Description
Technical field
The utility model relates to a kind of compensator, is specifically related to a kind of preheater single tube compensator for carbon black smoke cooling.
Background technique
In production of carbon black, the high temperature carbon black smoke of more than 800 DEG C being produced from reaction furnace, in order to effectively utilize the heat energy entrained by high temperature carbon black smoke, generally all this high-temperature flue gas being carried out cooling process by tube still type air preheater.See Fig. 1, high-temperature flue gas passes in the heat exchanging tube 1 of preheater, and cryogen enters from cryogenic gas entrance 2, and circulate outside heat exchanging tube 1 cryogen, and by the heat exchange with high-temperature flue gas, cryogen is raised by heating-up temperature, and flue-gas temperature reduces simultaneously.The expansion of pipe in the tube bank caused in order to the thermal expansion absorbed between high temperature tube bank with the inner casing of relatively lower temp and the tube bank fouling caused due to flue gas particle, every root heat exchanging tube 1 couples together with upper perforated plate 6 by calandria preheater using compensation device 8.
The structure of existing compensator comprises the sheathed internal lining pipe of concentric gap 4, bellows 3 and protective casing 5; internal lining pipe 4 is sheathed in bellows 3; protective casing 5 is set in outside bellows 3; bellows 3 lower end is welded with internal lining pipe 4 lower end; upper end is welded with protective casing 5 upper end; protective casing 5 is fixed on upper perforated plate 6 through preheater upper perforated plate, and the effect of protective casing positions bellows, prevents bellows by airflow scouring simultaneously.But because existing protective casing is enclosed construction, what pass in compensator is high-temperature gas, and is unfavorable for the heat radiation of compensator, reduces the working life of compensator.
Model utility content
The purpose of this utility model is just for above-mentioned the deficiencies in the prior art; a kind of tube still type air preheater single tube compensator for carbon black smoke cooling is provided; it can realize the heat radiation for bellows; improve the working life of compensator, also can not affect the protective capability of protective casing for airflow scouring and the heat transfer effect of preheater.
To achieve these goals, the technical solution adopted in the utility model is such:
A kind of preheater single tube compensator for carbon black smoke cooling, comprise the internal lining pipe that concentric gap is sheathed, bellows and protective casing, internal lining pipe is sheathed in bellows, protective casing is set in outside bellows, bellows lower end is welded with internal lining pipe lower end, upper end is welded with protective casing upper end, protective casing is fixed on upper perforated plate through preheater upper perforated plate, it is characterized in that: described protective casing comprises relative air-flow subtend pipe face, the direction of the low-temperature airflow passed into preheater and the air-flow identical with the direction of the low-temperature airflow that preheater passes into pipe face in the same way, described air-flow subtend pipe face arranges radiation hole, the position height of described radiation hole is lower than the position of preheater upper head plate.
Further; described air-flow subtend pipe face and air-flow in the same way pipe face divide with the axial slices of protective casing; ensure that the half area in protective casing pipe face is the area in air-flow subtend pipe face; thus radiation hole is processed in a semicanal face areal extent of protective casing, ensure that protective casing reaches maximum radiating effect and low-temperature airflow also can not be made to wash away bellows by radiation hole simultaneously.
Further, described radiation hole is elongated hole, and it is level and smooth that elongated hole design is convenient to carry out polishing to protective casing interior surface, can not hurt bellows.
Preferably, said flow subtend pipe face is spaced several radiation hole is set, to strengthen radiating effect.
Compared with prior art, the air-flow subtend pipe face that the protective casing of existing compensator is divided into the direction of the low-temperature airflow passed into preheater relative by the utility model and the air-flow identical with the direction of the low-temperature airflow that preheater passes into pipe face in the same way, air-flow subtend pipe face arranges radiation hole to reach the effect making bellows dispel the heat, simultaneously because air-flow subtend pipe face is relative with the direction of preheater low-temperature airflow, block low-temperature airflow to be washed away bellows by radiation hole, and radiation hole is arranged on below preheater upper perforated plate, air-flow can not be overflowed from upper perforated plate by radiation hole, ensure that the air-flow enclosed environment in preheater, ensure that heat transfer effect, therefore the utility model can reach compensator protective casing and makes bellows carry out the effect of dispelling the heat, improve the working life of compensator, also the protective capability of protective casing for airflow scouring and the heat transfer effect of preheater can not be affected.
