Abstract
The utility model discloses a radiation type multiple-hole tubular dewatering device for a storage tank. The bottom inside a storage tank is provided with a plurality of multiple-hole suction tubes which are arranged radially. The centers of the radiation type suction tubes are provided with a collecting tank which can induce water to merge, a delivery tube which is connected to the collecting tank is extended out of the storage tank, and a valve is arranged on the delivery tube. The utility model has the characteristics of simple and rapid operation, good energy saving, high safe reliability and low oil product carrying in dewatering. The utility model breaks through the dewatering theory of a disc type dewatering device in the storage tank, so that an entire oil-water interface can be always kept horizontal in the process of dewatering, so that the gyroidal free vortex can not happen, and the problem of the dewatering with oil can be avoided. An emptying valve can be completely opened for dewatering at high speed, so that the operation time of the dewatering can be greatly shortened. All the components of the utility model are arranged in the oil storage tank, so that excessive heat insulating traced materials are not required, and the energy consumption can be saved.
Description
(1) technical field
The utility model belongs to petrochemical complex storaging and transport technology field, is specifically related to a kind of storage tank oil dehydrating plant.
(2) background technology
At present, the accumulating field is attached great importance to safety and reliability in the dewatering operation course of all kinds of petrol storage tanks bottom.The disc type moisture trap is to press close to the bottom to be provided with one and to be used for water absorbing circular magnetic chuck in storage tank in the early stage storage tank, by conduit and valve water is discharged to outside the jar.The principle of work of this kind moisture trap is: when opening valve and carry out dehydrating operations, the water of petrol storage tank bottom is sucked in the conduit by the periphery of suction disk under the static pressure effect, and through outside the valve drain tank.But this moisture trap is in carrying out dehydrating operations, when the aperture of valve is big, the petrol storage tank inherence is that the center can produce a kind of helix free vortex phenomenon that is called as with the suction disk, this moment, water rotated around disk with very high rotative speed, cause the oil-water boundary to reduce rapidly, oil product is sucked into produces dewatering bands oil problem in the conduit in disk perimeter.Usually for fear of this phenomenon, have only that little so each operation dehydrating amount is very little to a certain degree just not being with oil with valve opening, dewatering time reaches a few hours, is unfavorable for dehydrating operations.
(3) summary of the invention
The purpose of this utility model provides a kind of storage tank radiation porous tubular type moisture trap, fundamentally to solve the deficiency of disk moisture trap, make storage tank more safe and reliable in fast dewatering operation, significantly reduce draining and carry oil product.The technical solution adopted in the utility model is: storage tank radiation porous tubular type moisture trap is at the storage tank inner bottom part a plurality of porous water-absorbing pipes to be set, and make these sucking tubies be radiation to arrange, the sucking tube center of arranging at these radiations is provided with the collecting box that water is converged, be connected on the collecting box and lead to the outer delivery line of storage tank, valve is housed on the delivery line.
When carrying out dehydrating operations, because the suction hole of porous water-absorbing pipe disperses, and these sucking tubies are radiation again and arrange, and can prevent the generation of helix free vortex so effectively.
The utility model is simple to operate, dewatering speed is fast, and good energy saving property has safe reliability height and dehydration and carries the few characteristics of oil product.It has broken through the dewatering Principle of disc type moisture trap in the storage tank, makes that in the dewatering operation course whole oil-water interface remain level, can not produce the helix free vortex, has stopped dewatering bands oil problem.Water discharging valve can be opened fully and carry out fast dewatering, has shortened the dehydrating operations time greatly.All parts of the present utility model all are arranged in the petrol storage tank, do not need too much insulation companion hot material is set, so can save energy consumption.

(5) specific embodiment
Storage tank radiation porous tubular type moisture trap is that pot bottom is provided with a plurality of porous water-absorbing pipes 5 in storage tank 1, and make these sucking tubies be radiation to arrange, be provided with the collecting box 6 that water is converged at the sucking tube center that these radiations are arranged, be connected to delivery line 7 on the collecting box, valve 4 is housed on the delivery line.Outer tube, top that sucking tube 5 has a suction round by the bottom have the interior pipe of round and end-plate etc. and form, this structure helps outer tube along whole length suction evenly, and become radiation shape to be welded on the collecting box 6, can prevent the generation of helix free vortex so effectively.Collecting box 6 by the tube sidewall have the outer sleeve that is used to connect sucking tube 5 inner orifices, inner core and up and down flat shrouding etc. form, this structure helps from the water yield of pipe in each sucking tube 5 even, all shut with flat shrouding the outer sleeve upper and lower end face of collecting box 6, its inner core upper surface and last flat shrouding weld, certain slit is stayed with following flat shrouding in the lower end, so that water flows, the outer sleeve side-wall hole connects the interior pipe of sucking tube 5.One of delivery line 7 terminates in the inner core sidewall of collecting box 6, and the other end is received on the exterior valve 4 of petrol storage tank.Caging bolt group 8 is made up of screw bolt and nut and bottom pad plate, and 1 welding of its bottom pad plate and storage tank is lived, and its upper nut can limit the termination of sucking tube 5 and upwards lift, and the hole is drawn onto oil product to prevent to absorb water.Adjustable bolt group 9 also is made up of bolt, nut, otic placode and backing plate etc., its welding with backing is on storage tank 1, otic placode is welded in the outer sleeve side of collecting box 6, and totally three adjustable bolt groups 9 are used for support set mould assembling 6, regulates the levelness of collecting box 6 by screw bolt and nut.Synchronous oil-water interface monitor 10 structures that are installed on the tank wall are seen Fig. 5, part 10-1 is used for fixing and the leak free seal receptacle, part 10-2 is the synchronous suction pipe that is used to observe oil-water interface, part 10-3 is used for the hollow rotating shaft that rotation is synchronously derived, part 10-4 is the synchronous handle that is used to rotate, and part 10-5 is used to observe the vent valves of oil-water interface.
