Abstract

The utility model relates to a smoke-eliminating and dust-removing device for a glass pot furnace, and the blower of the utility model is connected with a draft distributing box through a blast main. A branch air pipe is arranged on the draft distributing box and is connected with a lower air pipe. The lower air pipe is inserted into a lower crater. The quantity of the branch air pipe and the lower air pipe is the same as the quantity of the lower crater and the pot. The air insufflated by the blower enters the draft distributing box through the blast main, then enters the lower air pipe through the branch air pipe, and then is ejected from the lower crater to mix with the flue gas for combustion. Then the purposes of full combustion, elimination of dark degree of the smoke exhaust, and dust removal are achieved. The utility model has the advantages of simple structure and easy installation and disassembly. The utility model is suitable for various glass pot furnaces and other furnaces with similar condition.

Description

The device for eliminating smoke and dust of glass pot kiln

The utility model 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 purpose of this utility model provides a kind of device for eliminating smoke and dust of glass pot kiln, it is to lay lower air conduit at following jet-burner, bubbling air, air is mixed with the flue gas of following burner participate in burning, reach abundant burning and eliminate the purpose of oke exhaust blackness and depositing dust, it is applicable to that the refractory material kiln is installed and used to existing various glass pot kilns other kiln such as furnace identical with working condition.

The utility model is achieved in that suitable place is equipped with blower fan 9 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 coal what, decide wind plate breakdown size.Like this, the air that is blown into by blower fan 9, enter draught distributing box 7 by blast main 8, again by draught distributing box process branch wind pipe 10, enter lower air conduit 6, 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, reach abundant burning, eliminate the purpose of oke exhaust blackness and depositing dust.

The utility model has the advantages that:

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.

Below in conjunction with accompanying drawing, structure of the present utility model and enforcement are described further:

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, 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, branch wind pipe 10, the quantity of 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.
