Example Embodiment

[0021] Such as Figure 1-3 As shown, the present invention includes a housing 1, in which two layers of horizontally arranged cold walls 10 are arranged to divide the inner cavity of the housing 1 into an upper cold flow zone 6, a hot flow zone 8, and The lower cold flow zone 7, the hot flow zone 8 between the upper cold flow zone 6 and the lower cold flow zone 7, can better utilize the heat of the hot liquid in the hot flow zone 8 and reduce heat loss; In the zone 6, the hot flow zone 8 and the lower cold flow zone 7, a plurality of partitions 9 are arranged side by side along the direction of fluid flow. The partitions 9 separate the upper cold flow zone 6, the hot flow zone 8 and the lower cold flow zone 7 It is divided into multiple parallel channels, which can increase the flux, improve the liquid flow state, facilitate the mass transfer process, and improve the efficiency of membrane distillation, and it is arranged in the form of cold runner-hot runner-cold runner up and...

Abstract

The invention provides an efficient membrane distillation assembly for desulfurization wastewater treatment. The efficient membrane distillation assembly comprises a shell, an upper cold flow area, ahot flow area, a lower cold flow area, a partition plate, a porous hydrophobic membrane, an air gap channel, fins, a cooling water inlet pipeline, a cooling water outlet pipeline, a hot feed liquid inlet pipeline and a hot feed liquid outlet pipeline. According to the invention, the fins are arranged in the air gap channel, so that the water vapor condensation effect can be enhanced, the supporting effect on the porous hydrophobic membrane can be achieved, the curvature of the porous hydrophobic membrane is reduced, and the flux loss is reduced; the partition plates is adopted to divide the upper cold flow area, the hot flow area and the lower cold flow area into a plurality of parallel flow channels; moreover, the flux can be increased, the state of poor liquid flow caused by a large plane is improved, the liquid flow state is promoted, the mass transfer process is facilitated, the membrane distillation efficiency is improved, and the condensation of water vapor is promoted through the up-down arrangement of the upper cold flow area, the hot flow area and the lower cold flow area.

Description

technical field [0001] The invention relates to the technical field of distillation devices, in particular to a high-efficiency membrane distillation component for desulfurization wastewater treatment. Background technique [0002] my country is a country dominated by thermal power generation. Coal-fired power generation is still the main way of power generation in our country. The resulting pollution has brought about very serious environmental problems. Therefore, we must try to reduce pollution. Wastewater from power plants has been desulfurized to remove sulfur, but its chemical composition is still very complex and difficult to treat. The common methods are multi-stage flash evaporation, membrane separation method and so on. For methods such as multi-stage flash evaporation, there are defects such as high energy consumption and expensive equipment, while the driving force of the membrane separation method is generally the concentration difference, pressure difference, ...
