Abstract

The invention discloses an organic waste gas adsorbing recovery device and a process. The device comprises at least two macromolecule resin adsorbing towers, a heat pump, a vacuum pump, a condenser, a liquid storing tank and the like, wherein the macromolecule resin adsorbing towers are internally provided with waste gas inlet regions, purifying regions for adsorbing and purifying gas and a purifying gas discharging region; the purifying regions are provided with adsorbing layers which are horizontally paved, the adsorbing layers are composed of multi-hole supporting plates fixed on the adsorbing towers, heat exchanging coils paved above the multi-hole supporting plates and macromolecule resin layers which are fully paved on the cross sections of the adsorbing towers above the heat exchanging coils successively in a overlaying manner, and the heat exchanging coils are provided with inlets and outlets communicated with the heat pump arranged outside the adsorbing towers. The organic waste gas adsorbing recovery device and the process provided by the invention have the advantages that a non-flammable macromolecule resin is adopted as an adsorbing material, the removing rate of middle-high concentration organic waste gas is more than 98%, the organic waste gas recovery rate is more than 95%, the resin is fully regenerated, and the organic waste gas can reach the discharge standard.

Description

(1) Technical field [0001] The invention relates to the technical field of air pollution control, in particular to an organic waste gas adsorption recovery device and process, which uses polymer resin as an adsorbent, and is especially suitable for medium-high concentration organic waste gas (VOCS) adsorption-desorption recovery. (2) Background technology [0002] Medium and high concentration organic waste gas is produced in the reaction system, vacuum drying system and storage system of petrochemical and pharmaceutical industries. The amount of organic waste gas is large, the purity and concentration are high, and if it is not treated in time, it will cause large-scale pollution accidents. The adsorption-desorption recovery process is an economical and efficient treatment technology for medium and high concentration organic waste gas. This process uses an adsorbent to absorb medium and high-concentration organic waste gas, and then uses regeneration technology to desorb or...
