VOCs concentration detector is provided in air inlet pipe 3, VOCs concentration detector connects control device, auger 5 and rotation Axis 11 is separately connected first motor and the second motor, and control device is also electrically connected first motor and the second motor.
Working principle:
As shown in Fig. 2, exhaust gas is entered in organic solution by the air inlet pipe reduced first, and then enter straight up Escape pipe is capable of increasing the speed that gas enters organic solution using the air inlet pipe of decrement, and then will not return from air inlet pipe, At the same time, Concentration Testing can be come more and then pass information to control dress by the VOCs concentration detector being arranged in air inlet pipe Set, control device and then control auger revolving speed, accelerate the mixing of organic solution and exhaust gas and accelerate exhaust gas rising and from into Tracheae enters the speed in organic solution;
Then exhaust gas is entered in adsorption plant by escape pipe, as shown in Figure 1, during exhaust gas rises, constantly There is adsorbing sphere at the uniform velocity to fall, when adsorbing sphere is fallen, can touch on elastic ring, the frictional layer on elastic ring can be by adsorbing sphere Surface is scratched, so that the adsorption efficiency of adsorbing sphere is improved, and elastic ring also plays the effect of speed limit, in addition, elastic Annular strain, compressed spring, metal bar touches magnet ring switch at this time, so that electromagnetism iron hoop be made to work, is provided in adsorbing sphere Iron ball will be slow whereabouts under the graviational interaction of magnet ring, frictional layer scratches adsorbing sphere table so resistance of the adsorbing sphere in elastic ring The powder in face can drop into powder tube, because absorption vertical tube cross-sectional sizes and adsorbing sphere are almost big, exhaust gas is bound to Contact multiple adsorbing spheres;And absorption ball surface dirt attachment, so adsorption efficiency is higher;The adsorbing sphere of whereabouts drops into down curved Guan Zhong, under the impact that the adsorbing sphere then under the action of driving device, and one by one is fallen, adsorbing sphere can gradually on It rises, and then driving device can will get in adsorbing sphere transport one by one, then fall on from upper bend pipe in absorption vertical tube, in addition, Magnet is provided in ball support, but if adsorbing sphere is larger, attraction is weaker, when adsorbing sphere is smaller, gravitation is larger at this time, It can then be entrusted away by ball under the action of magnet, when ball support moves to one end far from absorption vertical tube, electromagnet indirect Work, the frequency of work of electromagnet and the revolving speed of driving device are directly proportional;Electromagnet adsorbs adsorbing sphere at this time, because electric The attraction of magnet be greater than ball support in magnet, then electromagnet power off, lose magnetism, adsorbing sphere under gravity along The inner wall of driving device moves in dirty bulb, to remake adsorbing sphere;VOCs concentration detector detects the big of concentration The small revolving speed that also will affect rotary shaft.
It is described above;It is merely preferred embodiments of the present invention;But scope of protection of the present invention is not limited thereto; Anyone skilled in the art is in the technical scope disclosed by the present invention;According to the technique and scheme of the present invention and its It improves design and is subject to equivalent substitution or change;It should be covered by the scope of protection of the present invention.
