Description

Technical Field

[0001] The invention belongs to the technical field of tail gas treatment devices, and in particular relates to a tail gas treatment device and a treatment process for sulfuric acid production. Background Art

[0002] The tail gas produced in the sulfuric acid production process contains various sulfide gases, which cause great pollution to the environment. Recycling them can not only reduce air pollution, but also produce various sulfide products. In the tail gas treatment process, different removal methods need to be adopted according to the characteristics of different gases. Among them, sulfur dioxide in the tail gas can be treated by ammoniation method and produce products such as ammonium sulfate. In the prior art, sulfur dioxide is absorbed by recycling ammonia water, but the sulfur dioxide content in the tail gas changes all the time, which will lead to insufficient or insufficient use of ammonia water, affecting the progress of the reaction.

[0003] After searching, in the prior art, Chinese patent publication number CN115624851B, authorization announcement date: 2023-03-31, discloses a process and device for treating tail gas from electronic-grade sulfuric acid production. The device for treating tail gas from electronic-grade sulfuric acid production includes a waste gas tank, an ammonia water storage tank and multiple absorption tanks; the waste gas in the waste gas tank and the ammonia water in the ammonia water storage tank flow through multiple absorption tanks in sequence; each absorption tank is provided with a spray assembly that can slide up and down, and the spray assembly can adjust the amount of ammonia water entering. The process for treating tail gas from electronic-grade sulfuric acid production first determines the amount of ammonia water entering the absorption tank according to the sulfur dioxide content Q in the waste gas entering each absorption tank, so that the ammonia water in each absorption tank matches the waste gas to be desulfurized, thereby ensuring the working efficiency of each absorption tank; after a preset time, the pH value H of the ammonia water after the waste gas is absorbed by the lower part of the absorption tank is obtained to judge the absorption effect of ammonia water on sulfur dioxide in the waste gas, and the desulfurization effect of ammonia water is ensured by adjusting the height of the spray assembly.

[0004] However, the equipment still has the following defects: although it is possible to determine the absorption effect of ammonia water on sulfur dioxide in the exhaust gas by obtaining the pH value H of ammonia water after absorbing the exhaust gas in the lower part of the absorption tank, and ensure the desulfurization effect of ammonia water by adjusting the height of the spray assembly, it requires the use of multiple sets of spray assemblies to extend the spraying time.

[0033] The embodiment of the present invention provides a sulfuric acid production tail gas treatment device, including a waste gas tank 1 and an ammonia water storage tank 2; illustratively, as Figure 1 and Figure 2 shown.

[0034] The ammonia water storage tank 2 is located on one side of the waste gas tank 1, and an exhaust gas treatment component 3 is arranged between the waste gas tank 1 and the ammonia water storage tank 2.

[0044] The dust collecting box 3511 is an open cylindrical structure, and a plurality of isolation holes 3512 are provided at the bottom of the dust collecting box 3511, and metal filters are provided on the surfaces of the plurality of isolation holes 3512.

[0045] The mixing portion 352 includes a liquid collecting seat 3521; illustratively, as Figure 7 shown.

[0046] A plurality of groups of air inlet pipes 3522 are embedded and installed on the surface of the liquid collecting seat 3521, and a plurality of groups of air exhaust holes 3523 are opened on the outer walls of the plurality of groups of air inlet pipes 3522, and a sealing sleeve 3524 is sleeved on the bottom end of the plurality of groups of air inlet pipes 3522, and the bottom end of the sealing sleeve 3524 is movably connected to the bottom end of the inner wall of the storage tube 311, and the sealing sleeve 3524 is staggered with the through hole 313, and activated carbon fillers 3525 are arranged in the plurality of groups of air inlet pipes 3522, and the top ends of the plurality of groups of air inlet pipes 3522 are connected to the inner wall of the isolation hole 3512, and the activating carbon fillers 3525 are arranged in the plurality of groups of air inlet pipes 3522, and the top ends of the plurality of groups of air inlet pipes 3522 are connected to the inner wall of the isolation hole 3512, and the activating carbon fillers 3525 are arranged in the plurality of groups of air inlet pipes 3522, and the activating carbon fillers 3525 are connected to the inner wall of the isolation hole 351 ... A sealing ring 3526 is provided on the outer wall of the carbon filler 3525, and the sealing ring 3526 is movably connected to the inner wall of the storage tube 311, and a plurality of groups of first overflow holes 3527 are opened on the inner wall of the liquid collecting seat 3521, and a plurality of groups of second overflow holes 3528 are opened at the bottom and near the edge of the liquid collecting seat 3521, and the plurality of groups of second overflow holes 3528 are interconnected with the first overflow holes 3527, and a side wall of the liquid collecting seat 3521 is fixedly connected to the end of the linkage block 34, and a side wall of the liquid collecting seat 3521 is interconnected with the end of the telescopic tube 38.

[0047] Specifically, the assembly hole 3514 is sleeved on the end of the first pipe 4 to collect the exhaust gas, and the exhaust gas is concentrated into the dust collection box 3511. The metal filter screen on the surface of the isolation holes 3512 is used to initially isolate the particulate matter in the exhaust gas. Then, the exhaust gas after the particulate matter is removed is contacted with the activated carbon through the intake pipe 3522 interconnected with the isolation holes 3512. The exhaust gas enters the intake pipe 3522 and is adsorbed and filtered. Then, the exhaust holes 3523 opened around the intake pipe 3522 are used to evenly release the exhaust gas to the inside of the storage tube 311 and the bottom of the liquid collection seat 3521.

[0048] The continuous operation of the self-priming pump 36 sucks the spray liquid stored in the temporary storage tank 32 and transfers it to the liquid collection seat 3521. The overflowing spray liquid is distributed around the bottom edge of the liquid collection seat 3521 through the plurality of groups of first overflow holes 3527 and second overflow holes 3528 in the liquid collection seat 3521 to form a spraying effect on the exhaust gas. The spray liquid is made to flow into the temporary storage tank 32 again through the through hole 313 to eliminate the film formed by the traditional spray liquid in the spray tower, thereby improving the removal or conversion of pollutants in the exhaust gas.

[0049] The output end of the electric push rod 33 drives the linkage block 34 to fall, so that the liquid collecting seat 3521 falls synchronously, and the sealing sleeve 3524 is sleeved on different positions of the air inlet pipe 3522 to close the exhaust holes 3523 at different heights on the surface of the air inlet pipe 3522, thereby reducing the number of exhaust holes 3523 and adjusting the amount of exhaust gas discharged from the exhaust holes 3523. After the liquid collecting seat 3521 falls synchronously, the distance between it and the bottom of the storage tube 311 is shortened, shortening the time for the first overflow hole 3527 and the second overflow hole 3528 to let the spray liquid fall, making the spray frequency of the spray liquid on the exhaust gas more intensive, thereby improving the spraying efficiency.

[0050] The working principle of the sulfuric acid production tail gas treatment device proposed in the embodiment of the present invention is as follows:

[0051] The exhaust gas is sleeved on the end of the first pipe 4 through the assembly hole 3514 to collect the exhaust gas and collect it in the dust collection box 3511. The metal filter screen on the surface of the isolation holes 3512 is used to initially isolate the particulate matter in the exhaust gas. Then, the exhaust gas after the particulate matter is removed is contacted with the activated carbon through the intake pipe 3522 interconnected with the isolation holes 3512. The exhaust gas enters the intake pipe 3522 for adsorption and filtration. Then, the exhaust holes 3523 opened around the intake pipe 3522 are used to evenly release the exhaust gas to the inside of the storage tube 311 and the bottom of the liquid collection seat 3521.

[0052] The spray liquid stored in the temporary storage tank 32 is sucked in by the continuous operation of the self-priming pump 36 and transferred to the liquid collecting seat 3521. The overflowing spray liquid is distributed around the bottom edge of the liquid collecting seat 3521 through a plurality of groups of first overflow holes 3527 and second overflow holes 3528 in the liquid collecting seat 3521 to form a spraying effect on the exhaust gas. The spray liquid is made to flow into the temporary storage tank 32 again by the through hole 313 to eliminate the film formed by the traditional spray liquid in the spray tower and improve the removal or conversion of pollutants in the exhaust gas.

[0053] The linkage block 34 is driven to fall by the output end of the electric push rod 33, and the liquid collecting seat 3521 falls synchronously. At the same time, the sealing sleeve 3524 is sleeved on different positions of the air inlet pipe 3522 to close the exhaust holes 3523 at different heights on the surface of the air inlet pipe 3522, thereby reducing the number of the exhaust holes 3523 and adjusting the amount of exhaust gas discharged from the exhaust holes 3523. After the liquid collecting seat 3521 falls synchronously, the distance between it and the bottom of the storage tube 311 is shortened, shortening the time for the first overflow hole 3527 and the second overflow hole 3528 to let the spray liquid fall, making the spray frequency of the spray liquid on the exhaust gas more intensive, thereby improving the spraying efficiency.

[0054] Based on the above-mentioned sulfuric acid production tail gas treatment device, the embodiment of the present invention also provides a treatment process of the sulfuric acid production tail gas treatment device, including the following steps:

[0055] The exhaust gas tank transfers the exhaust gas to the exhaust gas treatment component through the first pipeline;

[0056] The treated tail gas is transferred to the ammonia water storage tank through the second pipeline by the tail gas treatment component.
