概述：
隨著社會(huì)經(jīng)濟(jì)和城市化的發(fā)展，城市及工業(yè)污水的產(chǎn)生及其數(shù)量在不斷增長(zhǎng)，固廢是污水處理后的副產(chǎn)品，是一種由有機(jī)殘片、細(xì)菌菌體、無機(jī)顆粒、膠體等組成的極其復(fù)雜的非均質(zhì)體，同時(shí)污泥中含有大量的有機(jī)物、腐殖質(zhì)等可利用資源，對(duì)固廢進(jìn)行前期處理后，可作為焚燒介質(zhì)、肥料、建筑材料、活性炭等。對(duì)于工業(yè)固廢、生活固廢過去一般采用填埋法進(jìn)行處理。隨著固廢的量越來越大，人們開始使用焚燒法，這種方法可以從固廢中有效地獲取熱能，減少環(huán)保成本并且不造成二次污染。另外，固廢也可作為有機(jī)肥料進(jìn)行深加工利用，但上述兩種處理方法仍需對(duì)固廢進(jìn)行干化或半干化處理。大量固廢產(chǎn)生，傳統(tǒng)的空心漿葉干燥機(jī)已無法滿足其烘干要求我們公司從國(guó)外引進(jìn)技術(shù)，采用圓盤式固廢干化機(jī)對(duì)多種物料進(jìn)行干化作業(yè)，采用不同形式的干化試驗(yàn)，進(jìn)行技術(shù)與能耗的經(jīng)濟(jì)分析，總結(jié)出圓盤式固廢烘干機(jī)是比較理想的節(jié)能干化設(shè)備。我公司對(duì)固廢干化進(jìn)行了多次升級(jí)換代和改型，形成我公司專有的技術(shù)及特點(diǎn)，以應(yīng)對(duì)大型固廢干化項(xiàng)目。
With the development of social economy and urbanization, the production and quantity of urban and industrial sewage are increasing. Solid waste is a by-product of sewage treatment. lt is an extremely complex heterogeneous body composed of organic debris, bacteria, inorganic particles, colloids and so on. At the same time, sludge contains a lot of organic matter and humus. lt can be used as incineration medium, fertilizer, building materials, activated carbon and so on. For industrial solid waste and life solid waste, landfil disposal was generally used in the past, With the increasing amount of solid waste. people bean to use incineration method, which can effectively obtain heat energy from solid waste, reduce environmentalcosts and do not cause secondary pollution,ln addition, solid waste can be further processed and utilized as oraanic fertilizer, but the above two methods still need to be dried or semi-dried, A large number of solid waste has been produced, and the traditional holow paddle dryer has been unable to meet its dryin requirements. Our company imports advanced technoloay from abroad, uses disc solid waste drver to drv various materials uses diferent forms of drying tests, carries out economic analysis of technology and energy consumption, and concludes that disc solid waste dryer is an ideal energy-saving drving equipment. Our company has uparaded and reformed the solid waste drying many times, forming our company's proprietary technology and characteristics, in order to cope with large-scale solid waste drying projects.
原理：
干化機(jī)主要由夾套，單軸轉(zhuǎn)子和傳動(dòng)裝置組成。固廢通過夾套，空心軸和軸上焊接的空心盤片的熱傳到被間接加熱干化。盤片對(duì)固廢沒有切割，而是通過盤片邊緣的推進(jìn)攪拌器的作用，對(duì)固廢進(jìn)行攪拌，不斷更新干化面，從而實(shí)現(xiàn)干化的目的。
The drying machine is mainly composed of jacket, single shaft rotor and transmission device. The solid waste passes throughthe iacket, hollow shaft and heat transfer from the hollow disc welded to the shat to be indirectly heated and dried. The disc does not cut solid waste, but mixes solid waste by pushing the agitator on the edge of the disc, and constantly updates the drying surface, so as to achieve the purpose of drying.
特點(diǎn)：
1.采用蒸汽傳熱介質(zhì)，既可用于半干化工藝也可用于全干化工藝，系統(tǒng)簡(jiǎn)單，輔助設(shè)備少。
2.設(shè)置空氣補(bǔ)給口，使尾氣排放更加順暢，尾氣處理系統(tǒng)負(fù)荷小。
3.可靠性高，持續(xù)運(yùn)行性好，可晝夜運(yùn)轉(zhuǎn)，適用于長(zhǎng)時(shí)間大處理量的固廢干化。
4.蒸汽與固廢不接觸，尾氣中不溶性氣體量少，可以入爐焚燒，二次污染少。
5.運(yùn)行時(shí)氧含量，溫度和粉塵濃度低，系統(tǒng)安全性好。
6.千化機(jī)通過外殼壁、中空軸及每個(gè)豎立圓盤的左右兩面進(jìn)行傳熱，傳熱面積大，結(jié)構(gòu)緊湊，外形尺寸小。
7.千化機(jī)內(nèi)部，固廢為濕固廢，為防止固廢粘結(jié)在轉(zhuǎn)盤上，在外殼內(nèi)警有固定的較長(zhǎng)刮刀，伸到圓盤之間的空隙
起到攪拌固廢，清潔盤面的作用。固廢經(jīng)破碎和攪動(dòng)后，呈均勻顆粒狀，有利于進(jìn)一步處置。
8.采用低溫?zé)嵩?s170C)加熱，圓盤上的固廢在停車時(shí)不會(huì)過熱，再次啟動(dòng)不受影響。
9.固廢處理負(fù)荷大，即使進(jìn)料不均勻也能保證平穩(wěn)運(yùn)行，內(nèi)部運(yùn)行阻力小，設(shè)備能耗低。
10.保養(yǎng)簡(jiǎn)單，持續(xù)運(yùn)行性好，可晝夜運(yùn)轉(zhuǎn)，保證每年8000小時(shí)運(yùn)行。
1. The steam heat transfer medium can be used in both semi-drying and full-drying processes. The system is simple and the auxiliary equipment is few.
2, the air supply port is set up to make the exhaust emission more smoother and the tal gas treatment system less load.
3. lt has high reliability, good sustainability and can operate day and night. lt is suitable for solid waste drying with long time andlarge capacity.
4. Steam is not in contact with solid waste, and the amount of insoluble gases in tail gas is less, so it can be incinerated in the furnace with less secondary pollution.
5. the oxygen content, temperature and dust concentration at runtime are low and the system is safe.
6, The drver conducis heat transfer throuah the shel wall. hollow shaft and the left and right sides of each vertical disc,The dryer has large heat transfer area, compact structure and small size.
7. In the dryer, solid waste is wet solid waste. In order o prevent solid waste from adhering to the turntable, there is a fixed ong scraper on the inner wall of the outer shell, which extends to the gap between the discs and plays the role of stiring solid waste and cleaning the disc surface. Ater solid crushing and agitation, the solid waste is uniform and granular, whicr is conducive to further disposal. , The solid waste on the disc will not overheat during parking and the restart will not be affected when heated by a lov temperature heat source (<170 C).
9. Solid waste treatment load is large, even if the feed is not uniform, it can ensure smooth operation, internal operation resistance is small, equipment energy consumption is low.
10. maintenance is simple, continuous operation is good, can run around the clock, ensure 8000 hours per year.
