초록 ▼

A system and method for feeding comminuted cellulosic fibrous material such as wood chips to the top of a treatment vessel such as a continuous digester provide enhanced simplicity, operability, and maintainability by eliminating the high pressure transfer device conventionally used in the prior art. Instead of a high pressure transfer device the steamed and slurried chips are pressurized using one or more slurry pumps located at least thirty feet below the top of the treatment vessel and for pressurizing the slurry to a pressure of at least about 10 bar gauge. A return line from the top of the digester may, but need not necessarily, be operatively connected to the one or more pumps and if connected to the pumps the pressure in the return line may be reduced utilizing a pressure reduction valve and/or a flash tank. Steam from the flash tank may be used in steaming the chips. Pressure relief prevention may be provided by isolation valves in the lines leading to and from the top of the treatment vessel controlled by a controller which is responsive to the pressure sensed in the slurry line leading to the top of the treatment vessel.

대표청구항 ▼

[ What is claimed is:] [1.] A system for producing chemical cellulose pulp from comminuted fibrous cellulose material, comprising:a steaming vessel in which comminuted fibrous cellulose material is steamed to remove the air therefrom;a superatmospheric pressure vertical treatment vessel having an inlet for a slurry of comminuted cellulose fibrous material at a top portion thereof and an outlet at a bottom portion thereof; andpressurizing transfer means for pressurizing a slurry of material from the steaming vessel and transferring it to said treatment vessel inlet, said pressurizing transfer means consisting of one or more high pressure slurry pumps located below said top portion of said treatment vessel.
