以提高褐煤機和熱源選擇的效率的方式
影響原料水分含量褐煤烘干機烘干設備的結果是什么呢?為原料的特別高的水分含量,干燥也難以充分,因此干燥該原料后會濕潤。不能滿足生產要求。如水蒸氣,水蒸氣通過散熱器加熱干燥介質鍋爐加熱,這是間接加熱的兩倍,這樣,總的熱效率非常低,只有40%左右。間接加熱的熱空氣潔凈無塵,熱效率60?70%。其次,烘干機熱源的選擇。熱源選擇對于褐煤烘干機,根據(jù)燃料分為煤,石油,天然氣,電力等根據(jù)傳熱條件點干燥器熱源照常密鑰可分為直接加熱介質和間接加熱干燥。和由油煙污染直接加熱,影響了產品的質量,但使用良好的熱,熱效率是非常高的,褐煤干燥器來干燥的材料與少量的煙霧和沒有影響的,可以是優(yōu)選的。褐煤干燥過程中存在的問題,易產生異味,需要除塵脫臭處理,能耗大或加工費,干污泥波動的市場需求,市場缺乏的,也有可燃性粉塵防爆安全隱患和設備技術問題如的污泥干燥處理成本嚴重磨損高 設備材料:鑒于污泥和不可預知的變化的特點,沒有人知道不銹鋼可以解決一切問題。因為褐煤具有耐酸堿,耐腐蝕性,所以干燥器廠家優(yōu)先設備經受的變化?機械設備工傷事故不在于是否能保證?以確保該設備本身能滿足要求,并要求操作人員掌握的基本操作方法。然而,在干燥設備領域,鐵的主要材料仍是有一定的技術,使理性的選擇主要是成本,一些大型技術設備不能使用高金屬材質,但這樣會降低使用壽命,提高了投資成本。
The way to enhance the efficiency of the lignite dryer and heat source selection
Affect the outcome of lignite dryer drying equipment of raw material moisture content is what? For particularly high moisture content of raw material, a drying it is difficult to fully, therefore after drying the raw material will be moist. Can not meet the production requirements. Such as boiler heating of water vapor, vapor through the radiator heating drying medium, this is the indirect heating twice, this way, the total thermal efficiency is very low, only about 40%. Indirect heating hot air clean clean, thermal efficiency is 60 ~ 70%. Secondly, the dryer heat source selection. Heat source selection is the key for lignite dryer, dryer heat source as usual according to the fuel divided into coal, oil, gas, electricity, etc. According to heat transfer condition points can be divided into the medium directly heating and indirectly heating drying. And directly heated by soot pollution and affect the quality of the product, but use good heat, thermal efficiency is very high, lignite dryer to dry the material with a small amount of smoke and no effect, can be preferred. Lignite drying process there is a problem, easy to produce odor, need to dedust deodorization treatment, large energy consumption or processing fees, the market demand of dry sludge volatility, lack of market, there are combustible dust explosion safety hidden trouble and device technical problems, such as severe abrasion of sludge drying processing cost is high Equipment material: in view of the characteristics of the sludge and unpredictable change, no one was sure stainless steel can solve all problems. Because the lignite has acid and alkali, corrosion resistance, so the dryer manufacturers priority equipment withstand the changes? Mechanical equipment inductrial injury accident is not whether can guarantee? To ensure that the equipment itself to meet the requirements, and require operators to master the basic operation method. However, in the field of drying equipment, the main materials of iron is still a certain technology, make the choice of reason mainly is the cost, some large technical equipment can‘t afford to use the high metal material, but this will reduce the service life, improve the investment cost.
