Specifically, as shown in fig. 2, the alkali washing device 1 includes a first flow washing tank 10, a first packing layer 1000, a first circulating pump 13, a first spray header 11 and a circulating water tank 12, the first packing layer 1000 is disposed in the first flow washing tank 10, of course, a first supporting plate 100 for mounting and placing the first packing layer 1000 is disposed in the first flow washing tank 10, a cleaning solution is disposed in the circulating water tank 12, the circulating water tank 12 is communicated with the first flow washing tank 10 through a pipeline, the first spray header 11 is disposed above the first packing layer 1000 and is communicated with the circulating water tank 12, and the first circulating pump 13 is disposed between the first spray header 11 and the circulating water tank 12 so as to extract the cleaning solution in the circulating water tank 12 to be sprayed on the first packing layer 1000 through the first spray header 11. The cleaning solution is NaOH solution or lime water, when the NaOH solution is used as the cleaning solution, hydrogen sulfide and ammonia gas have good removal effect, and the two substances can be dissolved in water and can react.
The waste gas that produces the instant noodle factory manufacturing instant noodle lets in first flowing and washes pond 10, utilizes first circulating pump 13 to pass through the pipeline with the washing liquid in the circulating water tank 12 and extracts first shower head 11, and first shower head 11 sprays the washing liquid on first packing layer 1000, and in first flowing and washing pond 10, gaseous obtaining after through first packing layer 1000 purifies and enters into next exhaust-gas treatment process, and the washing liquid sprays and gets into in circulating water tank 12 behind first packing layer 1000. The first packing layer 1000 is a gas-liquid mass transfer medium and is mainly used for ensuring that gas is fully contacted with and fully reacts with cleaning fluid.

The waste gas treated by the alkali liquor washing device 1 enters an electrostatic oil fume purifier 2, and a multi-stage high-voltage electrostatic field consisting of a cathode and an anode is arranged in the electrostatic oil fume purifier 2. The cathode is a linear electrode with small curvature radius, the curvature radius of the anode is large, direct current high voltage is added between the two electrodes, gas can be ionized to emit electrons to become positive ions and negative ions under the action of external energy, the gas passes through an electric field with large difference of each item of the curvature radius, when the electric field intensity is high enough, avalanche effect can occur to stubborn body ions near the surfaces of the electrodes, the recombination process is particularly violent, the distance between the surfaces of the two electrodes is gradually increased, the electric field intensity is rapidly reduced along with the increase of the distance between the surfaces of the two electrodes, the ion moving speed is reduced, the gas space is not broken down to cause the breakdown of the whole space, and in a high-voltage ionization region, the uneven electric field causes corona discharge.
The flue gas passes through the high-voltage ionization region, because the high-voltage electric field continuously generates corona discharge, a large number of negative ions move from the cathode to the anode under the action of the electric field, so that flue gas particles are charged, the flue gas particles adsorbed on the anode plate lose charges, the separated flue gas is gathered into oil drops, and the oil drops are settled by gravity and fall into the bottom of the device for centralized collection. Meanwhile, in an ionization region, negative ions are mainly oxygen ions, after the oxygen ions capture oil fume particles, the oil in cooking is mainly animal and plant unsaturated fatty acids, and the molecular formula of the main component is C18H14O2The negative ions combine with H, C to form H2O、C、CO2And other harmless substances are discharged through the airflow. The fragrant smell in cooking is also composed of hydrocarbon, and due to the combination of oxygen ions, part of fume smell can be converted into odorless gas to be discharged, so that part of fume smell in cooking is eliminated in a limited way.
Because the waste gas after the alkali lye washing belongs to the gas-liquid mixture state, in order to avoid influencing the next processing workshop section, after the waste gas gets into electrostatic oil smoke clarifier 2 and handles, must remove most steam in the gas through dewatering device 3. The dewatering device 3 selects a demister, when gas containing mist flows through the demister at a certain speed, due to the inertia impact effect of the gas, the mist collides with the corrugated plate of the demister, the gathered liquid drops are larger than the gravity generated by the mist, and when the resultant force of the rising force of the gas and the surface tension of the liquid is exceeded, the liquid drops are separated from the surface of the corrugated plate, so that the dewatering effect is achieved, most of water in the waste gas is removed, and the humidity is removed.
The exhaust gas treated by the above-mentioned process is introduced into the deodorizing and washing device 4 through a pipe, as shown in figure 3, the deodorization washing device 4 comprises a second washing tank 40, a second packing layer 4000, a second circulating pump 43, a second spray header 41 and a liquid storage tank 42, wherein the second packing layer 4000 is arranged in the second washing tank 40, of course, the second washing tank 40 is provided therein with a second supporting plate 400 for mounting and placing a second packing layer 4000, the liquid storage tank 42 is filled with a deodorizing liquid, the deodorizing liquid is NewBio-C deodorizing liquid, the liquid storage tank 42 is communicated with the second flow washing tank 40 through a pipeline, the second spray header 41 is arranged above the second packing layer 4000 and communicated with the liquid storage tank 42, the second circulation pump 43 is disposed between the second spray header 41 and the liquid storage tank 42, so as to extract the deodorizing liquid in the liquid storage tank 42 and spray the deodorizing liquid on the second filler layer 4000 through the second spray head 41.
Specifically, waste gas enters the second washing tank 40, the deodorization liquid in the liquid storage tank 42 is pumped to the second spray header 41 through the pipeline by the aid of the second circulating pump 43, the deodorization liquid is sprayed on the second packing layer 4000 by the second spray header 41, in the second washing tank 40, gas water is purified after passing through the second packing layer 4000 and enters the next waste gas treatment process, and after the deodorization liquid is sprayed on the second packing layer 4000, the deodorization liquid flows through the second packing layer 4000 and enters the liquid storage tank 42. The second packing layer 4000 is also a gas-liquid mass transfer medium, and is mainly used for ensuring that gas is fully contacted with the deodorization liquid and fully reacts.
Because the New Bio-C deodorizing liquid contains deodorizing particles, the surfaces of the deodorizing particles can not only effectively adsorb peculiar smell molecules in the air, but also promote the change of the spatial configuration of the adsorbed peculiar smell molecules; in addition, the deodorizing particles can provide electrons for odor molecules to accelerate the reaction with the odor molecules; the surfaces of the deodorizing particles can also adsorb odor molecules in the air, and the three-dimensional structures in the odor molecules are changed and become unstable; meanwhile, odor molecules adsorbed on the surfaces of the deodorizing particles can also react with oxygen in the air.
The relevant reactions are as follows:
acid-base reaction, for example, the deodorized particles contain trace alkaloid which can react with acidic odor molecules such as hydrogen sulfide. Unlike the common acid-base reaction, the common base is toxic, non-edible and non-biodegradable, and the high-purity plant extract can be biodegraded and is non-toxic.
Catalytic oxidation reactions, such as hydrogen sulfide and other acidic gases, typically do not react with oxygen in the air. But can react with oxygen in the air under the catalysis of the plant extract.
Taking the reaction of hydrogen sulfide as an example, the relevant reaction formula is as follows:
R-NH2+H2S→R-NH3++SH-
R-NH2+SH-+O2+H2O→R-NH3+SO4 2-+OH-
R-NH3++OH-→R-NH2+H2O
the oxidation-reduction reaction, such as formaldehyde, has oxidation property, and the effective molecules in the plant liquid have reduction property. They can be reacted directly. Reaction with formaldehyde and ammonia, the relevant reaction formula is as follows:
HR-NH2+HCHO→R-HN2+H-C＝CO2+H2O
R-NH2+NH3→R-NH2+N2+H2O
through the series of reactions, the components which are easy to dissolve in water in the waste gas are removed, and the odor concentration of the waste gas can be effectively reduced.
