Technical field
The present invention relates to ink printing baking oven emission treatment field, and in particular to a kind of water-based ink prints the ethanol of baking oven
Retracting device.
Background technology
For ink printing baking oven discharge, existing solvent recovering system is directed to benzene class or esters solvent, uses elder generation
Compression, then rectifying, the method such as extraction, energy consumption is big, and effect is also poor.Existing combustion method (RTO) handles VOCs methods also not
It is adapted to water-based ink, because the concentration of alcohol of ink printing discharge is low, it is difficult to burn, and if in 3.3%-19% scope wine
Insufficient meeting of being burnt if smart concentration can even set off an explosion.
Stage now, water-based ink will replace traditional solvent-based ink (mixed solvent based on esters), be applied to
Plastic printing, still acquires a certain degree of difficulty.Because the rate of drying of water is very slow, being using the water-based ink of 100% water can not
Meet the condition of ink setting in high speed printing.So aqueous ink manufacturer can add a 20%-40% left sides in ink formulations
Right ethanol, is also the mixed liquor of water and ethanol moreover, needing the diluent of addition in printing process.So, ethanol plus
Enter exactly to adjust rate of drying of the water-based ink in printing process with this.It is a kind of indispensable adding ingredient.Ethanol

Gas-liquid mixed cavity 6 is connected by discharge duct 2 with outside or aftertreatment device;Set on the gas-liquid mixture mixing chamber 6
There are water inlet 3 and alcohol-water mixture outlet 5.
Further, it is arranged in parallel using two closed containers, two closed containers have common admission line 8 and row
Feed channel 2, is recycled using two closed containers of Valve controlling alternately ethanol.
Further, a closed container is at least arranged in series after closed container again, for further lifting discharge
The clearance of Ethanol in Gas.
Further, at least it is being arranged in series an ethanol absorption tower water circulation spray after the closed container of end
Tower, the clearance for further lifting ethanol in discharge gas.
Further, ethanol content on-line detector 4, the ethanol are additionally provided with the gas-liquid mixture mixing chamber 6
Content on-line detector 4 is connected with control system signal, the control system and the valve of each gas-liquid channel on closed container
Signal is connected.
Further, at least it is being arranged in series an ethanol absorption tower water circulation spray after the closed container of end
Tower, the clearance for further lifting ethanol in discharge gas.The ethanol absorption tower water circulation spray equipment includes first
To N grades of ethanol absorption towers, ethanol absorption towers at different levels are equipped with independent circulation water sprinkler system;N-1 grades of ethanol absorption towers
Top and the gas passage being communicated with the middle part of N grades of ethanol absorption towers;The bottom on N level ethanol absorption tower and N-1 grades of ethanol
The top on absorption tower have together with fluid passage, the fluid passage is provided with backflow water pump and control valve;Ethanol at different levels
Ethanol content on-line computing model 4 is provided with absorption tower.
The beneficial effects of the present invention are:
1) using water and the good compatibility of ethanol, by gas-liquid mixed, the purpose for reclaiming ethanol in baking oven exhaust is reached,
Use two closed containers in parallel, alternation, the continuity that system can be kept to work.
2) using the closed container that two or more are connected, the ratio that ethanol is reclaimed, reduction VOC rows are further ensured that
Put.
3) it is follow-up to continue to carry out circulated sprinkling using ethanol recovery tower, the purity that ethanol is reclaimed is improved, while improving VOCs
The effect of removal.
4) using the on-line checking of alcoholic strength measuring instrument, using gate-controlled switch, the ethanol water mixed liquid of prescribed concentration is obtained.
5) clean air can be discharged directly, also the recoverable formation circulatory system.
6) ethanol recovery scheme of the present invention, economic, energy-conservation, has operability.
