Description
Technical Field
The utility model relates to the technical field of adsorbers, in particular to a rapid cooling adsorber.
Background
An adsorber refers to a device that purifies harmful gases using the adsorption capacity of solids for the gases. In the gas purification industry, the micropores of an adsorption material (carbon material) are often utilized to intercept and enrich the VOCs component (solvent) in the gas (generally referred to as adsorption process), and then the solvent is collected by heating (generally referred to as desorption process). The heat source usually used is saturated steam, the solvent adsorbed in the desorption process is enriched along with the desorption direction of the steam, most of the solvent is desorbed, and only a small amount of solvent remains on the carbon layer at the outlet end of the desorption of the steam. And in the drying and cooling process, heat on the carbon layer is taken away by air/nitrogen, and the carbon layer is rapidly cooled so as to be adsorbed next time. If the dry gas is directly exhausted, a small amount of residual solvent is exhausted together, so that the exhaust gas exceeds the standard; if the dry gas circulates, the water vapor in the absorber is condensed immediately in the rapid cooling process, the circulating gas becomes saturated gas of water, the dewatering efficiency is reduced, more water remains on the carbon layer, and the adsorption value of the next adsorption is affected. The conventional treatment method is to establish a hot air circulation, remove most of water vapor first, and then continue drying and cooling.
In the solvent collection process on the adsorber adsorption material, the desorption is generally carried out through vapor first, residual moisture and solvent are easy to remain on the adsorption material after the desorption, and drying is needed subsequently, but the existing adsorber has low drying efficiency on the adsorption material, generally removes the moisture through thermal circulation, cannot cool and dry the adsorption material rapidly, and reduces the drying efficiency on the adsorption material.
