The specific embodiment
The utility model will be further described below in conjunction with specification drawings and specific embodiments.
As the solid fuel feedway of Fig. 1 to nonmetal industrial furnace shown in Figure 4, the method that employing dilute phase strength is carried directly sprays into nonmetal industrial furnace burning with the powder of solid carbon fuel, adopted the dilute phase pneumatic conveying method, send (negative pressure) formula to combine with suction with force feed (malleation) formula, this method has that cost is low, and discharge pressure is low, and gas-solid biphase flow mixes, fuel combustion is abundant, energy-conserving and environment-protective.
Realize that the major measure that above-mentioned dilute phase strength is carried is:
As shown in Figure 1, carry powder, carry gas to discharge by top, storehouse filter collector 1 to fuel storage powder storehouse 2.Powder in the fuel storage powder storehouse 2 arrives powder winding-up jar 4 by feed valve 3, after the pressurising pipeline pressurising that the compressed gas-reservoir gas tank 8 of powder in the powder winding-up jar 4 inserts mixes through bottom discharge formula fluidisation conveyer 5 fluidisations again, arrive inspirator mixer 7 by baiting valve 6, described mixer-ejector 7 has top charging aperture 71, bottom air inlet 72, anterior discharging opening 73, rear portion air inlet 74, air inlet screw rod 75, wherein air inlet screw rod 75 can free adjustment length, top charging aperture 71 links to each other with the outlet of baiting valve 6, anterior discharging opening 73 is connected with powder current divider 9, bottom air inlet 72 is connected with compressed gas gas tank 8, and rear portion air inlet 74 also is connected with compressed gas gas tank 8 by air inlet screw rod 75, has guaranteed that effectively powder mixes.Be transported to powder current divider 9 through inspirator mixer 7, powder current divider 9 has some outlets, and the powder uniform distribution exports to each, through solid powder burner 10, burner front end and arm air-flow merge once more, are sprayed onto at last in the industrial furnace 11, and every jar of powder was jetted with the constant time.Powder, belongs to positive-pressure type and carries to inspirator mixer 7 from powder winding-up jar 4, and powder forms a region of no pressure in inspirator mixer 7, send (negative pressure) formula to carry to draw the powder of delivering coal to carrying powder to be mixed to the powder current divider, belong to inhale.Thisly send the method for the conveying of (negative pressure) dilute phase strength that formula combines with suction with force feed (malleation) formula, guaranteed effectively not only that powder fuel carries evenly, stable, continuously, and can control to adjust the winding-up amount of the required powder of each port flexibly.After winding-up finished, powder winding-up jar 4 passed through the diffuse channel pressure release, charging again, pressurising, wait, winding-up after pressure release finishes, and systemic circulation is worked continuously.Carry the winding-up powder to be meant the fuel of solid carbon, comprise petroleum coke powder, coal dust, or the mixed powder of the two, the operation principle that above-mentioned powder is carried and the situation of powder are identical.Because the pumped (conveying) medium that is built-in with bottom discharge formula fluidisation conveyer 5 in the powder winding-up jars 4 diffuse metal web plate around its sidepiece evenly enters, what bottom discharge formula fluidisation conveyer 5 adopted is the bottom discharge form, this effectively guarantees the even mixed distribution of gas-solid biphase flow, and similar liquids equally evenly flows out downwards from eminence then.It is even, stable to have guaranteed that so dusty fuel is carried, continuously.When powder when the inspirator mixer 7, the pumped (conveying) medium that enters from the bottom air inlet of inspirator mixer 7 carries out fluidisation to powder once more, this is more effective, and to have guaranteed that dusty fuel is carried more even, stable more with continuously.The size of tank pressure by regulating powder winding-up jars 4 and the pumped (conveying) medium throughput that enters from the anterior air inlet of inspirator mixer 7 then plays the size of the amount of dusting in the accurate adjusting unit interval.With the constant unit interval by the heat in each port input kiln, thereby stablized the temperature of whole industrial furnace, guaranteed the quality of process of producing product.And the length of flame of solid powder burner 10 ejection is mainly regulated by the adjusting length of the air inlet screw rod 75 of inspirator mixer 7, the length of throughput size fine setting flame that also can be by regulating solid powder burner 10 arms.
This device adopts fuel storage powder storehouse 2 of sealing and powder winding-up jars 4, is transported to the injection system powder all the time airtight environment from powder, and top, storehouse filter collector concentration of emission is less than 30mg/m on the storage powder storehouse
3, system can adopt nitrogen or compressed air to make pumped (conveying) medium, does not have other pernicious gases in the production and enters in the atmosphere, and environmental protection effect is good.
