Chemical cleaning descaling process:
Recirculating Closed Loop Cleaning
Recirculating cleaning utilizes two existing parallel ash removal pipelines to form a loop, creating a circulating system with the cleaning pump station. It introduces a solution of a certain acidity concentration, which circulates through the ash water pipes for cleaning. As the acid cleaning 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 recirculating loop for cleaning. This process must be carried out during shutdown and is complex and costly.
Open road 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 unit, continuously preparing a certain concentration of cleaning solution in the liquid mixing tank, and then injecting it into the grey 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 the ash pipe is operating normally without interruption, simultaneously adding a certain quantity of ash-pipe running cleaning inhibitor and pipeline descaling agent for open-circuit cleaning. The primary function of the cleaning aid is to promote the reaction between the acidic solution and the ash scale at a specific concentration and flow rate, while also enhancing its solubility in water, reducing the formation of air blockages, and 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 for the washing inhibitor and pipeline cleaner剥离剂 according to the sludge water flow and acidity. During cleaning, take a sample at the front sampling point 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 every 15 minutes at the end of the sludge pipe 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 cleaning equipment:
High-pressure water jetting for 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 - High-pressure water jet cleaning of pipe and heat exchanger bores can completely remove scale and blockages inside, revealing the metal surface. The high-pressure water jet, with its immense energy and supersonic speed, can fully destroy tough scale and blockages without causing any damage to the metal.
High-pressure water cleaning will not damage the base material being cleaned, as the pressure is less than the compressive strength grade of the metal.
(2) Fast Cleaning Speed: Due to the combined action of jet washing, wedge splitting, shearing, and grinding, scaling can be quickly broken and removed, making the cleaning speed several to tens of times faster than traditional chemical methods, sandblasting, simple mechanical, and manual methods.
Additionally, parts 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, 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 include carbonate scale, sulfate scale, silicate scale, and mixed scale, among others. 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: a solid scale that firmly adheres to the pot shell and pipe walls, and a loose sediment that is easily detached.
Lime scale primarily forms due to the salts of calcium, magnesium, and other elements in the boiler feed water precipitating and adhering 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 impairs heat transfer efficiency and affects the boiler's performance; it can also easily damage metal materials due to localized overheating, potentially leading to tube explosion accidents; it 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.
