Technical field
The present invention relates to post health and field of Environment Protection, more particularly, it relates to on-line regeneration can be adsorbed by the on-the-spot harmful smoke cleaning system of resin sand casting expected.
Background technology
Along with the development of casting technique, China's casting widely used self-hardening furan resin already, phenolic resin sand molding, this not only shortens the production cycle, improves production efficiency, and also improves the visual quality of casting. But resin bonded sand mould is when cast and cooling, dense flue gas can be given out, because of the baking by high temperature aluminum water, molten iron and molten steel, smoke components does not only have flue dust and CO, also can produce the organic substance that decomposes out and the bigger resin oiliness volatile matter of viscosity, these resin oiliness volatile matters mix with flue dust can produce the viscosity greasy thing of very strong and inflammable black, it is easy on the filter bag of tube wall and the sack cleaner being bonded at dust removal by ventilation pipeline, time one length can make resistance of the filter bag be increased up blocking, thus causing that filtering function lost efficacy. Therefore, the foundry industry of current China is on phenolic sand molding production line, and the flue gas generally individually employing blower fan of all cast sections and cooling vestibule is in line, it is not provided with cleaner unit, which results in pollution transportation, though cleaning of indoor environment, but pollute air, discharge not up to standard. These are mixed in air and form organic exhaust gas, not only cause environmental pollution, and injured the healthy of people, and the Organic Waste Gas Pollution in Foundry Production has become one of focal issue of industry concern. Take economy, effective method to solve the Organic Waste Gas Pollution problem in Foundry Production, the Ecological Civilization Construction of casting industry sustainable development and China is had important practical significance.
The governing problem containing other composition organic exhaust gas (can effectively filter exhaust gas dust and can effectively process again harmful gas) at present foundry produced, yet there are no relevant report, and foundry's Organic Waste Gas Pollution control is just at the early-stage.
But, in industries such as oil, chemical industry, printings, to VOCs treatment existing diversified economy, effective processing method. But, owing to casting industry organic exhaust gas organic concentration is low, the features such as gas production is few, it is difficult to directly the organic waste gas treatment method of above-mentioned every profession and trade directly be indiscriminately imitated use.
