Problems solved by technology

[0002] In the traditional cyclone dust collector, the airflow carrying dust enters the volute along the tangential direction. During the rotation process, the dust loses speed after being hit by the centrifugal force on the inner wall of the casing, and falls into the dust collecting hopper by gravity, and the airflow passes through The inner cylinder moves from bottom to top to realize the separation of dust and gas. However, since there is no obvious interface between the air flow and the settled dust particles, the dust will be re-wrapped by the air flow, thereby reducing the dust collection efficiency.
Especially for large-scale dust collectors, the distance between the dust particles near the center and the inner wall of the housing is large during the rotation process, and they cannot reach the inner wall of the housing, so the dust and gas cannot be separated; the air flow changes from downward to upward after the rotation is completed. Movement will cause greater resistance loss, so energy consumption is higher

Embodiment 1

[0020] Embodiment 1, single-channel mode see figure 2 , the dust-laden air enters from the air inlet 1, and moves in the direction of the Archimedes spiral in the spiral channel 4, and the dust moves outwards through the dust hole 10 of the porous isolation plate 3 under the action of centrifugal force, and enters the gas-solid isolation area 5, The dust particles lose speed after hitting the inner wall of the separation body 2, and fall into the ash collecting hopper 6 by gravity. After reaching the central area, the purified air moves upwards and enters the air outlet 7 to realize efficient separation of dust and gas.

Embodiment 2

[0021] Embodiment 2 two-channel mode see image 3 After the dust-laden airflow enters from the air inlet 1, the inlet air distribution plate 8 divides the airflow into two parts, one part enters the outer ring spiral channel 4, and the other part enters the inner ring spiral channel 4. The airflow in the inner and outer ring spiral channel 4 moves in the direction of the Archimedes spiral, and the dust moves outwards through the dust hole 10 of the porous isolation plate 3 under the action of centrifugal force, and enters the gas-solid isolation area 5, and the dust particles hit the separation body 2 After the inner wall loses speed, it falls into the ash collecting hopper 6 by gravity, and the purified two-channel airflow reaches the central area and moves upward, part of which is mixed, and part of which enters the air outlet 7 to achieve efficient separation of dust and gas.

Abstract

The invention relates to dust removal equipment, in particular to a dust collector with spiral channels. The dust collector with the spiral channels comprises an air inlet, a separating main body, a dust collection hopper and an air outlet, wherein the middle part of the dust collector is provided with the separating main body; the upper part of the dust collector is provided with the air outlet; the lower part of the dust collector is provided with the dust collection hopper; the spiral channels are formed in the separating main body; and porous isolation plates are fixedly connected in each spiral channel through partition plates. The spiral flow can ensure that the dust collection route is relatively long, and the action of centrifugal force is relatively large; airflow channels are not formed in a gas-solid isolation area, and gas is still, so that secondary and multiple mixing of dust particles and airflow can be avoided; a multi-channel mode ensures that the distance that the dust particles reach the gas-solid isolation area is shortened, so that the dust collection efficiency is improved; the spiral flow horizontally moves to a central area, and then moves upwards to the air outlet, and the movement route of the airflow is simpler, so that the resistance loss is reduced; and the height of the dust collector is small, so the processing set-up is relatively simple when the dust collector is applied.
