Abstract

The invention belongs to the technical field of waste plastic treatment equipment, and particularly relates to an anaerobic feeding system for a pyrolyzing furnace, which comprises a feeding and conveying device, a stock bin and a discharging and guiding device, the upper end of the stock bin is provided with a feeding hole connected with the feeding and conveying device, and the lower end of the stock bin is provided with a discharging hole connected with the pyrolyzing furnace; the discharging and guiding device is used for guiding materials in the stock bin into the pyrolyzing furnace, a nitrogen inlet and an exhaust port are formed in the stock bin, an oxygen content detector is arranged in the stock bin, the nitrogen inlet is in an open or closed state based on a detection signal of the oxygen content detector, and when the oxygen content is larger than a set value, the nitrogen inlet is opened, nitrogen enters the stock bin from the nitrogen inlet to replace air in the stock bin, and the air is exhausted from the exhaust port, so that an oxygen-free environment in the stock bin is ensured, and toxic gas dioxin generated due to the fact that oxygen-containing air is brought in when a feeding system supplies materials to the pyrolyzing furnace is avoided; and meanwhile, the potential safety hazard of burning explosion possibly caused by contact of air and high-temperature oil gas in the pyrolyzing furnace is eliminated.

Description

technical field [0001] The invention belongs to the technical field of waste plastic treatment equipment, and in particular relates to an oxygen-free feeding system for a pyrolysis furnace. Background technique [0002] Waste plastics are widely used in modern people's daily life and industrial, agricultural and commercial activities, but they have also become a pollution source that seriously affects the ecological environment. The environmental protection disposal and recycling of waste plastics has become an important part of "environmental protection", while a large number of non-sortable, non-toxic Low-value waste plastics with recycling value cannot be incinerated or landfilled; however, thermal cracking method can be used for voluntary treatment, which can generate liquid fuel oil, carbon residue and combustible gas, which not only regenerates waste resources, but also makes full use of them. , and does not produce three wastes, protecting the environment.
