Abstract

The invention relates to the technical field of marine defoaming, in particular to a water wheel centrifugal defoaming device. The water wheel centrifugal defoaming device is provided with a shell, anair outlet and a liquid outlet are formed in the upper side and the lower side of the shell respectively, and the water wheel centrifugal defoaming device is characterized in that a defoaming assembly is arranged in the shell and comprises a volute flow guide cover, a water wheel rotor, a bubble capturing screen, a bubble filtering screen and a bubble collecting screen; the bubble capturing screen comprises a screen rod and an arc-shaped screen plate, the bubble collecting screen comprises a conical screen and an annular screen, liquid mixed with gas is defoamed three times through the voluteflow guide cover, the bubble capturing screen and the bubble filtering screen, and the water wheel centrifugal defoaming device has the advantages of being simple in structure, convenient to use, capable of saving energy, good in defoaming effect and the like.

Description

technical field [0001] The invention relates to the technical field of defoaming for ships, in particular to a water wheel centrifugal defoaming device with simple structure, convenient use, energy saving and good defoaming effect. Background technique [0002] As we all know, marine natural gas is heated by water glycol, and the water glycol solution is easy to foam. The solution containing bubbles has poor thermal conductivity. The bubbles in the high-speed fluid burst, which will cause cavitation of pumps and pipeline accessories. In severe cases will lead to system paralysis. Therefore, complex water glycol systems need to be equipped with defoaming devices. Defoaming devices are widely used in chemical industry, sewage treatment, food processing and other fields. There are many defoaming methods commonly used, which can be divided into physical defoaming method, mechanical defoaming method, chemical defoaming method and natural defoaming method according to the princi...
