Knowledge!How to measure the quality of bag dust collector?

The dust removal efficiency is the most basic parameter to measure a piece of equipment. The dust removal efficiency indicates the ability of the bag dust collector to handle dust-containing gases. It is directly related to the bag dust removal rate.

When selecting equipment, choosing a suitable dust collector is often the most concerned issue for manufacturers. Below, ZIBO Decent will help you solve your concerns about bag dust collector selection. I hope it will be helpful to you.

The first step: Master the dust removal working conditions and determine the physical and chemical properties of smoke dust.

How to choose a bag dust collector? We need to understand the composition of the dust-containing gas, as well as the temperature, whether there is corrosion, whether it is flammable and explosive, etc.; we need to look at the particle size, dispersion, grindability and viscosity of the dust; and also It is necessary to learn from the bag dust collector manufacturer about the relevant dust collector air volume, wind pressure, service life, installation requirements and other basic information; finally, it is necessary to pay attention to whether the flue gas concentration after filtering by this bag dust collector unit can reach relevant standards.

Step 2: Determine the dust cleaning method and select the dust collector model

We all know that bag dust collectors can be divided into four categories according to the dust cleaning methods: mechanical vibration type, pulse injection type, reverse blowing type and compound dust cleaning.

Step 3: The selection of filter material is related to the life of the filter bag

One factor of dust removal efficiency is closely related to the dust collector filter bag filter material. When selecting, the physical and chemical properties of the dust-containing gas and the dust cleaning method of the selected equipment should be taken into consideration as much as possible. Nowadays, there are many types of filter materials. There are needle felt, laminate, woven and fiberglass, etc. The correct choice will bring convenience to future maintenance.

Step 4: Determine the filtration wind speed based on experience

When determining the filtration wind speed of the dust collector, factors such as the characteristics of the dust, the type of filter material, and the method of dust cleaning must be taken into consideration. If the filtration wind speed is selected, it will handle fine particles and sticky particles. Grinding stone dust will be detrimental, and for gases with high temperature and high humidity, the dust filtering wind speed should not be too large. For some filter materials with slightly larger resistance, the filtration wind speed can be appropriately larger, which also needs to be determined according to the type of filter material.

Step 5: Calculate the filter area of the dust collector

Generally speaking, when calculating the filtration area of a dust collector, you need to know the air volume processed and the filtration wind speed. This must be calculated by engineers with many years of dust removal experience.

Step 6: The cleaning cycle is determined according to the actual situation

Due to the influence of various factors such as the cleaning method of the dust collector, the characteristics of the smoke and dust, the type of filter material, the filtration wind speed and pressure loss, the dust removal and cleaning cycle needs to be fine-tuned by relevant personnel to grasp the injection cycle and pulse interval.

The first choice for choosing a suitable bag dust collector is the working conditions. After understanding the nature of the dust, then determine the cleaning method, selection of filter materials, filtering wind speed, filter area, cleaning cycle, and finally determine the model of the dust removal equipment. .
