the current intelligence of current in channel circulation structure of the present invention is as follows: cold water enters the first left water circulation zone 1.1 of left cover 1 from water inlet 1a under pressure, enter in the first heat radiation straight pipe 4.1 after filtering by filter screen 5, enter in the first right water circulation zone 3.1 on right cover plate 3 via the first heat radiation straight pipe 4.1, flow to again the second left water circulation zone 1.2 of left cover 1 left via the second heat radiation straight pipe 4.2, flow to again the second right water circulation zone 3.2 of right cover plate 3 to the right via the 3rd heat radiation straight pipe 4.3, flow to the 3rd left water circulation zone 1.3 of left cover 1 left via the hot straight pipe 4.4 that scatters again, flow to again the 3rd right water circulation zone 3.3 of right cover plate 3 to the right via the 5th heat radiation straight pipe 4.5, flow to again the 4th left water circulation zone 1.4 of left cover 1 left via the 6th heat radiation straight pipe 4.6, flow to again the 4th right water circulation zone 3.4 of right cover plate 3 to the right via the 7th heat radiation straight pipe 4.7, flow to again the 5th left water circulation zone 1.5 of left cover 1 left via the 8th heat radiation straight pipe 4.8, flow to again the 5th right water circulation zone 3.5 of right cover plate 3 to the right via the 9th heat radiation straight pipe 4.9, flow to again the 6th left water circulation zone 1.6 of left cover 1 left via the tenth heat radiation straight pipe 4.10, flow to again the 6th right water circulation zone 3.6 of right cover plate 3 to the right via the 11 heat radiation straight pipe 4.11, flow to again the 7th left water circulation zone 1.7 of left cover 1 left via the 12 heat radiation straight pipe 4.12, flow to again the 7th right water circulation zone 3.7 of right cover plate 3 to the right via the 13 heat radiation straight pipe 4.13, flow to the 8th left water circulation zone 1.8 of left cover 1 left via the tenth hot straight pipe 4.14 that scatters again, flow to again the 8th right water circulation zone 3.8 of right cover plate 3 to the right via the 15 heat radiation straight pipe 4.15, flow to again the 9th left water circulation zone 1.9 of left cover 1 left via the 16 heat radiation straight pipe 4.16, flow to again two the 9th right water circulation zones 3.9 of right cover plate 3 to the right via two group of the 17 heat radiation straight pipe group 4.17, flow to again two the tenth left water circulation zones 1.10 of left cover 1 left via two group of the 18 heat radiation straight pipe group 4.18, flow to again two the tenth right water circulation zones 3.10 of right cover plate 3 to the right via two group of the 19 heat radiation straight pipe group 4.19, flow to again two the 11 left water circulation zones 1.11 of left cover 1 left via two group of the 20 heat radiation straight pipe group 4.20, flow to again two the 11 right water circulation zones 3.11 of right cover plate 3 to the right via two group of the 21 heat radiation straight pipe group 4.21, flow to again the 12 left water circulation zone 1.12 of left cover 1 left via two group of the 22 heat radiation straight pipe group 4.22, flow out from delivery port 1b at last, thereby waterway circulating and exchange heat have been completed.
The present invention is divided into water circulation zone not of uniform size with the chamber of left cover 1 and right cover plate 3, and adopt asymmetric staggered floor heat radiation straight pipe to design, the heat radiation straight pipe has two kinds of specifications of thickness, make the current area in each water circulation zone identical, thereby guarantee that water velocity is identical in the situation that pressure is identical, therefore, the current sealing area that Large Diameter Pipeline is corresponding is little, and water circulation corresponding to pipe with small pipe diameter zone is large.
Because the right water circulation zone on the left water circulation on left cover 1 zone and right cover plate 3 is not corresponding, current flow path along W shape in channel circulation structure of the present invention flows, compare with in the past straight flow path, flow path of the present invention is longer, thereby guaranteed to realize maximum heat exchange area in minimum space, extend the current of heat radiation straight pipe and the heat-exchange time of high-temperature fuel gas, made heat exchange more abundant, greatly improved heat exchange efficiency.The heat radiation straight pipe has two kinds of specifications of thickness, and according to from coarse to fine, be listed as to solid matter by dredging, thereby brought following advantage: can guarantee that the circulation of air in the combustion chamber is without hindrance on the one hand, combustion gas is fully burned, reduce the useless smoke waste gas discharging that produces when insufficient due to burning, improved the utilization rate of combustion gas, reduced resource consumption, and be difficult for carbon distribution in the combustion chamber, guarantee high efficient heat exchanging; When flowing in channel circulation structure as the water of heat transfer medium on the other hand, can absorb layer by layer the heat subregion, guarantee that the heat that fuel gas buring discharges is fully absorbed by the water in the straight pipe that dispels the heat, and has reduced thermal loss.
The present invention is simple in structure, and thermal conversion efficiency is high, security performance is good, reliability is strong, makes get up also very facility of operation and maintenance.
