Abstract
The invention relates to a method and a device first using fuel oil to replace water to remove smoke dust. The effect can reach 100%, a large quantity of dust removing water can be saved, and sewage treatment cost can be omitted. The device enables the fuel oil to enter from the top of a duplex type overflow foaming tower and be discharged through the bottom of the tower. The device enables the smoke dust to enter from the bottom of the tower, rising waste gas blows the fuel oil in each multiporous plate to oil bubbles, the smoke dust in the oil bubbles is caught by oil films with adhesive performance multiple times stronger than that of water when striking the oil bubbles. When the waste gas rises to the first two layers of the top of the tower, the smoke dust is completely caught by the fuel oil bubbles, so that no smoke dust is discharged from the top of the tower. The fuel oil containing the smoke dust is filtered, the filtered oil is sent back to the tower for use, and filtering slag is used as boiler fuel. Therefore, the method for removing smoke dust almost has no cost and saves a large amount of capitals compared with various dust removing methods, and smoke dust removing can be executed automatically.
Description
At present, boiler waste gas is taken the trickle dedusting, but effect is unsatisfactory, looks at that the overhead cigarette dragon of U.S. power plant is just clear; The water dedusting except consuming a large amount of water rates, also wants substantial contribution to dispose of sewage, so the dedusting resistance is big.
At present, do not see the report of eliminating boiler smoke with fuel oil.What present technique proposed eliminates method and the device thereof that boiler smoke is saved water for dust removal with fuel oil 100%, is called for short this method and device thereof, can help to address the above problem.
Eliminate method and the device thereof that boiler smoke is saved water for dust removal with fuel oil 100%, its beneficial effect is: save water for dust removal and pollution treatment water rate usefulness fully, make producer reduce cost.
Eliminate method and the device thereof that boiler smoke is saved water for dust removal with fuel oil 100%, the technical scheme that its technical solution problem is adopted is, catches flue dust with fuel oil is sticking, usefulness again after containing flue dust fuel oil and filtering, and filter residue is made fuel; It sends boiler waste gas (1) into the compound overflow foaming tower (3) that fuel oil is housed with blower fan (2); With oil pump (4) compound overflow foaming tower contained flue dust fuel oil; Sending filtering tank (5) to filters; Send filter oil to compound overflow foaming tower with oil pump (6), filter residue is made fuel usefulness, thereby the method for using fuel oil 100% to eliminate boiler smoke saving water for dust removal is able to normal operation.Like Fig. 1
Blower fan is sent into dust-removing waste gas in the compound overflow foaming tower that fuel oil is housed again, when waste gas passes the porous of compound overflow foaming tower, fuel oil is blown out froth bed, and the flue dust of waste gas clashes into oil whip, is glued by the foam oil film and catches.Every cubic metre has 1,000,000 to 8,000,000 foams that waste gas is wrapped up in the compound overflow foaming tower, and makes waste gas in vacuole, roll, and makes sticking the catching of flue dust bump foam oil film.The big manyfold of viscosity ratio water of fuel oil is so fuel oil is to the sticking effect of catching of flue dust, than the big manyfold of water.Filter residue is made fuel usefulness, and water is not saved pollution treatment water rate usefulness, so use present technique smoke abatement and dust control, need not change money basically.
Below be described further through embodiment.
Compound overflow foaming tower is to carry out with fuel oil 100% to eliminate the device that boiler smoke is saved the method for water for dust removal.
Compound overflow foaming tower, its beneficial effect is: can pollution treatment water rate usefulness be saved in the flue dust full scale clearance, make smoke abatement and dust control not have resistance.
Compound overflow foaming tower, the technical scheme that its technical solution problem is adopted are by transparent tube (7), to be uniformly distributed with the porous plate (8) of aperture, overflow pipe (9), turnover gas-liquid pipe (10) composition; Its installation is, sealing transparent tube one end is with the polylith porous plate segment distance of being separated by; Be installed in the transparent tube; Overflow pipe passes porous plate, and overflow pipe upper end is near last block porous plate, and the overflow pipe lower end is near piece porous plate down; The sealing transparent tube other end is installed into out gas-liquid pipe at sealing transparent tube upper and lower side; Make compound overflow foaming tower (11) be able to normal operation.Like Fig. 1
Compound overflow foaming tower operation is introduced:
Exhaust gas and smoke gets at the bottom of tower, discharges from cat head; Fuel oil gets into from cat head, at the bottom of tower, discharges.Fuel oil is passed the waste gas of porous plate and is blown out vacuole; When the fuel oil alveolar layer exceeded overflow pipe, the fuel oil vacuole became fuel oil and stays on this porous plate from the porous plate of overflow mouth of pipe inflow lower floor; Passed the waste gas of this porous plate again and blown out the fuel oil alveolar layer; The fuel oil vacuole flows into the porous plate of a lower floor again from the overflow mouth of pipe, from again repeatedly, until being gone out by tower bottom flow.Control fuel oil flow makes a small amount of oil vacuole flow into the porous plate of one deck down from the overflow mouth of pipe; The control gas flow makes the two-layer preceding oil vacuole layer of cat head keep the former entering concentration of fuel oil, so near the three first layers of cat head, the flue dust in the waste gas is all glued by fuel oil and removes.
Every cubic metre can produce 1,000,000 to 8,000,000 foams waste gas is wrapped up in the compound overflow foaming tower, and makes flue dust in vacuole, roll.In the compound overflow foaming tower up to a hundred blocks of porous plates can be arranged, hold tens cubic metres of fuel oil foams; Overflow pipe makes the most foams of every layer of foam go the rounds tens times at this layer froth bed, makes tens bumps of fuel oil flue dust of every layer; In compound overflow foaming tower, ultra several thousand times of the fuel oil that flue dust bump viscosity ratio water is strong several times guarantees to get into the interior flue dust of compound overflow foaming tower by 100% sticking catching.
The Figure of description explanation:
1. boiler waste gas, 2. blower fan, 3. compound overflow foaming tower, 4. oil pump, 5. filtering tank, 6. oil pump, 7. transparent tube, 8. porous plate, 9. overflow pipe, 10. turnover gas-liquid pipe, 11. compound overflow foaming towers.
