A device for producing fuel oil and gas by pyrolysis of waste toner cartridge toner

Abstract

The invention discloses a device for producing fuel oil and gas by pyrolysis of waste toner cartridge carbon powder. The device comprises a pyrolysis reactor 1, a solid residue storage tank 2, a powder pump 3, a valve 4, a condenser 5, an oil storage tank 6, a vacuum pump 7, and a non-condensable gas collecting bottle 8, wherein the storage tank 2 is connected with the lower part of an end part of the pyrolysis reactor 1, and the powder pump 3 is arranged on a pipeline between the storage tank 2 and the pyrolysis reactor 1; the upper part of the end part of the pyrolysis reactor 1 is connected with the condenser 5 by virtue of an oil-gas delivery pipe, and the valve 4 is arranged on the oil-gas delivery pipe between the pyrolysis reactor 1 and the condenser 5; and the oil storage tank 6 is connected to the bottom of the condenser 5, the gas collecting bottle 8 is connected with the condenser 5 by virtue of an oil-gas delivery pipe, and the vacuum pump 7 is arranged on the oil-gas delivery pipe between the gas collecting bottle 8 and the condenser 5. The processes of pyrolysis, condensation and collection of the device are performed synchronously to realize separate collection of pyrolysis oil, pyrolysis gas and solid residues, and the obtained fuel oil and gas are high in quality, so that the device has significant economic and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of solid waste recycling. More specifically, it relates to a device for recycling waste toner cartridge toner, that is, a device for producing fuel oil and gas by pyrolyzing waste toner cartridge toner. Background technique [0002] With the accelerated development of electronic information, printers, copiers and fax machines are constantly updated. Toner cartridges are the most frequently replaced consumables, and the number of discarded toner cartridges reaches 75 million per year. The residual amount of toner in a used toner cartridge can reach 7.8%, so there is a large amount of residual toner to be disposed of. Carbon powder is a powder with a particle size of 5-12 µm, and its main components are polyacrylate-styrene, polyethylene / polypropylene paraffin, hydroxyaromatic acid derivatives, ferroferric oxide, silicon dioxide, etc. Among them, polyacrylate-styrene, polyethylene / polypropylene paraffin, and...

AI Technical Summary

Problems solved by technology

This method selectively recycles residual toner, and low-quality residual toner cannot be used because it does not meet the usage standards; the quality of recovered industrial toner varies, and the recycling capacity of waste toner treatment methods for specific brands is limited

In addition, the following invention patents all mention waste toner cartridge toner, but focus on the recycling and collection of waste toner cartridge toner. Problem: Patent "A New Type of Toner Cartridge Recovery Machine" (Yang Jinxu et al., CN204576061U); Patent "Waste Toner Recovery Device" (Li Qionglian, CN201780459U); , CN103488070A); Patent "Toner Cartridge Residual Powder Recovery Machine" (Wu Haifeng, CN202948251U)

At present, there are few patent applications and related literature reports on waste toner cartridge recycling technology, and there is no report on treating toner in waste toner cartridges through efficient pyrolysis technology
