Description

Technical Field

[0001] This utility model relates to the field of gas online analyzer technology, and in particular to a pre-water removal device suitable for online analyzers. Background Technology

[0002] An online gas analyzer, also known as a process gas analyzer, is an instrument that is directly installed in an industrial production process or environmental monitoring site to continuously, automatically, and in real-time measure and analyze gas components. The inlet of an online gas analyzer is usually directly connected to the gas pipeline via a sampling tube. However, the gas in industrial gas pipelines is typically pressurized and liquid. Directly introducing this gas into the online gas analyzer through the sampling tube can damage the internal components and affect the measurement results, potentially rendering the analyzer unusable. Utility Model Content

[0003] The purpose of this invention is to provide a pre-treatment dehydration device suitable for online gas analyzers, in order to solve the problems existing in the prior art.

[0004] This utility model is implemented by the following technical solution: A pre-treatment dehydration device suitable for an online gas analyzer, comprising a tank, a drying tank, a gas guide pipe, and a housing. A medium inlet is connected to the top air inlet of the tank via an inlet pipe. A first pressure reducing valve and an inlet valve are sequentially arranged along the gas flow direction on the inlet pipe. A gas guide pipe is installed inside the tank, with its top inlet connected to the outlet of the inlet pipe, and its outlet extending to the lower part of the tank. The bottom of the tank is connected to a drain outlet via a drain pipe, and a drain valve is installed on the drain pipe. The side of the tank body is connected to the drain outlet via a drain pipe, and a drain valve is installed on the drain pipe; the exhaust port at the top of the tank body is connected to the inlet of the drying tank via an exhaust pipe, and a second pressure reducing valve is installed on the exhaust pipe; the outlet of the drying tank is connected to the medium outlet via an outlet pipe; a steam tracing coil is installed on the back of the box body, and the tank body and the drying tank are located inside the box body; the medium inlet and the medium outlet are both located on the outside of the side wall of the box body; the sewage outlet and the drain outlet are both located on the outside of the bottom of the box body; the air guide pipe is a serpentine pipe or a spiral pipe.

[0005] Furthermore, it includes two drying tanks, the inlets of the two drying tanks are respectively connected to the outlet end of the exhaust pipe through a first branch pipe, and a drying inlet valve is installed on the first branch pipe; the outlets of the two drying tanks are connected to the inlet of the outlet pipe through a three-way valve.

[0006] Furthermore, an exhaust buffer tank is provided between the exhaust port at the top of the tank and the inlet of the exhaust pipe. Furthermore, a drainage buffer tank is provided between the outlet end of the drain pipe and the drain outlet.

[0007] The advantages of this invention are as follows: A tank is installed before the drying tank. The gas medium enters the tank through a gas guide pipe to achieve preliminary gas-liquid separation, which reduces the moisture content of the gas entering the drying tank, further enhancing the drying effect. This completely removes moisture from the gas, preventing damage to online analysis equipment, ensuring the accuracy of measurement data, and providing reliable data support for safe and stable production. Furthermore, the internal temperature of the tank can be adjusted through the insulation jacket, thereby meeting the gas-liquid separation requirements of different media.

Detailed Implementation

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] like Figure 1 and Figure 2As shown, a pre-treatment dehydration device suitable for an online gas analyzer includes a tank 1, a drying tank 2, and a gas guide pipe 3. A medium inlet 4 is connected to the top air inlet of the tank 1 via an inlet pipe 5. A first pressure reducing valve 7 and an inlet valve 6 are sequentially arranged on the inlet pipe 5 along the gas flow direction. The gas guide pipe 3 is located inside the tank 1, with its top inlet connected to the outlet of the inlet pipe 5, and its outlet extending to the lower part of the tank 1. The gas guide pipe 3 is either a serpentine pipe or a spiral pipe; in this embodiment, it is a serpentine pipe. The bottom of the tank 1 is connected to a drain outlet 9 via a drain pipe 8, and a drain valve 10 is installed on the drain pipe 8. The side of the tank 1 is connected to a drain outlet 12 via a drain pipe 11, and a drain valve 13 is installed on the drain pipe 11. A drainage buffer tank 22 is located between the outlet of the drain pipe 11 and the drain outlet 12 to buffer the liquid. The exhaust port at the top of tank 1 is connected to the inlet of drying tank 2 via exhaust pipe 14, and a second pressure reducing valve 15 is installed on exhaust pipe 14; the outlet of drying tank 2 is connected to medium outlet 17 via outlet pipe 16. An exhaust buffer tank 21 is installed between the exhaust port at the top of tank 1 and the inlet of exhaust pipe 14 to buffer the gas. It includes two drying tanks 2, the inlets of which are connected to the outlet of the exhaust pipe 14 via a first branch pipe 18, and a drying inlet valve 19 is installed on the first branch pipe 18; the outlets of the two drying tanks 2 are connected to the inlet of the outlet pipe 16 via a three-way valve 20. The two drying tanks 2 are filled with silica gel desiccant, and one tank is kept as a spare. By switching the drying inlet valve 19 and the three-way valve 20, the spare drying tank 2 can be removed and dried using a high-temperature baking method, achieving reuse.

[0013] It also includes a housing 23, with a steam tracing coil 24 installed on the back of the housing 23. The tank 1 and the drying tank 2 are located inside the housing 23. The medium inlet 4 and the medium outlet 17 are both located on the outside of the side wall of the housing 23. The drain outlet 9 and the drain 12 are both located on the outside of the bottom of the housing 23. By placing the tank 1, the drying tank 2, and related pipelines and valves inside the housing 23, the internal temperature of the housing 23 can be regulated by introducing steam through the steam tracing coil 24, thus meeting the gas-liquid separation requirements of different media.

[0014] Instructions for use: Connect the medium inlet 4 to the sampling tube outlet, and the medium outlet 17 to the inlet of the online gas analyzer. The gas to be tested enters the medium inlet 4 through the sampling tube, and then, after being adjusted to a suitable pressure by the first pressure reducing valve 7 on the inlet pipeline 5, the inlet valve 6 is opened, allowing the gas to enter the lower part of the tank 1 through the gas guide pipe 3. During the process of the gas rising in the tank 1, preliminary gas-liquid separation occurs. The separated liquid gathers at the lower part of the tank 1, while the separated gas flows upward and enters the exhaust buffer tank 21 for buffering. After being adjusted to a suitable pressure by the second pressure reducing valve 15, the drying inlet valve 19 corresponding to any drying tank 2 is opened, and the three-way valve is adjusted to connect the corresponding drying tank 2 and the outlet pipeline 16. The gas in the exhaust buffer tank 21 is dried by the drying tank 2 and then enters the online gas analyzer through the outlet pipeline 16 and the medium outlet 17. After that, the drying inlet valve 19 is closed.

[0015] When drainage is required, open the drain valve 13. The liquid collected in tank 1 will flow through the drain pipe 11 into the drainage buffer tank 22 for buffering, and then be discharged from the equipment through the drain outlet 12. After that, close the drain valve 13. In addition, periodically open the drain valve 10 to discharge the material accumulated at the bottom of tank 1 from the equipment through the drain pipe 8.
