Bag dust collectors often have some problems in the actual use process, which not only affects the use effect, but also increases the maintenance cost and even affects the normal production of cement enterprises. This paper proposes corresponding solutions to the problems existing in the application of bag filter in cement plant. 1.1 problems 1) After the factory has eliminated the wet rotary kiln, it is planned to change the Φ3.0m×12m raw material mill to the open road high-fine cement mill....
The main working principle of the bag filter is that the bag captures a dust collector that filters the dust particles that are collided by inertia to achieve the filtering effect. Bag filter should pay attention to many factors when choosing. Below we will introduce you how to judge the quality of the bag filter. The main working principle of the bag filter is that the bag captures a dust collector that filters the dust particles that are collided by inertia to achieve the filtering effect....
1. Bag filter designer is the protagonist of electromagnetic pulse valve selection Cleaning is an important measure to ensure the normal operation of the bag filter. If the blowing performance and volume of the pulse valve can not effectively remove the dust cake formed on the dusty surface of the filter bag, the resistance of the dust collector (inlet and outlet pressure difference) will be caused. Ascending, the negative pressure of the dust source collection port decreases, and the treatment...
According to the actual working conditions, the top and bottom of the filter cartridge can be made of rubber or carbon steel. The PulesPleat filter usually adopts 45 pleats. Of course, it can be redesigned according to specific needs. The standard pleated filter cartridge can be used up to 1300 °C. The special ThermoPleatTM has a maximum operating temperature of 2320 °C. The length and diameter of the filter cartridge are also varied to provide the correct filtration area, and there are many...
Bag dust collectors are not very strange to us. We must use bag filters in some production industries, because we must ensure the cleanliness of our working environment. Then we will introduce you to the specific process of bag filter: First, the working process of the bag filter: The bag filter is also called a filter type dust collector (bag type dust collector). It is a dust removal device that uses bag filter elements made of fiber braid to capture solid particles in dusty gas. The...
How to choose the correct bag filter? This article briefly summarizes the development history and technological innovation of bag filters, and points out the advantages and disadvantages of different types of filters. Effective selection of filters can help optimize process operation and reduce maintenance costs.

I. Introduction The inside of the filter is supported by a metal inner mesh. The liquid flows in from the inlet, passes through the filter bag and flows out, and the impurities are intercepted in the filter bag Second, the installation 1. First, please confirm that the accessories required to install the bag filter system are ready: 1 bag filter body 2 Ο type seal ring 3 metal inner net 4 filter bag 5 pressure gauge two (optional) 2. Check the seal ring and the Ο-shaped groove on the filter...
No matter what kind of powder is produced, the color of the powder in the bag filter is different from the color of the powder in the tower. For example, the powder in the milk powder production tower is light yellow, and the powder in the bag filter is grayish white. In the production of tea powder, the powder in the tower is brownish yellow for green tea, and the yellowish green in the bag filter (green in the yellow) is lighter than the color of the powder in the tower. The main reason is...
Working principle The dust-containing gas enters the bag filter from the air inlet pipe of the bag filter. After the uniform air action in the large space, the filter bag is evenly inserted. The material is trapped by the filter bag and deposited on the outer wall of the filter bag. The filtered clean gas After the venturi tube enters the upper tank, it is discharged from the exhaust pipe. The bag filter is equipped with an electromagnetic pulse valve, and the pulse valve is periodically...
The superfine surface needle felt has a very good effect of cleaning dust compared with the ordinary needle felt. In actual use, the system resistance rise is also much slower than that of the ordinary needle felt. This is because the microfiber has Larger specific surface area and smaller fiber gap, which can achieve better filtration effect and filtration efficiency than ordinary filter materials, and is more suitable for the requirements of powder collection in coal injection system. The...
With the increasing advancement of production technology, screw conveyors have also been used more and more widely, but due to people's inattention or lack of common sense, there are always some accidents of one kind or another. a. Before using the screw conveyor, check whether the running parts, the tape buckle and the carrying device are normal, and whether the protective equipment is complete. The tension of the tape must be adjusted to an appropriate level before starting. b. The fixed...
The so-called single machine test is that when the dust collector selects the pneumatic power control valve, the staff must first turn on the compressed air, check the tightness of the air circuit system, check whether the pneumatic components can work normally ; the ash conveying system is energized and tested, and the inspection is normal. For the work, when using the blower fan, power on the fan and test the car. After working normally, turn off the blower. Simulated no-load test: Firstly,...
The operation of the bag can be divided into trial operation and daily operation. The dust bag should be done for those inspections. 1. When the bag filter is in trial operation, it is necessary to inspect the single part of the system, and then perform adaptive operation, and perform some performance tests. In daily operation, necessary inspections should be carried out, especially for the dust collector bag. Check the performance. Pay attention to the impact of changes in the load on the host...
First, equipped with mill water spray mill, to ensure good atomization. Stop the water a quarter of an hour before stopping grinding. Avoiding the evaporating of moisture evaporates the filter bag. Second, filter bag cleaning wind pressure to maintain more than 0.5MPa, require oil and water separation, air bag should be timely release of water. Always inspect the interior of the baghouse to open and close the air duct, and control the sweeping air. Check the degree of clogging of the filter bag...

Causes of bag failure of biomass boiler dust collector 1. Dust collector clogging Because the amount of ash carried by the flue gas greatly exceeds the design value, a large amount of dust particles are attached to the cloth bag. Cloth bag dust collector is blocked for a long time, which increases the bag end difference, especially when the ash content and humidity are high. 2. When the injection pressure starts the injection, a large pressure is generated in the bag. When the bag of the dust...
