Detailed description of the invention
It, below will be to embodiment in order to illustrate more clearly of inventive embodiments of the present invention or technical solution in the prior art Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments that the present invention invents, for those of ordinary skill in the art, in the premise not made the creative labor Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of structural schematic diagram of coal-gas burning dual-purpose boiler provided in an embodiment of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
Referring to Fig.1, a kind of coal-gas burning dual-purpose boiler is provided in the embodiment of the present invention, including cube structure Frame 100, the cross section of the frame 100 are rectangle, use fire resisting brick respectively on two opposite inner walls of the frame 100 At refractory wall 110 and refractory arch 120, the space between the refractory wall 110 and refractory arch 120 is the combustion chamber of boiler.
The mounting groove 111 for installing combustion gas device for igniting 200 is offered on the refractory wall 110, which is arc Shape slot, the tangent line for being located at described 110 outer wall one end of refractory wall are to tilt upward, and make to spray from the combustion gas device for igniting 200 Flame towards oblique upper enter the combustion chamber in.Described 200 one end of combustion gas device for igniting is located in the mounting groove 111, separately One end passes through the frame 100 and is connected to gas pipeline 210, which is connected to fuel gas transportation pipeline.Certainly, should Need to install the gas sources such as air gauge, pressure regulator valve control equipment on gas pipeline 210, these are the prior art, therefore the present invention Embodiment is not described in detail.
The frame 100 has opening on the side wall opposite with the side wall for being equipped with the combustion gas device for igniting 200, this is opened Fire grate is installed in mouthful, which includes fire grate segment 300 and live-roller 310.The quantity of the fire grate segment 300 be it is multiple, it is multiple The fire grate segment 300 connects form cricoid chain structure from beginning to end, all has multiple air holes on each fire grate segment 300, And also there is air hole between the two neighboring fire grate segment 300.The live-roller 310 includes driving roller and follower roller, two biographies Dynamic roller 310 is separately mounted to the both ends for the chain that the fire grate segment 300 forms, and the driven roller is located at outside the frame 100 Portion, driven voller are located at the lower portion.
The supporting block 320 for being used to support the chain, the support are installed inside the chain that the fire grate segment 300 forms Block 320 is hollow, offers on top surface and is connected with inside opening, is vertically fixedly mounted on the inner bottom surface of the supporting block 320 There are multiple wind deflectors 321, the height edge of the wind deflector 321 becomes larger on from the driven roller to the direction of driven voller.Institute State the inside of supporting block 320 and bottom blower 331 be connected with by ventilation duct 330, the ventilation duct 330 with inside supporting block 320 Junction be located at close to one end of the driven roller, the bottom blower 331 pumps external air by ventilation duct 330 To inside the supporting block 320, and in the internal flow of supporting block 320, during flowing, portion of air is directly up Flowing, the opening on 320 top surface of supporting block enter combustion chamber, another part air from the air hole of fire grate segment 300 It is flowed to one end close to driven voller, due to the blocking of the wind deflector 321, air changes direction and flows up, and eventually enters into Combustion chamber.Not only the fire coal on fire grate segment 300 can in this way come into full contact with air, and then improves combustion Efficiency is burnt, the flame that fired coal combustion generates also is blowed into combustion chamber, heat is made to be gathered effective use.
There is inclined ash receiving plate 340, the ash receiving plate 340 below the fire grate that the fire grate segment 300 and live-roller 310 form One end is fixed on the frame 100 and is equipped on the inner sidewall of the combustion gas device for igniting 200, and the other end passes through opposite side wall simultaneously It extend out to outside the frame 100, and exposes to one end height outside frame 100 height for being lower than the other end.The ash Plate 340 is equipped with dismountable ash slot 350 in the one end being located at outside frame 100, and the coal ash fallen from the fire grate exists Ash receiving plate 340 described in gravity lower edge slides into the ash slot 350, it is only necessary to periodically take out the ash slot 350 Outwell coal ash therein.The preferred detachable mounting means of ash slot 350 is to be slidably installed in the embodiment of the present invention, ash Slot 350 can slide back and forth in the horizontal direction.
The fire grate is fixedly installed with coal scuttle 360 on the top surface being located at outside the frame 100, and the coal scuttle 360 is Up big and down small funnel-shaped structure is equipped with revolving valve 361 in the interior bottom of coal scuttle 360, which rotates the coal Fire coal in bucket 360 is at the uniform velocity laid on the fire grate segment 300, and fire coal burns as fire grate segment 300 enters combustion chamber, The coal ash to have burnt is fallen on the ash receiving plate 340.
There is gap, and the coal scuttle 360 is towards 100 side of frame between the coal scuttle 360 and the lateral wall of frame 100 Side wall extend into inside the frame 100, between the side wall of the part and the frame 100 protruded into formed ventilation opening 370.Institute State on frame 100 the surface of the ventilation opening 370 be equipped with top blower 371, the top blower 371 by outside air It pumps in the ventilation opening 370, air passes through the ventilation opening 370 and enters in combustion chamber.Since the ventilation opening 370 abuts The outlet of the coal scuttle 360, therefore the air blown out from the ventilation hole 370 dispels the fire coal being discharged from coal scuttle 360, Avoid coal-fired agglomerating reduction efficiency of combustion.
The flame generated when coal-fired burning in a combustion chamber stops to make in the guiding of the refractory wall 110 and refractory arch 120 It is gathered in the center of combustion chamber under, the utilization rate of energy can be improved.
Exhaust pipe 400 is installed on the side wall at the close top of the frame 100, the exhaust pipe 400 at polyline shaped, and It is connected to inside the frame 100.The exhaust pipe 400 is equipped with ash bucket 410 in the bottom of bending place, the ash bucket 410 Be detachably arranged on the exhaust pipe 400, and be connected to inside the exhaust pipe 410.The exhaust gas generated when fired coal combustion Middle to have particulate matter, particulate matter, which enters after the exhaust pipe 400, collides 400 inner wall of exhaust pipe, therefore particulate matter in bending place Speed can be greatly lowered, finally slide along exhaust pipe 400 into the ash bucket 410.It only needs periodically to tear ash bucket 410 open Under outwell dust stratification therein.
Disclosed above is only several specific embodiments of the invention, and still, the embodiment of the present invention is not limited to this, is appointed What what those skilled in the art can think variation should all fall into protection scope of the present invention.
