Description

Technical Field

[0001] This utility model relates to the field of drainage device technology, and in particular to a drainage device for a gas engine. Background Technology

[0002] When a gas turbine engine is running, the chemical reaction of its fuel (mainly methane) burning in the cylinder directly generates water vapor, and moisture from the air is also drawn in and participates in the combustion process. Some of this high-temperature water vapor is expelled with the exhaust gas, but some will seep into the crankcase or cool components (such as the intercooler) and condense into liquid water. If this water cannot be drained in time, it will mix with the engine oil to form an emulsion, severely weakening lubrication performance and causing corrosion and rust on internal engine metal parts. Therefore, a drainage device is needed to remove this liquid water to ensure stable engine operation and extend its service life.

[0003] Existing intercooler drainage structures are insufficient to meet the requirements of stable operation and convenient maintenance. Most existing intercoolers rely on gravity drainage or simple manual valve drainage, lacking a mechanism to trigger water accumulation. In humid or rainy weather, condensate will quickly accumulate in the exhaust pipe, easily leading to water retention. Furthermore, in low-temperature environments, condensate that is not drained in time is very likely to freeze and block the exhaust pipe. Therefore, we propose a gas engine drainage device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a gas engine drainage device.

[0007] Preferably, the drainage assembly includes a hollow float, two arc-shaped wire meshes are fixedly embedded in the outer wall of the vertical sleeve, and a rubber sealing ring is fixedly connected inside the vertical sleeve. The top of the rubber sealing ring has a groove, and the inner wall of the groove is in contact with the outer wall of the float. When the float is not floating, the internal channel of the vertical sleeve is sealed by the tight contact between the groove and the float, preventing gas from leaking from the vertical sleeve and the drain hole.

[0008] Preferably, the outer wall of the annular rubber gasket is pressed against the outer wall of the mating sleeve, and the annular rubber gasket can fill the gap after the threaded connection between the round sleeve and the mating sleeve, greatly improving the sealing performance at the connection between the two.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1-4 As shown, a gas engine drainage device is disclosed, comprising an intercooler body 1, with multiple heat dissipation fins fixedly connected to the outer wall of the intercooler body 1, and an intake pipe 2 fixedly connected to the outer wall of the intercooler body 1. The intake pipe 2 guides the high-temperature gas discharged from the gas engine into the interior of the intercooler body 1. An outlet pipe 3 is fixedly connected to the outer wall of the intercooler body 1, and a connecting sleeve 5 is fixedly connected to the outer wall of the outlet pipe 3. The connecting sleeve 5 enables stable connection between the outlet pipe 3 and the circular sleeve 6, providing a guiding channel for condensate to flow from the outlet pipe 3 into the circular sleeve 6.

[0022] The inner wall of the mating sleeve 5 is threaded with a round sleeve 6, and the outer wall of the round sleeve 6 is fixedly fitted with an annular rubber gasket 7. The outer wall of the annular rubber gasket 7 is pressed against the outer wall of the mating sleeve 5. The annular rubber gasket 7 can fill the gap after the round sleeve 6 and the mating sleeve 5 are threaded together, which greatly improves the sealing performance of the connection between the two, effectively prevents gas from leaking from the gap, and at the same time prevents external dust and impurities from entering the pipeline and contaminating the condensate.

[0023] The inner wall of the round sleeve 6 is threaded with an inner sleeve 8, and the bottom of the inner sleeve 8 is fixedly connected with a knurled knob 9. The knurled knob 9 is convenient for the operator to rotate to drive the inner sleeve 8 and the round sleeve 6 to be disassembled and assembled.

[0024] The outer wall of the knurled knob 9 is provided with a drain hole 10, which is the final outlet of the condensate drain device. It can promptly drain the condensate flowing down after the float ball 14 in the vertical sleeve 11 opens the drain channel. The inner wall of the knurled knob 9 is fixedly connected to the vertical sleeve 11, which is located inside the circular sleeve 6.

[0025] An assembly hole is provided on the outer wall of the exhaust pipe 3. An electric heating rod 4 is fixedly connected to the inner wall of the assembly hole. The assembly hole is sealed. The electric heating rod 4 adopts a low-power, small-range heating design. The heating process only targets a small amount of water in the pipe and will not change the composition, temperature or pressure of the gas. Therefore, it will not have a negative impact on the combustion efficiency of the gas entering the combustion chamber. It is also electrically connected to the battery through the existing cable.

[0026] The electric heating rod 4 can be powered on and heated in low-temperature weather, directly heating the condensate inside the vent pipe 3 to prevent the condensate from freezing and blocking the connection channel between the vent pipe 3 and the docking sleeve 5, ensuring that the condensate can flow smoothly into the docking sleeve 5 later.

[0027] The vertical sleeve 11 is equipped with a drainage component, which includes a hollow float 14. Two arc-shaped wire meshes 12 are fixedly embedded in the outer wall of the vertical sleeve 11. The two arc-shaped wire meshes 12 are made of stainless steel. When condensate flows from the inner sleeve 8 into the vertical sleeve 11, the two arc-shaped wire meshes 12 can filter metal debris and other impurities in the condensate, preventing impurities from entering the interior of the vertical sleeve 11 and clogging the groove of the rubber sealing ring 13 or jamming the float 14.

[0028] A rubber sealing ring 13 is fixedly connected inside the vertical sleeve 11. The top of the rubber sealing ring 13 has a groove. The inner wall of the groove is in contact with the outer wall of the float 14. The float 14 utilizes the buoyancy characteristics of the hollow structure. When the condensate in the vertical sleeve 11 accumulates to a certain amount, it will float up and break away from the groove of the rubber sealing ring 13 to open the drainage channel.

[0029] Working principle: The intercooler body 1 is connected to the pipeline of the existing gas engine. The heat dissipation fins on the outer wall of the intercooler body 1 help the high-temperature gas to be quickly cooled after entering the intercooler body 1 through the intake pipe 2. The water vapor in the gas condenses into condensate. Some of the condensate enters the outlet pipe 3 with the cooled gas. When the weather is cold, the outlet pipe 3 is heated by the electric heating rod 4 inside the outlet pipe to prevent the condensate from freezing and blocking the outlet pipe 3 and the connecting sleeve 5.

[0030] When the condensate in the vent pipe 3 accumulates to a certain amount, it will flow into the connecting sleeve 5. The annular rubber gasket 7 squeezes the connecting sleeve 5 to seal and prevent leakage. The condensate enters the inner sleeve 8 through the round sleeve 6, and then passes through two arc-shaped wire meshes 12 to filter impurities in the water. Subsequently, the condensate accumulates in the vertical sleeve 11, causing the hollow float ball 14 to float up and detach from the groove of the rubber sealing ring 13 inside the vertical sleeve 11, opening the drainage channel. The condensate flows down the inner wall of the vertical sleeve 11 and is finally discharged through the drainage hole 10 on the outer wall of the knurled knob 9, completing the drainage. If maintenance is required, the knurled knob 9 can be rotated to rotate the inner sleeve 8 and remove the vertical sleeve 11 from the round sleeve 6.

[0031] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to the electric heating rod 4 to facilitate the control of the overall operation.
