Application effect of dust removal skeleton: The carbon steel used in the dust removal skeleton is welded and formed in one step, which supports the dust removal bag. After surface treatment such as spraying and galvanizing, the performance is enhanced. The dust removal skeleton belongs to the raised type, so during transportation, compression may cause deformation of the dust removal skeleton. Once the dust removal skeleton deforms, it cannot provide good support anymore. The majority of the dust removal skeleton will be slightly deformed by the loading and fastening forces, which is a necessary problem for products with bare dust removal skeleton. Dust removal frame, also known as dust removal bag cage, is an accessory of bag filter, used as a frame to support the dust removal filter bag. It can be compatible with six, eight, ten, twelve, sixteen, eighteen, twenty, and twenty-four ribs. The role of dust removal frame is very important and it is widely used in the dust removal industry, chemical industry, and other industrial places. The resistance of the dust removal skeleton increases with the addition of the thickness of the dust layer on the outer surface of the filter material. Clean the dust when the resistance reaches a certain rule value. At this time, the PLC sequentially controls the opening and closing of the pulse valve, closes the lifting valve in one compartment, cuts off the filtered airflow, and then opens the electromagnetic pulse valve. The compressed air rapidly expands in the upper box and rushes into the filter cartridge, causing the filter cartridge to expand, deform, and vibrate. Under the effect of reverse airflow flushing, the dust attached to the surface of the filter bag is peeled off and falls into the ash hopper. After the dust cleaning is completed, the electromagnetic pulse valve is closed, the lifting valve is opened, and the chamber returns to the filtering mode. The cleaning of each room is carried out sequentially, with one cleaning cycle starting from the beginning of the room cleaning and ending at the beginning of the next cleaning. The scattered dust falls into the ash hopper and is discharged through the ash removal valve. The installation of filter cartridges in the dust removal framework is very important. They can be vertically installed on the box flower board or tilted and installed on the flower board. From the results of dust removal, vertical installation is more reasonable. The lower part of the flower board is the filtering chamber, and the upper part is the pulse chamber of the air box. An airflow dispersing plate is installed at the dust removal framework. The dust removal skeleton is the rib of the filter bag, and the quality of the dust removal skeleton directly affects the working condition and service life of the filter bag. The processing air volume of the dust removal skeleton is large, the load adaptability is strong, the ceramic movement is smooth, there will be no blockage, the footprint is small, and it can be flexibly installed according to the user's site conditions, and can be placed indoors or outdoors. The dust removal framework is easy to install and requires minimal maintenance. To prevent condensation, the temperature of the gas in the dust removal framework and its system should be kept 25-35 ℃ higher than its dew point (such as the dew point temperature of 58 ℃ for kiln mill integrated machines, and the operating temperature should be above 90 ℃), in order to achieve good performance of the filter bag. After the dusty gas enters the dust removal skeleton ash hopper, due to the sudden expansion of the airflow cross-section and the effect of the airflow dispersion plate, a local coarse particle in the dust removal skeleton airflow settles in the ash hopper under the action of dynamic and inertial forces; After the dust particles with fine particle size and low density enter the dust filter chamber, they undergo a combination of Brownian dispersion and screening effects, causing the dust to accumulate on the surface of the filter material. The purified gas enters the clean air chamber and is discharged through the exhaust pipe and fan. There are two methods for cleaning dust in traditional filter cartridge dust removal frameworks: high-pressure air flow back blowing and pulse air flow blowing. Theory suggests that the former has the advantage of average air flow, but the disadvantage is high wool consumption; The advantage of the latter is that it consumes less air, while the defect of the dust removal skeleton is the small airflow. The dust removal framework can be improved in two aspects: on the one hand, a guide installation can be added to the pulse jet pipe to enhance the airflow induction effect, and on the other hand, the upper guide duct of the filter cartridge can be eliminated to allow the pulse airflow and induced airflow to enter the filter cartridge sufficiently. After the improvement, the air consumption is reduced, the airflow is evenly distributed, and the dust cleaning results are good. According to calculations, the dust removal skeleton skill has been improved, and the dust cleaning airflow flow rate is 3-5 times that of the pulse airflow. The airflow dispersion of the filter cartridge dust removal skeleton is very important. Consider how to prevent the formation of high wear areas on the filter material at the equipment due to high wind speed. The airflow dispersion plate has common requirements for the filter cartridge dust removal framework, and the airflow dispersion is very constant and even. It is beneficial for the increase of airflow and the decrease of dust, and the opening rate of the airflow dispersion plate is 35%. According to calculations, the resistance coefficient is less than 2, indicating that the porous airflow dispersion plate can meet the requirements of the filter cartridge dust removal framework when the airflow velocity is less than 0.8m/s. Attention should be paid to the transportation of dust removal skeleton: During the transportation of dust removal skeleton, it belongs to floating cargo, with light weight but occupying a large space. Therefore, the transportation cost of dust removal skeleton cannot be calculated by weight, but should be calculated by cubic meter. The volume of the dust removal skeleton is the object of accounting for the transportation cost of the dust removal skeleton. The local deformation of the dust removal skeleton, as long as welding is not opened and the local deformation is manually straightened, will not affect normal use, and generally will not cause damage to the external galvanizing of the dust removal skeleton. The dust removal skeleton belongs to the heart part of the bag filter, and its quality plays a decisive role in the normal operation of the bag filter. These are well-known, and most customers have recognized this and paid considerable attention to the selection of dust removal skeleton. However, most people only pay attention to the material selection of the dust removal skeleton, and ignore the transportation problem of the dust removal skeleton. Therefore, the transportation process of the dust removal skeleton is also highly valued. A good dust removal skeleton should be carefully considered at almost every step from material selection and production to successful installation. As the saying goes, details defeat the whole picture. Perhaps a seemingly small link can lead to the failure of the entire system, and we should pay extra attention to it. The dust removal framework can also be welded to the external frame body according to customer needs, so that the dust removal framework can be lifted as a whole during transportation and loading and unloading, and the dust removal framework as a whole is not damaged, which can meet customer needs.
