technical field

The invention relates to the technical field of oil-water separation, in particular to a continuous oil-water separation device.

Background technique

In the existing oil-water separation equipment in the methanol-to-oil system, based on the fact that oil is insoluble in water and has a density lower than water, there have been many oil-water separation methods using static separation by taking advantage of its properties of being insoluble in water and having a density lower than water. However, the separation effect and separation efficiency still need to be improved and improved. In order to accelerate the separation of oil and water, the method of forced centrifugation is generally adopted, that is, the oil-water mixture is centrifuged by increasing external power, which undoubtedly increases energy consumption; or the dynamic component of the rotor is used, which is prone to failure.

China Patent No. 201620123836.5 is a gas, water, and oil separation device, including a gas-liquid separation area, an oil-water separation area, an oil product collection tank and a waste water collection tank. The gas-liquid phase mixture of the condenser enters the gas-liquid separation zone of the separation device through the pipeline and the inlet, and a separation plate is set between the gas-liquid separation zone and the oil-water separation zone. There is a gap on the downward sloping side. The upper layer of the oil-water separation area is the oil storage area, and the lower layer is the water storage area. The oil storage area and the water storage area automatically form an oil-water interface; Oil product collection tank and waste water collection tank. The oil product collection tank is composed of overflow weir, bottom plate and oil-water baffle to form a semi-enclosed area. In addition, the top of the oil-water baffle is fixed to the inclined-plane isolation plate, and the bottom of the oil product collection tank is equipped with pipelines and storage tanks. Connection; waste water overflow weir or waste water overflow pipe is set at the entrance of the waste water collection tank, and the bottom end is set with an outlet. By adopting multiple partitions and balancing pressure, the oil-water mixture is separated based on the principle of standing, although certain effects can be achieved, but the separation efficiency is difficult to guarantee.

China Patent No. 201310010162.9 is an oil-water separator, which includes a water inlet area, a separation area, an oil collection area and a water outlet area; the water inlet area is provided with a water inlet distribution pipe; The baffle plate is isolated from the overflow weir; the arc-shaped top of the baffle is connected to the upper half of the tank body, and a semicircular through hole is provided at the center of the top of the baffle; the arc-shaped bottom of the overflow weir is connected to the tank body The lower half of the body, the center of the bottom of the overflow weir is provided with a semicircular through hole; the separation area is provided with a nitrogen stirring tube; the separation area is isolated from the oil collection area by an oil outlet weir; the collection area The oil area and the water outlet area are separated by an oil baffle and a water outlet weir; the arc-shaped top of the oil baffle is connected to the upper half of the tank body; the arc-shaped bottom of the water outlet weir is connected to the lower half of the tank body, and the water outlet weir A semicircular through hole is provided at the center of the bottom; a first horizontal pipe is provided at the end of the water inlet distribution pipe; distribution holes are uniformly arranged at the bottom of the first horizontal pipe; The oil plate constitutes the oil gathering area; the oil outlet weir is L-shaped. The oily sewage flows into the water inlet area from the water inlet distribution pipe, and flows into the separation area through the baffle plate and overflow weir. The oil plate enters the water outlet area through the top of the outlet weir, and finally realizes the separation of water and light oil. This invention also adopts the principle of standing still to realize oil-water separation, and the efficiency cannot be guaranteed.

The Chinese patent number is 201210002763.0, a centrifugal oil-water separator, including a tray, a stem, an outer cylinder, a casing, and a rotor that can rotate relative to the stem in the outer cylinder. The tray, stem and outer cylinder are integrated, and the rotor is sleeved on the on the core column and placed between the core column and the outer cylinder; the casing is covered on the outside of the outer cylinder and fixed on the tray by bolts to form a closed inner cavity; the rotor is formed by the cylinder and protrudes from the bottom of the cylinder. It is composed of a column filter, the bottom of the rotor cylinder is provided with a nozzle, and the inner cavity of the column filter communicates with the inner cavity of the outer cylinder through the nozzle; the core column is provided with an inlet, and the tray is provided with a water outlet , There is an oil outlet on the cover; a heater is installed at the inlet, and filter screens are respectively installed on the middle part of the stem and the outer cylinder. The oil and water are effectively separated by a completely mechanical method without adding any chemicals. The structure is simple, the operation is convenient, and the discharge is reduced; the high-pressure oil-water mixture hits the outer cylinder to generate a reaction force, which makes the rotor rotate at a high speed, so that the small droplets of the oil-water mixture are fully separated. Crushed, so that the oil-water mixture changes from emulsified to suspended, and then under the action of gravity, the oil and water will precipitate and separate by themselves. The whole device does not require any power input, saving energy and reducing emissions. This scheme uses the pressure of the high-pressure oil-water mixture itself as power, which has the effect of saving energy. When the high-pressure oil-water mixture enters the rotor, it drives the rotor to rotate and passes through the column filter before being injected through the nozzle. The pressure of the high-pressure oil-water mixture is part of the transmission. Consumed in the rotating power of the rotor, part of it is consumed through the column filter. In the absence of an external power source, the pressure of the high-pressure oil-water mixture is consumed and wasted many times, making the oil-water separation effect poor and unable to achieve high Good separation effect, at the same time, the oil-water mixture does not have a special flow channel, and various invalid impacts directly entering the rotor area will also consume a lot of energy, thus affecting the effect of oil-water separation.
