Description

Machine room bioanalysis VOCs gas purge system
Technical field
The utility model relates to removing and the cleaning system of VOC (VOCs) gas, especially a kind of bioanalysis VOCs gas purge system being suitable for packages printing workshop.
Background technology
The tail gas of plant emissions or the interior space often work the mischief to environment and human body containing VOC (volatile organic compounds), therefore must implement to process to reduce its content accordingly.Along with the sustainable and stable development of the fast development of the upstream ink industry of national economy and press-packaging industry, print reproduction industry developed rapidly in recent years, had become the pillar having become cultural industry.The pollutant of printing industry primary discharge is the organic exhaust gas containing VOCs, the VOCs volatilization that miscellaneous ink that VOCs wherein mainly uses from packages printing, organic solvent and adhesive and explained hereafter cause is one of important VOCs industrial source.
Scrubbing tower is common VOCs treating apparatus, and it VOCs is dissolved in liquid phase and removes from gas phase, the cleaning solution used normally water, but VOCs in waste water still can natural loss and produce stench.
Also utilize bioanalysis to be processed, namely utilize the digestion of microorganism to decompose VOCs, bioanalysis takes up an area comparatively large, and microorganism cultivates the needs more time, and therefore setup time is longer.In order to make microorganism can decompose VOCs efficiently, also must control the epidemic disaster of its growing environment, it is higher that it maintains difficulty.In addition, due to the longer processing time need be spent with Biochemical method VOCs, allow microorganism have time enough digest VOCs. therefore bioanalysis be not generally suitable for a large amount of exhaust-gas treatments.
Also someone utilizes concentration runner process VOCs, but adopts the way process VOCs of concentrated after-combustion due to concentration runner, and it is higher that it builds cost.
The bioanalysis VOCs gas clean-up device the most close with the application is applied to waste gas deodorization the earliest.Biofiltration process is that attached growth of microorganisms is on solid dielectric (filler), waste gas is adsorbed by the fixed bed (packing layer) be made up of medium, is absorbed, finally be degraded by microorganisms, more typically have biofilter and bio-trickling filter two kinds.Existing biological reaction apparatus has the following disadvantages, one is that floor space is larger, in the reaction time that biological deodorizing reaction needed is longer, waste gas needs in bioreactor, have the stop of long period just can reach good removal effect, the inevitable like this floor space wanting augmenting response device.Two is that existing product is bad to complicated component waste gas pollution control and treatment effect, harmful components relative complex in waste gas, some is that organically some is inorganic, organic principle has again a variety of, and the harmful components removed in waste gas must be cultivated and played the microorganism of better removing to harmful components and provide a good growing environment to it.Existing product can not meet the good growth of Different growing environment microorganism, bad to difficult waste gas effect, some waste gas product after microorganism preliminary exposition still has certain peculiar smell and harmfulness, also needs to absorb further through another kind of microorganism and process again could become completely without basement composition.So also have not enough for difficult waste gas existing product.
The utility model patent of notification number CN203853018U discloses the biological method purification device of a kind of industrial volatile organic waste gas and foul gas, this patent is by upper, the lower stacked reactor cell body that is composed in series of two-layer biological reaction pool, one deck liquid storage district is set gradually from bottom to top in one deck reaction tank of bottom, one deck gas distribution dividing plate and supporting, one deck carrier supporting layer, one deck bio-carrier, one deck shower humidification system, two layers of reaction tank above cover plate supporting are set above one deck reaction tank, be communicated with two layers of reaction tank of top with gas passage, two floor liquid storage districts are set gradually from bottom to top in two floor reaction tank, two layers of gas distribution dividing plate and supporting, two layers of carrier supporting layer, two layers of bio-carrier and two layers of shower humidification system, exhaust outlet is provided with at reactor cell body napex.Although this patent has wide adaptability, floor space is little, structure is simple, simple to operate advantage, still there is the defect that treatment effeciency is inadequate, clean-up effect is not enough in the process for the VOCs gas of high concentration, large-area machine room.The requirement of packages printing industry VOCs gas purification can not be adapted to.And this device can only click operation, the VOCs gas for process large area machine room is substantially unable to do what one wishes, is difficult to reply.
