Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, 2, and 3, the ash bucket heating device for an electric dust collector in this embodiment includes a dust removing housing 1, where one end of the dust removing housing 1 is a flue gas inlet, and the other end is a flue gas outlet. Be equipped with heat exchange coil 6 in the dust removal casing 1, heat exchange coil 6 locates the export loudspeaker end of dust removal casing 1, and heat exchange coil 6 locates export loudspeaker roof 4 below, and both suspend heat exchange coil 6 in midair in dust removal casing 1 through jib 5 and two nut fixed connection in making. One end of the heat exchange coil 6 is an air inlet, the other end of the heat exchange coil is an air outlet, and the air outlet and the air inlet are arranged oppositely. The bottom of the dust removal shell 1 is provided with a plurality of ash buckets 2 which are arranged at intervals, the ash buckets 2 are communicated with the dust removal shell 1, an ash bucket heating coil 3 is arranged in the ash buckets 2, and the ash bucket heating coil 3 is attached to the inner wall of the ash bucket 2. The inlets of the plurality of ash bucket heating coils 3 are connected through a connecting pipeline, the inlet of the connecting pipeline is connected with an air outlet, and a fan is arranged on the connecting pipeline. High-temperature flue gas enters the dust removal shell through the flue gas inlet, cold air enters the heat exchange coil through the air inlet, and the high-temperature flue gas exchanges heat with the cold air in the heat exchange coil to reduce the temperature of the high-temperature flue gas and raise the temperature of the cold air so as to form low-temperature flue gas and hot air; the low temperature flue gas flows out through the exhanst gas outlet, and hot-air flows out through the air outlet and flows into the connecting pipeline, and the fan blows hot-air in the connecting pipeline to each ash bucket heating coil, so that heat in the ash bucket heating coil is transferred to the inner wall of the ash bucket, and the purpose of heating the ash bucket wall plate is achieved.
The cold air in the heat exchange coil is heated by the smoke temperature in the dust removal shell, and the hot air in the connecting pipeline is conveyed to the ash bucket heating coil by the fan, so that the ash bucket wall plate is heated. The method reduces the working procedures of the main pipeline, the matched valve, heat preservation and the like, reduces the problem of heat efficiency loss in the long pipeline conveying process, simultaneously reduces the informing procedures before installation, and can more quickly and quickly advance the engineering installation progress; meanwhile, the problems of the discharge of condensed water after steam heating of the traditional ash bucket, related processes and the like are not considered. This application structural layout is reasonable, has improved the thermal efficiency utilization ratio, and labour saving and time saving has reduced the project cost.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
