Technical Field
The invention relates to the technical field of industrial harmful waste gas treatment, in particular to an industrial harmful waste gas treatment and recovery device based on atmospheric pollution control.
Background
The industrial waste gas is a harmful state generated by burning coal, steelmaking and thermal power generation in industrial production, and can be divided into granular waste gas and gaseous waste gas by morphological analysis, wherein the granular waste gas is mainly polluting smoke dust generated in the production process and mainly comes from cement plants, heavy industrial material production plants, heavy metal manufacturing plants, chemical plants and the like. In production, the raw materials required by such enterprises need to be purified, and because of more impurities, the purified combustible materials cannot be completely combusted and decomposed, so that the waste gas is formed in a smoke form and is discharged into the atmosphere to cause air pollution. Among them, the most harmful are gaseous waste gases which are the most various in industrial waste gases. At present, the gas waste gas mainly comprises nitrogen-containing organic waste gas, sulfur-containing waste gas and hydrocarbon organic waste gas; the nitrogen-containing waste gas can damage air components, change the gas composition proportion, particularly the combustion of petroleum products, the combustion amount of the petroleum products is huge in industrial production, and the content of nitrides in the petroleum products is large, so that the waste gas can contain a large amount of nitrogen oxides, and if the waste gas is discharged into the air, the content of the nitrogen oxides in the air can be increased, and the influence on the atmospheric circulation is caused; the use of urea sulfur-containing exhaust gas can cause direct harm to the living environment of people, because it can form acidic substances in combination with water in the air, causing acid rain. Acid rain can cause damage to plants, buildings and human health, and particularly can affect the respiratory tract of people. In addition, the method can also affect soil and water sources and cause secondary pollution; hydrocarbon organic exhaust gas is an organic compound, mainly composed of carbon atoms and hydrogen atoms. The diffusion of such waste gases into the atmosphere causes a series of problems and effects on the destruction of the ozone layer. For example, ozone depletion aggravates ultraviolet radiation, which can cause damage to human skin and cause various health problems. In addition, the change of the ultraviolet irradiation degree can also cause influence on the ecological system and the climate; the industrial waste gas treatment principle includes various principles such as an activated carbon adsorption method, a catalytic combustion method, a catalytic oxidation method, an acid-base neutralization method, a plasma method and the like.
When industrial waste gas is treated, the existing industrial harmful waste gas treatment and recovery equipment can only treat single type of waste gas and cannot treat and recycle different substances contained in the waste gas in a targeted manner.
