Description

Technical Field

[0001] This utility model relates to the field of petroleum processing technology, and in particular to an automatic drainage device. Background Technology

[0002] In the production and operation processes of industries such as petroleum and chemicals, situations often arise where liquids and water are mixed, and effectively separating the two is of great importance. For example, in oil extraction, the produced fluids from oil wells contain crude oil, associated water, and impurities such as silt that may be mixed in. If the water is not separated in time, it will not only increase the difficulty and cost of subsequent crude oil processing, but may also lead to problems such as pipeline corrosion and equipment failure due to excessive water content. In chemical production processes, many mixed systems after chemical reactions contain organic and aqueous phases. Accurate separation is necessary to ensure product quality, and drainage devices are required.

[0003] In existing technologies, drainage mostly relies on manual valve control and visual observation to determine whether the water has been drained. This is not conducive to unattended operation, the control is not precise enough, and it results in a waste of resources. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where drainage largely relies on manual valve control and visual observation of whether the water has been drained, which is not conducive to unattended operation, lacks precision in control, and results in resource waste. Therefore, an automatic drainage device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic drainage device, comprising:

[0007] Mounting housing;

[0008] The real-time monitoring mechanism includes a transfer box fixed to the bottom of the mounting housing. The transfer box is vertically connected in a first direction to an inlet pipe with one end located at the bottom of the mounting housing. The end of the inlet pipe along the height direction of the transfer box and corresponding to the lower end of the mounting housing is flared. The mounting housing is fixed with a water content sensor with one end extending into the inlet pipe and a signal converter installed on top of the water content sensor and located inside the mounting housing. A temperature sensor is fixed between the mounting housing and the transfer box.

[0009] Furthermore, the transfer box is fixedly provided with an outlet pipe along its length and with a diameter and height consistent with the height of the flared opening.

[0010] Furthermore, a storage tank is provided on the side of the transfer box away from the outlet pipe, and a pipe body and an electric valve provided on the pipe body are connected between the storage tank and the inlet pipe.

[0011] Furthermore, the first tube body is connected to the second tube body, which is connected to the mounting shell, and a control panel disposed on the second tube body.

[0012] Furthermore, one end of the outlet pipe is connected to a wastewater pool.

[0014] 1. This solution automatically determines whether the water has been drained when separating water from a liquid, and automatically controls the opening and closing of the valve;

[0015] 2. This solution enables DCS communication and unattended operation. Moisture content can be set from 1% to 20%, providing precise control and saving raw materials. Attached Figure Description

[0022] Reference Figures 1-2 An automatic drainage device, comprising:

[0023] Mounting shell 4;

[0024] The real-time monitoring mechanism includes a transfer box 12 fixed to the bottom of the mounting housing 4. The transfer box 12 is vertically connected to an inlet pipe 1 at one end located at the bottom of the mounting housing 4 in the first direction. The end of the inlet pipe 1 along the height direction of the transfer box 12 and corresponding to the lower end of the mounting housing 4 is shaped like a flared mouth 2. The mounting housing 4 is fixed with a water content sensor 5 extending into the inlet pipe 1 at one end and a signal converter 7 installed on top of the water content sensor 5 and located inside the mounting housing 4. The water content sensor 5 measures the difference in dielectric constant of different media to distinguish between water and raw materials. A temperature sensor 6 is fixed between the mounting housing 4 and the transfer box 12. The temperature sensor 6 is used to compensate for the water content sensor 5 because the dielectric constant changes with different temperatures.

[0025] In this embodiment, the transfer box 12 is fixed with an outlet pipe 3 along its length and with a diameter and height consistent with the height of the flared mouth 2. The design of the inlet pipe 1, the flared mouth 2 and the outlet pipe 3 can continuously flush the water content sensor 5, so as to prevent it from being affected by material buildup and maintain high-precision measurement.

[0026] In this embodiment, a storage tank 8 is provided on the side of the transfer box 12 away from the outlet pipe 3. The storage tank 8 is connected to the inlet pipe 1 by a pipe body and an electric valve 9 installed on the pipe body.

[0027] In this embodiment, a second pipe body that is connected to the mounting shell 4 and a control panel 10 disposed on the second pipe body are connected to the first pipe body.

[0028] In this embodiment, one end of the outlet pipe 3 is connected to the wastewater pool 11.

[0029] The implementation principle of the automatic drainage device in this embodiment is as follows: When the storage tank 8 has been stationary for the set period of the control board, the control board opens the electric valve 9. At this time, liquid enters from the inlet pipe 1, and at the same time, it can continuously flush the water content sensor 5 to prevent it from being affected by material buildup and maintain high-precision measurement. The water that enters can overflow from the flare port 2 and enter the transfer box 12 after contacting the temperature sensor 6. The temperature sensor 6 is used to compensate for the water content sensor 5. The specific conversion formula for the change in dielectric constant due to different temperatures is as follows:

[0030] For pure water (0°C ≤ TT ≤ 100°C), the empirical formula for the static dielectric constant is:

[0031] εr(T)=87.74−0.40008⋅T+9.398×10−4⋅T2−1.410×10−6⋅T3εr;

[0032] (T)=87.74−0.40008⋅T+9.398×10−4⋅T2−1.410×10−6⋅T3;

[0033] parameter:

[0034] oTT: Temperature (unit: °C)

[0035] εr(T): Static dielectric constant (dimensionless) at temperature T.

[0036] Water passing through temperature sensor 6 flows out through outlet pipe 3 to wastewater pool 11. When the control panel 10 receives feedback from water content sensor 5 that the percentage water content value reaches the set parameter, it closes electric valve 9 to complete one automatic drainage cycle. This device design enables DCS communication, unattended operation, and the water content can be set from 1% to 20%, providing precise control and saving raw materials.

[0037] All structures in this application can be customized in terms of material and length according to actual usage. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted accordingly.

[0038] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
