Working principle:
First by getter device, toxic exhaust gas is recycled, then concentrates and is input in air inlet tubule 13, air inlet
One-way ventilating film 15 in tubule 13 can only allow gas into, do not allow gas to go out, then gas flow out air inlet tubule 13, reach V-type
Left one side of something of air inlet pipe 5, then gas moves upwards, while flow sensor detects the amount of gas, then passes the information on
To control device, control device and then the speed for controlling the movement of electric telescopic rod 9；After gas enters tracheae 3, it is necessary first to carry out
Spray, telescopic rod is shunk first, and pressure is increasing in coolant pipe 4 at this time, and coolant liquid is flowed out by atomizing nozzle, is such as schemed
Shown in 5, then electric telescopic rod 9 extends, and rubber material under the action of water flow of pressure control device 10 starts to deform at this time, allows
Coolant liquid is by being flowed into coolant pipe bottom end at rubber material, since pressure control device 10 is taper, so electric expansion
When bar 9 is shunk, rubber material can be expanded outwardly, and deformation be generated, so that sealing ring and coolant pipe inner wall be allowed preferably to be bonded；
After exhaust gas is sprayed, the impurity being adsorbed by coolant liquid is flowed into air inlet pipe, is then recycled and is filled along solution
Set outflow；Exhaust gas is in tracheae later, and gas, in the top of tracheae, coolant liquid is in the lower section of coolant pipe, so exhaust gas
A tube wall is only spaced with coolant pipe, since tracheae 3 and coolant pipe 4 are made of metal material, so heating conduction is more
It is good, thus realize it is preferably cooling, while the section of tracheae 3 and coolant pipe 4 be it is flat, in order to connecing for bigger cooling
Contacting surface product, furthermore, while be planar as, but inner tube is still circular；
Exhaust gas flows out after spray and cooling from gas outlet, enters in adsorbent equipment, and gas passes through Manual moist stratum
It is had to afterwards by a tiny water droplet tubule 206, water droplet device is regular at this time drips, and drops onto water droplet tubule
In 206, water droplet can just block whole cross section completely, so that gas progress be allowed adequately to contact with water, then water droplet becomes
Sewage is entered in constructed wetland device and is purified, and is flowed into cleaned water tank after purification, and cleaned water tank bottom is inclination
Shape, one end of inclined bottom end connection return pipe, the other end of return pipe connect water droplet device, exhaust gas after water droplet tubule according to
It is secondary to be discharged after over-molecular sieve and activated carbon adsorption device, so as to which VOCs in toxic exhaust gas is comprehensively carried out purification suction
It is attached, thoroughly administer VOCs in toxic exhaust gas.
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.
