Miscellaneous effect.Containing alcohol formaldehyde enters formaldehyde knockout tower through entrance, carries out the material after formaldehyde gas purified treatment in formaldehyde knockout tower
From essence aldehyde outlet output.
Further, the both sides of described purifying column are relatively set with agitator arm, and described agitator arm passes with stirring motor
Dynamic connected, by the agitation of agitator arm, make the removal of methanol in containing alcohol formaldehyde more thorough, improve separation efficiency.
Further, the top of described purifying column is provided with fluid infusion mouth, and bottom is pyramidal structure and is provided with leakage fluid dram, fluid infusion mouth
It is equipped with valve with leakage fluid dram, improves the replacing efficiency of formaldehyde gas purified solution, make formaldehyde gas clean-up effect more preferable.
Further, the lower end connection of described airway has aeration head, described aeration head is the annular with some solarization air caps
Tubular structure, described solarization air cap outwards dissipates and is distributed in annular, increase the contact area of gas and reaction solution, increases and inhale
Producing effects rate, that can be removed by the methanol in containing alcohol formaldehyde is more thorough.The outer layer of described aeration head is gas-phase silicon rubber layer, elastic
Height, when without aeration pressure, solarization air cap can close voluntarily, thus prevents blocking and the pollution of solarization air cap.
Further, described essence aldehyde outlet purifies reboiler also by formaldehyde gas decontamination cycle feed back bifurcations with formaldehyde gas
Being connected, described formaldehyde gas purifies reboiler and is connected with the arrival end of described aerator, divides through formaldehyde gas decontamination cycle feed back
Prop up mouth and enter the purification reboiler heating of formaldehyde gas, then return to formaldehyde knockout tower through formaldehyde gas decontamination cycle feedback outlet, improve
Separating effect.
The utility model has the advantage of: the dispersion effect of gas is poor, improves clean-up effect, reduces and produces into
This, improve economic benefit.
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
