Description

A kind of chemical industry waste water station foul smell is collected and processing system
Technical field
The utility model is related to Organic Waste Gas Pollution Treatment process fields, are specifically related to a kind of include collecting and processingization The system of industrial and commercial bank's industry waste water station foul smell, the especially process combination of the odor collection system of front end and end.
Background technology
Existing waste water station foul smell is generally uncontrollable discharge, but as Environmental improvement aspect is increasingly paid attention to, greatly Gas administer require be increasingly stringenter, waste water station foul smell (VOCs) also need through collection, handle it is up to standard after could discharge.Currently, Common VOCs administering methods mainly have bioanalysis, chemical washing method, combustion method, vegetation water absorption, photochemical catalytic oxidation, low temperature etc. Ion body technique etc..
1. bioanalysis
Bioanalysis is a kind of more treatment process of Recent study, is mainly degraded using the metabolic activity of microorganism VOCs and odorant are allowed to be oxidized to nontoxic final product.The most prominent advantage of this method is that purifying low-concentration is organic It is with obvious effects when pollutant, processing cost is cheap, basic non-secondary pollution, but that there are vapour locks is big, degradation rate is slow, equipment volume Huge, vulnerable to pollution object concentration and temperature influence, and the method is only applicable to the processing of hydrophily and easily biological-degradable substance, To the processing of hydrophobicity and recalcitrant substance, there is also certain difficulty.
2. chemical washing method
Currently, chemical washing deodorization technology refers mainly to soda acid purification techniques, i.e., by acid-base property difference VOCs gases by washing It washs tower and is washed with bronsted lowry acids and bases bronsted lowry and chemically reacted.But washing can only remove the VOCs substances that solvable or part is slightly soluble in water;Acid Wash the alkaline matters such as removable amine;Alkali cleaning is then suitable for the acidic materials such as removal lower fatty acid.
3. combustion method
Combustion method mainly has directly burning (TO), heat-accumulation combustion (RTO) and heat-storage catalytic burning (RCO) etc., main to be applicable in In the exhaust-gas treatment of small air quantity high concentration, combustion method is thorough to exhaust gas constituents processing but high to exhaust gas constituents security requirement, fortune Row combustion gas or electric energy consumption are larger, and the flue gas of generation needs after-treatment.Moreover, burning when containing chlorinatedorganic will produce hydrogen chloride corruption Erosion problem, especially at high operating temperatures, the corrosive nature of hydrogen chloride greatly enhance, and not only exist to pipeline and corrode, more seriously Be the corrosion that can cause incinerator.There are the potential dangers of explosion, especially effumability fuel gas when burning, if reaching Its explosion limit meets open fire and is then possible to set off an explosion.
4. vegetation water absorption techniques
Extracting solution of the working solution of VOCs processing from more than 360 kinds of natural tree, flowers and plants, it is multiple through special micro-emulsion technology With into.Pointedly different model working solution can be selected to be matched according to the different characteristic of odor source.Contain in vegetation water A variety of high chemism effective ingredients can both be atomized into the liquid that grain size is less than 0.04mm through dedicated control device and atomising device The low concentration VOCs of drop removal site space, and the mode centralized collection processing high concentration VOCs of scrubbing tower can be used.It is main Principle is to eliminate stink by a series of physical such as absorption, absorption, decomposition, chemical combination, catalysis oxidation, polymerization, chemical reaction mechanism It is allowed to become nontoxic, tasteless molecule, is effective deodorization, the ideal environment-friendly products to eliminate the unusual smell.Natural plant liquid removes VOCs, because of it The method of advanced technology and science can truly realize green, environmental protection, health both not interfered with, to environment It will not cause secondary pollution.
5. photocatalysis oxidation technique
Photochemical catalytic oxidation is that catalytic action occurs under the action of illumination, and photocatalysis oxidation reaction is with semiconductor and air It is CO by organic matter degradation using light as energy for catalyst2And H2O.In photocatalysis oxidation reaction, existed by ultraviolet light Nano-TiO2Electron-hole pair is generated on photochemical catalyst, generation is reacted with the moisture of adsorption and oxygen has strong oxidizing property Hydroxyl radical free radical (OH) and Superoxide anion free radical (O2), can various waste odour-gas bodies photochemical catalytic oxidation effect Under be converted to carbon dioxide, water and other nontoxic substances, while having effects that deodorization, disinfection, sterilization.
6. lower temperature plasma technology
Low temperature plasma is the 4th state of substance after solid-state, liquid, gaseous state, when applied voltage reaches putting for gas When piezoelectric voltage, gas is breakdown, generates the mixture including electronics, various ions, atom and free radical.In discharge process Although electron temperature is very high, heavy particle temperature is very low, and low-temperature condition is presented in whole system, so referred to as low temperature plasma. Low-temperature plasma degradation pollutant is made using the pollutant in these high energy electrons, free radical isoreactivity particle and foul smell With, so that contaminant molecule is decomposed within the extremely short time, and occur it is subsequent it is various reaction to reach degradation of contaminant Purpose.
Though various treatment technologies as described above are very ripe, chemical industry waste water station VOCs ingredients and its reaction Complexity, volatile materials can not specifically determine ingredient and concentration, and VOCs treatment effects are handled using single a certain technology Emission request cannot be reached, need to carry out kinds of processes combination to handle VOCs.Therefore one kind is needed to overcome the organic foul smell of wastewater disposal basin Uncontrollable discharge, the problem of can not effectively collecting and general photooxidation catalytic unit generate in excessive ozone discharge to air The chemical industry waste water station foul smell of problem is collected and processing system.
