Description
Technical field
The present invention relates to waste gas treatment equipment technical field, refer in particular to a kind of purifying processing device of industrial organic exhaust gas.
Background technology
Along with the development of society, the environmental pollution that the activity of the mankind causes is on the rise.Current atmosphere quality worsens further, and the multiple gases pollutant that the operations such as ever-increasing industrial waste gas, vehicle exhaust and house decoration produce has started the health of the serious threat mankind.Therefore countries in the world are all taking measures to control air pollution.Except formulating strict discharge standard, in recent years the research of waste gas processing method was also made some progress.
Volatile organic waste gas is industrial organic exhaust gas pollutant the most common, it is mainly derived from: the waste gas that oil, chemical industry are discharged, and the organic solvent of the industry such as paint, papermaking, mining, coating, weaving, metal plating discharge, volatile organic waste gas causes very large harm for environmental quality, animal and plant growth and the healthy of the mankind.In the volatile organic waste gas of China is administered, all kinds of new technique obtains deep research and development and extensive use.
At present, in the volatile organic waste gas of China is administered, conventional Treatment process mainly contains: absorption method, absorption process, Production by Catalytic Combustion Process, condensation method etc., but above-mentioned Treatment process limitation is in actual applications comparatively large, the general improvement being only suitable for middle and high concentration or little air quantity volatile organic waste gas.For the improvement of the volatile organic waste gas of low concentration or Wind Volume, and effect is very faint.Therefore, in the research of China's volatile organic waste gas Treatment process, the Innovation and reform for prior art should be noted.
For this reason, united states, japan and other countries adopts dielectric barrier discharge DBD to produce non-equilibrium plasma in investigation and application field administers large discharge industrial waste gas, has carried out extensive work.In China, plasma (being particularly the high efficiency degraded of core with double-dielectric barrier discharge) and the investigation and application of photocatalysis technology are also deepening continuously in recent years; One of focus becoming research both at home and abroad for the treatment of all kinds of pernicious gas by lower temperature plasma technology, compared with other abatement of noxious gases technology, plasma method has the features such as handling process is short, efficiency is high, energy consumption is low, applied widely.Lower temperature plasma technology advantage in gaseous contaminant improvement is remarkable, and it has become current study frontier, also the just increasing improvement for gaseous contaminant.
Therefore, based on above-mentioned existing industrial organic exhaust gas to the pollution of environment, namely applicant gives special concern to correlation technique from the date of its birth founding always, photocatalyst technology and product, the application and research of engineering is in quite advanced level both at home and abroad, particularly we be core with the photocatalysis technology of double-dielectric barrier discharge and advanced person " low-temperature plasma+composite photocatalyst industrial waste gas purification device " has obtained significant effect in improvement large-scale industry waste gas, obtain high evaluation and the accreditation of the users such as the national parties concerned and large chemical complex, fill up the technological gap of China in industrial large discharge VOCs treatment, facts have proved that low-temperature plasma+composite photocatalyst is a kind of advanced Treatment process of real high-efficiency low energy consumption.
Summary of the invention
The object of the invention is to the purifying processing device providing a kind of industrial organic exhaust gas for the deficiencies in the prior art, the purifying processing device of this kind of industrial organic exhaust gas solves existing industrial organic exhaust gas and discharges problem that is not up to standard, pollution _ _ environment.
For achieving the above object, the present invention is achieved by the following technical solutions:
A purifying processing device for industrial organic exhaust gas, comprises the high-energy ion purifier, photocatalyst cleaning equipment, the spray purification tower that connect in turn, and high-energy ion purifier connects waste gas and enters pipe.
The external active carbon adsorber of described spray purification tower.
The external air-introduced machine of described active carbon adsorber.
The external discharge drum of described air-introduced machine.
Usually, the method for administering organic exhaust gas comprises absorption method, absorption process, photocatalytic method, plasma for purification method, oxidizing process, combustion method, shelters, dilutes diffusion method and bioanalysis etc.According to composition and the concentration feature of this industrial organic exhaust gas especially volatile organic waste gas, this patent adopts the technique purification thinking of multiple process for purifying tandem compound, that is: first utilize high energy particle purification techniques, the organic odoriferous material in waste gas is carried out oxidation Decomposition; Next, after utilizing photocatalyst purification techniques article on plasma to decompose, waste gas is thoroughly degraded into CO2 and H2O, finally utilizes spray purification tower, adopts spray medicament and dosing method, the main inorganic gas removed in waste gas, thus realizes final purification qualified discharge.
Nano level silver ion and diameter is adopted to be the titanium dioxide of 7nm in photocatalyst cleaning equipment, the metallic nickel made with foam pattern is embedded in online by the mode that spraying and high speed are injected, under special ultraviolet source irradiation, make to enter " hole-electron " that in special photocatalysis chamber, pernicious gas and photocatalysis produce to and hydroxyl free radical etc. produce physics--chemical reaction, is oxidized, decomposes all kinds of pernicious gases not yet degradable after low-temperature plasma effect.
Spray packed tower, as the main equipment of inorganic constituents in purifying malodorous gas, has the advantages such as water distribution is even, tower inner member is few, running resistance is little, contact area is large, gas-liquid mass transfer is effective.Its technical characteristic is mainly reflected in following several aspects: 1. the ball filler of PP material or Pall ring filler are to increase gas liquid interfacial area; 2. corrosion resistant feeding spraying pump, has enough spray liquid-gas ratios; 3. corrugated plating is installed except water packing at the rear portion of spray purification tower, to reduce the loss of spray liquid;
4. the main component of spray liquid is the mixed liquor of clorox and NaOH; 5. automatic medicine adding apparatus is set, according to the pH value of cyclic water tank and the change of ORP value, automatically regulates the operation of dosing pump.
Beneficial effect of the present invention is: waste gas is by high-energy ion purifier, and the odor molecules generation chemical reactions such as contained methyl mercaptan, methyl sulfide and hydrogen sulfide, generate water and other nonpoisonous and tasteless molecules, thus realize catharsis; Next, after utilizing photocatalyst cleaning equipment article on plasma to decompose, waste gas is thoroughly degraded into CO2 and H2O, finally utilizes spray purification tower, adopts spray medicament and dosing method, the main inorganic gas removed in waste gas, thus realizes final purification qualified discharge.
