Split-type pulse dust collector for drying and burning sludge

Abstract

The invention relates to a split-type pulse dust collector for drying and burning sludge, which comprises an upper box body, a lower box body and a control system, wherein the upper box body comprises at least one filtering unit; the filtering unit comprises a purified gas chamber arranged in the upper layer, a filtering chamber arranged in the lower layer and a porous plate spacer arranged at the middle; a bypass channel is arranged inside the upper box body; the bypass channel extends out of the upper box body and is communicated with the external air through a by-pass valve; the by-pass valve plays the role of protecting against high temperature; the lower box body comprises an ash bu0063ket and a material bin; a vibrating and beating device is arranged inside the ash bucket; and the control system comprises a power control box and a power supply inlet. With the structure, the invention has the characteristics that: the split-type pulse dust collector for drying and burning sludge is convenient for installation, removes the ash completely, improves the seal performance, reduces the oxygen content, prolongs the service life of the filter bags, achieves the reasonable distribution of the filter bags, avoids the problem of bridging deposition of ashes inside the ash bucket during the use, and allows the by-pass valve and the lifting valve to be closed tightly. Besides, the split-type pulse dust collector for drying and burning sludge has the high temperature protection function.

Description

technical field [0001] The invention belongs to the technical field of dust removal filters, in particular to a pulse dust collector related to sludge drying and sub-boxing in petrochemical enterprises. Background technique [0002] At present, many petrochemical enterprises have very limited space for sludge storage, and the sludge storage yard has no anti-seepage and exudate recovery facilities, which cannot meet the requirements of relevant environmental protection regulations, and the storage of sludge can only be used as a temporary measure. After the deadline, the sludge still needs to be harmlessly treated. [0003] We have invented the technology of drying and burning sludge by using the waste heat of boiler flue gas. This dust collector is used as the dust recovery of the flue gas outlet of the dryer. In the existing dust collector technology, there are many types of dust collectors, but they are not suitable for various chemical components of flue gas after slud...

AI Technical Summary

Problems solved by technology

In the existing dust collector technology, there are many types of dust collectors, but they are not suitable for various chemical components of flue gas after sludge drying in petrochemical enterprises. Due to their structural reasons, they still have the following defects, such as difficult installation and incomplete dust removal , the seal is not tight, the oxygen content is high, the service life of the filter bag is short, the arrangement distance of the filter bag is unreasonable, the length of the electromagnetic pulse valve and the filter bag is unreasonable, the ash in the ash hopper in use has bridging phenomenon, the bypass valve, The poppet valve is not closed tightly, the amount of maintenance is large, and there is no high temperature protection function, etc.
