Problems solved by technology
[0003] When the reactor with this structure is in operation, it is found that the reaction efficiency near the center of the inner cylinder is higher than that near the wall of the cylinder, so that there is a large difference in the reaction speed of each reaction zone in the reactor, resulting in There is an area where the reaction temperature is too high in the reaction area, so that the reaction tends to increase the side reaction

Embodiment Construction
[0046] The structure of the air distribution component will be further described below.
[0047] The arrow M marked in the drawings indicates the first axis, and the extending direction of the first axis is called the first axis direction.
[0048] refer to figure 1 , an air distribution member 100, which has a distribution cylinder 10, the distribution cylinder 10 extends along the first axis direction, the distribution cylinder includes an outer plate 12 and an inner plate 11 connected to the outer plate 12, the outer Both the plate 12 and the inner plate 11 extend along the first axis direction, and an air distribution cavity 105 extending along the first axis direction is formed between the outer plate 12 and the inner plate 11, and an air distribution hole is opened on the inner plate 11. Air distribution holes run through the inner and outer sides of the inner panel.
[0049] A lower end plate 21 is installed at one end of the distribution cylinder 10, and this lower e...

The invention discloses a gas distribution piece which can effectively improve the uniformity of reaction in a reactor, the gas distribution piece is provided with a distribution cylinder, the distribution cylinder comprises an outer side plate and an inner side plate connected to the outer side plate, a gas distribution cavity is formed between the outer side plate and the inner side plate, the inner side plate is provided with gas distribution holes, the gas distribution holes penetrate through the inner and outer sides of the inner side plate; one end of the distribution cylinder is a closed end, the other end of the distribution cylinder is a gas inlet end, and a gas inlet communicated with the gas distribution cavity is formed in the gas inlet end; the side face, away from the outer side plate, of the inner side plate forms a first outer surface. The cross section of the inner side plate is in an arc shape protruding in the direction away from the outer side plate. The invention further discloses a reactor using the gas distribution piece. The gas flows exhausted by the two adjacent gas distribution pieces collide and are mixed, so that the distribution uniformity of the gas in the reaction cavity is improved, and the reaction efficiency and the use efficiency of the catalyst close to the gas distribution piece area are improved.
Description
technical field [0001] The invention relates to a gas distribution part and a reactor. Background technique [0002] At present, in the radial reactor, it is necessary to set up a special gas distribution structure so that the raw material gas entering the reactor can evenly enter the catalyst chamber for reaction. The conventional design is to set a The inner cylinder, and the center of the inner cylinder is provided with a gas collector for collecting the gas that has completed the reaction. A catalyst is stacked between the inner cylinder and the gas collector, and an air distribution hole is opened on the inner cylinder, and then between the inner cylinder and the outer shell An annular gap is formed. After the raw material gas enters the annular gap, it enters the catalyst through the gas distribution hole to react, and the gas that completes the reaction enters the gas collector. This structure enables the raw material gas to enter the catalyst along the radial directi...
