The arrangement of heat exchanger tube in the utility model, combination design according to the needs of heat exchange area, and be divided into low-temperature zone (near inlet of cold air) and high temperature section (advancing hot air outlet), in factory's overall package in casing, good airproof performance, heat-transfer surface Pipe bundle structure compactness, reduce steel consumption, on-the-spot installation is simple and convenient.
On the basis of such scheme, in every snakelike heat exchange tube, some heat exchanger tubes are indentation from top to bottom and arrange.So tortuous design can make heat exchanger tube up and down compact more, can also dwindle the volume of heater.
The beneficial effects of the utility model are:
1, heat exchanger tube is made up of seamless steel pipe winding screw fin, has heat exchange property efficiently, thermal efficiency height;
2, the two ends of all heat exchanger tubes are supported by tube sheet, and an end fixed support, the other end float and support, and pipe is heated can free wxpansion, and reliable in structure is difficult for causing steam leakage because of the pipe expanded by heating booster that is obstructed;
3, casing is wrapped in heat exchanger tube and complete air chamber of tube sheet composition, good seal performance.
4, the arrangement of heat exchanger tube, combination design according to the needs of the air capacity (or heat exchange area) of need heating, and are divided into low-temperature zone and high temperature section, make full use of the condensation characteristic exotherm of steam, reach energy-saving and cost-reducing effect;
5, in factory's overall package in casing, good airproof performance, heat-transfer surface Pipe bundle structure compactness reduces steel consumption, on-the-spot install simple and convenient;
6, the stability of this equipment, reliability directly have influence on the black-liquor combustion effect of alkali recovery boiler, are to guarantee the alkali recovery boiler smooth combustion basis of operation continuously.
