Abstract
The utility model relates to a coal boiler without smoke and dust, which is a technical improvement of existing coal boilers without smoke and dust. The utility model is characterized in that a middle arch in a hearth of the boiler is vertically provided with a smoke screening wall which is build by a plurality of circular rings, and inner holes of the circular rings are circular holes, or conical holes, or inclined holes; the rear side of the middle arch can be also provided with a second middle arch, and the second middle arch is vertically provided with a smoke screening wall plate which is provided with a plurality of inclined holes to form a pair-arch double smoke screening wall structure, and therefore, carbon granules and cinders in smoke dust can be separated for many times and fall on a grate to be combusted again. The utility model has the advantages of simple structure, complete combustion, high thermal efficiency, long service life, etc.
Description
The utility model belongs to field of boilers.
Existing coal-fired smoke-removing boiler is the horizontal smoke board that porous is arranged that tilts in burner hearth, this boiler can improve coal-fired combustion efficiency, reduce the discharge capacity of flue dust, and improve the thermal efficiency of boiler, but exist smoke board tilt horizontal inconvenience, frangible, easy dust stratification, service life short, still have deficiency such as soot emissions.
The utility model purpose is to provide the coal-burning smoke-less dirt boiler of a kind of simple in structure, sufficient combustion, thermal efficiency height, long service life.
The purpose of this utility model is realized by following technical scheme: this coal-burning smoke-less dirt boiler is the technological improvement to existing coal-fired smoke-removing boiler, it comprises: furnace wall (14), drum (9) is settled in upper end at furnace wall (14), in drum (9), be provided with some smoke pipes (11), smoke pipe (11), outlet flue (7) is connected, on drum (9), be provided with water intaking valve (12), outlet valve (13), lower end in furnace wall (14) is provided with burner hearth (15), burner hearth (15) contacts with water screen tube (10), in burner hearth (15), be provided with face arch (1), hogging (16), rear arch (2), be provided with fire grate (8) in the below of burner hearth (15), secondary air channel (5) in that fire grate (8) below is provided with air inlet (6) and is communicated with burner hearth (15) is characterized in that: go up the perpendicular smoke shielding wall of being built by several annulus (18) (3) of putting in hogging (16).
The endoporus of said annulus (18) is a conical bore.
The endoporus of said annulus (18) is an angling hole.
Hogging (16) rear side in burner hearth (15) is provided with second hogging (17), goes up the perpendicular smoke shielding wall plate (4) with several angling holes (19) of putting in second hogging (17).
Coal-burning smoke-less dirt boiler of the present utility model is compared with existing coal-fired smoke-removing boiler because the perpendicular smoke shielding wall of building by several annulus of having put on the hogging of the utility model in burner hearth, it simple in structure, be convenient to esting, long service life; Smoke shielding wall can block the carbon granule in the flue dust, and ickings falls into fire grate and burns; The heat radiation of smoke shielding wall also can make the cold coal of just having gone in the burner hearth obtain preheating, destructive distillation, helps burning.Also owing to be provided with second hogging at the hogging rear side, the perpendicular smoke shielding wall plate of putting on second hogging with several angling holes, and with the smoke shielding wall on hogging, the hogging, composition is to encircleing two smoke shielding wall structures, repeatedly separated the falling on the fire grate of carbon granule in the flue dust, ickings burnt again, have sufficient combustion, no flue dust is discharged, the boiler thermal output advantages of higher.
The utility model is described in further detail to utilize embodiment shown in the drawings below.
Fig. 1 is a coal-burning smoke-less dirt boiler structure cross-sectional schematic.
Fig. 2 is an A-A cross-sectional schematic among Fig. 1.
Fig. 3 is the schematic diagram of annulus among Fig. 2 (18).
Fig. 4 is that the endoporus of annulus (18) is the conical bore schematic diagram.
Fig. 5 is that the endoporus of annulus (18) is the angling hole schematic diagram.
With reference to Fig. 1 and 2, drum of the present utility model (9) is communicated with water screen tube (10) welding, drum (9) is provided with water intaking valve (12), outlet valve (13), at the built-in some smoke pipes of drum (9) (11), the end of smoke pipe (11) is welded on the end socket of drum (9), and smoke pipe (11) is communicated with outlet flue (7).Furnace wall (14) is built composition by laying bricks or stones with refractory material.Furnace wall (14) contains drum (9), in the below of drum (9) is burner hearth (15), in burner hearth (15), build face arch (1) by laying bricks or stones with high heat conduction refractory material, hogging (16), second hogging (17), rear arch (2), be provided with fire grate (8) in the below of burner hearth (15), the secondary air channel (5) that is provided with air inlet (6) in the below of fire grate (8) and is communicated with burner hearth (15), go up the perpendicular smoke shielding wall (3) that esting is made up of several annulus (18) of putting in hogging (16), go up perpendicular put the smoke shielding wall plate (4) with several angling holes (19), annulus (18) in second hogging (17), smoke shielding wall plate (4) all uses high heat conduction refractory material pre-formed.Smoke shielding wall plate (4) also can adopt the annulus esting of several band angling holes to form.
With reference to Fig. 3-5, the endoporus of annulus (18) is a circular hole, or is conical bore, or is angling hole.
