Description
Technical Field
The utility model relates to the technical field of distributors, in particular to an air inlet distributor.
Background
The tower is the most common mass transfer equipment in the chemical production process and has important application position in unit operations such as separation, absorption, extraction, reaction and the like. Wherein a plate column and a packed column are the main application forms of the tower equipment. Gas distribution within the column, especially inside large columns, is very important. The uneven distribution of the gas not only causes the mass transfer efficiency on the packing or the tray to be reduced, but also generates a Martian effect due to the bias flow effect to further cause the bias flow of the liquid which originally flows reversely and uniformly with the gas phase, so the design of the gas inlet distributor is an important part for the design of the tower. The air inlet distributor mainly comprises a pipe type distributor, a calandria type distributor, a notch type distributor, a double-row blade type distributor and the like.
The double-row vane type air inlet distributor is a simpler and more reliable air inlet initial distributor. The gas distributor can not only uniformly distribute the gas in the tower, but also has lower pressure drop, small disturbance to the liquid in the tower kettle and convenient installation, and is one of the most common gas distributors. The gas distribution principle of the double-row vane type gas inlet distributor is that after gas enters the distributor, the gas is gradually guided by guide vanes radially arranged on two sides of the distributor, and finally the gas is uniformly distributed on a plane. However, the double row vane inlet distributor does not achieve an overall uniform distribution of the gas within the column.
Therefore, the technical problem that the gas in the tower is distributed unevenly on the whole in the prior art is solved.

The double-row vane type air inlet distributor is a simpler and more reliable air inlet initial distributor. The gas distributor can not only uniformly distribute the gas in the tower, but also has lower pressure drop, small disturbance to the liquid in the tower kettle and convenient installation, and is one of the most common gas distributors. The gas distribution principle of the double-row vane type gas inlet distributor is that after gas enters the distributor, the gas is gradually guided by guide vanes radially arranged on two sides of the distributor, and finally the gas is uniformly distributed on a plane. However, the double row vane inlet distributor does not achieve an overall uniform distribution of the gas within the column.
Therefore, the technical problem that the gas in the tower is distributed unevenly on the whole in the prior art is solved.
To solve the above problems, the present invention provides an intake air distributor.
As shown in fig. 1, an intake distributor provided in an embodiment of the present invention includes an upper baffle 1, a lower baffle 2, horizontal guide vanes 3, and vertical guide vanes 4; a first gas channel is formed between the upper baffle plate 1 and the lower baffle plate 2, and horizontal guide vanes 3 are respectively arranged on two sides of the first gas channel; two sides of the top surface of the upper baffle plate 1 are respectively provided with a side baffle plate 5, and the upper baffle plate 1 and the two side baffle plates 5 surround to form a second gas channel; vertical guide vanes 4 are arranged at the top of the second gas channel.
By adopting the air inlet distributor provided by the embodiment of the utility model, the two sides of the top surface of the upper baffle plate 1 are provided with the side baffle plates 5, so that the upper baffle plate 1 and the two side baffle plates 5 surround to form a second air channel, and the top of the second air channel is provided with the vertical guide vanes 4, so that when air enters the distributor through an air inlet pipeline, the air inlet can be divided into two parts due to the existence of the upper baffle plate 1 of the distributor, namely, the air can respectively enter the first air channel positioned below and the second air channel positioned above, and the air entering the first air channel can be gradually divided along with the horizontal guide vanes 3 arranged radially in the process of advancing forwards, so that the uniform distribution of a two-dimensional horizontal plane is realized; the gas that gets into the second gas passage can be shunted gradually along with the perpendicular guide vane 4 at top at the in-process of marcing, like this also can realize gaseous vertical direction's evenly distributed in the top of distributor overhead gage 1, just also makes gaseous evenly distributed on three-dimensional space that has realized, and the distribution effect is more even, has realized the gaseous evenly distributed on the whole in the tower.
For example, in a tower with the diameter of 4 meters, the gas flow is measured to be 2 ten thousand square per hour, the pipe diameter of a gas inlet pipeline is 600mm, the flow velocity of gas can reach 20m/s, and the gas is difficult to be uniformly distributed at a higher gas flow velocity, so that the packing efficiency of the whole tower is low, and the production requirement cannot be met. By adopting the air inlet distributor provided by the embodiment of the utility model, the actual measurement shows that the flow velocity of the gas in the tower is 0.5m/s after the gas is uniformly distributed by the distributor, the distribution is more uniform, and the efficiency of the whole tower is improved.

In one possible embodiment, the inlet end caliber of the second gas channel is larger than the outlet end caliber. The air pressure in the second air passage can be reduced, so that the caliber of the inlet end is set to be larger, the caliber of the outlet end is set to be smaller, the air pressure can be kept relatively stable, further, any position in the second air passage can be subjected to the same vertical flow guiding effect, and the effect of vertical distribution of air is optimized.
In one possible embodiment, the vertical guide vanes 4 are arranged at a height that gradually decreases from the gas inlet direction to the outlet direction. The channel space in the second gas channel is gradually reduced from the gas inlet direction to the outlet direction, so that the relative stability of the gas pressure in the second gas channel can be kept, and the uniformity of vertical flow guiding is facilitated.
In one possible embodiment, the horizontal guide vanes 3 and the vertical guide vanes 4 are cambered structures. The cambered surface structure has good flow guiding effect, so that gas is uniformly distributed outwards along the concave part in the cambered surface.
