Abstract
The utility model discloses a fin type vertical water pipe return stroke, and relates to a smoke return stroke baffle of a boiler and a heat exchange device inner container, which solves the problem that the return stroke of the existing structure is not conductive to improving the strength and the thermal efficiency of the boiler and is not conductive to scale removal and maintenance. The fin type vertical water pipe return stroke comprises a plurality of vertical water pipes, and fins of two vertical water pipes connected through two steel plates, wherein the upper parts of the vertical water pipes are provided with smoke outlets, the lower parts of the vertical water pipes are provided with small manifolds, one end of the fin is welded with the outer wall of the vertical water pipe, and the other end of the fin is mutually staggered and overlapped with the fin on the adjacent vertical water pipe. With the utility model, a heating surface of a furnace is increased, the size of the furnace is reduced, the flow path and the flow velocity of the smoke are increased so as to facilitate the circulation of smoke, water and other media, the media in the furnace fully absorb heat, energy is saved, environment is protected, the thermal efficiency is high, and the return stroke is not scaled easily and has long service life.
Description
Technical field
The utility model belongs to the technical field of boiler and other heat-exchange apparatus, relates to the flue gas backhaul baffle plate of a kind of boiler and heat-exchange apparatus inner bag, is specifically related to the backhaul of a kind of fin type vertical water pipe.
Background technology
The backhaul of the inner bag of boiler and heat-exchange apparatus all is that two of employings or polylith steel plate join in the prior art, the flue backhaul of water layer gap as boiler and heat exchanger left in the centre, the backhaul of this kind structure both had been unfavorable for that boiler fully absorbed heat, also carry the not intensity and the thermal efficiency of high boiler, more be unfavorable for snaking and maintenance.
Summary of the invention
The utility model is for the backhaul that solves existing structure is unfavorable for improving intensity, the thermal efficiency of boiler and is unfavorable for snaking and the problem of maintenance, and the backhaul of fin type vertical water pipe is provided.
The utility model is achieved through the following technical solutions:
The backhaul of fin type vertical water pipe, comprise some vertical water pipes, the fin that adjacent two vertical water pipes connect by two steel plates, vertical water pipe top is provided with exhanst gas outlet, the vertical water pipe bottom is provided with little collecting box pipe, one end of fin is welded on the outer wall of vertical water pipe, the overlap joint that intermeshes of the fin on the other end and the adjacent vertical water pipe.During use, the top of vertical water pipe backhaul is communicated with the upper water box of boiler, the bottom is communicated with little collecting box pipe, fin lap-joint does not weld, leave very little gap, this structure had both increased heating surface, reduce the volume of stove, increase the flow process and the flow velocity of flue gas again, also be convenient to water circulation in the stove, improve the intensity and the thermal efficiency of boiler backhaul, thereby make flue gas under the effect of fin type backhaul,, reach environmental protection and energy-conservation effect with the abundant heat exchange of boiler water layer, this fin type vertical water pipe backhaul can be provided with two or more in flue, is provided with according to the size of boiler and heat exchanger.
Described exhanst gas outlet also can be located at the bottom of vertical water pipe.
The utility model can be arranged in the boiler furnace flue and in other heat transmission equipment, medium can be water, oil, air, steam etc., is provided with two, three or more in flue.
Compared with prior art, the utlity model has following advantage:
(1) increases the heating surface of stove, reduce the volume of stove;
(2) flow process and the flow velocity of increase flue gas;
(3) intensity of increase flue backhaul reduces internal stress;
(4) be convenient to the circulation of media such as flue gas, water;
(5) the interior medium of body of heater is fully absorbed heat;
(6) energy-conserving and environment-protective, thermal efficiency height, less scaling, long service life.
