Bag dust collector is a very important equipment in the field of industrial environmental protection, mainly used to purify industrial dust emissions. And its cleaning cycle is one of the important factors that determine its operating efficiency and service life. So how to determine the cleaning cycle of the bag dust collector?

First of all, the determination of the cleaning cycle should start from the operating principle of the bag dust collector. Bag dust collector by trapping industrial dust, so that the air after the filter bag left dust to achieve the purpose of purifying the air. However, over time, the blockage naturally occurs, resulting in a decrease in filtration efficiency, an increase in operating resistance, and ultimately an inability of the dust collector to operate. Therefore, the key to determining the cleaning cycle is to avoid excessive dust capture of the cloth bag and maintain its filtration performance.

In general, the length of the cleaning cycle is related to operating conditions, filter bag material, bag dust collector structure and other factors. Here are some specific aspects:

1. Operating conditions

Operating conditions refer to temperature, humidity, particle size of dust-containing gas, adhesion, etc., which will also affect the selection of cleaning cycle. For example, the ambient temperature is too low will affect the chemical reaction and dust removal efficiency, while the high temperature is easy to make the filter material aging and deformation; Humidity can lead to deterioration of filter materials; And the ultrafine dust will produce static electricity and adsorption, easy to block the filter material and so on. These factors will lead to the increase of the operating resistance of the bag dust collector, accelerate the aging and damage of the filter material, so it is necessary to monitor and appropriate control in actual operation to extend the cleaning cycle.

Second, filter bag material

The choice of filter bag material is also one of the important factors affecting the cleaning cycle. Different materials have different filtration properties, such as needle felt, glass fiber cloth and other capillary effect is strong, can filter sticky dust; And polyester and other fiber materials are more heat resistant, corrosion resistant, can be used in high temperature, corrosion and other harsh environments. In addition, the specifications and quantity of filter bags should also be reasonably selected according to the actual situation.

Three, bag dust collector structure

The structure of the bag dust collector will also directly affect the cleaning cycle. In the bag dust collector, there is often a spray cleaning system, that is, while cleaning the bag through the operation, a certain amount of air is put in to cause the vibration of the filter bag to remove too much dust. Different dust collector structure, the use of jet cleaning system will also be different, will affect the length of cleaning cycle.

Based on the above aspects, we can determine the method of cleaning cycle:

First, conduct an experiment. A certain amount of dust can be collected and monitored under different operating conditions to obtain the basic data of the cleaning cycle. At the same time, it is also possible to find a better cleaning cycle by constantly testing, changing the filter bag material, structure and jet cleaning system.

The second step is to test. According to the data obtained from the experiment, the operation resistance and dust removal efficiency are tested, and the accuracy of the cleaning cycle is judged. If the cleaning period is too long, it will accelerate the aging and damage of the filter material; If the cycle is too short, it will not only lose the effect of purifying the air, but also lead to the waste of energy. Therefore, it is very important to choose a suitable cleaning period.

The third step is to optimize the cleaning method. On the basis of determining the cleaning cycle, it can be adjusted and optimized according to the actual situation and experience to achieve better dust removal effect and energy saving and emission reduction.

In short, the dust cleaning cycle is one of the key factors affecting the operation effect and service life of the bag dust collector, which requires multi-faceted research of experiments and tests to gradually explore a good solution and optimize. Only on the basis of multiple tests according to the actual situation, can a suitable cleaning cycle be obtained to ensure the normal operation of the filter bag and achieve the purpose of purifying the air.
