Claims
- 1. A liquid distributor for use inside a substantially vertical reactor containing a fixed bed catalyst wherein the liquid distributor is in the form of a channel distributor containing a main channel with side channels connected thereto and further comprising at least one drainage outlet, a liquid feed pipe fitted into said main channel, and a cleaning mechanism comprising a holder contained within a guide for vertical displacement, wherein the holder consists of a main support positioned in said main channel, lateral supports attached to the main support and extending inside said side channels, and at least one cleaning element capable of being lowered into the opening or openings of the at least one drainage outlet.
- 2. The distributor of claim 1 wherein said cleaning element is a pin.
- 3. The distributor of claim 1 wherein said cleaning element is suspended from said holder by a spring.
- 4. The distributor of claim 3 wherein an additional spring retains said holder and cleaning element in an upper position, relative to the distributor drainage outlet, and an actuating device depresses said holder and cleaning element, whereby said cleaning element is lowered into said drainage outlet.
- 5. The distributor of claim 4 wherein said actuating device is pneumatically driven.
- 6. The distributor of claim 4 wherein the position and spring constant of said springs are coordinated such that said holder and cleaning element will not jam within said guide under uneven depression.
- 7. A substantially vertical reactor containing a fixed bed catalyst and a liquid distributor positioned in the reactor, wherein the liquid distributor is in the form of a channel distributor containing a main channel with side channels connected thereto and further comprising at least one drainage outlet, a liquid feed pipe fitted into said main channel, and a cleaning mechanism comprising a holder contained within a guide for vertical displacement, wherein the holder consists of a main support positioned in said main channel; lateral supports attached to the main support and extending inside said side channels, and at least one cleaning element capable of being lowered into the opening or openings of the at least one drainage outlet.
- 8. A liquid distributor adapted for use inside a substantially vertical reactor containing a fixed bed catalyst wherein the liquid distributor is in the form of a channel distributor comprising a drainage outlet and having a cleaning mechanism comprising a cleaning element which can be lowered into the opening of said drainage outlet, and wherein the cleaning element is attached to a holder, said holder contained within a guide for vertical displacement.
- 9. A substantially vertical reactor containing a fixed bed catalyst and a liquid distributor positioned in the reactor, and adapted for use therein wherein the liquid distributor is in the form of a channel distributor comprising a drainage outlet and having a cleaning mechanism comprising a cleaning element which can be lowered into the opening of said drainage outlet, and wherein the cleaning element is attached to a holder, said holder being contained within a guide for vertical displacement.
- 10. A liquid distributor adapted for use inside a substantially vertical reactor containing a fixed bed catalyst wherein said distributor is designed to be positioned in the reactor and said distributor is in the form of a channel distributor containing a drainage outlet and a cleaning mechanism containing at least one pin for cleaning the drainage outlet.
