Abstract

PURPOSE: To treat sludge inexpensively and easily in a short time without stopping the operation of a storage tank, by jetting a stored liquid by a pump set on a floating ceiling so that the sludge deposited on the bottom of the storage tank is granulated and dissolved.
CONSTITUTION: The pump 3 set on the floating ceiling 2 of the storage tank 1 is connected with the flexible hoses 4 at its suction side and the delivery side respectively. The flexible hose 4 at the suction side of the pump 3 is communicated with the suction nozzle 5, and the flexible hose 4 at the delivery side with the jetting nozzle 7. When the pump 3 is operated, a stored liquid is sent from the suction nozzle 5 through the flexible hose 4 to the jetting nozzle 7 and as a jetting flow hit to the slude, so that the sludge is granulated, dispersed into the storage tank, and partially dissolved.
EFFECT: Sealing by an inert gas is unnecessary, and drainage treatment is not required because of no use of water, steam, etc.
