DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] In the embodiment, Figure 1-4 A biogas connecting pipe is provided. The utility model comprises a first connecting pipe 1, a second connecting pipe 2 is fixedly connected to the right side of the first connecting pipe 1, a refrigerator 3 is fixedly connected to the top of the second connecting pipe 2, condensers 4 are fixedly connected to the left and right sides of the refrigerator 3, the bottoms of the two condensers 4 are fixedly connected to refrigeration rings 5 fixedly connected to the second connecting pipe 2, a drainage box 6 is fixedly connected to the bottom of the second connecting pipe 2, a drainage port 7 is fixedly connected to the bottom of the drainage box 6, a water retaining device 8 is movably connected to the inside of the drainage port 7, a filter 9 is fixedly connected to the right side of the second connecting pipe 2, a third connecting pipe 10 is fixedly connected to the right side of the filter 9, and an air pump 11 is fixedly connected to the inside of the third connecting pipe 10.
[0028] The diameter of the first connecting tube 1 is greater than the diameter of the second connecting tube 2 , and a sealing gasket is connected between the first connecting tube 1 and the second connecting tube 2 .
[0029] The gas enters the second connecting tube 2 from the first connecting tube 1 . As the space becomes smaller, the gas in the second connecting tube 2 is more easily affected by the refrigeration ring 5 .
[0030] The left and right sides of the second connecting pipe 2 are both arranged to be inclined toward the middle, and the thickness of the pipe connecting portion of the second connecting pipe 2 and the refrigeration ring 5 is thinner than the pipe portion not connected to the refrigeration ring 5 .
[0031] The thin pipe makes the refrigeration ring 5 have a better refrigeration effect, and the condensed water vapor turns into water and flows to the drain port 7 through the inclined pipe.
[0032] Among them, the water retaining device 8 includes a drain pipe 81 movably connected to the inside of the drain outlet 7, a fixed plate 82 is fixed to the top of the drain pipe 81, the bottom of the fixed plate 82 is fixedly connected to a water stop pad 83 fixedly connected to the outside of the drain pipe 81, the top of the fixed plate 82 is fixedly connected to a weight block 84, and the top of the weight block 84 is fixedly connected to an air bag 85.
[0033] When the condensed water accumulates to a level exceeding that of the airbag 85 , the airbag 85 will slowly float the water retaining device 8 as the water level rises, thereby allowing the water to flow out from below.
[0034] Among them, a plurality of through holes are opened on the inner side of the drainage pipe 81 , and the buoyancy of the air bag 85 in water is greater than the gravity of the entire water retaining device 8 .
[0035] After the water retaining device 8 floats up, the water is discharged from the through hole opened in the drain pipe 81. After the water is discharged, the water retaining device 8 will fall down due to gravity and block the drain outlet again.
[0036] The filter 9 includes a filter screen 91 disposed on the left side of the filter 9 , activated carbon 92 is disposed on the right side of the filter screen 91 , and ferrite 93 is disposed on the right side of the activated carbon 92 .
[0037] The passing biogas is further dehydrated, desulfurized and particle-removed.
[0038] Working principle:
[0039] The biogas first enters the second connecting pipe 2 from the first connecting pipe 1, and the refrigeration ring 5 is used by the refrigerator 3 to cool the second connecting pipe 2 so that the water vapor in the biogas condenses into water, and the water flows into the drainage box 6. When the water in the drainage box 6 accumulates to a certain level, the water retaining device 8 floats upward to drain the water, falls down after draining the water, and then blocks the drainage port 7 again. The biogas enters the filter 9 through the second connecting pipe 2, and is output through the third connecting pipe 10 and the air pump 11.
