Abstract
The invention discloses a method and an apparatus for centrifugally separating asphalt tar in asphalt flue gases. The method comprises: flow asphalt smoke of an asphalt smoke system enters into a cylinder body (1) and drives guide vanes (4) in the cylinder body (1) for rotary motion in the cylinder body, and thus rotation is generated during progression of the smoke, and asphalt tar in the smoke is isolated under the effect of centrifugal force during rotation; the isolated asphalt tar attaches to the wall of the cylinder, and parts of the asphalt tar automatically flows to the bottom of the cylinder body under the effect of gravity; and the driving guide vanes (4) drives scraping plates (5) for rotation, and the scraping plates (5) scrape the tar solidified on the cylinder wall during movement, and the tar are discharged via a cone-shaped hopper (6) and a discharge port (7). According to the method and the apparatus of the invention, the adherence thickness of asphalt on the cylinder wall can be reduced, normal running of the apparatus is guaranteed, condensation of asphalt tar is promoted and purifying efficiency of the system is raised better.
Description
Technical field
The present invention relates to a kind of method and device of separate bitumen flue gas medium pitch tar.
Background technology
At present in the bitumen flue gas treatment system, generally directly utilize pipeline to be connected to equipment, perhaps in pipe-line system, increase a subsider converged, do not take effective means to concentrate pretreatment, therefore tarvia is directly brought into the treatment facilities such as sack cleaner or electrical tar precipitator by flue gas, increased the load of equipment, and the sack cleaner treatment system purified for adsorbing powder dust, controlling the bad dust adhering that will cause gets lodged in above filter bag, make normally deashing operation of filter bag, sack cleaner was lost efficacy.For the system of electrical tar precipitator treatment and purification, the bitumen flue gas excessive concentration will cause the electric fishing electric discharge frequent, if cleaning not in time, even likely cause on fire or blast, increase the danger of system.
Summary of the invention
The object of the invention is to: method and device that a kind of centrifugation bitumen flue gas medium pitch tar is provided, under the prerequisite of not setting up external power source or power gas, tarvia in flue gas is carried out to pretreatment, reduce the concentration of the tarvia in flue gas, reduce the load of subsequent processing device, raising system reliability of operation, improve the purification efficiency of flue gas purification system simultaneously, directly by flue gas, brought into the treatment facilities such as sack cleaner or electrical tar precipitator to overcome the tarvia that prior art exists, increase machine utilization, controlling bad meeting causes dust adhering to get lodged in above filter bag, make normally deashing operation of filter bag, make the deficiencies such as sack cleaner inefficacy.
The method of centrifugation bitumen flue gas medium pitch tar of the present invention, by the following technical solutions: the mobile bitumen flue gas of bitumen flue gas system enters cylindrical shell, the guide vane that mobile bitumen flue gas promotes in cylindrical shell rotates in cylindrical shell, make flue gas produce rotation in the process of advancing, and the effect due to centrifugal force is separated the tarvia in flue gas in the process of rotation; Be attached to barrel after tarvia is separated, the part tarvia flows automatically to the bottom of cylindrical shell under Action of Gravity Field; Guide vane rotarily drives the scraper plate rotation, and the tar that scraper plate will be set in barrel in the process of motion scrapes, and by taper bucket and discharge gate, discharges.
The device of centrifugation bitumen flue gas medium pitch tar of the present invention, by the following technical solutions: the cylindrical shell two ends arrange respectively air inlet and air outlet, be provided with guide vane in cylindrical shell, the periphery of guide vane is connected with scraper plate, the cylindrical shell bottom is provided with the taper bucket, and the bottom of taper bucket is provided with discharge gate.
Guide vane and scraper plate adopt and are welded to connect.
Scraper plate is pressed close to cylindrical shell wall layout, is wedge structure, and lateral surface is arcuate structure, parallel with the cylindrical shell wall, is fixed on rotating frame fixing together with guide vane.
The taper bucket can be collected the solid asphalt that scraper plate scrapes.
Compared with the prior art, the present invention is by utilizing flue gas flowing in cylindrical shell, promote the rotation of guide vane in cylindrical shell, under the turning effort of guide vane, drive the flue gas shape motion of spinning in cylindrical shell, thereby the tarvia in flue gas is separated with flue gas under the effect of inertia force, on the cylindrical shell wall under condensation, and be attached on the cylindrical shell wall.The solid asphalt that the scraper plate of guide vane periphery will be attached on the cylindrical shell wall in motion process scrapes, effectively collect on the one hand the solid asphalt of condensation, in time barrel is cleared up on the one hand in addition, reduce the adhesion thickness of pitch at barrel, in the long-term normal operation of assurance equipment, promote the condensation of tarvia, better improved the purification efficiency of system.Therefore the present invention has good promotional value and use value.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is blade structure schematic diagram of the present invention;
The A that Fig. 3 is Fig. 2 is to figure.
The specific embodiment
Embodiments of the invention: the method for centrifugation bitumen flue gas medium pitch tar of the present invention is as follows: the mobile bitumen flue gas of bitumen flue gas system enters cylindrical shell 1, the guide vane 4 that mobile bitumen flue gas promotes in cylindrical shell 1 rotates in cylindrical shell, make flue gas produce rotation in the process of advancing, and the effect due to centrifugal force is separated the tarvia in flue gas in the process of rotation; Be attached to barrel after tarvia is separated, the part tarvia flows automatically to the bottom of cylindrical shell under Action of Gravity Field; Guide vane 4 rotarily drives scraper plate 5 rotations, and the tar that scraper plate 5 will be set in barrel in the process of motion scrapes, and by taper bucket 6 and discharge gate 7, discharges.
The device of centrifugation bitumen flue gas medium pitch tar of the present invention, as shown in Figure 1, comprise cylindrical shell 1, there are respectively air inlet 2 and air outlet 3 in cylindrical shell 1 two ends, and guide vane 4 is arranged in cylindrical shell 1, and the periphery of guide vane 4 has scraper plate 5, taper bucket 6 is arranged at cylindrical shell 1 bottom, and discharge gate 7 is arranged at the bottom of taper bucket 6.
In use, flue gas enters cylindrical shell 1 from air inlet 2, and the guide vane 4 driven in cylindrical shell 1 rotates, under the effect of guide vane 4 revolving forces, spin in cylindrical shell 1 shape operation of flue gas, tarvia is split into cylindrical shell 1 wall and is condensed under the effect of centrifugal force, through the flue gas separated, from air outlet 3, discharge, the pitch be condensed is scraped by scraper plate 5, falls into taper bucket 6, by discharge gate 7, regularly discharges.
