Problems solved by technology

[0005] The use of compressors for generating the lowest possible desorption pressures is not advantageous because they are not maintenance-free, cause high investment and energy costs, have a high space requirement and also cause high noise load

Embodiment Construction

[0031] The direction of flow is indicated below by arrows.

[0032] exist figure 1 shows a smelting reduction plant for the production of liquid pig iron on the basis of fine ore. If necessary, the fine ore is treated with additives in a cascade consisting of a plurality of pre-reduction reactors 3 (four vortex bed reactors are shown, 2 or 3 vortex bed reactors can also be used optionally). pre-reduced and subsequently loaded into reduction reactor 2. The loaded material is further reduced and preheated in the reduction reactor 2 . However, it is also possible to dispense with further reduction in the reduction reactor 2 , whereby the gas scrubber 4 and the line for the top gas 13 are omitted. The pre-reduction in the pre-reduction reactor 3 or the reduction in the reduction reactor 2 is carried out by means of the reducing gas 9 produced in the melter-gasifier 1, which is introduced into the reduction reaction after dedusting 2 and lead successively through individual pre...

Abstract

The invention relates to a method and an apparatus for separating at least one gaseous component from a waste gas (14) in a plant for producing molten pig iron (24), preliminary molten steel products, or sponge iron. In a first step of said method, a stream of the waste gas (14) penetrates at least one adsorption separator (16) at a first pressure such that most of the gaseous component is separated from the waste gas (14), and in a second step, most of the gaseous component is removed from the adsorption separator (16) at a second pressure that is lower than the first pressure. The aim of the invention is to devise a method and design an apparatus that require no maintenance, low investment and energy costs, and little space. Said aim is achieved by a method in which the second pressure or desorption pressure is generated by at least one jet pump (7), to which a stream of a propellant gas (28) is fed at a third pressure exceeding the second pressure.

Description

technical field [0001] The invention relates to a method and a device for separating at least one gaseous component from exhaust gases of plants for the production of liquid pig iron, liquid steel pre-products or sponge iron. [0002] In particular, the invention relates to a method for separating at least one gaseous component from exhaust gases of plants for producing liquid pig iron, liquid steel pre-products or sponge iron, wherein in a first step The gas stream of the exhaust gas is passed through at least one adsorption separator at a first pressure, whereby the gaseous constituents are largely separated from the exhaust gas, and in a second step the gaseous constituents are separated in a specific The second pressure lower than the first pressure is mostly removed from the adsorption separator. [0003] A device for carrying out such a method has at least one adsorption separator and at least one device for generating a desorption pressure. Background technique [0...
