Description

A kind of gyration formula gas heat exchange system

Technical field

The invention belongs to technical field of heat exchange, is related to gas heat exchange system, specifically a kind of gyration formula gas Heat-exchange device.

Background technology

Heat exchange is carried out between the gas of two kinds of different temperatures, the pipe for boiler exhaust gas heat recovery is common are Regenerative air heater and rotary regenerative air preheater.The structure of both air heat exchangers is different, and tubular air preheater is The hot cigarette of high temperature is flow through from Bottomhole pressure, the air of low temperature from pipe is outer, and both carry out heat convection by tube wall;Swinging air The cylindrical accumulator plate that preheater does gyration by fan housing, petticoat pipe and around center rotor is constituted, and its heat exchange principle is to utilize to turn Gyration of the son between fan housing, petticoat pipe, the air of the heat transfer that heat accumulation plate is absorbed in high temperature cigarette side to low temperature side So as to realize heat exchange.They all have ash cutting, blocking, cold end corrosion, hot air leak rate of air curtain height etc. in actual use and lack Fall into.

A kind of new gas heat-exchange device is explored, is technical task urgently to be resolved hurrily at present.

The content of the invention

The purpose of the invention is that existing air preheater is improved, and develops a kind of gyration formula gas heat exchange dress Put, existing tubular air preheater or the above-mentioned many defects of rotary regenerative air preheater can be avoided.

A kind of gyration formula gas heat exchange system of the adopted the technical scheme that design of the invention, its structure include: Heat accumulation plate, using being rotated between axle arranging the transmission guipure of gyration in two masters, heat accumulation plate is adopted for drive mechanism, wherein drive mechanism Vertical, parallel, dense arrangement is arranged on the transmission guipure of gyration with heat accumulation plate, gyration heat accumulation plate row, gyration heat accumulation plate row is constituted The flue for being arranged on high-temperature flue gas is intersegmental, arranges two outer ends in the heat accumulation plate for entering cigarette section, smoke section and gyration of flue and sets respectively End enclosure is put, it is respectively provided with internal partition in two rotary shaft inner ends and end enclosure, enter the cigarette section, flue of flue goes out The circular passage of gyration heat accumulation plate row is formed between cigarette section, two secondary end enclosures and internal partition, circular passage is divided by heat accumulation plate Arrange the middle part middle part heat exchange zone that communicates with flue of heat accumulation plate for gyration heat accumulation plate, the heat accumulation plate at two ends respectively with end enclosure, Left side closing heat exchange zone between internal partition, right side closing heat exchange zone are closed with left side on the shell of both ends respectively Heat exchange zone, right side closing heat exchange zone connection relative set Cryogenic air inlet pipeline and intensification air discharge pipe.

The heat accumulation plate of the heat accumulation plate row is tortuous.

The transmission guipure can also be chain belt, crawler belt etc..

The invention is used using this gyration formula gas heat exchange system designed by above-mentioned technical proposal and measure When, the high-temperature flue gas installed in boiler flue are intersegmental, and high-temperature flue gas enter cigarette section into middle part heat exchange zone, high-temperature flue gas from flue Corresponding levels heat accumulation plate is transferred heat to, the flue gas after cooling is discharged from flue smoke section;Cryogenic air is respectively from entering Mouth pipeline enters left side closing heat exchange zone, right side closing heat exchange zone, and the heat accumulation plate of gyration will store receipts in middle part heat exchange zone Heat be released to respectively into arranged on left and right sides close heat exchange zone in Cryogenic air, Cryogenic air heat up after from discharge pipe Road is discharged, and after the heat exchange of levels heat accumulation plate, gyration, to middle part heat exchange zone accumulation of heat, so recycles the height of air flue emission again Warm fume afterheat, is continuously discharged heat, accumulation of heat, this gyration formula gas heat exchange system and prior art phase to Cryogenic air Than with being prevented effectively from the ash cutting that tubular air preheater or rotary regenerative air preheater are present, blocking, low temperature are rotten Erosion, hot high defect of leaking out, while also having small volume, arrangement is convenient, and gyration speed is adjustable, and gas converting heat effect is improved etc. Remarkable advantage.
