Embodiment 1

[0043] Such as figure 1 As shown, a gas purification device includes a housing 1, the housing 1 is provided with an air inlet 11 and an air outlet 12, and the top and bottom of the housing 1 are respectively provided with a filling inlet 13 and a filling outlet 14 ; The housing 1 is provided with at least one primary packing channel 2 that allows the packing to flow, and the primary packing channel 2 is connected to the packing inlet 13, the packing outlet 14, the air inlet 11 and the The gas outlet 12 is connected; the filler in the primary filler channel 2 moves from the filler inlet 13 to the filler outlet 14 . The first-stage packing channel 3 may be provided with several air outlets, and the air outlets communicate with the air outlet 12 ; The hole diameter of the air outlet is set to be smaller than the particle size of the filler to avoid leakage of the filler through the air outlet.

[0044] The dust-laden dust-laden gas enters the first-stage packing channel from th...

Embodiment 2

[0059] The temperature of the dusty gas treated in this example is 500°C, and the dust concentration is 40g / m 3 ; The filler is magnesium aluminum spinel, and its temperature is 300°C;

[0060] This embodiment provides a method for gas purification, including:

[0061] Flow the dusty gas at 10m / s 2 The air velocity through the flow velocity is 2m / s 2 Filler, wherein the mass volume ratio (g / mL) of the amount of filler to high-temperature gas is 10:1, and the flow direction of the dusty gas is perpendicular to the flow direction of the filler.

[0062] The dust concentration in the dust-containing gas after dust removal is detected to be 6g / m 3 .

Embodiment 3

[0064] The temperature of the dusty gas treated in this example is 300°C, and the dust concentration is 40g / m 3 The filler used in the first filler channel is porous ceramics, the filler used in the second filler channel is aluminum oxide, and the filler in the third filler channel is cordierite; in the first, second and third filler channels The temperature of the filler is 400°C; the gas purification device in which two partitions are arranged in parallel in the second embodiment in Example 1 is adopted;

[0065] include:

[0066] Flow the dusty gas at 10m / s 2 The air velocity enters the shell from the air inlet and is discharged from the air outlet; the flow velocity of the packing in the first, second and third packing channels is 1m / s 2 The filler, wherein the mass volume ratio (g / mL) of the filler in the first, second and third channels to the high-temperature gas is 3:1.

[0067] The dust concentration at the gas outlet is 5g / m 3 .

Abstract

The invention provides a gas purification device. A first-grade filler channel for allowing filler to pass is arranged in a shell body, so that high-temperature dust-containing gas passes through theflowing filler and the filler collides with dust in the dust-containing gas; the dust is adsorbed through the filler, so that the dust is separated from the gas and is discharged along with the filler. Meanwhile, the filler moves to a filler outlet through a first-grade filler inlet; the problem that the dust is adsorbed on a side wall of the first-grade filler channel or is accumulated in the first-grade filler channel so that the filler channel is blocked is effectively avoided through the movement of the filler; the gas purification device is simple in structure and easy to maintain; the dust can be discharged to the outer part of a dust remover in time and the defect that excessive dust is accumulated in the dust remover to cause explosion can be overcome.

Description

technical field [0001] The invention relates to the technical field of gas purification, in particular to a device and method for purifying and dedusting high-temperature gas. Background technique [0002] Dust refers to solid particles suspended in the air, whose particle size is generally less than 75 μm, which can be suspended in the atmosphere for a long time, and is one of the main sources of air pollution. The main sources of dust in the atmosphere are industrially formed dust and naturally formed dust. The industrial dust often contains a large amount of heavy metals such as cadmium, manganese, chromium, etc., which is more harmful to the human body. Studies have shown that long-term exposure of human beings to high levels of industrial dust can cause severe respiratory diseases, cardiovascular diseases and increase the risk of cancer. Therefore, it is very important to reduce the amount of industrially formed dust in the atmosphere. [0003] An important source of...
