Abstract

The utility model discloses an energy-saving boiler with multiple annular flues, comprising a furnace cover (1), a grate bar disc (2), a grate door (3), an ash door (4), a water inlet pipe (5), a water outlet pipe (6) and a smoke pipe (7); a middle water jacket (10) is arranged between a furnace body water jacket (8) and a hearth water jacket (9); the three water jackets are communicated with one another by an annular water jacket (11); the upper parts of the three water jackets are communicated with one another by a connecting pipe (12); the hearth water jacket (9) is provided with a smoke returning port (13); a smoke separating plate (14) is arranged between the hearth water jacket (9) and the middle water jacket (10); a smoke separating plate (15) is arranged between the middle water jacket (10) and the furnace body water jacket (8); the lower part of the middle water jacket (10) is provided with a smoke vent (16); and the rear part of the furnace body water jacket (8) is provided with a smoke outlet (17) which is communicated with the smoke pipe (7). The flue of the boiler is lengthened, and the heat energy is absorbed by the water in the water jacket, thus saving energy; and the smoke is discharged in a lower returning way so as to lead the dust to drop to the bottom part of the flue, thus reducing pollution.

Description

Multi-ringed flue power economized boiler

Technical field

The utility model relates to a kind of boiler.

Background technology

The flue of existing boiler is generally shorter, causes high temperature cigarette and a large amount of dust directly to drain in the atmosphere, not only causes the waste of heat energy, and severe contamination environment, this requires very not to be inconsistent with the energy-saving and emission-reduction of doing one's utmost at present to advocate.

Summary of the invention

The purpose of this utility model is to provide a kind of multi-ringed flue power economized boiler of energy-conserving and environment-protective.

Technical solution adopted in the utility model is, this multi-ringed flue power economized boiler, it comprises bell, stove rod plate, fire door, the ash door, water inlet pipe, outlet pipe, chimney, water jacket in the middle of establishing between furnace water jacket and the hearth water sleeve, three water jackets are connected by ring-shaped water jacket in the bottom of middle water jacket, be connected by tube connector on top, on hearth water sleeve, offer smoke-refeed mouth, between hearth water sleeve and middle water jacket, establish smoke baffle plate, between middle water jacket and furnace water jacket, establish smoke baffle plate, smoke hatch is established in bottom at middle water jacket, sets out mouth at the rear portion of furnace water jacket, and it is connected with chimney.

Owing to taked technique scheme, thus the utility model boiler not only flue extended, and flue is constructed round water jacket, like this, cigarette is in the circulation discharge process, and heat energy is wherein just fully absorbed by the water in the water jacket, reaches to improve the thermal efficiency, purpose of energy saving.Cigarette is lower returning type circulation discharging in addition, and the dust in the cigarette just sinks naturally in the flue bottom, thereby has reduced pollution, is beneficial to environmental protection.
