Abstract
The present invention relates to recovering and utilizing method and device for smoke purifying electrically trapped tar oil. The trapped tar oil is deposited in a container to separate out water and impurity precipitate before being pumped to the tar oil tank and provided to the roasting furnace for burning. The present invention is simple, low in cost, low in power consumption and environment friendly.
Description
Technical field:
The present invention relates to a kind of recoverying and utilizing method and device of closed purifying fume from calcining furnace electrically trapped tar oil, belong to electrically trapped tar oil recovery and utilization technology field.
Background technology:
In the graphite electrode of the production of carbon product, the roasting process of aluminium with the more raw product of bituminous amounts such as cathode carbon pieces, the flue gas that it produced contains more tar, for free from environmental pollution, usually the tar in the baking flue gas is captured with electrical tar precipitator in the prior art.The tar that electrical tar precipitator captures, its low heat value is approximately about 37KJ/g, and contains a certain amount of moisture and impurity.At present, because the tar that electrical tar precipitator is captured is when recycling, the technology more complicated of its recycling, and also therefore cost recovery usually abandon this part tar also than higher as refuse, and this not only wastes energy but also contaminated environment.
Summary of the invention:
The objective of the invention is: a kind of recoverying and utilizing method and device of recycling technology smoke purifying electrically trapped tar oil simple, with low cost is provided, to overcome the deficiencies in the prior art, the purpose of reach energy savings, protecting environment, reduce production costs.
The recoverying and utilizing method of smoke purifying electrically trapped tar oil of the present invention is: the flue gas of closed roaster is being adopted electrical tar precipitator capture tar in its flue gas when carrying out purified treatment, the tar that electrical tar precipitator captured is sent to carries out precipitation process in the container, make the tar of its precipitated processing in container, produce water-oil separating and contamination precipitation, send the tar of precipitated processing in the container back to the burning that acts as a fuel in the roaster more then.
The tar that electrical tar precipitator captured being sent to when carrying out precipitation process in the container, preferably make the time of its precipitation be not less than 10 hours, and preferably adopt steam-heated method to make the temperature in the container be not less than 60 ℃.
The recycle device of smoke purifying electrically trapped tar oil of the present invention is: it is by tar tank (1), oil strainer (2) and oil pump (3) are formed, be provided with the inflow pipeline (7) that can be connected with electrical tar precipitator (6) on the top of tar tank (1), be provided with the drainpipe (8) that has valve in the bottom of tar tank (1), the position that is higher than drainpipe (8) on tar tank (1) is provided with and can supplies with the petroleum pipeline (9) that the tar jar (4) of tar is connected with the burning rack (5) on roaster, and oil strainer (2) and oil pump (3) are installed in series respectively on petroleum pipeline (9).
On tar tank (1), be provided with steam-heating pipe (10).
Owing to adopted technique scheme, the present invention is transported to electrically trapped tar oil earlier and carries out precipitation process in the tar tank container, can discharge wherein moisture and impurity so effectively, then tar after treatment is transported to by oil pump after oil strainer filters in the tar jar of the burning rack supply tar on roaster again, uses with roasting fuel as roasting workshop roaster.The present invention in energy savings, reduce production costs in, also avoided the pollution of electrically trapped tar oil to environment.Therefore, the present invention compared with prior art, the present invention not only has and recycles the advantage that technology is simple, cost recovery is cheap, but also the advantage that has energy savings, protection environment, reduces production costs.
Description of drawings:
Accompanying drawing 1 is the structural representation of apparatus of the present invention.
The specific embodiment:
Embodiments of the invention: the flue gas of roaster is being adopted electrical tar precipitator capture tar in its flue gas when carrying out purified treatment, the tar that electrical tar precipitator captured is sent to carries out precipitation process in the container, make the time of its precipitation be not less than 10 hours, and preferably adopt steam-heated method to make the temperature in the container be not less than 60 ℃, can make the tar of its precipitated processing in container, produce water-oil separating and contamination precipitation so effectively, send the tar of precipitated processing in the container back to the burning that acts as a fuel in the roaster more then.
When implementing, preferably adopt the recycle device of smoke purifying electrically trapped tar oil of the present invention to implement, promptly adopt the container of tar tank (1) as precipitation usefulness, during making, install the inflow pipeline (7) that can be connected with electrical tar precipitator (6) on the top of tar tank (1), a drainpipe (8) that has valve is installed in bottom at tar tank (1), and the position that is higher than drainpipe (8) on tar tank (1) installs an energy and the burning rack (5) on roaster and supplies with the petroleum pipeline (9) that the tar jar (4) of tar is connected, and oil strainer (2) and oil pump (3) are installed in series respectively on petroleum pipeline (9); For safety with heat tar tank (1) easily, can around tar tank (1), install steam-heating pipe and (10).
