天然气热风炉结垢了怎么办?厂家教你有效的解决办法

然气热风炉结垢的构成是因为水中的钙、镁离子受热后沉淀在热风炉内壁构成的,一旦热风炉有水垢呈现,要尽快铲除,否则会影响到热风炉的运用,也能够加阻垢剂避免水垢结在热风炉内壁。 燃气热风炉运用方法:依据热风炉每班补水总量,按每吨给水参加本品25-50克核算每班加药量,将阻垢剂参加给水箱,混合均匀后注入热风炉正常运转,按热风炉操作规则正常排污,排污量略大于正常排污量。补水硬度高时增加排污次数及排污量,排污时各排污点均应轮番排到,锅水碱度小于4mmol/L、PH低于10时,加碳酸钠调整到正常规范。 热水热风炉运用方法:依据热水体系总保有水量,按每吨参加本品25克核算体系总加药量,将总加药量通过补水箱一次性参加体系正常运转。
However, the composition of scaling in hot blast stove is due to the precipitation of calcium and magnesium ions in water on the inner wall of hot blast stove after heating. Once scaling appears in hot blast stove, it should be removed as soon as possible. Otherwise, it will affect the use of hot blast stove, and scale inhibitor can be added to avoid scaling on the inner wall of hot blast stove. Application method of gas hot blast stove: According to the total amount of hot blast stove water replenishment per shift, the dosage per shift is calculated according to 25-50 grams per ton of water to participate in the product. Scale inhibitor is added to the water tank, mixed evenly and injected into the normal operation of hot blast stove. According to the operation rules of hot blast stove, the normal discharge is normal, and the discharge is slightly larger than the normal discharge. When the hardness of replenishment water is high, the number of sewage discharge and the amount of sewage discharge should be increased. When the alkalinity of pot water is less than 4 mmol/L and PH is less than 10, the addition of sodium carbonate should be adjusted to the normal norm. Application method of hot water stove: According to the total amount of water retained in hot water system and the total dosage of 25 grams per ton of the product, the total dosage will be participated in the normal operation of the system through the water supply tank at one time. 热水热风炉在运用本品时应参加NaOH或Na2CO3将锅水PH值调整到10-20,碱度调整到4mmol/L以上。热水热风炉给水硬度小于2mmol/L时,本品用量可削减至每吨给水15克;热水热风炉给水硬度大于8mmol/L时用量应适当增加并加强排污,停炉时应将各排污阀全开,使污水排尽,并用清水冲清水渣以防阻塞。 能够上一套满足量大的全自动软化水设备处理结垢的现象,热水热风炉能够选用电子水处理仪,可是效果不大,也能够上一套比比赛小的全自动软化水设备。也能够在热风炉水中增加阻垢剂,可用于各种低压燃气热风炉、热水热风炉、蒸汽发生器、蒸馏水器、内燃机水冷却体系及其它热交换设备。能有用避免钙、镁离子堆积构成水垢,特别适用于给水中硫酸根离子和二氧化硅含量较高的区域,避免热风炉及热交换设备中结生难溶性水垢。在金属表面上构成保护膜,有用避免热风炉运转中的腐蚀损害。
Hot water stove should take part in NaOH or Na2CO3 to adjust the pot water PH value to 10-20 and alkalinity to 4 mmol/L or more when using this product. When the hardness of feed water is less than 2 mmol/L, the dosage of this product can be reduced to 15 grams per ton of feed water; when the hardness of feed water is greater than 8 mmol/L, the dosage should be increased appropriately and the sewage should be strengthened. When the furnace is shut down, all the sewage valves should be opened to drain out the sewage, and the slag should be flushed with clean water to prevent blockage. A set of fully automatic softening water equipment can be used to deal with scaling phenomenon, hot air stove can choose electronic water treatment instrument, but the effect is not very good, but also a set of fully automatic softening water equipment smaller than the competition. The scale inhibitor can also be added to the hot blast stove water. It can be used in various low pressure gas hot blast stoves, hot water hot blast stoves, steam generators, distillers, water cooling systems of internal combustion engines and other heat exchange equipment. It is useful to avoid the accumulation of calcium and magnesium ions to form scale, especially in areas with high sulfate ion and silicon dioxide content in feed water, and to avoid the formation of insoluble scale in hot blast stoves and heat exchange equipment. A protective film is formed on the metal surface to avoid corrosion damage during hot blast stove operation.
