Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, Figure 2 and with reference to Fig. 4 and Fig. 6, the smoke exhaust barrel of liquid collection function that what the utility model embodiment provided have, comprising: smoke exhaust barrel 1; Smoke exhaust barrel 1 is provided with expansion joint 11 and annular collector 10; Obviously, expansion joint 11 is the devices for regulating stroke when smoke exhaust barrel 1 occurs flexible, generally all arranges, for regulating the stroke of vertical direction perpendicular to the axis of smoke exhaust barrel 1.As Fig. 4 and Fig. 6, annular collector 10 is positioned at the top of expansion joint 11, annular collector 10 is in annular, and the inwall compact siro spinning technology of the outer ring of annular collector 10 and smoke exhaust barrel 1, the inner ring of annular collector 10 has upper overturning, and (that is, the inner ring edge of annular collector 10 is provided with circle stile upward; In Fig. 6, arrow is towards the direction towards namely air-flow blowout being exactly flanging); That is, when annular collector 10 is fixed on the inwall of smoke exhaust barrel 1, make the inwall of smoke exhaust barrel 1 form an opening up feeder, this feeder is used for the drop of above smoke exhaust barrel 1 inwall to collect.
Due to the relation by flue gas flow rate in smoke exhaust barrel, the drop of expansion joint more than 11 generally all slowly flows to expansion joint with the trend moved downward.The utility model owing to arranging annular collector 10 above expansion joint, thus enables the drop in smoke exhaust barrel above expansion joint 11 be enriched in annular collector 10, avoids drop and contacts with expansion joint and corrode the situation of expansion joint 11; Meanwhile, due to annular collector 10 flange upward, it also avoid air-flow in smoke exhaust barrel by liquid secondary entrainment may.In addition, it should be noted that, internal diameter due to expansion joint 11 internal diameter that is completely impossible and smoke exhaust barrel 1 is completely the same, at the pipeline section of internal diameter change, very easily because the change generation secondary entrainment of air-flow, and after arranging annular collector, air-flow upwards directly can not impact liquid film (drop of slowly flowing), also just avoid the generation of secondary entrainment.
As Fig. 2 and Fig. 3, on the basis of above-described embodiment, the bottom of smoke exhaust barrel 1 is provided with the elbow bend 2 for air inlet; Elbow bend 2 inwall is provided with elbow annular collector 15, and the structure of elbow annular collector 15 is identical with the structure of annular collector 10.Because air-flow is when flowing through bottom elbow, be subject to the barrier effect of elbow, the thin film drainage of elbow interior wall can unusual instability, the liquid film of smoke exhaust barrel 1 vertical direction can flow to elbow bend, and the liquid film of elbow bend 2 import department also can flow through elbow bend 2, and due to the action of turbulent flow of the air-flow in elbow, very easily there is secondary entrainment.The utility model examples of implementation, after being provided with elbow annular collector 15, can being collected the liquid film of elbow bend 2 both sides smoke exhaust barrel inwall, it also avoid the generation of secondary entrainment.Because elbow annular collector 15 is collected the liquid film of both sides; So preferably, the section of elbow annular collector 15 is T-shaped (as Fig. 7).The section of annular collector 10 adopts L shape (as Fig. 6).Elbow bend 2 generally adopts three joint elbow bends, can reduce manufacturing cost like this, and is better adhered in elbow by the drop in air-flow and collect.That is, elbow is more level and smooth, is more unfavorable for the collection of liquid in air-flow.
On the basis of above-described embodiment, smoke exhaust barrel 1 is also provided with first row water pipe 5, one end of first row water pipe 5 is connected with annular collector 10, and the other end is connected with elbow annular collector 15, with the fluid discharge of annular collector 10 being collected in elbow annular collector 15.As Fig. 2 and Fig. 3, annular collector 10, after collection liquid, is disposed in elbow annular collector 15, due to the effect of air-flow by first row water pipe 5, first row water pipe 5 is usually located at the interior curved of elbow bend 2, and first row water pipe is generally positioned at the lateral wall of smoke exhaust barrel 1.
Further, elbow bend 2 is also provided with second row water pipe 6 and discharge outlet 60; Discharge outlet 60 is opened in the lowest part (being arranged at the lowest part of elbow bend horizontal segment in other words) of elbow bend 2, and one end of second row water pipe 6 is connected with elbow annular collector 15, and the other end is connected with discharge outlet 60.As shown in Figure 1, obviously, the top of elbow annular collector 15 is connected with first row water pipe 5, and least significant end is connected with second row water pipe 6.Need in addition illustrate time, because elbow annular collector 15 is arranged on elbow bend 2 inwall, thus elbow annular collector 15 neither vertical row chimney axis, the also axis of out of plumb elbow bend 2 horizontal segment.
On the basis of above-described embodiment, more preferably, annular collector 10 has two, and annular collector 10 is separately positioned on above and below expansion joint 11, and the flanging of described annular collector 10 is towards the opposite.Be arranged at the annular collector 10 below expansion joint 11, its flanging, forms downward opening feeder down, upwards flows into expansion joint 11 to prevent liquid film.The setting of annular collector 10 further increases liquid collection effect, decreases the generation of secondary entrainment to greatest extent.
As illustrated in figures 1 and 8, for the ease of liquid collection, annular collector 10 is obliquely installed in smoke exhaust barrel 1, and in order to ensure flow velocity, annular collector 10 slanted angle is 5-10 degree; Namely be 5-10 degree with the angle R of horizontal plane.When annular collector 11 below expansion joint 11 is in tilted layout, its bottommost is connected with first row water pipe 5, only in this way the liquid that this annular collector 11 is collected could be entered in first row water pipe smoothly.
As Fig. 8, on the basis of above-described embodiment, further, expansion joint 11 is H apart from the distance of elbow bend 2, and the diameter of smoke exhaust barrel 1 is D, then H=1.5 ~ 2D.In ideal conditions, stand in the viewpoint of liquid collection, do not have expansion joint also will greatly reduce the secondary entrainment of liquid, be easy to by secondary entrainment return-air stream this is because liquid runs into the expansion joint that diameter differs.If but expansion joint is placed in practical application horizontal flue entrance top and is equivalent to smoke exhaust barrel diameter 1.5 to 2 times of positions.In this position, expansion joint 11 is roughly in the separation in gas-dynamic district, smoke exhaust barrel upper and lower, and two annular collector 10 that expansion joint 11 both sides are arranged all can effectively work, and this layout can minimize the chimney rain caused by expansion joint.
Above-described detailed description of the invention; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only detailed description of the invention of the present utility model; and be not used in restriction protection domain of the present utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
