Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in accompanying drawing 2,3: the utility model is a kind of for the liquid distribution trough in concentration tower 1, this liquid distribution trough comprises tower tray 9, tower tray 9 is provided with several air discharge ducts 8 passing perpendicularly through tower tray 9, air discharge duct 8 is connected on tower tray 9 by pin 10, the outage 11 through tower tray 9 is attached with in the side of air discharge duct 8, air discharge duct 8 is provided with the top cover 6 of exhaust outlet, and several top covers 7 to be connected on air discharge duct 8 by winning in succession, and keep suitable distance with the exhaust outlet of air discharge duct 8.
The preferred embodiment of the utility model is that described tower tray 9 one-tenth is discoid, and described air discharge duct 8 is evenly distributed on tower tray 9 with the some rows of outage 11 one-tenth.
The utility model further preferred embodiment is, the upper end of described outage 11 is positioned at above the square position of tower tray 9, and the upper end of several outages 11 outwards surrounds cone-shaped setting by the center of tower tray 9.
The utility model further preferred embodiment also has, and is provided with annular retaining ring 12 at the adjacent edges of described tower tray 9 upper surface.
The utility model further preferred embodiment also has, and described liquid distribution trough 4 polytetrafluoroethylene (PTFE) synthetic material processes.
As shown in Figure 1, the preferred embodiment of the utility model also has, and matches below described liquid distribution trough 4 with the filler 2 of the ceramic corrugated plating be arranged in concentration tower 1, matching with the overflowing board 5 be arranged in concentration tower 1 above of described liquid distribution trough 4.
The utility model further preferred embodiment also has, and includes filler 2 district, redistributor 3, liquid distribution trough 4 and overflowing board 5 from bottom to top successively in described concentration tower 1.
First the utility model adopts ceramic corrugated plate packing to substitute original ceramic saddle/rings filler in bulk 2.The filler 2 of pottery corrugated plating has the advantages such as geometry is reasonable, specific area is large, voidage is large, resistance is little, operating flexibility is large, anti-blocking is strong compared with original filler.It has higher mass-and heat-transfer efficiency, can improve the production load of tower after using, and realizes energy-conservation, reduction steam consumption.
After adopting the filler 2 of ceramic corrugated plating, original liquid distributor 4 does not match with new filler 2, therefore another important measures of the present utility model have also done new design to original shower nozzle liquid distribution trough, substitute original liquid distribution trough with the liquid distribution trough 4 of an even distribution type, make it to match with new filler.
Even distribution type liquid distribution trough 4 described in the utility model processes with polytetrafluoroethylene (PTFE) synthetic material.Its structure is provided with several air discharge duct 8 on a tower tray 9, and be provided with outage 11 in the outside of air discharge duct 8, air discharge duct 8 is fixed on tower tray 9 by pin 10.Above per pass air discharge duct 8, all fill a boat-shaped top cover 6, described boat-shaped top cover 6 is won in succession by several and 7 to be fixed on above the exhaust outlet of air discharge duct 8, and keeps certain distance with the exhaust outlet of air discharge duct, so just forms a complete liquid distribution trough 4.
Such liquid (dilute sulfuric acid) is sprayed onto on boat-shaped top cover 6 through overflowing board 5, then overflows to tower tray 9 from top cover 6, and tower tray 9 forms corresponding liquid level, and is divided equably by the outage 11 outside air discharge duct 8 and be sprinkled upon on packing layer.Outage 11 outside air discharge duct 8, arrange in multilayer, the liquid level on tower tray 9 is higher, and liquid then flows to packing layer by more outage 11, and the liquid spilt to packing layer through outage 11 is more.Such liquid distribution trough 4 just can according to the abundance of the automatic regulates liquid of the load of tower.And under the load condition of various tower, all can reach the uniform distribution of liquid.Gas in tower is then risen by air discharge duct 8.
By above improvement, replace original filler to increase contact area with regular corrugated plate packing, improve the mass transfer in tower, heat-transfer effect.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
