Description
Technical field
The present invention relates to a kind of emission-control equipment.
Background technology
In the exhaust-gas treatment field, non-thermal plasma trap and biologic treating technique all are the effective technologies of processing organic exhaust gas, if but just there are some defectives in use separately: non-thermal plasma trap is when processing larger molecular organics, often whole molecule can not be broken to single atom fully, and only can form a plurality of micromolecular hydrocarbon fragments.If continue little molecule is further decomposed, need to increase considerably the processing time, namely mean the capacity that need to increase substantially equipment, so just increase the cost of processing waste gas; Utilizing microbial technique to process organic exhaust gas then has certain requirement to handled composition, because processed composition need to could decompose by metabolism with after microorganism contact, therefore the effect processed by biotechnology of the hydrophobic organic matter of molecule is relatively poor greatly.In addition, the effect positive correlation of the density of microorganism and distribution situation and processing waste gas, when micro organism quantity in the system descends or during skewness, result can significantly descend, therefore, the quantity of microorganism and being evenly distributed in the keeping system is the problem that biologic treating technique must solve at any time.
Summary of the invention
Technical problem to be solved by this invention is: a kind of emission-control equipment is provided, and this emission-control equipment combines non-thermal plasma trap and biologic treating technique, is large molecule or the multiple situation of little molecule organic exhaust gas no matter be applicable to.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of emission-control equipment, comprise housing, described housing is provided with air inlet and air outlet, the air channel is communicated with between described air inlet and the air outlet, be disposed with spray washing device, low-temperature plasma generator, blower fan and utilize the biological packing tower of microbial degradation waste gas along wind direction in the described housing, be provided with the switch board of control low-temperature plasma generator, blower fan, spray washing device action in the described housing.
As a kind of preferred scheme, described biological packing tower is provided with the filler for microbial reproduction degraded waste gas, the bottom of described biological packing tower is equipped with for the water tank that replenishes biological inoculum and nutritional labeling, be connected with the water pump by switch board control on the described water tank, be connected with towards the sparge pipe of biologic packing material top of tower on the described water pump.
As a kind of preferred scheme, described spray washing device comprises the shower of the air intake upstream that is installed on low-temperature plasma generator.
As a kind of preferred scheme, described filler is vertically placed.
As a kind of preferred scheme, the filler in the described biological packing tower is cellular filler.
As a kind of preferred scheme, as a kind of preferred scheme, be equipped with between described fan outlet and the biological packing tower and make the uniform air distribution plate of biological packing tower air intake.
After having adopted technique scheme, effect of the present invention is: when processing waste gas, waste gas enters this device from air inlet, under switch board control, waste gas at first is processed into a plurality of little molecules through plasma generator with the large molecule in the waste gas, then enter biological packing tower by the blower fan induced duct, biologic packing material is discharged the little molecular breakdown in the waste gas at last from air outlet.This emission-control equipment combines the advantage of non-thermal plasma trap and biologic treating technique, and is comparatively thorough to exhaust-gas treatment no matter be applicable to be large molecule or the multiple situation of little molecule organic exhaust gas, successful.
Again because described biological packing tower is provided with the filler for microbial reproduction degraded waste gas, the bottom of described biological packing tower is equipped with for the water tank that replenishes biological inoculum and nutritional labeling, be connected with the water pump by switch board control on the described water tank, be connected with on the described water pump towards the sparge pipe of biologic packing material top of tower, therefore can replenish enough biological inoculum and nutritional labelings to the filler in the biological packing tower, and then improve biodegradable efficient.
Because filler preferably adopts cellular structured packing, both can guarantee the contact area of waste gas and biological inoculum again, can guarantee still that behind the biological inoculum amount reproduction Air Flow is unimpeded again; Filler is vertically placed, be convenient to water pump with the liquid in the water tank is logical deliver to the biological packing tower top after, can divide equably to be covered with whole filler.
