Abstract
The utility model discloses a four return-stroke horizontal boiler, comprising a boiler shell and a furnace in the boiler shell, wherein a water cavity is formed between the boiler shell and the furnace, the inner cavity of the furnace is a bypass type flue and the bypass type flue comprises four return-stroke segments. The heating area of the boiler is increased, the fume exhaust temperature of the boiler is reduced and the heat efficiency of the boiler is increased.
Description
Technical field
The utility model relates to the heat resource equipment technical field, especially relates to a kind of four-return stroke horizontal boiler.
Background technology
Along with rising steadily and the continuous enhancing of environmental consciousness of energy prices, boiler commonly used in producing, living, need continuous technological innovation could satisfy the needs in market, the technical staff constantly produces the various boiler of formal construction around the theme of energy-conserving and environment-protective, but does not see the horizontal boiler of the many backhauls of flue on the market as yet.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of four-return stroke horizontal boiler, increases the heating surface area of boiler, reduces the exhaust gas temperature of boiler smoke, improves the thermal efficiency of boiler.
For achieving the above object, the utility model is by the following technical solutions: four-return stroke horizontal boiler of the present utility model comprises shell and is arranged at flue in the shell, form water cavity between shell and the flue, described flue inner chamber is the winding type flue, and described winding type flue comprises four backhaul sections.
Further, be provided with horizontal water pipe in each backhaul section of described winding type flue, laterally water pipe pass through described winding type flue and with described water cavity UNICOM.
The beneficial effects of the utility model are: because boiler of the present utility model has increased the stroke of flue gas, strengthened the area that boiler is heated, make not clean-burning as yet propellant composition free further fully burning before discharging boiler of carrying in the flue gas, not only reduced the pollution of smoke evacuation, and reduced the temperature of discharging fume, improved the thermal efficiency of boiler.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following specification and the accompanying drawing.
Description of drawings
Fig. 1 is a boiler furnace flue structural representation of the present utility model.
Fig. 2 is the vertical view of boiler furnace flue shown in Figure 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a boiler furnace flue structural representation of the present utility model, because main inventive point of the present utility model is flue, the shell of boiler is no longer shown in the figure, those skilled in the art are by reading literal and can understanding the utility model in conjunction with the accompanying drawings, in conjunction with Fig. 1, shown in Figure 2, four-return stroke horizontal boiler of the present utility model comprises shell and is arranged at the interior flue 1 of shell, form water cavity between the outer wall of shell and flue 1, described flue inner chamber 2 is the winding type flue, described winding type flue comprises four backhaul sections, be respectively the A-B section, B-C section, C-D section and D-E section.Each backhaul section at described winding type flue is provided with some horizontal water pipes 3, in the present embodiment, in the B-C section, the flue of C-D section and D-E section is provided with horizontal water pipe respectively, described horizontal water pipe all pass through described winding type flue and with described water cavity UNICOM.During use, flue gas enters the inner chamber 2 of flue 1 from inlet A, then successively by the A-B section, and the B-C section, the flue of C-D section and each backhaul section of D-E section arrive at last and exports behind the E place again by impact tube discharge boiler body.Because boiler of the present utility model has increased the stroke of flue gas, strengthened the area that boiler is heated, make not clean-burning as yet propellant composition free further fully burning before discharging boiler of carrying in the flue gas, not only reduced the pollution of smoke evacuation, and reduced the temperature of discharging fume, improved the thermal efficiency of boiler.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
Claims (2)
1. a four-return stroke horizontal boiler comprises shell and is arranged at the interior flue of shell, and form water cavity between shell and the flue, it is characterized in that: described flue inner chamber is the winding type flue, and described winding type flue comprises four backhaul sections.
