Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, a treatment system for oil washing regeneration residue flue gas mainly includes an exhaust cleaning system and a high temperature incineration treatment system. The exhaust cleaning system mainly includes a flue gas cleaner, cleaning oil tank and exhaust cleaning The high-temperature incineration treatment system mainly includes an incinerator, a heat transfer oil heat exchanger and a flue gas preheater. The asphalt flue gas first passes through the exhaust cleaning system for absorption and dissolution operation, and then enters the high-temperature incineration treatment system for incineration and purification;

[0019] The details are as follows: the asphalt fume generated by each equipment in the tar processing area is sent to the flue gas scrubber, fully mixed with the washing oil in the flue gas scrubber, and the washed flue ga...

Abstract

The invention discloses a treatment system for oil-washing regeneration residue flue gas. The system mainly comprises an exhaust cleaning system and a high-temperature incineration treatment system. Asphalt flue gas generated by all devices in a tar processing area is absorbed and dissolved through the exhaust cleaning system, then enters the high-temperature incineration treatment system to be incinerated and purified, and finally the treated flue gas is exhausted to the atmosphere. According to the treatment system, an exhaust cleaning system and a high-temperature incineration treatment system are combined, i.e., an asphalt flue gas treatment process combining an absorption method and an incineration method is employed; therefore, the system has the advantages of operability, lower costand good purification effect, conforms to the actual tar processing and production, and can thoroughly solve the problem of pollution of asphalt flue gas of a tar processing plant, thereby achievingthe purpose of harmless emission; the emission concentration and the emission rate of each pollutant after asphalt flue gas treatment of the system reach the secondary emission standard of "IntegratedEmission Standard of Atmospheric Pollutants".

Description

technical field [0001] The invention belongs to the technical field of tar processing and environmental protection treatment, and in particular relates to a treatment system for oil washing regeneration residue flue gas. Background technique [0002] Tar processing is a traditional high-pollution industry. During the production, storage and transportation of asphalt, a large amount of toxic asphalt fumes will be generated, which will cause harm to humans and animals. Asphalt fume contains benzo(a)pyrene, which is extremely carcinogenic. If it is exposed to asphalt fume pollution for a long time, it can cause respiratory and skin diseases and induce cancer. In order to effectively control and control the pollution of asphalt fume, the "Emission Standards of Air Pollutants" has express regulations on the emission of industrial asphalt fume. For new tar processing plants, the maximum allowable emission concentration of asphalt fume is 40mg / m 3 , the maximum allowable emission ...
