Abstract
A system for cleaning water in rivers or lakes or for separating oil and water. The system includes a sucking pipe; vapor-liquid mixing device connecting to the sucking pipe; a pressure pump disposed midway of the sucking pipe; a compressor connected to the connection between the pressure pump and the vapor-liquid mixing device; a pressure tank connected to the vapor-liquid mixing device; a feed pipe connected to the pressure tank; and a pressure valve, attached to the leading end of the feed pipe, which opens at a pressure exceeding a predetermined level. According to this system, the construction can be simplified, and the lifting action by the bubbles can be effected by keeping the pressure of the liquid at a predetermined level or more at all times. Thus, the system can be used anywhere under all circumstances.
Claims11
A bubbling system apparatus comprising:
- a sucking pipe;
- gas-liquid mixing means connecting to said sucking pipe;
- a pressure pump disposed midway of said sucking pipe;
- compressor means connected to the connection between said pressure pump and said gas-liquid mixing means for introducing a gas into said sucking pipe;
- a pressure tank connected to said gas-liquid mixing means;
- a feed pipe connected to said pressure tank;
- and a pressure valve, attached to the leading end of said feed pipe, said pressure valve including means for biasing said valve in a closed position until a predetermined pressure of about 7 kg/cm.sup.2 is exceeded whereafter the pressure opens the valve.
A cleaning system apparatus comprising:
- a pressure pump for sucking and feeding a stock liquid, the stock liquid being sucked from a portion to be treated by a sucking pipe, the sucked stock liquid being fed to gas-liquid mixing means;
- compressor means for feeding a compressed gas into the stock liquid to be fed to said gas-liquid mixing means by said pressure pump;
- said gas-liquid mixing means for mixing the treated stock liquid fed by said pressure pump and the compressed gas fed from said compressor means, to mix and dissolve the gas into the liquid;
- a pressure tank means for receiving the pressure liquid having said gas mixed and dissolved therein and for reserving the pressure liquid having said gas mixed and dissolved therein;
- a feed pipe means for feeding the pressure liquid of said pressure tank means to said treated portion;
- and a pressure valve attached to the leading end of said feed pipe means which includes means for biasing said valve in a closed position until a predetermined pressure of about 7 kg/cm.sup.2 is exceeded whereafter the pressure opens the valve.
An oil-water separating system apparatus comprising:
- a pressure pump for sucking and feeding a stock liquid, the stock liquid being sucked from a portion to be treated by a sucking pipe, the sucked stock liquid being fed to vapor-liquid mixing means;
- compressor means for feeding a compressed gas into the stock liquid to be fed to said vapor-liquid mixing means by said pressure pump;
- said vapor-liquid mixing means for mixing the treated stock liquid fed by said pressure pump and the compressed gas fed from said compressor means, to mix and dissolve the gas into the liquid;
- a pressure tank means for receiving the pressure liquid having said gas mixed and dissolved therein and for reserving the pressure liquid having said gas mixed and dissolved therein;
- a feed pipe means for feeding the pressure liquid of said pressure tank means to said treated portion;
- and a pressure valve attached to the leading end of said feed pipe means which includes means for biasing said valve in a closed position until a predetermined pressure of about 7 kg/cm.sup.2 is exceeded whereafter the pressure opens the valve.
A bubbling system apparatus consisting essentially of:
- a sucking pipe;
- gas-liquid mixing means connecting to said sucking pipe;
- a pressure pump disposed midway of said sucking pipe;
- compressor means connected between said pressure pump and said gas-liquid mixing means for introducing a gas into said sucking pipe;
- a pressure tank connected to said gas-liquid mixing means;
- a feed pipe connected to said pressure tank;
- and a pressure valve, attached to the leading end of said feed pipe, which includes means for biasing said valve in a closed position until a predetermined pressure of about 7 kg/cm.sup.2 is exceeded whereafter the pressure opens the valve.
