Description

Technical Field

[0001] The utility model relates to the technical field of sulfuric acid production, in particular to a dilution device for sulfuric acid production. Background Art

[0002] In the production process of sulfuric acid, dilution is a crucial link. However, this link is accompanied by a problem that cannot be ignored: the sulfuric acid vapor produced during the dilution process will be directly discharged into the external environment, causing serious air pollution.

[0003] Once released into the atmosphere, these sulfuric acid vapors will undergo complex chemical reactions with other substances in the air to form various harmful compounds. These compounds will not only have a serious impact on air quality, but may also pose a potential threat to human health. Long-term inhalation of these harmful substances may cause respiratory diseases or even more serious health problems. In addition, the emission of sulfuric acid vapor also poses a threat to the ecological environment. They may have a negative impact on plant growth, destroy the ecological balance, and thus affect the stability of the entire ecosystem.

[0004] Therefore, for the dilution process of sulfuric acid production, we must take practical and effective measures to reduce the emission of sulfuric acid vapor. This is not only responsible for environmental protection, but also respect for human health and ecological balance.

[0005] This device is specially designed to treat the tail gas generated in the dilution process of sulfuric acid production, achieving the effect of pollution-free emission. Utility Model Content

[0006] In order to overcome the disadvantage that the tail gas released during the dilution of the existing sulfuric acid contains harmful gases and causes pollution to the atmosphere, the utility model aims to provide a dilution device for sulfuric acid production with tail gas treatment.

[0007] A dilution device for sulfuric acid production comprises a working bottom plate, a dilution reactor and a cooling box. The dilution reactor and the cooling box are both arranged on the working bottom plate. The dilution reactor is connected to the cooling box through a pipeline. The dilution reactor also comprises a treatment box, an air intake pipe, a decomposition liquid storage box, a water pipe, a water pump and a nozzle. The treatment box is connected to the cooling box through the air intake pipe. A decomposition liquid storage box is arranged at the lower part of the treatment box. The water pipe connects the treatment box and the decomposition liquid storage box. One end of the water pipe located at the decomposition liquid storage box is connected to the water pump. One end of the water pipe located at the treatment box is connected to the nozzle. The nozzle is fixed to the top surface of the treatment box through a fixing block.

[0008] A more excellent solution is that a drain port is provided inside the processing box, the processing box is connected to a waste liquid tank via the drain port, and the waste liquid tank is provided with a drain valve.

[0009] A more excellent solution is to further include a partition and an activated carbon filter element. The partition is arranged in the processing box and divides it into two parts. The nozzle is located at the air inlet part of the processing box, and the activated carbon filter element is arranged at the air outlet part of the processing box.

[0010] A more excellent solution is that a plurality of holes are provided on the partition, and the activated carbon filter is located at the gas outlet portion of the treatment box.

[0011] A more excellent solution is to further include an exhaust fan, which is arranged at the air outlet part of the processing box.

[0012] A more excellent solution is to further include an anti-skid pad, and the pipe valve handle is provided with an anti-skid pad.

[0013] A more excellent solution is to further include an observation window and a scale, wherein both the decomposition liquid storage tank and the waste liquid tank are provided with an observation window, and a scale is arranged on the observation window.

[0014] A more excellent solution is to further include a stabilizing frame, which is fixedly connected to the outside of the decomposition liquid storage box and supports and fixes the water pipe.

[0015] The beneficial effects are as follows: the gas generated when sulfuric acid is diluted is introduced into the treatment box through the air inlet pipe, the water pump is turned on to introduce the decomposition liquid from the decomposition liquid storage box into the water pipe, and then the nozzle at the upper end of the water pipe is used for atomization spraying, so that the decomposition liquid can fully neutralize the residual gas, effectively reducing the harmfulness of the gas.
