The utility model content
In order to overcome the adherent flow-disturbing poor effect of interior thorax helix that existing chimney is provided with; And the defective of difficult installation, the utility model aim to provide a kind of no rotten dust-collecting energy-saving chimney, and this chimney adopts flow-disturbing muscle structure; It gives disturbance when mobile to wet flue gas is adherent; Guarantee that wet flue gas is not adherent fully, exempt from its wet flue gas and contain of the corrosion of sour impurity, prolong the application life of chimney inner wall of stack.
To achieve these goals; The technical scheme that the utility model adopted is: said no rotten dust-collecting energy-saving chimney comprises that the bottom is provided with the into chimney barrel of mouth; Its design feature is; Also comprise many flow-disturbing muscle that are arranged on the chimney barrel inwall, the layout in the same way of said adjacent two flow-disturbing muscle, and the spacing between adjacent two two flow-disturbing muscle is 0.3m~6m.
Said flow-disturbing muscle is meant to be arranged on the chimney barrel inwall, and adherent wet flue gas is carried out flow-disturbing, reaches the fin of wet flue gas turbulent flow effect.
In order to guarantee the flow-disturbing effect, said every flow-disturbing muscle lift angle β with respect to the horizontal plane is preferably: 5 °≤β≤90 °, and 80 °<β≤90 ° more preferably.
Said every flow-disturbing muscle preferably by disjunct multistage and the fin of arranging in the same way form; Be that single flow-disturbing muscle is made up of disjunct multistage fin at the chimney barrel inwall from top to bottom; And these fins arrange in the same way, and this is for traditional several or tens interior thorax helixes, and the flow-disturbing muscle can reach hundreds of; Even more, so flow-disturbing better effects if.
See on the whole, said every flow-disturbing muscle be shaped as straight line, curve or broken line.
Further; According to actual needs; The cross sectional shape of crossing the chimney barrel axial line of said flow-disturbing muscle can be selected from least a in straight line, oblique line, curve and the broken line, and the flow-disturbing muscle can be higher than its other end near the end in chimney barrel axle center, also can be not less than its other end.
Further; In said adjacent two flow-disturbing muscle arbitrarily; On the cross sectional shape of crossing the chimney barrel axial line, top flow-disturbing muscle is not more than bottom flow-disturbing muscle near an end in axle center and the vertical distance Xb of chimney barrel wall near an end in axle center and the vertical distance Xa of chimney barrel wall to a flow-disturbing muscle on top with respect to a flow-disturbing muscle of bottom.
Said flow-disturbing muscle preferably is built into by fragment of brick, certainly, according to actual needs, also can adopt other material that can satisfy flow-disturbing muscle performance requirement, promptly corrosion-resistant, difficult aging, not labile material; Like various solid or hollow pots such as concrete block, metal derby, glass bloom, unit of plastic, new material piece, plate.
The upper side of above-mentioned flow-disturbing muscle can be wiped with mortar.Said flow-disturbing muscle can be through clamping, and the part material can adopt welding or bonding way to link to each other with chimney barrel.
By said structure, flue gas is pasting chimney barrel wall spiral and is rising through on the flow-disturbing muscle, because the flow-disturbing muscle can be divided into multistage, even reaches hundreds of sections, it can guarantee that to the disturbance better effects if of wet flue gas wet flue gas is not adherent fully,
Above-mentionedly advance mouth and be preferably one or two, its radial section shape can be rectangle, ellipse, polygon or circle.When a chimney is provided with two when advancing mouth, preferably advance the mouth layout that is parallel to each other, so that the flue dust that gets into can not have the purpose of rotten dust-collecting energy-saving with identical rotation direction in chimney barrel with these two; Also can form eddy flow, reach the purpose of no rotten dust-collecting energy-saving equally by a flue dust that advances the unidirectional entering of mouth.
Saidly advance mouth and be externally connected with the chimney flue, the arranged direction of the chimney barrel inwall flow-disturbing muscle that advances cigarette direction and adjacency of this chimney flue is in the same way; The oblique line flue that said chimney flue is the curve smoke channel that is positioned at the chimney barrel lower outside, be positioned at chimney barrel lower outside and the tangent line flue that is connected with this chimney barrel tangent line or be positioned at the chimney barrel lower outside and be connected with the non-tangent line of this chimney barrel.
Saidly advance mouth and be provided with and advance the chimney flue that mouth smoothly docks, this chimney flue can be that curve smoke channel, oblique line flue or tangent line flue mode are advanced mouth with chimney and be connected,
Preferred version as the utility model; In order to improve the circulation effect of flue gas stream further; A said side of advancing mouth is provided with the deflector that places in the chimney barrel, and the plane b that the end that this deflector is connected with chimney barrel and this deflector other end are constituted is 20 °~90 ° with respect to the angle of advancing mouth air deflector chimney barrel tangent line.Further, said deflector is straight plate, broken line plate or curve ruler.Arc more preferably, when deflector is arc, this arc deflector for the arc back of the body (convex surface) towards the chimney axis direction, be convenient to flue dust is carried out adherent water conservancy diversion.In order to make the circulation better effects if of flue gas stream, the said opposite side that advances mouth has a breach.
For the existing chimney that has two to advance mouth, also need guarantee two advance mouth the deflector layout that is parallel to each other, be convenient to flue gas and in chimney barrel, produce eddy flow with rotation direction.
Further, above-mentioned chimney barrel has different slope ratios from the bottom to top.
By said structure, the chimney of said structure is broken through traditional interior thorax helical design; Interior thorax helix improvement is the flow-disturbing muscle, simple in structure, easy to make; Adherent mobile wet flue gas disturbance better effects if, flue gas can get into chimney barrel through advancing mouth from curve smoke channel, tangent line flue or oblique line flue, can be before getting into chimney barrel; In curve smoke channel, tangent line flue or oblique line flue, produce good rotation in advance; Help to improve efficiency of dust collection, make that pitot loss is little, dust content greatly reduces, and plume rigidity is big; After flue gas got into chimney, under the effect of flow-disturbing muscle, flue gas continued to keep rising.Because flue gas stream rising centrifugal action, a small amount of dust granules that remains in the flue gas stream mainly is distributed in the flue center.Flue gas generation condensation is relevant with contained grit, at first is to rely on grit to form nucleus of condensation, enlarges gradually then and forms overall condensation.Because grit focuses mostly at the flue center, so condensation mostly occurs at flue axis one band, and nearly wall plume still can be kept the unsaturation state, and the wall drying is not corroded by condensed fluid.
Compare with existing chimney, the beneficial effect of the utility model is: the utility model adopts flow-disturbing muscle structure under the prerequisite that does not weaken dust collection effect; Flue gas circulation is smooth and easy, guarantees wet flue gas and contain sour impurity not adherent fully, greatly reduces wet flue gas and contains the corrosion of sour impurity to inner wall of stack; And structural stability is high; Environment protecting is good, and prolong application life greatly, and cost is cheap relatively
The utility model chimney and co-altitude, compare with the conventional chimney of discharge value, long service life, environment protecting improves 25-45%, and self resistance is low by 20%, thereby can reduce air-introduced machine power consumption about 8.5%; Flue gas under the disturbance of flow-disturbing muscle, is equivalent to cyclone dust collectors in tube, 30%-80% can gather dust.
Below in conjunction with accompanying drawing and embodiment the utility model is done further to set forth.
