Abstract
The invention relates to a device for processing tar without water. The device comprises two oil-gas separators and a steam exhaust bag. The inlet of each oil-gas separator is connected with a mixed oil-gas pipeline through a mixed oil-gas three-way valve, and the outlet of each oil-gas separator is connected with a coal gas pipeline through a coal gas three-way valve. The two oil-gas separators are provided with a front set of steam tanks and a rear set of steam tanks respectively. The front set of steam tanks and the rear set of steam tanks are each provided with steam tank bodies. An oil scraper is arranged between every two adjacent steam tank bodies. A spiral oil conveyer is arranged at the lower portion of each oil-gas separator. An oil outlet is formed in the bottom of each oil-gas separator. Each steam tank body is provided with a steam inlet and a steam outlet. The steam inlets of the front set of steam tanks are each connected with a high-temperature steam pipeline through a high-temperature steam three-way valve and each connected with a low-temperature steam pipeline through a low-temperature steam three-way valve.
