摘要： A method and apparatus for heating cellulose pulp with steam are provided. Low-pressure (e.g. 3-5 bar (abs.)) steam is supplied into the pulp flowing as a plug flow in such a way that in the flow direction of the pulp, before supplying the low-pressure steam, the pulp is pressurized so that the pulp pressure at the point of the steam introduction is lower than the pressure of the available steam. After the steam is introduced the pulp is mixed with a pressure-raising mixer (such as a fluidizing centrifugal pump) to divide the steam evenly into the pulp and/or to equalize the temperature of the pulp.

摘要： A method and apparatus allow large volumes of gas (at least about 10% by volume) to be mixed into a cellulosic fiber suspension having a consistency of about 8-25%. The mixing of ozone containing gas into the suspension is particularly desirable. The suspension is passed into the inlet of a mixer, gas is introduced into the mixer, and the gas and fiber suspension are homogenized by fluidizing the gas and suspension. The flow of suspension through the mixer is throttled so that the effect of the fluctuation and pressure between the inlet and outlet is minimized, and the homogeneously mixed gas and fiber suspension mixture is discharged from mixer outlet. The mixer may have a premixing zone in which the gas and suspension are fluidized to the floc level and the gas is evenly distributed throughout the suspension, then a homogenization zone in which the fiber suspension is fluidized to fiber or microfloc level and the gas is brought into contact with each fiber or microfloc, and then a maintenance zone in which the fluidization level is maintained high enough to prevent the generation of gas bubbles and the separation of gas from the suspension.
摘要翻译：一种方法和装置允许将大体积的气体（至少约10体积％）混合到具有约8-25％的稠度的纤维素纤维悬浮液中。将含臭氧气体混入悬浮液是特别理想的。将悬浮液送入混合器的入口，将气体引入混合器中，并通过使气体和悬浮液流化使气体和纤维悬浮液均化。通过混合器的悬浮液的流动被节流，使得入口和出口之间的波动和压力的影响最小化，并且均匀混合的气体和纤维悬浮液混合物从混合器出口排出。混合器可以具有预混合区域，其中气体和悬浮液被流化到絮状物水平并且气体均匀分布在整个悬浮液中，然后是均匀化区域，其中纤维悬浮液被流化为纤维或微环境水平并且气体被带入与每个纤维或微团接触，然后是维持区，其中流化水平保持足够高以防止产生气泡和气体与悬浮液分离。

摘要： Gas is separated from fluent material, particularly a liquid or a cellulose fiber suspension having a consistency of about 8-18%, utilizing a closed separation apparatus having a spiral housing with a central axis, a fluent material inlet channel, a fluent material outlet, and a gas outlet. A pressure differential is maintained between the inlet channel and the spiral housing, and the pressure differential is converted to kinetic energy of the fluent material by causing the fluent material to flow through one or more spiral flow paths through the inlet channel toward the spiral housing. In the spiral housing a rotor is rotated to impart a strong centrifugal force to the fluent material to cause gas to separate and collect adjacent the central axis of the spiral housing, from which the gas is removed. The strong centrifugal force caused by the rotating rotor discharges the fluent material through the outlet. The spiral flow paths rotate with the rotor in the spiral housing.

摘要： The present invention relates to a mixing of gas into a medium. The method and apparatus in accordance with the present invention are especially applicable in the bleaching plants of the wood processing industry for mixing gaseous bleaching chemicals into pulp and to bleaching process of pulp, in which the mixing method and apparatus in accordance with the present invention are applied. An excellent application is mixing ozone-containing gas into a fiber suspension flowing in a pipe line and an ozone bleaching process. The previously known methods and apparatuses have not been able to mix satisfactorily large volumes of gas, about 50% of the total volume of the flow, into the medium flow. In the method in accordance with the present invention the mixing is carried out in a strong shear force field efficiently and uniformly, whereafter the fiber network of the medium is allowed to form rapidly and in a controlled manner so that gas is not allowed to separate in the flow as bubbles, but remains in the plug flow in the fiber network.
