Industry introduction
Electronic factory welding is for electronic products such as: circuit boards, electronic components, circuit boards, PCB boards and other products, electronic components are entering a new generation of new electronic components as the main components of the era, which will basically replace the traditional components, electronic components from the original only to adapt to the miniaturisation of the machine and its new process requirements based on the improvement to meet the digital technology, microelectronics technology development put forward by the Characteristics of the requirements of the main, and is a complete set to meet the stage of industrial development.
Pollution hazards
Electronic factories in the processing and production process used in the reflow soldering and wave soldering process will produce organic matter non-methane hydrocarbons. The exhaust welding process, due to high temperature so that the metal, welding rod flux skin, dirt, paint and other substances, evaporation or combustion, the formation of vapour, dust, can cause poisoning. The fumes of non-ferrous metals are, in general, toxic, and one type of poisoning is manganese poisoning. Therefore, it needs to be purified after being collected and collected by a mobile gas collector in the workplace.
Overview of the treatment programme
For the welding industry in the electronics factory VOCs treatment technology, now in line with environmental emission requirements, and play a role in reducing the cost and efficiency of the treatment technology, is the use of combustion method of treatment technology is more economical and energy-saving 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
Electronic factory 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 later equipment operating efficiency and service life. 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 programme
Low concentration and small air volume of electronic factory 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 electronic factory welding 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 electronic factory welding exhaust gas can be used: pretreatment + zeolite rotor concentration + catalytic combustion or pretreatment + zeolite rotor concentration + RTO thermal storage incinerator and so on.
