Definitions
- the invention relates to a kind of bacon, in particular to a chimney having multiple functions of anti-corrosion, dust collection and energy saving.
- the flue In existing chimneys, the flue is in the form of a straight line and is connected to the chimney through the tube core.
- the chimney of this structure has large resistance and does not collect dust, and the flue gas in the cylinder rises along the inner wall of the cylinder, delaying corrosion of the lining, often
- the liner is corroded and the cylinder is broken.
- the flue gas containing harmful sulfur dioxide produced by the industries such as smelting, power generation, and chemical industry is subjected to wet desulfurization treatment before it enters the smoke S, and this causes the temperature of the flue to fall below the dew point.
- the generated acid flows down the inner wall of the chimney, which can easily corrode the inner liner and eventually cause the cylinder to crack.
- the general method is to install an inner sleeve in the chimney. But such an inner sleeve is expensive. For example, a 210-meter chimney of a 600,000-kilowatt thermal power plant will cost 10 million yuan to build an inner casing investment, and the inner casing has a limited service life and needs to be replaced periodically or irregularly.
- the technical problem to be solved by the present invention is to overcome the above-mentioned defects existing in the existing chimney, and to provide an anti-corrosion dust-collecting and energy-saving chimney which has relatively low cost and has various functions of anti-corrosion, dust collection and energy saving.
- the technical solution of the present invention comprises a chimney cylinder, wherein the inner wall of the chimney cylinder is provided with an inner helix with a spiral angle of 10° to 80°, and a curved flue located outside the lower end of the chimney cylinder.
- the outlet is in communication with the inner helix.
- the arc direction of the curved flue is in the same direction as the spiral direction of the helix, and the arc flue is smoothly connected with the helix.
- the inner helix may be one to 30; the pitch of the inner helix (ie, the pitch, or the distance between two adjacent lines of an inner helix in the direction of the chimney of the chimney) may be 0. 5 meters to 20 meters.
- the beneficial result of the invention is: high structural stability and good environmental protection effect; compared with the existing chimney of the same height and the same emission, the environmental protection effect is improved by 25 to 45%, and the self-resistance is reduced by 20%, thereby reducing the induced draft fan.
- the power consumption is about 8.5%; the flue gas swirls in the cylinder, which is equivalent to a cyclone dust collector, which can collect dust by 30% ⁇ 80%; it also makes the chimney lining not corroded, the service life is greatly extended, and the cost is relatively low.
- the anti-corrosion dust-collecting and energy-saving bacon of the invention is suitable for the discharge of various types of flue gas.
- Figure 1 is a schematic structural view (partial cross-sectional view) of an embodiment of the present invention
- Figure 2 is a cross-sectional structural view of Figure 1A-A;
- Figure 3 is a schematic view of the swirling flow of the chimney of the chisel shown in Figure 1.
- the present embodiment includes a chimney cylinder 3 having an inner helix 1 having a helix angle of 60° on the inner wall of the chimney cylinder 3 and an arc outside the lower end of the chimney cylinder 3
- the outlet 2 of the flue 4 is in communication with the inward helix 1
- the arc direction of the arc flue 4 is in the same direction as the spiral direction of the intrinsic helix 1 (the same is right-handed), and the arc
- the flue 4 and the inward helix 1 are smoothly connected.
- the chimney cylinder 3 is constructed of inner bricks, and the bottom of the chimney cylinder 3 has a diameter of ⁇ 9 m and a height of 100 m.
- the percentage of the total height of the chimney is: the slope ratio is 20 to 30% of the total chimney, the slope ratio i 2 is 25 to 30% of the total height of the chimney, and the slope ratio i 3 is 20 to 25% of the total height of the chimney.
- Slope ratio i 4 accounts for the total height of the chimney 20 to 25%, slope i 5 accounted for 15 to 20% of the total height of the haze.
- the curved flue 4 of the chimney cylinder 3 is cut into the chimney with a smooth connection to the inner helix 1 and the inner helix 1 is spirally arranged on the inner wall of the chimney at an elevation angle of 60° so that the flue gas is inside the chimney
- the convolution forms a vortex, and the pitch of the inner helix 1 is 4 meters.
- the invention makes the flue-cured flue into a curved flue 4, the curved flue 4 is smoothly connected with the inner helix spiral 1, and the inner helix spiral 1 forms an inner helix spiral flue, which can make the flue gas in the chimney
- the inside of the cylinder 3 is swirled to form an outer swirling flow 5 and an inner swirling flow 6 (see Fig.
- the flue gas enters the chimney cylinder 3 from the curved flue 4, and can enter the chimney cylinder 3 before entering the curved flue 3 4 produces good rotation in advance, which helps to improve the dust removal efficiency, make the total pressure loss small, the dust content of the flue gas is greatly reduced, and the plume stiffness is large; the spiral structure on the inner lining (inner wall) makes the flue gas The flow maintains a spiral rise. Due to the centrifugal effect of the spiraling of the flue gas stream, a small amount of dust particles remaining in the flue gas stream are mainly distributed in the flue center. Condensation of the flue gas is related to the dust particles involved. The first is to form a condensation nucleus with the dust particles, and then gradually expand to form global condensation. Since dust particles are concentrated in the center of the flue, condensation occurs mostly in the middle axis of the flue, while the near-wall smoke still maintains an unsaturated state, and the wall is dry and free from condensed liquid corrosion.
- the anti-corrosion dust-removing and energy-saving chimney of the invention has good dust collecting effect, and the dust collection reaches 30 tons per hour; the energy saving is remarkable, and the power consumption of the induced draft fan can be reduced by 20%; after a long-term trial, even if the flue gas is wet dusted and wet The desulfurization treatment, the inner wall of the chimney is also intact, and there is no worry about corrosion.
- the anti-corrosion dust-collecting and energy-saving bacon of the invention is suitable for the discharge of various flue gases.
