華星東方承建的愛拓環(huán)保1x2000t/d煙氣凈化工程開工建設(shè)
2020.01.09

  2019年12月4日,愛拓環(huán)保能源(浙江)有限公司造紙廢棄物資源綜合利用項目的煙氣凈化工程正式開工建設(shè),該工程項目為迄今為止全球單爐處理量最大的固廢處理項目,其在行業(yè)內(nèi)具有重要的劃時代意義,其比歐洲最大的瑞典Malar垃圾焚燒廠的單爐處理量還要大25%,其對中國乃至國際市場的行業(yè)經(jīng)驗(yàn)和工程數(shù)據(jù)積累具有重要意義。


  The flue gas cleaning system for the paper-making waste resource comprehensive utilization project of Aituo Environmental Protection Energy Co.,Ltd in Zhejiang Province was started its construction officially on December 4, 2019. Having become the world’s largest solid waste process project for single incinerator so far, this project has an epoch-making significance in the related industry. Its single-incinerator treatment capacity is at least 25 percent higher than that of the Malar Waste Incineration Plant in Sweden which is thought as the one having the highest single-incinerator treatment capcity in Europe.

Overall Effect Drawing of the Project


  該項目采用芬蘭Valmet的鍋爐,其煙氣工程由我司EPC總承包,并協(xié)調(diào)丹麥Niro共同參與該項目的設(shè)計。該項目不同于目前國內(nèi)千篇一律的套用設(shè)計工藝,針對項目的特定邊際條件,華星東方與Niro一同為該項目的煙氣工藝度身定做了較為適宜的煙氣凈化工藝。Niro公司由其總工Clause帶領(lǐng)團(tuán)隊與華星東方的工程師一起共同完成了項目的工藝設(shè)計和數(shù)據(jù)校核。


  This project uses the boilers of Valmet,Finland. Its flue gas cleaning project is contracted  by us in the form of EPC and Niro Company of Denmark was invited to jointly design with us for this project. Different from the current projects adopting the stereotyped designing process in China and based on the specific marginal conditions in this project, Huaxing East and Niro Company jointly designed the most suitable flue gas cleaning process for this project. Both the engineers from Niro headed by the Chief Engineer Clause and the engineers from HXET worked together to complete the process design and data verification for the project.  


  華星東方技術(shù)人員在多次出訪歐洲交流培訓(xùn),并通過實(shí)施和完成天津青光、張掖、山東高密等類似工藝的工程實(shí)踐后,與Niro共同合作實(shí)施了臨淄一期1x1000t/d、二期1x1000t/d之后,再次攜手合作實(shí)施愛拓環(huán)保能源項目。該項目的建成和投產(chǎn)將代表固廢行業(yè)領(lǐng)域的頂尖水平,為繼續(xù)推動固廢行業(yè)煙氣治理的工程實(shí)踐積累寶貴經(jīng)驗(yàn)。


  After they paid multiple visits to Europe where they had received the relevant professional trainings and finished their engineering practices of the similar process in the projects of Tianjing(Qingguang)Municipality City, Zhangye City as well as the projects of Gaomi City in Shangdong Province, the technical staff of HXET cooperated with Niro to complete the constructions of the first & second- stage projects of 1x1000TPD in Linzi City. After so many times projects cooperation, HXET and Niro cooperated again in the Aituo Environmental Protection Energy Project.  With the completion and commissioning of this project which represents the top level in the solid waste industry , this project really contributes to the valuable experience accumulation for engineering practice which can help further promote the flue gas treatment in solid waste industry.


丹麥Niro總工Clause先生與其團(tuán)隊與華星東方團(tuán)隊交流設(shè)計思路

Mr. Clause, Chief Engineer of Niro, Denmark, along with his team was exchanging design ideas with the HXET technical team.


  該項目新建1×2000t/d處理量垃圾焚燒鍋爐+1×N50MW汽輪發(fā)電機(jī)組。煙氣處理采用SNCR+爐內(nèi)噴鈣脫酸+靜電除塵器除塵+旋轉(zhuǎn)噴霧半干法+消石灰干法噴射+碳酸氫鈉噴射+活性炭噴射+袋式除塵+預(yù)留低溫SCR+飛灰輸送、儲存及穩(wěn)定化工藝,為我公司EPC工程。


  This project newly built a waste incinerator of 1×2000TPD and a steam turbine generator set of 1×N50MW. Its flue gas treatment adopts the combined processes of SNCR + Limestone Injection Deacidification Inside the Incinerator + ESP Dust Removal + SDA + Slaked Lime Dry Method Injection + Sodium Bicarbonate Injection + Activated Carbon Injection + BHF + Reserved Low Temperature SCR +  Fly Ash Transportation, Storage and Stabilization. It is our company’s EPC Project.


  該項目的一些新設(shè)計思路在于設(shè)計煙氣凈化工藝時,出于對控制飛灰處理成本的考慮,設(shè)計有靜電預(yù)除塵器,在投產(chǎn)后通過飛灰鑒別以期降低飛灰處理成本;在設(shè)置預(yù)除塵的脫除效率時,考慮了飛灰脫除效率對下游設(shè)備的煙氣操作露點(diǎn)的影響;在控制霧化器的選型時,考慮了半干法和不同工況的干法選擇的運(yùn)行配比,避免了霧化器選型過大,運(yùn)行人員難以操作的問題;在設(shè)計靜電除塵器時,通過張掖,高密等固廢領(lǐng)域的投產(chǎn)靜電除塵器的工程經(jīng)驗(yàn)反饋,針對含氯較高的煙氣和固廢行業(yè)普遍存在的飛灰特性惡劣的工況,同時也吸收了丹麥Amager Bakke焚燒廠靜電除塵器的一些優(yōu)化設(shè)計,對靜電除塵器做了大量的細(xì)節(jié)調(diào)整。


  Some new design ideas made in this project are listed as follows:When the FGC process was being designed, an ESP Pre-dedusting was added in order to control the flue gas treatment cost. After the production, the fly ash identification was introduced to reduce the fly ash treatment cost as well. When the removal efficiency of pre-dusting was set, the influence of fly ash removal efficiency on the flue gas operation dew point of the downstream equipment was fully considered.When the model of control atomizer was  selected, the operational ratios of Semi-dry Method and Dry Method under different operating conditions were also considered,which can effectively avoid the problems like: the size of atomizer chosen is too large or it is difficult for the staff to operate. When the ESP was designed, a substantial alterations were made based on the feedback from the engineering experiences of the operated ESP used in the solid waste field such as the projects of Zhangye City and Gaomi City. Its design fully considered the feature of flue gas which contains higher chlorine and the working conditions of poor fly ash characteristics prevailing in the solid waste industry. Its design also benefits from some of the optimized designs of ESP operated in Amager Bakke Incineration Plant, Denmark.





  目前,該項目正緊鑼密鼓地實(shí)施推進(jìn)中,該項目是華星東方2020年的重點(diǎn)工程項目之一,該項目投產(chǎn)后,將與華星東方執(zhí)行的上海松江二期2x850t/d、成都鄧雙2x880t/d、南昌3x880t/d、保定二期1x1000t/d、三河2x1000t/d等工程項目一樣,為行業(yè)積累寶貴的大型鍋爐煙氣凈化工程數(shù)據(jù),為中國固廢煙氣領(lǐng)域的企業(yè)走向世界前列積累更多的工程經(jīng)驗(yàn)。


  At present, Huaxing East is stepping up its effort to construct this project. As one of the key projects of HXET in 2020, this project can help accumulate the precious FGC engineering data of big-sized incinerators for the industry and more engineering experience for Chinese enterprises engaged in the flue gas cleaning industry of solid waste to compete internationally, just like what the projects in progress by HXET such as Songjiang Second-stage 2x850TPD, Shanghai Municipality and Dengshuang 2x880TPD,Chengdu Municipality,3x880TPD in Nanchang  Municipality, Second-state 1x1000TPD, Baoding City,2x1000TDP,Sanhe City did as before.
