Reactor, gasliftpomp voor in een reactorvat, alsmede werkwijze voor het uitschakelen van een reactor.

摘要

The invention relates to a reactor and also to a gas lift pump for said reactor. The reactor comprises a reactor vessel provided with fluid conta ining therein a bed of particle material. The reactor further comprises the gas lift pump according to the invention, which is arranged in the reactor vessel. The gas lift pump comprises a vertical first tube (inner tube) having an open underside and upper side, and also a mouthpiece for blowing in a gas. The open underside of the first tube (inner tube) lies in the bed of particle material. The mouthpiece is provided at the underside of the first tube (inner tube) in such a way that blowing gas into the fi rst tube (inner tube) brings about a reduction in the density of the fluid. The gas lift pump further comprises a second tube (outer tube) having an open underside and an open upper side. The underside of the second tube (outer tube) lies concentrically ar ound the underside of the first tube (inner tube) to produce a concentric channel at this location.
