Description
Technical field
The utility model relates to a kind of heat accumulation type off-gas incinerator.
Background technology
Current filter paper coating line flow process is as follows: move back paper, coating, oven drying, rolling.In filter paper coating, Main Ingredients and Appearance is methyl alcohol and resin, paper web is through oven drying, and methyl alcohol volatilization is run away, mix waste gas (methanol concentration is about 16%), enter combustion furnace (RTO) through return air duct, return fan etc. to burn, then enter chimney discharge through heat exchanger.Fresh air forms hot blast through heat exchanger and gets back to drying box through hot air duct more simultaneously, carries out paper web drying, circulates and so forth.When break down disconnected paper time, combustion furnace (RTO) autostop, return fan still works, and is discharged in air by residual methanol waste gas in baking oven.In this process waste gas, methanol concentration reduces gradually, until be reduced to the concentration that combustion furnace (RTO) lights a fire again, in order to the ignition security of combustion furnace, this exhaust gas concentration must drop to normal concentration, this process must 20 minutes, that is again occur that web break will restart combustion furnace (RTO), must wait for 20 minutes, this has had a strong impact on the operational efficiency of whole coating system.
Summary of the invention
For solving above technical deficiency, the utility model provides the high heat accumulation type off-gas incinerator of a kind of operational efficiency.
The utility model is realized by following measures:
A kind of heat accumulation type off-gas incinerator of the present utility model, comprises combustion furnace, baking oven and heat exchanger,
Combustion furnace is connected with heat exchanger by warm-air pipe, described heat exchanger is connected with baking oven by warm-air pipe, combustion furnace is connected with natural gas line, described natural gas line is provided with automatic valve III, also comprise return fan and new blower fan, between the air inlet of described return fan and baking oven, be connected with return air duct I, between the air outlet of return fan and combustion furnace, be connected with return air duct II, the air outlet of return fan is also connected with exhaust duct, described exhaust duct is provided with automatic valve I; Described return air duct II is provided with automatic valve II, and the air outlet of described new blower fan is connected with new wind inlet pipe, and described new wind inlet pipe is connected on the return air duct II between automatic valve II and combustion furnace, and new wind inlet pipe is provided with automatic valve IV.
Above-mentioned heat exchanger is connected with circulating fan and tail gas comb.
The beneficial effects of the utility model are: after web break, and combustion furnace can start rapidly, thus adds effective production time, enhances productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 combustion furnace, 2 heat exchangers, 3 baking ovens, 4 warm-air pipes, 5 return fans, 6 new blower fans, 7 return air duct I, 8 automatic valve I, 9 exhaust ducts, 10 automatic valve II, 11 return air ducts II, 12 automatic valve IV, 13 natural gas lines, 14 automatic valve III, 15 circulating fans, 16 tail gas combs.
Detailed description of the invention
Below in conjunction with accompanying drawing, further detailed description is done to the utility model:
