Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and more specifically, to a waste gas treatment device for thermal cracking and recycling of waste tires. Background Art

[0002] During the heating process of the waste tire thermal cracking project, oil and gas will be produced. The oil and gas will be cooled into liquid oil through the cooling system. The gas that cannot be cooled is called tail gas. The tail gas contains a component called hydrogen sulfide. If the hydrogen sulfide is not removed, the tail gas will not be fully burned, the fire will be small, the heating will be insufficient, and the odor will spread in the workshop, which does not meet the requirements of environmental protection. Therefore, an exhaust gas treatment device is needed.

[0003] However, the current waste gas treatment device has poor thermal cracking effect on waste tires and poor removal effect on hydrogen sulfide. Most of them cause secondary pollution to the atmospheric environment after cracking. Therefore, in order to solve the above problems, a waste gas treatment device for thermal cracking and recovery of waste tires is specially proposed. Utility Model Content
