The operation of the bag filter can be divided into a trial operation period and a daily operation period. Pay attention to the impact of changes in the load on the host equipment on the performance of the precipitator. After the machine is started, pay close attention to the working condition of the bag filter and make relevant records. In daily operation, the necessary inspections should still be carried out, especially the inspection of the performance of the bag filter. In the trial run of...
In the daily operation of the bag filter, some changes will occur due to operating conditions, or some faults will affect the normal operation and working performance of the equipment. Regular inspections and appropriate adjustments are required to extend the equipment. The life of the filter bag reduces power consumption and recycles useful materials. The issues that should be noted are: 1. Operation record Each ventilation and dust removal system must be installed and equipped with the...
The bag filter can be divided into three modes: upper inlet, lower inlet and side inlet according to the air inlet mode. First, the way of entering the wind The dust-containing gas enters from above the filter bag and the lower part is discharged. The direction of dust deposition in dusty flue gas is the same as that of flue gas. The upper air bag filter has better effect in treating aerosols with more ultrafine dust (<3μm), and the resistance of the equipment is smaller, but more Block...
The pulse jet bag filter is used to periodically blow the filter bag with compressed air to remove soot deposited outside the filter bag. When blowing, an instantaneous negative pressure is formed in the venturi tube region, and a large amount of surrounding gas is drawn into the filter bag, so that the dust particles attached to the outside of the filter bag fall into the dust collecting hopper.
1. What is the filtering wind speed: The filtering wind speed is an important technical and economic indicator reflecting the ability of the bag filter to process gas. It has a great influence on the work and performance of the bag filter. 2. Influence of wind speed on equipment: When the filtering wind speed is high, the filtration area and volume can be reduced, the floor space can be reduced, and the investment can be reduced. However, the high selection of filtration wind speed will affect...
First. According to related manufacturers, in the 1950s, the original Soviet-type products were mainly used. In the 1960s, there were a few design research units in China that modeled the pulse type of the United States, Japan, and other countries. Based on the bag type dust collector, the production of its own products began. Phase 2. After 1973, a number of bag filter manufacturers began to appear in China. In the 1980s, some design institutes, research institutes and universities were...
Experience in transforming kiln head electrostatic precipitator into bag filter 1. System calibration and program analysis Inviting relevant qualified manufacturers to calibrate the kiln head system to understand the current system resistance, actual air volume and other related parameters, and then provide a basis for the bag filter modification and the existing kiln head exhaust fan changes. The calibration parameters of the dust removal system before transformation are shown in Table 1. The...
In the normal working operation of the bag filter, due to the sealing of the equipment and the selection of the wind speed, the dust removal equipment will not be completely treated, which will cause the dust to leak out, which will affect the normal operation of the whole set of equipment and make the discharge of the equipment not meet the standard. The construction experience has found problems and solutions to facilitate users to find corrections in the future. Analysis of the causes of...
Multi-bag filter cartridge maintenance method When the filter cartridge is used to meet the design flow rate (the pressure gauge difference is 0.1 MPa before and after the flow rate drops significantly), please turn off the filter from the filter, remove the filter cartridge from the filter, rinse the surface with water, and then first Soak in 4% hydrochloric acid for 24 hours, then soak in 4% sodium hydroxide for 24 hours, then rinse with water (two O-rings are removed during soaking to...

Introduction: The bag dust collector is currently the most widely used dust removal equipment in the dust removal industry. In some special industries, dust and some dust are flammable and explosive. Therefore, we need to perform special treatment on the bag filter to achieve the purpose of fire prevention and explosion protection. 1. If the gas to be treated is high-temperature gas, use a high-temperature, non-flammable dust filter bag. 2. When dealing with flammable and explosive dust, dust...
In many fields, filtration equipment plays an important role. Among them, the stainless steel bag filter is a new type of filter on the market. Its cylinder is made of stainless steel. The entire stainless steel bag filter includes the filter container, the support basket and the filter bag. It is understood that the biggest difference between the filter and the microporous membrane filter used in the past is that the liquid flows from the filter bag to the outside of the bag, and the filtered...
The following article on "improving the efficiency of the glass factory dmc-96 pulse bag filter is timely inspection and cleaning ash" article The efficiency of the bag filter mainly depends on the thickness of the dust layer on the filter bag. After the dust layer is formed, it becomes the main filter layer, and the filter bag just plays the role of forming a dust layer and supporting its skeleton. As the dust accumulates on the filter bag, the thickness of the dust layer increases, and the...
