Embodiment Construction

[0072] figure 1 A process stream 16 for introducing chemicals and / or additives into a manufacturing process according to the invention is shown in a schematic illustration (see also Figure 6 to Figure 8 ) of an exemplary embodiment of the nozzle device 14 comprising a plurality of mixing and / or reaction zones 10 1 、10 2 The base part 12 of , wherein the manufacturing process can be especially a process for manufacturing paper fibers or nonwoven fibers. Here, individual mixing and / or reaction zones 10 can be 1 、10 2 At least two media 28, 54 are provided to be mixed and / or chemically reacted with each other.

[0073] as from Figure 6 to Figure 8 As is known in the art, the nozzle arrangement 14 may comprise a throttle device 20 arranged in the region of the nozzle outlet 18 .

[0074] In this case, the nozzle arrangement 14 comprises, for example, two mixing and / or reaction zones 10 arranged one behind the other when viewed in the main flow direction 22 1 、10 2 .

Abstract

Specified is a method for introducing chemicals and / or additives into a process flow of a production process, in particular of a process for producing a fibrous or nonwoven web, by means of a nozzle arrangement, in which method use is made of a nozzle arrangement having at least one mixing zone and having a throttle device arranged in the region of the nozzle outlet opening, the flow characteristic of which nozzle arrangement is variable and / or which nozzle arrangement can, for variability of the flow characteristic in the region of the nozzle outlet opening, be exchanged for a respective different throttle device with a different flow characteristic, in each case two media are mixed with one another in a respective mixing zone, and to set different flow speeds of the mixture flow which emerges from the nozzle outlet opening and which is to be introduced into the process flow, the flow characteristic of the throttle device is in each case correspondingly varied or a respective throttle device is exchanged for a throttle device with a different flow characteristic. Also specified is a nozzle arrangement for carrying out a method of said type.

Description

technical field [0001] The invention relates to a method for introducing chemicals and / or additives by means of a nozzle arrangement into a process stream of a production process, in particular for producing a fibrous or nonwoven web. The invention further relates to a nozzle arrangement, in particular for carrying out the method. Background technique [0002] In particular the rising costs of energy, raw materials, fresh water and chemicals require their efficient use. Especially in the manufacture of fibrous or nonwoven webs, the consumption of process chemicals and functional chemicals and the use of fresh water as a dilution medium in the preparation of chemicals can be achieved by providing effective method and significantly reduced. [0003] The principles currently used in the dosing of fluid chemicals in process streams for the production of paper or nonwoven webs also have the disadvantage that the chemical concentration is not adjustable in the nozzles and instea...
