Description

The storage tank oil-water automatic segregator

Technical field: the utility model relates to a kind of oil water separator, particularly a kind of storage tank oil-water automatic segregator belongs to the petrochemical industry mechanical field.

Background technology: the storage tank quantity of petroleum crude oil, oil product and chemical that China is present has more than 100,000 nearly, and a large amount of oil products or chemical products store wherein, comprise oil liquefied gas or the like.These products are stored in storage tank certain the time, tank bottom all can produce precipitation water or crystal water to some extent, for guaranteeing the quality of product, people must drain the unnecessary ponding that exceeds standard by the draining bottom valve under the storage tank, and domestic this drainage works is all finished by the manual mode of operation at present, in drainage procedure, need the workman to possess abundant drainage works experience, judging whether ponding in the storage tank has been discharged to requires the position, and to see by experienced drainer human, hear, the primitive method of touching is gone to judge and is had or not the oil product situation that leaks outside in the water, artificial method must be subjected to experience and round the clock light change and influence is observed and judge, so just exist artificial error objectively, if cause excessive discharging accidentally, oil product or chemical products are leaked, cause the environmental pollution and the safety hazard in storage tank zone, the loss that brings is huge.Find by literature search: the TSF-100 type automatic dehydration device (patent No. ZL97214865.5) of Honghu City, Hubei Province flood connection petrochemical equipment factory, but in use, oil-water separation is not satisfactory during draining, and action is not obvious when driving valve and closing valve, when closing valve water clock phenomenon is not to the utmost arranged, be difficult to assurance equipment all the year round for days autostable work reliably.

Summary of the invention: the utility model provides a kind of round-the-clock, automatic safety discharging that precipitates water in petroleum oil product, chemical products storage tank at the deficiencies in the prior art, prevents the storage tank oil-water automatic segregator of potential safety hazard.The utility model mainly comprises housing, cap, water inlet, water outlet, the ball float stabilizer rod, ball float, the lever adaptor union, clump weight, internally piloted valve, steam heating coil, its connection mode is: water inlet is established in the hull outside top, the below sets out the mouth of a river, establish cap directly over the housing, cap is divided into a ball float stabilizer rod in the housing, establish ball float in the housing again, stable hole is established at the ball float center, the lower hammer end of ball float stabilizer rod is inserted in the stable hole, the lever adaptor union is established in the ball float bottom, and the lever adaptor union is divided into clump weight, another termination internally piloted valve in the lever adaptor union, the internally piloted valve outlet is connected with water outlet, is provided with steam heating coil in the inner walls.The lever adaptor union comprises: movable bolt and limit lever, and movable bolt is connected with the ball float bottom, and limit lever is connected with internally piloted valve.Water inlet outside coupling end is taken over filter, and water outlet outside coupling end connects hand control valve (HCV).Oil-water mixture in the storage tank, enter the water inlet of filter to the oil water separator upper end, in the inflow housing, pass through the static of certain hour, water sedimentation is in the disconnector bottom, oil product is suspended in the top of disconnector, ball float in the disconnector is along with precipitation water increases, water level rises, ball float begins to float, the limit lever that drives ball float bottom lever adaptor union rises, and rises to certain angle, and the oil separation control cock promptly can be opened moment automatically, the water outlet of precipitation water in the shell separator by the shell separator bottom emitted, precipitation water in the storage tank is again by the water inlet on top, replenish to enter in the shell separator, and the oil product that is suspended in layer waterborne is by coolant inlet pipe flow back into storage tank.When precipitation water discharged in the storage tank, oil product was followed and is entered in the disconnector, and precipitation is fallen under water in the disconnector, and ball float also descends thereupon, and depresses lever, and separate control valve resets at once, closes discharge port to stop draining, has finished the cyclic process of oil separation.

After this equipment was installed, the quantity discharged that storage tank is precipitated water can reach per hour 6-10 ton.When the discharging of the precipitation water in the storage tank stopped, disconnector inside remained a part of water that stays, promptly as water seal, and airtight control cock.In drainage procedure, the oleaginousness in institute's discharge water can be controlled in the 50mg/L index of regulation.This equipment can not only be applicable to clean cargo or the chemical products that density is less, can also be applicable on the storage tank of the various products that density is big, viscosity is higher.Such as, products such as crude oil, heavy oil.If in the winter time or extremely frigid zones use, the viscosity of oil product can uprise, disconnector inside is provided with the steam coil pipe of heating, the oil product that uprises with the viscosity in the steam heating disconnector, make its energy normal operation, consumes energy not during this cover storage tank oil-water automatic segregator work, the full automaticity running if add a small amount of watch-dog, can form the automatic monitoring system of storage tank district discharge water, and has an environment-friendly function, equipment is installed simple, and operation is saved worry, safety durable, easy to maintenance, the standing charges of product are low.
