How does a bag filter filter flue dust? When most of the dust bag is found to be damaged, it should be completely replaced. It is best to replace the dust bag when the vacuum cleaner stops working. At this time, the pulse controller should be closed and the top manhole door should be removed to remove the bag. When removing the dust, first remove the dust removal frame. Then pinch the spring ring on the top of the bag into a concave shape and pull the dust bag up. Before installing a new bag, you should remove the dust from the hole in the faceplate. When you find out the cause of the dust generated by the bag filter, you can use the air outlet The number of digits corresponding to the electromagnetic pulse valve and the pulse controller when the dust is in the dust, to determine which dust bag is removed from the leak. The bag filter with the cover removed can also use a flashlight to find the dust bag with the leak in the upper observation hole of the box. Or open the upper cover, and then open the pulse controller. During the blowing process, it was found that the dust ejected from the venturi tube was a dust bag that leaked dust. Then, address the issues that arise. Because most of the dust bag should be completely replaced when it is damaged. It is best to replace the dust bag when the vacuum cleaner stops working. At this time, you should turn off the pulse controller and open the top manhole door to take out the bag. When removing the dust, first remove the dust removal frame. Then pinch the spring loop on the top of the bag into a concave shape and pull the dust bag up. Before installing a new bag, you should remove the dust from the hole in the faceplate. When replacing the dust bag with a bag filter, check and analyze the cause of the damage.
How the bag filter filters flue gas and dust The factors that affect the service life of the dust bag include the nature of the dust, air distribution, processing quality of the dust removal frame, etc. If the bag holder is not welded firmly, the dust bag should be punctured during use, and the dust holder should be welded in time. The burr and welding slag of the dedusting rack are polished, or a new dedusting rack is replaced. The framework of the dust bag is usually welded with 4mm diameter steel wire. There are two common welding methods, one is spot welding with a spot welder, and the other is oxyacetylene welding. The above method has the advantages of high production efficiency, smooth surface, hard to produce burrs, and small deformation. The vacuum cleaner cannot work with the damaged dust bag, otherwise it will accelerate the scrapping of the cleaner. In order to save the cost of some dust bags when they are damaged in a small area, it is recommended to use old bags or new filter cloths of the same material for filling. The method of filling the holes is to use a silicone rubber mixture for bonding, as long as the temperature and chemical properties of the adhesive are used. Adapt to process conditions. The latter method has low production efficiency, rough surface and easy deformation. In addition, some use plastic frames, but such frames are not suitable for use at high temperatures. During the blowing process, because the dust bag is rubbed against the outer surface of the dust removal frame every time it is cleaned, although the dust bag is not damaged after a period of use, the inner surface of the dust bag is in abrasion with the dust removal frame. When refilling The original parts can be staggered according to the wear marks to avoid continuous wear in place and prolong the service life of the dust bag.
How to filter flue dust with bag filter 袋式除尘器处理烟气粉尘 火星烟尘，为防止火星进入袋式除尘器，应采取以下措施: 设有预除尘器和冷却管道， 布袋除尘器前设置旋风除尘器或惰性除尘器作为预除尘器，捕集粗尘和火星.这样太好的火星不容易被抓到. 在大多数情况下，颗粒灰尘会在进入吸尘器之前燃烧掉. 前置除尘器后设置. 放置冷却管并控制管内流速，使其尽可能低.。 The bag type dust collector handles the flue gas dust and Mars soot. In order to prevent Mars from entering the bag type dust collector, the following measures should be taken: a pre-dust collector and cooling pipes are provided, and a cyclone or inert dust collector is set as a pre-dust before the bag duster. It catches coarse dust and Mars. Such a good Mars is not easy to be caught. In most cases, particulate dust will burn out before entering the vacuum cleaner. Set after the front dust collector. Place the cooling tube and control the flow rate in the tube To keep it as low as possible ... This is a relatively reliable technical measure. It can make the gas have sufficient residence time in the pipeline. It is equipped with a cooling spray tower. Direct water spray in advance. Gas cooling. Law. To ensure the safe fire protection of dust-containing gas in the dust collector, control and supply the amount of cooling water. Most of the burning dust. After contact with fine water droplets. Cool, but the water droplets are easy to vaporize. In order to cool the combustion dust that has not touched the water droplets, there should be Necessary space .. and dwell time. In special cases, spray towers, cooling pipes and pre-dusters are used. Combined to prevent Mars from mixing in, more thoroughly set Mars capture device. Installed on the pipeline. Mars capture device is a An easy way. At the same time, a Mars alarm is installed, which can make Mars send out an electric signal alarm when passing the trap. At the same time, stop operation or change the gas path, etc.
