Abstract
The utility model relates to an insulating device for the coal-feeding tower of a coke oven, composed of a centrifugal type draught fan, and a slot-shaped insulating slot provided with closed periphery and flat bottom, which are connected with a pipe, wherein, the insulating slot bottom is provided with an opening for forcing a coal outlet at the conical bottom of the coal-feeding tower to extend out, the lateral side of the insulating slot is provided with a flue gas inlet, and the outlet of the draught fan and the flue gas inlet of the insulating slot are connected through a pipe. The insulating slot can cover the conical bottom of the coal-feeding tower, and the draught fan can send the flue gas generated at the bottom of the flue gas chimney of the coke oven to the insulating slot wrapped by the conical bottom of the coal-feeding coal to preserve the heat of the coal-feeding tower with the flue gas. The utility model can be used for preserving heat of the coke oven with the flue gas, can not burn the coal-feeding tower and can save energy.
Description
The utility model relates to the attemperator of the coal tower in the coke oven production.
Coal tower in the coke oven production unit is to build bunker at the bottom of the outdoor awl made from Steel Concrete in, and metal coal outlet is arranged at the bottom of the awl of coal tower.In the winter of north cold, coal in awl bottom and the coal outlet is frozen into piece easily because of containing small amount of moisture, coal is not flow out from awl end coal outlet, and influence is produced, in order to prevent that the coal of boring in bottom and the coal outlet part from freezing, be to the awl bottom and the coal outlet heat tracing of coal tower.In the prior art, useful burning coal gas is incubated the coal tower with the method for flame baking awl bottom and coal outlet part, is incubated the infringement of coal tower very big in this way; Also have at the bottom of the awl of coal tower and coal outlet partly be surrounded by insulation groove or serpentine tube, in insulation groove or serpentine tube, feed water vapor during use, to the insulation of coal tower, it is very big to be incubated energy consumption in this way.
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind of coke oven coal tower attemperator of not only having saved the energy but also not damaged coke oven coal tower.
The utility model is realized with the following method.
The invention scheme of coke oven coal tower attemperator is the insulation groove that closed perimeter is arranged that is surrounded by the flute profile made from steel plate at the bottom of the awl of coal tower, the epimere of the awl of coal tower bottom and coal outlet is encased, with blower fan the high-temperature flue waste gas of discharging in the coke oven production is fed in the insulation groove, realize insulation the coal tower.
For realizing the foregoing invention scheme, coke oven coal tower attemperator is made up of with pipe connection the insulation groove by closed perimeter of induced draft fan and flute profile.
Induced draft fan is a centrifugal fan, the insulation groove is the flat pan made from steel plate, the insulation notch is identical with the peripheral shape that the coal tower is bored the end, the insulation bottom land has opening, the insulation groove can encase the awl bottom of coal tower, and after the insulation groove wrapped in the awl bottom of coal tower, the coal outlet of coal tower can stretch out from the opening of bottom land, the side of insulation groove has the waste gas inlet, is connected with pipeline between the outlet of induced draft fan and the waste gas inlet that is incubated groove.
During installation, the inlet of induced draft fan is connected with pipeline with the stack gases chimney bottom of coke oven.The insulation groove is wrapped in the awl bottom of coal tower, allow the coal outlet of coal tower from the opening of insulation bottom land, stretch out one section, after the installation, between notch and the coal tower awl bottom of insulation groove, between the open circumferential of insulation bottom land and the coal outlet that the coal tower is bored the end exhaust clearance is arranged.
During use, induced draft fan is drawn high-temperature flue waste gas from coke oven flue waste stack bottom, send in the coal tower awl insulation groove at the end by pipeline, with stack gases coal tower awl bottom and coal outlet heat tracing, the stack gases behind the heat tracing from the notch periphery of insulation groove and coal tower awl bottom with exhaust clearance and be incubated the open circumferential of bottom land and the coal outlet of coal tower bottom boring between exhaust clearance discharge.
Adopt the utility model can realize,, also saved the energy the not infringement of coal tower with the heat tracing of stack gases to coke oven coal tower.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the synoptic diagram of coke oven coal tower attemperator.
Among Fig. 1, coke oven coal tower attemperator is connected to form by induced draft fan 1, insulation groove 2 usefulness pipelines 3.
Induced draft fan 1 is a centrifugal fan, and induced draft fan 1 can be driven by its electric motor 11 and rotate.
After coke oven coal tower attemperator was installed, the inlet 12 of induced draft fan 1 was connected with pipeline 51 with the bottom of coke oven flue waste stack 5.Insulation groove 2 wraps in coal tower awl at the end 4, after insulation groove 2 wraps at the bottom of the awl of coal tower on 4, the hypomere of the coal outlet 41 at the coal tower awl end stretches out from the insulation groove opening 21 at 2 ends, its epimere wraps in the insulation groove, the notch periphery of insulation groove 2 has exhaust clearance 42 with coal tower awl bottom surface, between the open circumferential of insulation bottom land and the coal outlet 41 of coal tower exhaust clearance 43 is arranged also.
