Abstract
The utility model relates to a symmetric volute chimney inlet device which is characterized in that: the wind enters as a symmetric double flues tangent way and forms a pair of force couples which mutually impel to form a high speed rotating vortex so as to make the chimney elevate the raising height of the smoke; the wind inlet of the volute reduces resistance and benefits the landing of the thick soot; and the rotating airflow beneficial for the soot to rub the water film in a big area and to elevate the efficiency of dust removing.
Description
This reality has novel genus industrial fumes draining technology field, and the dual formula spiral case chimney that particularly a kind of chimney advances mouth advances the cigarette device.
At present, chimney advance mouth all be two flues or single flue all with central straight to advancing chimney, the normal air intake, chimney bottom is established the plate washer that is higher than 1.5 times of flue heights, plate washer is arranged with degree at 45 angle, flue center.Big, the non-tangent line air intake of this arrangement form resistance can not form swirling eddy, cigarette speed is slow, influences the rising height of flue gas, and shortcoming is more.
The utility model is for overcoming above-mentioned shortcoming, advance to change tangent line antithesis air intake when cigarette device two flues advance a chimney into and design a kind of dual formula spiral case, plate washer is set in the middle of removing from, the chimney hypomere establishes that eddy flow spiral case, two flue air intakes form a pair of couple, spiral case air intake resistance is little, two air-flows form swirling eddy, promote mutually, improved the rising height of flue gas greatly.
The technical solution of the utility model is that the spiral case 1 of chimney hypomere connects Venturi tube 2, and Venturi tube 2 connects flue 3, and chimney 4 connection spiral cases 1, two flue 3 tangent line in opposite directions advances cigarette, forms a pair of couple promotion air-flow (plume) rotation and rises.
The technical solution of the utility model is compared with routine techniques, has simple in structurely, and tangent line air intake (cigarette) resistance is little, and air-flow becomes streamlined rotation to rise, and the relative tangent line air intakes of two flues (cigarette) form a pair of couple and further promote the air-flow rotation.The rebuffed landing of favourable dust under the effect of swirling eddy, the absorption of favourable water film dedusting is gathered dust, and compares with conventional chimney, and atmosphere hoist height increases 1.5-2 doubly.
Accompanying drawing of the present utility model is the cutaway view of embodiment of the present utility model, and the utility model will be further described below in conjunction with accompanying drawing.
