[0027] As shown in Figure 1 , Figure 2 and Figure 3 , a kind of multi-channel chemical gas uniform distribution flow guide device, comprising: through pipe 20, through pipe 20 is hollow rectangular channel with front wall surface open, this is prior art, so not elaborated here.

[0028] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , converging-diverging structure, converging-diverging structure is arranged on the wall surface of through pipe 20 for gas converging and flow distribution, and converging-diverging structure includes: external connection pipe 30, flow collecting cone 31, spoiler 37 and flow distribution plate 35, external connection pipe 30 is fixedly connected at the top of rear wall surface of through pipe 20, flow collecting cone 31 is fixedly connected in the cavity rear wall surface of through pipe 20, spoiler 37 is fixedly connected in the cavity of through pipe 20, and flow distribution plate 35 is fixedly connected on the front wall surface of through pipe 20.

The air baffle 32 is fixedly connected to the front wall of the collecting cone 31, the tail sieve plate 33 is fixedly connected to the front wall of the air baffle 32, the front plate 34 is fixedly connected to the front wall of the flow divider 35, and the head sieve plate 36 is fixedly connected to the rear wall of the flow divider 35. The air baffle 32 is a right trapezoidal plate, the same air baffles 32 are uniformly arranged on each edge of the collecting cone 31, the end of the outer connecting pipe 30 is aligned with each adjacent air baffle 32, the tail sieve plate 33 is an isosceles triangular plate, a plurality of round holes are uniformly arranged on the front wall of each tail sieve plate 33, and the same tail sieve plates 33 are arranged between the front walls of each adjacent air baffle 32.

[0030] In specific use, each outer connecting pipe 30 is communicated with the gas outlet pipe of each chemical device. When the chemical gas is introduced into the outer connecting pipe 30, the chemical gas will be concentrated in the cavity of the through pipe 20 through the outer connecting pipe 30. When the chemical gas enters the cavity of the through pipe 20 through the outer connecting pipe 30, it will first contact the inclined surface of the collecting cone 31, then flow between the adjacent air baffles 32 through the inclined surface of the collecting cone 31 to the tail sieve plate 33, and then move towards the spoiler 37 after passing through the round holes on the wall of the tail sieve plate 33.

[0034] In summary, by arranging the spoiler tube 38, the flow rate of the gas in the cavity of the through pipe 20 can be further slowed down by using the backflow of the gas when the gas passes through the spoiler plate 37, so that the uniformity rate during uniform distribution of the gas is improved.

[0035] Working principle: when the chemical gas is introduced into the external connecting pipe 30, the chemical gas will be concentrated in the cavity of the through pipe 20 through the external connecting pipe 30, and the chemical gas will first contact the inclined surface of the flow collecting cone 31 when passing through the external connecting pipe 30 and entering the cavity of the through pipe 20, then flow between adjacent gas separation plates 32 through the inclined surface of the flow collecting cone 31 to the tail sieve plate 33, and then move towards the spoiler plate 37 after passing through the round holes in the wall surface of the tail sieve plate 33, at this time, the gas in the cavity of the through pipe 20 will pass through the spacing between each spoiler plate 37, at this time, the flow rate of the gas in the cavity of the through pipe 20 will be greatly reduced, and finally the gas will pass through the round holes in the wall surface of the head sieve plate 36 and uniformly flow out of the opening of the flow dividing plate 35.
