Abstract
The invention relates to a diffusor for adding of gases into water, said diffusor comprising a perforated tube (1) and at least one supply tube (2), said the at least one supply tube (2) is at one end coupled to a source for supplying gas and at the other end in fluid communication with the perforated tube (1), the gas is supplied to the perforated tube (1) through at least one inner supply tube (4; 5; 15) extending from the supply tube (2) to the perforated tube (1). The invention is distinctive in that at the least one inner supply tube (4; 5; 15) is a non-perforating tube and has at least one outlet (4a, 5a, 15a) situated at a free end of the at least one inner supply tube (4, 5, 15), said gas is adapted to be distributed into the perforated tube (1) through the at least one outlet (4a, 5a, 15a).
Claims15
A diffusor for adding of gases into water, the diffusor comprising a perforated tube and at least one supply tube, the at least one supply tube is at one end coupled to a source for supplying gas and at the other end in fluid communication with the perforated tube, the gas is supplied to the perforated tube through at least one inner supply tube extending from the supply tube to the perforated tube, wherein at the least one inner supply tube is a non-perforating tube and has at least one outlet situated at a free end of the at least one inner supply tube, the gas is adapted to be distributed into the perforated tube through the at least one outlet.
A method for evacuating water from or clean or disinfect a diffusor, the diffusor comprising a perforated tube and at least one supply tube, the at least one supply tube is in fluid communication with the perforated tube through at least one inner supply tube extending from the supply tube into the perforated tube (1), the method comprising:
- arranging a pressure relief valve at a second end of the perforated tube;
- supplying a pressure gas or a disinfectant through the supply tube into at least one inner supply outlet situated on the free end of the at least one inner supply tube;
- and
- displacing the water or contaminant out of the diffusor through the pressure relief valve, until a substantial portion of the water or contaminant is evacuated out of the diffusor.
