Abstract
Description
Technical Field
[0001] This utility model relates to the field of water-cooled heat exchanger technology, and in particular to a water-cooled gas leak detector. Background Technology
[0002] Industrial gases, after being processed by compressors, experience a temperature increase. To meet specific industrial requirements, water-cooled heat exchangers are typically used for cooling, transferring heat from the high-temperature fluid to a cooling medium (usually water) to form water-cooled gas. Currently, leak detection for water-cooled gas primarily involves observing the presence of air bubbles in the circulating water return test chamber or sampling the gas through the drain sampling port. However, observing the circulating water return test chamber is only visually inspectable and cannot provide real-time monitoring of leaks. Furthermore, when the leak is small, sampling through the drain sampling port is difficult because the gas has already diffused into the air. Utility Model Content
[0003] The purpose of this utility model is to provide a water-cooled gas leak detector that is simple in structure and easy to operate, which can more intuitively observe whether the water-cooled water is leaking and can play a real-time monitoring role, making it convenient for operators to take corresponding maintenance measures.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A water-cooled gas leak detector includes a water-cooled heat exchanger, a gas detector, and a gas-liquid phase separator. The water-cooled heat exchanger is provided with an inlet pipe, an outlet pipe, a water inlet pipe, and a water outlet pipe. The water outlet pipe is provided with a drain outlet, which is connected to the liquid inlet of the gas-liquid phase separator via a drain outlet pipe. The gas detector is connected to the outlet of the gas-liquid phase separator. The gas-liquid phase separator is provided with a liquid outlet. A liquid outlet pipe is connected to the liquid outlet, and one end of the liquid outlet pipe extends into the interior of the gas-liquid phase separator and is connected to a downwardly bent gas seal elbow.
[0006] As a preferred embodiment of this utility model, the drain pipe is equipped with a drain valve.
[0007] As a preferred embodiment of this utility model, the gas outlet of the gas-liquid phase separator is connected to the gas detector via a connecting pipe.
[0008] As a preferred embodiment of this utility model, the connecting pipe is provided with a liquid buffer chamber.
[0009] As a preferred embodiment of this utility model, the gas detector is equipped with an alarm.
[0010] As a preferred embodiment of this utility model, the water-cooled heat exchanger is a shell-and-tube water-cooled heat exchanger.
[0011] The water-cooled gas leak detector provided by this utility model has the following advantages compared with the prior art:
[0012] In operation, water flows into the gas-liquid phase separator through the drain pipe from the inlet and out through the outlet pipe. Since one end of the outlet pipe extends into the gas-liquid phase separator and is connected to a downward-curving gas-sealing elbow, the water flow creates a water seal on the elbow as it enters the separator. This retains the water-cooled gas within the separator, preventing escape and allowing detection by a gas detector. Compared to existing methods of observation via a circulating water return test mirror or sampling through the drain pipe, this invention provides a more direct way to observe whether the water-cooled water is leaking and enables real-time monitoring. This facilitates appropriate maintenance by the operator, and the design is simple and easy to operate. Attached Figure Description

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0018] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," "right," "front," "rear," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. It should also be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.
[0019] like Figure 1 As shown, a preferred embodiment of this utility model provides a water-cooled gas leak detector, which includes a water-cooled heat exchanger 100, a gas detector 200, and a gas-liquid phase separator 300. The water-cooled heat exchanger 100 is provided with an inlet pipe 101, an outlet pipe 102, a water inlet pipe 103, and a water outlet pipe 104. The water outlet pipe 104 is provided with a drain outlet 105, which is connected to the liquid inlet of the gas-liquid phase separator 300 through a drain outlet pipe 106. The gas detector 200 is connected to the outlet of the gas-liquid phase separator 300. The gas-liquid phase separator 300 is provided with a liquid outlet. A liquid outlet pipe 301 is connected to the liquid outlet, and one end of the liquid outlet pipe 301 extends into the interior of the gas-liquid phase separator 300 and is connected to a downwardly bent gas seal elbow 302.
[0020] It should be noted that, in this embodiment, the water-cooled heat exchanger 100 is preferably a shell-and-tube type water-cooled heat exchanger.
[0021] According to the water-cooled gas leak detector of this utility model, water flows into the gas-liquid phase separator 300 through the drain pipe 106 and is discharged through the outlet pipe 301. Since one end of the outlet pipe 301 extends into the gas-liquid phase separator 300 and is connected to a downwardly bent gas-sealing elbow 302, the water can achieve a water seal effect on the gas-sealing elbow 302 when the water flows into the gas-liquid phase separator 300. Therefore, the water-cooled gas can be retained in the gas-liquid phase separator 300 to prevent the water-cooled gas from escaping and can be detected by the gas detector 200. Therefore, compared with the existing technology of observing through the circulating water return test glass or sampling through the drain sampling port, it can more intuitively observe whether the water-cooled water is leaking and can play a real-time monitoring role, which is convenient for the operator to take corresponding maintenance measures. The structure is simple and easy to operate.
[0022] For example, the drain pipe 106 is equipped with a drain valve 107, which allows the operator to easily control the flow rate of water entering the gas-liquid phase separator 300, making operation simple.
[0023] For example, the gas outlet of the gas-liquid phase separator 300 is connected to the gas detector 200 via a connecting pipe 303, and the connecting pipe 303 is provided with a liquid buffer chamber 304. Thus, the liquid buffer chamber 304 can buffer and retain the water flow, preventing damage to the gas detector 200 due to excessive flow rate in the initial stage when water flows out of the drain pipe 106.
[0024] For example, the gas detector 200 is equipped with an alarm. When the gas detector 200 detects a water-cooled gas leak, it can sound an alarm to alert the operator, thereby facilitating the operator to take appropriate maintenance measures.
[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
