Detailed description of the invention
Fig. 1 is overall structure of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of technical solution：A kind of catalysis oxidation heat recovery apparatus of temperature self adjusting,
Including main air blower 2, heat recovering heat exchanger 4, heater 6, Catalytic oxidation furnace 8 and air quantity adjusting air valve 13, described 2 one end of main air blower
For exhaust gas inlet 1, the other end is connected to heat recovering heat exchanger 4 by first pipe 3, and the heat recovering heat exchanger 4 passes through the second pipe
Road 5 is connected to heater 6, and the heater 6 is connected to Catalytic oxidation furnace 8 by third pipeline 7, and the Catalytic oxidation furnace 8 passes through the
Four pipelines 9 are connected to heat recovering heat exchanger 4, and the heat recovering heat exchanger 4 is connected to chimney 11, first pipe by the 5th pipeline 10
Road 3 is connected to third pipeline 7 by the 6th pipeline 12, and air quantity adjusting air valve 13 is installed on the 6th pipeline 12.
In the present invention, catalyst is filled in Catalytic oxidation furnace 8, the noble metal that metallic carrier is filled in catalytic bed is urged
Agent, noble metal use Pt, Pd etc., and the mesh number of catalyst carrier is -300 mesh of 200 mesh.
In the present invention, second temperature sensor 15 is installed in Catalytic oxidation furnace 8；The third pipeline 7 is close to catalysis oxygen
Change 8 inlet of furnace and the first temperature sensor 14 is installed；Heater 6 uses electric heater, neat gas burner, liquefied petroleum gas
One of burner.
Working principle：There are two types of operating status, warming-up starting state and normal operating conditions by the present invention.Start shape in warming-up
Under state, air enters heat recovering heat exchanger after blower pressurizes and heats up, after heat up through electric heater, then be discharged into Catalytic oxidation furnace
Interior heatable catalyst, hot-air carries out heat recovery through heat recovering heat exchanger again later, is finally discharged into smoke stack emission.It is opened in warming-up
During dynamic, the temperature sensor of electric heater capacity and Catalytic oxidation furnace entrance is chain, when the air for entering Catalytic oxidation furnace
Temperature reach 250 DEG C -650 DEG C of Catalytic oxidation furnace thermotonus window after, warming-up start-up course terminates.
Under normal operating conditions, exhaust gas enters heat recovering heat exchanger after blower pressurizes and heats up, after through electric heater,
It is discharged into Catalytic oxidation furnace again, when Catalytic oxidation furnace inlet flue gas temperature is not up to 250 DEG C -650 DEG C of catalyst reaction window, electricity
