Description
Technical field
The utility model relates to a kind of tubular type steam water heat exchanger, belongs to steelmaking converter high-temperature flue gas dry method dust and process waste heat returns apparatus field.
Background technology
Steel-making flue gas processing method traditional at present has OG method and LT method.The flow process of OG method is that converter gas is after overskirt, I to IV section of gasification cooling flue cooling, about 800 DEG C are down to by 1600 DEG C, then a literary composition, the cooling also dedusting further of two literary compositions is entered, centrifugal blower is drawn to three-way switch valve again through luring, qualified coal gas sends into gas recovery cabinet, does not reach the flue gas reclaiming requirement and enters diffusing tower igniting discharge.There is following defect in it:
1), the dedusting water yield of a literary composition, two literary composition needs is very large; 2), steam and wet dust be bonded to Vanes on Induced Draft Fan, and cause rotor unbalance, cause blower fan to shake and damage, fault rate is high, and influential system normal table runs; 3), the easy fouling of system, cause dust collection capacity to decline, dust collecting effect and clean-up effect are deteriorated, and fire door flue dust is excessive, diffusing tower emits tobacco; 4), SR is large, and power consumption is high; 5), sewage, sludge treating process be complicated, and floor space is large, and easily causes secondary pollution; 6) affect by Venturi tube efficiency, smoke dust discharge concentration higher (for 50-100mg/Nm3).
The representational flow process being devaporizer and adding electrostatic precipitator of LT dry method dust most, Thyssen Aktiengesellschaft strange by West Germany Shandong combines release, is called for short LT method.Technological process is: flue gas enters after gasification cooling flue cools indirectly, more directly carry out with devaporizer cooling-spray into atomized water to by the flue gas in devaporizer.The water yield sprayed into, will determine with the heat content producing thermal current in steelmaking process exactly, after flue gas being cooled to 150 DEG C one 200 DEG C, introducing electrostatic precipitator carry out smart dedusting via gas piping.Then by air inducing equipment--axial blower enters coal gas switching station, and qualified coal gas enters recovery system after cooling further, and underproof coal gas is through diffusing tower ignition bleeding.The shortcoming of this dry method dust.1) high, the automatic control of dry method dust cost is chain many, requires that automaticity is high; 2) plant equipment adopted is many, complex structure, and fault rate is high, and maintenance time is long; 3) because evaporative cooling makes to contain higher moisture in coal gas, easily form condensation, affect anode-cathode distance and working voltage, affect ash-transmission system equipment service life simultaneously, for this has strict demand to the wet cooling tower water yield, hydraulic pressure control; 4) on evaporative cooling wall, scale problems does not also well solve; 5) require high to converter operation, deduster, can sacrifice steel-making rhythm, otherwise explosive, although there is explosion venting device, still can affect life-span and the dust removing effects of parts in electric cleaner; 6) after dedusting, gas temperature is high, just can enter gas chamber after special cooling device also must be adopted to cool, herein water consumption and wet dedusting periodical feeding amount close.All do not have structure simple in the said equipment, can segmentation heat exchange and high efficiency heat transmission equipment.
