Description

Technical Field

[0001] This utility model relates to the field of crude benzene recovery technology, and in particular to a crude benzene oil-water separation device and system. Background Technology

[0002] As an upstream industry of the steel industry, the coking industry is closely linked to it. Without coke, blast furnace ironmaking would be hindered, affecting the entire steel industry chain. The coking process not only produces coke but also byproducts such as coal gas, coal tar, and crude benzene. The recovery of byproducts such as tar and crude benzene can promote the formation of a "coal-coke-chemical" circular economy chain and improve the utilization efficiency of coal resources.

[0003] Currently, most projects achieve crude benzene oil-water separation by combining three devices: an oil-water separator, a control separator, and a crude benzene reflux tank. These three devices are typically vertical atmospheric pressure vessels, which have poor pressure resistance to both positive and negative pressures. When connected to a VOCs collection system, the breather valves on these devices frequently open, making it difficult to meet current environmental protection requirements for VOCs collection. Furthermore, this combination of devices has low tolerance for errors in daily production, and fluctuations in production can easily lead to poor separation of crude benzene and water.

[0004] Therefore, it is necessary to study and improve the equipment for separating crude benzene oil and water so that it can meet both environmental protection and production requirements. Utility Model Content

They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] This utility model proposes a crude benzene oil-water separation device.

[0029] Reference Figure 1 and Figure 2 In this preferred embodiment, a crude benzene oil-water separation device includes a main cylinder 1, a guide pipe 2, a baffle plate 3, and a water collector 4, wherein...

[0030] Both the main cylinder 1 and the water collector 4 are hollow inside. The baffle plate 3 is located inside the hollow cavity of the main cylinder 1, dividing it into a front chamber 12 and a rear chamber 13. The tops of the front chamber 12 and the rear chamber 13 of the main cylinder 1 are connected. The top of the front chamber 12 of the main cylinder 1 is provided with an inlet. The guide pipe 2 passes through the inlet and one end of it is inserted into the interior of the front chamber 12. The bottom wall of the rear chamber 13 is provided with a water outlet and a crude benzene outlet 11. The water collector 4 is connected below the water outlet. The water collector 4 is provided with an outlet 41. The bottom of the baffle plate 3 is provided with a square notch 31.

[0031] In this embodiment, the main cylinder 1 adopts a horizontal pressure-resistant structure (a horizontal pressure-resistant structure refers to a cylindrical cavity with elliptical outer walls at both ends), designed for pressures ranging from full vacuum to 1.0 MPa. This wide pressure range is suitable for different processes and various operating conditions, solving the problem of frequent opening of the breather valve caused by pressure fluctuations in the VOCs collection system, thereby improving VOCs recovery efficiency. In existing technologies without a pressure-resistant structure, frequent opening of the breather valve is required, leading to VOCs leakage from the breather valve.

[0032] Furthermore, a baffle 5 is provided below the guide pipe 2 on the side near the baffle plate 3. The bottom of the baffle 5 is fixed to the bottom wall of the main cylinder 1, and the width of the baffle 5 is greater than the diameter of the guide pipe 2. By adopting the structure of the baffle 5, it is possible to prevent the liquid from disturbing the already separated liquid on the side near the rear chamber 13 as soon as it enters the interior of the front chamber 12, thereby reducing disturbance and improving the oil-water separation efficiency.

[0033] Furthermore, the lower part of the guide pipe 2 has a sloping structure. The sloping structure of the guide pipe 2 is set with the left side lower and the right side higher so that the liquid in the guide pipe 2 flows away from the baffle plate 3. The sloping structure allows the liquid to move as far to the left as possible after entering the front chamber 12, minimizing the problem of oil-water interface fluctuation and back mixing in the cylinder caused by material inflow, thereby further improving the oil-water separation efficiency.

[0034] Furthermore, the distance between the bottom end of the guide pipe 2 and the inner bottom wall of the main cylinder 1 shall not exceed 150mm. This distance setting can improve the oil-water separation efficiency.

[0035] In this embodiment, a square notch 31 is also provided at the bottom of the baffle plate 3 to allow the lower layer of water separated in the front chamber 12 to enter the water collector 4. In the front chamber 12, the lower layer of water after stratification flows into the water collector 4 through the square notch 31 at the bottom of the baffle plate 3, while the upper layer of crude benzene overflows from the top of the baffle plate 3 into the rear chamber 13 and is finally discharged through the crude benzene outlet 11.

[0036] Furthermore, a self-control interface meter 6 is installed on the side wall of the water collector 4, which makes it easier for users to observe the water separation effect inside the cylinder.

[0037] In this embodiment, the water outlet is located between the baffle plate 3 and the crude benzene outlet 11; a water outlet pipe is installed on the outlet 41 of the water collector 4, and a control valve is installed on the water outlet pipe. Real-time drainage is achieved through the control valve, thereby facilitating the control of the water level in the water collector 4. The control valve is connected to the automatic interface meter 6 via a controller, thereby extending the oil-water separation time and improving the fault tolerance rate.

[0038] In this embodiment, the side of the baffle plate 3 is sealed to the side wall of the main cylinder 1, and a gap is provided between the top of the baffle plate 3 and the top wall of the main cylinder 1. The height of the gap is 1 / 2 to 3 / 5 of the height of the cylinder, and the height of the square notch 31 of the baffle plate 3 is 4cm to 6cm.

[0039] The side wall of the water collector 4 is perpendicular to the baffle plate 3. The distance between the side wall of the water collector 4 and the baffle plate 3 is 1cm to 5cm. This distance ensures that the separated water can enter the water collector 4 in a timely manner.

[0040] The crude benzene oil-water separation equipment proposed in this embodiment has the following beneficial effects:

[0041] 1. By using this crude benzene oil-water separation equipment, the problem of multiple crude benzene oil-water separation equipment and low production error rate can be solved with one equipment (by using baffle plate 3 to separate oil and water, thereby improving the error rate).

[0042] 2. Using this crude benzene oil-water separation equipment can improve product quality and production efficiency, and the effect is even better when used in conjunction with the negative pressure benzene removal process;

[0043] 3. This crude benzene oil-water separation equipment has the advantages of simple structure, easy implementation, and stable and reliable operation.

[0044] This utility model also proposes a crude benzene oil-water separation system.

[0045] In this preferred embodiment, a crude benzene oil-water separation system includes the aforementioned crude benzene oil-water separation device, and further includes a raw material supply device connected to the guide pipe 2 of the crude benzene oil-water separation device. The specific structure and beneficial effects of the crude benzene oil-water separation device are as described in the above embodiments, and will not be repeated here.

[0046] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
