ASPIRATION DEVICE Russian patent published in 2008 - IPC B01D45/12 

FIELD: mechanics.

SUBSTANCE: proposed aspiration device comprises grid-like cooler with cooling air feed branch pipe, dust separator communicating with purified air outlet pipeline and drawer. Novelty of the proposed invention consists in using vortex inertial dust separator with upper and lower inlet branch pipes communicating with the drawer intake branch pipe as the dust separator. Note here that the dust separator upper intake branch pipe communicates with the grid-like cooler air outlet branch pipe via a pipe furnished with first throttling valve and air feed pipeline communicates with branch pipe feeding cooled air into grid-like cooler, with dust separator lower inlet branch pipe via pipeline furnished with second throttling valve and with drawer suction branch pipe via pipeline furnished with third throttling valve.

EFFECT: high-efficiency purification of air coming out from grid-like cooler.
