中文拼音 [gāohánchénlǜ]
高含塵率
英文
heavy concentration of dust-
The main results are following : ( 1 ) the variation of clay / silt ratio can indicate the secondary clay action of dust depositions ; the variations of magnetic susceptibility and total fe content are inferred to be records of the changeable intensity of bio - pedogenesis ; the variations of sr content and rb / sr ratio can indicate bio - pedogenesis, dissolving and leaching action ; the content of total organic carbon ( toc ) can reflect variation of climate and vegetation during soil formation, it indicates the intensity of weathering and bio - pedogenesis ; the content variation of caco3 can show the intensity of dissolving - leaching action and secondary deposit, which was noted as pseudomycilia in pores and fissures in the sediment, so it can indicate the intensity bio - pedogenesis quite well. these proxy indexes also reflect obvious regional difference of pedogenic environment and the intensity bio - pedogenesis ; namely, secondary clay action, dissolving - leaching action and bio - pedogenesis are all much stronger in south than that in north
實驗結果表明：粘粒粉沙比值能很好地指示粉塵堆積物的次生粘化作用；磁化率和全鐵很好地指示生物風化成壤作用； sr和rb sr比值能很好的指示生物風化成壤作用和淋溶作用；總有機碳（ toc ）含量的高低，在一定程度上反應了土壤發育過程中氣候和植被狀況的變化，指示著成壤過程中腐殖質化的程度； caco3含量的變化，可以反映了黃土古土壤形成時的風化成壤作用的強弱程度，指示成壤過程中的淋溶作用和次生碳酸鹽化作用；並且各指標所指示的成壤環境和成壤強度存在明顯的區域差異，即渭河流域土壤的生物風化成壤作用、次生粘化作用和淋溶作用均表現出南部強于北部。Abstract : three - stage dust removal system of impinger, centrifugal dust collector, wet fibre - grid scrubber applying to dust collecting of driller in opencut mine is reported in this paper. the operational results show that this system has stable operation, higher dust removal efficiency, less drop pressure and dust concentration of outlet of the system meets emission standard
文摘:介紹了用慣性除塵器、旋風除塵器、濕式纖維柵除塵器組成的三級串聯除塵系統進行露天礦的鉆機收塵，運行結果表明該系統運行可靠，阻力小，除塵效率高，系統出口含塵濃度達到排放標準。Clk - proliferation cyclone applicable to the collection of non - fiber drying of granular dust is the main characteristics of a conical dongshen, thus reducing the dust since the dongshen gas exports to the centre to short - circuit the possibility and install a conical reflector screen to prevent the two air separation will have to roll up the dust down, brought out by the increased flow, thereby enhancing the efficiency of dust
Clk擴散式旋風除塵器，適用於捕集乾燥的非纖維性的顆粒狀粉塵，主要特點是筒身呈圓錐形，因而減少了含塵氣體自筒身中心短路到出口去的可能性，並裝有圓錐形的反射屏，防止兩次氣流將已經分離下來的粉塵重新捲起，被上升氣流帶出，因而提高了除塵效率。It has been shown that this updated sampling and measurement method, which can measure the content of tar and dust individually, appears much more precise and credible, particularly aiming at the characteristic of heavy tar and dust content in biomass gas. this clarification system that adopts two - level shell and tube condensers and one tar removal filter, has the advantages of high removal efficiency ( 97 % ~ 98 % ) and low operating cost. besides, it has been made more environmentally friendly considering that wastewater from condensers has measured up to related effluent state standards after being disposed in tar clarifier - tank
多次試驗表明：針對生物質氣浙江大學碩士學位論文含焦油灰塵量大的特點，改進的生物質焦油取樣測量法可實現焦油和灰塵的分離，有較高準確性和可靠性；採用二級管殼式冷凝器與一級乾式過濾器結合的燃氣冷凝凈化系統不但凈化效率高（ 97 98 ） 、運行費用低，而且含焦油廢水二經過澄清池澄清處理后可達到國家相關污水排放標準，避兔了濕式凈化系統的水污染；兼顧凈化效果、經濟性和減少污染考慮，採用以半焦為吸附材料的于式凈化系統可以達到炊用燃氣對焦油含量的要求。分享友人
