Description
Technical Field
[0001] The utility model relates to the technical field of purification and recovery devices, in particular to an organic tail gas purification and recovery device. Background Art
[0002] Organic tail gas, also known as organic waste gas, refers to gas containing pollutants such as hydrocarbons and nitrogen oxides. Organic waste gas may contain a variety of different chemical substances, such as benzene, aldehydes, esters, etc. Compared with some industrial waste gases, the concentration of organic waste gas is often lower, but even so, its toxicity and harmfulness cannot be ignored. Many components in organic waste gas are harmful to human health. Long-term exposure may cause various health problems. Some organic waste gases may cause fires or explosions under certain conditions, increasing safety risks. Organic waste gas is difficult to decompose on its own in the natural environment, causing long-term pollution to the environment. Organic waste gas is discharged into the atmosphere, which will It has a serious impact on air quality, and thus poses a threat to the ecosystem and human health. Organic waste gas mainly comes from industrial production, transportation, home decoration and other fields. For example, in the chemical industry, the emission of organic waste gas is large and the composition is complex; automobile exhaust contains a large amount of carbon monoxide, nitrogen oxides and other harmful substances; home decoration process will produce formaldehyde, benzene and other harmful gases. Organic exhaust gas purification and recovery devices are widely used in printing, furniture, petrochemical, coal chemical, leather, textile printing and dyeing, rubber, plastics, shoemaking, pharmaceuticals, electronics, chemical fiber and other industries to treat medium and low air volume and medium and high concentration of organic exhaust gas.
[0003] Today's organic tail gas purification and recovery devices can basically meet people's needs, but there are still some problems. The specific problems are as follows:
[0004] 1. The problem that the organic tail gas purification and recovery device is difficult to recycle repeatedly. After the tail gas is purified and recovered, the adsorption material will gradually age with the increase of usage time, causing the adsorption capacity to reach saturation and becoming difficult to use again. The adsorption material needs to be replaced regularly, which affects work efficiency and increases the cost of purification and recovery.
[0005] 2. The problem that the organic tail gas purification and recovery device is difficult to collect the separated substances. The separated substances after the organic tail gas purification and recovery are mostly organic matter, which can be reused, but are adsorbed in the adsorption material and cannot be removed, resulting in a waste of resources.
