At present, the tunnel cave of domestic production foamed ceramics all adopts natural gas as thermal source supply, because foamed ceramics is using polyurethane sponge as carrier, there is following defect in calcination process:
(1) sponge carrier produces pernicious gas in calcination process, and directly discharge in atmosphere, causes air pollution;
(2) portion gas is after the cooling of kiln furnace wall, be adsorbed in tunnel cave, kiln road is caused to block, cause overturning phenomenon, Main carried out stopping production every 1 ~ 2 month thoroughly clearing up tunnel cave, and each cleaning spended time needs about one week, and need to lower the temperature to tunnel cave before each cleaning, need again when reusing to carry out preheating, significantly increase production cost like this, and affect production capacity.
(3) portion gas is adsorbed on product surface, and in temperature-fall period, produce coal tar cover on product surface, cause product percent of pass low, product quality is uneven.
Summary of the invention
the purpose of this utility model just in order to solve above-mentioned oneself have technology Problems existing and provide a kind of for foamed ceramics tunnel kiln kiln gas purifier, thus effectively can reduce pernicious gas and directly discharge and cause environmental pollution, also improve product quality, reduce production cost.
The purpose of this utility model is realized by following technical proposal:
A kind of smoke eliminator for foamed ceramics tunnel cave kiln, it is by combustion furnace 5, blower fan 8, filter chamber 10 and Residual oil preparing device 16 form, described combustion furnace is connected with blower fan and is arranged in gripper shoe 6, gripper shoe is fixed on combustion furnace bracing frame 7, the air inlet pipe 4 of combustion furnace and the blast pipe 3 of kiln body 1 both sides communicate with the straight tube of Residual oil preparing device, the exhaust uptake 2 of the external side of kiln is communicated with the blast pipe of kiln body both sides, the blast pipe 9 of combustion furnace is connected with filter chamber, the ramp type pipeline of the front end of described filter chamber is straight tube middle-end to be downward-sloping straight tube rear end be straight tube composition, front end, filter chamber is communicated with the blast pipe of combustion furnace, the downward-sloping straight tube end of middle-end is built with solid particulate filters net 12, straight tube end, rear end has spiral shell to twist the pipeline cleaning cover cap 15 connected, filter the connection purification heat pipe 14 stopping up the back lower place, scum pipe 11 is arranged on below filter chamber, by support I 13 filter chamber be connected with kiln body and fix, described Residual oil preparing device is by Residual oil collecting pipe 17, cool cycles pipe 18 and heat collector 20 form, the ramp type pipeline of the front end of Residual oil preparing device is straight tube middle-end to be downward-sloping straight tube rear end be straight tube composition, the front end of Residual oil preparing device is stretched into kiln top and is communicated with the blast pipe of kiln body both sides and the air inlet pipe of combustion furnace, pipeline afterbody is fixed on kiln body by support II 19, Residual oil collecting pipe is housed bottom the straight tube of front end, bottom the straight tube of rear end, heat collector is housed, cool cycles pipe is arranged on the pipeline outer-layer of Residual oil preparing device, the sleeve pipe of interior logical cooling water.
Owing to taking technique scheme, make the utility model compared with the prior art tool have the following advantages and effect:
A () this purifier can make the tar entered in air reduce by more than 90%, purified the quality of air, had the feature of environmental protection;
B () have employed the pipeline of ramp type, most of solid in flue gas is directly dropped in pipeline due to Action of Gravity Field, the tar produced in pipeline in addition flow back into its bottom together, body is discharged again by Residual oil collecting pipe, thus tar and adsorbing powder dust can be greatly reduced on product, make product appearance Quality advance more than 90%;
C () makes to enter flue gas in kiln body through again burning and filtering, make the dust in gas reduce by more than 95%, tar content reduces by 100%, greatly reduce the blocking of kiln road risk;
D () increases production capacity, reduce production cost: the cleaning frequency of tunnel cave was cleared up once by 1 ~ February before, is reduced to cleaning in 18 ~ 20 months once;
E () makes to burn a rear heat part and reenters kiln body and reuse, another part uses as life thermal source.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is the side view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model technology is further illustrated:
A kind of smoke eliminator for foamed ceramics tunnel cave kiln, by Fig. 1, shown in Fig. 2, it is by combustion furnace 5, blower fan 8, filter chamber 10 and Residual oil preparing device 16 form, described combustion furnace is connected with blower fan and is arranged in gripper shoe 6, gripper shoe is fixed on combustion furnace bracing frame 7, the air inlet pipe 4 of combustion furnace and the blast pipe 3 of kiln body 1 both sides communicate with the straight tube of Residual oil preparing device, the exhaust uptake 2 of the external side of kiln is communicated with the blast pipe of kiln body both sides, the blast pipe 9 of combustion furnace is connected with filter chamber, tar in the gas that the combustion furnace that kiln installs additional can go out Kiln fire grate and the polyurethane dust do not burnt completely burn again, the tar entered in air is fully burned, thus completely eliminate the tar entered in air, and the solid particle in air is through filter screen filtration, thus purified the gas be discharged in air greatly, the ramp type pipeline of the front end of described filter chamber is straight tube middle-end to be downward-sloping straight tube rear end be straight tube composition, this ramp type pipeline makes the most of solid in flue gas directly drop in pipeline due to Action of Gravity Field, the tar produced in pipeline in addition flow back into its bottom together, discharged by Residual oil collecting pipe again, thus tar and adsorbing powder dust can be greatly reduced on product, make product appearance Quality advance more than 90%, filter the connection purification heat pipe 14 stopping up the back lower place, scum pipe 11 is arranged on below filter chamber, by support I 13 filter chamber be connected with kiln body and fix, purification heat pipe can be returned as kiln body provides heat, described Residual oil preparing device is by Residual oil collecting pipe 17, cool cycles pipe 18 and heat collector 20 form, heat collector can be life and provides heat, the ramp type pipeline of the front end of Residual oil preparing device is straight tube middle-end to be downward-sloping straight tube rear end be straight tube composition, the front end of Residual oil preparing device is stretched into kiln top and is communicated with the blast pipe of kiln body both sides and the air inlet pipe of combustion furnace, pipeline afterbody is fixed on kiln body by support II 19, Residual oil collecting pipe is housed bottom the straight tube of front end, bottom the straight tube of rear end, heat collector is housed, cool cycles pipe is arranged on the pipeline outer-layer of Residual oil preparing device, the sleeve pipe of interior logical cooling water, cool cycles pipe makes gas through supercooling, produce tar, under gravity, flow back into duct bottom, discharged outside by Residual oil collecting pipe, greatly purify the air entering into kiln body, reduce the tar gas in air, decrease kiln body sidewall tar adsorption probability, reduce the possibility of kiln road blocking, improve product quality simultaneously.
In a word the utility model technology according to foam carrier in calcination process produce gas, form liquid state through supercooling, collected by Residual oil collecting pipe again, thus make the hot-air reentering kiln play catharsis, and the gas entered in air again burns through combustion furnace and filters, thus the fuel gas and dust content that can make to enter in air and tar content are reduced greatly.
