CNMC countercurrent pulse back blowing bag filter
CNMC countercurrent pulse back blowing bag filter, also known as filter filter, is a dry filter that uses bag filter elements made of fiber woven fabric to capture solid particles in dusty gas. Its action principle is that when the dust particles bypass the filter cloth fiber, they are intercepted due to the collision between inertial force and fiber. Fine dust particles (with particle size of 1lm or small) constantly change the direction of motion by the impact of gas molecules (Brownian motion). Because the gap between fibers is smaller than the free path of Brownian motion of gas molecules, dust particles collide and separate from fibers. Its working process is related to the weaving method of filter material, fiber density, dust diffusion, inertia, shielding, gravity and static electricity and its dust removal method. Filter cloth material is the key filter cloth of bag vacuum cleaner. In addition to specific density and ventilation performance, it also needs good performance. Fibers with good heat resistance, mechanical strength and heat resistance have now reached 250 ~ 350 ℃
CNMC countercurrent pulse back blowing bag filter can be divided into vibration type, gas ring back blowing type, pulse type, acoustic type and composite type according to different dust removal methods. According to the reflected air pressure, the pulse reflection type can be divided into high-pressure pulse reflection type and low-pressure pulse reflection type. Pulse back blowing bag filter is a widely used dust removal device in the world, because its pulse injection intensity and frequency can be adjusted and the dust removal effect is good. After the dusty gas enters from the inlet of the bag filter, it enters each unit room through the guide pipe. Under the action of the diversion device, the large particle dust directly falls into the ash hopper after separation, and the rest of the dust evenly enters the filtering area of each bin with the air flow. The filtered clean gas passes through the box, poppet and exhaust pipe through the filter bag. With the progress of filtration, when the dust on the surface of the filter bag reaches the thickness, the dust control device (differential pressure or periodic). Manual control) closes the rising valve according to the set procedure, controls the current unit offline, opens the electromagnetic pulse valve and blows away the dust in the filter bag. The dust falling into the ash hopper is discharged through the ash discharge valve and sent out by the ash conveying system
characteristics of CNMC countercurrent pulse back blowing bag filter:
1. CNMC countercurrent pulse back blowing bag filter adopts pulse back blowing dust removal mode, which is a good dust removal effect in China at present. The upper box of the equipment is divided into 18 interconnected small rooms, which are connected with the long text tube, and the purpose of dust removal is achieved through program control pulse. The structure cancels the small writing tube on the upper end of the spray pipe and the filter bag, and has simple structure and convenient operation and maintenance. p>
2. Compared with other domestic vacuum cleaners, the equipment has the characteristics of large air volume and small system resistance, and has a wide range of application
3. Press the flower plate edge of the upper and middle box into a conical hole to form a smooth surface contact with the filter bag, seal < span style = "" > powerful
, and reduce the wear between the hole edge and the filter bag4. Simple and reasonable structure, small floor area, and can be installed indoors and outdoors. Users can handle the air volume, free model or parallel combination according to the production process, and provide carbon steel or stainless steel vacuum cleaners as needed
