Continuous feeding vent device for cracking furnace

Abstract

The invention discloses a continuous feeding vent device for a cracking furnace. The vent device comprises a base, wherein a spiral conveyor shell is installed on the base and extends into a cracking furnace body; a gas guide cylinder penetrating through the spiral conveyor shell and extending into the cracking furnace body is arranged on an axis of the spiral conveyor shell; a feeding auger is fixed on the peripheral surface of the gas guide cylinder; a gas collection tank is installed at the outer end of the gas guide cylinder; a gas guide cylinder rotation driving device is arranged on the gas guide cylinder; a gas guide cylinder deashing auger is installed in the gas guide cylinder; a deashing driving device is installed on the base. The vent device has the beneficial effects that the sectional area of the feeding channel is large, the feeding efficiency is high and the sealability is good; the gas guide cylinder of a vent channel is provided with the deashing auger, thus ensuring smooth venting and avoiding safety accidents caused by blockage; the gas guide cylinder also serves as the auger shaft of the feeding auger, so that the structure of the vent device is compact and the work efficiency is greatly improved.

Description

technical field [0001] The invention relates to a cracking reaction device, in particular to a feed and gas outlet device of the cracking reaction device. Background technique [0002] Most of the cracking devices in the prior art use a cracking kettle, and its disadvantages are: continuous production is not possible, heating and cracking after filling is completed, cooling the cracking kettle after the cracking is completed, removing coke residue, and then refilling, and the cracking kettle is repeatedly cooled-heated-reloaded. The cooling-reheating working process wastes a lot of energy, the cost of cracking is high, and the cracking efficiency is low. [0003] In order to solve the above technical problems, the inventor filed a patent application with the patent application number "201310016317.X" and the patent name "Plastic Recycling Continuous Gasification Cracking Multi-effect Furnace", which completely solved the technical problems existing in the prior art. The dis...

[0002] Most of the cracking devices in the prior art use a cracking kettle, and its disadvantages are: continuous production is not possible, heating and cracking after filling is completed, cooling the cracking kettle after the cracking is completed, removing coke residue, and then refilling, and the cracking kettle is repeatedly cooled-heated-reloaded. The cooling-reheating working process wastes a lot of energy, the cost of cracking is high, and the cracking efficiency is low

The disadvantage of the feed and gas outlet device of this patent application is that the diameter of the feed channel is small, the feed efficiency is low, and the gas outlet channel is easily blocked by condensed oil and gas, which requires frequent shutdown and cleaning, which greatly reduces the cracking production efficiency.
