Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment, in particular to a plant liquid for absorbing organic waste gas, and a machine for treating organic waste gas with the plant liquid. Background technique [0002] During the rapid development of our country, the increasingly serious environmental protection issues have attracted the attention of all parties in the society, which has spawned a lot of equipment for VOCs treatment, such as activated carbon adsorption, plasma, ultraviolet light and other equipment commonly used. However, these purification equipment for VOCs have certain limitations, such as activated carbon adsorption equipment: low adsorption capacity, easy to reach saturation, short life, high regeneration cost, and eventually form hazardous waste; if the equipment stops operating, due to the loss of negative pressure, it has already The adsorbed activated carbon will desorb and release VOCs; its operation is also af...

Problems solved by technology

However, these purification equipment for VOCs have certain limitations, such as activated carbon adsorption equipment: low adsorption capacity, easy to reach saturation, short life, high regeneration cost, and eventually form hazardous waste; if the equipment stops operating, due to the loss of negative pressure, it has already The adsorbed activated carbon will desorb and release VOCs; its operation is also affected by the humidity, dust and temperature at work. The greater the humidity, the more dust, the worse the adsorption effect; Good for adsorption

The low-temperature plasma technology will also reduce the treatment efficiency due to the influence of water vapor and dust in the exhaust gas.

In addition, if low-energy plasma is used, the so-called plasma technology mostly uses the oil removal principle of range hood, which is basically not suitable for the treatment of VOCs containing benzene rings. If high-power plasma technology is used, there are also disadvantages, and the equipment is expensive, such as If the plasma is excited to generate an arc, it will inevitably produce secondary pollutants such as ozone, nitrogen oxides, and intermediate by-products of partial degradation of organic waste gas. What is more serious is that most of the organic waste gas is flammable and explosive compounds. , The design of the organic waste gas treatment project is slightly flawed, and the electric arc during plasma work can easily cause explosion accidents. The explosion in Tianjin has informed everyone of its potential safety hazards, and the time for this technology to be banned is running out

The application of ultraviolet photolysis technology will be affected by dust, so that the radiation energy will be continuously weakened, and ultraviolet rays with a wavelength of 185nm will generate a large amount of ozone, causing secondary pollution, and the current treatment methods basically have no instantaneous response effect (taken as a domestic one) A well-known ultraviolet lamp supplier introduced that if the organic waste gas in the photocatalytic area does not have enough time to undergo hydroxyl radical reaction, the degradation rate of organic waste gas will be less than 10%). In addition, if the titanium dioxide material currently used is not anatase type Titanium dioxide photocatalyst, basically no catalytic photolysis effect

[0003] If each type of treatment equipment and its combination methods are used, if there is no quantitative analysis of the treatment, and no targeted solutions are developed, the organic waste gas pollution cannot be effectively treated.

The waste gas from different emission sources is also very different. A single technology for organic waste gas treatment has been difficult to make the discharge of organic waste gas meet the increasingly stringent environmental protection requirements. Therefore, in order to realize the new situation of environmental protection, it is necessary to seek a combined process that meets environmental protection requirements and is more cost-effective. , to promote the innovation and development of organic waste gas treatment technology
