【摘要】：紡織印染業(yè)是浙江傳統(tǒng)優(yōu)勢產(chǎn)業(yè),但污染排放較大。對于印染污泥的處理處置問題,還沒有針對性解決方法,主要是借鑒城市污泥的處理方法,無法實現(xiàn)資源化。在能源日益短缺、環(huán)境污染越來越嚴重的今天,清潔、環(huán)保、經(jīng)濟地干化印染污泥是發(fā)展趨勢。本文就浙北地區(qū)印染企業(yè)的發(fā)展形勢,提出以印染污泥“就地混燒”的資源化利用為目的處理路線,通過對太陽能干燥技術(shù)和污泥低溫干燥技術(shù)、熱泵干燥技術(shù)的研究,首次提出了熱泵輔助式太陽能聚光干燥的設計思路；結(jié)合CPC聚光集熱技術(shù)、真空集熱管結(jié)構(gòu)以及轉(zhuǎn)筒干燥的優(yōu)勢,設計并制作了轉(zhuǎn)筒式CPC聚光干燥器樣機,進行了實驗研究和生產(chǎn)模擬測試。主要的成果如下：(1)設計并搭建了熱泵輔助式太陽能污泥干燥實驗臺。實驗測試分析了干燥管內(nèi)空氣和內(nèi)壁在一天內(nèi)的溫度變化趨勢,驗證了干燥管的溫度已達到實際干燥需要,可實現(xiàn)的溫度范圍在60℃-110℃。在無熱風情況下,一天內(nèi)維持在60℃以上的干燥時間在6個小時。在熱風介入下,可保證在光照不足時的干燥溫度,實現(xiàn)全天候正常工作。(2)進行了印染污泥干燥實驗,記入在不同的溫度(60℃、80℃、90℃)、不同的顆粒大小(6mm、8mm、10mm)的三種干燥模式下所需要的干燥時間。分析了干燥管內(nèi)橫向溫差對于物料干燥的影響。同時與傳統(tǒng)熱風干燥器相比,干燥轉(zhuǎn)筒的設計有利于保持物料的原始形狀,太陽能聚光集熱管的設計可降低了干燥筒沿物料前進方向上的溫差。(3)本文制作的轉(zhuǎn)筒式CPC聚光集熱干燥管的集熱效率可在40%左右。通過實驗和計算得出試驗樣機可實現(xiàn)的印染污泥日處理量在10.678kg/(d·m2)左右。理論上推算,300m2的接受面積可實現(xiàn)每天3.2噸的處理量,基本達到了浙北地區(qū)中小型印染企業(yè)的處理需要。同時相比于單獨用電加熱送風干燥,太陽能熱風聯(lián)合加熱干燥的耗電量降低了40.63%,單獨太陽能加熱干燥耗電量降低了73.3%。(4)從實驗數(shù)據(jù)中分析計算,得出在提供熱風80℃時三種干燥模式下印染污泥的能耗分別為0.551KW·h/kg,0.181KW·h/kg,0.928KW·h/kg。參考目前浙江工業(yè)用電平均成本1元／度,得出三種模式下的污泥的處理成本551元／噸、181元／噸、928元／噸。
[Abstract]:Textile printing and dyeing industry is Zhejiang traditional advantage industry, but the pollution emission is bigger.As for the treatment and disposal of printing and dyeing sludge, there is no specific solution, which mainly refers to the treatment method of urban sludge and can not be used as a resource.Nowadays, with the shortage of energy and environmental pollution, clean, environmental protection and economical drying of printing and dyeing sludge are the development trend.According to the development situation of printing and dyeing enterprises in the north of Zhejiang province, this paper puts forward a new way to deal with the resource utilization of printing and dyeing sludge "in situ", through the research of solar energy drying technology, sludge low temperature drying technology and heat pump drying technology.The design idea of heat pump assisted solar condensing drying is put forward for the first time, and the prototype of rotary cylinder CPC condenser is designed and manufactured by combining the CPC collector technology, the structure of vacuum collector and the advantages of rotary cylinder drying.Experimental research and production simulation test were carried out.The main results are as follows: (1) the heat pump assisted solar sludge drying experiment bench is designed and built.The temperature variation trend of air and inner wall in a single day has been tested and analyzed. It is verified that the temperature of drying pipe has reached the actual drying requirement, and the achievable temperature range is from 60 鈩，
