boiler's performance; it can also 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 hastens the damage to the heating surface. Once lime scale forms, it should be promptly removed using mechanical or chemical methods.
