Description
Technical field
Chemical industry of the present invention relates to a kind of gas recycling device.
Background technology
If the synthetic venting of speeding, Gas-making Furnace blowing-out gas and the air blast that produce in Chemical Manufacture are directly discharged in air both contaminated environment, waste energy again, because contain CO, N2, H2, NH4, CH4 in this three gas, the recycling of therefore carrying out three gas is most important.Existing three gas recovering devices are burnt and are obtained high-temperature gas by three gas in combustion furnace, then high-temperature gas is incorporated into heat exchange in boiler and produces steam, the steam producing can apply in other operations, and the flue gas after heat exchange is discharged in air after by dedusting.There is following defect in this three gas recycle devices, part fuel gas is fully burning not, and the high-temperature gas after burning is directly discharge after boiler heat exchange, and heat exchange is not thorough, and thermal loss is large, and exhaust emissions temperature is high.
Summary of the invention
The object of this invention is to provide a kind of novel three gas recovering devices, can fully burn and heat exchange more thorough, can effectively improve heat recovery efficiency and steam production, reduce the content of fuel gas in the temperature of last emission gases and emission gases.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of novel three gas recovering devices, the discharge duct of the venting buffering of speeding stove and cyclone dust removal stove is communicated with the air inlet of combustion furnace respectively, the exhaust outlet of combustion furnace is connected to heat-exchanger rig, heat-exchanger rig is connected with exhaust apparatus, it is characterized in that: described combustion furnace inwall is provided with polylith deflection plate the interlaced longitudinal arrangement of deflection plate.
?described heat-exchanger rig comprises high pressure waste heat boiler, low pressure waste heat boiler and the air preheater connecting successively, the discharge duct of low pressure waste heat boiler is connected to the horizontal air inlet of air preheater, laterally between air inlet and horizontal gas outlet, be provided with many heat exchanging pipes, air preheater is longitudinally provided with longitudinal air inlet and longitudinal gas outlet, described longitudinal gas outlet is connected to the discharge duct of cyclone dust removal stove, and laterally gas outlet is connected with exhaust apparatus.
?described exhaust apparatus comprises granite duster and the chimney being communicated with granite duster exhaust outlet.
Novel three gas recovering devices provided by the invention, change existing straight barrel type combustion furnace into combustion furnace that inwall is provided with polylith deflection plate, thereby extend fuel gas in the burning time of combustion furnace, and combustible gas physical efficiency is fully burnt, and increase quantity of heat production; Existing heat-exchanger rig is only provided with heat exchange boiler, in the present invention, after high pressure waste heat boiler and low pressure waste heat boiler, added air preheater, gas after boiler heat exchange is passed in air preheater, by air blast be blown into cold air again with heat exchange after gas carry out heat exchange, can further reduce the temperature of emission gases, in addition, using the cold air after heat exchange as air blast, pass into combustion furnace and promote burning, can reduce thermal loss, improve heat utilization efficiency.
