Its operation principle is：Main component is carbon dioxide, chlorine in the waste gas produced from benzyl chloride hydrolysis, waste gas
Change the gases such as benzyl, phenmethylol, benzaldehyde.Waste gas is pooled in off-gas buffer tank 1 first, then from the bottom of normal temperature spray absorber 2
Portion's air inlet enters in tower, and normal temperature spray absorber 2 uses normal temperature soft water, and normal temperature soft water is continuously transported to tower by pump
The mixture of triethanolamine and quaternary ammonium base is added in top, normal temperature shower water and the waste gas counter current contact of ejection, normal temperature shower water, is mixed
The mass ratio that compound accounts for normal temperature shower water is 0.001-0.002, and the absorption spray phase can absorb most organic in waste gas
Gas.Meanwhile, continuously moisturizing and water outlet are carried out to following absorption water tank, it is ensured that the continuity of absorption spraying effect,
The waste water that delivery port comes out enters wastewater collection tank.
By normal temperature spray column 2 absorb after waste gas again from freezing spray column 3 bottom inlet enter tower in, by spray inhale
The waste gas of receipts enters back into freezing spray process, and normal temperature soft water is continuously transported to the freezing tower top of spray column 3 by pump, in tower
Interior and waste gas counter current contact.Unlike, soft water can be down to 0-3 DEG C after refrigerator exchanges heat, and chilled water has added mass ratio
0.001-0.002 black tropine, there is more preferable assimilation effect to organic gas, and the stage can be 90% remaining in basic absorption waste gas
Organic gas, meanwhile, continuously moisturizing and water outlet are carried out to following brine tank, it is ensured that absorption spraying effect it is continuous
Property, the waste water that delivery port comes out enters wastewater collection tank.
The waste gas come out from freezing spray column 3 enters the bottom of charcoal trap 6 by pipeline fan again, from lower
In upper absorption process, it can not will be adsorbed using activated carbon physical adsorption process in waste gas by the organic gas of spray-absorption, it is living
The a diameter of 2.0-2.8mm of property carbon particle.Regenerating active carbon process uses high-temperature steam, and the condensed waste water of steam participates in benzyl chloride
Hydrolysis.
By the absorption of charcoal trap 6, the organic gas in waste gas is adsorbed completely, and charcoal trap 6 is suction
The pattern that attached-parsing is used alternatingly, when a tower absorption, another tower is parsed with high-temperature steam, the height parsed
Warm waste gas enters wastewater collection tank after being condensed by condenser 61.
The waste gas adsorbed from charcoal trap 6 is entered in absorbing by liquid caustic soda tower 7 by its top gas outlet, volumetric concentration
Be 48% sodium hydroxide liquid by being pumped at the top of spray column, carry out counter current contact with waste gas, the process will be remaining in waste gas
Carbon dioxide all sponge.The soda ash solution that liquid caustic soda is produced with carbon dioxide reaction, waste water tank is entered by delivery port,
When the PH of liquid caustic soda water tank is less than setting value, liquid caustic soda is added by mending alkali mouthful.Waste water in wastewater collection tank is adsorbed into waste water
