Abstract
The utility model relates to a pot-type furnace, and belongs to the technical field of calcining equipment. The pot-type furnace comprises a preheating air channel, wherein the preheating air channel comprises a by-pass pipeline connected with a by-pass valve; and one end of the by-pass pipeline is connected with the preheating air channel. According to the pot-type furnace, the by-pass pipeline is used for leading a section of the preheating air channel to an outer wall; when the content of volatile components in raw material petroleum coke is higher, the pot-type furnace doesn't require or requires a small amount of preheated air, and by the aid of the adjustment and the control of the by-pass valve, the preheated air is led out of a pot-type furnace body successfully; and by the aid of the buoyancy of the preheated air, the effect of utilizing the preheated air to cool coke is very remarkable. The temperature of the led-out preheated air reaches 250 DEG C; the difference of temperatures of the coke before implementation and after implementation is more than 70 DEG C; the temperature of water in a jacket is reduced by about 10 DEG C; the pot-type furnace has certain protection functions for a coke cutter, a belt conveyor and a bucket elevator; and the output of the pot-type furnace can be increased by about 2%.
Description
Technical field
The utility model belongs to the calciner technical field, relates in particular to a kind of can-type calcine furnace.
Background technology
Existing pot furnace preheated air road, principle of work is, utilizes the heat of the refinery coke of high-temperature calcination, indirectly to entering the air that participates in burning in quirk, carries out preheating, effectively utilizes heat energy, improves the temperature of quirk.Current problem is because the volatile content of raw material refinery coke is higher, and fire path temperature, in higher state, as adopted preheated air, can increase fire path temperature, and furnace temperature is too high, and quality product and converter life are had to disadvantageous effect.Existing pot furnace device can be regulated the amount that preheated air is used, even with preheated air, can not realize, but owing to not adopting preheated air, existing device exists can't realize utilizing preheated air to carry out cooling function to the refinery coke of high-temperature calcination, and this function is to improving pot furnace output, reduce the coke discharging temperature, raising coke breaker life-span, reduction water jacket device load have active effect.
The utility model content
For above-mentioned technical problem, the purpose of this utility model is to provide a kind of pot furnace, makes when not needing or reducing and use preheated air to carry out when combustion-supporting, can not change the function of preheated air road cooling coke.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of pot furnace, comprise the preheated air road, and described preheated air road comprises the by-pass line that is connected with by-pass valve, and described by-pass line one end is connected with described preheated air road.
The utility model pot furnace, adopt by-pass line that the preheated air road is drawn to one section to exterior wall, when the volatile matter of raw material refinery coke higher, pot furnace does not need or while needing preheated air on a small quantity, adjusting by by-pass valve is controlled, make preheated air derive smoothly the pot furnace body of heater, due to the buoyancy of preheated air, utilize the effect of preheated air cooling coke very obvious.
The accompanying drawing explanation
Accompanying drawing is the utility model pot furnace structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is made and being further illustrated.
The utility model pot furnace as shown in the figure, preheated air road 1 is provided with arm-tie 4, in the normal situation of raw material volatile fraction in petroleum coke, to be air burnt and heated to body of heater from the volatilization gas of air intlet 5 and raw material refinery coke pot furnace body of heater type of heating, the aperture of simultaneously regulating preheated air road 1 arm-tie 4 makes preheated air enter the pot furnace upper of furnace body from combustion-supporting preheated air import 6, thereby regulate the temperature of body of heater and effectively protect body of heater, when the volatile matter of raw material refinery coke higher, pot furnace does not need or while needing preheated air on a small quantity, by regulating the aperture of preheated air road arm-tie 4, draw one section bypass duct 2 to exterior wall from pot furnace body of heater preheated air road 1, regulate and control bypass duct 2 by by-pass valve 3, preheated air is derived to the pot furnace body of heater smoothly, realization utilizes preheated air to carry out cooling function to the refinery coke of high-temperature calcination, and this function is to improving pot furnace output, reduce the coke discharging temperature, improve the coke breaker life-span, reduce the water jacket device load active effect is arranged.The preheated air temperature of deriving is measured, and temperature reaches 250 degree, more than before and after implementing, coke temperature differs 70 degree.The jacket water (J.W.) water temperature reduces by 10 degree left and right.Can reduce the water consumption of water jacket, coke breaker, conveyor, chapelet are had to certain provide protection.Can improve pot furnace output 2% left and right.
The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; it should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
