Definition of micro nano bubble high gravity dynamic oxidation technology

Micro nano bubble high gravity dynamic oxidation technology is an advanced oxidation technology applied in waste gas treatment. It is an integrated design of water collection, electricity and gas (micro nano bubble device, oxidation medium, high gravity dynamic bed), automatic control system, fan, etc. The whole system is compact in structure, beautiful in appearance and less in land occupation. It is suitable for new construction or upgrading of various waste gas treatment.

High gravity dynamic working principle:

The waste gas is introduced into the outer chamber of the rotor from the tangential direction through the inlet pipe, and enters the packing from the outer edge of the rotor under the action of gas pressure. The super oxygen micro nano bubble water inlet pipe is introduced into the rotor cavity for uniform spraying. The liquid entering the rotor is acted by the packing in the rotor, the circumferential velocity increases, and the centrifugal force will push it to the outer edge of the rotor. In this process, the liquid is dispersed and broken by the packing, forming a huge and constantly updated surface area, and the tortuous flow passage intensifies the renewal of the liquid surface. In this way, excellent mass transfer and reaction conditions are formed in the rotor. The liquid is thrown to the shell by the rotor and then leaves the overweight machine through the liquid outlet pipe. The gas leaves the rotor from the center of the rotor and is led out from the gas outlet pipe to complete the mass transfer and reaction process.

When the waste gas enters the high gravity bed and forms a gas-liquid mixture with micro nano bubble water, it passes through the rotating wheel of the high gravity bed and enters the abdominal cavity of the high gravity bed. Under the action of the high gravity field, the mass transfer and heat transfer efficiency of the fluid in the high gravity field can be greatly improved, The high concentration of ions accumulated on the interface will release the accumulated chemical energy at a time, which can stimulate the generation of a large number of hydroxyl radicals with ultra-high redox potential. The super oxidation generated by hydroxyl radicals can degrade the pollutants in the exhaust gas, and solve the problems of particles, dust, volatile organic compounds (v0c), inorganic compounds, non methane hydrocarbons, hydrogen sulfide, odor, etc Ammonia, mercaptan, phenol, etc.

Characteristics of contact technology of micro nano bubble super gravity gas-liquid mass transfer

1: In micro nano bubble super gravity dynamic reactor, the effective gravity of liquid will be tens or even hundreds times of that of traditional scrubber. The point of gas-liquid two-phase is greatly improved, which makes it possible to enhance the relative velocity between gas and liquid by increasing the gas-liquid velocity, so as to quickly strengthen the mass transfer reaction efficiency of gas-liquid two-phase.

2: In the micro nano bubble hypergravity field, the relative sliding velocity of gas-liquid two-phase fluid is very large, and the huge shear stress overcomes the surface tension of the liquid, and makes the liquid extend out of a large contact interface. The water film becomes thin and has little liquid holding phenomenon. The liquid is rapidly dispersed, highly turbulent The mass transfer process is greatly enhanced by the contact between the gas and the gas in the bending channel of the filler with strong mixing and rapid interface renewal.

4: The cutting particle size range of the super gravity equipment is between 0.02-0.3um, and the capture efficiency of particles above 3um is 95-100%;

5: Small volume and small land occupation not only reduce cost, but also reduce impact on environment;

6: The gas-liquid mass transfer efficiency is high and the resistance of the equipment is small;

7: It can also cool down, dust and remove VOCs gas without any potential safety hazards;

8: It can be matched with any waste gas treatment equipment as pretreatment equipment to form an integrated treatment system.

9: The equipment is easy to operate, and it is convenient to operate, maintain and repair;
