Introduction to the industry
The automotive industry is a fast-growing industry with many car brands competing in a market that is often difficult to meet. The automotive industry is a comprehensive enterprise developed on the basis of many related industries and related technologies. Products from many sectors are used in automobiles, and various types of processing technologies are required from rough machining to complete vehicle assembly. Automotive parts include thousands of different components ranging from floorboards to screws. The actual automotive production process is done in co-operation with a number of different specialised production plants (workshops)
Pollution Hazards
Automobile shell in the manufacturing production process will exist cutting, welding, welding and other operations are indispensable important process in the process of operation, will produce a large number of welding fume, workers long-term inhalation of welding fume, will cause dizziness, headache, coughing, chest tightness shortness of breath and other symptoms, resulting in fibrous lesions of the lung tissue, i.e., the welder's pneumoconiosis, and accompanied by complications such as manganese poisoning, fluorine poisoning and metal fume fever.
Overview of the treatment programme
For automotive welding exhaust VOCs treatment technology, nowadays, in line with the environmental emission requirements, and play a role in reducing the cost and efficiency of the treatment technology, is to use the combustion method of treatment technology is more economical and energy-saving and effective. The use of dry filters + reduced wind concentration + catalytic combustion combination of governance, governance can meet the emission requirements after the standard!
Process flow
Automobile welding exhaust gas treatment first through the three-stage dry filter, removing 99% of the particles in the dusty gas, so that the organic matter is completely clean, but also to increase the operating efficiency and service life of the equipment in the later stage. Separation of organic gases into the zeolite turn concentration or molecular sieve adsorption concentration of organic waste gas low concentration into high concentration, large air volume conversion of small air volume to reduce the wind to increase the principle of concentration.
When the adsorption concentration reaches the required self-combustion requirements, and finally through electric heating to warm up the high temperature gas of 80-100 degrees for desorption and regeneration, desorption down to the high concentration of the use of CO catalytic furnace, with the help of catalysts to make the organic waste gas in the lower temperature of ignition under the flameless combustion, so that the organic exhaust decomposition of carbon dioxide and water vapour into non-toxic.
Other treatment technology programmes
Low concentration and small air volume of automobile welding 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 of automobile welding 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 of automobile welding exhaust gas can be used: pretreatment + zeolite rotor concentration + catalytic combustion or pretreatment + zeolite rotor concentration + RTO thermal storage incinerator and so on.
