Quick pyrolyzing furnace

Abstract

The invention discloses a quick pyrolyzing furnace, comprising a furnace body and a radiating tube heater; the radiating tube heater comprises: n radiating tubes that are arranged at intervals, each radiating tube has a first port and a second port, wherein n> / =2; two burner components each of which comprises a burner and (n-1) dividing plates, an intake passage is arranged in each burner, the (n-1) dividing plates are arranged in a corresponding intake passage in mutually separated manner, the dividing plates and the sidewall of the intake passage jointly define n mutually independent sub-passages, the intake ends of the n sub-passages jointly define a gas inlet of the gas incoming passage, first ports of the n radiating tubes are in one-to-one correspondence and communication with n sub-passages of one burner component, second ports of the n radiating tubes are in one-to-one correspondence with the n sub-passages of another burner component. The quick pyrolyzing furnace has the advantages that a radiant tube heater is more stable, and a burner-front line is simplified.

Description

technical field [0001] The invention relates to the technical field of pyrolysis, in particular to a fast pyrolysis furnace. Background technique [0002] The regenerative radiant tube heater applies the advanced high-temperature air combustion technology to the gas radiant tube. The combustion product does not contact the heated object, and the sensible heat of the combustion flue gas in the tube is used to preheat and support combustion through the setting of the regenerator. Air or gas has many characteristics such as high combustion thermal efficiency, strong heating capacity, uniform heat flow on the surface of the tube wall, stable operation, and high equipment reliability. It has been widely used in various heat treatment furnaces. [0003] The regenerative radiant tube heater of the fast pyrolysis furnace in the related art generally has a radiant tube, two regenerative burners, two small burners, two reversing valves, two regulating valves and other connecting struc...

AI Technical Summary

Problems solved by technology

When multiple regenerative radiant tube heaters are applied to the fast pyrolysis furnace, because each set of regenerative radiant tube heaters has too many supporting accessories, it occupies a large space, has many operating points, and many fault points. The pipeline is complex, which brings a lot of inconvenience to maintenance and operation, and due to the limitation of the volume of the burner, the net distance between the radiant tubes of two adjacent regenerative radiant tube heaters is relatively large
