Description

Technical Field

[0001] The utility model belongs to the field of gas drainers, in particular to a leakage-proof gas drainer without breakdown liquid alarm. Background Art

[0002] Large-diameter and long-distance pipelines are required to transport gas from its generation to its use point. Since blast furnace, coke oven and converter gas will produce a large amount of condensed water due to temperature changes during transportation, if it is not discharged in time, it will cause combustion interruptions, affect combustion effects or cause accidents. Therefore, a gas condensate drainer must be used.

[0003] However, existing gas drainers generally do not have pressure buffer components. In actual production conditions, the gas pressure may rise a lot instantly and then recover quickly. In this case, the gas drainer is easily punctured, causing a large amount of gas leakage and causing serious accidents. Utility Model Content

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0017] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0018] Combination Figure 1-4 As shown, the leak-proof and non-breakdown liquid alarm gas drainer comprises a tank body 1, wherein a plurality of cavities are arranged in the tank body, wherein one cavity is a high-pressure cavity, and the other cavities are low-pressure cavities, wherein a water collecting pipe 4 is arranged in the high-pressure cavity, and an inner drainage pipe 5 is arranged in each low-pressure cavity, wherein the inner drainage pipe 5 is connected to the previous cavity, and a drainage pipe 6 is connected to the bottom of the last low-pressure cavity, wherein the tank body 1 is also connected to an air inlet pipe 7, and is characterized in that: a buffer pipe 2 is connected between the air inlet pipe 7 and the water collecting pipe 4 through a flange, and the A buffer member 8 is provided in the buffer tube 2, and a liquid alarm assembly 9 is provided in the lower part of the high-pressure chamber. The buffer member 8 includes a pair of upper and lower orifice plates, wherein the upper orifice plate is marked as 81 and the lower orifice plate is marked as 811. A plurality of slot holes 82 are provided on the orifice plates, wherein the lower orifice plate 811 is fixedly installed, and a guide rod 83 is inserted from the top of the upper orifice plate 81, and the bottom of the guide rod 83 is fixed to the lower orifice plate. A spring 84 is provided on the guide rod 83 between the two orifice plates, and a guide sleeve 85 is provided on the top of the guide rod 83.

[0019] As we all know, large-diameter and long-distance pipelines are required to transport gas from its generation to its use point. Since blast furnace, coke oven and converter gas will produce a large amount of condensed water due to temperature changes during transportation, the condensed water can be discharged through this gas drainer, thereby ensuring its combustion effect and avoiding accidents.

[0020] In the embodiment, the air inlet pipe is connected to a gas main (not shown in the figure), and a switch valve 10 is provided on the air inlet pipe 7. An explosion-proof device 12 is installed on the drain pipe 6, and the drain pipe and the explosion-proof device constitute an overflow device.

[0021] When working, the switch valve is opened, and sealing water is filled in each cavity of the tank body. The gas enters the water collecting pipe from the switch valve and reaches the high-pressure cavity in the cylinder body. Under normal circumstances, the sealing water in each cavity is full. Since the density of gas is smaller than that of water, water and gas separation is achieved, thereby achieving the effect of gas blocking and drainage. The separated condensed water reaches each low-pressure chamber through the drainage pipe in turn, and finally flows into the drainage pipe and is discharged through the explosion-proof device.

[0022] When production conditions change and the gas pressure rises a lot instantly, the buffer can be used to provide corresponding buffering to avoid the pressure in the high-pressure chamber increasing instantly, causing the gas drainer to be punctured, resulting in a large amount of gas leakage and causing serious accidents.

[0023] Specifically, when the gas pressure increases instantly, the gas can only enter the water collecting pipe through the slots on the orifice plate. At this time, the gas with increased pressure will squeeze the upper orifice plate, and the upper orifice plate moves toward the lower orifice plate along the guide rod. The spring is gradually compressed, playing a buffering role until the gas pressure returns to a stable state. When the spring recovers its deformation, the upper orifice plate is reset under the action of the spring. The guide sleeve plays the role of limiting the upper orifice plate.

[0024] The buffer pipe is connected between the air inlet pipe 7 and the water collecting pipe 4 through a flange, which is convenient for later disassembly and replacement of the entire buffer pipe.

[0025] As a preferred structure, Figure 1 , Figure 3 , Figure 4 The liquid alarm assembly 9 includes a base 91 mounted on the side wall of the tank body, the outer wall of the base 91 is provided with a wiring port 92, a circular groove 93 is opened at the central axis of the base 91, a ferrule 94 is formed in the circular groove, a sensor 95 is inserted and sealed in the ferrule 94, and the sensor 95 is electrically connected to the wiring port 92. The alarm is connected to the wiring port through wires.

[0026] When the water level in the high pressure chamber is abnormal, such as when the water level is low, the sensor senses and transmits the signal to the alarm, which then sends an alarm to alert people, thereby further improving the safety performance of the gas drainer.

[0027] In this structure, the sensor is inserted into and sealed to the ferrule for installation. The ferrule serves to install and protect the sensor.

[0028] At the same time, a shallow groove is opened in the top of the clamping sleeve 94, and a clamping ring 13 is inserted into the shallow groove, and the clamping ring 13 presses the sensor 95. When the sensor is installed in the clamping sleeve, the clamping ring is inserted into the shallow groove as required, and the clamping ring presses the sensor. Under the action of the clamping ring, the sensor is installed more stably.

[0029] The upper part of the high pressure chamber side wall is also provided with a liquid level gauge 14. By providing the liquid level gauge in the high pressure chamber, the liquid level in the high pressure chamber is monitored in real time by the liquid level gauge, so that relevant staff can understand the specific liquid level in the high pressure chamber at any time through the liquid level gauge.

[0030] In addition, if Figure 1 The top of the high-pressure chamber of the drainer is also connected to a water replenishment device, which includes a check valve 15 and a water inlet valve 16. The top of each chamber is also connected to an exhaust valve 17. When water replenishment is needed, the water inlet valve is opened to replenish water, and the exhaust valve is opened to exhaust air. After the water replenishment is completed, the water inlet valve and the exhaust valve are closed.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
