Problems solved by technology

[0008] As a result, there is a problem that when the dust blowing by backwashing is performed while the fan is stopped, the backflow of dust flows out from the dust-laden air inlet of the dust collecting device, etc., so that the pollution has passed through the dust collecting device The pre-stage of dust collectors such as working spaces that realize air purification

Embodiment Construction

[0027] Hereinafter, the dust shaking method of the dust collector which concerns on preferred embodiment of this invention is demonstrated based on drawing. figure 1 It is a schematic diagram which shows the structure of the dust collector 1 which implemented the dust shaking method of the dust collector which concerns on the preferable embodiment of this invention.

[0028] Such as figure 1 As shown, the dust collector 1 includes a casing 2 . The inner space of the casing 2 is divided into a dust collection chamber 6 on the lower side and a clean room 8 on the upper side by the unit plate 4 . The peripheral edge of the unit plate 4 is airtightly connected to the inner wall surface of the case 2 .

[0029] The dust collecting chamber 6 , which is a space below the unit panel 4 , accommodates a plurality of cylindrical filters 10 and communicates with the external space through the air inlet 12 . On the other hand, clean room 8 , which is a space above cell plate 4 , commu...

Abstract

The invention provides a dust removing method of a dust collector to realize that dust does not flow backward to the front stage of the dust collecting device while maintaining a high dust removal efficiency. The dust removing method of the dust collecting device is used for removing dust from a filter in the dust collecting device. The dust collecting device (1) sucks a predetermined amount of dust collecting air generated by a fan (26) to circulate dust-containing air from one side of the filter (10) to the other side, thereby capturing and removing dust with the filter. The dust removing method of the dust collecting device includes the following steps: when a dust removing condition of the filter is established, reducing the dust collecting air volume of the fan to less than 50% of therated air volume; and while suctioning realized by the reduced dust collection air volume is performed, supplying pressurized air to the other side of the filter to remove dust adhering to the filterfrom one side of the filter.

Description

technical field [0001] The present invention relates to a dust removal method of a dust collector, and more specifically, to a dust removal method of dust from a filter of a dust collector equipped with a fan. Background technique [0002] There is known a dust collecting device that circulates dust-laden air containing dust from one side of a filter to the other side through suction by a fan or the like, and mainly catches and filters dust on one side of the filter. In such a dust collecting device, when the filter is clogged with dust and the filtering performance of the filter decreases after a predetermined operation time or the like, a dust removal operation is performed. [0003] Dust removal by so-called "backwashing" is known as this dust removal operation. In this backwashing, pressurized air such as a pulse jet (pulsejet) that flows in the direction opposite to the direction in which dust-laden air flows during dust collection is supplied to the other side of the ...
