Description

Reverse cross-flow hypergravity device with choke wall

The present invention relates to a supergravity device, in particular to a reverse cross-flow supergravity device with a gas-blocking ring wall.

Existing hypergravity devices can be used to intercept and remove aerosols or soluble gaseous pollutants in the gas. However, if a counter-flow supergravity device is used, the contact time between the gas and the liquid is short, and the effect of removing pollutants is relatively limited; if a cross-flow supergravity device is used, holes are usually dug in the rotating bed substrate connected to the rotating shaft. Alternatively, the rotating bed base plate is replaced with support ribs for the gas to pass through. Therefore, a thicker rotating bed base plate or reinforced support ribs can be used to maintain the structure of the rotating bed, thereby increasing the manufacturing constraints of the supergravity device. In addition, when the concentration of suspended particles is high, if a cross-flow supergravity device is used, the openings on the outer peripheral surface of the rotating bed are generally small, so that the intercepted suspended particles are easily blocked or accumulated in the rotating bed.

Therefore, the purpose of the present invention is to provide a reverse cross-flow supergravity device with a gas choke ring wall, which can avoid the above-mentioned problems that are prone to occur in the prior art.

Therefore, the reverse cross-flow supergravity device with choke wall of the present invention includes a housing, a bearing seat, a rotating shaft, a rotating bed unit and a liquid conduit. The casing includes a bottom wall, a top wall and a surrounding wall. The top wall is opposite to the bottom wall and has a gas outlet for leading gas out of the casing. The surrounding wall is connected to the bottom wall and the top wall and has an air inlet for introducing gas into the casing. The bearing seat passes through the bottom wall. The rotating shaft is rotatably passed through the bearing seat. The rotating bed unit is arranged in the housing. The rotating bed unit includes a base plate, an annular opening top plate opposite to the base plate in the axial direction of the rotating shaft, a filling layer in the shape of a hollow cylinder and allowing fluid to penetrate, and a gas choke ring wall. The base plate is connected to the rotating shaft and is spaced apart from the housing. The perforated top plate allows fluid to pass through and is connected to the housing by a first dynamic seal. The filling layer extends from the base plate in the direction opposite to the bearing seat to the perforated top plate in the axial direction of the rotating shaft, and has an annular bottom surface in contact with the base plate, and a bottom surface in contact with the perforated top plate and in the shape of an annular shape. An annular top surface, an outer peripheral surface connected to the outer peripheral edge of the bottom surface and the outer peripheral edge of the top surface, and an inner peripheral surface connected to the inner peripheral edge of the bottom surface and the inner peripheral edge of the top surface. The inner peripheral surface defines a liquid spraying space inside. The baffle ring wall surrounds a portion of the outer peripheral surface adjacent to the outer peripheral edge of the top surface of the filling layer, and is spaced from the substrate to block the gas introduced into the housing from the air inlet from directly penetrating the outer peripheral surface adjacent to the filling layer. Part of the outer peripheral surface of the outer peripheral edge of the top surface.
