Abstract

The utility model discloses a boiler with smoke returning pipes. In the boiler with the smoke returning pipes, a cylindrical water jacket is vertically arranged at a hearth opening; the upper part of the cylindrical water jacket is communicated with an annular water jacket of a top layer; the side surface of the cylindrical water jacket and a hearth water jacket form an ascending flue; the ascending flue is communicated with an annular cavity which is sunken at the upper part of the hearth water jacket; the bottom of the hearth water jacket is connected with and provided with an annular flue; a plurality of smoke returning pipes are vertically arranged in the hearth water jacket; the upper openings of the smoke returning pipes are arranged on a bottom panel of the annular cavity; the lower openings of the smoke returning pipes are arranged on a top panel of the annular flue; and the annular flue is connected with a chimney through a smoke outlet passage. The high-temperature smoke dust in a hearth of the boiler with the smoke returning pipes is returned into the annular flue through the smoke returning pipes arranged in the hearth water jacket and then is discharged by the chimney. Thus, the residual heat of the high-temperature smoke dust can be adequately absorbed by the water packaging the smoke returning pipes in a downward returning process, and thus an energy-saving effect is achieved; and the smoke dust naturally falls into the annular flue in a falling process and is not discharged into the air, and thus an environmental protection effect is obtained.

Description

Return flue tube boiler

Technical field

The utility model relates to a kind of boiler.

Background technology

At present, most of boilers all are directly emitted high-temperature smoke by chimney, and its drawback is: the one, be rich in a large amount of heat energy in the high-temperature smoke, and emit in vain, caused the serious waste of the energy; The 2nd, volume of smoke drains in the atmosphere, can cause serious air pollution, is unfavorable for that the environmental protection and the people's is healthy.

Summary of the invention

The purpose of this utility model is to provide a kind of flue tube boiler that returns of energy-conserving and environment-protective.

Technical solution adopted in the utility model is: this flue tube boiler that returns, comprise fire door, water inlet pipe, outlet pipe, stove rod plate, chimney, shoot door one, bell, vertically establish a cylindrical water jacket at stockhole, it is gone up and is communicated with the ring-shaped water jacket of top layer, side and hearth water sleeve constitute uptake flue, uptake flue is communicated with the toroidal cavity that hearth water sleeve top falls in, connect in the bottom of hearth water sleeve and to establish annular flue, several smoke pipes that return vertically are set in hearth water sleeve, on the bottom panel that is opened in toroidal cavity suitable for reading that returns smoke pipe, end opening is opened on the top panel of annular flue, and annular flue is connected with chimney by smoke outlet flue.

Owing to taked technique scheme,, emitted by chimney again so the high-temperature smoke in the utility model burner hearth is to return in the annular flue by the several smoke pipes that return that are arranged in the hearth water sleeve.High-temperature smoke is in the process of returning down like this, and the water absorption that its waste heat just can be wrapped fully and return smoke pipe reaches energy-saving effect; Its flue dust just sinks in annular flue naturally in the decline process, and unlikely draining in the atmosphere played environmental-protection function.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the utility model side perspective schematic diagram;

Fig. 2 is the utility model side-looking cut-away view.

The specific embodiment

Embodiment 1, as depicted in figs. 1 and 2, this flue tube boiler that returns, comprise fire door 1, water inlet pipe 2, outlet pipe 3, stove rod plate 4, chimney 5, shoot door 1, bell 7, vertically establish a cylindrical water jacket 8 at stockhole, it is gone up and is communicated with the ring-shaped water jacket 9 of top layer, side and hearth water sleeve 10 constitute uptake flue 11, uptake flue 11 is communicated with the toroidal cavity 12 that hearth water sleeve 10 tops fall in, connect in the bottom of hearth water sleeve 10 and to establish annular flue 13, several smoke pipes 14 that return vertically are set in hearth water sleeve 10, returning suitable for reading 15 of smoke pipe 14 is opened on the bottom panel of toroidal cavity 12, end opening 16 is opened on the top panel of annular flue 13, and annular flue 13 is connected with chimney by smoke outlet flue 17.

Embodiment 2, and as the embodiment 1 described flue tube boiler that returns, hearth water sleeve 10 is communicated with chimney water jacket 19 by box water jacket 18, and shoot door 2 20 is established in chimney water jacket 19 bottoms.

Embodiment 3, as embodiment 1 or the 2 described flue tube boilers that return, offer shoot door 3 21 in the position of the corresponding annular flue 13 of body of heater.
