Description

Technical Field

[0001] This utility model relates to the field of chemical production, and in particular to a combined high-efficiency condensation automatic drainage structure. Background Technology

[0002] In coal chemical production plants, raw coal needs to be pulverized into coal powder through a grinding process. The pulverized coal is then transported to the coal bunker for further processing. During the raw coal grinding and pulverized coal conveying stages, the process gases often contain a significant amount of moisture for production purposes. When detecting the gas composition in these stages, online analyzers frequently need to remove moisture from the sample gas to prevent it from affecting the instrument's normal operation. Currently, the most common method for removing moisture from sample gases is manual evacuation, which involves a large amount of maintenance. When production conditions change, untimely condensate removal or ineffective dehydration systems often cause analyzer malfunctions, and in severe cases, lead to interlocking shutdowns of the production unit.

[0003] These limitations may exist in the analyzer preprocessing system:

[0004] First, moisture removal often fails to achieve the desired effect and enters the instrument, causing analyzer malfunction, affecting analyzer data, and even causing a chain reaction shutdown of production equipment.

[0005] Secondly, there is the issue of condensate removal from the sample gas. Previously, this was done manually, which involved a lot of maintenance work. When production conditions changed, the condensate was often not removed in time, causing analyzer malfunctions or even production unit shutdowns due to interlocking. Utility Model Content

[0006] The purpose of this invention is to provide a combined, high-efficiency, automatic condensation and drainage structure to solve the above-mentioned problems.

[0007] This utility model achieves the above objectives through the following technical solutions:

[0008] A combined high-efficiency condenser automatic drain structure includes a vortex cooler for heat exchange, a condensate collection tank for collecting condensate, and an automatic drain tank for intermittent drainage. The vortex cooler is installed inside the heat exchange chamber. A sample inlet pipeline is connected to the top of the vortex cooler, and the condensate collection tank is connected to the bottom of the vortex cooler through a pipeline. A cold air inlet pipe is connected to the top of one end of the vortex cooler, and a cold air outlet is connected to the bottom of the other end of the vortex cooler.

[0009] The condensate collection tank has a dry sample outlet on the side away from the vortex cooler. The dry sample outlet is located inside the condensate collection tank and connected to a hydrophilic filter. The other end of the dry sample outlet extends out of the condensate collection tank. The bottom of the condensate collection tank is connected to the top of the automatic drain tank through a pipe. A drain float is provided on the bottom side of the automatic drain tank. A condensate discharge pipeline is provided at the bottom of the drain float. The bottom of the drain float is connected to the automatic drain tank through a conical sealing ring.

[0010] Preferably, the scroll cooler has a spiral tube structure.

[0011] Preferably, the cold air outlet is connected to the heat exchange chamber by welding.

[0012] Preferably, the hydrophilic filter is connected to the dried sample outlet via a thread, and the dried sample outlet is connected to the condensate collection tank via a flange.

[0013] Preferably, the condensate discharge line is connected to the automatic discharge tank via a threaded connection.

[0014] Preferably, the drainage float is a hollow sphere.

[0015] Preferably, the conical ring at the bottom of the drain float is made of rubber.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This solution modifies the original pretreatment structure, replacing the ordinary liquid collection tank with a cold condensation tank and adding an automatic liquid draining tank. This improves the removal efficiency of moisture in the sample gas, eliminates manual liquid draining operations, reduces equipment failure rate, increases equipment online rate, and enables the equipment to operate stably for a long time.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-3 As shown, a combined high-efficiency condenser automatic drain structure includes a vortex cooler 1 for heat exchange, a condensate collection tank 7 for collecting condensate, and an automatic drain tank 9 for intermittent drainage. The vortex cooler 1 is installed inside the heat exchange chamber 6. The top of the vortex cooler 1 is connected to a sample inlet pipe 3, and the bottom of the vortex cooler 1 is connected to the condensate collection tank 7 through a pipe. The top of one end of the vortex cooler 1 is connected to a cold air inlet pipe, and the bottom of the other end of the vortex cooler 1 is connected to a cold air outlet 2.

[0028] A dry sample outlet 4 is provided on the side of the condensate collection tank 7 away from the vortex cooler 1. The dry sample outlet 4 is located inside the condensate collection tank 7 and is connected to a hydrophilic filter screen 8. The other end of the dry sample outlet 4 extends out of the condensate collection tank 7. The bottom of the condensate collection tank 7 is connected to the top of the automatic drain tank 9 through a pipe. A drain float 10 is provided on the bottom side of the automatic drain tank 9. A condensate discharge pipeline 5 is provided at the bottom of the drain float 10. The bottom of the drain float 10 is connected to the automatic drain tank 9 through a conical sealing ring.

[0029] In this embodiment, the scroll cooler 1 has a spiral tube structure.

[0030] In this embodiment, the cold air outlet 2 is connected to the heat exchange chamber 6 by welding.

[0031] In this embodiment, the hydrophilic filter 8 is connected to the dry sample outlet 4 via a thread, and the dry sample outlet 4 is connected to the condensate collection tank 7 via a flange.

[0032] In this embodiment, the condensate discharge line 5 is connected to the automatic discharge tank 9 via a threaded connection.

[0033] In this embodiment, the drainage float 10 is a hollow sphere structure.

[0034] In this embodiment, the conical ring at the bottom of the drainage float 10 is made of rubber.

[0035] Working principle: When the equipment is running, the cold air inlet pipe is connected to the external cold air source, and the cold air outlet 2 is connected to the external cold air recovery component (not shown). The sample enters the vortex cooler 1 through the sample inlet pipe 3. Inside the heat exchange chamber 6, the sample gas is rapidly cooled to the dew point temperature. As the temperature of the sample gas decreases, some water vapor is converted into liquid water droplets.

[0036] After heat exchange, the gas enters the condensate collection tank 7 and water droplets are further precipitated on the surface of the hydrophilic filter screen 8, making the gas drier and meeting the equipment usage requirements.

[0037] The condensate flowing out of the condensate collection tank 7 enters the automatic drain tank 9 through the pipeline. When the condensate in the automatic drain tank 9 reaches a certain level, the drain float 10 is lifted by buoyancy, and the liquid is discharged from the condensate discharge pipeline 5. When the liquid is discharged, the drain float 10 automatically falls down, closing the drain outlet and preventing air from entering.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
