Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: 1, heat-accumulating burner shell; 2, heat storage; 3, connecting rod; 4, cone member; 5, baffle brick; 6, burner block; 7, air intake pipeline; 8, multiple gas entry pipeline.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described below.
As shown in Figure 1, a kind of multi-functional burner, comprise burner metal shell 1, air intake pipeline 7, multiple gas entry pipeline 8, heat storage 2, connecting rod 3, cone member 4, baffle brick 5 and burner block 6, heat storage 2 is arranged in burner metal shell 1, described heat storage 2 is sandwich construction, multilayer heat storage 2 arranges from left to right, and heat storage 2 center is provided with connecting rod, and connecting rod 3 front end is provided with cone member 4.Described heat storage 2 is 6 Rotating fields, and every one deck is all provided with accumulation of heat hole, and accumulation of heat hole increases gradually from left to right, and accumulation of heat bore dia in the rightmost side is direct 4 times of accumulation of heat hole, left side.Adopt multilayer heat storage to arrange, improve the absorbability of heat storage 2 pairs of flue gas heat, decrease the waste of heat, described connecting rod 3 is provided with sealing device with cone member 4 junction; Described connecting rod 3 lower end is provided with fixing sliding rail.Connecting rod 3 is connected with cone member 4, being provided with sealing device prevents gas from entering, reduce the corrosion of high-temperature gas to connecting rod 3 and cone member 4 inside, coal gas of high temperature and air is avoided to mix in advance, described connecting rod 3 is connected with fixing sliding rail relative motion, make connecting rod action on trapped orbit, can not be subjected to displacement, ensure that the reliability of cone member 4 action, cone member 4 directly contacts with fire door, often by high-temperature baking, described cone member is made up of refractory material, can extend the service life of cone member 4.
Its operation principle is: heat storage 2 is sandwich construction, multilayer heat storage 2 arranges from left to right, heat storage is 6 Rotating fields, and every one deck is all provided with accumulation of heat hole, and accumulation of heat hole increases gradually from left to right, accumulation of heat bore dia in the rightmost side is 4 times of leftmost side accumulation of heat bore dia, when heat-accumulating burner burns, coal gas and air are flowed into from left to right by gas inlet pipeline 8 and air inlet duct 7, after heat storage 2 accumulation of heat, temperature reaches about 1200 DEG C, takes fire; When heat-accumulating burner is in heat storage state, high-temperature flue gas enters burner by combustion-supporting air outlet, and right-to-left enters burner, and heat storage is discharged by air intake pipeline 7 after absorbing fume afterheat, discharges flue-gas temperature and is down to 100 DEG C.Burner is alternately in burning and accumulation of heat two states.
When driving connecting rod 3 to drive cone member 4 to move backward along burner block 6 centerline direction, the void area between the cone member 4 of wedge shape stereochemical structure and burner block 6 front end endoporus increases, and now the velocity of liquid assets of gas medium is accelerated, and flow increases; When driving connecting rod 3 to drive cone member 4 to move forward along burner block 6 centerline direction, the gap between the cone member 4 of wedge shape stereochemical structure and burner block 6 front end endoporus reduces, and now gas medium circulation stream amount diminishes, and slows; Connecting rod 3 runs in trapped orbit, the speed of flexible modulation circulation medium and flow, and then realizes the object controlling furnace pressure.
