First embodiment
Fig. 1 is refer to, embodiments of the invention provide a kind of bio-trickling filter experimental system 100, and it includes bio-trickling
Tower body 110, delivery pump 120, stripping bottle 130, surge flask 140 and nutrient solution measuring pump 150.
When using Biochemical method waste gas, bio-trickling filter body 110 is that the reaction of whole exhaust-gas treatment occurs
Device.When waste gas is entered into inside bio-trickling filter body 110 by conveyance conduit, due to being filled out filled with biology inside it
Material, effectively can be reacted with waste gas, especially organic exhaust gas, so as to be degraded to it, generate nontoxic product
Thing so that waste gas is changed into gas up to standard such that it is able to be discharged into air.
Waste gas enters tower body from the air inlet of bio-trickling filter body 110.Preferably, air inlet is arranged at bio-trickling filter
At the bottom of towe of body 110 such that it is able to during waste gas is moved upwards, reaction is sufficiently carried out.In bio-trickling filter sheet
Inside body 110 by the degraded of microorganism after, discharged from the tower top of bio-trickling filter body 110.
It should be noted that the shape of bio-trickling filter body 110 is not limited.Cylindrical shape or length can be selected
Cube shape.The material of bio-trickling filter body 110 is also not limit, and can select stainless steel material or other alloys
Material.
Fig. 2 is refer to, in the present embodiment, bio-trickling filter body 110 includes some.Specifically, bio-trickling
Tower body 110 from tower top to bottom of towe at be followed successively by spray liquid part 111, biologic packing material part 112, biological nutrient liquid storage part
113。
Further, biologic packing material part 112 includes multiple packing layers, and each layer of packing layer is provided with compartment 114.
Compartment 114 is internally provided with bio-carrier, and bio-carrier is multistage.Bio-carrier is for attached microbial therefore raw
The quantity of thing carrier should be ensured that in a rational scope.Very few bio-carrier, it is impossible to enough ensure enough microorganisms
To adhere to, so as to the treatment effect of waste gas during subsequent operation can be influenceed.Excessive bio-carrier can cause the waste of resource again,
The cost of whole equipment can also be increased simultaneously.Preferably, in the present embodiment, bio-carrier selects 2~5 grades, so can not only
Enough ensure that enough bio-carriers carry out attached microbial so that reach good exhaust-gas treatment effect, also do not result in resource
Waste, the cost economical rationality of whole equipment.
From the above, bio-carrier selection composite.Composite has the performances such as good biology, mechanics, machinery.
And as the composite of bio-carrier, do not require nothing more than with good mechanical strength, case hardness, also requirement can not be damaged micro-
Biology, so traditional metal material etc. cannot meet.Preferably, in the present embodiment, bio-carrier selection PVC, ABS etc. are hard
Material sets up the fibrous materials such as polypropylene, polyamide on its surface as skeleton by the processing method of composite.It is this
Composite can not only ensure bio-carrier required for mechanical strength and hardness, it is also possible to ensure the attachment band of microorganism
Border.
It should be noted that in other preferred embodiments, each layer of packing layer is multiple comprising multiple compartments 114
Compartment 114 is in parallel.
Further, at the top of each compartment 114 of each packing layer and each packing layer each compartment 114
Bottom at be provided with valve.By adjusting the switch of the bottom of each compartment 114 or the valve at top, so as to be formed
Different gas flow passages, exhaust-gas treatment is carried out so as to be formed with various modes.Specifically, according to the concentration and class of waste gas
Type, can select appropriate number of compartment 114 to allow waste gas to pass through such that it is able to ensure when needed, to open corresponding
The valve of the top and bottom of compartment 114, and then realize each compartment 114 and can individually carry out exhaust-gas treatment.This
The setting of sample, the compartment 114 that can be needed according to the concentration of waste gas and type selecting be processed, it is to avoid the wave of the energy
Take, also achieve specific aim treatment waste gas, improve the efficiency of exhaust-gas treatment.
Fig. 2 is continued referring to, further, in the present embodiment, spray liquid part 111 is communicated in nutrient solution measuring pump
150 such that it is able to ensure enough pressure and power, nutrient input is delivered to inside bio-trickling filter body 110.
It should be noted that in other preferred embodiments, each packing layer is provided with spray liquid device, such energy
It is enough to ensure, the nutrient solution required for each layer of growth of microorganism.And can be according to each layer of microorganism specifically to battalion
The need for nutrient solution, there is provided the nutrient solution required for it, the waste of resource is not resulted in not only, and can be targetedly micro-
Biology provides nutrient solution.
Biological nutrient liquid storage part 113 is located at position at the bottom of towe of bio-trickling filter body 110.So as to preferably
Adapt to the demand of technique productions.It is constantly defeated upwards after waste gas enters tower body from the air inlet of bio-trickling filter body 110
Send, by the degraded of microorganism after, discharged from the tower top of bio-trickling filter body 110.Certain microorganism is now consumed,
Appropriate nutrient input is delivered at microorganism by nutrient solution measuring pump 150 from bottom of towe again, it is ensured that pure, the guarantor of nutrient solution
The smooth growth of microorganism is demonstrate,proved.
Fig. 1 is refer to, the air inlet of bio-trickling filter body 110 is communicated in the gas outlet of surge flask 140, surge flask 140
Air inlet be communicated in stripping bottle 130 gas outlet, stripping bottle 130 air inlet be communicated in delivery pump 120.
Stripping bottle 130 is arranged at after delivery pump 120, when the air conveying that delivery pump 120 will be mixed with waste gas is come in, this
When, in air in addition to containing organic exhaust gas, also containing other gases, by setting organic matter stripping bottle 130, will can have
Machine waste gas is individually caught out, and then organic exhaust gas are conveyed.Such setting, enables to follow-up biodegradation more
Plus ground is precisely, the efficiency of later use microbial degradation organic exhaust gas can be effectively improved, so as to improve the effect of whole device
Rate.
Additionally, the setting of surge flask 140, can effectively prevent from conveying the gas come in by suck-back by delivery pump 120
Return in delivery pump 120, the security of the operation of whole bio-trickling filter experimental system 100 is further ensured, so as to be follow-up
Technological process provide and ensure, and then improve efficiency.
Specifically, the mixed gas containing organic exhaust gas are delivered into come by stripping by waste gas delivery pump 120 first
Bottle 130 is processed it, catches organic exhaust gas, continues to be fed forward, and now reaches surge flask 140, continues to be advanced forward into
In bio-trickling filter body 110, that is, complete the course of conveying of waste gas.
