談談熱風爐的節能減排趨勢

 

我國工業和生活用低壓工業,每年消耗標煤近6億噸。如果50%用戶能夠將高熱量冷凝水直接回用做補水,將是節能減排重要舉措。它會明顯減少燃料消耗量和軟化水量產量,降低蒸汽生產成本,並且由于冷凝水回用後,內的水質改善,還會減少的排污熱損失,提高熱效率。從某種意義上來說,其節約用水、節約能源和保護環境的社會效益甚至可能要超過直接得到的經濟效益。

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.

現階段,國家在不斷提高節能減排國策的執行力度,提出在社會發展進程中,節約能源不是簡單的減少能源的使用量,而是要通過采用新的節能技術、新工藝和新設備來提高能源的利用率。作為一種常用的設備,其節能減排刻不容緩。今天,环亚ag旗舰厅就來詳細說一說。

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.

使用範圍廣,普遍存在一些中國獨特的問題。盡管有些廠采用了進口的,但管線還是碳鋼的,氧腐蝕和CO2腐蝕嚴重,導致冷凝水鐵離子超標問題很普遍。高含量的鐵離子水在中會是一個不安全的因素,引起熱風爐壁的坑蝕和點蝕,造成熱風爐穿孔報廢。

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. 在中高壓工業熱風爐中,鐵離子含量相對比較低,常采用犧牲樹脂和活性炭復合雙層膜,以及保安過濾方式去除冷凝水中的鐵離子。冷凝水含鐵超過國家熱風爐水質標準,不能直接回用的另一個︰κ︰60%-70%以上的低壓熱風爐排污率高于15%-25%,而國家標準是5-10%,大的高溫水排污是我國熱風爐能耗高的主要原因。已經引起相關部門的重視,是亟待解決的難題。

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.

隨著科技的發展,熱風爐的過濾方式、濾料的選擇和反洗方式的創新上做出了改革,研發出適用于中國國情的冷凝水除鐵技術。采用這個技術,可以將高溫冷凝水直接回用,會使過去的排污率下降7%-15%。設備使用後3-6個月就可以通過冷凝水的回用收回投資成本,對工業熱風爐的運行節能節水意義重大。

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.
