Solid phase adsorption module further includes active-carbon bed 18 be set in adsorption chamber 15, and active-carbon bed 18 in adsorption chamber 15
Between the upper and lower every setting multilayer.In real work, exhaust gas enters adsorption chamber 15 from the bottom of adsorption chamber 15, and is gradually increasing；Herein
In the process, exhaust gas will will carry out activated carbon adsorption to exhaust gas by active-carbon bed 18, active-carbon bed 18, to effectively remove exhaust gas
In impurity.
Meanwhile adsorption module further includes the biofilter 19 being arranged side by side near adsorption chamber 15, biofilter 19 passes through
Pipeline is connected with above-mentioned adsorption chamber 15, and the gas outlet of adsorption chamber 15 is located at its near top, and the air inlet position of biofilter 19
In its bottom；After exhaust gas enters biofilter 19, the organic matter in exhaust gas will degrade again in biofilter 19
Reaction.In fact, to avoid equipment volume excessive, the 19 volume Miniaturizable of biofilter, while can be opened and closed in the setting of cabinet 1
Maintenance mouth 20；By the maintenance mouth 20, staff can regularly replace the filler in biofilter 19.
Above-mentioned exhaust pipe 3 is set to the top of biofilter 19, and 1 inner wall of cabinet is also solid at the air inlet of exhaust pipe 3
Surely there is drying unit 21, which can be electric heater；Meanwhile exhaust pipe 3 is also connected with air blower 22.In practical work
In work, the exhaust gas after biological adsorption is completed in biofilter 19 will enter drying unit 21, and pass through exhaust pipe 3 after being oven-dried
Cabinet 1 is discharged.
The working principle of the present embodiment is: on the one hand, inhaling mould using spray module, electro-catalysis module, photodissociation module, solid phase
Block and biofilter 19 successively spray exhaust gas, electro-catalysis, photodissociation, solid phase adsorption and biological adsorption, realizes to exhaust gas
Multiple purifying processing, not only facilitates reduction energy consumption, moreover it is possible to exhaust-gas treatment effect be greatly improved.On the other hand, will spray module,
Electro-catalysis module, photodissociation module, solid phase adsorption module and biofilter 19 are integrated into same equipment simultaneously, and whole equipment is high
Spend it is integrated, facilitate shorten the exhaust-gas treatment period, so that exhaust treatment efficiency be greatly improved.
Embodiment two:
Referring to attached drawing 2, a kind of waste gas processing method, comprising the following steps:
S1, exhaust gas is collected.
S2, spray: spray process is carried out to exhaust gas.After the completion of gas sampling, exhaust gas is passed through spray using air inlet pipe 2
Room 4；In spray chamber 4, acid-base neutralization reaction will occur with exhaust gas for the absorbing liquid that spray thrower 5 sprays out, and effectively remove useless
The particulate matters such as dust in gas, realize the preliminary purification of exhaust gas.
S3, electro-catalysis: electro-catalysis is carried out by exhaust gas, the organic matter in oxidation and degradation exhaust gas.Complete spray process
Afterwards, exhaust gas will enter electro-catalysis room 6 by the first connecting tube 6；In electro-catalysis room 6,9 continuous discharge of high-voltage pulse generator,
And electro-catalysis is carried out to the organic matter in exhaust gas, bring it about oxidation, degradation reaction.
S4, photodissociation: disinfection by ultraviolet light is carried out to exhaust gas.When exhaust gas enters photolysis cell 11 by the second connecting tube 13；In light
It solves in room 11, ultraviolet radiator 12 can effectively kill the microorganisms such as bacterium in exhaust gas, to realize further purification to exhaust gas.
S5, solid phase adsorption: activated carbon adsorption processing is carried out to exhaust gas.When exhaust gas enters adsorption chamber by third connecting tube 16
After 15, active-carbon bed 18 in adsorption chamber 15 will carry out solid phase adsorption to exhaust gas, effectively remove the impurity in exhaust gas, purify again
Exhaust gas.
S6, biological adsorption: exhaust gas is purified using biofilter 19.In the completed after solid phase adsorption, exhaust gas will be gone successively to
Biofilter 19；In biofilter 19, the organic matter in exhaust gas is by further occurrence degradation reaction, to further increase useless
The treatment effect of gas.
S7, exhaust gas is dried, and discharged it.Exhaust gas after completing biological adsorption will enter drying unit
21, and be discharged after completing to be dried through exhaust pipe 3, and then complete entire waste gas treatment process.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
