Air uniformizing and dust removing device for sludge drying equipment and sludge drying equipment

Abstract

The invention relates to an air uniformizing and dust removing device for sludge drying equipment and the sludge drying equipment. The air uniformizing and dust removing device comprises a drying oven, an outer circulating air fan, a heat exchange skid and a dust removing system, wherein the drying oven, the outer circulating air fan and a heat exchange skid are communicated to form an outer circulating air channel; the drying oven is provided with a transmission mesh belt and an inner circulating air channel; a plurality of flow guide plates are arranged at the upper end of the inner circulating air channel and are used for guiding inner circulating air in the inner circulating air channel to the conveying mesh belt; an air uniformizing plate is arranged between the flow guide plates and the transmission mesh belt; and the drying oven and the heat exchange skid are connected through an outer circulating air return channel, and dust removal systems are arranged at the two ends of the outer circulating air return channel. Through the flow guide plates and the air uniformizing plate, inner circulating air can be in uniform and full contact with sludge at all positions on the conveying mesh belt for heat exchange, and the drying efficiency is improved.

Description

technical field [0001] The present application relates to the field of sludge drying, in particular to an air uniform dust removal device and sludge drying equipment for sludge drying equipment. Background technique [0002] The uneven distribution of the fluid (hot air) inside the oven of the traditional small electric heat pump model leads to uneven passage of the hot air in the mesh belt for transporting sludge. The sludge in each position cannot fully contact with the hot air for heat exchange, so there is a blind area for sludge evaporation and dehydration in the oven. At the same time, due to the circulation direction of the hot air, the dust is relatively large. In terms of dust removal, plate-type and belt-type dust collectors are usually used, and the dust removal effect is poor, and the dust removal device needs to be replaced manually on a regular basis, which is labor-intensive. [0003] Based on the above-mentioned defects existing in the traditional small ele...
