Abstract
The invention discloses a combustion device for processing calcined petroleum coke smoke, particularly relates to a combustion device for processing calcined petroleum coke smoke of a rotary kiln. The combustion device for processing the calcined petroleum coke smoke of the rotary kiln comprises a combustion chamber, a smoke inlet and a smoke outlet, wherein a dust collecting device is arranged at the lower end of the combustion chamber of vertical cylindrical shape. A fuel burner, an air supply duct and a combustion air fan are arranged on the combustion chamber, wherein the combustion air fan is connected with the air supply duct through a pipeline, and the air supply duct is installed on the middle and lower portion of the combustion chamber. A horizontal smoke combustion chamber in prior art is changed to a vertical cylindrical smoke combustion chamber, different components are reasonably arranged, and the structure is simple, so that the covering area of the device is greatly reduced, the production costs are also reduced, and the settlement and collection of dust is facilitated. Furthermore, the high-temperature smoke discharged by the combustion device can be recycled, and a steam generator set can be installed behind the combustion chamber to make full use of the smoke waste heat, thereby achieving the effects of energy saving and environment protecting.
Description
Technical field
The present invention relates to a kind of burner of processing the calcined petroleum coke flue gas, relate in particular to a kind of burner of processing the calcining refinery coke by rotary kiln flue gas.
Background technology
Calcined petroleum coke is the important source material of carbon product.In the process that petroleum coke is calcined, can produce a large amount of high-temperature flue gas in rotary kiln, contain the combustible that comprises coke dust and volatile matter in these flue gases, must could discharge after treatment.The general method that adopts is that volatile matter and carbon dust in burner that flue gas is contained consumes.Because volatile matter and carbon dust burning can discharge amount of heat, so this burner does not need additionally to provide fuel, the carrying out that the heat that only relies on flue gas self burning to produce can be kept reaction.
At present smoke combustion device commonly used is horizontal type structure, has that floor space is large, equipment volume is huge, the high in cost of production shortcoming.Some special device is made bending shape with combustion chamber anyhow, but it still is horizontal type structure generally, and there is cost technical problem high, difficult in maintenance in the burner of this bending shape structure.Existing smoke combustion device also exists each parts that irrational problem is set.Therefore, develop a kind of simple in structure, floor space is little, rational smoke combustion device is set is the technical problem that present those skilled in the art are badly in need of solving.
Summary of the invention
The object of the invention is to solve the existing problem of above-mentioned horizontal equipment, provide a kind of simple in structure, floor space is little, the burner of rational processing calcining refinery coke by rotary kiln flue gas is set.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of burner of calcining refinery coke by rotary kiln flue gas, it comprises combustion chamber, smoke inlet, exhanst gas outlet, wherein the lower end of combustion chamber is provided with dust collect plant, the combustion chamber is for vertically cylindrical, be provided with fuel nozzle, air on the combustion chamber for airduct, combustion fan is connected for airduct with air by pipeline, and air is arranged on the middle and lower part of combustion chamber for airduct.
Be provided with refractory lining on the inwall of above-mentioned combustion chamber.
The bottom of above-mentioned combustion chamber is provided with support.
Be provided with peep hole on the above-mentioned combustion chamber.
Above-mentioned peep hole is 2-6, wherein has one to be arranged on air for the next door of airduct.
Above-mentioned fuel nozzle and smoke inlet are arranged on the same level position of combustion chamber.
Owing to adopting technique scheme, so that the present invention has following advantage and effect: change into the smoke combustion chamber of horizontal type vertically cylindrical, all parts arranges rationally, simple in structure, greatly reduced occupation area of equipment, reduce production cost, and more be conducive to sedimentation and the collection of dust.Simultaneously, the high-temperature flue gas that burner is discharged can be recycled, can after connect the steam-electric power unit, fume afterheat is taken full advantage of, reach the effect of energy-conserving and environment-protective.

The specific embodiment
The below is described in detail by reference to the accompanying drawings to embodiments of the invention, but protection scope of the present invention is not limit by embodiment.
As shown in Figure 1, the burner of a kind of calcining refinery coke by rotary kiln flue gas of the present invention, it comprises combustion chamber 3, smoke inlet 1, exhanst gas outlet 2, and wherein the lower end of combustion chamber 3 is provided with dust collect plant 4, and dust collect plant 4 will be deposited in coke dust and the ash content of bottom of device and remove.Be provided with refractory lining on the inwall of combustion chamber 3, combustion chamber 3 is for vertically cylindrical, the bottom of combustion chamber 3 is provided with support 9, support 9 plays the effect of supporting combustion chamber 3, be provided with fuel nozzle 5, air on the combustion chamber 3 for airduct 6 and peep hole 8, combustion fan 7 is connected for airduct 6 with air by pipeline, for smoke combustion provides the capacity air.Air is arranged on the middle and lower part of combustion chamber 3 for airduct 6.Peep hole 8 is 2-6, wherein has one to be arranged on air for the next door of airduct 6.Fuel nozzle 5 and smoke inlet 1 are arranged on the same level position of combustion chamber 3.
The burner of calcining refinery coke by rotary kiln flue gas of the present invention, it is arranged on the rotary kiln flue gas and gathers the place, is used for the flue gas that calcining refinery coke by rotary kiln produces is burnt and sedimentation, to reduce the pollution to environment.The flue-gas temperature that rotary kiln is discharged is about 800 ℃, and they enter combustion chamber 3 by smoke inlet 1, carry out combustion reaction in combustion chamber 3, discharges from exhanst gas outlet 2 at last.Under normal running (operation) conditions, air is blasted by combustion fan 7 and participates in combustion reaction in the combustion chamber.The carrying out that the heat that volatile matter and coke dust combustion process produce just is enough to keep burning do not need extra fuel to supply with.When combustion apparatus need to start or during preheating (rotary kiln does not move), can provide fuel for combustion chamber 3 by the fuel nozzle 5 that is installed on the combustion chamber.Can observe the smoke combustion situation by each peep hole 8 that is arranged on the combustion chamber.
