KN-LT Model Down Flow Type Cartridge Filter

概述 Overview

KN-LT型沉流式濾筒除塵器是本公司在引進消化吸收國外DFT型濾筒式除塵器先進技術的基礎上，結合國內實際情況研制開發的高效除塵器。因其具有結構合理、除塵效率高、實用性強、占地面積小、節能效果顯著、節約基建投資和維修方便等眾多優點而被廣泛應用于建材、輕工、冶金、化工等行業中。在過濾除塵系列中與常用的袋式除塵器相比屬于新一代的產品。

On the basis of introducing，absorbing and assimilating the advanced technology of foreign DFT model cartridge filter, the KN-LT model down flow type cartridge filter is a kind of efficient dust remover developed by the company combining with the domestic actual situation. Because of its reasonable structure, high dust removal efficiency, strong practicability, small floor area, remarkable energy-saving effect, capital outlay saving and convenient maintenance it’s widely used in building materials, light industry, metallurgy, chemical industry and other industries. Compared with the conventional bag filter, the filter belongs to a new generation of products.

濾筒結構及其特性

? 剛性濾料成折疊式均勻分布組成濾筒，使其具有較小的體積，發揮較大的過濾面積效應。

? 在普通濾料的外層，再覆蓋一層超細纖維層，從而使過濾效果有了本質的提高。被過濾粉塵僅停留在濾料超細纖維層的外表，所以大大減少了過濾阻力，節省耗電 30%以上，節能效果顯著，并且清灰十分徹底。同時也解決了超細粉塵、纖維性粉塵難以處理等各類難題。

? 選用 PTFE覆膜濾料適用于潮濕的含塵氣體，由于濾料與水的接觸角大于108度，使得附著于濾料表面的潮濕粉塵不粘濾料，極易吹落，因而，徹底解決了潮濕粉塵結露粘料的問題。

? 過濾效率：普通濾料為 5μm以上粒徑粉塵收集能力為99.9%，覆膜濾料為0.5μm以上粒徑粉塵收集能力為99.9%。

? 普通濾筒的正常使用溫度為 80℃（如訂貨時加以說明，使用溫度可達130℃）。

Filter cartridge structure and characteristics

? The rigid filter materials are uniformly distributed in folding mode and compose the filter cartridge, thus the cartridge can have the smallest volume, and play a maximum filtering area effect.

? The outer layer of ordinary filter materials is covered with a layer of superfine fiber, so that the filtering effect has substantial improvement. The filtered dust only stays on the surface of superfine fiber layer of the filter materials, so the filter resistance is greatly reduced, the power consumption is saved to over 30% , the energy saving effect is remarkable, and the ash removal is thorough. At the same time, a variety of problems are solved such as the ultrafine dusts and fibrous dusts.

?The PTFE membrane filter material is suitable for moist dust contained gas. Since the contact angle between the filter material and the water is greater than 108 degrees, the wet dust sticking to the filter material surface doesn’t adhere to the filter material and is easily blown away. Therefore, the problem of moisture condensation and material sticking of wet dust is completely solved.

?Filtration efficiency: the ordinary filter material has grain size of above 5 μm, and the dust collection capacity is 99.9%. The membrane filter material has grain size of above 0.5 μm, and the dust collection capability is 99.9%.

?The normal usage temperature of ordinary filter cartridge is 80 ℃(if stated in order, the usage temperature can reach 130 ℃).

機組結構

? 采用了先進的沉流式布局及濾筒斜裝結構，因而除塵器在工作過程中同步清灰效果好。

? 塵氣入口設置擋塵板，有緩沖及耐磨作用，不使粉塵直接高速沖擊濾筒，因而能延長濾筒的使用壽命。

? 濾筒 15 0 傾斜抽屜式安裝，可使濾筒拆換更方便，而且除塵器本體內不設置傳動部件，使其維修工作減至少量。對一般性粉塵，濾筒可長期使用不需要更換，省去了常用袋式除塵器需經常換洗濾袋的繁瑣工作，并節省了大量的維修費。

? 先進的壓縮空氣自動定時脈沖清灰，保證除塵器持續低阻力運行。

? 除塵器正面應留出大于 800mm抽筒空間。

Unit Structure  

? The unit adopts advanced down flow type layout and filter cartridge angle mount structure, so the synchro ash removal effect is good in the working process of the filter.

? The dust and gas inlet is equipped with a dust board, which has the function of buffering and wear-resisting, so that the dust cannot directly impact the filter cartridge in high-speed and the service life of the filter cartridge can be prolonged.

? The filter cartridge adopts 150 inclined drawer type installation, so that the cartridge disassembly and change is more convenient, besides, drive disk assembly is not set in the dust removal body, so the maintenance work is reduced to the minimum. For the general dust, the filter cartridge can be used for a long time without replacement, and the tedious work of frequently changing and washing the filter bags of bag filters is left out, and a large amount of maintenance cost is saved.

? Advanced automatic timing pulsating dust-cleaning with compressed air can ensure continuous low resistance operation of the filter.

? The right side of the filter should set aside over 800mm draw tube space.
