A uniform air dust removal device and sludge drying equipment for sludge drying equipment

Abstract

This application relates to a uniform air dust removal device and sludge drying equipment for sludge drying equipment. The uniform air dust removal device includes an oven, an external circulation fan, a heat exchange skid and a dust removal system; the oven, The outer circulation fan and the heat exchange skid are connected to form an outer circulation air passage; the oven is provided with a transmission mesh belt and an inner circulation air passage; the upper end of the inner circulation air passage is provided with a plurality of deflectors, and A plurality of deflectors are used to guide the internal circulating air in the internal circulating air channel to the transmission mesh belt; an air uniform plate is arranged between the deflectors and the transmission mesh belt; the oven and the The heat exchange skids are connected through an external circulating air return channel, and a dust removal system is provided at both ends of the external circulating air return channel. In this application, through the deflector and the air equalizing plate, the internal circulating air can be evenly and fully contacted and exchanged with the sludge at various positions on the transmission mesh belt, so as to improve the drying efficiency.

Description

A kind of uniform air dust removal device for sludge drying equipment and sludge drying equipment technical field The application relates to the field of sludge drying, in particular to a kind of air-equalizing dedusting device and sewage sludge drying equipment for sludge drying. Mud drying equipment. Background technique The internal fluid (hot air) of the traditional small electric heat pump type oven is unevenly distributed, which causes the entire mesh belt to transmit the sludge. The hot air passes through unevenly, some places have more hot air, and some places have less hot air, which leads to the pollution of each position of the mesh belt. The mud cannot fully contact with the hot air for heat exchange, so that there is a blind area for the evaporation and dehydration of the sludge in the oven. At the same time, due to the circulation of hot air To cause more dust. In terms of dust removal, plate and belt dust collectors are usually used, which have poor ...

AI Technical Summary

Problems solved by technology

[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 the hot air for heat exchange, so that 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 and belt dust collectors are usually used, 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 in the traditional small electric heat pump oven, no effective solution has been given in the prior art
