Description
The present invention relates to the automatic dehydration method and the equipment thereof of hydrocarbon ils.Or rather, relate to be applied to refine oil, the automatic dehydration method and apparatus of material in various fractionation return tank of top of the tower, intermediates jar and crude oil or the material storaging tank in the industry such as chemical industry, petrochemical complex, medicine, light industry.International Classification of Patents is C10G33/00.
In the prior art, the method that is used for aforesaid device material dewatering has two kinds: a kind of is manual draining, and another kind is that instrument automation dehydration Controlling System is installed.
By manual observation water-oil interface manual operations draining, this method not only results in hand cramps to the operative employee has increased labour intensity, and the dehydrating effect extreme difference.Instrument automation control dehydration, although can reach the dehydration purpose, but a cover Controlling System costs an arm and a leg, investment is up to 3～50,000 yuans, and because quality, the ageing equipment or malfunctioning of power failure and Controlling System components and parts, tend to cause immeasurable financial loss, even serious fire and human casualty accident can take place.
In order to solve return tank of top of the tower phegma band water, intermediates jar deposition dehydrating and petroleum tank dehydration problem, numerous technician attempts attempt always find the cheap automatic dehydration method and apparatus of a kind of equipment manufacturing cost easy and simple to handle, safe and reliable, but fail to realize always.
The purpose of this invention is to provide a kind of automatic dehydration method and apparatus.This method is easy and simple to handle reliable, and equipment manufacturing cost is low, and is highly sensitive, dehydrating effect good, and is applicable to the automatic dehydration of fractionation return tank of top of the tower, intermediates jar and the material storaging tank of various processing poweies.This method can replace existing manual draining and instrument control dewatering.
The object of the present invention is achieved like this:
A kind of automatic dehydration device, this water trap is by tank body (1), floating drum (2), dehydration valve (3), connecting rod (4), liquid inlet (5), liquid exit (6), water port (7), hand-hole (10), sewage draining exit (11), liquidometer mouth (8), pressure warning unit ozzle (9) and lever support (12) are formed, its special sheet is that the valve rod (39) of floating drum (2) and dehydration valve (3) is connected to the two ends of connecting rod (4), connecting rod (4) is supported by lever support (12), floating drum (2) is positioned at the water-oil interface place of tank body (1), floating drum (2) fluctuates with the rising or the decline of water-oil interface, and the leverage by lever (4) opens or closes dehydration and reads (3).Floating drum (2) is made up of cylindrical shell (20), the double-deck end socket (21) of cylindrical shell, center counterweight pipe (23), center counterweight channel closure (22), cylindrical shell backing plate (24), bolt tip hole (25) and float strut (26), and the shape of floating drum (2) is long garden tubular.In the described center counterweight pipe (23) balance weight iron is housed.Connecting rod (4) is made up of two risers (27), top board (28), bearing (30) and bearing connection board (29).Dehydration valve (3) is made up of adapter sleeve (35), valve rod (39), water inlet lid (34), water inlet hole, garden (36), valve seat (33), adapter (40), spherical valve head (38) and bolt hole (37).Described water inlet lid (34) profile is positive hexagon, and 6 water inlet holes, garden (36) are arranged on it.Lever support (12) is made of a riser.The automatic dehydration device is used for the automatic dehydration of the material in fractionation return tank of top of the tower, intermediates jar and crude oil or the material storaging tank.
Automatic dehydration device working process of the present invention is as follows.As shown in Figure 1, the automatic dehydration device is installed in the bottom of return tank of top of the tower, intermediates jar or material storaging tank, return tank of top of the tower, the water that settles down in intermediates jar or the material storaging tank is carried an oil product secretly and is entered in the tank body (1) by automatic dehydration device liquid inlet (5), because the proportion of water greater than the proportion with oil product under the condition, leans on the effect of gravitational difference to make water and oil product further settlement separate in the automatic dehydration device.The interface of oil product and water always remains on the middle part of water trap tank body.When more water enters water trap, to rise in interface in jar, floating drum (2) also increases, open dehydration valve by the leverage of connecting rod (4) and make spherical valve head (38) lift off a seat (33), water enters dehydration valve by 6 prosopyles on the water cover (34), and the slit that produces when leaving by spherical valve head (38) and valve seat (33) is discharged the water port (7) that dehydration valve enters the automatic dehydration device and drained into outside the jar then.Because jar interior water is discharged, water-oil interface descend thereupon in the water trap, after the interface drops to the tank body intermediate altitude, because of floating drum (2) descends dehydration valve are closed gradually till Close All, and the interior water-oil interface of water trap tank body this moment keep intermediate altitude.The oil product of being brought into water trap by water is returned in the oil product return tank (intermediates jar or material storaging tank) by liquid exit (6) automatically by the impellent of difference in specific gravity behind deposition dehydrating.
The present invention has following advantage with the prior art ratio: 1. simple in structure, cost is low, maintenance is installed conveniently.2. have the secondary oil water separation function, the water oleaginousness of being discharged is well below the emission standard of device or basin permission.3. highly sensitive, the reliability height has avoided human casualty accidents such as oil leak accident that instrument fault or power outage cause and fire to take place.4. good sealing property is arranged, and certain buffering capacity is arranged.When water trap is out of order, can report to the police, make operator in time find repairing in time by the interface.5. working pressure is changed in from normal pressure to the 2.5MPa scope stronger adaptability is arranged.6. this automatic dehydration device is adapted to the automatic dehydration of return tank of top of the tower, intermediates jar and the material storaging tank of product such as liquefied petroleum gas (LPG), gasoline, diesel oil, kerosene in refinery, chemical plant, the petroleum chemical plant and crude oil oil products such as (stock oils), can replace the instrument automation at the positions such as return tank of top of the tower of existing various separation columns to control dewatering system, replace the dehydration control device of various intermediates jars and crude oil basin (stock oil basin).
