The heat exchanger provided by the invention has the advantages of sufficient heat exchange and high heat utilization rate.
Description
Technical field
The present invention relates to a kind of heat exchanger, exactly is a kind of organic waste gas catalytic combustion heat exchanger.
Background technology
When the high levels of organic solvents in the activated carbon adsorption bed is carried out desorption, need clean air, and make it to reach the boiling point of solvent, thus organic solvent desorption from active carbon is come out, the high levels of organic solvents that desorption is come out is introduced catalytic combustor and is carried out catalytic combustion then.Can produce a large amount of heats in the catalyticing combustion process of organic solvent, for making full use of this part heat energy, the designer is provided with heat exchanger in catalytic combustion equipment, gives the activated carbon desorption air that needs intensification with the exchange heat that produces in the catalyticing combustion process.Present stage, heat exchanger commonly used was the box passage that a uncovered does not have the end, was provided with some circulation of air pipes perpendicular to channel direction in the box passage.Box passage is an activated carbon desorption air duct, and the circulation of air pipe is the exhaust steam passage that catalytic combustion produces.When the waste gas percolation of catalytic combustion generation is crossed the circulation of air pipe, heat transferred circulation of air pipe; When activated carbon desorption passage of air is crossed this box passage, contact with the circulation of air pipe, according to heat-conduction principle as can be known, cold activated carbon desorption air at this moment can be subjected to the conduction of thermal air current siphunculus, produces a temperature-rise period.But this heat exchanger exist exchange heat not exclusively, heat energy utilization rate variance, energy consumption height, equipment handover charge be with high defective.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, the catalytic combustion heat exchanger that a kind of exchange heat is abundant, the heat energy utilization rate is high is provided.
Technical solution of the present invention is: a kind of catalytic combustion heat exchanger, it comprises orthogonal burnt gas passage of airflow direction and desorption air duct, it is characterized in that: burnt gas passage and desorption air duct are flat and thin sheet pipeline, and alternately stack is provided with, and burnt gas passage and desorption air duct are respectively two to 30 layers.
Furtherly, burnt gas passage and desorption air duct inner chamber height are the 30-50 millimeter.
Furtherly, because burnt gas passage and desorption air duct tube wall are very thin, for preventing the tube wall thermal deformation, support tube wall, slow down the flow through speed of passage of gas simultaneously, improve rate of heat exchange, in burnt gas passage and desorption air duct, corrugated plating is set respectively.Described corrugated plating can be shapes such as triangle ripple flap, circular arc corrugated plating, square corrugated flap, trapezoidal ripple flap.
Furtherly, in order to reduce the consumption of heat, pipe thickness, block board thickness between burnt gas passage and desorption air duct are respectively the 1-3 millimeter.
Advantage of the present invention is: 1, because burnt gas passage and desorption air duct are flat and thin sheet pipeline, and alternately stack setting of multilayer, therefore, the burnt gas of cold desorption air and heat carries out heat exchange in the form of sheets, the area of heat exchange is big, and heat exchange is abundant; 2, owing in burnt gas passage and desorption air duct corrugated plating is set respectively, therefore, gas flow rates is slower in the process of heat exchange, and heat exchange is abundant; 3, because the tube wall of burnt gas passage and desorption air duct is very thin, so thermal losses is little.
