Among the figure: 1, liquid header, 2, bracing frame, 3, board-like coalescent pack, 4, catch the foam silk screen, 5, press grid, 6, the pipe distributor of band shower nozzle.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of mist catching separation device of the present invention comprises pressure grid 5, catches foam silk screen 4, board-like coalescent pack 3 and bracing frame 2.Constitute jointly and catch the foam separating component by catching foam silk screen 4 and board-like coalescent pack 3, catch foam separating component below and be provided with bracing frame 2, the top is provided with presses grid 5, catches the foam separating component and is pressed together on bracing frame 2 and presses between the grid 5, and each member piecemeal is made, and piecemeal is installed.
For easy crystallization, stick or easily to catching the produce electrolysis system of corrosion of foam separating component, reply is caught the foam separating component and regularly carried out hydro-peening.So the present invention is provided with the pipe distributor 6 of being with shower nozzle above catching the foam separating component, clean once at set intervals.Catch the below of foam separating component and be furnished with liquid header 1, to collect all liq that flows down above, exclusive processing has again improved the distribution situation of gas in tower body or container, prevents bias current.Liquid header 1 adopts the venetian blind type structure, and there is very big hole sectional area the upper end, is convenient to gas and passes through.According to the difference of system, liquid header 1 can be arranged on the reducer of tower body or container, the higher gas of flow velocity is had the effect that distributes again again.Because liquid header 1 can be regained whole liquid, evaporation of liquid amount in the not increase system is very little to the influence of process condition, is convenient to control.
