Industry Introduction
The food and beverage industry facilitates the preservation and storage of food products, thus giving rise to product packaging bags. Food packaging bags are film containers that are in direct contact with food and are used to hold and protect food. Food-grade plastic film should be used for production, generally more than two layers of composite packaging bags. Can be divided into: ordinary food bags, vacuum food bags, inflatable food bags, boiled food bags, steamed food bags and functional food bags and so on.
Pollution hazards
Food and beverage packaging bags coating and printing process will produce a large number of vocs waste gas, the use of coating machine process, the waste gas is mainly coated and its subsequent drying process produces a high concentration, high temperature, high heat recovery value of the vocs waste gas, the main components are benzene, ethyl acetate and a variety of esters and so on.
Overview of the treatment programme
For the food and beverage packaging industry coating machine VOCs exhaust gas treatment technology, now in line with the environmental emission requirements and heat saving treatment technology, the use of regenerative combustion method of treatment technology is more economical and energy-saving effective. Wet jet washing (multi-pipe) + dry filter + wind reduction and thickening + regenerative incinerator RTO combination of governance, governance can meet the emission requirements of the standard!
Process flow
Wet jet washing (multi-tube) + dry filtration + zeolite rotor adsorption concentration + catalytic combustion process (integrated system) process treatment. Organic waste gas is collected through the pipeline, and enters the pretreatment wet jet tower to remove paint dew, acidity and particles of purification. After purification, the gas is introduced into the dry filter to remove particles and zeolite adsorption of hazardous substances, and the organic waste gas is then sent to the zeolite adsorption bed device, and the VOCs in the waste gas is absorbed by the zeolite and then discharged to the atmosphere in compliance with the standards. When the zeolite adsorption bed saturated by electric heating high temperature (100-280 ℃ C) desorption of VOCs substances, desorption of high concentrations of organic waste gas directly into the heat storage ceramic body, through the heat storage ceramic body of the organic waste gas temperature to 760 degrees, so that the organic waste gas in the 760-860 degrees between the combustion of high temperature purification and oxidation of harmless carbon dioxide (CO2) and water vapour (H20) and Discharged into the atmosphere according to the standard.
Other treatment technology solutions
Low concentration and small air volume pressure vessel exhaust gas can be used: spray tower, uv photolysis purifier, activated carbon adsorption and other single or multiple combinations of processes for treatment;
High concentration of small air volume pressure vessel exhaust gas can be used: pretreatment + zeolite molecular sieve + catalytic combustion, pretreatment + zeolite molecular sieve + RTO thermal storage incinerator, a single catalytic combustion device or a single RTO thermal storage incinerator and so on;
High concentration and large air volume pressure vessel exhaust gas can be used: pretreatment + zeolite rotor concentration + catalytic combustion or pretreatment + zeolite rotor concentration + RTO thermal storage incinerator and so on.
