The waste discharge not only causes great energy waste but also causes air pollution due to the discharged gas.
When the waste gas generated in the printing industry is purified, the waste gas components generated by different printing processes and different coatings used for printing are different. Therefore, when the organic waste gas treatment method is selected, the method should be selected according to the waste gas components, concentration and the like. Generally, the organic waste gas treatment method is selected according to the following factors in general: the type of organic pollutants, the concentration level of organic pollutants, the exhaust temperature of organic waste gas, the discharge flow of organic waste gas, the level of particulate emission, and the level of pollutant control to be achieved.
The end treatment technologies for VOCs currently on the market can be divided into two main categories: recovery techniques and destruction techniques. Wherein the recovery technology is a method for enriching and separating organic pollutants by changing temperature and pressure or adopting methods such as selective adsorbents and selective permeable membranes through a physical method, and mainly comprises an adsorption technology, an absorption technology, a condensation technology, a membrane separation technology and the like; the destruction technique is to convert organic compounds into CO by chemical or biochemical reaction with heat, light, catalyst or microorganism2And H2The methods of O and the like mainly comprise high-temperature incineration, catalytic combustion, biological oxidation, low-temperature plasma destruction, heterogeneous (photo) catalytic oxidation technology and the like.
In gravure printing, the raw and auxiliary materials mainly containing VOCs are solvent-based ink and water-based ink, the discharge characteristic of VOCs is that VOCs are discharged in the printing and drying processes, the solvent-based ink is used, and the discharge concentration of VOCs is higher; with aqueous inks, the concentration of VOCs emitted is low. VOCs characteristic contaminants are ketones, alcohols, ethers, esters and aromatic hydrocarbons.

Since the induced separation column 22 is continuously rotated and the separation cylinder 24 has a tapered structure, a vortex wind is formed inside the tapered cavity 241 and the induced separation column 22. Because the side wall of the induced separation column 22 comprises at least two mesh plates 222 and the adsorbing material 223 clamped between the two mesh plates 222, and the adsorbing material 223 has a strong adsorption function on water vapor and organic gas, after the waste gas with organic gas and a small amount of water vapor passes through the flame retardant chamber 1 and enters the separation purification chamber 2, the waste gas can enter the upper part of the separation purification chamber 2 along the gas channel 21 and enters the conical cavity 241 of the separation cylinder 24 from the communication hole 25, and under the action of vortex wind, the concentration of organic matters in the gas close to the induced separation column 22 in the conical cavity 241 is high, and the gas collides ceaselesslyAdsorbed on the lateral wall of induced separation post 22, after organic gas adsorbs the saturation, waste gas enters into and holds chamber 26, when the organic gas concentration sensor who holds in the chamber 26 detects organic gas's concentration and exceeds standard, organic gas concentration sensor can signal for induced separation post 22's circular telegram otter board 222 forms the short circuit and emits high-tension electricity, the organic gas of absorption splits under powerful electric current effect on the lateral wall of induced separation post 22, partial organic gas decomposes and generates CO2And H2O, part of the gas is split into carbon and hydrogen and a small amount of oxygen, so that organic waste gas is removed, excessive water vapor and CO produced2And the air, together with the relatively non-contaminated gas away from the induced separation column 22, is discharged through the bottom of the induced separation column 22 to the accommodating chamber 26, and further into the flame-retardant drying chamber 3.
The particle material with the functions of flame retardance and drying in the rolling flame-retardant drying chamber 3 further acts on redundant steam and generated CO2And the fire extinguishing and fine filtering are carried out with the air in a precautionary manner, so that the flame retardance and the drying of the gas are realized, and the waste gas can be recycled.
When the particle materials in the flame-retardant drying chamber 3 are adsorbed and saturated, the particle materials can be degassed and dedusted through high-frequency oscillation for recycling.
