Description
Technical field
The present invention relates to a kind of powder medicine chemicals dosing plant, particularly a kind of chemicals dosing plant adding powder medicine in flue gas, belongs to field of metallurgical equipment.
Background technology
Copper making and other waste heats thermal technology boiler are that a kind of utilization smelts the heat transmission equipment that the waste heat produced in production is converted into steam.Energy transferring, by releasing chemical energy in waste heat, is fed water by diabatic process by it, makes water be transformed into steam, and steam directly supplies the various forms of energy required in industrial production.
In Copper making and other smelting processes, because the constituent contents such as lead, zinc in concentrate are high, and the fluctuation of metallurgical furnace flue gas amount is larger.SO
2easily there is slagging scorification with the high positions such as the uptake flue of waste heat thermal technology boiler, water-cooled baffle, crust block pipe that cause of the content of flue dust, thus cause residual heat boiler for exchanging heat effect to decline, derive from the significant troubles such as Pipe Bursts in Waste Heat Boilers further and occur.The control of boiler scaling is one of bottleneck and a difficult problem that in Copper making, waste heat boiler runs, at present, the control of waste heat boiler slagging scorification is mainly realized by rapping equipment and salt wind transmission, and the processing method of waste heat boiler slagging scorification concentrates in the means such as design, interpolation powder medicine of labor cleaning, blasting procedure, change uptake flue.Wherein adopt the successful case of powder medicine process Copper making and other waste heats thermal technology boiler few, reason is all adopt disposablely to pour method into, weak effect.
Summary of the invention
The object of the invention is based on problems of the prior art, provide a kind of powder medicine chemicals dosing plant, this device prevents the position slagging scorification such as thermal technology's boiler uptake flue, water-cooled baffle, crust block pipe.
The technical solution realizing the object of the invention is: a kind of powder medicine chemicals dosing plant, comprise the feed hopper set gradually, mechanical conveying equipment, intermediate bin, emission cavity and emission cavity pipeline from top to bottom, feed hopper is arranged on above mechanical conveying equipment one end, intermediate bin is arranged on below the mechanical conveying equipment other end, the discharging opening of intermediate bin is connected with the charging aperture of emission cavity, the feed opening of emission cavity and the junction of emission cavity pipeline are semi-closed state, fluidic generator is placed in emission cavity pipeline, and its nozzle is positioned at the below of semiclosed opening; The diameter of intermediate bin discharging opening and emission cavity charging aperture is 40-60mm, and the diameter of emission cavity discharging opening is 40-50mm.
The nozzle retractable of described fluidic generator, its both sides, end have arc opening, and nozzle diameter is 8-10mm.
In described feed hopper, screw feeder is set.
Described emission cavity, intermediate bin are infundibulate.
Described mechanical conveying equipment comprises motor and conveyer belt.
The preferred 50mm of diameter of described emission cavity charging aperture, the preferred 45mm of diameter of emission cavity discharging opening.
Principle of the present invention is: utilize malleation conveying principle, initial with end stage time, feeding coal be less than jet entrainment band momentum time, powder jet entrainment drive under, spray in body of heater flue.Feeding coal be greater than jet entrainment band momentum time, material can be assembled in conveyor chamber, when gathering a certain amount of, gases at high pressure formed malleation conveying promote agglomerates enter body of heater.
The present invention compared with prior art, by this device Segmented timed, quantifying feed, enable medicament more fully with the slag hybrid reaction in flue gas, make thermal technology's boiler water-cooling baffle plate, the character of crust block pipe place's slagging scorification become fragile, can self falling.Decrease because of thermal technology's boiler water-cooling baffle plate, the place's slagging scorification of crust block pipe on the impact of producing, the effect of economic technology is huge.
Accompanying drawing explanation
