Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separation technology, and more specifically, to an intelligent transmitter gas-liquid separation device. Background Technology

[0002] In the field of industrial process control, intelligent pressure transmitters are widely used for pressure monitoring in liquid pipelines. They connect to the pipeline via pressure tapping valves to transmit pressure signals in real time. However, when the fluid in the pipeline contains a small amount of gas (such as water-containing gas, gas bubbles, or gas-liquid two-phase flow), the gas-liquid mixture can easily enter the transmitter's sensing chamber through the pressure tapping valve. The long-term accumulation of liquid components (especially water vapor) can lead to the following problems:

[0003] Transmitter accuracy deterioration: Droplets adhere to the sensor diaphragm, affecting the accurate transmission of pressure signals;

[0004] Increased equipment failure rate: Liquid corrosion of circuit components or failure of seals;

[0005] Increased maintenance costs: Frequent shutdowns are required for cleaning or replacement of transmitters.

[0006] Traditional solutions include adding a gravity settling separator or a mechanical filter to the front end of the transmitter, but these methods have drawbacks such as low separation efficiency, large size, and easy clogging, and cannot meet the requirements of low flow rate and high gas-liquid mixing ratio.

[0007] Therefore, there is an urgent need for an intelligent transmitter gas-liquid separation device to solve the above problems. Utility Model Content

[0008] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide an intelligent transmitter gas-liquid separation device. By incorporating a gas-liquid separator body, a drain pipe, a microcontroller, and a liquid level sensor, this utility model can separate micron-sized droplets by centrifugal force with a separation efficiency of over 99%, significantly reducing the transmitter failure rate. Simultaneously, automatic drainage reduces manual intervention, extending the maintenance cycle by over 50%. Its volume is only 1 / 5 that of a traditional settling tank, making it suitable for narrow pipe spaces. The separation effect is stable, thus solving the problems mentioned in the background art.

[0018] As attached Figure 1 and attached Figure 2 As shown, this utility model provides an intelligent transmitter gas-liquid separation device, including a gas-liquid separator body 1. A lower pressure guide pipe 2 is fixedly installed on one side of the bottom of the gas-liquid separator body 1. The bottom end of the lower pressure guide pipe 2 is connected to an external pipeline. A pressure tapping valve 3 is fixedly installed on the lower pressure guide pipe 2. A drain pipe 4 is fixedly installed at the bottom of the gas-liquid separator body 1. A drain valve 5 is fixedly installed on the drain pipe 4. An upper pressure guide pipe 6 is fixedly installed on one side of the top of the gas-liquid separator body 1. An intelligent pressure transmitter 7 is fixedly installed at one end of the upper pressure guide pipe 6. An adjustable guide plate is provided inside the connection between the lower pressure guide pipe 2 and the gas-liquid separator body 1. The gas-liquid separator body 1 has multiple spiral guide vanes inside its swirling chamber, which are evenly distributed in a turbine shape. The inner wall of the swirling chamber inside the gas-liquid separator body 1 is coated with a hydrophobic coating. A liquid collection tank is located at the bottom of the gas-liquid separator body 1, and a liquid level sensor is installed inside the liquid collection tank. The drain pipe 4 is connected to the liquid collection tank. The output end of the liquid level sensor is connected to a microcontroller. The output end of the microcontroller is connected to the input end of the drain valve 5. An alarm module is connected to the output end of the microcontroller. A WiFi module is connected to the output end of the microcontroller. A remote monitoring terminal is connected to the output end of the WiFi module.

[0019] The adjustable guide plate includes a guide plate and a micro servo motor, and the output shaft of the micro servo motor is connected to the guide plate in a transmission manner.

[0020] The lower pressure guide pipe 2 is connected to an external pipeline;

[0021] The microcontroller is designated as M68HC16. A microcontroller is an integrated circuit chip that uses very large-scale integrated circuit technology to integrate a central processing unit (CPU), random access memory (RAM), read-only memory (ROM), various I / O ports, interrupt system, timers / counters, and other functions onto a single silicon chip, forming a small but complete microcomputer system. The WiFi module is designated as TLN13UA06. A WiFi module, also known as a serial Wi-Fi module, belongs to the Internet of Things (IoT) transmission layer. Its function is to convert serial or TTL levels into embedded modules that conform to the Wi-Fi wireless network communication standard. It has a built-in wireless network protocol stack of IEEE 802.11b.gn and a TCP / IP protocol stack. The liquid level sensor is designated as JYB-KO-L. A liquid level sensor is a pressure sensor that measures liquid level. Based on the principle that the measured liquid static pressure is proportional to the liquid height, it uses an isolated diffused silicon sensing element or a ceramic capacitor pressure sensing sensor to convert static pressure into an electrical signal. After temperature compensation and linear correction, it is converted into a standard electrical signal (generally 4-20mA / 1-5VDC).

[0022] The specific implementation method is as follows: When using this utility model, the cyclone separation chamber of the gas-liquid separator body 1 adopts a gradually narrowing and expanding flow channel design, and is equipped with spiral guide vanes inside. The centrifugal force generated by the high-speed airflow throws the droplets toward the chamber wall. The chamber wall is coated with a hydrophobic coating. After the droplets coalesce, they flow along the wall surface into the bottom collection tank. The collection tank of the gas-liquid separator body 1 is drained through the drain pipe 4, which can be achieved by opening the drain valve 5. The liquid level sensor detects the liquid level in the collection tank, thereby automatically controlling the drain valve to open. An adjustable guide plate is set at the inlet of the gas-liquid separator body 1, which automatically adjusts the cyclone intensity according to the fluid flow rate to optimize the separation efficiency. The angle of the guide plate is driven by a micro servo motor and dynamically adjusted by pressure feedback. The dry gas enters the pressure transmitter through the top outlet. This allows this utility model to separate micron-sized droplets by centrifugal force with a separation efficiency of over 99%, significantly reducing the transmitter failure rate. At the same time, automatic drainage reduces manual intervention, extends the maintenance cycle by more than 50%, and the volume is only 1 / 5 of that of a traditional settling tank, making it suitable for narrow pipe spaces and providing stable separation results.
