Abstract
The utility model relates to a flue gas cleaning and dust removing device which comprises cyclone barrels, a central exhaust pipe and a dust collecting bucket, wherein the inner walls of the cyclone barrels are provided with a layer of inner lining, the bottoms of the cyclone barrels are connected with the dust collecting bucket, an air inlet is fixed to the upper parts of the cyclone barrels, the central exhaust pipe and the cyclone barrels are fixed together through a spiral vane, wherein the upper parts of two cyclone barrels can share one air inlet, the lower parts of the cyclone barrels are both connected to one dust collecting bucket, and the cyclone barrels, the air inlet and the dust collecting bucket can be combined into a secondary or multi-stage structure. The dust removing efficiency of the utility model can achieve more than 95% and is from 5% to 10% higher than that of an ordinary cyclone dust remover, and the utility model has the advantages of high-temperature resistance, energy saving and power saving. Due to the adoption of a dry recovery method, dust can be used as raw materials of fire-proofing materials or ordinary construction materials to be secondarily utilized. The device can enhance yield when used on a magnesite vertical kiln, and meanwhile, the device can effectively eliminate workers' carbon monoxide poisoning accidents, and realize the concentrated exhaust of flue gas after dust removal.
Description
Technical field: the utility model relates to the gas cleaning deduster of a kind of magnesia shaft furnace and the use of other kiln.
Background technology: the magnesia shaft furnace in the present magnesia refractories industry, the overwhelming majority does not have cleaner, minority shaft furnace sack cleaner, the one, cloth bag holds high-temperature flue gas effect that can't stand the shaft furnace discharging; The 2nd, there was dampness in the air or dedusting flue-gas temperature dewfall when close dew temperature for the Mgo dust granules chance in the flue gas, reacts with water after magnesia powder dust adheres on the cloth bag, and the magnesium hydroxide of generation is bonded on the cloth bag very firm, and the cloth gas permeability is descended until inefficacy.The electric cleaner non-refractory, the equipment price costliness.And general cyclone dust device inner surface is that common iron is made, and inner surface is smooth, after dust is run into inner surface, tangentially fly up again, can not effectively consume the kinetic energy of dust granules, therefore produce reentrainment of dust, efficiency of dust collection does not reach national specified discharge standard.
Summary of the invention: the purpose of this utility model is the smoke abatement and dust control problem that solves current dead burnt magnesite sand shaft furnace and electric magnesite-smelting furnace, and a kind of efficiency of dust collection height, resistant to elevated temperatures gas cleaning deduster are provided.
For achieving the above object, the technical solution of the utility model is: a kind of gas cleaning deduster, comprise whirlwind tube, central row tracheae, dust hopper, whirlwind tube inwall is provided with one deck liner, the bottom is connected with dust hopper, air inlet is fixed on the top of whirlwind tube, and central row tracheae and whirlwind tube are fixed together by helical blade.Wherein two whirlwind tube top can a shared air inlet, and the bottom all is connected on the dust hopper, and one-tenth secondary capable of being combined or multilevel hierarchy.
The utility model is owing to adopt said structure, two cyclones can be together in series and form secondary, three grades of series connection, because in magnesia shaft furnace and the electric magnesite-smelting furnace discharged flue gas, the main chemical of dust is the Mgo dust granules, wherein thick more than 90%, can collect in one-level bispin wind, the particle dust less than 10% is collected in secondary bispin wind.The utility model is compared with existing common cyclone dust collectors, efficiency of dust collection can reach more than 95%, and efficiency of dust collection exceeds common cyclone dust collectors 5-10%, and high temperature resistant, because adopt dry method to reclaim, raw material or common buildings material that dust can be used as refractory material carry out the secondary utilization.This product is used on the magnesia shaft furnace can improve output, and workman's anthracemia accident can be effectively eliminated in energy-conservation economize on electricity simultaneously, fume centralized discharging after the realization dedusting.
Description of drawings: Fig. 1 revolves structural representation for the utility model list.
Fig. 2 is the utility model bispin structural representation.
Fig. 3 is the vertical view of Fig. 2.
The specific embodiment: the specific embodiment of the present utility model is described further: a kind of gas cleaning deduster below in conjunction with accompanying drawing, comprise whirlwind tube 1, central row tracheae 5, dust hopper 2, whirlwind tube 1 inwall is provided with one deck liner 6, the bottom is connected with dust hopper 2, air inlet 4 is fixed on the top of whirlwind tube 1, central row tracheae 5 tops are gas outlet 3, and central row tracheae 5 is fixed together by helical blade 6 with whirlwind tube 1.Wherein two whirlwind tube top can a shared air inlet 4, and the bottom all is connected on the dust hopper, and one-tenth secondary capable of being combined or multilevel hierarchy.Liner 6 in the whirlwind tube is that a kind of special material is made, and its surface microscopic is uneven, is ripple or pit shape, has effect wear-resisting and the absorption dust.
During the utility model work, ash-laden gas enters from air inlet 4, through helical blade 7, enter in the whirlwind tube 1, owing on whirlwind tube 1 inwall one deck liner 6 is set, dusty gas rotates through certain speed, dust granules is under action of centrifugal force, separate from gas, strike on the liner 6, this moment, grit kinetic energy disappeared, slip in the dust hopper 4 along liner 6, realize existing dust removal process, purified gas converges to gas outlet 3 through central row tracheae 5, and then enters the air-introduced machine discharge.
Claims (2)
1, a kind of gas cleaning deduster, comprise whirlwind tube, central row tracheae, dust hopper, it is characterized in that whirlwind tube inwall is provided with one deck liner, the bottom is connected with dust hopper, air inlet is fixed on the top of whirlwind tube, and central row tracheae and whirlwind tube are fixed together by helical blade.
2, gas cleaning deduster according to claim 1, it is characterized in that can be at two shared air inlets in whirlwind tube top, and the bottom all is connected on the dust hopper, and one-tenth secondary capable of being combined or multilevel hierarchy.
