Embodiment 1

[0025] Gas-solid separation device, such as figure 1 As shown, the upper reactor and the lower reactor are sequentially connected to a repeated combination of three inclined planes 1 and vertical channels 2, the angle between the inclined plane and the horizontal plane is 40 degrees, and a gas channel 3 is connected to both ends of each inclined plane , screens 4 are provided at the openings of the gas passages 3 . The length of the slope 1 is 4m, and the length of the vertical channel 2 is 1m.

Embodiment 2

[0027] A gas-solid separation device used between a fuel reactor and a steam reactor, such as figure 2 As shown, between the fuel reactor and the steam reactor, the first inclined plane 11, the first vertical passage 21, the second inclined plane 12 and the second vertical passage 22 are connected in sequence, and the upper end of the first inclined plane 11 is connected with the second A gas channel 31, its lower end is connected with the second gas channel 32, the upper end of the second slope 12 is connected with the third gas channel 33, its lower end is connected with the fourth gas channel 34, each gas channel at the channel mouth A screen 4 is provided. The angle between the first inclined plane 11 and the second inclined plane 12 and the horizontal direction is 30 degrees, and their lengths are both 5 m; the lengths of the first vertical passage 21 and the second vertical passage 22 are both 2 m.

Embodiment 3

[0029] In the method of gas-solid separation using the gas-solid separation device of Example 2, after the reaction of the fuel in the fuel reactor and the oxygen carrier is completed, the oxygen carrier is reduced, and it enters the first slope 11 through the lower outlet of the reactor, where the mixed Part of the fuel gas and generated gas are fed into N from the first gas passage 31 2 , drawn from the second gas channel 32, N 2 The throughput is 0.1L / min. The pressure P at the lower outlet of the fuel reactor 2 is 0.1Mpa, so keep the pressure P at the inlet of the first gas channel 31 1 is 0.15Mpa; after the gas-solid separation of the first slope, the oxygen carrier enters the second slope 12 through the first vertical channel 21, and at the same time passes into H from the third gas channel 33 2 , drawn from the fourth gas channel 34, H 2 The amount of feed is 0.1L / min, and the pressure P4 at the inlet of the steam reactor is 0.18Mpa, so the pressure P at the inlet o...

Abstract

The invention relates to a gas-solid separation device and method. The device comprises N repeated combinations of sequentially and alternately connected inclined planes and vertical channels, whereinthe N is more than or equal to 2, wherein the included angle between the inclined plane and the horizontal plane is 20-70 degrees, and two ends of each inclined plane are both connected with a gas channel. The gas-solid separation device is used for gas-solid separation between two reactors which are distributed at upper and lower positions; when a gas-solid product needing to be separated pass through a bevel, nitrogen or inert gas is introduced, and the gas-solid separation is realized by a plurality of times of circulation. The gas-solid separation device is particularly suitable for the gas-solid separation among a fuel reactor, a steam reactor and an air reactor in the chemical-chain hydrogen production technology. The gas-solid separation device has ingenious design, simple structure and suitability for gas-solid separation between reactors at upper and lower positions, good separation effect can be achieved through multiple-stage separation, no gas mixing occurs between the reactors, the difficult problem of gas-solid separation is effectively solved, and the utilization rate and the overall reaction efficiency of the reactors are improved.

Description

technical field [0001] The invention relates to a gas-solid separation device and method, in particular to a high-temperature gas-solid separation device between upper and lower reactors. Background technique [0002] In the process of modern industrial production, there are a wide range of fields involving high-temperature gas-solid separation, such as high-temperature reaction gases in petrochemical and chemical industries, high-temperature gas from blast furnaces and converters in metallurgical industries, high-temperature tail gas in the glass industry, high-temperature waste gas from boilers and incinerators, polysilicon Synthesis gas for synthesis furnaces, etc. There are two types of high-temperature gas-solid separation technology: one is high-temperature direct dust removal, such dust removal technologies include cyclone dust removal, particle layer filtration, filter dust removal, etc.; the other is through spray cooling, heat exchange, etc. Lower the temperature ...
