In, by VFC rotary feeder 2, the flow for adjusting high-temperature semi-coke is 6.77t/h.The high temperature that rotary feeder 2 is discharged
Semicoke is fallen into inflation Fluidizer 3.Gas pipeline inputs carrier gas into inflation Fluidizer, inflation accelerator and blowing pipeline device.
The carrier gas selection is 99.99 vol% nitrogen, is 1210 Nm3/h by governor valve control carrier gas flux, nebulizer gas pressure is
0.5 MPa, temperature are 40 DEG C.High-temperature semi-coke is blowed in receiving warehouse through feeding pipe.The horizontal transport distance of feeding pipe≤
40m, vertical transport distance≤50m.Obtained through measurement, when new type high temperature semicoke air-transport system provided by the invention conveys
Solid-gas ratio be 4.29, reach Condensed transportation；The high-temperature semi-coke temperature for being transported to receiving warehouse entrance is 715.3 DEG C, course of conveying
In preferably maintain the temperature of high-temperature semi-coke, semicoke thermal loss is small, and heat utilization ratio is up to 81.40%.
New type high temperature semicoke air-transport system provided by the invention, all particle diameters of pyrolysis oven discharge can be handled in 0-
10mm high-temperature semi-coke, and can keep the temperature of semicoke, semicoke thermal loss is small in course of conveying, avoid because of cooling semicoke and
The influence to caused by semicoke quality, heat utilization ratio are high；The quantity of rotating machinery is greatly reduced, is neither limited by fed distance
System, reduce again because sealing problem causes leakage, scald, the probability of the even accident such as fire explosion occurs；Biography has been greatly optimized
System air-transport system, introduces charger, eliminates solid pump and a large amount of hand valves, make high-temperature semi-coke quilt under fluidized state
Conveying, improves solid-gas ratio and instantaneous conveying capacity, reduces the consumption of delivery of carrier gas, and Condensed transportation can be achieved；Flow is simple,
It is easily controllable, conveying capacity is big, air consumption is few, economy is substantially dominant；With the conveying of frequency conversion rotary feeder control high-temperature semi-coke
Amount, easily controllable and regulation, excessive, uncontrollable because of discharge quantity it will not cause to block feeding pipe, rotary feeder also has
The effect of gas is locked, prevents that delivery of carrier gas is up, influences the reaction in equipment before rotary feeder；With governor valve control delivery of carrier gas
Flow, while fluid effect is ensured as far as possible reduce load volume, prevent the excessive damage charger of tolerance, simplify system
Flow, reduce plant investment and error rate；All feeding pipes of the system are lined with Wear-resistant heat insulation refractory liner, heat-insulated
While preventing scald personnel, the characteristics such as also resistance to erosion, thermal conductivity factor be low, heat utilization ratio is favorably improved.
