Apparatus for cleaning a line

摘要

For the purpose of cleaning a line (2) which carries, in particular, a pasty fuel to a reactor (1), use is made of a scraper (10) which is sent, with the aid of a limited quantity of water, through that section of the line (2) which is situated between the entry of the latter into the reactor (1) and a three-way valve (4) arranged near to the inlet. The quantity of water is kept ready in a container (11) which is connected to a compressed-air connection (15) and a rinsing line (6). The rinsing line (6) opens into the line (2) downstream of the three-way valve (4) (drawing).
