Abstract

The utility model relates to an oil-water separator, which can automatically discharge the water in an oil storage tank out of the oil storage tank. The oil-water separator is also suitable for an automatic dewatering device for an oil tank to separate the water from the liquid whose specific gravity is different from the water and can not dissolve with the water. The oil tank is connected with a sewage slot through a water outlet pipe provided with a valve. A dewatering tank connected with the oil tank through a water inlet pipe provided with a valve and an automatic actuating mechanism composed of a secondary instrument connected with the dewatering tank through a sensor and a cable and a control valve are also arranged. The dewatering tank is added, and the water in the oil tank can settle down to the dewatering tank. The dewatering of the oil tank is sufficient, the oil content in the discharged water is low, and the pollution is reduced. The utility model can automatically dewater and reduce the labor intensity. The dewatering process is stable and reliable. The utility model can also eliminate oil leak accidents.

Description

Oil tank automatic dehydration device
The utility model relates to a kind of oil water separator that the automatic drain tank of moisture content in the petrol storage tank is outer, also be applicable to different with the proportion of water and with the immiscible liquid of water with the oil tank automatic dehydration device that separates between the water.
In oil refining, the chemical industry numerous wet tanks is arranged, often contain the moisture content of some in these liquid, the quality of the product that dispatches from the factory is produced or is reduced in influence.For outside the water drain tank in the petrol storage tank, common method is to open a dewatering outlet at pot bottom, and connect valve, water during valve opening in the jar just flows out, rapidly with valve closing, need artificial long-time supervision water outlet in case run oil when the dewatering outlet begins effluent oil, labour intensity is big, take more oil out of toward the contact meeting, not only wasted but also contaminated environment.
At present the buoyancy difference of utilizing between profit is arranged also, carry out automatic dehydration with mechanical means, but this mechanical easy break-down.
The purpose of this utility model is to provide a kind of and can reduces labor intensity, easy to use, oil tank automatic dehydration device that result of use is good.
The utility model is achieved in that oil tank automatic dehydration device is linked into an integrated entity oil tank and sump by the coolant outlet pipe of band valve, comprises that also coolant inlet pipe and the oil tank bonded assembly water knockout by the band valve reaches the automatic executing agency that passes through sensor, cable and water knockout bonded assembly secondary instrument and constitute with coolant outlet pipe, secondary instrument, sump bonded assembly control cock.
Fig. 1. structural representation of the present utility model.
Fig. 2. the water knockout structural representation.
Fig. 3. the secondary instrument electrical schematic diagram.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Water knockout (6) is a floor space≤oil tank (a 1) floor space 1/10, and highly is 0.4~2 meter container.It is other to be installed in oil tank (1), and tank deck is lower than or approaches oil tank (1) jar end.The top is equipped with oil return pipe (3), coolant inlet pipe (5), coolant outlet pipe (10), be connected with oil tank (1), sump (14) by valve (2), (4), (13) respectively, coolant inlet pipe (5) stretches in the water knockout (6), and coolant outlet pipe (10) stretches at the bottom of jar only 20~500mm place.The profit state sensor of WB-ITB microwave type is installed, upper and lower, protection sensor (9), (8), (7), also optional profit state sensor on the sidewall with types such as condenser, conductance types.
Control cock is valve (13), is motorized valve ZAZT-10-50, also can be pneumatic valve, electromagnetic valve, is connected with coolant outlet pipe (10), sump (14), secondary instrument (12) respectively.
Protection sensor (7) is located near being positioned at coolant outlet pipe (10) opening on the upper side.
In the secondary instrument (12), the upper and lower biography of V, upper and lower base are respectively the signal value and the baseline signal value of upper and lower sensor (9), (8), and V protects and pass, protects signal value and baseline signal value that base is respectively protection sensor (7).
Each sensor has 3 connection terminals, is respectively 12 volts, 0 volt and output line, and 12 volts of terminals in 3 sensors are all received F, all receive G for 0 volt, and output line meets A, B, C respectively.Output signal is 1 volt in the oil, and output signal is 5 volts in the water, and the big I of reference signal is regulated by three potential devices, is transferred to 2.5~3.5 volts.Be connected in series J on the current supply circuit of valve (13) 2(connection terminal is D, E).
After oil tank (1) has deposited one deck water, Open valve (2), (4), valve (13) is closed condition.Water in oil tank this moment (1) flows to water knockout (6) through coolant inlet pipe (5), because water knockout (6) is more much smaller than oil tank (1), take out and to become thicker water layer after jar (1) thin water layer flows into water knockout (6), and the oil reservoir on it flows back to oil tank fast by oil return pipe (3), thereby water can flow into water knockout (6) fast by coolant inlet pipe (5).Rising along with oil-water interface in the jar, when upper sensor (9) when running into water, three sensors all measure water, upper and lower, protect sensor (9), (8), (7) signal and be 5V, A, the B, the C that are transferred to secondary instrument (12) through cable (11) hold, and compare comparator output high level signal respectively with their a reference value, these three high level signals after logic gates is judged, two aerotron T 1, T 2Conducting, relay J adhesive, J 1, J 2Conducting is opened valve (13) energising, begins dehydration, and at this moment coolant outlet pipe (10) just drains into sump (14) from water knockout (6) sucking-off water.
Through a period of time, oil-water interface descend.When upper sensor (9) runs into oil, export 1 vor signal, down, protect sensor (8), (7) and run into water and export 5 vor signals and deliver to A, B, the C of secondary instrument (12), at this moment make T through cable (11) 1End T 2Conducting is because J 1Conducting, so J continues adhesive, valve (13) keeps energising, continues to open dehydration.
When upper and lower sensor (9), (8) when all running into oil, export 1 volt signal, and the protection sensor runs into water and exports 5 vor signals.After comparator and logic gates judgement, make T 1, T 2All end, relay J disconnects, J 1, J 2Open, stop valve (13) power supply, then valve (13) is closed, and stops dehydration.
When unforeseen circumstances occurring, make protection sensor (7) meet oil and when exporting 1 volt oily signal, at this moment comparator output low level thereafter makes buzzer phone B 1Pipe light-emitting diode L 1Luminous, and make T 2End hard closing valve (13).
The utility model is compared with prior art: because having increased drain sump, depositing in water in the oil tank is dropped to take off In the water pot, increase primary dewatering again, make oilcan dehydration abundant, dehydration is easy to control, in the water of discharge Oil content is low, saves crude oil, reduces and pollutes, alleviates labor strength.
Oil return pipe is installed on the drain sump, makes the water in the oil tank quick and stable flow into drain sump. Cause exists Automatic executing agency has been installed on the drain sump can have been reached the purpose of automatic dehydration. Adopt again upper and lower sensing The device structure, dehydration is reliable and stable, and has warning function just can stop oil leak accident, can also install Liquid level gauge and thermometer, easy to use, result of use good.
