Abstract
The invention discloses a feeding device for a powder reagent. The feeding device for the powder reagent comprises a feeding bin, a mechanical conveying device, an intermediate bin, a jetting cavity and a jetting pipeline, wherein the feeding bin, the mechanical conveying device, the intermediate bin, the jetting cavity and the jetting pipeline are arranged in sequence from top to bottom. The feeding bin is arranged above one end of the mechanical conveying device. The intermediate bin is arranged below the other end of the mechanical conveying device. A discharging port of the intermediate bin is connected with a feeding port of the jetting cavity. The position wherein a discharging port of the jetting cavity is connected with the jetting cavity pipeline is in the half-closed state. A fluidic generator is arranged in the jetting cavity pipeline. A jetting nozzle of the fluidic generator is located below the half-closed port. The diameter of the discharging port of the intermediate bin, namely the feeding port of the jetting cavity is 40-60mm. The diameter of the discharging port of the jetting cavity is 40-50mm. By the adoption of the feeding device for the powder reagent, sectional timing and quantitative feeding are achieved, so that the reagent is mixed with and reacts with slag in smoke more completely, the slag in the positions of a water cooling baffle and a slag screen of a thermal engineering boiler is embrittled and can fall off automatically, the influence of the slag in the positions of the water cooling baffle and the slag screen of the thermal engineering boiler on the production is reduced, and the effect of economic technology is large.
Description
Technical field
The present invention relates to a kind of powder medicine chemicals dosing plant, particularly a kind of chemicals dosing plant to adding powder medicine in flue gas, belongs to field of metallurgical equipment.
Background technology
Copper is smelted and other waste heats thermal technology boiler is that a kind of utilization smelted the heat transmission equipment that the waste heat producing in production is converted into steam.It,, by emitting chemical energy in waste heat, feeds water energy transmission by diabatic process, makes water be transformed into steam, and steam is directly supplied with the various forms of energy required in industrial production.
In copper smelting 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 position such as the high uptake flue that causes waste heat thermal technology boiler of the content of flue dust, water-cooled baffle, crust block pipe, thereby cause residual heat boiler for exchanging heat effect to decline, further derive from the significant troubles such as Pipe Bursts in Waste Heat Boilers and occur.The control of boiler scaling is one of the bottleneck of waste heat boiler operation during copper is smelted and difficult problem, at present, the control of waste heat boiler slagging scorification is mainly to realize by rapping equipment and salt wind transmission, and the processing method of waste heat boiler slagging scorification concentrate on labor cleaning, blasting procedure, change uptake flue design, add in the means such as powder medicine.Wherein adopt the successful case of powder medicine processing copper smelting and other waste heats thermal technology boiler few, reason is all to adopt the disposable method of pouring into, weak effect.
Summary of the invention
The object of the invention is based on problems of the prior art, a kind of powder medicine chemicals dosing plant is provided, this device has prevented the position slagging scorification such as thermal technology's boiler uptake flue, water-cooled baffle, crust block pipe.
The technical solution that realizes the object of the invention is: a kind of powder medicine chemicals dosing plant, comprise the feed hopper setting gradually, mechanical conveying equipment, intermediate bin, emission cavity and emission cavity pipeline from top to bottom, feed hopper is arranged on top, mechanical conveying equipment one end, intermediate bin is arranged on mechanical conveying equipment other end below, the discharging opening of intermediate bin is connected with the charging aperture of emission cavity, the junction of the feed opening of emission cavity and emission cavity pipeline is semi-closed state, fluidic generator is placed in emission cavity pipeline, and its nozzle is positioned at the below of semiclosed opening; Intermediate bin discharging opening is that the diameter of emission cavity charging aperture is 40-60mm, and the diameter of emission cavity discharging opening is 40-50mm.
The nozzle of described fluidic generator is scalable, and 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, when initial and end stage, feeding coal is less than entrainmenting while being with momentum of jet, and powder entrainments under drive jet, sprays in body of heater flue.What feeding coal was greater than jet entrainmenting band during momentum, and material can be assembled in conveyor chamber, and when gathering when a certain amount of, gases at high pressure form malleation and carry and promote agglomerates and enter body of heater.
The present invention compared with prior art, by this device Segmented timed, quantifying feed, make medicament can be more fully with flue gas in slag hybrid reaction, the character of thermal technology's boiler water-cooling baffle plate, the place's slagging scorification of crust block pipe is become fragile, can self falling.Reduced because of thermal technology's boiler water-cooling baffle plate, the impact of crust block pipe place's slagging scorification on production, the effect of economic technology is huge.
Accompanying drawing explanation
Fig. 1 is the last drug dosing device equipment schematic diagram of invention.
Fig. 2 is emission cavity pipe interior structural representation of the present invention.
The specific embodiment
In Fig. 1-2, a kind of powder medicine chemicals dosing plant, comprise the feed hopper 1, mechanical conveying equipment 2, intermediate bin 3, emission cavity 4 and the emission cavity pipeline 5 that set gradually from top to bottom, feed hopper 1 is arranged on mechanical conveying equipment 2 tops, one end, the interior screw feeder that arranges of feed hopper 1; Intermediate bin 3 is arranged on mechanical conveying equipment 2 other end belows, and intermediate bin 3 is shaped as infundibulate; Machinery conveying equipment 2 comprises motor and conveyer belt; The discharging opening of intermediate bin 3 is connected with the charging aperture of emission cavity 4, emission cavity 4 is shaped as infundibulate, the junction of the feed opening of emission cavity 4 and emission cavity pipeline 5 is semiclosed opening (being that semiclosed opening is for semicircle), fluidic generator 6 is placed in emission cavity pipeline 5, its nozzle 7 is scalable, nozzle 7 is positioned at the below of semiclosed opening, and nozzle 7 both sides, end have arc opening, and diameter is 8-10mm; Intermediate bin 3 discharging openings are that the diameter of emission cavity 4 charging apertures is 50mm, and the diameter of emission cavity 4 discharging openings is 45mm, and experimental result shows, the diameter proportion of charging aperture and discharging opening will arrange rationally, and diameter is excessive, can cause that powder is excessive, diameter is too small, can cause powder blanking obstacle.
