METHOD OF CLEANING INNER SURFACES OF WATER AND SEWAGE PIPELINES AND VESSELS FROM MECHANICAL AND BIO-CHEMICAL DEPOSITS

摘要

FIELD: cleaning inner surfaces of vessels in various fields of economy. SUBSTANCE: method is based on following: liquid which fills tube or vessel is subjected to successive pneumatic-pulse oscillation operations with carrier frequency within 1 to 100 Hz together with varying frequency of oscillating actions within each successive operation in combination with heating by super-high frequency current and washing out of deposits which cover inner surfaces of tubes or vessels by streams of liquid. This leads to changing physical properties of deposits, softening them and subsequent removing especially from bottom and side surfaces. EFFECT: high efficiency.
