Description
Technical Field
The utility model belongs to the technical field of tire cracking, relates to an oil-water separation process in tire cracking, and particularly relates to an oil-water separation device applied to a waste tire oil refining system.
Background
After the waste tires are recycled, the waste tires are generally decomposed into fuel oil, carbon black and steel wires by oil refining equipment, so that the resources are recycled. In the cracking process of the tire, the fuel oil generated by the reaction can be directly discharged out of the cracking reaction kettle in a gas state and is condensed into liquid fuel oil through a condenser; after the cracking of the tire is finished, carbon black generated by the reaction can be discharged out of the cracking reaction kettle through a slag discharging system. However, the raw materials of waste tires, rubber and the like used for oil refining contain certain moisture, and the moisture enters a condenser along with fuel oil in a gas state in the cracking process, so that the finally condensed liquid fuel oil often contains moisture, which seriously affects the oil quality.
In view of the above situation, it is common to select the liquid fuel oil cracked over a period of time to be collected and then subjected to oil-water separation. However, such an oil-water separation method often has the following problems: 1. the contact time of oil and water is long, so that the phenomenon of water-in-oil or oil-in-water is easy to occur, and the moisture is difficult to separate from the fuel oil; 2. the fuel oil components produced by the cracking in the period of time comprise heavy oil and light oil, wherein the density difference between the heavy oil and the water is not large, so that long-time precipitation is needed for separating water from the fuel oil.
Disclosure of Invention
In order to solve the defects in the prior art, the utility model aims to provide the oil-water separation device applied to the waste tire oil refining system, so as to achieve the purposes of reducing the difficulty of oil-water separation, shortening the time of oil-water separation and ensuring the quality of final oil products.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows: an oil-water separation device applied to a waste tire oil refining system comprises an oil-water separator connected to a pipeline between a condenser and an oil tank through a three-way valve, and an outlet at the bottom end of the oil-water separator is communicated with the oil tank through a communicating pipe provided with an oil discharge valve; the upper part of the communicating pipe oil drain valve is communicated with a drain pipe, and the drain pipe is provided with a drain valve.
As a limitation of the utility model, the top end of the oil-water separator is communicated with the oil tank through a pressure discharge pipe.
As another limitation of the utility model, a transparent window is arranged on the side wall of the oil-water separator along the height direction of the oil-water separator.
As a further limitation of the utility model, a glass tube sight glass is arranged above the part where the communication pipe is communicated with the drain pipe.
As still further limitation of the present invention, the communicating pipe is communicated with the bottom outlet of the oil-water separator through the compensator.
Due to the adoption of the technical scheme, compared with the prior art, the utility model has the following beneficial effects:
(1) the utility model adopts a pre-oil-water separation treatment mode before fuel oil enters the oil tank, avoids the phenomenon of 'water in oil' or 'oil in water' caused by overlong contact time between the condensed fuel oil and water, and reduces the difficulty of oil-water separation; in addition, the water vapor enters a condenser together with the light oil for condensation in the earlier stage of cracking the waste tires (when the reaction temperature is 90-130 ℃), and the heavy oil is not yet extracted, so that the situation that the heavy oil and the water are mixed is avoided, and the light oil and the water are precipitated and separated (the difference between the density of the light oil and the density of the water is larger) by utilizing the method. The oil-water separation device has high efficiency and is more thorough, and the oil quality is greatly ensured.
(2) The oil-water separator is connected to the pipeline between the condenser and the oil tank through the three-way valve, so that the oil-water separator can be selectively used. When the reaction temperature is raised to above 130 ℃, water vapor is not mixed in the fuel oil, and oil-water separation is not needed, so that the oil-water separator is stopped, the liquid fuel oil directly enters the oil tank, and the oil outlet efficiency of the equipment at this stage can be ensured.
(3) The top end of the oil-water separator is communicated with the oil tank through the pressure discharge pipe, and the pressure of the air in the oil-water separator (namely, non-condensable gas generated in the cracking process) can be released by means of a pressure discharge system of the oil tank, so that accidents caused by overlarge air pressure in the oil-water separator are avoided.
(4) The transparent window arranged on the side wall of the oil-water separator is convenient for workers to observe the internal oil-water separation condition so as to discharge the separated water in time or stop using the oil-water separator according to the condition.
(5) According to the utility model, the glass tube arranged on the communicating pipe is convenient for workers to observe the discharge conditions of condensed water and fuel oil in the oil-water separator according to the venomous insects, so that the drainage valve can be closed and the drainage valve can be opened at proper time, and the condition of fuel oil waste is avoided.
(6) The compensator arranged in the oil-gas separator is beneficial to the disassembly of a connecting structure between the oil-gas separator and the oil tank, and is convenient for the follow-up maintenance work.
