[0053] The method for deep treatment of API waste gas provided in this embodiment adopts the above-mentioned API waste gas deep treatment device, and comprises the following steps:

[0054] Step 1: The waste gas enters the dust filter bin from the inlet for preliminary filtration, passes through the air inlet 3 43 and filters the dust particles in the waste gas by rotating the dust filter plate 42; then passes through the air outlet 3 41 and enters the reaction liquid bin.

[0055] Step 2: The waste gas after the initial filtration reacts with the reaction filler in the reaction liquid chamber and continues to enter the combustion chamber 25 through the second air inlet 26;

[0056] The waste gas after the initial filtration enters the reaction liquid tank 37 through the through pipe 36, and the water pump 35 draws the reaction liquid in the reaction liquid tank 37 into the transfer box 38, and then enters the spray rod 31 through the hollow shaft 32.

[0063] The waste gas after the initial filtration enters the reaction liquid bin 37 through the through pipe 36, and the water pump 35 draws the reaction liquid in the reaction liquid bin 37 into the transfer box 38, and then enters the spray rod 31 through the hollow shaft 32. The motor 56 drives the gear 1 55 to rotate, thereby acting on the gear 2 54 on the surface of the hollow shaft 32, driving the spray rod 31 to rotate and spray on the reaction filler 33, and the waste gas passes through the reaction filler 33 for reaction; at the same time, the hollow shaft 32 drives the rotating dust filter plate 42 to rotate, and the bevel gear 2 52 on the surface of the hollow shaft 32 drives the bevel gear 1 51 to rotate, thereby driving the brush 57 to rotate, and the surface of the rotating dust filter plate 42 is cleaned to avoid excessive clogging of dust particles resulting in a reduction in air intake. The cleaned dust is collected through the funnel 58 and enters the dust collecting box 59.

[0064] The exhaust gas can be discharged after the initial reaction, or continue to enter the combustion chamber 25 through the air inlet 26. The heater 22 controls the heating rod 23 to heat the air to burn the exhaust gas. The exhaust gas passes through the partition plate 24 in the combustion chamber 25 to increase the residence time of the exhaust gas, so that the exhaust gas can be fully burned and decomposed.

[0065] The waste gas can be discharged after the reaction, or continue to enter the condenser for cooling, or skip the combustion chamber 25 for combustion and directly enter the photolysis chamber 13 through the air outlet 21. The waste gas enters the transparent spiral reaction tube 12 along the air inlet 15, and is decomposed and purified by the high-intensity ultraviolet light of the high-power ultraviolet lamp 11 inside the transparent spiral reaction tube 12, and is finally discharged through the air outlet 14.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.

9. The device for deep treatment of bulk drug waste gas according to claim 8, characterized in that: The gear one (55) is meshedly connected with the gear two (54); the bevel gear two (52) is meshedly connected with the bevel gear one (51).

10. A method for deep treatment of bulk drug waste gas, using the apparatus for deep treatment of bulk drug waste gas according to claims 1 to 9, characterized in that: The following steps are involved: Step 1: The waste gas enters the dust filter bin from the inlet, passes through the air inlet three (43), filters the dust particles in the waste gas by rotating the dust filter plate (42), and then passes through the air outlet three (41) into the reaction liquid bin; Step 2: After the primary filtration, the waste gas undergoes a preliminary reaction with the reaction filler in the reaction liquid chamber, and then enters the combustion chamber (25) through the second air inlet (26); Step 3: Start the heater (22) to control the heating rod (23) to heat the air to burn the waste gas in the combustion chamber (25), and use the partition plate (24) in the combustion chamber (25) to increase the combustion reaction time of the waste gas; Step 4: The waste gas after full combustion and decomposition is discharged, or continues to enter the condenser for cooling, or enters the photolysis chamber (13) through the second outlet (21); Step 5: The waste gas enters the transparent spiral reaction tube (12) in the photolysis chamber (13) through the air inlet 1 (15), and the waste gas inside the transparent spiral reaction tube (12) is irradiated and decomposed and purified by the ultraviolet light emitted by the ultraviolet lamp (11), and finally discharged through the air outlet 1 (14).
