This leads to some harmful substances failing to be effectively decomposed or adsorbed due to insufficient contact with the oxidant, resulting in low purification efficiency. Therefore, we need to propose a flue gas purification device for hydrogenation furnaces. Utility Model Content

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A flue gas purification device for a hydrogenation furnace includes a purification box 1 and an extraction pump 5. A fixing plate 2 is fixedly connected to the inner wall of the purification box 1. Multiple sets of partitions 3 are fixedly connected to the top of the fixing plate 2 and the inner top of the purification box 1. A purification channel is separated between the top of the fixing plate 2 and the inner top of the purification box 1 by the multiple sets of partitions 3.

[0026] Both the inlet and outlet ends of the pump 5 are connected to a delivery pipe 6. The delivery pipe 6 at the outlet end of the pump 5 is connected to a main delivery pipe 7. Multiple sets of delivery branch pipes 8 are connected to the main delivery pipe 7, and all sets of delivery branch pipes 8 are located in the purification channel.

[0027] It should be noted that multiple sets of partitions 3 installed on the top of the fixed plate 2 have connecting ports 9. Oxidant is provided in the purification channel. The liquid level of the oxidant is higher than that of the connecting port 9, which can prevent air from flowing in the purification channel through the connecting port 9. The oxidant can flow in the purification channel through the connecting port 9. A baffle 31 is fixedly connected to the top of the fixed plate 2. When the liquid level of the oxidant collected in the purification channel is higher than that of the baffle 31, the excess oxidant can fall to the other side of the baffle 31 for storage.

[0028] The side of the purification chamber 1 is sealed with a movable door 27, which can be opened to clean the purification channel.

[0029] In an optional embodiment: such as Figure 3 As shown, the interior of the purification box 1 is divided into a first chamber and a second chamber by a fixing plate 2.

[0030] It should be noted that the side of the purification box 1 is connected to a water inlet pipe 10, through which an oxidant can be added to the second chamber.

[0031] In an optional embodiment: such as Figure 1 , 2 and Figure 4 As shown, it also includes a filter tank 14. A connecting pipe 13 connected to the purification channel is installed on one side of the purification box 1. One end of the connecting pipe 13 is connected to the bottom of the filter tank 14 and extends into the interior of the filter tank 14.

[0032] The filter tank 14 has multiple sets of replacement ports, and each set of replacement ports is equipped with an annular seat 17. The filter tank 14 is symmetrically and fixedly connected with multiple sets of first support blocks 15 and second support blocks 19 corresponding to the replacement ports. The surface of the annular seat 17 is symmetrically and fixedly connected with first fixing blocks 18 and second fixing blocks 20. The top of the first support block 15 is fixedly connected with a fixing post 16. The first fixing block 18 is movably installed in the fixing post 16. The second fixing block 20 is equipped with a fixing screw 21, which is threaded into the second support block 19.

[0033] Multiple annular seats 17 contain, in order from bottom to top, wire mesh demisters 28, fiberglass boards 29, and honeycomb briquettes activated carbon 30. An exhaust pipe is fixedly installed on the top of the filter tank 14, and an exhaust fan 24 is installed inside the exhaust pipe.

[0034] It should be noted that by removing the fixing screw 21 from the second support block 19, the force fixing the annular seat 17 can be eliminated. The annular seat 17 can be rotated out of the replacement port, and the wire mesh demister 28, glass fiber board 29 and honeycomb briquette activated carbon 30 can be replaced or cleaned.

[0035] The exhaust fan 24 facilitates the removal of air from the filter canister 14.

[0036] In an optional embodiment: such as Figure 4 As shown, multiple sets of annular seats 17 have air rings 22 attached to their top and bottom. The sides of the air rings 22 are attached to the replacement port. An air tube 23 is connected to the air rings 22, and a sealing cap is installed on the air tube 23.

[0037] It should be noted that air is inflated into the inflation ring 22 through the inflation tube 23, so that the inflation ring 22 can fit tightly with the replacement port, and the contact position between the annular seat 17 and the replacement port is sealed to prevent smoke leakage. The inflation tube 23 can be sealed by the sealing cap.

[0038] In an optional embodiment: such as Figure 4 As shown, a first drain pipe 11 connected to the purification channel is installed on the side of the purification box 1, and a first drain valve 12 is installed on the first drain pipe 11.

[0039] It should be noted that excess oxidant can be stored on the other side of the baffle 31 and then discharged through the first drain pipe 11 by opening the first drain valve 12.

[0040] In an optional embodiment: such as Figure 1 and Figure 4 As shown, the side of the purification box 1 is connected to an air inlet pipe 4 for flue gas intake.

[0041] It should be noted that the flue gas can enter the purification chamber 1 for purification through the air inlet pipe 4.

[0042] In an optional embodiment: such as Figure 4 As shown, the bottom of the filter tank 14 is connected to a second drain pipe 25, and a second drain valve 26 is installed on the second drain pipe 25.

[0043] It should be noted that the water filtered by the wire mesh demister 28 can drip into the bottom of the filter tank 14 and be collected. The collected water can be discharged through the second drain pipe 25 by opening the second drain valve 26.

[0044] The usage process of this utility model is as follows: flue gas enters the purification channel through the air inlet pipe 4. The flue gas can be transported in the purification channel. The purification channel can extend the transport time of the flue gas inside the purification box 1, creating time conditions for the oxidant atomized droplets to fully react with harmful substances.

[0045] The extraction pump 5 is started. After the extraction pump 5 extracts the oxidant in the purification box 1 through the delivery pipe 6, it is transported to the main delivery pipe 7 through the delivery pipe 6 at the outlet of the extraction pump 5. After being transported to the main delivery pipe 7, the oxidant is transported through the delivery branch pipe 8. The oxidant atomized droplets are atomized and sprayed evenly onto the flue gas transported in the purification channel, increasing the gas-liquid contact surface area. At the same time, the atomized droplets of oxidant can be fully and evenly integrated into the flue gas, so that the flue gas and oxidant can react chemically, thereby oxidizing most of the compounds and elements in the waste gas to generate elemental molecules, solid particles, etc., so that the harmful substances in the flue gas are effectively separated, thereby improving the separation effect of harmful substances in the flue gas and improving the purification efficiency. Some of the atomized droplets of oxidant after separation of the flue gas can fall inside the purification channel.

[0046] After the harmful substances in the flue gas are separated once, they can be transported to the filter canister 14 through the connecting pipe 13. The wire mesh demister 28 can remove the mist droplets entrained in the flue gas. The glass fiber plate 29 can mechanically intercept the unpurified solid particles and liquid droplets in the flue gas, preventing solid particles from clogging the honeycomb briquette activated carbon 30 or liquid droplets from wetting the honeycomb briquette activated carbon 30 and affecting its use. The honeycomb briquette activated carbon 30 removes gaseous pollutants such as sulfur dioxide, nitrogen oxides, volatile organic compounds (VOCs), and formaldehyde from the flue gas. After purification, the flue gas is discharged through the exhaust pipe.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
