Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, a kind of multi-tube external-heat fume reverse extraction rotary carbide furnace is provided.
The object of the invention is realized according to following proposal:
A kind of multi-tube external-heat fume reverse extraction rotary carbide furnace; It has a horizontally-inclined revolution body of heater, and the high-end side of body of heater is equipped with hopper, and bottom one side has discharge port and combustion chamber; It is characterized in that having in the body of heater tube bank of annular spread along the cross section; Carbonized material and gas flue are separated, and carbonized material is walked tube side, and flue gas is walked shell side;
In the high-end side of body of heater flue gas second stage employ device is installed, is used in the body of heater that the current tube side of carbonized material is high-end to link to each other with hopper, low side links to each other with discharge port, is used for the high termination flue gas of the shell side second stage employ device that flue gas passes through, and hangs down the termination combustion chamber;
Above-mentioned flue gas second stage employ device has an incinerator that links to each other with the body of heater shell side, and waste heat boiler is equipped with in the incinerator top, and dedusting trap, the external chimney of dedusting trap are equipped with in the waste heat boiler top;
Above-mentioned combustion chamber is provided with fuel door, and the slagging-off storehouse is arranged at the bottom, combustion chamber, and the slagging-off storehouse is provided with the slag door.
The present invention compared with prior art has following characteristics:
The first, body of heater socket of the present invention is when utilizing the fugitive constituent heat output; Also saved this part fuel cost that needs, so also reduced the slag stacking, it has been burnt at incinerator heat again to waste heat boiler; Save the desired fuel of system steam, reached purpose of energy saving like this.
The second, fugitive constituent and gas fume of combustion chamber are withdrawn into the shell side burning together, and fugitive constituent is self-temperature very high (more than 700 ℃) at the discharge port place, itself carries heat when drawing back and can be utilized again by carbonized material; Can be reached 650 ℃ by temperature of combustion by secondary in the combustion chamber, last flue gas and fugitive constituent remainder arrive about 240 ℃ of floss holes, get into incinerator and are further burnt; The heat that produces heats to preboiler; The steam that produces can also be can be used for activation by charring furnace self utilization, and through burning several times, the heat in the flue gas is utilized once more; Objectionable constituent are wherein all burnt, and discharging also can reach standard.
The 3rd, through repeatedly the charing fugitive constituent being burnt, after the whole or most burnings of objectionable constituent wherein, the discharging environmental pollution reduces greatly.
The 4th, charring furnace moves in semi-closed system, has reduced the discharging (few partial fume being arranged along with carbonized material is emerged in the exit) of flue gas at operation room, makes that the operation workshop is clean, helps the healthy of operator and can the operation environment.
The 5th, the charing operation of shell and tube, the heat that makes carbonized material and fuel produce separates; Avoid charing problem too, in addition, when flue gas is taken out, also avoided the coal tar in the fugitive constituent to adhere to the carbonized material surface once more; Make product appearance not bright and clean, also can influence activation effect simultaneously.
