detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

The dual-jet washing combined exhaust gas purification system shown in Figure 1 includes a casing, one end of the casing is provided with an exhaust gas inlet 1, and the other end of the casing is provided with a fan chamber 7, and the fan chamber 7 is provided with a centrifugal fan 9, and the fan chamber 7 A gas outlet pipe 8 is arranged on the side, and a spray washing chamber 3 and an ultrasonic mist washing chamber 5 are arranged in sequence from the waste gas inlet 1 to the gas outlet pipe 8 in the casing, and a spray washing tower is arranged in the spray washing chamber 3 , the spray washing tower is provided with a circulating water tank, a gas inlet, a lower packing, a lower spraying pan, an upper packing, an upper spraying pan, a demister layer and a top outlet, an upper spraying pan and a lower spraying pan from bottom to top. The shower plate is connected with the circulating water tank through a water pump, and an atomization generating device 6 is arranged in the ultrasonic mist washing bin 5, and the atomizing generating device 6 can be an ultrasonic atomizer, a high-pressure pump atomizer, etc., and the atomization generating device 6 The biological deodorizing liquid is added, and the biological deodorizing liquid will form liquid droplets close to the sub-nano level. When the equipment starts to work, under the action of the centrifugal fan 9, the exhaust gas enters from the exhaust gas inlet 1, and then passes through the spray scrubber and ultrasonic waves in turn. In the mist washing chamber 5, the final treated clean gas is discharged from the gas outlet pipe 8. When the exhaust gas enters the spray scrubber for treatment, the washing liquid in the circulating water tank is sprayed from the upper spray plate and the lower spray plate of the spray wash tower. The upper and lower layers of packing are mixed with the washing liquid to form a mist-like water film, which rolls continuously under the action of the air flow, and the exhaust gas rotates up in the tower and rubs against the washing liquid water film in the packing, so that the waste gas is absorbed by the water The membrane is fully combined, decomposed and purified. After the washing liquid is continuously sprayed and dropped, it will fall into the circulating water tank and circulate continuously under the action of the water pump to purify the exhaust gas. The taste liquid is a non-toxic and harmless liquid, safe, non-toxic, non-irritating, non-flammable, and non-explosive. The biological deodorizing liquid is atomized by the atomization generating device 6 to form a mist, and diffuses in the ultrasonic mist washing chamber 5. The radius of the droplet is ≤0.5 μm, and the droplet has a large specific surface area and a large surface energy. It is about tens of kilocalories per mole, and the energy of this order is already 1/3-1/4 of the bond energy in many elements. The surface of the solution can not only effectively adsorb the odor molecules in the air, but also change the three-dimensional configuration of the adsorbed odor molecules, weaken the chemical bonds in the odor molecules, increase the instability of the odor molecules, and easily Chemically react with other molecules and the acidic buffer in the deodorizing liquid, and finally generate odorless and non-toxic substances, which can completely purify the exhaust gas. Finally, the clean gas is discharged from the gas outlet pipe 8 under the action of the centrifugal fan 9 , The dual-spray washing combined exhaust gas purification system of the utility model adopts two purification technologies of spray washing and atomization purification, which makes up for the deficiency of a single technology, effectively enhances the purification ability of the purification equipment for polluted gases, and improves the exhaust gas purification. Efficiency. After the atomization purification technology atomizes the biological liquid, it has both physical adsorption and chemical reaction, which significantly improves the cleaning effect and system purification ability. On the other hand, the purification equipment integrates spray cleaning and mist cleaning. The two purification technologies of purification and purification eliminate the need for pipes connecting separate equipment, which not only reduces the space, but also greatly reduces the wind resistance of the equipment, which in turn reduces the required fan power and floor space, and realizes resource conservation.

In addition, a first flow equalizing net 2 is set at the exhaust gas inlet 1, and a second flow equalizing net 4 is set between the spray washing bin 3 and the ultrasonic mist washing bin 5, so that The waste gas from the net 4 can evenly enter the spray washing chamber 3 and the ultrasonic mist washing chamber 5 respectively.

In addition, sound insulation cotton 10 is arranged around the fan chamber 7, and sound insulation cotton 11 is also arranged on the wall of the gas outlet pipe 8. The arrangement of the sound insulation cotton 10 and the sound insulation cotton 11 can resist most of the noise generated by the fan, and the equipment can be realized. It is installed and used in the factory building or workshop, which reduces the restrictions on the requirements of the purification equipment for the installation site.
