Ash residue discharging device for acrylic cracking furnace

Abstract

The invention discloses an residue ash discharging device for an acrylic cracking furnace. The device comprises a main cylindrical shell which extends to the left and right, a gas residue inlet is arranged at the upper part of the right end of the main cylindrical shell, a spiral feeder is arranged in the main cylindrical shell, a tapered ash residue outlet is arranged at the lower part of the wall of the main cylindrical shell, the ash residue outlet is provided with a curved surface sealing cover which is matched with the ash residue outlet and can be opened and closed, the curved surface sealing cover is connected with a driving mechanism, and an ash residue receiving bucket is arranged below the ash residue outlet. The device can be started at about 180 DEG C to carry out ash residue discharging work, and the temperature of a furnace body still keeps a high temperature after the ash residue removal is completed, so the afresh heating energy is greatly saved, the working efficiencyis improved, and the production cost is saved; and the device saves a lot of manpower and material resources and facilitates the centralized processing of ash residues especially when 8-15 cracking furnaces run simultaneously.

Description

technical field [0001] The invention relates to the technical field of ash and slag discharge devices, in particular to an ash and slag discharge device for an acrylic cracking furnace. Background technique [0002] When the chemical industry cracks organic matter, some substances and impurities that cannot be completely cracked in the cracking furnace will be carbonized to form ash under the action of high temperature, which must be cleaned regularly to ensure the normal operation of the equipment. With the advancement of technology, the cracking furnaces in the chemical cracking industry are basically in the form of converters. On the central axis of both ends of the converter, movable and sealed through-pipes are arranged as the feed, gas and ash discharge devices. However, for each cracking furnace that works continuously, it usually takes about two days to clean up the ash and slag. The work is frequent and labor-intensive, and it is difficult to guarantee cleanliness....

AI Technical Summary

Problems solved by technology

Because of the structure, the intersecting part of the two cylinders forms a dead angle. During the production process, the ash has been deposited at the interface, and the screw device cannot scrape and remove the ash. When the temperature cools to normal temperature, the ash freezes into a hard structure. Blocks, sometimes even the cover and the tee joint are glued together, which can only be slowly chiseled with a chisel, which is very time-consuming and laborious to remove
