In a process for recycling fine-particle solids (4) discharged from a reactor vessel (1) at a discharging position of the reactor vessel (1) by means of a gas, at a recycling position (16) of the reactor vessel (1), the solids (4) are separated in a solids separator (3) and subsequently collected in a collecting vessel (8) and from the same are recycled into the reactor vessel (1) by means of a conveying gas. To enhance the operation of the solids separator (3), but without causing an additional load on the reactor vessel (1), an additional gas stream (23) independent of the gas stream in the reactor vessel is conducted through the solids separator (3) in a circuit, in the direction of flow of the solids (4).
A process for recycling fine-particle solids (4) discharged by means of a first conveying gas from a reactor vessel (1) at a discharging position of the reactor vessel (1), wherein the fine-particle solids (4) are separated in a solids separator (3), are passed through an exit area (6) of said solids separator (3), are subsequently collected in a collecting vessel (8), and, from said collecting vessel (8), are recycled into the reactor vessel (1) by means of a second conveying gas while maintaining a difference in pressure between the solids separator (3) and an opening in the reactor vessel (1), and wherein a third conveying gas stream (23) is conducted through the solids separator (3) in a circuit towards the collecting vessel (8).
An arrangement for recycling fine-particle solids discharged from a reactor vessel, said arrangement comprising a reactor vessel (1), a gas discharge duct (2) connected to the reactor vessel and leading to a solids separator (3), said solids separator (3) connected to a solids discharge duct (7) for conducting the separated solids (4) from the solids separator (3) to a collecting vessel (8), a solids recycling duct (15) connected to the collecting vessel (8) and leading into the reactor vessel (1), wherein a gas circulating duct (20) is connected in parallel with the solids separator (3) and is provided with a gas injector (21) that sucks off gas from one end of the solids separator (3) and conducts said gas back into the other end of the solids separator (3).
