However, since each tray of the purification tower is a single-layer orifice plate, the contact time between the flue gas and the absorption liquid is extremely short, and the action area is only in a small range around the orifice, so the gas-liquid provided The contact strength is low; in order to ensure the structural strength of the tray, the opening ratio of the orifice plate is limited to a certain extent, and the flue gas needs to pass through the small holes of each tray, resulting in large system resistance; in addition, due to the reaction of the above trays The zone is located around the small hole, if it forms a solid precipitate with the reactant, it is easy to deposit on the edge of the hole, which may cause blockage after a period of use, and the failure rate increases, which makes the operation and maintenance costs of the purification tower higher

Embodiment 1
[0047] In this embodiment, such as figure 2 Show, part of the edge 411 of the reaction hole board 41 is connected to the inner wall of the reaction tower body 1, and the other edge 412 is retained with a certain distance from the inner wall of the reaction tower 1.Entrance 42 or wrong export 43.In this example, the size of the spacing of the error flow into the library 42 or the export 43 of the error flow should be ensured that the adjacent reaction hole board 41 is overlap, which is suitable for one -half of the area of less than the area of the reaction hole board.
[0048] Improve the effect of absorption reaction.
[0049] Example 2
Embodiment 2
[0051] In this embodiment, such as Figure 7-12 Show, the cone -shaped reaction hole board 41 can be a positive cone -shaped reaction hole board with a large end 414 upward.Of course, the cone -shaped reaction hole 41 can also be a large -end 414 inverted cone reaction hole board, which is not shown in the figure.
[0052] In this embodiment, such as Figure 6 Show, the cone -shaped reaction hole board 41 can be composed of multiple fan -shaped reaction holes.
[0053] In this embodiment, such as Figure 7 It is shown that the support pillar 7 is set at the center axis position of the reaction tower body 1 to increase the radial distance of the error flow entrance 42 and the error flow export 43, thereby increasing the flow distance between the gas between the adjacent reaction hole board 41 41, Further improve the effect of absorption.
[0054] Example 3
Embodiment 3
[0056] In this embodiment, such as Figure 17 Show, the two or more reaction holes 41 can be connected to a horizontal bracket 7, which can be connected to the inner wall of the reaction tower body 1, thereby supporting the multi -block reaction hole board 41 supportIn the reaction tower body 1.
[0057] In this embodiment, such as Figure 16 Show, the horizontal end of the flat -shaped reaction hole 41 can be connected to the inner wall of the reaction tower body 1.
[0058] As a specific example, such as figure 1 The multi -layer liquid inlet in the present invention can be formed by the atomized nozzle head 5. When used, the absorption solution is sprayed into the reaction tower 1 through the atomized nozzle head 5.
[0059] Using the above structure, the wrong current absorption reaction device of the present invention has functions such as decentralization, liquid holding, and energy storage.It can provide huge comparison area and high relative atmospheric speed between two or ...

Abstract
The invention relates to a cross-flow absorption reactor, comprising a reaction tower body. An air inlet is arranged on the lower section of the reaction tower body. An air outlet is arranged on the upper section of the tower body. A multilayer liquid inlet nozzle is arranged on the central section of the tower body. A set of or more than a set of cross-flow plates are arranged at the interval inthe height direction inside the reaction tower body, wherein, a set of cross-flow plates comprise two or above two reaction orifice plates. A gap left between neighboring reaction orifice plates. A cross-flow space is formed from the gap. A cross-flow inlet for cross flow entering the cross-flow space is arranged on the lower section of the cross-flow space. A cross-flow outlet for cross flow flowing out is arranged on the upper section of the cross-flow space. The cross-flow inlet and the cross-flow outlet are staggered on the radial direction of the reaction tower body. The cross-flow absorption reactor has the advantages of high absorption coefficient, small system resistance, not frequent plugging, and low cost for maintenance.
Description
Technical field [0001] The present invention involves an absorption reaction device for environmental pollutioncontrol engineering, chemical, pharmaceutical and other fields. Specifically, it is a device of a wrong current absorption reaction. Background technique [0002] At present, the flue gas purification devices for industrial kiln, coal -fired boilers, and chemical production facilities include, impact or self -intensive purifiers, mochi water film purification tower, spinning plate tower, sieve pagoda, etc.Its purification rate for dust can reach 90-98 %, but the capture rate of fine particles and charcoal black in the dust of smoke is very low; the purification rate for harmful gases can only reach 60-85 %.It still causes some harm.In order to improve the purification rate, a patented patent number of 02259890.1 proposed a dust and harmful gas purification tower, which mainly set up a five -layer tower board from the bottom to the last equivalence of the inlet of the pu...
