Description
Technical field
The present invention relates to VOCs treatment field, particularly relate to a kind of organic exhaust gas adsorption scavenging agent and its preparation method.
Background technology
The gaseous pollutant of industrial discharge is one of important source of topsoil, wherein organic exhaust gas is that a kind of quantity discharged is big, pollution face is wide and human body and environment all has the gaseous pollutant of serious harm effect, it extensively derives from the coating operation of the chemical preparationss such as paint, coating, lubricating oil, and its main component is volatile organic compounds (VOCs). Owing to it is to the considerable damage effect of human body and physical environment, obtain the concern of government, enterprise and the common people gradually.
The treatment process that organic waste-gas purification technology is commonly used at present has burning method, chemical oxidization method, chemical absorption method, absorption method, biological process etc. Wherein absorption method is a kind of conventional organic waste-gas purification effective ways, is the method utilizing various solid adsorbent (such as gac, activated carbon fiber, molecular sieve etc.) that the pollutent in discharging waste gas carries out adsorption cleaning. Absorption method equipment is simple, applied widely, purification efficiency height, is a kind of traditional waste gas pollution control and treatment technology, is also Treatment process most widely used at present. The quality of adsorption cleaning performance depends mainly on the performance of sorbent material, and domestic current sorbent material is generally granulated active carbon and activated carbon fiber.
Absorption method research finds, the oxygenizement of sorbent material in adsorption process, sorbent material can be caused to heat up because of heat release so that take activated carbon as the danger that the sorbent material of carrier at high temperature has spontaneous combustion. Zeolite is a kind of silicoaluminate with high-specific surface area, high porosity, and its thermostability is higher, and being in recent years used in the removal of volatile organic matter has the trend replacing activated carbon gradually.
