1、 What is the impact on the emission standards of filter cartridge dust collectors? The decrease in dust load may come from a decrease in production rate, or from the inspection and adjustment of the control system of the filter cartridge dust collector. The solution is to slowly increase the load with light load or use pre covering dust to solve the problem. Research has shown that excessive filtration speed can increase the dust discharge rate, while excessive filtration and air flushing speed can cause the initial dust layer to break and the dust to impact the filter bag, resulting in excessive wear. If the cleaning frequency of the dust removal filter bag is too high at this time, it can easily cause the fabric of the filter bag to become loose, which can lead to excessive emissions from the dust collector. Setting up a filter cartridge dust collector; When cleaning, it is best to ensure that the filter cartridge dust collector operates at a stable pressure and has a long pulse cleaning cycle. The pulse cleaning time should be set to prevent the initial dust from falling off, and the shorter the cleaning time, the better. If the initial dust layer is insufficient, the cleaning frequency can be extended. If pressure difference control is used, it can improve the stability of the dust collector's inlet and outlet pressure settings. If the excessive emissions of the filter cartridge dust collector only occur after cleaning the filter bag, it is necessary to check whether the compressed air pressure during cleaning is too high. 2、 Maintenance and characteristics of filter cartridge dust collector: 1. The equipment is managed by a dedicated person and inspected every half day during operation. The inspection includes checking whether the pulse meter works normally, whether the solenoid valve can be opened normally, and whether the fan is running normally. 2. The equipment is installed on a concrete foundation on the same horizontal plane, and the equipment assembly and pipeline connection are tightly sealed to prevent air leakage. 3. After the daily operation of the equipment, the dust accumulated in the ash hopper must be discharged by opening the vent valve at the end of the air bag every 72 hours of operation. In addition, for operational efficiency, it is recommended to replace the filter cartridge of the dust collector every 2 years. And before installation, all components should be counted and inspected. If there are any defects or deformations, they must be repaired and repaired before installation. The characteristics of the filter cartridge dust collector: 1. The dust removal efficiency of the surface filtration of the filter cartridge dust collector is much higher than that of the old type dust collector, reducing the emission of substances and achieving world-class air purification indicators, changing the backward state of the old type dust collector that cannot meet the requirements. 2. The volume and weight of the filter cartridge dust collector are much smaller than those of old dust collectors of the same specifications, saving construction space and load, and significantly reducing infrastructure investment. 3. The filter cartridge dust collector has low resistance, consumes less compressed air, and requires no maintenance work. Electromagnetic pulse valves are more energy-efficient than various old dust collectors, saving more than 30% of capital. No enterprise can ignore the significant economic benefits that this energy-saving effect brings to the enterprise. 4. The filter cartridge dust collector has no filter material wear phenomenon, and there are no movable parts on its body. It can be used for a long time without maintenance (even if the filter cartridge is removed and replaced, it is extremely convenient), avoiding the trouble of constantly changing filter materials in old dust collectors, saving money, time, effort, and no secondary pollution. At present, filter cartridges are all used through reverse osmosis membranes, which have a relatively high degree of environmental protection caused by their functional effects. If we want to increase the cleanliness of the surrounding environment and avoid some inconvenience caused by pollution as much as possible through the use of filter cartridge dust collectors, we can choose effective filter cartridges at this time. Such accessory materials can lead to improved working performance. Of course, the working pressure of such dust collectors will also increase. 3、 When selecting a filter cartridge dust collector, attention should be paid to the application environment and the product selection rate. This kind of usage effect will be more obvious. If there is indeed an increase in stress, it is important to give the equipment a timely rest during the cleaning process. This type of operation can also prevent the dust collector from being scrapped prematurely. When choosing to use a dust collector, it should be determined that its environmental condition needs to be improved in terms of cleanliness, so that its cleaning effect can also be increased during the trial use of the dust collector. When conducting research on the use of filter cartridge dust collectors, it is important to pay close attention to their structural design. The reason why this type of dust collector can achieve very good cleaning results using general cleaning methods is because of its filter cartridge device. This type of filter cartridge is difficult to recover and is usually disposable because of its excellent filtering effect. Many dust collectors use this type of filter cartridge to achieve dust removal effect, and can immediately improve the cleanliness of the environment. At the same time, the damage effect on the filter cartridge is also quite significant. We need to pay attention to these details when choosing a filter cartridge dust collector. 4、 The factors that affect the filtration speed of a filter cartridge dust collector include air volume, air speed, and filtration area, which are core parameters. How to choose and match them is a technical task, and only by matching them appropriately can a filter cartridge dust collector suitable for customers be designed. For a filter cartridge dust collector, its filtering air speed is generally only 0.6-0.8m/min, and there is still a significant difference in filtering air speed between it and a bag filter because their filtering materials are different. Why is the filtering wind speed of the filter cartridge dust collector lower than that of the bag filter? What factors are related to the filtering wind speed of the filter cartridge dust collector? The reason why the filtering wind speed of the filter cartridge dust collector is lower than that of the bag filter is mainly because the bag filter uses the base fabric of the bag to filter and remove dust, so the dust removal bag generally requires their weight, and the material is generally not less than 500g/m2, so its filtering wind speed can be faster. The filter cartridge dust collector mainly uses the filter cartridge for surface dust removal, which blocks the dust on the surface of the filter cartridge material, rather than the mesh type dust removal of the bag. Therefore, the filtering wind speed of the filter cartridge dust collector is relatively low. If the filtering wind speed is too fast, it may break through the filtering layer on the surface of the filter cartridge, and the filtering effect of the filter cartridge will not be effective, or the filtering effect will deteriorate. What factors are related to the filtering wind speed of the filter cartridge dust collector? The main concern is still the working conditions, that is, the characteristics of dust. If the dust is very light and has a small particle size, we need to reduce the filtering wind speed of the dust collector and choose a membrane filter cartridge to increase the filtering accuracy. Otherwise, the emission standards cannot be met; If the particle size is larger and the specific gravity is moderate, we can make the filtering wind speed relatively higher. So, the choice of filtering wind speed is mainly related to the characteristics of the dust, which needs to be judged based on experience.
