Abstract
The utility model provides a double-element thermal compensation tube-and-plate type high-temperature air preheater, comprising a shell, an air-out smoke box, an air-in smoke box, an upper tube plate, a lower tube plate, baffles, bypass baffles, heat exchanging tubes, transitional casing tubes, a monotube compensator and a protective cover. The shell is provided with an air inlet, an air outlet and a barrel body compensator. The air-out smoke box and the air-in smoke box are connected with the two ends of the shell. The upper tube plate, the lower tube plate, the baffles, the bypass baffles and the heat exchanging tubes are arranged in the shell. The transitional casing tubes are positioned at the connecting points of the upper tube plate, the lower tube plate and the heat exchanging tubes. The monotube compensator is arranged on the heat exchange tubes. The protective cover is connected with the upper tube plate and is arranged at the outside of the monotube compensator. The utility model has the advantages of high thermal efficiency, high air-preheating temperature and long service life. The utility model can prevent all regional thermal temperature difference stresses of a tube side and a shell side damaging the equipment of the utility model.
Description
The utility model relates to a kind of heat-exchanger rig, particularly relates to a kind of double base thermal compensation tube-sheet type high-temperature air preheater.
The tube-sheet type high-temperature air preheater is the visual plant in the production of carbon black.General employing is no thermal compensation tube-sheet type preheater or unit thermal compensation tube-sheet type preheater at present.The former does not in use wait because of high-temperature flue gas can cause tube side and each position thermal expansion amount of shell side owing to no expansion loop, thereby forms thermal (temperature difference) stress, causes device damage, breaks as tube sheet and heat exchanger tube junction.The latter is provided with the cylindrical shell compensator on housing; or Chinese patent 88208702.9 is disclosed such; the protection bushing pipe of being made up of front tube, pipe platform and rear end pipe is set at the heat exchange mouth of pipe; and make of nonmetallic materials; this protection bushing pipe is similar to the refractory layer material; the homogeneous that expands under the hot operation situation is avoided the refractory layer be full of cracks.In addition protection bushing pipe in aspect inserts the heat exchange mouth of pipe, has slowed down the stress of tube sheet, mouth of pipe welding and has concentrated, and avoids high-temperature gas to contact with the direct of heat exchange nose end.But still can not prevent that each position thermal expansion amount of heat exchanger tube from not waiting the damage to equipment of the thermal (temperature difference) stress that produced.
The purpose of this utility model is to provide a kind of heat exchange efficiency height, and the double base thermal compensation tube-sheet type high-temperature air preheater of long service life.
The utility model double base thermal compensation tube-sheet type high-temperature air preheater is to realize like this, it comprises the housing that is provided with air inlet and outlet, the smoke box of giving vent to anger that is connected with the housing upper end, the air inlet smoke box that is connected with the housing lower end, be installed in the cylindrical shell compensator on the housing, be arranged on upper and lower tube sheet, deflection plate, by-pass damper and heat exchanger tube in the housing, be positioned at the transition spool piece of upper and lower tube sheet and heat exchanger junction, be arranged on the single tube compensator on the heat exchanger tube, and be connected and the protective cover outside the single tube compensator with upper perforated plate.Wherein deflection plate is for becoming spacing multilayer deflection plate.The single tube compensator is made up of with the bellows that corrugated header and transition spool piece are connected respectively with two ends the corrugated header that is connected with heat exchanger tube.There is aperture at facing the wind district and the place, leeward district of protective cover, are used to prevent hot-air to the washing away of bellows, and the while can be cooled off bellows again.
The course of work of the utility model double base thermal compensation tube-sheet type high-temperature air preheater is that high-temperature flue gas enters the heat exchanger tube from the air inlet smoke box, enters process pipe from the smoke box of giving vent to anger again.Cold air is entered in the housing by air intlet, circuitous the flowing in housing through deflection plate and by-pass damper, and the heat absorption back enters process pipe from air outlet slit, simultaneously the cooling heat transferring pipe.Heat exchanger tube combines compensation with the thermal expansion amount of housing by single tube compensator and cylindrical shell compensator.
The advantage of the utility model double base thermal compensation tube-sheet type high-temperature air preheater is the heat exchange efficiency height, make the gas approach temperature bring up to 850 ℃, air themperature after the preheating is brought up to 650 ℃ by existing 450 ℃, and prevented of the damage of the thermal (temperature difference) stress of tube side and shell side effectively to equipment, prolonged the service life of equipment, energy-saving effect is remarkable.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
Fig. 1: the utility model structural representation
Fig. 2: single tube compensator schematic diagram
The utility model double base thermal compensation tube-sheet type high-temperature air preheater comprises the housing 1 that has air intlet 4 and outlet 5, give vent to anger smoke box 2 and the air inlet smoke box 3 that is connected with housing 1 two ends respectively, be arranged on the cylindrical shell compensator 6 on the housing 1, be installed in upper and lower tube sheet 7 and 8, deflection plate 9, by-pass damper 10 and heat exchanger tube 11 in the housing 1, be positioned at the filtration sleeve pipe 12 of heat exchanger tube 11 and upper perforated plate 7, lower perforated plate 8, junction, be arranged on the single tube compensator 13 on the heat exchanger tube 11, and be connected with upper perforated plate 7 and be positioned at the outer protective cover 14 of single tube compensator 13.Wherein single tube compensator 13 reaches bellows 16 compositions that two ends are connected with corrugated header 15, upper perforated plate 7 respectively by the corrugated header 15 that is connected with heat exchanger tube 11.
