Description

Technical Field

[0001] This utility model relates to the field of graphite equipment monitoring technology, and in particular to an online monitoring device for graphite equipment operation. Background Technology

[0002] Graphite coolers are a special type of heat exchanger widely used in chemical, pharmaceutical, metallurgical, pesticide, and dye industries. They are particularly suitable for handling highly corrosive media. In chlor-alkali industries or organic chlorination reactions, high-temperature hydrogen chloride gas is generated. This gas needs to be cooled before subsequent absorption for acid production or processing. High-temperature HCl gas is extremely corrosive; ordinary stainless steel will corrode rapidly, while graphite materials exhibit perfect resistance to this environment.

[0003] In the current process of using water to cool hydrogen chloride gas through graphite heat exchangers, if the graphite heat exchanger ruptures and leaks due to factors such as corrosion, stress, or material fatigue, but there are no leak monitoring measures for the graphite heat exchanger, requiring personnel to conduct regular inspections, these inspections cannot detect leaks in a timely manner. This cannot prevent leaks from causing mixing between the cooling water and the highly corrosive hydrogen chloride gas. Water entering the process gas side can cause hydrochloric acid to condense, which may then corrode non-corrosion-resistant downstream equipment and pipelines, causing secondary damage. Utility Model Content

[0004] The purpose of this invention is to overcome the current situation where leaks in graphite heat exchange equipment cannot be detected in time, leading to cross-contamination of media, and to propose an online monitoring device for graphite equipment operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An online monitoring device for graphite equipment operation includes a graphite cooler, a first inlet of which is connected to a material inlet pipeline, a first outlet of which is connected to a material outlet pipeline, a third outlet of which is connected to a sewage discharge pipeline, and an outlet of the sewage discharge pipeline is connected to a liquid collection tank, with a liquid level monitoring sensor connected inside the liquid collection tank.

[0006] When the graphite cooler is damaged internally, the cooling medium will enter the drain pipe along with the material and flow into the liquid collection tank. The liquid level monitoring sensor detects the changes in the liquid level in the tank in real time. When the liquid level exceeds the set threshold, an alarm signal is issued, thereby promptly detecting equipment leakage and preventing media from mixing and subsequent equipment corrosion damage.

[0007] Preferably, the second inlet of the graphite cooler is connected to a cooling medium inlet pipeline, and the second outlet of the graphite cooler is connected to a cooling medium outlet pipeline.

[0008] Cooling medium is supplied to the graphite cooler through the cooling medium inlet pipeline, and the material in the graphite cooler is cooled down before being discharged through the cooling medium outlet pipeline.

[0009] Preferably, the cooling medium outlet pipeline is provided with two cooling medium outlet valves and a sight glass, with the sight glass located between the two cooling medium outlet valves.

[0010] The sight glass allows staff to easily observe the flow of the medium inside the pipeline, and the two cooling medium outlet valves can be configured according to site conditions, allowing the corresponding cooling medium outlet valves to be opened or closed.

[0011] Preferably, a material outlet shut-off valve is installed on the material outlet pipeline.

[0012] Preferably, a sewage discharge valve is installed on the sewage discharge pipeline.

[0013] Preferably, the liquid level monitoring sensor is a magnetic float level gauge.

[0014] The magnetic float level gauge provides effective protection against corrosive media and can operate stably for a long time in strong acid environments.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by installing a liquid collection tank and setting a liquid level monitoring sensor at the bottom drain of the graphite heat exchanger, when the graphite heat exchanger leaks, the liquid level monitoring sensor detects the change in liquid level in the tank in real time and then issues an alarm, which can detect equipment leaks in time and take timely measures, thus solving the problem of media cross-contamination caused by the failure to detect and deal with graphite heat exchanger leaks in time, which threatens safe production.

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] Reference Figure 1 An online monitoring device for graphite equipment operation includes a graphite cooler 1. The first inlet of the graphite cooler 1 is connected to a material inlet pipeline 3, which transports hydrogen chloride gas requiring cooling. The first outlet of the graphite cooler 1 is connected to a material outlet pipeline 2, through which the cooled gas is discharged. A material outlet shut-off valve 7 is installed on the material outlet pipeline 2 to quickly close the valve, preventing the discharge of uncooled material and ensuring subsequent processing. The third outlet of the graphite cooler 1 is connected to a drain pipeline 10. When the graphite cooler 1 is damaged, under the pressure of the gas, the gas... The combined liquid is transported to the liquid collection tank 8 through the drain line 10. The drain line 10 is equipped with a drain line valve 11, which is always open. When the graphite cooler 1 is damaged, it facilitates the rapid discharge of the material inside the graphite cooler 1. The liquid level monitoring sensor 9 detects the solution and triggers an alarm, achieving rapid feedback. The outlet of the drain line 10 is connected to the liquid collection tank 8, and the liquid level monitoring sensor 9 is connected inside the liquid collection tank 8. The liquid level monitoring sensor 9 is a magnetic float level gauge, which provides effective protection against corrosive media and can operate stably for a long time in a strong acid environment.

[0021] Reference Figure 1 The second inlet of the graphite cooler 1 is connected to a cooling medium inlet pipeline 12, and the second outlet of the graphite cooler 1 is connected to a cooling medium outlet pipeline 6. The cooling medium inlet pipeline 12 transports the medium, which cools the hydrogen chloride gas in the graphite cooler 1. The cooling medium outlet pipeline 6 is equipped with two cooling medium outlet valves 4 and a sight glass 5. The sight glass 5 is located between the two cooling medium outlet valves 4. The sight glass 5 allows the operator to directly observe the flow status of the medium in the cooling medium outlet pipeline 6. The two cooling medium outlet valves 4 can be set according to the site conditions, opening or closing the corresponding cooling medium outlet valves 4.

[0022] During operation, material inlet pipeline 3 delivers hydrogen chloride that needs to be condensed, while cooling medium inlet pipeline 12 delivers condensate. The condensate and hydrogen chloride are then delivered to graphite cooler 1, where the condensate cools the hydrogen chloride. When the graphite cooler 1 is damaged, the mixed hydrogen chloride solution is delivered to liquid collection tank 8 through drain pipeline 10. Liquid collection tank 8 is equipped with a liquid level monitoring sensor 9. When the liquid level in liquid collection tank 8 is detected, an alarm signal is issued when the liquid level exceeds a set threshold, thus promptly detecting equipment leaks and preventing cross-contamination of media and subsequent equipment corrosion damage. The operator closes the material outlet shut-off valve 7 on material outlet pipeline 2 and the cooling medium outlet valve 4 on cooling medium outlet pipeline 6, while simultaneously closing the valves on material inlet pipeline 3 and cooling medium inlet pipeline 12, to perform maintenance on graphite cooler 1.
