摘要:
A reactor for anaerobically purifying waste water, such as waste water from the paper industry, includes a reactor vessel that has at least one inlet for supplying waste water to be purified into the reactor, at least one outlet for discharging purified water, at least one sediment filter and at least two multi-phase separator devices arranged on top of one another.

A reactor for biological purification of waste water includes a reactor vessel having a substantially flat or a round bottom, at least one supply pipe arranged in a lower region of the reactor vessel for feeding the waste water to be purified into the reactor, at least one fluid discharge pipe for discharging purified waste water from the reactor, at least one solid matter discharge pipe arranged in the lower region of the reactor vessel for discharging solid matter from the reactor and at least one diverting means including at least one diagonally extending section. The at least one diverting means is designed and/or arranged so that solids sinking to the bottom of the reactor from the upper region of the reactor are deflected so that the solids settle in a region of the at least one solid matter discharge pipe and are discharged from the reactor through the at least one solid matter discharge pipe.

摘要:
The invention relates to a reactor for anaerobically purifying waster water, especially waste water from the paper industry, comprising a reactor vessel, several inlets arranged in the bottom region of the reactor vessel to feed waste water to be purified into the reactor, at least one outlet for discharging purified water, and at least one sediment drain. One or more inlets are fed by a supply pipe, and several supply pipes are fed by a collecting supply pipe. In order to ensure that waste water to be purified is fed as regularly as possible at the bottom of the reactor vessel, at least the majority of the supply pipes of a collecting supply pipe supply waste water to be purified to a maximum of 10 inlets, and at least the majority of said supply pipes each have a control valve.

A process and apparatus serves to remove solid matter from an aqueous material suspension produced from printed used paper. As many interfering material particles are collected by floatation as possible in a floatation foam and diverted as a reject. A perforated separating element is located above the fibrous material suspension. Between the separating element and the floatation foam, an intermediate layer is formed. In the intermediate layer the fibers, which have been entrained by gas bubbles are again rinsed and retrieved.
摘要:
Process and decker for bringing together a first aqueous pulp suspension layer with at least one additional suspension layer. The process includes moving the first pulp suspension layer and the at least one additional suspension layer on moving layer supports, and guiding sides of the first pulp suspension layer and the at least one additional suspension layer that are adapted to contact each other on guiding surfaces that are one of stationary and limitedly moving. The guide surfaces include contoured surfaces arranged to run substantially parallel to the layer supports. The process further includes applying the at least one additional suspension layer onto the first pulp suspension layer at a wedge-shaped gap, and draining the first pulp suspension layer and the at least one additional suspension layer. The decker includes at least one rotating cylinder, and an endless wire guided around at least a portion of an outer circumference of the at least one rotating cylinder. The at least one rotating cylinder and the endless wire form a wedge-shaped gap. The decker also includes a first suspension introducing device for introducing a first suspension layer into the wedge-shaped gap, a displacer arranged upstream from the wedge-shaped gap that includes first and second guide surfaces, in which the first guide surface is arranged to be substantially parallel to a portion of the outer circumference of the at least one rotating cylinder adjacent thereto and the second guide surface is arranged to be substantially parallel to a portion of the endless wire adjacent thereto. At least one second suspension introducing device for introducing at least one second suspension layer into the wedge-shaped gap is also provided. The at least one second suspension introducing device is positioned to introduce the at least one second suspension layer upstream of the wedge-shaped gap and between the at least one rotating cylinder and the displacer.

A process for draining a fibrous pulp web is preferably carried out on drum thickeners or disk filters. A suspension to be drained rests against a perforated first face, which is a part of the rotor of the drum thickener or disk filter, is transported from the suspension vat, and then arrives in a thickening region. The thickening region contains a second face, wherein the first and second face have a relative speed in relation to each other. The effectiveness of the thickening can be significantly increased by vacuum zones provided on the drum thickener or disk filter.
摘要:
An apparatus and method serves, e.g., to deaerate, clean or screen a fibrous suspension and is provided with a closed housing and a rotor arranged centrally therein. The rotor puts at least a part of the fibrous suspension guided into the housing into a rotational flow. The fibrous suspension flowing into the housing through the inlet is put into rotation by a guide element acting hydraulically. This increase the efficiency of the apparatus and prevents disturbing turbulences in the apparatus.
