Abstract
An apparatus for reducing smoke and dust of glass crucible furnace is installed outside the furnace. Its blower is connected via main blast pipe to draft distributing box, which is connected via branch pipes with lower pipes inserted into lower craters. The number of branch pipes or lower pipes is equal to the number of lower craters or crucibles. The air from blower goes through mainb last pipe, droft distributing box, branch pipes and lower pipes, then is mixed with fume of lower craters, and finally takes part in combustion for full burning. Its advantages are simple structure and high effect.
Description
The present invention relates to a kind of device for eliminating smoke and dust of glass pot kiln.
The existing coal-burning glass pot furnace of China comprises the kiln body, air channel and quirk are housed in the kiln body, on kiln body top stone or metal plate for standing a stove on as a precaution against fire is arranged, the truncated cone-shaped heating clamber is arranged on the stone or metal plate for standing a stove on as a precaution against fire, be provided with crucible around the heating clamber, the outer side-lower of truncated cone-shaped heating clamber is provided with down burner, the pyrotechnics of this pot furnace sprays into heating clamber from the flame tube, crucible is heated, useless then flue gas enters flue through following burner and discharges from chimney, because this special construction and special technology cause serious smoke contamination, do not have a kind of effective improvement technology so far.The inventor has applied for that October nineteen ninety-five name is called ＂ energy-saving free of smoke dust pollution pot furnace ＂ utility model patent, application number is 95232394.x, it is the structure of original kiln to be transformed promptly be provided with the deep bead that is used to control the air inlet size at secondary air mouth place, on circular air channel, be provided with the multilayer wind isolation board from bottom to up, be provided with 5～7 layers of air vent at last jet-burner, 8～10 every layer, aperture 10～50mm, high 70～100mm, air vent is facing to angled moving rising of conch rotation that makes ejection of bocca, pyrotechnics upwards sprays from last burner, the wind that sprays into from the multilayer air vent is tangent with the pyrotechnics rotation on aspect horizontal, fully mixes fully burning and forms smokeless flames, reaches dust-laying effect again thereby eliminate black smoke, but it only is applicable to new block kiln, is not suitable for the transformation to original glass pot kiln.
The device for eliminating smoke and dust that the purpose of this invention is to provide a kind of glass pot kiln.This device also is applicable to existing various glass pot kilns other kiln such as furnace identical with working condition, and the refractory material kiln is installed and used.
The present invention is achieved in that it is to lay lower air conduit at the following jet-burner of pot furnace, and bubbling air makes air mix with the pyrotechnics of following burner and participates in burning, reaches the purpose that oke exhaust blackness and depositing dust are eliminated in abundant burning.It can be equipped with blower fan 9 in suitable place outside existing glass pot kiln, blower fan 9 is connected with draught distributing box 7 on being installed in kiln lid 12 by blast main 8, draught distributing box is told branch wind pipe 10 and is connected with lower air conduit 6, lower air conduit 6 inserts in the following burner 5, the wind plate 11 that is used to regulate intake is installed on blast main 8, according to the coal amount what, decide wind plate breakdown size.Like this, the air by blower fan 9 is blown into enters draught distributing box 7 by blast main 8, by draught distributing box process branch wind pipe 10, enters lower air conduit 6 again, and in the burner 5, the air that enters lower air conduit mixed the participation burning with the flue gas of following burner under lower air conduit inserted; Can also a little blower fan be installed in each lower air conduit 6 upper end, burner 5 is down inserted in the lower end, directly wind is blown in the kiln, mixes participating in burning with flue gas, reaches the purpose of smoke abatement and dust control.
Advantage of the present invention is:
1. reduction smoke contamination, graceful 0.2～0.5 grade of its blackness of exhaustion Green, dust-exhausting quantity is at 30～60mg/Nm
3Be lower than national specified discharge standard, obvious environment benefit;
2. the raising exhaust gas temperature improves preheat temperature to the secondary wind in the flame tube, helps improving the heating clamber temperature, thereby boosts productivity;
3. applicability is strong, is applicable to other kiln that various glass pot kilns are similar with working condition, and as furnace, the refractory material kiln uses;
4. easy to operate, flexibly;
5. simple in structure, easy for installation, can overhaul dismounting at any time.
Description of drawings:
Fig. 1 is this device for eliminating smoke and dust front view;
Fig. 2 is a B-B cutaway view among Fig. 1.
Embodiment 1
On kiln lid 12, draught distributing box 7 is set, draught distributing box 7 upper ends are connected by blast main 8 blower fan 9 external with being located at kiln the wind plate 11 of regulating air quantity are housed on blast main 8, draught distributing box 7 lower ends are connected with branch wind pipe 10, branch wind pipe is connected with lower air conduit 6, and this device for eliminating smoke and dust is located at outside the kiln and enters in the kiln by burner 5 under lower air conduit 6 insertions; The quantity of branch wind pipe 10, lower air conduit 6 is consistent with the quantity of following burner and crucible, flue gas sprays into from the flame tube 3 of kiln body 4 and enters down burner 5 in the heating clamber 1 again and mixes with lower air conduit 6 ejection air and participate in burning, thereby flue gas is fully burnt, reach the purpose of eliminating black smoke and depositing dust.
Embodiment 2
In each lower air conduit 6 upper end a little blower fan is installed, burner 5 is down inserted in the lower end, directly wind is blown in the kiln to mix the participation burning with flue gas, reaches the purpose of abundant burning smoke dedusting.
