Description

Gas exhaust port for waste reclaimed land

The present invention provides a smooth discharge of the gas from the discharge pipe at the gas outlet where the discharge pipe is installed in the landfill so that the gas generated from the landfill can be discharged upward through the discharge pipe and diffused or incinerated into the atmosphere. It is to be blocked to prevent backfire into the discharge pipe during gas incineration.

In general, as a means of waste disposal, waste is piled up on large landfills, covered with landfill, and then left for years or decades to naturally decompose wastes in the ground. There was a risk of explosion and fire.

Therefore, the inventors of the landfill gas discharge pipe were developed by the present inventors to discharge the landfill gas into the atmosphere and diffuse or incinerate it into the atmosphere, thereby releasing the risk of harmful and explosive gas, The discharged gas flowed backward into the discharge pipe, and there was a risk of backfire during incineration.

In order to solve this problem, the present invention is configured to form a distribution guide part having an expansion guide part and an upper and lower exhaust guides in an exhaust path of a gas discharge port connected to the gas discharge pipe. When the discharged gas flows into the exhaust path in the reverse direction, it is blocked firstly by hitting the exhaust guide plates disposed at the upper and lower ends of the distribution guide part, and the second cutoff is a means of remaining gas in the expansion guide part. It is to prevent backfire.

The gas outlet 20 is connected to the upper side of the gas discharge pipe 10 having the gas inlet 11, and a plurality of blow holes 30 formed in the lower portion of the protective cover 31 through the exhaust passage 21 of the gas outlet 20. In exhausting the gas into the exhaust gas, the exhaust passage 21 forms an expansion guide part 22 in the lower part and flows in an annular space between the inner cylinder 26 and the outer cylinder 27 above the expansion guide part 22. The guide 23 is formed, but the exhaust guides 24 and 24 ′ are disposed on the upper and lower ends of the distribution guide 23, respectively, and the vent hole 28 is formed on the upper sidewall of the outer cylinder 27. The exhaust chamber 29 is provided with a plurality of blowing holes 30 on the outside.

The exhaust guides 24 and 24 ′ are arranged in a streamlined manner in which the distribution space becomes narrower from the lower portion of the distribution guide portion 23 to the upper portion thereof, so that the gas rises smoothly with the configuration in which the blocking space portion 25 is formed at one side. It is made to hit the blocking space 25 when the gas flows in the reverse direction.

When the gas discharge pipe 10 is installed in a landfill and various harmful gases or explosive gases generated in the process of decomposing waste are introduced into the discharge pipe 10 through the gas inlet 11, the gas discharge port 20 is provided. It is sent to the exhaust chamber 29 through the expansion guide part 22 and the distribution guide part 23 formed in the exhaust path 21 of the exhaust path 21 and is discharged through a plurality of blow holes 30 can be diffused or incinerated in the atmosphere Will be.

At this time, the circulation guide part 23 has an annular space formed between the inner cylinder 26 and the outer cylinder 27 so that the gas in the discharge pipe 10 is diffused and then sent to the exhaust chamber 29 to open the jet hole 30. Because it is discharged through the air, it can be spread evenly in the atmosphere, and during ignition, it is well burned because of uniform combustion.

In addition, when the gas pressure discharged from the discharge pipe 10 becomes weak and is not discharged from the exhaust chamber 29 to the blowout hole 30, but is going to be flowed back into the discharge pipe 10 through the exhaust path 21, the exhaust path 21 The first guide is made by hitting each of the blocking spaces 25 on one side of the exhaust guides 24 and 24 'formed at the upper and lower ends of the distribution guide part 23 of the distribution guide part 23. When it enters into the discharge pipe 10 through the exhaust pipe 10 and enters the expansion guide 22, the secondary block is diluted in the expansion guide 22 having a larger space than the exhaust passage 21 at the lower portion thereof.

That is, the gas discharge of the discharge pipe 10 through the exhaust passage 21 is made smoothly, and when the discharged gas flows in the reverse direction, 1 in the distribution guide 23 and the expansion guide 22 of the exhaust passage 21. The secondary blocking action prevents backfire into the discharge pipe 10 during the gas incineration process.

In this way, the gas outlet of the present invention is a gas discharge of the discharge pipe is made smoothly to be uniformly diffused or incinerated in the atmosphere and to prevent the reverse flow of the discharged gas back to the discharge pipe during gas incineration.
