The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the invention provides a comprehensive waste gas treatment method which is applied to comprehensive waste gas treatment equipment. The steps involved in the method are described in detail below with reference to fig. 1.
Step 101: and acquiring waste gas to be treated from the gas inlet.
Optionally, the fan obtains the waste gas to be treated from the air inlet at a preset air speed.
In the embodiment of the invention, the waste gas to be treated comprises dust and oxygen O in the air2Nitrogen gas N2Volatile Organic Compounds (VOCs), carbon monoxide CO, ammonia NH3And hydrogen sulfide H2S, ozone O3As well as intolerable odors or gases that create an unpleasant sensation.
Optionally, the waste gas to be treated is obtained from the air inlet at a preset air speed based on the fan.
Illustratively, a fan is installed at an air inlet of the comprehensive waste gas treatment equipment, waste gas to be treated enters the reaction cavity at a preset speed under the action of the fan, and plasma generated between the core wire and the inner wall of the cavity is used for treating the waste gas to be treated under the starting state of the microwave source and the negative high-voltage direct-current power supply.
Step 102: and under the action of a magnetic field and a centrifugal force, the waste gas to be treated is dedusted.
Optionally, a magnetic field is formed between the first magnetic ring and the second magnetic ring; wherein the magnetic field intensity is adjustable; controlling the magnetic field strength based on the distance between the first magnetic ring and the second magnetic ring; and determining the target magnetic field intensity, and dedusting the waste gas to be treated under the action of the target magnetic field intensity and the centrifugal force.
In the embodiment of the invention, the top and the bottom of the waste gas comprehensive treatment equipment are correspondingly provided with the annular magnets, and the top of the reaction cavity is fixedly provided with the magnetic ring. The bottom of the reaction cavity is provided with an adjusting bracket, and the other magnetic ring is fixed on the adjusting bracket. Exemplarily, a user can adjust the support according to actual requirements, so that the height of the magnetic ring at the bottom of the reaction cavity is reached, and the purpose of adjusting the magnetic force is further achieved. The waste gas contains dust, the waste gas enters the reaction cavity from the air inlet through the fan, centrifugal force is generated in the rotation process, particles with density higher than that of the gas are thrown to the wall of the reaction cavity, and further under the action of a magnetic field, once the particles are contacted with the reaction, the particles lose inertia force and fall along the wall by means of momentum of inlet speed and downward gravity, and finally fall in the dust collector.
Step 103: and treating the waste gas after dust removal based on microwaves and plasmas to obtain treated gas.
Optionally, under the action of a high-voltage power supply, plasma is generated between the core wire and the electrode plate; treating the waste gas after dust removal based on microwaves and plasmas to obtain treated gas; wherein the high-voltage power supply is a negative high-voltage direct-current power supply of-30 KV-4 KV.
It should be noted that under the action of the negative high voltage dc power supply, the ionized air generates a large amount of positive ions and negative ions, and the amount of the negative ions is greater than that of the positive ions. Therefore, the negative high-voltage power supply is adopted in the invention, so that the concentration of negative ions can be increased. Meanwhile, under the high-pressure condition, the method can improve the efficiency of the inelastic collision of the high-energy ions and gas molecules or atoms to initiate free radicals, the combination reaction of the free radicals and the gas molecules of the waste gas, increase the discharge time and improve the treatment efficiency of the waste gas.
In the embodiment of the present invention, the microwave refers to an electromagnetic wave with a frequency of 300MHz-300GHz, and is a short for a limited frequency band in a radio wave, that is, an electromagnetic wave with a wavelength of 0.1 mm-1 m. The microwave frequency is higher than the frequency of a general radio wave, and is also generally called "ultra high frequency electromagnetic wave". Microwaves also have a wave-particle duality as an electromagnetic wave. The basic properties of microwaves are generally represented by three characteristics, namely penetration, reflection and absorption. For glass, plastic and porcelain, microwaves almost pass through without being absorbed. The microwave is absorbed into water and food, and the microwave is self-heated. And for metal objects, the microwave is reflected.
Due to the characteristics of microwaves, the microwave transmission system has large propagation loss in air, short transmission distance, good maneuverability and large working frequency width, and is mainly applied to metal waveguides and dielectric waveguides in addition to the millimeter wave technology of 5G mobile communication.
Plasmas are aggregates consisting of charged positive and negative particles (including positive ions, negative ions, electrons, radicals, reactive radicals, etc.), wherein the positive and negative charges are equal in magnitude, so called plasmas, which are macroscopically electrically neutral. The plasma, which is composed of electrons, ions, radicals, and neutral particles, is a conductive fluid and generally maintains electrical neutrality.
In the embodiment of the invention, the working principle of waste gas treatment is as follows: gas molecules in the air are ionized under the action of the negative high-voltage direct-current power supply 4 to generate a large number of particles such as electrons, active free radicals, atoms, excited molecules and the like, and the particles have high reaction activity. Under the action of high voltage direct current, the generated high-energy electrons and gas molecules or atoms in the air generate inelastic collision to initiate free radicals, and the free radicals and waste gas molecules are combined to react, so that the aim of evolution and treatment of waste gas is fulfilled.
Step 104: and discharging the treated gas from the gas outlet.
