四、結(jié)構(gòu)及工作原理 Structure and Working Principle
多筒式除塵機(jī)組是由一級(jí)圓盤(pán)預(yù)過(guò)濾器與二級(jí)多筒式濾塵器構(gòu)成的機(jī)電一體化除塵機(jī)組。第一級(jí)圓盤(pán)預(yù)過(guò)濾器主要過(guò)濾、分離、收集被處理空氣中的纖維和雜質(zhì);第二級(jí)多筒式過(guò)濾器主要過(guò)濾、分離、收集第一級(jí)過(guò)濾后空氣中剩余的微細(xì)纖塵和粉塵。
工作時(shí)，在主風(fēng)機(jī)的抽吸作用下，塵室內(nèi)呈負(fù)壓狀態(tài)，含塵氣流從入口處進(jìn)入本機(jī)，首先通過(guò)一級(jí)圓盤(pán)濾網(wǎng)，長(zhǎng)纖維和粗大雜質(zhì)被阻留在不銹鋼濾網(wǎng)上，旋轉(zhuǎn)吸嘴利用排塵風(fēng)機(jī)的風(fēng)力，將附著在濾網(wǎng)上的長(zhǎng)纖維和粗大雜質(zhì)吸除，通過(guò)纖維分離器分離，壓緊排出，分離后的含塵空氣返回一級(jí)箱體內(nèi)，細(xì)小粉塵隨氣流通過(guò)濾網(wǎng)進(jìn)入二級(jí)多筒式濾塵器，經(jīng)過(guò)長(zhǎng)毛絨濾筒過(guò)濾的潔凈空氣排到機(jī)外，被吸附到長(zhǎng)毛絨濾料表面的細(xì)微粉塵，由往復(fù)絲桿帶動(dòng)的旋轉(zhuǎn)吸嘴吸入布袋集塵器進(jìn)行塵氣分離，采用新型刷龍機(jī)構(gòu)落灰、粉塵通過(guò)粉塵壓實(shí)器壓緊排出，分離出的含塵空氣透過(guò)集塵布袋返回二級(jí)箱體，保證了長(zhǎng)毛絨纖維不堵塞，能連續(xù)有效工作，經(jīng)過(guò)過(guò)濾的潔凈空氣透過(guò)濾筒排到機(jī)外。
This system is combined of two units of filters. The 1st one is a disc for pre-filtering, and 2nd one is a multi-drum filter. The first one is to pre-filter, separate, collect the fibers and impurities in the air flow. The second one is to filter, separate and collect the rest tiny dusts and fibers rest in the air flows out of the 1st one.
When being sucked by the main motor, the dust room is under negative air pressure, air flow with dusts enters this system by inlet, through the 1st disc filtering screen, long fibers and thick impurities is left on the stainless filtering screen, which will be sucked off by rotating suctions with the negative air pressure generated by dust-exhaust motor, and then separated and compressed by Fiber Separator before extracted. The air will go back to the first grade box, while the air flow with tiny dusts enters the 2nd grade multi-drum filter, clean air will then be exhausted to outer side through plush filter. Those tiny dusts left on the flush surface will be sucked into the cloth-bag dust collector by the suction (driven by traverse guide screw), and thus the air is filtered out, while dusts left inside the cloth-bag, and then compressed before being extracted.
五、工藝計(jì)算與選型 Process calculation and model selection
Q=KQom3/h
Q——處理風(fēng)量 Air volume being handled
K——選用系數(shù)，根據(jù)處理空氣的含塵濃度和系統(tǒng)漏風(fēng)率等因素確定。一般為1.1—1.3含塵濃度高或漏風(fēng)率大時(shí)應(yīng)按上限選擇，反之按下限選擇。Selection index, decided by the dust density of the air to be handled and air leakage rate of system. Normally 1.1~1.3, but it should be at the upper limit if high dust density or high air leakage, lower limit on the contrary.
Qo——理論計(jì)算處理風(fēng)量 Theoretical calculation of the air volume to be handled
根據(jù)Q值按本機(jī)組推薦風(fēng)量選擇合適的機(jī)型。
當(dāng)進(jìn)入本機(jī)組氣流中含塵雜質(zhì)量較大或場(chǎng)地條件許可的情況下，盡可能選取較大規(guī)格的機(jī)型，盡可能不按本機(jī)組最大風(fēng)量選擇機(jī)型規(guī)格，以降低濾塵設(shè)備的阻力，降低能耗，節(jié)約運(yùn)行成本。
By data Q, select the appropriate type of system according to air volume recommended below.
When the air flow enters this system with bigger mass impurities, or, when the space area permits, please select as larger specification system as possible, try best to not select based on max. handling air volume, in order to reduce the resistance of filter equipment, reduce the energy cost, save operation cost.
