Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy saving, in particular to a gas cross-flow spray heat exchange device. BACKGROUND

[0002] The packed tower is a device frequently used in industrial engineering, which is used for gas and liquid to fully contact in the tower to occur heat and mass transfer. The conventional packed tower is a vertical structure, the gas enters the tower from the bottom, flows from bottom to top, and is finally discharged from the top. The liquid is sprayed from the top of the tower, then enters the packing zone, fully contacts with the gas on the packing surface in the packing zone to occur heat and mass transfer, and then flows into the bottom to be collected. The flow directions of the liquid and the gas are countercurrent, which is beneficial to the occurrence of heat and mass transfer.

[0003] However, the conventional packed tower is generally a cylindrical vertical structure, which stands on the ground, and its height is limited by the total length required by the flue gas diffusion zone, the packing zone, the spray expansion zone, the spray pipe zone, the demister zone, and the maintenance zone. Therefore, the conventional packed tower needs a very sufficient space in the height direction.

[0004] When the height space of the installation site is limited, a cross-flow tower is generally needed, that is, the gas enters and exits horizontally, the liquid flows vertically, and the gas and the liquid flow in the opposite direction in the packing zone. However, the conventional cross-flow tower has the following disadvantages: the gas blows to the packing, the liquid flow in the packing zone will be deflected under the blowing of the gas, resulting in that part of the packing does not participate in the heat and mass transfer. The gas and the liquid always flow in the opposite direction, and the heat transfer efficiency is reduced. In addition, the conventional cross-flow tower cannot meet the working conditions that must occur countercurrent heat and mass transfer. SUMMARY

[0005] Based on the above-mentioned deficiencies, the present application provides a gas cross-flow spray heat exchange device to partially or completely improve the problem of low heat exchange efficiency of the cross-flow tower in the related art.

DETAILED DESCRIPTION

[0039] The embodiments of the technical solutions of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0042] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive or alternative embodiments. It is expressly understood that the embodiments described herein are combinable with each other.

[0043] In the description of the embodiments of the present application, the technical terms "upper", "lower", "top", "bottom", "inner" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the embodiments of the present application.

[0044] The packed column is a device frequently used in industrial engineering, which functions to fully contact gas and liquid in the column to occur heat and mass transfer. The conventional packed column has a vertical flow column and a horizontal flow column. The gas flow and liquid flow in the vertical flow column are in countercurrent relationship, and the heat exchange effect is good. However, the vertical flow column needs sufficient space in the height direction, and the gas inlet and outlet are not at the same height. If the gas needs to be flatly introduced and flatly discharged, a flue needs to be designed to guide the gas from the top to the lower part. The on-site installation of the device is difficult, and a sufficient climbing ladder, support, maintenance platform and many auxiliary materials need to be set.

[0045] The height of the conventional horizontal flow column is relatively low, but in the horizontal flow column, the liquid flows vertically downward, and the gas flows horizontally. The gas and liquid flow in the wrong direction in the packed area. The conventional horizontal flow column has the following disadvantages: the gas blows to the packing, the liquid flow in the packing area will be deflected under the blowing of the gas, resulting in that part of the packing does not participate in the heat and mass transfer. The gas and liquid always flow in the wrong direction, not in the reverse direction, and the heat transfer efficiency will be reduced. In addition, the horizontal flow column cannot meet the working conditions which must be countercurrent heat and mass transfer.
