Abstract

The invention relates to devices for liquid degassing, can be used in heat power engineering, metallurgical and chemical industry, in nuclear power engineering and allows increasing the degree of degassing. The efficiency of the liquid degassing process is increased by executing the acoustic emitter 5 as a part of a spherical surface located coaxially with the transition chamber 4 in the form of a Veituri tube and installed at the base of the RING 6 of a triangular cross section connected at the top with the transition chamber in its minimum plane section. 1 il.

Description

eleven

The invention relates to devices for the degassing of a liquid and can be used in heat and power engineering, metallurgical and chemical industry.

The purpose of the invention is to increase the degree of degassing.

The drawing shows a diagram of a device for degassing a liquid.

The device comprises a housing 1 in the form of two cylinders, tangential nozzles 2, exhaust pipes 3, a transition chamber 4 in the form of a Venturi tube, an acoustic emitter 5, a ring chamber 6.

The device works as follows.

The fluid, flowing tangentially through one of the nozzles 2, acquires a rotational motion, which leads to a decrease in the static pressure in the fluid. In the transition chamber, an increase in the rotational speed and axial velocity occurs, which leads to a further decrease in the static pressure in the fluid. After the passage of chamber 4, the liquid enters the second tangential nozzle 2. The excitation of acoustic oscillations in the radiator 5 leads to the formation of a cavitation region in the focal zone in the chamber 6. The gas in the liquid diffuses into the bubbles as they expand and is removed through the vapor pipes 3

The implementation of the venturi tube transition chamber reduces the pressure in the focal zone of the radiator, thereby intensifying the degassing process. Availability

the annular chamber provides a further decrease in pressure in the focal zone of the radiator and enhances the action of the acoustic radiator,

The implementation of an acoustic radiator in the form of a spherical segment increases the degree of concentration of acoustic energy, and, consequently, the amplitude of tensile stresses.

in the cavitation area. Increasing the amplitude of the tensile stresses leads to an increase in the maximum radius of the vapor-gas bubble, and hence the amount of gas

diffused from the liquid into the bubble.
