The calcined petroleum coke high-temperature gas treatment plant ensures that the unburned volatile in the high-temperature gas is completely burnt, ensures that the gas temperature at the outlet of the chamber does not exceed the set value, and reduces the powder content in the treated high-temperature gas.
Description
Technical field
The utility model relates to the device that a kind of calcined petroleum coke high-temperature flue gas is handled, and relates in particular to metallurgy, chemical industry calcining refinery coke by rotary kiln high-temperature flue gas treating apparatus.
Technical background
The main raw material(s) that calcined petroleum coke is produced as carbon product has a wide range of applications in carbon industry.Because rotary kiln has simple in structure, automatization level advantages of higher, and becomes the calcining petroleum coke mode that most of enterprise adopts.Petroleum coke is in rotary kiln in the high-temperature calcination processing procedure, can produce a large amount of high-temperature flue gas, contain the unburned fugitive constituent of part and a spot of petroleum coke coke powder in these high-temperature flue gas, at present generally adopt the method for gravity settling chamber or combustion chamber that these high-temperature flue gas are handled, there is following problem in the treating apparatus of these two kinds of high-temperature flue gas:
1, the gravity settling chamber flue gas treating process can only play the effect of dust in the sedimentation high-temp waste gas, the unburned fugitive constituent that enters expansion chamber can not be burnt on the one hand; The gravity settling chamber dust-collecting efficiency is not high yet on the other hand;
Although 2, current gas fume of combustion chamber treatment process can fall into into the fugitive constituent in the combustion chamber in partial combustion, but owing to there is not actual burning control, therefore also can't guarantee the abundant burning of fugitive constituent in the high-temp waste gas, also can't control effectively simultaneously the combustor exit flue-gas temperature.
The utility model content
The utility model is that a kind of calcining refinery coke by rotary kiln high-temperature flue gas treating apparatus is provided in order to address the above problem, and its objective is to guarantee unburned fugitive constituent completing combustion in the high-temperature flue gas; The flue-gas temperature that guarantees combustor exit is no more than setting value; Reduce the dust content of handling in the high-temperature flue gas of back.
In order to address the above problem, the utility model is achieved in that
Calcining refinery coke by rotary kiln high-temperature flue gas treating apparatus comprises the combustion chamber, is provided with fuel nozzle at the combustion chamber high temperature smoke inlet, is provided with air-introduced machine at the combustion chamber high temperature exhanst gas outlet, and the end in the combustion chamber is provided with thermometric, oxygen determination gas content device.
Described temperature measuring equipment is a temperature thermocouple.
Described oxygen determination gas content device is the oxygen content analyzer.
The front end of described combustion chamber is provided with combustion fan.
Described combustion fan is an air blast.
Described combustion chamber diameter is that 5～7m, length are 50～80m.
The utility model has the advantages of: guarantee unburned fugitive constituent completing combustion in the high-temperature flue gas; The flue-gas temperature that guarantees combustor exit is no more than setting value; Reduce the dust content of handling in the high-temperature flue gas of back.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, combustion chamber; 2, combustion fan; 3, wind blower fan; 4, fuel nozzle; 5, oxygen content analyzer; 6, thermocouple; 7, air-introduced machine.
The specific embodiment
Below embodiment of the present utility model is described in detail in conjunction with the accompanying drawings, but protection domain of the present utility model is not limit by embodiment.
As shown in Figure 1, the device that the calcining refinery coke by rotary kiln high-temperature flue gas is handled, structure is as follows: it comprises combustion chamber 1, combustion chamber 1 diameter is that 5～7m, length are 50～80m, and to be provided with 4, wind blower fans of fuel nozzle 3 be fuel nozzle 4 air feeds to 1 high-temperature flue gas entry in the combustion chamber, the outlet of 1 high-temperature flue gas is provided with air-introduced machine 7 in the combustion chamber, high-temperature flue gas is drawn combustion chamber 1 under the effect of air-introduced machine 7, keep the negative pressure in the combustion chamber 1; 1 end is provided with temperature measuring equipment in the combustion chamber, and temperature measuring equipment is a thermocouple 6; 1 end is provided with the oxygen content of smoke gas testing arrangement in the combustion chamber, and detecting oxygen device is an oxygen analysis instrument 5; 1 front end is provided with combustion fan 2 in the combustion chamber, and combustion fan 2 is an air blast.
Operation principle of the present utility model is as follows: combustion chamber 1 is out of service and when starting, and keeps temperature in the combustion chamber 1 by the fuel combustions of ejection in the fuel nozzle 4 of control combustion chamber 1 high-temperature flue gas upstream end; Measure the temperature of combustion chamber 1 outlet high-temperature flue gas and the oxygen content in the flue gas, regulate the wind supply quantity of combustion fan 2; High-temperature flue gas is drawn combustion chamber 1.The temperature and the oxygen content thereof of combustion chamber 1 outlet high-temperature flue gas are to measure by the thermocouple 6 and the oxygen content analyzer 5 of combustion chamber 1 smoke outlet, when the outlet high-temperature flue-gas that thermocouple 6 is measured is lower than combustion chamber 1 exit gas temperature setting value, by the oxygen analysis instrument oxygen content in the high-temperature flue gas is analyzed, and the wind supply quantity of regulating combustion fan 2 guarantees to export oxygen content in the high-temperature flue gas in setting range, to guarantee the abundant burning of fugitive constituent in the high-temperature flue gas; The outlet high-temperature flue-gas of thermocouple measurement, when being not less than combustor exit high-temperature flue-gas setting value, no longer the oxygen content in the control outlet flue gas only adds excess air by combustion fan and reduces exit gas temperature.
