Ultra-centrifugal dust remover adopting spraying device

Abstract

The invention relates to the technical field of dust removing equipment and discloses an ultra-centrifugal dust remover adopting a spraying device. The ultra-centrifugal dust remover comprises a rack,a box body, a spraying device and a motor, wherein the box body and the motor are mounted on the rack; the box body comprises a gas inlet, a gas outlet and a downspout funnel; the gas inlet is formedin the top of the box body; the spraying device is mounted on the gas inlet; the gas outlet is formed in a side face of the box body; the downspout funnel is located below the box body; the box bodyis internally provided with a rotary shaft and a rotor; two ends of the rotary shaft are fixed at two sides of the rack respectively; the rotor sleeves the rotary shaft; the rotor is provided with a first filtering screen, a second filtering screen and a plurality of blades; the motor is connected with one end of the rotary shaft through a transmission device. According to the ultra-centrifugal dust remover disclosed by the invention, the spraying device is mounted at the gas inlet of the centrifugal dust removing equipment and water mist adsorbs dust so that a plurality of dust with small grain diameters becomes dust with relatively large grain diameters and the dust removing efficiency is improved; meanwhile, an inclined plane structure is arranged at the bottom of the box body so that water with the dust is convenient to collect by the downspout funnel.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to an ultracentrifugal dust collector. Background technique [0002] Centrifugal dust collector is one of the most widely used dust removal equipment in the industry. It is mostly used as equipment for smoke and dust removal, multi-stage dust removal and pre-dust removal for small coal-fired boilers. Its dust removal principle is similar to that of the reverse inertial force dust removal device. However, the dust-laden airflow in the inertial force dust collector is only affected by the shape of the equipment or the baffle, simply changing the direction of the streamline, and only makes half a circle or one circle; the airflow in the centrifugal force dust collector can rotate more than one circle, The swirling flow velocity is also greater, so the particles in the swirling air flow are subjected to a much stronger centrifugal force than gravity. For small-diameter,...

Problems solved by technology

[0003] However, most of the centrifugal dust collectors currently on the market are not equipped with spray devices, and only rely on the centrifugal force generated by the rotating air flow to separate the dust, while some dust with extremely small particle sizes need to increase the flow rate of the rotating air flow to remove them. Large requirements are high, and it is difficult for ordinary equipment to remove dust with extremely small particle sizes
