Description
Technical field
The present invention relates to post health and field of Environment Protection, more particularly, it relates to the thermoplastic resin sand coremaking waste gas cleaning system expected can be adsorbed on-line regeneration.
Background technology
Development along with foundry engieering, organic binder bond moulding, the core-making techniques such as hot box, cold-box, shell core and resin self-setting sand technique are widely used, by organic substances such as free generation or the aldehydes of decomposition generation, phenols, amines in organic binder bond application process, it is mixed in air and forms organic exhaust gas, not only cause environmental pollution, and injure the healthy of people. Therefore, 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 organic substance that in Foundry Production, organic exhaust gas is mainly derived from the organic substances such as the aldehyde, the phenol that separate out from organic binder bond middle reaches and organic adhesive dosage form (core) sand decomposes out casting process. During as adopted shell core technique, shell processed and casting process can produce the gas such as phenol, formaldehyde; When adopting triethylamine cold core box core process, coremaking and phenol, formaldehyde and Triethylamine gas can be produced in casting process; When adopting hot-box core making process, coremaking and the gases such as urea aldehyde, formaldehyde, Blausure (German) can be produced in casting process. These organic gas and air have been mixed to form the organic exhaust gas of foundry. Respiratory mucosa is had stimulation by formaldehyde, and long-term chronic stimulates can cause mucosa hyperemia, brings out respiratory inflammation. Skin, mucosa are had strong corrosiveness by phenol, can suppress the nervus centralis of people, the Liver and kidney function of infringement people. The respiratory tract of people is had strong impulse by triethylamine, corrodes oral cavity, esophagus, even causes pulmonary edema to cause death, can cause chemical burn with contact skin. As can be seen here, the organic exhaust gas produced in Foundry Production not only pollutes environment, and seriously damages the healthy of people.
In the organic exhaust gas that foundry produces, organic concentration is low, and its environment caused and personal injury are recognized deficiency by foundry enterprise. At present, the improvement containing triethylamine organic exhaust gas that foundry produces for cold core coremaking has been reported, one is processed containing triethylamine waste gas by phosphoric acid spray-absorption method, reach discharge standard, but create the waste water containing amine salt in the process, as environment is caused secondary pollution by untreated meeting. Two is utilize impulse electric corona method to process containing triethylamine waste gas, it is currently under the laboratory research stage, and to the governing problem containing other composition organic exhaust gas that foundry produces, yet there are no relevant report, 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, efficient system. 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 exhaust gas system of above-mentioned every profession and trade directly be indiscriminately imitated use.
