For solving the problems of the technologies described above, the utility model adopts following technical scheme: the dust removal integrated boiler of coal gas desulfurization comprises: boiler body; Said boiler body is provided with burner hearth, heat exchange hydroecium and is enclosed in the water jacket of said burner hearth; Said water jacket is connected with said heat exchange hydroecium, is provided with the heat exchange fire grate that is communicated with said heat exchange hydroecium and water jacket in the said burner hearth, and heat exchange fire grate and following heat exchange fire grate are drawn together in said recuperative furnace package; The zone that is positioned at said heat exchange fire grate down below is a lower combustion chamber; Zone on said between heat exchange fire grate and the following heat exchange fire grate is a upper combustion chamber, and being positioned at said zone of going up heat exchange fire grate top is coal storeroom, and said coal storeroom is provided with coal feeding hole; Said coal storeroom communicates with the chimney of said boiler; Be provided with the boiler fire tube in the said heat exchange hydroecium, the burner that advances of said boiler fire tube communicates with said lower combustion chamber, and the crater of said boiler fire tube directly is connected with water dust scrubber.
Preferably, the coal feeding hole of said coal storeroom is away from said heat exchange fire grate.
Preferably; Said boiler also comprises an air blast; Said air blast is connected with blast pipe through a connection pipeline; Said blast pipe comprises blast pipe and following blast pipe, and the said blast pipe of going up is arranged at said top of going up the heat exchange fire grate, and said blast pipe down is arranged between heat exchange fire grate and the following heat exchange fire grate.
Preferably, said chimney is connected on the said connection pipeline, is hinged with an air register that is used to regulate wind direction in said chimney and connection place that is connected pipeline.
After having adopted technique scheme, the beneficial effect of the utility model is: because the crater of said boiler fire tube directly is connected with water dust scrubber, so this boiler structure is compact, is beneficial to Installation and Debugging and saves installing space.
Because the coal feeding hole of said coal storeroom is away from said heat exchange fire grate,, thereby reduced boiler attendance worker's working strength so the volume that burner hearth can be done is bigger.
Because said boiler also comprises an air blast; Said air blast is connected with blast pipe through a connection pipeline; Said blast pipe comprises blast pipe and following blast pipe; The said blast pipe of going up is arranged at said top of going up the heat exchange fire grate, and said blast pipe down is arranged between heat exchange fire grate and the following heat exchange fire grate, thereby has improved the thermal efficiency of this boiler.
Because said chimney is connected on the said connection pipeline, is hinged with an air register that is used to regulate wind direction in said chimney and connection place that is connected pipeline, thereby has replaced magnetic valve, has reduced manufacturing cost.

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the front section view of the utility model embodiment;
Fig. 3 is the cutaway view at A-A place among Fig. 1;
Wherein, 1 boiler body, 2 burner hearths, 3 heat exchange hydroeciums, 4 water jackets, heat exchange fire grate on 5; 6 times heat exchange fire grates, 7 lower combustion chamber, 8 upper combustion chamber, 9 coal storeroom, 10 coal feeding holes; 11 chimneys, 12 boiler fire tubes, 13 advance burner, 14 craters, 15 water dust scrubbers; 16 air blasts, 17 connect pipelines, blast pipe on 18,19 times blast pipes, 20 air registers.
The specific embodiment
As Fig. 1,2 and 3 common shown in, the dust removal integrated boiler of coal gas desulfurization comprises: boiler body 1; Said boiler body 1 is provided with burner hearth 2, heat exchange hydroecium 3 and is enclosed in the water jacket 4 of said burner hearth, and said water jacket 4 is connected with said heat exchange hydroecium 3, is provided with the heat exchange fire grate that is communicated with said heat exchange hydroecium 3 and water jacket 4 in the said burner hearth 2; Heat exchange fire grate 5 and following heat exchange fire grate 6 are drawn together in said recuperative furnace package, and the zone that is positioned at said time heat exchange fire grate 6 belows is a lower combustion chamber 7, and the zone on said between heat exchange fire grate 5 and the following heat exchange fire grate 6 is a upper combustion chamber 8; Being positioned at said zone of going up heat exchange fire grate 5 tops is coal storeroom 9; Said coal storeroom 9 is provided with coal feeding hole 10, and said coal storeroom 9 communicates with the chimney 11 of said boiler, is provided with boiler fire tube 12 in the said heat exchange hydroecium 3; The burner 13 that advances of said boiler fire tube 12 communicates with said lower combustion chamber 7; The crater 14 of said boiler fire tube 12 directly is connected with water dust scrubber 15, and the coal feeding hole 10 of said coal storeroom 9 is away from said heat exchange fire grate, and said boiler also comprises an air blast 16; Said air blast 16 is connected with blast pipe through a connection pipeline 17; Said blast pipe comprises blast pipe 18 and following blast pipe 19, and the said blast pipe 18 of going up is arranged at said top of going up heat exchange fire grate 5, and said blast pipe 19 down is arranged between heat exchange fire grate 5 and the following heat exchange fire grate 6; Said chimney 11 is connected on the said connection pipeline 17, is hinged with an air register 20 that is used to regulate wind direction in said chimney 11 and connection place that is connected pipeline 17.
