Description

防沼氣返流裝置Biogas backflow prevention device

本發明係與管道排水裝置有關，特別是指一種防沼氣返流裝置。The present invention relates to pipeline drainage devices, in particular to a biogas backflow prevention device.

按，台灣地處亞熱帶地區，夏、秋二季氣候相當酷熱，所以中央空調機、冷氣機的使用量很高，不論是窗型冷氣機、分離式冷氣機或是中央空調系統，都是利用吹出的冷風降低室內溫度，讓室內形成最舒適之涼爽環境，但上述機器運作時會產生凝結水，為了避免凝結水滴的到處都是，一般都是連接一排水管道先將凝結水排入一暫存裝置，再排放到屋外的水溝或下水道，由於水溝或下水道中也有汙水排入，因此會有微量的沼氣，而沼氣就會順著排水管道回流到中央空調機、冷氣機中的送風裝置，一方面，會導致送風裝置中的銅管被腐蝕穿透，造成冷媒外洩、冷氣不涼，之後更將導致冷氣機氣故障，二方面，沼氣進入屋內，會造成屋內瀰漫沼氣的臭味，影響居住品質。According to reports, Taiwan is located in a subtropical area, and the climate is very hot in summer and autumn, so the usage of central air conditioners and air conditioners is very high. Whether it is a window air conditioner, a split air conditioner or a central air conditioning system, all use blowing The cold air lowers the indoor temperature and creates the most comfortable and cool environment indoors. However, the above-mentioned machines will produce condensation water when operating. In order to avoid condensation water droplets everywhere, a drainage pipe is usually connected to drain the condensation water into a temporary storage. device, and then discharge it to the ditch or sewer outside the house. Since sewage is also discharged into the ditch or sewer, there will be a trace amount of biogas, and the biogas will flow back along the drainage pipe to the air supply in the central air conditioner and air conditioner. On the one hand, it will cause the copper pipes in the air supply device to be corroded and penetrated, causing the refrigerant to leak out and the air conditioner will not be cool, which will later cause the air conditioner to malfunction. On the other hand, if biogas enters the house, it will cause the house to be filled with biogas. The odor affects the quality of living.

The first water pipe 200 is connected to an air conditioner. Drainage pipe (not shown), the second water pipe 300 extends into the ditch or sewer (not shown) outside the house; the anti-methane backflow device 100 includes: a body 10, a partition plate 20, and a sphere 30. A non-return flow channel 40, a check valve 50 and an upper cover 60.

該本體10設呈中空狀而具有一容室11，於該本體10一側具有一第一通孔12、一第一接管13，該第一接管13以該第一通孔12連通該容室11，該第一接管13且連接該第一水管200，於該本體10另一側具有一第二通孔14、一第二接管15，該第二接管15以該第二通孔14連通該容室11，該第二接管15且連接該第二水管300；又，於該本體10設置該第二接管15的一側往外凸出設有一第一導管16，該第二接管15的一側往外凸出設有一第二導管17。The body 10 is hollow and has a chamber 11. There is a first through hole 12 and a first pipe 13 on one side of the body 10. The first pipe 13 communicates with the chamber through the first through hole 12. 11. The first pipe 13 is connected to the first water pipe 200 and has a second through hole 14 and a second pipe 15 on the other side of the body 10. The second pipe 15 communicates with the second pipe 14 through the second through hole 14. In the chamber 11, the second pipe 15 is connected to the second water pipe 300; in addition, a first conduit 16 protrudes outward from the side of the body 10 on which the second pipe 15 is disposed. A second conduit 17 is provided protruding outward.

該分隔板20設置於該容室11內鄰近該第二接管15、且區隔出一作動空間21，該作動空間21連通該第二通孔14，該作動空間21並具有一第三通孔22連通該容室11。The partition plate 20 is disposed in the chamber 11 adjacent to the second pipe 15 and separates an actuating space 21. The actuating space 21 is connected to the second through hole 14. The actuating space 21 also has a third through hole. The hole 22 communicates with the chamber 11 .

該球體30放置於該作動空間21內，且以自重同時堵住該第三通孔22與該第二通孔14。The sphere 30 is placed in the action space 21 and simultaneously blocks the third through hole 22 and the second through hole 14 with its own weight.

該止逆流道40設置於該本體10外部，該止逆流道40具有一第一端41連通該作動空間21、一第二端42連通該第二接管15；該止逆流道40之該第一端41的設置位置高於該第二端42的設置位置，該本體10之該第一導管16伸設於該止逆流道40之該第一端41內部，該第二接管15之該第二導管17伸設於該止逆流道40之該第二端42內部。The anti-return flow channel 40 is provided outside the body 10 . The anti-return flow channel 40 has a first end 41 connected to the actuating space 21 and a second end 42 connected to the second connecting pipe 15 ; the first end of the anti-return flow channel 40 The end 41 is positioned higher than the second end 42 . The first conduit 16 of the body 10 extends inside the first end 41 of the anti-return flow channel 40 . The conduit 17 extends inside the second end 42 of the anti-return flow channel 40 .

該止回閥50設置於該止逆流道40之該第一端41、於該第一導管16內。The check valve 50 is disposed at the first end 41 of the anti-return flow channel 40 and in the first conduit 16 .

該上蓋60蓋設於該本體10且可封閉該容室11。The upper cover 60 covers the main body 10 and can seal the chamber 11 .

依據上述之本發明防沼氣返流裝置100，安裝於該第一水管200與一第二水管300之間，可使從冷氣機的排水管道排出的凝結水(圖中以↑表示)自該第一水管200流入該本體10中，經該第一接管13、該第一通孔12進入該容室11中暫存，當該容室11中暫存的凝結水的水位尚未達到該第三通孔22時，該球體30同時堵住該第三通孔22與該第二通孔14，能防止由該第二水管300回流的沼氣(圖中以⇧表示)朝該第一水管200的方向逆流，且，沼氣雖然可經該第二接管15穿過第二導管17進入該止逆流道40內，但是，設置於該止逆流道40該第一端41內之該止回閥50是單向流通的結構，可以阻擋沼氣進入該作動空間21。According to the above-described biogas backflow prevention device 100 of the present invention, it is installed between the first water pipe 200 and a second water pipe 300, so that the condensed water (indicated by ↑ in the figure) discharged from the drainage pipe of the air conditioner can be discharged from the third water pipe 200. A water pipe 200 flows into the body 10 and enters the chamber 11 through the first pipe 13 and the first through hole 12 for temporary storage. When the water level of the temporarily stored condensate in the chamber 11 has not reached the third through hole, When the hole 22 is opened, the sphere 30 blocks the third through hole 22 and the second through hole 14 at the same time, which can prevent the biogas (indicated by ⇧ in the figure) flowing back from the second water pipe 300 toward the first water pipe 200 Counterflow, and although the biogas can enter the anti-return flow channel 40 through the second connecting pipe 15 and the second conduit 17, the check valve 50 provided in the first end 41 of the anti-return flow channel 40 is a single The structure of directional circulation can prevent biogas from entering the action space 21.

如第2圖所示，當排到該容室11中暫存的凝結水增加，凝結水的水位逐漸升高時，該球體30受到凝結水的浮力作用向上浮起，並離開該第三通孔22，使該容室11與該第二水管300呈導通狀態，凝結水即可自該容室11、經該第三通孔22、該第二通孔14、該第二接管15，再朝該第二水管300導往外屋外的水溝或下水道排出。As shown in Figure 2, when the amount of temporarily stored condensed water discharged into the chamber 11 increases and the level of the condensed water gradually rises, the sphere 30 floats upward due to the buoyancy of the condensed water and leaves the third passage. The hole 22 makes the chamber 11 and the second water pipe 300 in a conductive state, and the condensed water can flow from the chamber 11 through the third through hole 22, the second through hole 14, the second connecting pipe 15, and then The second water pipe 300 is directed to a ditch or sewer outside the outhouse for discharge.

而，當該球體30向上浮起脫離該第三通孔22，使該凝結水往該第二接管15的方向排出時，在該作動空間21內的沼氣可以從該第一導管16通過該止回閥50、往該止逆流道40之該第二端42方向導出，並從該第二導管17排至該第二接管15，最後再從該第二水管300排往外，使沼氣完全被隔絕在本發明防沼氣返流裝置100之該本體10以外，如此，可以抑制沼氣回流，達到完全隔離沼氣之效果，可以確保銅管不被腐蝕，能延長冷氣機的使用壽命，以及確保居家空氣品質良好，達成預期的創作目的。However, when the ball 30 floats upward and away from the third through hole 22 so that the condensed water is discharged in the direction of the second pipe 15, the biogas in the action space 21 can pass through the stopper from the first conduit 16. The return valve 50 is led out in the direction of the second end 42 of the anti-reverse flow channel 40, and is discharged from the second conduit 17 to the second connecting pipe 15, and finally discharged from the second water pipe 300 to the outside, so that the biogas is completely isolated. In addition to the main body 10 of the biogas backflow prevention device 100 of the present invention, in this way, the backflow of biogas can be suppressed, the effect of completely isolating biogas can be achieved, the copper pipe can be ensured not to be corroded, the service life of the air conditioner can be extended, and the air quality in the home can be ensured. Good, achieving the expected creative purpose.
