METHOD AND UNIT FOR CLEANING OF INDUSTRIALLY PRODUCED STRUCTURAL ELEMENTS Russian patent published in 2015 - IPC B08B15/02 

FIELD: process engineering.

SUBSTANCE: invention relates to cleaning of industrially produced structural elements. Unit (30) comprises cleaning space (2) and suction device (7) to suck outcoming air (V_ab) as detergent evaporations from cleaning space (2). Claimed unit comprises regenerator (5) accommodating refrigerator (6) with cooling register (8) for outcoming air (V_ab) to be cooled therein and dried and heating register (9). Sucked off outcoming air (V_ab) is forced to regenerator (5) via refrigerator (6) heating register (9) and heated to, in fact, outcoming air temperature. Then, heated and dried outcoming air (V_ab) is fed via air-in pipe (17) to cleaning space (2) as a preheated dry in-air (V_zu). In-air pipe (17) extends into cleaning space (2) in the area of sluice door (16) to produce air curtain in said space (2) behind said door (16) by fed in-air (V_zu) to prevent the escape of detergent evaporations at opening of said sluice door (16).

EFFECT: saving of detergent and heat.
