Description
Technical field
The present invention relates to industrial waste gas purifying field, particularly relate to a kind of low concentration, Wind Volume, high abnormal flavour waste gas concentration energy equipment and technique thereof.
Background technology
" concentration is low, large-minded, component is many, abnormal flavour dense " is the product dirt feature of common industrial organic exhaust gas.Along with the continuous of ambient atmosphere prescription is promoted by resident, increasing blowdown enterprise is faced with " abnormal flavour complaint " puzzlement, and meanwhile, the enforcement of pollution discharge levy system has beaten alarm bell also to blowdown enterprise, enterprise wants the development of long-term stability, it is necessary to solve waste gas Peculiar Smell.And some common at present VOCs treatment technology, such as high temperature incineration method, absorption process, plasma method, photocatalytic oxidation etc., due to many-sided reasons such as economy, technology and management, it is difficult to meet environmental requirement now and from now on.
Traditional absorption-catalytic decomposition process is due to competitive Adsorption, the purification efficiency causing multicomponent pollutant is restricted, if the absorption band of adsorbent is long easily occurs that in desorption process peak value causes safety problem, totally do not cause easily caused by desorption that next round adsorption efficiency reduces problem yet.
There are the following problems for adsorbent equipment conventional at present: 1. operating cost is high.Due to replacing or the steam regeneration of adsorbent, cause systematic running cost higher, cause that system operating ratio is low, mostly be decoration device.2. stably reaching standard is difficult.Due to the multi-component competitive Adsorption problem of industry abnormal flavour waste gas, cause that abnormal flavour purification efficiency is not high, it is difficult to ensure the stably reaching standard of abnormal flavour.3. operation management is complicated.Regular replacing adsorbent or heater reclaiming process are difficulty with Automated condtrol, increase difficulty and the workload of operator.4. potential safety hazard.Owing to absorption band is long, traditional absorption-catalytic decomposition process easily occurs that desorption is unstable, safety problem occur.Always there will be adsorbent equipment combustion problem in recent years, gently then injury device, heavy then blast, sum up reason and be mainly gas concentration and undergo mutation, reach burning limit.Gas concentration a kind of situation of undergoing mutation is that gas source condition is unstable, and fluctuation of concentration causes, and be exactly additionally that absorption band is long, and desorption instability occurs that instantaneous concentration transfinites.
Chinese invention patent, publication No.: CN103438467A, date of publication: 2013.12.11, disclose a kind of organic exhaust gas adsorption desorption concentration catalytic combustion device system, including dry filter device, described dry filter device lower end is connected to catalysis burning bed, and described catalysis burning bed right-hand member is connected to spark arrester a, described spark arrester a bottom righthand side is connected to benefit cold blast sliding valve, and described catalysis burning bed lower end is also associated with temperature control valve (TCV).The replacing construction of this invention activated carbon is greatly promoted, decrease the replacing construction of activated carbon, activated carbon can effectively recycle by desorption and regeneration, CO2 and H2O thoroughly it is decomposed into after the catalyzed burning of organic exhaust gas after desorption, non-secondary pollution, system adopts PLC and human-computer interface control operating system, simple to operate, reduces maloperation and is likely to.Its weak point is: first, and in this patent, absorbing process adopts conventional two tower switchings to use, and a tower on-line adsorption, an online desorption of tower, the problems such as absorption band is long, adsorption efficiency is low, desorption is unclean easily occurs when carrying out adsorption operations in adsorption tower.Secondly, desorption gas reuse achieves concentration energy equally, compare traditional adsorption/desorption technique and have very big advantage, but temperature conditions is required higher by catalytic reaction itself, it is typically in 200～450 DEG C, in this patent, after desorption, gas temperature is extremely difficult to catalysis requirement, even if reaching catalytic reaction temperature, organic component decomposes the reaction heat produced and gas temperature can be made to increase further, this problem that can bring two aspects: one is that high-temperature gas itself is dangerous, adsorbent is easily made to catch fire, temperature is more high, danger is more big, because catching fire, the thing making equipment damage completely or to blast is appeared in the newspapers in recent years repeatly；Desorption temperature is typically in less than 260 DEG C on the other hand, and too high gas temperature can cause extra energy waste.
Chinese utility model patent, Authorization Notice No.: CN204601947U, authorized announcement date: 2015.09.02, disclose and a kind of integrate the volatile organic waste gas treatment device that adsorption/desorption catalyzing burns, relate to the process device of volatile organic waste gas in field of environment protection, it is characterized in that: catalytic combustion system is arranged in adsorbent equipment, adsorbent is seated in the chuck of adsorbent equipment and catalytic combustion system formation, the heat adsorbent produced in catalyticing combustion process completes desorption, gas after desorption enters catalytic combustion system and forms circulation, effectively solve respective solely investment in traditional absorption/desorption-catalytic combustion system bigger, energy consumption is high, the problems such as operating cost is high.It is disadvantageous in that: this patent has shared a set of gas piping due to absorption and catalysis, it is achieved the unlatching of demand property, closedown catalytic module difficulty, and cannot realize continuous production；Additionally, this patent occurs aforementioned patent (Chinese invention patent, publication No.: CN103438467A equally, date of publication: 2013.12.11) same problem, even more severe, namely catalytic reaction needs to reach uniform temperature condition, does not occur any firing equipment in this patent；Furthermore, adsorption process is typical exothermic process, and owing to catalytic reaction heat can make adsorbent bed temperature raise by wall, adsorption process is very unfavorable, and therefore this patent through engineering approaches application can run into a lot of problem.
