Description
Technical field
Flue-gas dust removal and purification device belongs to the udst separation field of flue gas.It is a kind of flue-gas dust removal and purification device of efficient, energy-saving and environmental protection.
Background technology
Along with rapid economic development, the overall national strength of China strengthens day by day, pillar industries such as chemical industry, the energy, metallurgy, electric power have been made huge contribution to the national economy of China, yet the waste gas that heavy industry produces has caused serious pollution to the atmospheric environment of China.As one be the country of main energy sources with coal, according to data over the years estimation, the atmosphere pollution that combustion process produces accounts for 70% of atmosphere pollution total amount, wherein coal fire discharged amount then accounts for 96% of whole burning and exhausting amount.The coal-fired harmful substance that produces accounts for very big proportion in discharge capacity, wherein flue dust accounts for 60% of total release, and sulfur dioxide accounts for 87% of total release, and nitrogen oxide accounts for 67% of total release.As seen, the atmosphere pollution of China is to be the coal-smoke pollution of feature with discharging flue dust and sulfur dioxide typically.For living environment, in order to stay a slice clear water blue sky to the descendant, the improvement of air environmental pollution is primary task.
At present, aspect air contaminant treatment, most of enterprises all adopt technology such as cloth-bag type dedusting, electric precipitation and cyclone dust removal, and the cloth-bag type dedusting is be most widely used a kind of.The cloth-bag type dedusting truly has good effect to the purification of flue gas, but fiber bag precipitator itself also has certain shortcoming: one, cloth bag filtrate quality does not pass a test, and cloth bag is short service life; Two, the secondary pollution of fiber bag precipitator is serious, directly endangers the healthy of operator; Three, the detection difficulty of damaged cloth bag is big, will stop production when changing and keeping in repair, and influences the ordinary production of enterprise.
Summary of the invention
The technical problem to be solved in the present invention is: at the shortcoming of above-mentioned sack cleaner, study a kind of cloth bag that need not, dust removing effects can reach more than 98%, and installation and maintenance are convenient, the flue-gas dust removal and purification device of efficient, energy-saving and environmental protection.
The technical solution adopted for the present invention to solve the technical problems is: this flue-gas dust removal and purification device, it is characterized in that: comprise discharge pipe, retaining mud dividing plate, impeller, smoke chamber, hopper, blast pipe, housing, motor, housing is a ducted body, the bottom is that discharge pipe one side is a blast pipe for hopper top, smoke chamber is contained in the housing and connects blast pipe, impeller is installed in the smoke chamber upper body and with motor and links to each other, retaining mud dividing plate is installed between housing upper end cover and the impeller and with inner walls and closely links to each other, and the housing upper end is provided with the spray atomising device; The effect of retaining mud dividing plate is that dust and the flue gas after being purified that will collect separates.Smoke chamber top is tubular, and the bottom is the round platform or the funnel-form of falling.The effect of smoke chamber is the flue dust of collecting to come in by blast pipe.
The blade of impeller is 3; Satisfy the wind-force requirement.
Uniform small through hole on the blade.The effect of small through hole is that flue dust is caught in absorption, and the resistance that reduces equipment.
The spray atomising device comprises penstocks and atomizer, is arranged between motor and the retaining mud dividing plate.The effect of spray atomising device is to make the quality of soot dust granule become big by atomized water spray, is convenient to impeller and catches and throw away.
Retaining mud dividing plate is a funnel-form.
Dust-cleaning principle
Discharged flue gas such as fire coal, oil burning boiler or kiln at first enter in the blast pipe, enter smoke chamber by intake stack, flue gas moves from bottom to top in smoke chamber, a press water pipeline is arranged at the top at device, water is under certain pressure in the access arrangement, through the atomizer atomizing, water smoke moves from top to bottom.Flue gas upwards and downward water smoke meet at device interior, tiny water droplet combines with dust in flue gas, increased the weight of dust self, many such dust granules flock together, it is big that weight slowly becomes, when running into the impeller of rotation, be thrown on the inwall around the device case and be slipped to along inner walls in the hopper of bottom.Impeller is by the driven by motor that is installed in device top, and like this, dust in flue gas just can effectively be removed, and the flue gas after the dedusting continues upwards to enter discharge pipe and discharges.
Compared with prior art, the beneficial effect that flue-gas dust removal and purification device of the present invention had is: because the impeller by particular design is caught the up flue dust of smoke chamber in housing, flue dust to different flow adopts different motor speeds, can preferably the flue dust of retaining below retaining mud dividing plate be thrown on the inner walls, the housing upper end is provided with spray atomising device one side flue dust dust granules in continuous water spray and flocks together, it is big that weight slowly becomes, when running into the impeller of rotation, be thrown on the housing inwall all around; Also play the purpose that the tiny flue dust that impeller is not captured passes through the further dedusting of spray on the other hand.Therefore, the flue gas of handling through this device can reach or be better than " ambient air quality " (GB3095-1996) discharge standard, makes atmospheric environment obtain good improvement.Use this device smoke treatment, overcome the shortcoming of sack cleaner; Have long service life, non-secondary pollution, it is little to take up room, and is convenient to operation, need not cloth bag, and dust removing effects can reach more than 98%, and installation and maintenance are convenient, advantages such as efficient, energy-saving and environmental protection.Than using sack cleaner to reduce investment, saved operating cost.Can solve problem of environmental pollution, economic benefit and obvious social benefit preferably.
