Introduction to the Sheet Metal Works Industry
Sheet metal products are a comprehensive cold working process for thin metal sheets (usually under 6mm), including shearing, punching/cutting/compounding, folding, welding, riveting, splicing, forming (e.g. car body), etc. Its distinguishing feature is the consistent thickness of the same part. The products processed through the sheet metal process are called sheet metal parts. Sheet metal parts referred to by different industries are generally different, and are mostly used in grouping when called.
Pollution Hazards in Sheet Metal Plants
Pollution hazards in sheet metal factories are mainly the generation of volatile organic emissions from welding, laser, and paint spraying processes. This type of exhaust gas usually belongs to the general term of non-methane hydrocarbons, spray painting is the use of paint and solvent mixing and blending operations produce paint mist, the main components are benzene, toluene, xylene, formaldehyde, phenol and other volatile organic compounds, these components have a strong irritating odour of the gas with a volatile, high toxicity characteristics.
Overview of paint spraying treatment programme for sheet metal factory
For the sheet metal factory paint exhaust VOCs treatment technology, now in line with environmental emission requirements, and play a cost-effective treatment technology, is to use combustion method of treatment technology is more economical and energy-saving. It is recommended to use: wet jet washing (multi-pipe) + dry filter + wind reduction and thickening + catalytic combustion combination of governance, governance can meet the emission requirements of standards!

Sheet metal factory paint exhaust treatment 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 is saturated by electric heating at high temperature (100-180 ℃ C) desorption of VOCs substances, desorption of high concentrations of organic waste gas directly into the catalytic combustion co, through the accelerated oxidation of high concentrations of waste gas by precious metals, in ( 250-380 ℃) high temperature purification and oxidation of harmless carbon dioxide (CO2) and water vapour (H20) and discharge to the atmosphere to meet the standards.
Other treatment process technology
High concentration of small air volume hardware factory paint exhaust 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 hardware factory paint waste gas can be used: pretreatment + zeolite rotor concentration + catalytic combustion or pretreatment + zeolite rotor concentration + RTO thermal storage incinerator and so on.
