The invention provides a compact type VOCs (Volatile Organic Chemicals) adsorption and desorption-purification integration device resistance to wide load impact, and a method. The device comprises anadsorption-desorption unit provided with a first air inlet, a second air inlet, a first air outlet and a second air outlet; an adsorption fan arranged on the first air inlet; a first exhaust gas on-line monitoring unit arranged on the first air outlet; a desorption fan arranged on the second air outlet. The method comprises the steps of opening an adsorption channel, and closing a desorption channel; opening the adsorption fan, purifying VOCs, and monitoring the exhaust concentration in real time; judging whether the concentration of a gas exhausted from the second air outlet is larger than afirst preset value or not; if the concentration is larger than the first preset value, closing the adsorption channel, and opening the desorption channel; closing the adsorption fan, opening the desorption fan, and desorbing a fixed bed molecular sieve. The device provided by the invention can be used for effectively adsorbing the VOCs components, is good in airtightness and stable to operate, iscapable of adjusting an exhaust gas treatment load according to the actual working condition so as to reduce cost, has the advantages of compact structure and load impact resistance, and is applicableto enterprise production.
Description
technical field [0001] The invention relates to the field of volatile organic compound treatment, in particular to a compact VOCs absorption-desorption-purification integrated device and method capable of withstanding wide load shocks. Background technique [0002] Volatile organic compounds (volatile organic compounds, VOCs) have a wide variety, complex composition, and different properties. In many cases, it is difficult to meet the emission requirements by using a purification technology, and it is uneconomical. Therefore, in the process of organic waste gas treatment, a combination of two or more purification technologies is often used. On the one hand, it can meet the exhaust gas emission requirements, and on the other hand, it can also reduce the operating cost of the purification equipment. Zeolite rotor adsorption technology is often combined with catalytic combustion or high-temperature incineration technology to form zeolite rotor adsorption + catalytic combustion...
