熱風爐在工業方面的耗能和排放問題

熱風爐廠傢在工業方面成都收賬耗能和排放問題,环保類成都找人公司熱風爐現如今幾乎成為每傢每戶工業生產類成都收賬廠傢都會選擇使用收賬一款設備.但也有很多人關心這款熱能設備成都找人公司性能問題.下面熱風爐廠傢主要針對此類問題進行以下分析。
Hot-blast stove manufacturers in industrial energy consumption and emission problems, environmental protection type of hot-blast stove is now almost every industrial manufacturer will choose to use a device. But there are many people concerned about the performance of this thermal equipment. Hot-blast stove manufacturers mainly focus on the following analysis of such problems.熱風爐廠傢熱風爐廠傢發現，目前使用熱風爐設備的工業廠傢為鋼鐵類的居多，工業廠傢為降低高爐煉鐵工序的能耗,建立瞭包含高爐、爐頂煤氣餘壓回收透平發電裝置(TRT)、鼓風機和熱風爐在內的高爐煉鐵工序優化模型,該優化模型包含瞭原燃料參數和工藝參數在內的9個優化變量,設定瞭變量上下限約束、工藝約束、物質和能量平衡約束等31個線性和非線性的約印花地坪束條件,並利用序列二次規劃法(SQP)求解該優化問題。優化結果表明:要使高爐煉鐵工序能耗最小,應增大煤比、降低焦比、提高鼓風溫度和采用高壓爐頂操作。同時利用該優化模型和算法,分析瞭煤比、鼓風濕度、鼓風溫度和鼓風富氧率對工序能耗及相應的TRT發電量的影響規律。
Hot blast furnace manufacturers found that most of the industrial plants using hot blast furnace equipment are iron and steel. To reduce the energy consumption of blast furnace ironmaking process, industrial manufacturers established an optimization model of blast furnace ironmaking process including blast furnace, top gas residual pressure recovery turbine power generation device (TRT), blower and hot blast stove. The model includes 9 optimization variables including raw fuel parameters and process parameters. 31 linear and non-linear constraints such as upper and lower limit constraints, process constraints, material and energy balance constraints are set. The optimization problem is solved by sequential quadratic programming (SQP). The optimization results show that in order to minimize the energy consumption of blast furnace ironmaking process, the coal ratio should be increased, the coke ratio should be reduced, the blast temperature should be increased and the operation of high pressure furnace top should be adopted. At the same time, using the optimization model and algorithm, the 环氧地坪effects of coal ratio, blast temperature, blast oxygen enrichment rate on process energy consumption and corresponding TRT power generation were analyzed.
針對熱風爐助燃風機系統普遍存在的高能耗問題,以某鋼鐵企業煉鐵廠2#高爐熱風爐助燃風機為例,介紹瞭變頻改造技術和更換高效節能風機技術在該助燃風機中的應用,並對這兩種改造技術從運行安全性、節能量、施工便捷性、一次性投入和後期維護角度進行對比分析,結果表明更換高效節能風機技術相對變頻改造技術而言更具有優越性,值得推廣。
Aiming at the problem of high energy consumption commonly existing in the fan system of hot blast stove combustion-supporting, taking the fan system of 2# blast furnace in an iron and steel enterprise as an example, this paper introduces the application of frequency conversion transformation technology and replacing high-efficiency energy-saving fan technology in the fan system, and discusses the two transformation technologies from operation safety, energy-saving quantity, construction convenience, and one is the application of frequency conversion transformation technology and replacing high-efficiency energy-saving fan technology in the fan system. The results show that the technology of replacing high-efficiency and energy-saving fan has more advantages than the technology of frequency conversion transformation, and it is worth popularizing.
因為熱風爐廠傢提出瞭一種基於送風溫度預測實現的成都找人公司系統,該系統為可變周期運行和控制。它以整個成都***系統的最低送風溫度作為總的控制指標,采用基於實例的方法推理預測送風結束時間,並根據預測結果動態地調節後續送風成都***的燃燒終點,從而使各個熱風爐在燃燒階段所積蓄的熱量得到充分的釋放,以達到降低煤氣消耗和減少熱風溫度波動的雙重目的。
Because the hot blast stove manufacturer puts forward a hot blast stove system based on the prediction of supply air temperature, which can operate and control in variable period. It takes the lowest air supply temperature of the whole hot-blast stove system as the total control index, uses case-based reasoning to predict the end time of air supply, and dynamically adjusts the end point of combustion of the follow-up hot-blast stove according to the predicted results, so that the heat accumulated by each hot-blast stove in the combustion stage can be fully released, so as to achieve a reduction. The dual purposes of gas consumption and reduction of temperature fluctuation of hot air are discussed.
