With the continuous advancement of industrial technology and increasingly stringent environmental requirements, higher demands are being placed on the efficiency, stability, energy consumption, and ease of maintenance of gas-liquid separation equipment.

[0003] Heat exchangers are indispensable equipment for heat exchange and transfer in chemical production processes. In industries such as petroleum, chemical, light industry, pharmaceuticals, and energy, they are often used to heat low-temperature fluids or cool high-temperature fluids, vaporize liquids into steam or condense steam into liquids. Domestic market demand exhibits the following characteristics: higher requirements for product quality, such as environmentally friendly and energy-saving products being the focus of development; a demand for improved product cost-effectiveness; a strong trend towards personalized and diversified products; increasing attention to branded products; and a preference for products from large enterprises or enterprise groups in large engineering projects.

[0004] Traditional gas-liquid separation equipment often struggles to achieve multi-stage series or parallel operation, making it difficult to meet the demands of large-scale, continuous production. Furthermore, the lack of an effective online monitoring and control system makes it difficult to monitor the equipment's operating status in real time, hindering adjustments and optimizations, and impacting production efficiency and product quality.

[0005] Therefore, this application provides a multi-stage plate gas-liquid separation device to solve the problems mentioned in the background art. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a multi-stage plate gas-liquid separator, which can more effectively handle tiny droplets, significantly improve separation efficiency, ensure the purity of the separated gas and the recovery rate of the liquid, and provide high-quality raw materials or products for subsequent processes.

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A multi-stage plate-type gas-liquid separator includes a main body with an air inlet at the left end and an air outlet at the right end. Three gas-liquid separators are installed inside the main body, each including an inlet pipe and an outlet pipe. Multiple plate heat exchanger plates, evenly distributed vertically, are installed between the inlet and outlet pipes. A liquid storage hopper is located at the outer end of each plate heat exchanger plate, and a drain pipe is installed at the outer end of the liquid storage hopper. The drain pipe penetrates the bottom of the main body, enabling more effective processing of tiny droplets, significantly improving separation efficiency, ensuring the purity of the separated gas and the recovery rate of the liquid, and providing high-quality raw materials or products for subsequent processes.

[0009] As a further improvement of this utility model, an inspection door is embedded in the outer end of the main body of the equipment, and an observation window is fixedly connected inside the inspection door. Technicians can observe the working condition inside the equipment through the observation window. If any abnormality is found, the inspection door can be opened for inspection and maintenance.

[0010] As a further improvement of this utility model, flanges are installed at the inlet, outlet, and outlet pipes. The flanges facilitate the connection and disassembly of the pipes and make the installation and commissioning of the equipment easier.

[0011] As a further embodiment of this utility model: valves, water pumps, temperature sensors, and flow sensors are installed on the inlet pipes; valves and temperature sensors are installed on the outlet pipes; and valves are installed on the drain pipes.

[0012] As a further improvement of this utility model: a pressure sensor is installed at the left end of the liquid storage tank. The liquid formed after heat exchange flows into the liquid storage tank, and the pressure sensor monitors the pressure in the liquid storage tank in real time. When the liquid accumulates to a certain amount, it is discharged from the main body of the equipment through the drain pipe.

[0013] As a further improvement of this invention, an electrical control cabinet is installed on the upper part of the main body of the equipment. The electrical control cabinet is electrically connected to a temperature sensor, a flow sensor, and a pressure sensor. By setting up the electrical control cabinet, temperature, flow, and pressure data are collected by the temperature sensor, flow sensor, and pressure sensor, processed by the electrical control cabinet, and then output for control. Beneficial effects

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. This device uses plate heat exchanger plates as the core separation element. By utilizing the different temperature and pressure environments formed between the plates by circulating water, and based on the principle of different liquid boiling point differences, it achieves efficient gas-liquid separation of gaseous substances. Compared with traditional gas-liquid separation technology, this invention can more effectively handle tiny droplets, significantly improve separation efficiency, ensure the purity of the separated gas and the recovery rate of the liquid, and provide high-quality raw materials or products for subsequent processes.

[0016] 2. The device is equipped with an advanced electrical control cabinet system, which is electrically connected to temperature sensors, flow sensors, and pressure sensors. This enables real-time monitoring and precise control of the circulating water temperature, flow rate, and pressure in the storage tank. The application of high-precision sensors such as temperature sensors, flow sensors, and pressure sensors makes the equipment's operating status readily apparent. Technicians can adjust operating parameters in a timely manner based on the monitoring data to ensure that the device is always in optimal working condition. This high degree of automation not only improves production efficiency but also greatly reduces the risk of human error, ensuring production safety.

[0017] 3. The embedded maintenance door of this device ensures the airtightness of the main body of the equipment and facilitates technicians to quickly open it for internal maintenance when needed. The observation window allows technicians to directly observe the internal working condition of the equipment without opening the maintenance door, and promptly identify and deal with potential problems. In addition, flanges are installed at the inlet, outlet and outlet pipes to facilitate quick connection and disassembly of the pipes, which greatly shortens the time for equipment installation, commissioning and maintenance, and reduces labor intensity and costs.

[0025] Example

[0026] Please see Figures 1-2 A multi-stage plate gas-liquid separator includes a main body 1, an air inlet 12 at the left end of the main body 1, an air outlet 13 at the right end of the main body 1, and three gas-liquid separators installed inside the main body 1. Each gas-liquid separator includes an inlet pipe 7 and an outlet pipe 11. Multiple plate heat exchanger plates 6 are evenly distributed vertically between the inlet pipe 7 and the outlet pipe 11. A liquid storage hopper 9 is provided at the outer end of the plate heat exchanger plates 6, and a drain pipe 10 is installed at the outer end of the liquid storage hopper 9. The drain pipe 10 penetrates the bottom end of the main body 1, which can more effectively handle tiny droplets, significantly improve separation efficiency, ensure the purity of the separated gas and the recovery rate of the liquid, and provide high-quality raw materials or products for subsequent processes.

[0027] Water enters the gas-liquid separator through the inlet pipe 7, passes through the plate heat exchanger plates 6, and is discharged through the outlet pipe 11. During the circulation process, the water pump 3 provides power, the valve 2 controls the flow rate, and the temperature sensor 4 and flow sensor 5 monitor the water temperature and flow rate in real time, transmitting the data to the electrical control cabinet 17 for technical personnel to control and adjust.

[0028] Please see Figure 1 The main body 1 of the equipment has an inspection door 15 embedded at its outer end. An observation window 16 is fixedly connected inside the inspection door 15, allowing technicians to observe the internal workings of the equipment. If any abnormalities are found, the inspection door 15 can be opened for inspection and maintenance. An electrical control cabinet 17 is installed on the upper part of the main body 1. The electrical control cabinet 17 is electrically connected to temperature sensor 4, flow sensor 5, and pressure sensor 8. Through the electrical control cabinet 17, temperature, flow, and pressure data are collected by the temperature sensor 4, flow sensor 5, and pressure sensor 8, processed, and then output for control. Flanges 14 are installed at the inlet pipe 7, drain pipe 10, and outlet pipe 11. The flanges 14 facilitate the connection and disassembly of the pipes, making the installation and commissioning of the equipment easier.

[0029] Please see Figures 1-2 Each inlet pipe 7 is equipped with a valve 2, a water pump 3, a temperature sensor 4, and a flow sensor 5. Each outlet pipe 11 is equipped with a valve 2 and a temperature sensor 4. Each drain pipe 10 is equipped with a valve 2. A pressure sensor 8 is installed at the left end of the storage hopper 9. The liquid formed after heat exchange flows into the storage hopper 9, and the pressure sensor 8 monitors the pressure inside the storage hopper 9 in real time. When the liquid accumulates to a certain amount, it is discharged from the main body 1 of the equipment through the drain pipe 10.

[0030] Working principle: When technicians use this device, gaseous substances enter the main body 1 of the equipment through the air inlet 12 and exchange heat with the plate heat exchanger plates 6 in the gas-liquid separation device. In the gas-liquid separation device, water enters from the water inlet pipe 7, passes through the plate heat exchanger plates 6, and is discharged from the water outlet pipe 11. The circulating water creates different temperatures and pressures in the plate heat exchanger. Taking advantage of the different boiling points of different liquids, the gaseous substances are separated into gas and liquid. The liquid formed after heat exchange flows into the liquid storage hopper 9 and is discharged from the main body 1 of the equipment through the drain pipe 10. Compared with the prior art, this utility model can more effectively handle tiny droplets, significantly improve separation efficiency, ensure the purity of the separated gas and the recovery rate of the liquid, and provide high-quality raw materials or products for subsequent processes.
