Accompanying drawing explanation
Fig. 1 is the profile of the coal powder burner for cement rotary kiln of band oxygen-enriched tiny-oil ignition;
Fig. 2 is the side view of Fig. 1;
In figure: housing 1, axial flow wind air channel 2, coal wind air channel 3, axial flow wind air compartment 4, swirl secondary air air channel 5, gaseous film control air channel 6, Secondary Air air channel 7, first baffle plate 8, First air air channel 9, second baffle 10, Tiny-oil ignition device 11, tiny-oil ignition oil gun 12, centre wind air channel 13, bluff body 14, tiny-oil ignition pulverized coal channel 15.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As illustrated in fig. 1 and 2, the coal powder burner for cement rotary kiln of band oxygen-enriched tiny-oil ignition device of the present invention is cylindric, its outer surface is housing 1, some coaxial pipes are fixed on the front portion of housing 1, the front portion of housing 1 is separated into centre wind air channel 13, swirl secondary air air channel 5, coal wind air channel 3, axial flow wind air channel 2 outward successively from interior, and bluff body 14 is fixed in the front end in centre wind air channel 13.There is in axial flow wind air channel 2 an axial flow wind air compartment 4.Tiny-oil ignition pulverized coal channel 15 inserts the central authorities in centre wind air channel 13, the part of centre wind air channel 13 beyond tiny-oil ignition pulverized coal channel 15 is gaseous film control air channel 6, the rear portion of housing 1 has Secondary Air air channel 7 and First air air channel 9, and Secondary Air air channel 7 communicates with axial flow wind air channel 2, swirl secondary air air channel 5 and air film cooling air channel 6 respectively.First air air channel 9 communicates with coal wind air channel 3 and tiny-oil ignition pulverized coal channel 15 respectively, and the first baffle plate 8 is fixed with coal wind air channel 3 place of communicating in First air air channel 9, First air air channel 9 second baffle 10 fixing with tiny-oil ignition pulverized coal channel 15 place of communicating.Tiny-oil ignition device 11 is fixed in tiny-oil ignition pulverized coal channel 15, and the oil gun mouth of the tiny-oil ignition oil gun 12 of Tiny-oil ignition device 11 is towards burner front end.
The course of work of the present invention is as follows: when opening stove, close the first baffle plate 8, open second baffle 10, ensure that burner presents oxygen enrichment state, promote that coal dust carries out oxygen-enriched combusting, thus quickening burning velocity, First air enters tiny-oil ignition pulverized coal channel 15 by First air air channel 9, ignites carry out fractional combustion in Tiny-oil ignition device 11 through tiny-oil ignition oil gun 12, thus improve burning condition, realize replace oil with coal, reduce the effect of oil consumption, greatly reduce cost simultaneously; Combustion flame enters cement kiln by bluff body 14, tiny-oil ignition pulverized coal channel 15 outer surface is around the gaseous film control wind 6 of one deck from Secondary Air air channel 5, thus prevent burner to be burned and wall slagging scorification, after burner enters normal operation, close second baffle 10, open the first baffle plate 8, First air enters coal wind air channel 3 through First air air channel 9, enter kiln combustion again, Secondary Air enters swirl secondary air air channel 5 through Secondary Air air channel 7, then enters in kiln the air capacity of supplementing needed for coal dust firing.
