Abstract
The invention belongs to the technical field of heat exchange and particularly relates to a rotation-drive type gas-heat exchange device. The rotation-drive type gas-heat exchange device is mainly characterized in that an existing air preheater is improved, heat storage plate rows are arranged on a rotation-drive transmission mesh belt, and the rotation-drive heat storage plate rows are arranged among flue segments of high-temperature flue gas, an annular channel is formed among the flue segments, end shells and internal partition plates, and the heat storage plate rows divide the annular channel into a middle sealed heat exchange region, a left sealed heat exchange region and a right sealed heat exchange region; the two end shells are communicated with the corresponding two sealed heat exchange regions respectively and low-temperature air inlet pipes and temperature rising air outlet pipes are correspondingly arranged. Compared with the prior art, the rotation-drive type gas-heat exchange device has the remarkable beneficial effects that fly ash wear and low-temperature corrosion can be avoided effectively, the thermal state air leakage rate is low, the size is small, arrangement is convenient, the rotation drive speed is adjustable, and the gas heat exchange effect is improved.
Description
Technical field
The invention belongs to technical field of heat exchange, relates to gas heat exchange system, specifically a kind of gyration formula gas heat exchange system.
Background technology
Carry out heat exchange between the gas of two kinds of different temperatures, common are the tubular air preheater for boiler exhaust gas heat recovery and rotary regenerative air preheater.The structure of these two kinds of air heat exchangers is different, tubular air preheater be the hot cigarette of high temperature from Bottomhole pressure, the air of low temperature flows through from pipe, and both carry out heat convection by tube wall; Rotary regenerative air preheater is by fan housing, petticoat pipe and form around the cylindrical accumulator plate that center rotor does gyration, its heat exchange principle utilizes the gyration of rotor between fan housing, petticoat pipe, and the heat that heat accumulation plate receives at high temperature cigarette side draught is delivered to the air of low temperature side thus realizes heat exchange.The defects such as they all also exist ash cutting, blocking, cold end corrosion in actual use, and hot air leak rate of air curtain is high.
Exploring a kind of new gas heat-exchange device, is technical task urgently to be resolved hurrily at present.
Summary of the invention
The object of the invention is improved existing air preheater, develops a kind of gyration formula gas heat exchange system, can avoid many defects of existing tubular air preheater or the above-mentioned existence of rotary regenerative air preheater.
The technical scheme that the invention is taked is a kind of gyration formula gas heat exchange system of design, its structure comprises: heat accumulation plate, transmission mechanism, wherein transmission mechanism adopt two main by turning cylinder between the transmission guipure of gyration is set, heat accumulation plate adopts heat accumulation plate row vertically, parallel, dense arrangement is on the transmission guipure of gyration, form gyration heat accumulation plate row, the flue that gyration heat accumulation plate row is arranged on high-temperature flue gas is intersegmental, cigarette section is entered at flue, the heat accumulation plate of smoke section and gyration is arranged two outer ends and is arranged end enclosure respectively, in two turning cylinder inner ends and end enclosure, internal partition is set respectively, flue enter cigarette section, the smoke section of flue, the circular passage of gyration heat accumulation plate row is formed between two secondary end enclosure and internal partition, the middle heat exchange area that circular passage is divided into gyration heat accumulation plate row middle part heat accumulation plate to communicate with flue by heat accumulation plate, the heat accumulation plate at two ends respectively with end enclosure, heat exchange zone is closed in left side between internal partition, heat exchange zone is closed on right side, both ends shell closes heat exchange zone with left side respectively, right side is closed heat exchange zone and is communicated with relative set Cryogenic air inlet pipeline and intensification air discharge duct road.
The heat accumulation plate of described heat accumulation plate row is tortuous.
Described transmission guipure also can be chain band, crawler belt etc.
The invention adopts technique scheme and this gyration formula gas heat exchange system designed by measure, during use, the high-temperature flue gas being arranged on boiler flue is intersegmental, high-temperature flue gas enters cigarette section from flue and enters middle heat exchange area, high-temperature flue gas transfers heat to corresponding levels heat accumulation plate, and the flue gas after cooling is discharged from flue smoke section, Cryogenic air enters left side from inlet pipeline respectively and closes heat exchange zone, heat exchange zone is closed on right side, the heat storing receipts in middle heat exchange area discharges to entering a left side by the heat accumulation plate of gyration respectively, the Cryogenic air in heat exchange zone is closed in right both sides, Cryogenic air is discharged from discharge line after heating up, after the heat exchange of levels heat accumulation plate again gyration to the accumulation of heat of middle heat exchange area, so recycle the high-temperature flue gas waste heat of air flue emission, continuously to Cryogenic air in addition releasing heat, accumulation of heat, this gyration formula gas heat exchange system compared with prior art, there is the ash cutting effectively avoiding tubular air preheater or rotary regenerative air preheater to exist, blocking, cold end corrosion, hot high defect of leaking out, also there is volume simultaneously little, arrangement convenience, gyration speed is adjustable, the remarkable advantages such as gas converting heat effect raising.
