Description

Technical Field

[0001] The utility model relates to the field of condensate drainers, in particular to a condensate drainer used on a gas transmission pipeline. Background Art

[0002] During the transportation of various gases, the water vapor carried in the gas will condense in the pipeline to form condensed water. If the condensed water is not discharged in time, it will cause obstacles to gas transportation and practical use. Especially in the process of gas transportation, if the condensed water is not discharged during transportation, it will cause serious obstruction of gas and make gas unable to be used normally;

[0003] In the prior art, there are various types of drainers for draining condensed water from gas transportation pipelines. Among them, the condensed water drainers for gas pipelines have special requirements for drainers. Due to the special nature of gas, if gas leaks during the drainage process, it will cause serious safety problems. Therefore, the existing condensed water drainers for gas pipelines on the market need to have anti-leakage functions.

[0004] Among them, the Chinese patent with patent number ZL202322253275.3 discloses: "An anti-leakage gas drainer, including a drainer body and an anti-leakage mechanism, wherein the anti-leakage mechanism is installed on the left side of the drainer body. The anti-leakage gas drainer can discharge the condensed water in the gas pipeline through the cooperation of the drainer body and the anti-leakage mechanism. Through the cooperation of the filter screen and the baffle plate processed inside the top of the drain pipe, the condensed water in the cylinder can be filtered, and the ash in the condensed water can be filtered out to prevent it from clogging the drain pipe. Through the work of the alarm processed on the top of the shell, when there is gas overflow, the alarm can be triggered to alarm the outside world to remind the staff to inspect. When the inside of the cylinder needs to be cleaned, the condensed water can be heated to 80 to 90 degrees through the work of the heating wire, so that the tar is melted, and the ash in the condensed water and the melted tar are conveniently discharged from the sewage outlet, so as to facilitate the cleaning of the cylinder."

[0005] However, including the solutions described in the above-mentioned patents, there is a problem with this type of gas pipeline condensate drainers with anti-leakage function in the prior art, that is, sensors are set at the overflow ports of these condensate drainers to sense whether there is gas discharged through the overflow ports so as to determine whether the gas breaks through the water seal of the drainer and causes gas leakage. In fact, when the sensor senses the gas leakage, the leakage has already occurred, resulting in insufficient anti-leakage performance of the existing condensate drainers. Summary of the invention

[0006] In order to overcome the deficiency of the prior art that the anti-leakage performance of the condensate drainer for gas pipeline is not good enough, the utility model provides a condensate drainer applied to the gas transmission pipeline.

[0007] The utility model solves the technical problem by providing a condensate drainer applied to a gas transmission pipeline, comprising:

[0008] Support frame;

[0009] A water seal tank body is arranged on the upper side of the support frame, wherein the interior of the water seal tank body is divided into a plurality of chambers by partitions, including a high-pressure chamber, an intermediate chamber and a low-pressure chamber;

[0010] A water inlet pipe is passed through the water seal tank body, the water inlet end of the water inlet pipe is located above the water seal tank body, and the water outlet end of the water inlet pipe is located in the water seal tank body and close to the bottom of the water seal tank body;

[0011] An overflow pipe is provided on the water seal tank body and communicated with the low-pressure chamber;

[0012] The high-pressure chamber and the intermediate chamber, and the intermediate chamber and the low-pressure chamber are connected via connecting pipes, the upper end of the connecting pipes is arranged near the top of the water seal tank, and the lower end of the connecting pipes is arranged near the bottom of the water seal tank;

[0013] Also included are:

[0014] An electric control box is also arranged on the upper side of the support frame, and an alarm light is also connected to the top of the electric control box;

[0015] A solenoid valve connected to the water inlet end of the water inlet pipe, the solenoid valve being electrically connected to the electric control box for communication;

[0016] A liquid level monitoring mechanism, comprising three liquid level sensors and a liquid level switch electrically connected to an electric control box; the liquid level sensors and the liquid level switch are both arranged through the top of a water-sealed tank body; wherein the liquid level sensors are arranged one by one above a high-pressure chamber, an intermediate chamber and a low-pressure chamber; the liquid level switch is arranged above the intermediate chamber, and the liquid level switch also comprises a float located in the intermediate chamber, and the height of the float is lower than the height of the upper end of a connecting pipe.

[0017] Furthermore, the high-pressure chamber, the intermediate chamber and the low-pressure chamber are all filled with water, the water level in the high-pressure chamber is higher than the height of the water outlet end of the water inlet pipe, and the water level in the intermediate chamber and the low-pressure chamber are both higher than the height of the lower end of the connecting pipe, thereby achieving a water seal for the three chambers.

[0018] Furthermore, the three liquid level sensors are used to control the alarm light. When the three liquid level sensors sense that the water level in the water seal in the corresponding chamber rises suddenly, the liquid level sensors control the alarm light to sound an alarm. The liquid level switch is used to control the solenoid valve. When the water level in the low-pressure chamber exceeds the float height of the liquid level switch, the liquid level switch controls the solenoid valve to close, thereby blocking the passage at the water inlet pipe.

[0019] Furthermore, a temperature monitoring mechanism is included, the temperature monitoring mechanism includes a temperature measuring instrument installed on the water seal tank body, the temperature measuring instrument is electrically connected to the electric control box, and the probe of the temperature measuring instrument is located in the low-pressure chamber;

[0020] A steam pipe is also provided on the top of the water seal tank body, and the steam pipe extends into the low-pressure chamber.

[0021] Furthermore, the temperature measuring instrument is also used to control the alarm light. When the temperature measuring instrument senses that the water temperature in the low-pressure chamber is too low, the temperature measuring instrument can control the alarm light to sound an alarm to remind the staff to turn on the steam source, thereby injecting steam into the water seal chamber through the steam pipe to increase the temperature.

[0022] Furthermore, three observation windows are provided on the water seal tank body, and the observation windows are arranged on the side walls of the high-pressure chamber, the intermediate chamber and the low-pressure chamber in a one-to-one correspondence, and the height of the dirt accumulated at the bottom of each chamber can be observed through the observation windows;

[0023] In addition, hand holes are arranged on the side walls of the high-pressure chamber, the intermediate chamber and the low-pressure chamber near the bottom.

[0024] Furthermore, sewage pipes are provided on the side walls of the high-pressure chamber, the intermediate chamber and the low-pressure chamber near the bottom.

[0025] Furthermore, when it is observed through the observation window that the stains in each chamber are too high, the water in each chamber can be drained through the drainage pipe first, and then the stains at the bottom of the chamber can be taken out through the hand hole.

[0026] Furthermore, a water supply pipe is provided on the top of the water seal tank body, and the water supply pipe is connected to the low-pressure chamber.

[0027] Furthermore, a plurality of universal wheels are connected to the bottom of the support frame, and push handles are provided at both ends of the upper side of the support frame.

[0028] Furthermore, the universal wheel can also be rotatably connected to a stop plate, and the stop rod can be rotated to move closer to or away from the universal wheel;

[0029] When the anti-rotation plate is close to the universal wheel, the anti-rotation plate can act on the universal wheel to prevent the universal wheel from rotating;

[0030] When the anti-rotation plate is away from the universal wheel, the effect of the anti-rotation plate on the universal wheel is released, and the universal wheel can rotate.

[0031] Furthermore, a display screen is provided on the front of the electric control box, and a plurality of control buttons are provided below the display screen.

[0032] Condensate discharge method and leakage prevention method of the utility model:

[0033] When the water level in each chamber of the water seal tank is normal, the solenoid valve on the water inlet pipe is in a normally open state, and the condensed water in the gas pipeline can enter the high-pressure chamber of the water seal tank through the water inlet pipe, and some gas will also escape to the water seal tank through the water inlet pipe, but will be blocked by the water seal in the high-pressure chamber and cannot enter the high-pressure chamber through the water inlet pipe;

[0034] When the air pressure in the gas pipeline fluctuates and causes a sudden increase in air pressure, the gas in the water inlet pipe may break through the water seal in the high-pressure chamber and then move to the middle chamber through the connecting pipe. However, since a water seal is also provided in the middle chamber, the gas will be blocked again. However, if the water seal in the middle chamber is also broken through, causing the gas to flow to the low-pressure chamber, and when the gas breaks through the water seal in the low-pressure chamber, the water level in the low-pressure chamber will rise suddenly. When the water level exceeds the float height of the liquid level switch, the liquid level switch can close the solenoid valve through the electrical control box to block condensed water and gas from continuing to enter the water seal tank through the water inlet pipe, thereby effectively and timely preventing the air pressure in the water seal tank from continuing to rise, and ensuring that the gas will not be discharged to the outside through the overflow pipe. The subsequent liquid level sensor senses the changes in the liquid level of each chamber, and can also control the alarm light to sound an alarm to remind the staff to handle and maintain the water seal tank in time.

[0035] The beneficial effects of the utility model are:

[0036] 1. The liquid level monitoring mechanism not only has a liquid level sensor to sense the water level of each chamber, but also has a liquid level switch to quickly respond to the change of the water level in the low-pressure chamber, so as to close the solenoid valve on the water inlet pipe in time, so that the air pressure in the surface water seal tank continues to rise and cause gas leakage, thereby realizing the response before the gas leaks, and truly achieving the anti-leakage function;

[0037] 2. A temperature monitoring mechanism is also provided. When the drainer is used in some low-temperature areas, the temperature change in the water seal tank can be monitored in real time by the temperature monitoring mechanism. When the temperature is too low, an alarm can be issued in time, so that the staff can input steam into the water seal tank through the steam pipe to maintain the temperature in the water seal tank;

[0038] 3. The amount of dirt accumulated at the bottom of each chamber can also be checked through the observation window, so that the staff can clean and maintain the water seal tank in time;

[0039] 4. A universal wheel is provided at the bottom of the support frame to realize the movement of the entire drainer, and a stop plate is also provided on the universal wheel to fix the position of the drainer after it is moved into place, making the entire installation and setting process of the drainer more convenient.

[0066] Condensate discharge method and leakage prevention method of this embodiment:

[0067] When the water level in each chamber of the water seal tank 2 is normal, the solenoid valve 12 on the water inlet pipe 7 is in a normally open state, and the condensed water in the gas pipeline can enter the high-pressure chamber 4 of the water seal tank 2 through the water inlet pipe 7, and part of the gas will also escape to the water seal tank 2 through the water inlet pipe 7, but will be blocked by the water seal in the high-pressure chamber 4 and cannot enter the high-pressure chamber 4 through the water inlet pipe 7;

[0068] When the air pressure in the gas pipeline fluctuates and causes a sudden increase in air pressure, the gas in the water inlet pipe 7 may break through the water seal in the high-pressure chamber 4 and then move to the intermediate chamber 5 through the connecting pipe 9. However, since a water seal is also provided in the intermediate chamber 5, the gas will be blocked again. However, if the water seal in the intermediate chamber 5 is also broken through, causing the gas to flow to the low-pressure chamber 6, and when the gas breaks through the water seal in the low-pressure chamber 6, the water level in the low-pressure chamber 6 will rise suddenly. When the water level exceeds the height of the float 15 of the liquid level switch 14, the liquid level switch 14 can close the solenoid valve 12 through the electrical control box 10 to block condensed water and gas from continuing to enter the water seal tank body 2 through the water inlet pipe 7, thereby effectively and timely preventing the air pressure in the water seal tank body 2 from continuing to rise, and ensuring that the gas will not be discharged to the outside through the overflow pipe 8. The subsequent liquid level sensor 13 senses the changes in the liquid level of each chamber, and can also control the alarm light 11 to sound an alarm to remind the staff to handle and maintain the water seal tank body 2 in time.

[0069] The advantage of this embodiment is that: while the liquid level height in the water seal tank is monitored by the liquid level monitoring mechanism, a quick response can be made when the liquid level suddenly rises, so as to ensure that the gas does not leak through the water seal tank.
