我国工业和生活用成都收账低压工业热风炉,每年消耗成都找人公司标煤近6亿吨。如果50%成都收账用户能够将高热量收账冷凝水直接回用做热风炉补水,将是节能减排成都找人公司重要举措。它会明显减少热风炉燃料消耗量和软化水量产量,降低蒸汽生产成本,并且由于冷凝水回用后,热风炉内的水质改善,还会减少热风炉的排污热损失,提高热风炉热效率。从某种意义上来说,其节约用水、节约能源和保护环境的社会效益甚至可能要超过直接得到的经济效益。
China's industrial and domestic low pressure industrial hot stove consumes nearly 6 billion tons of standard coal per year. If 50% of users can directly reuse the condensate water with high calorific value as hot stove water supply, it will be an important measure of energy saving and emission reduction. It can obviously reduce fuel consumption and soften water output of hot blast stove, reduce steam production cost, and improve the water quality of hot blast stove after reuse of condensate water. It can also reduce the heat loss of hot blast stove and improve the thermal efficiency of hot blast stove. In a sense, the social benefits of water saving, energy saving and environmental protection may even exceed the direct economic benefits.
现阶段,国家在不断提高节能减排国策的执行力度,提出在社会发展进程中,节约能源不是简单的减少能源的使用量,而是要通过采用新的节能技术、新工艺和新设备来提高能源的利用率。热风炉作为一种常用的设备,其节能减排刻不容缓。今天,我们就来详细说一说。
At the present stage, the state is constantly improving the implementation of the national policy of energy conservation and emission reduction. It is proposed that in the process of social development, energy conservation is not simply to reduce the use of energy, but to improve the utilization of energy through the adoption of new energy-saving technologies, new processes and new equipment. As a common equipment, hot stove is imperative for energy saving and emission reduction. Today, let's talk about it in detail.
成都找人公司使用范围广,普遍存在一些中国独特的问题。尽管有些厂采用了进口的成都收账公司,但管线还是碳钢的,氧腐蚀和CO2腐蚀严重,导致冷凝水铁离子超标问题很普遍。高含量的铁离子水在成都收账公司中会是一个不安全的因素,引起热风炉壁的坑蚀和点蚀,造成热风炉穿孔报废。
There are many unique problems in China. Although some factories adopt imported hot blast stoves, the pipelines are carbon steel. Oxygen corrosion and carbon dioxide corrosion are serious, which leads to the problem of excessive iron ions in condensate water. High content of iron ion water is an unsafe factor in hot blast stove, which causes pitting and pitting corrosion of hot blast stove wall and causes perforation and scrap of hot blast stove. 在中高压工业热风炉中,铁离子含量相对比较低,常采用牺牲树脂和活性炭复合双层膜,以及保安过滤方式去除冷凝水中的铁离子。冷凝水含铁超过国家热风炉水质标准,不能直接回用的另一个危害是:60%-70%以上的低压热风炉排污率高于15%-25%,而国家标准是5-10%,大的高温水排污是我国热风炉能耗高的主要原因。已经引起相关部门的重视,是亟待解决的难题。
In medium and high pressure industrial hot blast stoves, the iron ion content is relatively low. Sacrifice resin and activated carbon composite double-layer membranes are often used to remove iron ions from condensate water by security filtering. The condensate water contains more iron than the National hot blast stove water quality standard. Another hazard that can not be directly reused is that the discharge rate of low pressure hot blast stoves with 60% - 70% or more is higher than 15% - 25%, while the national standard is 5 - 10%. Large high temperature water discharge is the main reason for high energy consumption of hot blast stoves in China. It has caused the attention of relevant departments and is a difficult problem to be solved.
随着科技的发展,热风炉的过滤方式、滤料的选择和反洗方式的创新上做出了改革,研发出适用于中国国情的冷凝水除铁技术。采用这个技术,可以将高温冷凝水直接回用,会使过去的排污率下降7%-15%。设备使用后3-6个月就可以通过冷凝水的回用收回投资成本,对工业热风炉的运行节能节水意义重大。
With the development of science and technology, the innovation of hot blast stove's filtration mode, filter material selection and backwashing mode has been reformed, and the condensate iron removal technology suitable for China's national conditions has been developed. With this technology, the high temperature condensate can be directly recycled, and the sewage rate will be reduced by 7%-15% in the past. The investment cost can be recovered through the reuse of condensate water 3-6 months after the use of the equipment, which is of great significance for energy saving and water saving in the operation of industrial hot blast stoves.
