Embodiment Construction

[0034] exist Figure 1 to Figure 3 The shown device for carrying out a chemical and / or physical reaction between solid material 4 and gas 5, in particular for preheating, cooling and / or calcining fine-grained material, consists essentially of at least one spiral and / or spiral Type tube 1, at least one gas tube 2 connected to the end of the helical and / or spiral tube for discharging gas flow, and solid material tube 3 for discharging solid material and connected to the gas tube.

[0035] The helical and / or helical tube 1 opens into the lower part of the tube 2 forming a separation zone 2a having the same diameter as the part of the gas tube 2 above and adjoining it. The helical and / or helical tube 1 leads tangentially and at an angle α of at least 30° to the horizontal into the separation zone 2a. The angle α is preferably in the range of 30° to 60°.

[0036] The gas pipe 2 , or rather the separation zone 2 a of the gas pipe 2 , further has in its lower region a portion 2 b t...

Abstract

The device according to the invention for performing chemical and / or physical reactions between a solid material and a gas, particularly for preheating, cooling, and / or calcining fine-grained materials, is made substantially of a helical and / or spiral pipe in which the gas-solid suspension is separated into a solid stream and a gas stream by centrifugal forces, and at least one deposition area connected to the end of the helical or spiral pipe, a solid material pipe for removing the solid stream and a gas pipe for removing the gas stream being connected to said deposition area. The depositionarea is formed by a lower part of the gas pipe, the deposition area in the area of the opening of the helical and / or spiral pipe and the part of the gas pipe connecting thereabove having the same diameter. The helical and / or spiral pipe opens to form a twisting flow tangential to and at an angle of at least 30 DEG to the horizontal in the deposition area.

Description

technical field [0001] The present invention relates to an apparatus and method for chemical and / or physical reactions between solid materials and gases, in particular for preheating, cooling and / or calcination of fine-grained materials, and a plant for the manufacture of cement factory equipment. Background technique [0002] In practice, systems are known for preheating, cooling and calcining fine-grained materials, in particular comprising DC heat exchangers and cyclones. In most cases, such plants consist of several stacked stages, with the gas flow being directed through all stages from bottom to top, while solid material is fed to each stage in the opposite direction. [0003] A disadvantage of such systems is that they require enormous headroom and the degree of separation of the cyclones cannot always be met. For example, uncontrolled flows often occur in cyclones, for example at the cyclone inlet, by superposition of the incoming air flow on the swirling flow form...
