Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a split-type burner waste acid pyrolysis furnace, including a combustion chamber 1, a feed pipe 2 fixedly provided on the left side of the combustion chamber 1, and two sets of burners 3 fixedly provided on the upper part of the combustion chamber 1. The lower part of the combustion chamber 1 is connected to a first pyrolysis chamber 4 through a partition, and the lower part of the first pyrolysis chamber 4 is connected to a second pyrolysis chamber 5 through a partition. The first pyrolysis chamber 4 is provided with first air inlet pipes 6 on both sides. The combustion chamber 1 is fixedly provided with a connecting pipe 7 on the back, and a fan 9 is provided inside the connecting pipe 7. The other end of the connecting pipe 7 is connected to a concave air inlet pipe 8, and the other end of the concave air inlet pipe 8 is connected to a spray arm 10 inside the first pyrolysis chamber 4 and the second pyrolysis chamber 5, respectively. Multiple sets of nozzles 11 are evenly provided on the spray arm 10.

[0019] Furthermore, the combustion chamber 1 forms a suction structure with the connecting pipe 7 under the drive of the fan 9, and the connecting pipe 7 forms a communication structure with the first pyrolysis chamber 4 and the second pyrolysis chamber 5 through the concave air intake pipe 8, the spray arm 10, and the nozzle 11, respectively, so that the high temperature in the combustion chamber 1 can be simultaneously introduced into the two sets of pyrolysis chambers, thereby ensuring that the two sets of pyrolysis chambers can carry out pyrolysis work normally.

[0020] Multiple sets of through holes 12 are evenly provided on the partition between the first pyrolysis chamber 4 and the second pyrolysis chamber 5, and a baffle 13 is placed below the through holes 12. Multiple sets of support plates 14 are evenly provided inside the second pyrolysis chamber 5 below the baffle 13.

[0021] Furthermore, the first pyrolysis chamber 4 is connected to the second pyrolysis chamber 5 through the through hole 12 on the partition, so that the waste acid in the first pyrolysis chamber 4 is processed and then processed again in the second pyrolysis chamber 5, thereby ensuring the pyrolysis effect of the waste acid.

[0022] Electric push rods 15 are respectively provided on the outer walls of both sides of the second pyrolysis chamber 5 below the support plate 14, and telescopic arms 16 are provided on the electric push rods 15. A connecting plate 17 is provided at the other end of the telescopic arm 16, and a connecting rod 18 is fixedly provided on the upper side of the connecting plate 17. The other end of the connecting rod 18 is connected to the baffle 13. The second pyrolysis chamber 5 has openings on the outer walls of both sides, and the baffle 13 moves within the openings. An exhaust pipe 19 is fixedly provided on the front of the second pyrolysis chamber 5.

[0023] Furthermore, the baffle 13 forms a supporting structure with the second pyrolysis chamber 5 through the support plate 14, and the baffle 13 forms a bidirectional horizontal pushing structure with the second pyrolysis chamber 5 through the telescopic arm 16, the connecting plate 17, and the connecting rod 18 under the action of the electric push rod 15. Thus, the baffle 13 ensures that the two sets of pyrolysis chambers can carry out pyrolysis work independently, thereby avoiding the waste acid flowing in the two sets of pyrolysis chambers and affecting its pyrolysis effect.

[0024] Working Principle: In the split-type burner waste acid pyrolysis furnace, fuel is first fed into combustion chamber 1 through feed pipe 2 and burned through burner 3, generating high temperature in combustion chamber 1. Simultaneously, waste acid is fed into first pyrolysis chamber 4 through first air inlet pipe 6. Then, blower 9 is activated, and the high temperature in combustion chamber 1 enters connecting pipe 7 under the action of blower 9, and then evenly enters spray arm 10 through concave air inlet pipe 8. This, in turn, is evenly distributed into first pyrolysis chamber 4 and second pyrolysis chamber 5 through multiple sets of nozzles 11, ensuring normal operation of both pyrolysis chambers. After the waste acid in first pyrolysis chamber 4 has been processed for a certain time, the electric pusher on the outer wall of second pyrolysis chamber 5 can be activated. The electric push rod 15 drives the connecting plate 17 outward through the telescopic arm 16, thereby moving the baffle 13 to the outside of the second pyrolysis chamber 5 via the connecting rod 18. This allows the waste acid processed in the first pyrolysis chamber 4 to enter the second pyrolysis chamber 5 through the through hole 12 for secondary processing, thus ensuring the pyrolysis efficiency of the waste acid. During the operation of the second pyrolysis chamber 5, the electric push rod 15 can be used to return the baffle 13 to its original position, thereby allowing waste acid to be introduced into the first pyrolysis chamber 4 again, ensuring that the two pyrolysis chambers can work synchronously. The waste acid processed in the second pyrolysis chamber 5 is discharged outward through the exhaust pipe 19. This is the operation process of the split-type flame-type waste acid pyrolysis furnace.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
