Description
Technical Field
The utility model relates to the technical field of asphalt flue gas, in particular to a high-temperature asphalt flue gas recovery system.
Background
Asphalt fume is a harmful substance generated in the industrial production process of asphalt, and is toxic and harmful per se and complex and various in components. The flue gas contains various organic matters including carbon cyclic hydrocarbon, cyclic hydrocarbon derivatives and other compounds, and has a great harm effect on human health. In the process of collecting, conveying and eliminating smoke of asphalt fume, liquid-solid asphalt is easily adhered to the surfaces of pipelines and equipment. The solidified asphalt is difficult to remove, so that the pipeline is often blocked and equipment is often damaged, and the system cannot normally operate. In addition, asphalt smoke components are extremely complex and vary from asphalt source to asphalt source. The asphalt fume contains solid and liquid particles formed by condensing volatile components of asphalt and vapor organic matters, and part of the organic matters are high-molecular polymers, so that serious pollution to the environment is caused.
At present, the methods for purifying and treating asphalt flue gas at home and abroad mainly comprise an incineration method, an absorption method, an electric fishing method and an adsorption method. The burning method is to burn hydrocarbon, combustible carbon powder and tar mist in the flue gas and decompose the hydrocarbon, the combustible carbon powder and the tar mist into CO and H 2 O. However, the method has high combustion temperature, requires the combustion material to reach a certain concentration, can burn, has strict control of combustion time, is easy to cause incomplete combustion and secondary pollution, and has high investment and operation cost. The absorption method is to directly contact the asphalt fume with organic liquid (washing oil) to make the tar particles and fume coagulate and sink down, thus achieving the purpose of purifying the asphalt fume. However, the process can produce sewage, cause secondary pollution, has low purification efficiency and has more operation problems of a flue gas purification system. The electric trapping method is to trap tar by high-voltage static electricity. And applying direct-current high voltage between the corona electrode (negative electrode) and the precipitation electrode to discharge the corona electrode and ionize the flue gas to generate a large amount of positive ions and negative ions. The positive and negative ions meet and charge tar mist drops in the process of moving to the corona electrode and the precipitation electrode, and the mist drops are attracted by the electrode and removed. The electric catching method has certain requirements on smoke concentration and smoke specific resistance. The adsorption method uses various powder materials with very high porosity and large specific area as adsorbents to purify asphalt fume. The method is thatMixing the adsorbent with the flue gas, and purifying harmful components in the gas phase through molecular absorption of the adsorbent. The method has the advantages of low investment, low running cost, convenient operation and maintenance, but low adsorption efficiency.
