Description

Technical Field

[0001] This utility model relates to the field of printing press exhaust gas treatment technology, specifically a printing press exhaust gas collection and treatment device. Background Technology

[0002] Printing press exhaust gas collection and treatment equipment is an important device specifically designed for collecting and treating exhaust gases generated by printing presses. This equipment typically consists of multiple components that work together to collect and treat the exhaust gases. The working principle of printing press exhaust gas collection and treatment equipment is relatively complex, but can generally be divided into the following steps: Exhaust gas collection: Through the action of the suction pipe and the air pump, the exhaust gas generated by the printing press is collected from the source. Exhaust gas transmission: The collected exhaust gas is transmitted through the guide pipe to the treatment chamber, preparing for the subsequent treatment steps. Exhaust gas treatment: In the treatment chamber, the exhaust gas undergoes a series of treatment processes, such as adsorption, catalytic combustion, and photolysis, to remove harmful substances. Purified emission: After the treated exhaust gas meets emission standards, it is safely discharged into the atmosphere through the emission pipeline.

[0003] However, it still has some drawbacks. For example, when traditional printing press exhaust gas collection and treatment equipment uses activated carbon for adsorption, the lack of a convenient method for replacing the activated carbon can easily lead to long-term use of the activated carbon affecting its adsorption performance. It may also cause secondary pollution due to failure to replace the activated carbon in time. In addition, when traditional printing press exhaust gas collection and treatment equipment uses high temperature to treat exhaust gas, it usually allows volatile organic compounds to be completely burned under high temperature and sufficient air conditions, decomposing them into CO2 and H2O, which are eventually discharged into the atmosphere. However, the purchase cost is generally relatively high.

[0004] To address the aforementioned problems, this application proposes a printing press exhaust gas collection and treatment device. Summary of the Invention

[0005] The purpose of this utility model is to provide a printing press exhaust gas collection and treatment device to solve the problems mentioned in the background art. In the prior art, the lack of a convenient method for replacing activated carbon makes it easy for long-term use of activated carbon to affect its adsorption performance. It may also lead to secondary pollution due to failure to replace activated carbon in time. Furthermore, when using high temperature to treat exhaust gas, volatile organic compounds are usually completely burned under high temperature and sufficient air conditions to decompose into CO2 and H2O and finally discharged into the atmosphere, but the purchase cost is generally high.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a printing press exhaust gas collection and treatment device, comprising a housing, a first gas pipe fixedly connected to one outer surface of the housing, a purifier fixedly connected to one outer surface of the first gas pipe, an air inlet pipe fixedly connected to one outer surface of the purifier, a catalytic tower fixedly connected to the upper outer surface of the purifier, an adsorption component movably connected to the front outer surface of the housing, an adsorption groove formed on the front outer surface of the housing, a second gas pipe fixedly connected to one outer surface of the housing, a secondary purifier fixedly connected to one outer surface of the second gas pipe, a third gas pipe fixedly connected to one outer surface of the secondary purifier, and a heating component fixedly connected to the lower outer surface of the third gas pipe.

[0009] Preferably, a rotating shaft is fixedly connected to the upper outer surface of the second adsorption frame, and nuts are rotatably connected to the four outer surfaces of the rotating shaft. A connecting block is fixedly connected to the lower outer surface of the first adsorption frame, and a rotating shaft is movably connected to one outer surface of the connecting block. A connecting block is movably connected to one outer surface of the rotating shaft.

[0010] Preferably, the heating assembly includes a gas collecting pipe, a high-temperature lamp, a threaded tube, a heating base, and a gas outlet pipe, with the lower outer surface of the third gas pipe fixedly connected to the gas collecting pipe.

[0011] Preferably, a threaded spiral tube is fixedly connected to the lower outer surface of the gas collecting pipe, a high-temperature lamp tube is fixedly connected to the inner surface of the threaded spiral tube, a heating base is fixedly connected to the lower outer surface of the high-temperature lamp tube, and a gas outlet pipe is fixedly connected to one side outer surface of the heating component.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes an adsorption assembly consisting of an adsorption frame 1, an activated carbon mesh, an adsorption frame 2, a slot, a threaded groove, a threaded button, a rotating shaft 1, and a nut, which work together to allow the activated carbon in the device to be replaced after long-term use without disassembling the device. By rotating the threaded button, the button is disengaged from the nut, and the nut can then rotate around the rotating shaft 1 to disengage from the slot. At this point, the adsorption frame 1 and the adsorption frame 2 can be opened, allowing the activated carbon mesh to be easily replaced.

[0014] This invention utilizes a heating assembly with a gas collecting pipe, a high-temperature lamp, a threaded tube, a heating base, and a gas outlet pipe working together. Waste gas enters the threaded tube from the gas collecting pipe, where the high-temperature lamp begins heating. The waste gas then moves in a spiral motion around the high-temperature lamp within the threaded tube, allowing for sufficient high-temperature purification. The heating base at the bottom further purifies the waste gas before it is finally discharged through the outlet pipe. This heating assembly reduces the cost of purchasing the device, and the use of a high-temperature lamp enhances safety by eliminating the risk of open flames and other safety hazards, thus promising a brighter future.

An adsorption frame 12 is movably connected to the outer surface of the front end of the housing 1. An activated carbon mesh 13 is movably connected to one side of the outer surface of the adsorption frame 12. An adsorption frame 2 14 is movably connected to one side of the outer surface of the activated carbon mesh 13. A slot 15 is fixedly connected to the upper outer surface of the adsorption frame 12. A threaded groove 16 is opened on the upper outer surface of the slot 15. A threaded button 17 is threadedly connected to the inner surface of the threaded groove 16. Through the mutual cooperation of the adsorption frame 12, activated carbon mesh 13, adsorption frame 2 14, slot 15, threaded groove 16, threaded button 17, rotating shaft 18, and nut 19 in the adsorption assembly 6, when the activated carbon in the device needs to be replaced after long-term use, there is no need to disassemble the device. By rotating the threaded button 17, the threaded button 17 is disengaged from the nut 19. At this time, the nut 19 can rotate around the rotating shaft 18 and disengage from the slot 15. At this time, the adsorption frame 12 and the adsorption frame 2 14 can be opened, so that the activated carbon mesh 13 can be easily replaced.

[0022] In this embodiment, as Figure 3 As shown, a rotating shaft 18 is fixedly connected to the upper outer surface of the adsorption frame 14, and nuts 19 are rotatably connected to the four outer surfaces of the rotating shaft 18. A connecting block 20 is fixedly connected to the lower outer surface of the adsorption frame 12, and a rotating shaft 21 is movably connected to one outer surface of the connecting block 20. A connecting block 22 is movably connected to one outer surface of the rotating shaft 21.

[0023] In this embodiment, as Figure 4As shown, the heating assembly 11 includes a gas collecting pipe 23, a high-temperature lamp 24, a threaded spiral tube 25, a heating base 26, and a gas outlet pipe 27. The lower outer surface of the third gas pipe 10 is fixedly connected to the gas collecting pipe 23. The lower outer surface of the gas collecting pipe 23 is fixedly connected to the threaded spiral tube 25. The inner surface of the threaded spiral tube 25 is fixedly connected to the high-temperature lamp 24. The lower outer surface of the high-temperature lamp 24 is fixedly connected to the heating base 26. A gas outlet pipe 27 is fixedly connected to one outer surface of the heating assembly 11. The heating assembly 11 is connected to the gas collecting pipe 23, the high-temperature lamp 24, and the threaded spiral tube 25. The heating base 26 and the exhaust pipe 27 work together to allow the exhaust gas to enter the spiral tube 25 from the gas collection pipe 23. The high-temperature lamp 24 then starts to heat the exhaust gas. The exhaust gas moves around the high-temperature lamp 24 in the spiral tube 25, allowing the high-temperature lamp 24 to perform sufficient high-temperature purification of the exhaust gas. The heating base 26 at the bottom further purifies the exhaust gas, and finally the exhaust gas is discharged from the exhaust pipe 27. The heating component 11 saves on the purchase cost of the device, and the use of the high-temperature lamp 24 makes the device safer, eliminating the safety hazards such as open flames, thus bringing about a better prospect for use.

[0024] Working Principle: First, the exhaust gas enters the purifier 3 through the inlet pipe 4 for initial purification. Then, the exhaust gas enters the housing 1 through the first air pipe 2, where the activated carbon mesh 13 in the adsorption component 6 absorbs the organic matter. Next, the exhaust gas enters the secondary purifier 9 through the second air pipe 8 for secondary purification. After purification, it enters the heating component 11 through the third air pipe 10 for heating. The exhaust gas then enters the threaded swirl tube 25 through the collecting pipe 23. Through the coordinated operation of the collecting pipe 23, high-temperature lamp 24, threaded swirl tube 25, heating base 26, and outlet pipe 27 in the heating component 11, the exhaust gas enters the threaded swirl tube 25 from the collecting pipe 23. The high-temperature lamp 24 then begins heating, and the exhaust gas swirls around the threaded swirl tube 25. The high-temperature lamp 24 moves in a spiral motion, allowing it to thoroughly purify the exhaust gas at high temperatures. The heating base 26 at the bottom further purifies the exhaust gas, ultimately allowing it to be discharged through the exhaust pipe 27. The heating component 11 saves on the purchase cost of the device, and the use of the high-temperature lamp 24 makes the device safer, eliminating safety hazards such as open flames, thus leading to better application prospects. When the activated carbon mesh 13 needs to be replaced, there is no need to disassemble the device. Simply rotate the threaded button 17 to disengage it from the nut 19. At this time, the nut 19 can rotate around the first pivot 18 and disengage from the slot 15. Then, the first adsorption frame 12 and the second adsorption frame 14 can be opened, allowing the activated carbon mesh 13 to be easily replaced.
