Method for cleaning filter bag for cloth-bag or electric-bag dust collector
A dust collector and filter bag technology, which is applied in the cleaning field of filter bags for cloth bags or electric bag dust collectors, can solve the problems affecting the service life of filter bags, the stable operation of dust collectors, the increase of dust removal resistance/pressure difference of filter bags, and the surface area of filter bags. Too much dust and other problems, to shorten the cleaning cycle, reduce energy consumption, and restore the effect of air permeability

Embodiment 1
[0016] A method for cleaning a filter bag for a cloth bag or an electric bag filter, comprising the following steps:
[0017] ① Cut out old filter bags of suitable size for fracture strength test (test method adopts GB / T3923.1-1997), the results are shown in Table 1. It can be seen from Table 1 that the radial and latitudinal fracture strengths are not less than 400N, then The next test step can be carried out.
[0018]
[0019] ②Cut 100cm 2 The sample of the above-mentioned filter bag was cleaned with a vacuum cleaner until there was no obvious dust on the surface, then soaked in 250ml of water, and the pH value and ion concentration of the soaking solution were measured (the ion concentration was measured by plasma emission spectrometer-ICP). The results are shown in Table 2. From the analysis results, it can be seen that, except for Cl - In addition, if all other components are out of the specified range, it is determined that the filter bag needs to be cleaned. The p...
Embodiment 2
[0025] A method for cleaning a filter bag for a cloth bag or an electric bag filter, comprising the following steps:
[0026] ①Intercept old filter bags of suitable size for fracture strength test (test method adopts GB / T3923.1-1997), the results are shown in Table 4, it can be seen from Table 4 that the radial and latitudinal fracture strengths are not less than 400N, then The next test step can be carried out.
[0027]
[0028] ②Cut 50cm 2 The sample of the above-mentioned filter bag was cleaned with a vacuum cleaner until there was no obvious dust on the surface, then soaked in 125ml of water, and the pH value and ion concentration of the soaking solution were measured (the ion concentration was tested by plasma emission spectrometer-ICP). The results are shown in Table 5. From the analysis results, it can be seen that, except for Cl - In addition, if all other components are out of the specified range, it is determined that the filter bag needs to be cleaned. The pH ...
