Description
Technical Field

Background
Volatile Organic Compounds (VOCs) are PM in the atmosphere2.5And O3Some of the important precursors (such as benzene and formaldehyde) can also directly harm human health, so that the control of volatile organic compounds is always the key point of atmospheric environment protection. In recent years, PM (particulate matter) is increased along with the increase of air pollution control intensity in China2.5The concentration decreases year by year, and O3The pollution is more prominent. A large number of researches find that the ozone pollution formation in most urban areas of China is in VOCs sensitive areas, so that the effective control of VOCs becomes important content of regional ozone prevention and control. Among them, industrial source emission is one of the important sources of VOCs in the atmosphere, and has become the focus of attention for reducing the emission of VOCs in the atmosphere.

The adsorbent is usually selected from activated carbon and molecular sieves, wherein the activated carbon has larger specific surface area and more micropores, can simultaneously adsorb a plurality of volatile organic compounds, is low in price and wide in application, but is extremely easy to cause spontaneous combustion or explosion by high-temperature desorption; the molecular sieve is used as an adsorbent for catalytic combustion and widely applied to industrial waste gas treatment due to firm structure and good thermal stability, but has selectivity on volatile organic compounds, and cannot ensure complete absorption of multi-species VOCs for complex pollution sources. In addition, the adsorbent for adsorbing VOCs belongs to hazardous waste, and if harmless disposal cannot be achieved in a factory, huge capital is required to be entrusted to a professional company for treatment, so that a large economic burden is brought to enterprises. And if the tail gas treated by the adsorption method does not have on-line monitoring equipment, whether the adsorbent works normally cannot be evaluated, and the excessive emission of volatile organic compounds is easily caused.
Based on the existing research basis, the problems existing in the existing VOCs treatment process are fully considered, and the utility model provides a method and a device for efficiently collecting, treating and purifying volatile organic compounds by combining temperature and pressure. The method comprises the steps of firstly utilizing an adsorbent to complete efficient adsorption of industrial source VOCs, then carrying out efficient desorption and activation on the adsorbent through vacuum gradient temperature rise control, finally collecting desorbed VOCs into a storage tank, and finally carrying out comprehensive utilization or harmless treatment on high-concentration VOCs in the tank, thereby finally realizing efficient green treatment and recycling of the VOCs.
