Description

Technical Field

[0001] The utility model belongs to the technical field of industrial waste gas treatment, and specifically relates to an industrial waste gas combustion device. Background Art

[0002] Waste gas emitted from industrial production often has harmful effects on the environment and human health. Purification measures should be taken before it is discharged into the atmosphere to make it meet the requirements of waste gas emission standards. This process is called waste gas purification. Commonly used waste gas purification methods include absorption, adsorption, condensation and combustion. Among them, the combustion method is a method of converting combustible and harmful components in waste gas into harmless substances or substances that are easy to further process and recycle through thermal oxidation. The combustion method is only suitable for purifying combustible or high-temperature decomposable substances. Organic waste gas is generally flammable and suitable for combustion treatment.

[0003] When in use, the traditional catalytic combustion device for industrial waste gas will only perform a combustion catalytic treatment on the industrial waste gas. When the industrial waste gas flow rate is fast, incomplete treatment is likely to occur. Based on this, the utility model provides an industrial waste gas combustion device. Utility Model Content

The use of a gas pipe and a combustion nozzle can form a downward-jetting flame and an upward-jetting flame in the combustion box. When the industrial waste gas enters the combustion box, the industrial waste gas first contacts the flame at the bottom of the gas pipe and passes through the bottom catalytic plate. At this time, the industrial waste gas can be initially burned. The industrial waste gas then moves upward to contact the flame at the top of the gas pipe and passes through the top catalytic plate. At this time, the industrial waste gas can be burned again. By performing two combustion catalytic treatments on the industrial waste gas, harmful components in the industrial waste gas can be effectively removed, which is convenient for the treatment of the industrial waste gas.
