FIELD: process engineering.SUBSTANCE: invention relates to cleaning inner surface of tubular structure, e.g. tubes, chutes, etc of solid and liquid dirt and may be used in whatever industry. Proposed method comprises forming three cavities inside structure to be cleaned. Note here that first and second cavities are formed by deflected sections. Third cavity is formed by first length an structure walls. Gas is fed into first cavity while fluid is fed into second cavity. Note here that gas in first cavity is periodically fed into second cavity. Mix formed in second cavity is fed into third cavity. Note here that second length reciprocates in said third cavity. Proposed device comprises chambers communicated with fluid and gas feed systems and tube lengths arrange there inside. One end of pipe lengths is deflected and secured over the edges of appropriate chamber while opposite end is connected with appropriate pull mechanism. Said tube lengths are communicated with said fluid and gas systems to periodically shut them off.EFFECT: higher efficiency of cleaning.5 cl, 2 dwg |
