Drying device and asphalt station
The invention provides a drying device and an asphalt station. The drying device comprises a reducing agent storage tank, a pump, a drying drum, a combustor and a spraying device; the input end of thepump is communicated with the reducing agent storage tank; the combustor is arranged in the drying drum; and the spraying device is communicated with the output end of the pump and is arranged in thedrying drum. During the use of the drying device, the combustor is used for drying a cold material by combusting heavy oil, and the pump is started in the process; the pump pumps a reducing agent inthe reducing agent storage tank to the spraying device; the spraying device sprays the reducing agent out; the reducing agent and nitrogen oxide generated by the heavy oil combustion of the combustorcan be subjected to a reduction reaction, so that nitrogen and water are generated, and therefore, a nitrogen oxide in waste gas generated by the combustion of the combustor are removed, and the content of the nitrogen oxide in the waste gas is reduced.
本发明提供了一种烘干装置和沥青站，其中，烘干装置包括：还原剂存储罐；泵，所述泵的输入端连通于所述还原剂存储罐；烘干滚筒；燃烧器，所述燃烧器设置在所述烘干滚筒内；喷淋装置，所述喷淋装置连通于所述泵的输出端，设置在所述烘干滚筒内。本发明提供的烘干装置，在使用过程中，燃烧器通过燃烧重油对冷料进行烘干，在此过程中开启泵，泵将还原剂存储罐内的还原剂泵送至喷淋装置，喷淋装置将还原剂喷出，还原剂即可与燃烧器重油燃烧产生的氮氧化物进行还原反应，生产氮气和水，从而脱除燃烧器燃烧产生的废气中氮氧化物，降低了废气中氮氧化物含量。
