The principle adhered to in the production of pulse bag dust collectors is: 1. Standardization principle for the production of pulse bag dust collectors: The dust collector is produced according to the design drawings and relevant standards and specifications, and the components are disassembled, manufactured, and inspected, and numbered before leaving the factory. 2. The principle of factory production for pulse bag dust collectors: all dust collector production is controlled to be prefabricated in the factory, and all components are completed in the factory according to the procedures and methods specified in the design drawings. 3. The programming principle for the production of pulse bag dust collectors: The production of dust collectors is carried out in accordance with the equipment installation program, and the sequence of production, storage, factory delivery, and transportation is organized and constructed. Namely, bracket, ash hopper, upper box body, maintenance door, pulse ash cleaning facility, ash conveying facility, ash silo, ladder guardrail, pipeline dust hood, and electrical. 4. The principle of transportation for pulse bag dust collectors: After the dust collector is manufactured, the packaging form and transportation method should be determined according to its component characteristics to prevent distortion, deformation or other injuries during the transportation process, and achieve the transportation of components. 5. The principle of integrated installation of pulse bag filter: The prefabricated dust collector should provide original conditions for the installation of equipment in separate combinations. Strictly ensure the accuracy of the actual sample size, achieve component prefabrication: flexible separation, convenient size and combination, and accurate processing. Important components should undergo pre installation approval before leaving the factory. The entire working process of the pulse bag filter for ash discharge: 1. The ash discharge system of the bag filter works normally and needs to maintain good sealing to avoid air leakage, which may result in substandard dust removal efficiency. 2. When choosing an ash discharge device, it is necessary to understand the state of the discharged dust (dry powder or slurry), the ash discharge system (intermittent or continuous), the nature of the dust, the amount of dust discharged, and the pressure condition at the dust outlet of the dust collector. 3. There should be a high ash column above the ash discharge device to form an ash seal and ensure airtightness at the dust outlet of the dust collector. 4. The dust discharge capacity of the ash removal device should be less than the capacity of the transportation equipment. When using mixing or blending equipment to humidify the dry powder dust discharged from the dust collector, a dust discharge device that can uniformly and quantitatively feed should be selected, such as a rotary unloader, ash discharge valve, screw conveyor, etc. 5. Dust removal devices that rely on the principle of leverage, such as flash dust removal valves and flip dust removal valves, should be installed vertically and adjusted in a timely manner. Design skills for the inlet duct of pulse bag filter: When choosing a pulse bag filter, we need to know the design method of the duct before designing the air volume and speed of the dust removal equipment. Whether the dust removal system can operate normally is also closely related to the duct design. The cross-sectional shape of the duct can be divided into circular and rectangular shapes. Circular ducts have a smaller diameter and are easier to make, which is also convenient for future insulation work. However, the drawing and processing of the pipe fittings in the manufacturing process are more complex than those in rectangular ducts, so there are technical requirements for sheet metal work. When the diameter of the pipe is small and the flow velocity inside the pipe is high, circular pipes are mostly used. However, when transporting high-temperature flue gas or when the installation position is limited, rectangular pipes are also widely used. A good detailed design plan for the pipeline of a bag filter: The pipeline layout should be as simple as possible, designed to be vertical at 90 ° or inclined as much as possible, with an inclination angle of not less than 45 °, so that the accumulated dust inside the pipeline can naturally fall off. The pipeline generally adopts a circular cross-section because square and rectangular cross-section pipelines are prone to dust accumulation. Precautions for using a pulse bag dust collector: There are many advantages to using a pulse bag dust collector. However, when using this type of dust collector, it also has its own limitations. Using this cleaning equipment cannot solve all the problems of dust, and it cannot have all the advantages in dust control. The problems to be noted when using this type of dust collector are: 1. Some flue gas contains a lot of moisture, or the dust carried by it has strong moisture absorption. Therefore, when using a dust collector for cleaning and hygiene, it often leads to the phenomenon of the filter bag of the pulse bag dust collector sticking and blocking the filter material; In order for this type of dust collector to work normally in humid environments, drying or insulation measures should be taken during its operation. During the operation of the dust collector, the moisture in the gas will not condense together and affect its operation. 2. The filter bag of the dust collector has the ability to withstand temperature. When purifying high-temperature flue gas, sufficient measures should be taken to reduce the temperature of the flue gas. 3. The filter material of the pulse bag dust collector is cotton spinning or fiberglass, which can affect the cleaning effect when filtering short fiber dust. This is something to be aware of. When using a bag filter, only by paying attention to these issues can this cleaning tool play its full role.
