Abstract
The utility model discloses an emergency water drainage device of a floating roof oil tank, which is characterized by comprises a filtering water collecting cover, a sealing system, a floater, a water drainage tube and a water-sealing tank. One end of the sealing system is provided with the filtering water collecting cover, and the other end of the sealing system is arranged in the water-sealing tank. The floater is placed in the sealing system, the water-sealing tank is provided with an opening and connected with the water drainage tube, when the height of accumulated water is higher than the filtering water collecting cover, the accumulated water can be filled in the sealing system, the floater can be rushed down by impact force of the accumulated water, and the accumulated water passes through the water-sealing tank to be drained through the water drainage tube. The emergency water drainage device can drain overloaded accumulated water and can prevent storage liquid from spilling backwards when entering an emergency water draining state, simultaneously has the functions of reducing damage of water for sealing and collecting rainfall and is convenient for operating and managing.
Description
Technical field
The utility model relates to and is used for petrochemical complex, the drainage system and the device in fields such as storage transportation, the urgent freeing arrangement of particularly a kind of floater.
Background technology
The tank deck of external floating roof tank directly is exposed to atmosphere, and the ponding and the foreign material that collect on the floating top will influence the floating safe in operation that pushes up, and all central drainage system can be housed for this reason.Current external floating roof tank central authorities drainage system roughly is divided into two types, one type be the rigid drainage system another kind of be the flexible water drainage system.Generally speaking, rainwater is by outside the central drain drain tank.But when central drain hose stops up or leakage of oil can't use the time, the ponding row on the floating top does not go out; In addition, when raining in torrents, because moisture conditions is bigger, the central drain drainage ability is limited, can't in time discharge ponding.Above situation will cause drainage effect not good.
The utility model content
The utility model provides a kind of floating roof tank urgent freeing arrangement, is used for the floater draining.
The urgent freeing arrangement of a kind of floater comprises the filtration catchment covers, sealing system, float, drain hose and water sealed tank; Said sealing system one end is installed said filtration catchment covers, and the other end places said water sealed tank; Said float places said sealing system, and said water sealed tank has opening and connects said drain hose; After ponding surpass to filter catchment covers, water just injected in the sealing system, utilized the impulsive force of water that float is dashed and turned over, and ponding is discharged by said drain hose through said water sealed tank.
Wherein said float is the corrosion-resistant steel hollow spheres.
The urgent freeing arrangement of the floater of the utility model, when ponding surpasses floating bearing responsibility when carrying design, overload ponding flows in the urgent freeing arrangement drain hose through filter screen; Utilize the impulsive force of water; With the float upset, device gets into urgent hull-borne can get rid of overload ponding, can prevent that again liquid storage from falling to overflow; Also have simultaneously and reduce water seal moisture loss and the function of collecting precipitation, the handled easily management.
Description of drawings
Fig. 1 is the urgent freeing arrangement structural representation of floater.
The specific embodiment
In order better to understand the technology contents of the utility model, special act specific embodiment and conjunction with figs. are introduced technical scheme.
Consult Fig. 1, the urgent freeing arrangement split of floater structural representation.The urgent freeing arrangement of floater, said freeing arrangement comprise filtration catchment covers 1, sealing system 2, float 3, drain hose 4 and water sealed tank 5; Said sealing system 2 one ends are installed said filtration catchment covers 1, and the other end places said water sealed tank 5; Said float 3 places said sealing system 2, and said water sealed tank 5 has opening and connects said drain hose 4; After ponding surpass to filter catchment covers 1, water just injected in the sealing system 2, utilized the impulsive force of water that float 3 is dashed and turned over, and ponding is discharged by said drain hose 4 through said water sealed tank 5.
This drain hose 4 designed displacements are 40-50m
3/ h.Float 3 is an oCr18Ni9 corrosion-resistant steel hollow spheres.When the anhydrous discharge in floating top, float 3 is horizontal floating condition in drain hose 4, the water sealing liquid cover is lived, and prevents water evaporates.Because this device has adopted natural rainfall to collect measure, thereby under the normal operation, can in drain hose 4, regularly add water again.When ponding surpass to filter catchment covers 1 in the application, water just injected in the emergency draining 4, utilized the impulsive force of water that float 3 is dashed and turned over, and device gets into hull-borne.
The utility model gives the installation method of the urgent freeing arrangement of above-mentioned floater.Double plate floater capping.Single deck floating roof tank, big volume oil tank or moisture conditions larger area capping, otherwise take off limit.Fitness for purpose is following, and the floating top seal groove lower edge of single-deck should be apart from liquid level 250mm in the oil tank.Upper surface to the height that filters the catchment covers lower edge is generally 120mm from floating top on double plate floating top.Any accessible position on the top can floated in the installation site.
During installation, water sealed tank is disassembled, sent in the jar by manhole, drain hose is inserted to install by the pontoon top and shelves, and welding assembly together then.Design should be according to local maximum rainfall, situation about stopping up fully at the central drain load-carrying capacity on top of floating downward.
Claims (5)
1. the urgent freeing arrangement of floater is characterized in that, this device comprises filtration catchment covers, sealing system, float, drain hose and water sealed tank; Said sealing system one end is installed said filtration catchment covers, and the other end places said water sealed tank; Said float places said sealing system, and said water sealed tank has opening and connects said drain hose; After ponding surpass to filter catchment covers, water just injected in the sealing system, utilized the impulsive force of water that float is dashed and turned over, and ponding is discharged by said drain hose through said water sealed tank.
2. the urgent freeing arrangement of floater according to claim 1 is characterized in that said float is the corrosion-resistant steel hollow spheres.
3. the urgent freeing arrangement of floater according to claim 1 is characterized in that, if said floater is a single deck floating roof tank, the floating top seal groove lower edge of single-deck then is set should be apart from liquid level 250mm in the oil tank.
4. the urgent freeing arrangement of floater according to claim 1 is characterized in that, if said floater is the double plate floater, then the floating top of double plate is 120mm from floating top upper surface to the height that filters the catchment covers lower edge.
5. the urgent freeing arrangement of floater according to claim 1 is characterized in that said sealing system does not have ponding when said freeing arrangement is not worked, and float is horizontal floating condition in the sealing system pipe, and the water sealing liquid cover is lived to prevent that water from dividing evaporation.
