Abstract
The invention relates to a filling device for dense loading of a chemical reactor with particulate catalyst material. In particular, it relates to a device for even distribution of the catalyst material by centrifugal force. Furthermore, the invention relates to novel distribution devices, and a method for dense loading of a chemical reactor using a filling device described herein.
Claims29
A filling device for dense loading of a chemical reactor with particulate catalyst material, comprising:
- a feed hopper for particulate catalyst material, having an upper end provided with an upper inlet opening and a lower end provided with a lower outlet opening;
- a distribution device that is arranged (i) below the feed hopper for distributing the particulate catalyst material in the chemical reactor by centrifugal force, and (ii) rotatably around a vertical rotation axis, wherein the distribution device comprises at least a first annular distribution element that has an upper, annular, substantially horizontal inlet opening with a clear width, a substantially vertical outlet opening directed radially outwards with respect to the rotation axis with a clear height, and a deflection element arranged between the inlet opening and the outlet opening, wherein the deflection element deflects a substantially vertical particle flow coming from the feed hopper into a substantially horizontal particle flow;
- a drive bearing arranged radially symmetrically to the rotation axis, which has a fixed bearing ring directly or indirectly connected to the feed hopper and a rotating bearing ring connected to the distribution device;
- and
- a drive device that has a drive motor arranged laterally offset from the vertical rotation axis outside the feed hopper, and a belt drive, wherein the drive motor drives the rotating bearing ring of the drive bearing via the belt drive;
- wherein:
- the clear height of the outlet opening is greater than the clear width of the inlet opening, and
- the deflection element has a guide surface which has a substantially vertical tangent at the inlet opening and a substantially horizontal tangent at the outlet opening, where the radius of curvature of the guide surface increases continuously from the inlet opening to the outlet opening.
A filling device for dense loading of a chemical reactor with particulate catalyst material, comprising:
- a feed hopper for particulate catalyst material, having an upper end provided with an upper inlet opening and a lower end provided with a lower outlet opening;
- a distribution device that is arranged (i) below the feed hopper for distributing the particulate catalyst material in the chemical reactor by centrifugal force, and (ii) rotatably around a vertical rotation axis, wherein the distribution device comprises at least a first annular distribution element that has an upper, annular, substantially horizontal inlet opening with a clear width, a substantially vertical outlet opening directed radially outwards with respect to the rotation axis with a clear height, and a deflection element arranged between the inlet opening and the outlet opening, wherein the deflection element deflects a substantially vertical particle flow coming from the feed hopper into a substantially horizontal particle flow;
- a drive bearing arranged radially symmetrically to the rotation axis, which has a fixed bearing ring directly or indirectly connected to the feed hopper and a rotating bearing ring connected to the distribution device;
- and
- a drive device that has a drive motor arranged laterally offset from the vertical rotation axis outside the feed hopper, and a belt drive, wherein the drive motor drives the rotating bearing ring of the drive bearing via the belt drive;
- wherein:
- the drive bearing is arranged inside a peripheral bearing housing;
- the peripheral bearing housing can be supplied with a purge gas flow;
- the drive motor and the drive bearing are fastened to a radial carrier plate arranged between the feed hopper and the distribution device;
- the radial carrier plate forms an upper side of the peripheral bearing housing;
- the fixed bearing ring of the drive bearing is connected to the radial carrier plate;
- and
- passage openings for the purge gas are provided between the radial carrier plate and the fixed bearing ring.
A filling device for dense loading of a chemical reactor with particulate catalyst material, comprising:
- a feed hopper for particulate catalyst material, having an upper end provided with an upper inlet opening and a lower end provided with a lower outlet opening;
- a distribution device that is arranged (i) below the feed hopper for distributing the particulate catalyst material in the chemical reactor by centrifugal force, and (ii) rotatably around a vertical rotation axis, wherein the distribution device comprises at least a first annular distribution element that has an upper, annular, substantially horizontal inlet opening with a clear width, a substantially vertical outlet opening directed radially outwards with respect to the rotation axis with a clear height, and a deflection element arranged between the inlet opening and the outlet opening, wherein the deflection element deflects a substantially vertical particle flow coming from the feed hopper into a substantially horizontal particle flow;
- a drive bearing arranged radially symmetrically to the rotation axis, which has a fixed bearing ring directly or indirectly connected to the feed hopper and a rotating bearing ring connected to the distribution device;
- and
- a drive device that has a drive motor arranged laterally offset from the vertical rotation axis outside the feed hopper, and a belt drive, wherein the drive motor drives the rotating bearing ring of the drive bearing via the belt drive;
- wherein:
- the lower end of the feed hopper has at least one annular insert, which feeds the particle flow at least to the first annular distribution element;
- and
- the at least one annular insert consists of at least one concentric, annular tube arranged radially symmetrically around the rotation axis, which in each case supplies a partial flow of the particle flow to an allocated distribution element.
