Case introduction

水垢 的一种化学药剂,广泛适用于电锅炉除垢、 燃油锅炉 除垢、 燃气锅炉 除垢、燃煤锅炉除垢、 开水炉 除垢、 热水锅炉 除垢, 采暖锅炉 除垢、浴池锅炉除垢、 蒸汽锅炉 除垢及板式换热器除垢等。 Boiler cleaning is commonly known as boiler descaling. As the name implies, it refers to a chemical agent that can remove scale inside the boiler . It is widely used in electric boiler descaling, oil boiler descaling, gas boiler descaling, coal-fired boiler descaling, and boiling water. Furnace descaling, hot water boiler descaling, heating boiler descaling, bath boiler descaling, steam boiler descaling, and plate heat exchanger descaling.

 

把水加热后一部分水蒸发了,本来不好溶解的 硫酸钙 ( CaSO4 ,石膏就是含 结晶水 的硫酸钙)沉淀下来。 After the boiler heats the water, a part of the water evaporates, and calcium sulfate ( CaSO4 , gypsum, which is crystal sulfate containing crystal water ) , which was originally insoluble, precipitates. 碳酸氢钙 ( Ca(HCO3)2 )和 碳酸氢镁 (Mg(HCO3)2),在加热的水里分解,放出二氧化碳(CO2),变成难溶解的 碳酸钙 ( CaCO3 )和 氢氧化镁 Mg(OH)2 )也沉淀下来,有时也会生成MgCO3,这样就形成了 水垢 The original dissolved calcium bicarbonate ( Ca (HCO3) 2 ) and magnesium bicarbonate (Mg (HCO3) 2) are decomposed in heated water, releasing carbon dioxide (CO2), and become calcium carbonate ( CaCO3 ) and hydrogen which are difficult to dissolve. Magnesium oxide ( Mg (OH) 2 ) also precipitates, and sometimes MgCO3 is also formed, thus forming scale . It can be roughly divided into two types, hard scale and soft scale, according to the cause of formation and the difference in the forming state. 锅炉除垢剂 . The main components of scale are calcium carbonate and magnesium hydroxide, which can be chemically changed with acid, so in other words, you can use acid-containing chemicals to remove boiler scale. This composite agent is boiler scale remover .

 

冷却水系统 汽车水箱 以及民用水壶、热水器中水垢的专用化学品,除垢速度快,对金属无任何腐蚀。 D-9100 is a special chemical for removing scale in boilers, evaporators, heat exchangers, cooling water systems , automobile water tanks, and civilian kettles and water heaters. It has a fast descaling speed and does not corrode metals. And non-toxic, tasteless, short-term contact does not burn the skin, efficient and safe, easy to use. After descaling, a gray protective film is formed on the metal surface. Mix this product into an 8-10% aqueous solution, pump it into the cleaning object, or directly add it to the water tank and kettle, the temperature is 30-65 ° C (not more than 80 ° C), the time is 3-8 hours, and the sewage can be drained. . If you use the immersion method, it will take about 24 hours to completely remove the limescale.

 

The first step of boiler cleaning: First, understand the structure, material and heat exchange method of boiler cleaning boiler. There are dozens of boilers used on the market. Each type of heat exchange method, structure and material is different, and different cleaning methods are adopted for different structures and different materials. It is necessary to analyze and test different regions, different water quality and different scales, configure different chemical cleaning agents for different materials and different scales, and formulate scientific and reasonable cleaning schemes.

Boiler cleaning The internal components of the boiler can be operated efficiently and benignly, effectively eliminating accidental hidden dangers. After cleaning, it can effectively reduce the load of main components such as water pumps, heat exchangers, reduce the wear of operating components, and reduce the failure rate. If the boiler is cleaned and maintained every two years, the service life of the equipment can be extended by 3-5 years. It can improve the heating efficiency of the boiler and reduce the gas consumption. Experiments show that after cleaning the boiler, 25% -30% of energy can be saved on the original basis.

Boiler is a kind of heat exchange equipment. In this way, scale will be formed during the heating and continuous injection of cold water, and the scale will accumulate more and more, so the heat exchange efficiency of the boiler will be greatly reduced, which is mainly reflected by the increase of boiler gas consumption. Symptoms such as insufficient heating, cold and hot sanitary hot water, and a decrease in the amount of hot water can severely damage the boiler liner. 燃气锅炉 在使用二至三年后就必须要对其进行清洗保养。 Therefore, any gas boiler must be cleaned and maintained after two to three years of use.

除垢清洗 The most important working procedure of boiler cleaning is the first step: descaling and cleaning . 循环水 内按比例加入配置好的除垢清洗剂,进行锅炉清洗除垢,根据垢量多少确定清洗循环的时间和加入药剂多少,确认全部垢质清洗下来之后转入下一步清洗程序。 In the circulating water of the cleaning tank, add the configured descaling cleaning agent in proportion to perform boiler cleaning and descaling. Determine the cleaning cycle time and the amount of reagents according to the amount of scale. After confirming that all the scale has been cleaned, move to the next cleaning program. .

Step 2: Wash with water. 清洗设备 和锅炉连接好后,要用清水循环清洗10分钟,检查系统状态,是 否有泄漏,同时将浮锈清洗掉。 After connecting the cleaning equipment to the boiler, use clean water to cycle for 10 minutes, check the system status, and check for leaks, and clean the floating rust at the same time.

The third step: peel anti-corrosion cleaning. 除垢清洗 时清洗剂对清洗 部件产生腐蚀。 Add the surface stripper and slow release agent to the circulating water of the cleaning tank in proportion, and cycle cleaning for 20 minutes to separate the scale and the parts cleaned. At the same time, anti-corrosion treatment is performed on the surface of the object without scaling to prevent descaling and cleaning . The cleaning agent corrodes the cleaning parts.

钝化 镀膜处理 The fourth step: passivation coating treatment . Add passivation coating agent to passivation coating treatment for boiler cleaning system to prevent corrosion of pipelines and components and new rust and scale.
