The pulse blowing bag-type dust collector utilizes the filtering principle to separate solid particles from gas, and a bag is the most key filtering element. When the dust remover works, the smoke to be treated is sucked in by the fan, the dust is intercepted by the cloth bag, and the purified gas is discharged. When the pressure difference reaches a certain level, the system starts a dust cleaning program, and collected dust filter cakes are cleaned from the surface of the cloth bag and fall into a dust hopper below the dust collector by utilizing reverse high-pressure pulse airflow blowing.
Generally speaking, the dust removal effect of simply adopting reverse high-pressure pulse airflow for blowing is not ideal. Therefore, the industry improves the method, a vibrating device is arranged at the bottom of the cloth bag so as to supplement and optimize the reverse high-voltage pulse, and the working principle of the method is as follows: the cloth bag is beaten by beating and hammering, the cloth bag is vibrated up and down and shaken left and right, and dust filter cakes on the cloth bag fall off from the surface of the cloth bag. However, even if the dust removal effect is not ideal by adopting the blowing and vibration modes, because the cloth bag adsorbs more static electricity, the static electricity is the main reason for adsorbing dust, most of dust can only be treated by adopting the blowing and vibration modes, all the dust cannot be treated, and the rest dust still depends on the static electricity to be tightly attached to the cloth bag, so that the dust removal device in the aging experiment box is provided to solve the defects in the prior art.
