METHOD AND EQUIPMENT FOR CONCENTRATION

PURPOSE:To provide a concentrating method and equipment attaining the rationalization of exhaust gas treatment where the desorption of detrimental/ malodorous gas components and the adhesion of adhesive dust are executed during pneumatic conveying using a powder adsorbent and simultaneously desorption is easily and surely executed with small quantity of regeneration gas to make exhaust gas treatment with high concentration, good efficiency and low running cost using compact structure. CONSTITUTION:A pneumatic conveying means 8 where gas to be treated containing adhesive powder and detrimental/malodorous gas components is mixed with a powder adsorbent to pneumatically convey the mixture, a separation means 11 for separating the powder adsorbent from the gas to be treated containing the adsorbent from the pneumatic conveying means 8 and regenerators 12, 36 where the powder adsorbent separated by the separation means 11 is mixed with a hot blast to desorb it by heat regeneration and the gravitationally falling adsorbent countercurrently comes into contact with regeneration gas blown from below to desorb it by purge regeneration are included. Thereby the concentrated detrimental/malodorous gas components are obtained from the regenerator 12, 36.
