Description

Technical Field

[0001] The utility model relates to the technical field of the application of a cyclone oil catcher, in particular to a cyclone oil catcher. Background Art

[0002] In the process of the oil refining process of the low-temperature carbonization technology, in order to wash and cool the dust particles in the flue gas, purify the coal gas, and at the same time increase the yield of shale oil collected from the flue gas, in the original design, a cyclone oil catcher is added behind the Venturi tube tower to further improve the process. However, there is still a situation of dust and mud accumulation in the sealed container. When the dust and mud adhered to the wall of the device reaches a certain degree, and because the diameter of the air outlet at the lower end of the cyclone oil catcher is small, it is very easy to cause the dust and mud and the air flow to be unable to be centrifugally separated, and then a vicious cycle of gas and liquid occurs, resulting in unstable internal pressure of the cyclone oil catcher and difficult to dredge. Content of the Utility Model

[0003] The utility model provides a cyclone oil catcher to solve the problems existing in the above background.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A cyclone oil catcher includes a cyclone oil catcher arranged inside a cross brace. A flushing pipe is connected in a through manner between the top of the cyclone oil catcher and a hot ring water pipe. One end of the flushing pipe extending into the inside of the cyclone oil catcher is connected with a spray head. The bottom of the cyclone oil catcher is connected with a tee joint, and a blind plate is further arranged at the bottom of the tee joint.

[0006] Further, a plurality of vertical rods are connected to the bottom of the cross brace, and reinforcing rods are arranged between the vertical rods.

[0007] Further, a gas inlet for coal gas is arranged at the top of the cyclone oil catcher, and an air outlet is arranged at the side of the cyclone oil catcher.

[0008] Further, a rotating shaft is arranged at one end of the gas inlet for coal gas extending into the inside of the cyclone oil catcher, and the rotating shaft is connected with a spiral blade.

[0009] Further, an overflow pipe is connected to the bottom of the cyclone oil catcher, and the tee joint is communicated with the overflow pipe.

[0010] Further, a gate valve is further arranged on the flushing pipe.

[0011] The utility model has the following beneficial effects:

[0012] A cyclone oil catcher provided by the utility model realizes rapid flushing of the inner wall of the device by adding a flushing pipeline at the hot loop water pipe and installing a spray nozzle at one end of the flushing pipeline extending into the cyclone oil catcher. The dust sludge and oil separated by centrifugation enter the water seal tank through the overflow outlet. While the gas-liquid centrifugal separation is carried out, the flushing is closed, thereby avoiding the blockage of the inner wall of the device and the air outlet. The spray nozzle washing effectively speeds up the falling-off speed of the dust sludge in the centrifugal separation, reduces the adhesion condition on the inner wall of the device, realizes efficient cleaning and dust removal, and solves the problem that in the application process of the cyclone oil catcher at present, due to a large amount of dust sludge generally adhered to the inner side wall of the cyclone oil catcher, it is extremely easy to cause that the dust sludge and the air flow cannot be centrifugally separated, and finally the internal pressure of the cyclone oil catcher is unstable and difficult to dredge.

[0013] In the utility model, a tee joint and a blind plate are arranged at the elbow of the bottom pipeline of the cyclone oil catcher, effectively ensuring the convenience of dredging when the cyclone oil catcher is blocked. Brief Description of the Drawings

[0018] The following further describes the utility model with reference to the drawings and specific embodiments.

[0019] As Figure 1-2 shown, a cyclone oil catcher includes a cyclone oil catcher 1 arranged inside a cross brace 2. A flushing pipe 5 is connected through between the top of the cyclone oil catcher 1 and a hot loop water pipe 8. One end of the flushing pipe 5 extending into the inside of the cyclone oil catcher 1 is connected with a spray nozzle 6. A tee joint 14 is connected to the bottom of the cyclone oil catcher 1, and a blind plate 15 is further arranged at the bottom of the tee joint 14.

[0020] A plurality of vertical poles 3 are connected to the bottom of the cross brace 2, and reinforcing bars 4 are arranged between the vertical poles 3.

[0021] A gas inlet 9 is arranged at the top of the cyclone oil catcher 1, and an air outlet 10 is arranged at the side of the cyclone oil catcher 1.

[0022] One end of the gas inlet 9 extending into the inside of the cyclone oil separator 1 is provided with a rotating shaft 11, and the rotating shaft 11 is connected with a spiral blade 12.

[0023] The bottom of the cyclone oil separator 1 is connected with an overflow pipe 13, and the tee 14 is communicated with the overflow pipe 13.

[0024] A gate valve 7 is further arranged on the flushing pipe 5.

[0025] When the utility model is specifically applied, a flushing pipe 5 is added to the hot circulating water pipe 8. One end of the flushing pipe 5 extends to the outside of the cyclone oil separator until it enters 10 mm into the wall of the device. A spray head 6 is added at the end of the flushing pipe 5 inside the wall of the device. The water inlet spray head 6 is horizontally in the same direction as the gas inlet 9, which is convenient for the full contact of gas and liquid to carry out centrifugal separation of the gas containing oil sludge, plays a role in sedimentation and flushing of particulate matters, prevents them from sticking and caking inside the wall of the device, and is convenient for cleaning. In addition, a gate valve 7 can be added to the water inlet end of the flushing pipe 5. When the internal pressure of the cyclone oil separator fluctuates, the air outlet 10 is blocked, and the container shakes, the water inlet gate valve 7 is opened, and the water inlet spray head 6 sprays. The internal oil sludge is softened and sedimented by the hot circulating water. Part of the oil sludge is centrifugally separated and sedimented from the gas. After the gas is purified, it enters the subsequent process through the air outlet 10. The remaining small particle oil sludge and dust particles rotate with the flushing water of the spray head 6, scour the inside of the wall of the device, and carry the solid-liquid phase to rotate and flow to the lower end of the conical container, and finally are discharged through the overflow pipe 13 into the water seal tank, thereby preventing blockage. Secondly, the added flushing pipe 5 can further enhance the gas heat exchange effect. The temperature of the gas entering the cyclone oil separator from the spin flow plate tower can reach above 80 °C. The hot circulating water at about 50 °C enters the cyclone oil separator through the spray head 6 to carry out heat exchange. The lower the temperature of the gas, the higher the content of the separated oil. It further improves the oil production rate of the process for producing shale oil, and reduces the working pressure of the electric precipitator, enabling the electric precipitator to effectively trap oil. A rotating shaft 11 is added below the pipeline of the air outlet 10, and a spiral blade 12 is arranged at the bottom end. The gas and the oil-water mixture are rotationally separated through the gas inlet 9. Due to the centrifugal force, the flushing water and the oil sludge are separated and flow out through the overflow pipe 13, and the gas is extracted by negative pressure to the air outlet 10. When the gas leaves the device through the air outlet 10, the spiral blade 12 further breaks up and separates the adsorbed liquid and solid substances, thereby achieving an optimized separation effect.

[0026] Furthermore, by using the method of adding the spray head 6, the hot circulating water with a temperature of 50-80 °C is used to melt the oil sludge. Since the cyclone oil separator is placed outdoors, when the outdoor temperature is relatively low, the dust sludge and oil separated from the flue gas are more likely to harden and cake at low temperature. Through the washing of the spray head 6, the falling speed of the dust sludge in the centrifugal separation is effectively accelerated, thereby reducing its adhesion condition on the wall of the device and improving the high efficiency of dust removal and cleaning. Therefore, the cyclone oil separator has good practicability.
