Abstract
The utility model discloses a gas purification tower, belonging to the field of dust removal equipment for blast furnaces. The gas purification tower comprises a scrubbing tower, an inlet pipe, a nozzle, a guide pipe, a water seal drainer and a water droplet capture layer. The inlet pipe is communicated with the guide pipe and stretches into the purification tower; the water droplet capture layer is arranged above an orifice outside the guide pipe; the nozzle is arranged above an inner chamber of the guide pipe; the water seal drainer is arranged at the lower part of the purification tower; and an outlet pipe is arranged at the upper part of the scrubbing tower. The gas purification tower, by using the nature of chloride ions soluble in water, is used for carrying out water-spray type scrubbing on the blast furnace gas to remove a majority of chloride ions in the blast furnace gas, thereby preventing the corrosion of chloride ions to gas pipes and accessories. Water consumption is less due to the water-spray type; and the washing water containing chloride ions is easy for concentrated discharge and treatment. The gas purification tower has the advantages of high efficiency, simple structure and convenience maintenance, and can prolong the service lives of gas pipes and accessories safely and reliably.
Description
Technical field
The utility model is applied to the dry-dedusting system of blast furnace gas in the ferrous metallurgy associated enterprises, belongs to the blast furnace dedusting apparatus field.
Background technology
Gas purification tower is used for purifying the contained chlorion of blast furnace gas, to avoid the corrosion of chlorion to gas line and annex generation, makes pipe network operation safer.At present, from the by-product gas that blast furnace ironmaking produces, all contain chlorion mostly.Saturated vapor in the blast furnace gas is separated out gradually along with the reduction of gas temperature, then chlorion soluble in water in, therefore, chloride ion content in the blast furnace gas condensate water is higher, its solution value is stronger acidity, so gas line and annex are caused heavy corrosion, corrosion location generally concentrates on positions such as the bottom, pipe welding seam, pipeline compensator, row of conduits hydrophone of pipeline, its corrosion speed is very fast, has destroyed the safe and stable operation of blast furnace gas pipeline network.
Current, enterprise is the corrosion of the chlorion in the solution blast furnace gas condensate water to gas line and annex generation, taked the coating of the anti-chloride ion corrosion of blast furnace gas pipeline internal spray and pipeline compensator to take to select for use the material etc. of resisting corrosion of chlorine ion, because protective system should come off and the fund input of the material of the corrugated tube of pipeline compensator employing 254 or 825 is bigger, it is undesirable then to produce effects.
The utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of gas purification tower, and it adopts spray pattern to be washed, the most of chlorion that removes in the blast furnace gas to be contained, and the prevention chlorion is to the corrosion of gas line and annex.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of gas purification tower, comprises clean tower, it is characterized in that, it also comprises inlet pipeline, nozzle, thrust-augmenting nozzle, water seal hydathode and water droplet trapping layer; This inlet pipeline and thrust-augmenting nozzle connect and are connected and stretch to described clean tower inside; Be provided with the water droplet trapping layer above the mouth of pipe outside described thrust-augmenting nozzle; Above the refluence tube cavity, be provided with described nozzle; Be provided with the water seal hydathode in the bottom of described clean tower; Be provided with outlet conduit on the top of cleaning tower.
Further, described nozzle setting is provided with more than one and by layer and arranges.
Further, described thrust-augmenting nozzle is tubaeform.
The technique effect that the utility model reaches is as follows: the utility model gas purification tower, be the character of utilizing chlorion water-soluble, blast furnace gas is carried out the washing of water spray formula, remove most of chlorion contained in the blast furnace gas, reach the corrosion that prevents that chlorion from producing gas line and annex.And, adopting the water spray mode, water consumption is few; The washing water of chloride ion-containing are easy to concentrate to be discharged and handles; The efficient height, simple in structure, easy to maintenance.Have work-ing life safe, reliable, that prolong gas line and annex, be widely used in the treating plant of smelter blast furnace gas dry dusting system.

Embodiment
As shown in Figure 1, be the utility model gas purification tower, comprise and clean tower 6, inlet pipeline 1, nozzle 2, thrust-augmenting nozzle 3, water seal hydathode 5 and water droplet trapping layer 4.This inlet pipeline 1 connects to be connected and to stretch to thrust-augmenting nozzle 3 cleans tower 6 inside, and thrust-augmenting nozzle 3 can be tubaeform.Above the mouth of pipe in thrust-augmenting nozzle 3 outsides, be provided with water droplet trapping layer 4; Be provided with nozzle 2 above pipe 3 inner chambers that flow backwards, nozzle 2 can be provided with a plurality of, and can be according to multilayer arrangement from top to bottom.Be provided with the water seal hydathode 5 of connection in the bottom of cleaning tower 6, be provided with outlet conduit 7 on the top of cleaning tower 6.
During work, come to enter in the thrust-augmenting nozzle 3 of cleaning tower 6 by inlet pipeline 1 to the blast furnace gas of bag-type dust, the water spray multilayer nozzle 2 that above the thrust-augmenting nozzle 3 of cleaning tower 3, is provided with, its spray water is taken away chlorion in the coal gas, and the water that contains chlorion is discharged from the water seal hydathode 5 of cleaning tower 6 bottoms.And coal gas through thrust-augmenting nozzle 3 enter water droplet trapping layer 4 deviate from machinery moisture after, draw by the outlet conduit 7 of cleaning tower 6.
Gas purification tower of the present utility model is used for blast furnace gas bag-type dust removing system.The water spray of its use can prepare spray water with being added with NaOH alkali lye, the outlet pipe that NaOH alkali lye prepares alkali lye volume pump in the sprinkling system is connected with softening water pump discharge pipe in the softening water assistance sprinkling system, alkali lye after the pressurization is got in the softening water after the pressurization, spray at alkali lye and the shared shower nozzle of softening water place, in the nozzle of cleaning in the tower 62, spray by pipe-line transportation.The stronger chlorion of corrodibility in the energy effective elimination coal gas, the pH value of raising coal gas condensed water.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
