Description

Technical Field

[0001] The utility model relates to the technical field of acid smoke emission, and particularly relates to a device for treating unorganized acid smoke emissions. Background Art

[0002] In recent years, the state has attached great importance to environmental protection and the occupational health of personnel on chemical production lines. However, due to the wide layout and large floor area of chemical production lines, and safety factors, they cannot be centrally arranged, resulting in non - centralized distribution of leakage points. It is difficult to effectively manage the problem of unorganized emissions. Coupled with the high cost of environmental protection treatment devices, the treatment cost is high. Eventually, the problem of unorganized emissions of acidic gases is widespread. For example, in areas such as the tank farms, transfer storage tanks, wastewater ponds, and residual liquid ponds of volatile inorganic acidic gases such as sulfuric acid and nitric acid in chemical production lines, during the process of receiving and sending materials in this area, acidic corrosive and toxic acidic gases are often generated. These gases are in a state of unorganized emissions, and the acid smoke is directly discharged into the atmosphere, spreading to the production area and the surrounding roads. This not only deteriorates the on - site working environment, poses a health hazard to operation and inspection personnel, but also poses a certain corrosion risk to equipment and pipelines. At the same time, it pollutes the surrounding environment, which does not meet the requirements of "zero pollution and zero emissions" for safety and environmental protection. The phenomenon of unorganized acid smoke emissions is a potential major safety and environmental protection risk hazard. Therefore, designing a device for treating unorganized acid smoke emissions has become the research direction of scholars.

[0003] However, the traditional acid smoke emission devices cannot meet people's needs, and they have the following defects: First, there is no designed acid smoke collection and absorption device, so it is impossible to centrally treat the unorganized acidic gases distributed in chemical production lines, and it cannot improve the on - site working environment, cannot effectively absorb and treat acidic gases, and cannot provide a solution to the risks of the surrounding environment; Second, there is no designed simple device body. For the acid smoke absorption device, the required cost is high, and it is impossible to adjust the equipment treatment capacity according to the amount of acidic gases, and it cannot be arranged at multiple points in the required site, so it cannot solve the common problem of difficult tail gas emission treatment that generally exists in most chemical enterprises.

[0021] Working principle: When using the present utility model for acid fume treatment, first, the equipment is inspected to confirm that it is correct. According to the calculated plan, the device is arranged at multiple points for acid fume collection and treatment. Deionized water is added to the absorption tank 1 through the deionized water make-up pipe 18 to provide a power source for the absorption of acid fume. The forced circulation pump 7 is started by controlling through the central control device. At the same time, the acid-containing unorganized emission gas is collected through the intake pipe 13 and discharged into the gas-liquid separator 12. The separated gas is discharged into the ejector pump 11 through the gas flow pipe 14.
