Based on the embodiments of the present invention, other embodiments used by those skilled in the art without any creative effort belong to the protection scope of the present invention.
Example 1:
a treatment method for treating waste gas of laboratory animal houses in pharmaceutical enterprises comprises the following steps:
s100, introducing waste gas into a treatment tank;
this treatment tank adopts 304 stainless steel to make, if the treatment tank adopts carbon steel preparation, inside and outside spraying paint anticorrosive treatment, because the paint belongs to the organic matter, under UV ultraviolet beam irradiation, the destruction that the paint anticorrosive coating can be very fast, after the paint anticorrosive coating damaged, carbon steel equipment is very easily rusted and corroded, therefore equipment main part adopts 304 stainless steel preparation.
S200, constructing a microwave field in the treatment tank;
the constructing a microwave field in a treatment tank includes: and a microwave generator is arranged in the treatment tank to generate microwaves and control the microwaves to form a microwave field. The microwave described in this embodiment is an ultra-high frequency electromagnetic wave with a frequency of 0.3-300GHZ, and exhaust gas molecules in the microwave field will make hundreds of millions of violent movements per second following the microwave field, which greatly improves the chemical activity of exhaust gas molecule treatment.
The microwave energy excites the electrodeless UV lamp tube with high performance, high efficiency and long service life to radiate high-energy ultraviolet light mainly comprising 185 NM; 185NM belongs to high-energy C wave band, which can directly crack and destroy odor molecules. Meanwhile, ozone is generated after the reaction with oxygen in the air, the ozone has a strong oxidation effect, and simultaneously under the wave band ultraviolet radiation, the nano titanium dioxide catalyst is activated to react with surrounding water molecules to generate free radical OH < - >, and a molecular chain of waste gas is decomposed through OH < - >.
The nano titanium dioxide catalyst is coated on the multi-layer porous stainless steel metal plate arranged in the treatment tank, and the nano titanium dioxide catalyst is coated on the multi-layer porous stainless steel metal plate, so that the waste gas can be in contact with catalytic decomposition materials in a larger area, and the decomposition of waste gas components is accelerated.
S300, constructing a UV ultraviolet field in the treatment tank;
the building of a field of UV lamps in a treatment tank comprises: and a plurality of UV ultraviolet lamp tubes are arranged in the treatment tank to generate UV ultraviolet light and control the UV ultraviolet light to form a UV ultraviolet light field. The UV ultraviolet lamp tube is an electrodeless UV ultraviolet lamp tube.
At present, UV photoelectric decomposers on the market adopt ballasts and UV polarized lamps.
In terms of energy consumption, the power consumption of each ballast and the UV active lamp tube is between 120 and 150W, the power consumption of the electrodeless lamp tube is 50W, and the energy consumption of the electrodeless lamp tube is less than 1/2 of the active lamp tube; in terms of using performance, the magnetic induction generator excites the vapor mercury and inert gas in the electrodeless lamp tube by using magnetic induction microwave, and the light source without electrodes can not generate blackening phenomenon caused by the problems of electrode oxidation, loss and sealing like other discharge light sources.
The electrodeless light source has the advantages of easy shape change, quick start, stable light emission, high luminous efficiency and the like, and the characteristics of the electrodeless light source cannot be reached by an electrodeless lamp tube. The ballast of the polarized lamp tube belongs to a quick-wear part and is not resistant to high temperature, and the ballast can generate great heat when the lamp tube works, and if the ballast is in a high-temperature environment, the ballast is extremely easy to melt and damage.
S400, introducing the waste gas treated by the microwave field and the UV lamp field into an adsorption tower;
s500, constructing a plurality of activated carbon fiber filter layers in the adsorption tower, and performing adsorption deodorization treatment on the waste gas introduced into the adsorption tower.
The activated carbon fiber filtering layer is formed by carbonizing and activating a fibrous precursor, so that more than 50% of carbon atoms are positioned on the inner surface and the outer surface of the fibrous precursor. Wherein the fibrous precursor is carbonized under the following conditions: the temperature was set to 350-380 ℃ under nitrogen.
More than 50% of carbon atoms are positioned on the inner surface and the outer surface, a unique adsorption structure is constructed, and the fast adsorption and desorption speed and the large adsorption capacity are realized due to the more developed specific surface area and the narrower pore size distribution. The adsorption principle is physical adsorption, the adsorption process has reversibility and is easy to desorb and regenerate, and gas enters an adsorption tower through a pipeline, wherein a plurality of activated carbon fiber filter layers constructed in the adsorption tower are arranged at equal intervals. Equidistant setting is convenient for the segmentation to adsorb the processing to waste gas, has the efficient adsorption to poisonous and harmful gas, and it is fast to adsorb and desorption.

In this embodiment, when the microwave field and the UV lamp field in the treatment tank treat the exhaust gas, the treatment tank is subjected to alternating temperatures of temperature rise and temperature fall, so that the microwave field and the UV lamp field treat the exhaust gas under the alternating temperature conditions of temperature rise and temperature fall.
By applying alternating temperature of temperature rise and temperature drop to the microwave field and the UV ultraviolet lamp field in the treatment tank, the exhaust gas molecules in the microwave field can move more violently, and the chemical activity of the exhaust gas molecule treatment is greatly improved. The alternating temperature of raising and lowering the temperature is mainly used for balancing the improvement of the chemical activity and the safety of the molecular treatment of the waste gas, because a large amount of heat is generated in the waste gas treatment process, if the temperature is too high, the explosion danger exists, therefore, when the temperature in the treatment tank is detected to be too high, the temperature is lowered, and when the temperature is lower, the temperature is raised, so that the waste is treated in the optimal and safe temperature range.
