Description

Air purifying device
Technical Field
The invention belongs to the field of environmental protection, and particularly relates to a device capable of purifying waste gas generated in a paint spraying workshop of a factory.
Background
In the process of spraying, airing and drying a steel structure, a solvent and a diluent in the coating can generate a large amount of toxic substances such as benzene, toluene, xylene, ketone, ester and the like, the coating has irritant taste, if the coating is not effectively treated, organic waste gas generated by volatilization is emitted into the air, and the waste gas can cause nausea, vomiting, allergy, mental confusion, chronic or acute poisoning after entering a human body through a respiratory tract and endanger the physical health of workers, so that fewer and fewer workers are involved, the loss is serious, the pollution of production and the external environment is aggravated, and the serious influence is caused on the atmospheric quality.
Disclosure of Invention
The invention provides a waste gas purification device, which aims to purify the air in a workshop, reduce the discharge of toxic gas and reduce the pollution to the environment.
A waste gas purifier is composed of waste gas collector, coarse-effect purifier, activated carbon purifier, photocatalytic purifier and exhaust pipe. Waste gas collection device connects and imitates purifier roughly, imitates purifier roughly and connects active carbon purifier, and active carbon purifier connects light catalytic purification device.
The waste gas collecting device consists of a fan and an air pipe. The fan takes out the waste gas that paint spray booth, drying chamber etc. produced in the activity of spraying paint out, through the tuber pipe, sends into coarse-effect purifier, active carbon purifier, photocatalysis purifier in proper order. The three purification devices can be made independent according to the waste gas amount, the waste gas concentration and the transportation condition and are connected with each other by an air pipe; or can be made into a whole body which is internally connected with the air pipe. The purified clean air is directly discharged into the atmosphere by the air pipe.
The coarse purification device is used for performing coarse purification on waste gas by using a plurality of layers of filter felts to remove large-particle gas waste. The filter felt can be made of glass fiber materials with high strength, strong elasticity, fracture resistance and small resistance, and the fibers tend to be gradually dense in the flowing direction of waste gas. Because the waste gas particles are different in size and are in a gradually-dense structure, different particle sizes are blocked at different levels, and the adsorption capacity of the filter felt is increased. And when the filter felt works, the filter felt is rubbed with the pressurized air to generate static electricity, so that the adsorption of exhaust gas particles is further increased.
The activated carbon purification device is made of a plurality of layers of activated carbon fiber felts or activated carbon sponges. The activated carbon fiber felt is formed by fusing activated carbon powder into a fibrous non-woven fabric; the active carbon sponge is made of powdered active carbon adhered to polyurethane base material by high molecular adhesive material. Both have high adsorption performance. Can remove volatile organic compounds, paint mist, foul smell, benzene, phenols, alcohols, aldehydes and other pollutants.
The photocatalytic purification device adopts high-energy UV light beams and a TiO2 photocatalyst net. The high-energy UV light beam can irradiate the whole photocatalytic purification area; the TiO2 photocatalyst net is made of paper-based fiber net filled with one of polyurethane cotton, glass fiber cloth, honeycomb aluminum foil, stainless steel net and honeycomb ceramic material or any combination of the two. So as to increase the surface area of the carrier, prolong the retention time of the pollutants on the photocatalyst net and improve the purification effect.
Oxygen ions in the air are decomposed by the high-energy UV light beams to generate free oxygen, positive and negative electrons carried by the free oxygen are unbalanced, the free oxygen needs to be combined with oxygen molecules, ozone is generated, the ozone has extremely strong oxidation effect on organic matters, and pungent odor in waste gas is effectively removed.
And the TiO2 photocatalyst net can generate photoinduced electrons with stronger reducing capability and photoinduced holes with oxidizing capability when irradiated by UV light beams. The free radicals and harmful gases are subjected to oxidation reaction to generate CO2, H2O and some simple low molecules, so that the effect of decomposing the harmful gases is achieved.
According to the invention, the main pollutants such as volatile organic compounds, inorganic substances, hydrogen sulfide, ammonia gas and thiols can be efficiently treated without pretreating gas, harmful substances in the main pollutants are decomposed, harmless emission can be completely achieved, and secondary pollution is never generated; meanwhile, various pungent tastes can be purified, the deodorization capacity can reach more than 99.9 percent, and the working environment of a factory workshop is greatly improved. The device has the advantages of high working efficiency, low operation cost, no noise, no need of special management and daily maintenance, only need of periodic inspection, stable performance, long service life and the like.

Detailed Description
Steel structure spraying is always carried out in a workshop in a certain factory, so that stimulating paint smell is scattered everywhere in the whole workshop, serious pollution is caused, and toxic and harmful gas is diffused; workers in a workshop often feel headache, dizziness and nausea and cannot continue working; the medical expenses of enterprises are increased, and the labor cost is increased; workers are not willing to do related work for health, and personnel loss is serious. In order to solve the problems, an air purification device is introduced into a factory, a part which possibly generates waste gas is isolated, a fan and an air pipe are installed, the fan extracts the waste gas at the isolated part, the waste gas is conveyed to the air purification device through the air pipe, and after the waste gas is treated by the purification device, no peculiar smell is generated obviously. The purposes of improving the air in the workshop and ensuring the health of workers are achieved.
