在工业生产中,有许多工业拥有蒸气锅炉,由于工业用水处理不当,使蒸气锅炉内壁上挂上一层水垢。这样一来,导致锅炉热效率降低,浪费大量的燃料,使工业生产成本升高,而且到一定时期必须采用机械方式除垢,需停工停产,更换锅炉内套管,既费工又费时,同时给工业生产造成极大的损失。化学除垢法虽然简便,但是经化学除垢后的污水排放会造成地下水和江河的污染,长此以往,使自然环境污染,造成公害。另外,化学除垢会腐蚀锅炉内壁,严重影响蒸气
In industrial production, many industries have steam boilers. Due to the improper use of industrial water, a scale is stuck on the inner wall of the steam boiler. As a result, the thermal efficiency of the boiler is reduced, a large amount of fuel is wasted, the industrial production cost is increased, and mechanical descaling must be carried out for a certain period of time, shut down and production stoppage are required, and the casing in the boiler is replaced, which takes time and effort, Industrial production caused great losses. Although the chemical descaling method is simple, the sewage discharged after the chemical descaling will cause the pollution of groundwater and rivers. Over the long term, the natural environment will pollute and cause pollution. In addition, chemical descaling can corrode the inner wall of the boiler, seriously affecting the vapor
