Description
Technical Field
The invention belongs to the field of environmental protection, and particularly relates to a device for collecting and purifying welding waste gas, preventing air pollution and harming the health of workers.
Background
The pollution in the industrial production process is mainly caused by the unorganized emission in the production process, waste gas cannot be effectively collected and treated, and the waste gas is directly emitted into the atmosphere to pollute the surrounding environment, so that the pollution is one of the main reasons for forming photochemical smog in the surrounding areas of cities. In addition, the volatilized organic waste gas is emitted in the air, and can cause nausea, vomiting, allergy, mental confusion, chronic or acute poisoning and harm the physical health of workers after entering the human body through the respiratory tract except for generating stimulation to eyes and nasal mucosa of the workers. The existing waste gas purification devices have two types, one is large-scale space purification, and the air in the whole welding workshop is completely purified, so that the defects of high cost and high operation cost are caused. The other type is a small fixed waste gas purifying device, and has the defects that only local air can be purified, and the purifying effect is greatly reduced when the welding point is slightly far away.
Disclosure of Invention
In order to solve the problems that a large amount of toxic and harmful gas is generated in the welding process and the health of welding personnel is harmed, the invention provides a movable waste gas purification device for industrial production, so that the effects of saving cost and purifying waste gas are achieved; the exhaust gas collector can move along with the movement of the welding point, so that the collection of the exhaust gas can be enhanced from the source, the discharge of toxic gas is reduced, and the pollution to the environment is reduced.
The technical scheme of the invention is as follows: the industrial waste gas purifier consists of purifier, wind collector and support. The supporting device is arranged below the wind collecting device, plays a role in bearing stress and supports the wind collecting device. The wind collecting device is connected with the purifying device.
The air collecting device consists of a fume collecting hood, an air pipe and a fan, wherein one end of the air pipe is connected with the fume collecting hood, and the other end of the air pipe is connected with the fan.
The fume collecting hood is in the shape of a horn with a quadrangular frustum inner cavity with a small upper opening and a large lower opening.
The centrifugal fan is selected as the fan, and the fan has the characteristics of low noise, high efficiency, small volume, large air quantity, easy installation and the like. The air inlet of the fan is circular and is provided with a flange hem and a fixing screw hole, so that the fan can be conveniently butted with the fourth bent pipe; the fan air outlet is rectangular, fixed screw holes are uniformly distributed on the fan air outlet, and the outlet direction of the fan air outlet faces downwards and is connected with a fan outlet section pipeline.
The waste gas purifying device is composed of a coarse purifying area, an active carbon purifying area and a photocatalysis purifying area.
The coarse purification area is used for performing coarse purification on the waste gas by using a plurality of layers of filter felts to remove large-particle gas waste. The filter felt is made of glass fiber materials, and the fibers tend to be gradually dense in the flowing direction of the 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 area 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 polyurethane base material and powdered active carbon adhered with high molecular adhesive material. Both have high adsorption performance. Removing pollutants such as organic compound odor.
The photocatalytic purification area adopts high-energy UV light beams and TiO2A photocatalyst net. The high-energy UV light beam can irradiate the whole photocatalytic purification area; TiO 22The photocatalyst carrier can adopt a paper-based fiber meshThe surface area of the carrier is increased by materials such as polyurethane cotton, glass fiber cloth, honeycomb aluminum foil, stainless steel mesh, honeycomb ceramic and the like, so that the retention time of pollutants on the photocatalyst mesh can be prolonged, and the purification effect is improved.
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 TiO 22The 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 oxidized to generate CO2、H2O and some simple low molecules, thereby achieving the function of decomposing harmful gases.
