Description

Technical Field

[0001] This utility model belongs to the technical field of material separation equipment, and in particular relates to a system for separating high-density materials and water in a storage tank. Background Technology

[0002] In chemical production processes, it is often necessary to separate mixtures of high-density materials and water. When such mixtures enter storage tanks, they naturally stratify due to density differences: the high-density materials settle to the bottom due to gravity, while the aqueous phase remains on top. Traditional separation methods mainly rely on manual operation, which has the following significant drawbacks: (1) Low separation accuracy, which can easily lead to material waste or pollution: Manually judging the layer interface through the observation window and relying on experience to control the discharge valve makes it difficult to accurately distinguish between the material and the water phase, often resulting in the water phase being mixed into the lower layer material (reducing the purity of the material) or the upper water phase carrying material (causing waste and subsequent processing burden). (2) Operation relies on manual labor, which is inefficient and risky: It requires dedicated personnel to continuously monitor the liquid level and stratification status of the storage tank, and manually open and close valves to adjust the feeding and discharging. This not only increases labor costs, but may also cause the liquid level to overflow due to excessively high levels (causing safety hazards) or affect the continuity of separation due to excessively low levels. (3) Monitoring and control are disconnected and lack of automated linkage: Most existing storage tanks are only equipped with simple level gauges or density gauges, which cannot form a closed-loop control with the feed and discharge valves. When the properties of the material fluctuate (such as the density shifts due to temperature changes), misjudgment is likely to occur, leading to separation failure. (4) Inconvenient emergency response and maintenance: There is no manual control backup mechanism. When the automatic system fails, it is not possible to quickly switch to manual operation. At the same time, the direct emission of exhaust gas may cause environmental pollution, and the flow of materials in the pipeline is difficult to observe intuitively, making it difficult to detect blockage or mixing problems in a timely manner.

[0003] The aforementioned problems make it difficult for traditional separation systems to meet the demands of efficient, precise, continuous, and environmentally friendly production when handling high-density material-water mixtures. There is an urgent need for a separation system that integrates automated control, precise monitoring, and convenient operation. Summary of the Invention

[0004] To address the problems in the prior art, this utility model provides a system for separating high-density materials and water in a storage tank. The technical solution includes a material inlet pipe connected to the top of the storage tank. The top of the storage tank is also equipped with a remote level gauge and a tail gas discharge pipe. The bottom of the storage tank is equipped with a main discharge pipe. The material inlet pipe is equipped with an inlet shut-off valve, and the main discharge pipe is equipped with a discharge shut-off valve and a five-way sight glass. A remote density gauge is installed at one interface of the five-way sight glass. The main discharge pipe is connected to both a material discharge pipe and a wastewater discharge pipe via a T-junction. The material discharge pipe is equipped with a material shut-off valve, and the wastewater discharge pipe is equipped with a wastewater shut-off valve.

[0005] In a preferred embodiment, the remote level gauge is interlocked with the feed shut-off valve and the discharge shut-off valve, and the remote level gauge controls the opening and closing of the feed shut-off valve and the discharge shut-off valve according to the level information.

[0006] In a preferred embodiment, the remote density meter is interlocked with the material shut-off valve and the wastewater shut-off valve, and the remote density meter controls the opening and closing of the material shut-off valve and the wastewater shut-off valve based on the density information.

[0007] As a preferred embodiment, the storage tank is also provided with an observation window on its body.

[0008] In a preferred embodiment, a first manual valve is provided on the side of the material inlet pipe near the storage tank.

[0009] In a preferred embodiment, a second manual valve is also provided between the remote level gauge and the storage tank.

[0010] In a preferred embodiment, the exhaust pipe is equipped with a third manual valve.

[0011] In a preferred embodiment, a fourth hand valve is provided on the side of the discharge main pipe near the storage tank.

[0012] In a preferred embodiment, the material discharge pipe is also equipped with a fifth manual valve.

[0013] In a preferred embodiment, the wastewater discharge pipe is also equipped with a sixth manual valve.

[0014] The beneficial effects of this utility model are: (1) The system can directly observe the material status in the pipeline through the five-way sight glass, and monitor the density change in real time with the remote density meter. The density meter is interlocked with the material shut-off valve and the wastewater shut-off valve, and can automatically and accurately switch the discharge path according to the density difference. When high-density material is detected, the shut-off valve of the material discharge pipe is opened; when water phase is detected, the shut-off valve of the wastewater discharge pipe is opened, thus completely avoiding the problem of mixed discharge caused by human judgment error. (2) The remote level gauge is interlocked with the feed shut-off valve and the discharge shut-off valve, which can automatically adjust the feed and discharge according to the real-time liquid level in the storage tank: when the liquid level is too high, the feed valve is closed and the discharge valve is opened; when the liquid level is too low, the opposite is true. This avoids the risk of overflow or empty tank caused by untimely manual monitoring, reduces labor costs, and makes the separation process continuous and stable. (3) The first to sixth manual valves and five-way sight glasses are respectively installed on the storage tank, material inlet pipe, remote level gauge, tail gas outlet pipe, discharge main pipe, material outlet pipe and wastewater outlet pipe as backup mechanisms for the automatic system. When the remote instrument or interlock control fails, it can be quickly adjusted through the manual valve to ensure that the separation process is not interrupted. At the same time, the manual valve facilitates isolation operation during equipment maintenance and improves the convenience of system maintenance. (4) A tail gas exhaust pipe is installed on the top of the storage tank, which can collect and treat the volatiles generated during the separation process in a directional manner, avoiding environmental pollution caused by direct discharge; the observation window provides a real-time visualization window, which makes it easy for operators to intuitively observe the material flow and stratification status, assist in judging whether the system is operating normally, and reduce the risk of hidden faults.

It includes a material inlet pipe 1, which is connected to the top of a storage tank 4. The top of the storage tank 4 is also equipped with a remote level gauge 3 and a tail gas exhaust pipe 5. The bottom of the storage tank 4 is equipped with a discharge main pipe 6. The material inlet pipe 1 is equipped with a feed shut-off valve 2, and the discharge main pipe 6 is equipped with a discharge shut-off valve 7 and a five-way sight glass 8. A remote density gauge 9 is installed at one interface of the five-way sight glass 8. The discharge main pipe 6 is connected to a material discharge pipe 10 and a wastewater discharge pipe 11 via a tee. The material discharge pipe 10 is equipped with a material shut-off valve 11, and the wastewater discharge pipe 12 is equipped with a wastewater shut-off valve 13.

[0019] The mixture (mainly ethyl difluoroacetate and water) is poured into the storage tank 4 through the material inlet pipe 1. After standing for a period of time, the liquid in the storage tank 4 is checked by the observation mirror 20 to determine whether the liquid has completed stratification. After stratification, the discharge shut-off valve 7 and the material shut-off valve 11 are opened by remote activation to discharge the high-density material through the material discharge pipe 10. When the remote density meter 3 detects that the density is less than the set value, the material shut-off valve 11 is closed and the wastewater shut-off valve 13 is activated to discharge the wastewater through the wastewater discharge pipe 12 to the sewage treatment plant.

[0020] Furthermore, the remote level gauge 3 is interlocked with the feed shut-off valve 2 and the discharge shut-off valve 7, and the remote level gauge 3 controls the opening and closing of the feed shut-off valve 2 and the discharge shut-off valve 7 according to the level information.

[0021] When the liquid level in storage tank 4 drops to the lower threshold, the remote level gauge 3 closes the discharge shut-off valve 7 and starts the inlet shut-off valve 2 for filling. When the liquid level reaches the upper threshold, the inlet shut-off valve 2 is closed. After settling, the water separation operation is performed.

[0022] Furthermore, the remote density meter 9 is interlocked with the material shut-off valve 11 and the wastewater shut-off valve 13, and the remote density meter 9 controls the opening and closing of the material shut-off valve 11 and the wastewater shut-off valve 13 according to the density information.

[0023] When the remote density meter 9 detects a density greater than the specified value, it activates the material shut-off valve 11 and closes the wastewater shut-off valve 13; conversely, it closes the material shut-off valve 11 and activates the wastewater shut-off valve 13.

[0024] Furthermore, the tank body of the storage tank 4 is also provided with an observation window 20 for observing whether the mixed liquid in the storage tank 4 has successfully separated into layers.

[0025] Furthermore, a first hand valve 14 is provided on the side of the material inlet pipe 1 near the storage tank 4.

[0026] Furthermore, a second hand valve 15 is also provided between the remote level gauge 3 and the storage tank 4.

[0027] Furthermore, a third manual valve 16 is provided on the exhaust pipe 5.

[0028] Furthermore, a fourth hand valve 17 is provided on the side of the discharge main pipe 6 near the storage tank 4.

[0029] Furthermore, the material discharge pipe 10 is also equipped with a fifth manual valve 18.

[0030] Furthermore, a sixth manual valve 19 is also provided on the wastewater discharge pipe 12.

[0031] The first to sixth manual valves and the five-way viewing window 8 mentioned above are used for manual liquid separation or replacement of parts during maintenance or system failure.
