Method and device for fathering bitumen waste gases

Abstract

The invention discloses asphalt waste gas governing method, wherein, the procedure is that after the waste gas is concentrated by a collecting pipeline, cooling and purification are carried out through a spray pump purification tower, and partial oily substance is condensed and intercepted in the spray pump purification tower; after repeated circulation, oil content of the oily substance is recycled; the remain water is continued to be absorbed circularly in the spray pump purification tower; waste gas purified in the spray pump purification tower enters an oil bathing tank and a plasma oxidizer to be further processed, and then is discharged through an induced draft fan when reaching the mark. An equipment used for processing the asphalt waste gas by the method is also provided by the invention. The invention has the advantages that advantages of various asphalt waste gas governing techniques are synthesized; the running cost is low; the purification efficiency is high; the invention can be widely applied to asphalt waste gas engineering governance.

Description

technical field [0001] The invention relates to waste gas treatment technology, in particular to a treatment method and device for asphalt waste gas. Background technique [0002] Asphalt is a brown-black organic gelatinous substance, including natural asphalt, petroleum asphalt, shale asphalt and coal tar asphalt. The main components are asphaltene and resin, followed by high boiling point mineral oil and a small amount of oxygen, sulfur and chlorine compounds. Glossy, liquid, semi-solid or solid state, brittle at low temperature, good adhesion and anti-corrosion performance. [0003] Asphalt is widely used in many industries due to its stable properties, high temperature resistance and flammability. [0004] (1) Asphalt is further processed to obtain asphalt fiber, which is then carbonized to make carbon fiber, which is an important reinforcement of high-quality carbon fiber composite materials. This is an advanced application of asphalt. [0005] (2) Petroleum pitch ca...

AI Technical Summary

Problems solved by technology

Among them, the washing method has relatively low investment and cost, and is more suitable for small and medium-sized enterprises; the combustion method is suitable for high-concentration organic waste gas. When it is used for the treatment of low-concentration waste gas, the energy consumption increases sharply, and the operating cost is unacceptable; The key to getting it right is to find a suitable adsorbent in combination with the actual production situation (for example, alumina is often used as the adsorbent in the electrolytic aluminum industry, and the saturated alumina is returned to the electrolytic cell as the raw material for production, which solves the problem of the adsorbent very well. ); the high-voltage electrostatic method has a large investment and is generally used in large enterprises. The operation cost of this method is low, but there are also problems such as difficult scraping of the captured asphalt
