Description

Technical Field

[0001] The utility model relates to a reactor, in particular to a cone sleeve type gas distributor. Background Art

[0002] At present, the gas distributor used in large-scale reactors is an arc-shaped baffle. The arc-shaped baffle is installed in the shell of the reactor, located below the air inlet of the reactor and covering the air inlet of the reactor. The arc-shaped baffle is densely covered with conical holes. During use, the air inlet has turbulence and deviation, which will cause uneven gas distribution and affect the reaction effect. Summary of the invention

[0003] In order to solve the above problems, the utility model proposes a cone-sleeve type gas distributor, which has stable air intake and uniform air distribution.

[0004] The technical solution of this utility model:

[0005] A cone sleeve type gas distributor, which is a component of a large reactor and is installed in the shell of the large reactor; the distributor comprises a central tube and a plurality of channels, the upper end of the central tube is open and connected to the air inlet at the top of the large reactor, the lower end of the central tube is sealed by a sealing plate, a plurality of circular holes are evenly distributed on the sealing plate, each channel is installed on the central tube, and is evenly distributed in a circle around the central tube as the center, each channel is tilted downward by 10°~20° (the angle cannot be too large, because a large angle will increase the gas descent speed, and a small angle will slow the descent speed, so that the gas can be stable), its upper port is connected to the central tube, and a plurality of circular holes are evenly distributed at the bottom of each channel.

[0006] The passage is surrounded by four side panels: upper, lower, left and right.

[0007] Each channel has a common upper side plate, and the upper side plate is a cone tube, which is sleeved on the central tube and connected with the central tube; the overall structure is more stable and firm.

[0008] The upper end of the channel is narrow and the lower end is wide. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 This is the front view of the cone-sleeve type gas distributor.

[0010] Figure 2 This is a bottom view of the cone-sleeve type gas distributor.

[0011] In the figure, a central tube 1, a channel 2, circular holes 2-1 distributed at the bottom of the channel, a blocking plate, circular holes 3-1 distributed on the blocking plate, and a conical tube 4 are provided. DETAILED DESCRIPTION

[0012] Figure 1-2As shown, a cone sleeve type gas distributor, the distributor is installed in the shell of a large reactor as a component of a large reactor; the distributor includes a central tube 1 and a plurality of channels 2, the upper end of the central tube 1 is open and connected to the gas inlet at the top of the large reactor, the lower end of the central tube 1 is sealed by a blocking plate 3, and a plurality of circular holes 3-1 are evenly distributed on the blocking plate 3, each channel 2 is installed on the central tube 1, and is evenly distributed in a circle around the central tube 1, each channel 2 is tilted downward by 15°, and its upper port is connected to the central tube 1, and a plurality of circular holes 2-1 are evenly distributed on the bottom of each channel 2;

[0013] The passage 2 is surrounded by four side panels: upper, lower, left and right;

[0014] Each channel has a common upper side plate, and the upper side plate is a cone tube 4, which is sleeved on the central tube 4 and connected to the central tube 4;

[0015] The channel 2 has a narrow upper end and a wide lower end.

[0016] When the cone sleeve type gas distributor is used, gas enters from the upper port of the central tube 1, a small part of the gas goes out from the circular holes on the blocking plate 3, and most of the gas enters each channel 2 and goes out from the lower port of each channel 2 and the circular holes at the bottom.

[0017] The above embodiments are only for illustrating the technical concept and features of the invention, and their purpose is to enable people familiar with the technology to understand the content of the invention and implement it accordingly, and they cannot be used to limit the protection scope of the invention. Any equivalent changes or modifications made according to the spirit of the invention should be included in the protection scope of the invention.
