Embodiment 1

[0012] Embodiment 1: with reference to attached Figure 1-3 . Pulse blowback air purification equipment, which includes a chassis 1-1, fan assembly 1-2 and ash collection drawer 1-4, the fan assembly 1-2 is fixed in the chassis 1-1 through the fan pressure plate 1-5, and the pulse rotates to clean the dust The component 1-3 is located under the fan pressure plate 1-5 and is connected with the chassis type 1-1. The triangular positioning frame 14 in the pulse rotation cleaning component is fixed on the hole of the orifice plate through bolts 13, nuts 14 and gaskets 15. Around, the off-line dust cleaning cover 15 covers the hole of the orifice plate and is located in the triangular positioning frame 14, the upper end of the gas sleeve 12 is connected with the upper end plate of the triangular positioning frame 14, and the piston 13 is located in the gas sleeve 12 and under the action of the gas under pressure Moving up and down along the inner wall of the air sleeve, the upper ...

Embodiment 2

[0016] Embodiment 2: On the basis of embodiment 1, the self-cleaning method of pulse blowback air purification equipment, it comprises air purification equipment, when it comprises the filter cartridge 20 inner wall in the air purification dedusting equipment needs to regenerate, band compressed air The source supplies air to the air bag 2, opens the pulse solenoid valve 1, and the pulsed air flow with pressure enters the piston 13 through the air guide pipe 6 and 8, and then enters the spraying rotary frame 19 through the piston all the way, and passes through the piston rod on the upper part of the piston plug ring all the way. The air hole 13-3 enters the air cavity formed by the upper part of the piston plug ring 13-1 and the air sleeve 12 and forces the piston 13 to move up and down according to the pulse air flow. The swivel frame 19 rotates under the action of the airflow while cleaning the dust, so as to achieve the purpose of regeneration of the filter cartridge.
