Description

A kind of metallurgy mixes cooling air unit with rotary hearth furnace high-temperature flue gas
Technical field
The utility model is related to a kind of metallurgical gas to mix wind devices, and in particular to a kind of metallurgy is mixed with rotary hearth furnace high-temperature flue gas Cooling air unit.
Background technology
At present, the method that the flue gas that cooling high-temperature fume uses in metallurgy industry mixes cold wind is simple and practicable.But in reality Border results in the need for longer mixation tube section just in use, because cool exterior air channel connects the unreasonable of setting with exhaust gases passes It can make the uniform reduction of temperature of the high-temperature flue gas in exhaust gases passes, the arrangement space distance of equipment room is caused to increase, is occupied more More places.
Therefore, it is necessary to a kind of new technical solutions to solve above-mentioned technical problem.
Utility model content
To solve the deficiencies in the prior art, the purpose of this utility model is that proposing a kind of by cool exterior air and high temperature cigarette The metallurgy that gas is quick, uniformly mixes mixes cooling air unit with rotary hearth furnace high-temperature flue gas.
In order to realize above-mentioned target, the utility model adopts the following technical scheme:A kind of metallurgical rotary hearth furnace high temperature cigarette Gas mixes cooling air unit, which includes cool exterior air pipeline, equalizing warehouse, flue, the end of the cool exterior air pipeline End is connected to form venting channels with equalizing warehouse, and the equalizing warehouse is sheathed on the outside of the tube wall of the flue, the flue gas The tube wall of pipeline is equipped with air flow method hole, and the equalizing warehouse is connected by the air flow method hole with the flue.
Preferably, the end of the cool exterior air pipeline is the port of export, and the port of export is connected with equalizing warehouse.
Preferably, the arrival end of the cool exterior air pipeline is equipped with steel wire, effectively prevent the sucking of foreign matter.
Preferably, the sectional area of the equalizing warehouse should be greater than the sectional area of the cool exterior air pipeline.Utilize equalizing warehouse The reduction of air velocity and the promotion of static pressure are realized in the increase of sectional area.
Preferably, the cool exterior air pipeline is internally provided with electric control valve, can according to required flue-gas temperature The size of electric control valve is adjusted, so as to adjust the speed that extraneous air enters the equalizing warehouse.
Preferably, the middle part of the cool exterior air pipeline is equipped with electric control valve.
Preferably, the even tube wall of the flue is equipped with air flow method hole.
Compared with the prior art, the utility model is beneficial in that:The metallurgy mixes cold wind with rotary hearth furnace high-temperature flue gas Device by external air duct, the setting of equalizing warehouse, flue, realize cool exterior air and high-temperature flue gas it is quick, Uniform mixing, while flue-gas temperature is reduced, effectively shortens the uneven length of smoke mixing section, facilitates equipment Arrangement in a limited space.
Description of the drawings
Fig. 1 is the schematic diagram that the utility model metallurgy mixes cooling air unit with rotary hearth furnace high-temperature flue gas.
Specific embodiment
Make specific introduce to the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of metallurgy mixes cooling air unit with rotary hearth furnace high-temperature flue gas, which includes cool exterior air pipeline 1, equalizing warehouse 2, flue 3, end and the equalizing warehouse 2 of cool exterior air pipeline 1 are connected to form venting channels, 2 sets of equalizing warehouse Set on the outside of the tube wall of flue 3, the tube wall of flue 3 is equipped with air flow method hole 4, and equalizing warehouse 2 passes through air flow method Hole 4 is connected with flue 3.
Wherein, the end of cool exterior air pipeline 1 is the port of export, and the port of export is connected with equalizing warehouse 2.Cool exterior air pipeline Arrival end be equipped with steel wire 5, effectively prevent the sucking of foreign matter.
The sectional area of equalizing warehouse 2 should be greater than the sectional area of cool exterior air pipeline 1.Air-flow is realized using the increase of sectional area The reduction of speed and the promotion of static pressure.
Cool exterior air pipeline 1 is internally provided with electric control valve 6, it is preferable that electric control valve 6 is arranged on external cold sky The middle part of feed channel 1.Can according to required flue-gas temperature adjust electric control valve 6 size, so as to adjust extraneous air into Enter the speed of equalizing warehouse 2.
Cool exterior air pipeline 1, equalizing warehouse 2,3 three of flue are connected by air flow method hole 4;High-temperature flue gas passes through During exhaust gases passes 3, under the adjusting of electric control valve 6, cool exterior air can be rapidly entered by cool exterior air pipeline 1 Storehouse 2 is pressed, is reduced in 2 interior air-flow speed of equalizing warehouse, static pressure increase, then by equally distributed in 3 wall surface surrounding of flue Air flow method hole 4 is rapidly and uniformly mixed with high-temperature flue gas.It realizes cool exterior air and the quick, uniform of high-temperature flue gas mixes It closes, while flue-gas temperature is reduced, effectively shortens the uneven length of smoke mixing section.
The basic principle, main feature and advantage of the utility model has been shown and described above.The technical staff of the industry It should be appreciated that examples detailed above does not limit the utility model, all institutes by the way of equivalent substitution or equivalent transformation in any form The technical solution of acquisition, all falls in the scope of protection of the utility model.
