AI Technical Summary

Technical Problem

In existing technologies, petrochemical waste gas enters the purification tank through a single inlet pipe and forms clumps, making it difficult for the chemical solution to fully cover the waste gas. As a result, some waste gas does not come into complete contact with the chemical solution, thus limiting the purification efficiency.

Method used

The exhaust system incorporates a multi-layer coil and a dispersing mechanism. The exhaust gas is dispersed through the vents of the multi-layer coil, and the dispersing rod breaks the exhaust gas into fine vortices, increasing the coverage of the liquid and improving the contact area between the exhaust gas and the liquid.

Benefits of technology

It effectively avoids the accumulation of waste gas clumps, increases the coverage of the liquid solution, and significantly improves purification efficiency.

Abstract

This utility model relates to the field of petrochemical waste gas treatment technology, and discloses a petrochemical waste gas purification device, including a purification tank. A valve connected to the lower end of the purification tank and communicating with its interior are fixedly connected to the lower end. An air inlet pipe is fixedly connected through the front surface of the purification tank. A spraying mechanism is arranged on the left side of the purification tank, and a combustion mechanism is arranged on the right side. An exhaust mechanism is arranged at the end of the air inlet pipe located inside the purification tank. By incorporating the exhaust mechanism, waste gas enters the multi-layered coil within the exhaust mechanism through the air inlet pipe, and is then dispersed and sprayed out through multiple air holes on the lower surface of the multi-layered coil. This design transforms the concentrated emission of waste gas from a single inlet into a multi-directional, multi-layered dispersed emission, forming a fine airflow that significantly increases the contact area with the chemical solution, preventing waste gas from accumulating in localized areas. The dispersing mechanism directly acts on the rising waste gas, preventing it from rapidly buoyant and forming clumps, thereby maximizing the coverage area of ​​the chemical solution.
