<p>PURPOSE: A chemical introducing apparatus based on spiral hydraulic pressure formation and differential pressures is provided to generate differential pressures by using a part of introduced water in a water tank without a pressure adjusting valve and a branch pipe. CONSTITUTION: Water is introduced through the vertical introducing pipe of a water introducing pipe(200) in a water tank(121). Differential pressures are generated based on the water without a pressure adjusting valve or a branch pipe. A spiral hydraulic pressure forming pipe(700) is formed at an elbow pipe which is the discharging hole of the water introducing pipe. An introduced water combining pipe is formed at the body of the spiral hydraulic pressure forming pipe. A hydraulic pressure forming overflow pipe is formed at one upper part of the body. The lower side of the body is conically shaped. A venturi is formed at the center of the body. A chemical transferring pipe(500) is formed at the venturi. Hydraulic pressures are formed in case of introducing water. Storing sucking force is generated at the venturi by spirally rotating water flow. Liquefied chlorine from a chemical storing tank(400) is introduced with water.</p> |
