Description

Technical Field

[0001] The utility model relates to the technical field of combustion torches, in particular to an internal combustion type biogas torch. Background Art

[0002] Biogas is a combustible gas formed by the decomposition and fermentation of organic matter by microorganisms under anaerobic conditions. Its main components are methane, nitrogen and carbon dioxide. Under normal circumstances, the methane content in biogas is 45% to 65%, and the carbon dioxide is 20% to 30% and a small amount of impurities. It is a very harmful greenhouse gas that pollutes the atmospheric environment. A large amount of biogas and chemical tail gas emissions will lead to an increase in atmospheric temperature and severe climate, causing huge economic losses. Therefore, methane and other waste gases must be burned before they can be discharged. With the country's emphasis on environmental protection requirements and the improvement of national environmental awareness, a large number of domestic enterprises have begun to produce and treat the tail gas and sewage generated in the production process at the same time. For example, the biogas generated by petrochemical, chemical tail gas, sewage treatment, and garbage treatment is discharged into the air after being treated by combustion, which greatly improves the environment.

[0003] The utility model with authorization announcement number CN216693572U provides an internal combustion biogas incineration torch with high-efficiency combustion. By setting a coil, when the biogas passes through the coil, the cold air in the coil exchanges heat with the biogas, so that the water vapor in the biogas condenses and then falls into the water tank. The water vapor in the biogas can be filtered, thereby improving the efficiency of biogas combustion.

[0004] However, in the above patent, since the outer wall of the inner tube is not an absolutely smooth surface, the condensed water condensed on the outer wall of the inner tube cannot completely fall into the water tank, and some of the condensed water will be retained on the outer wall of the inner tube. This part of the condensed water will evaporate quickly under the blowing of biogas, and the generated water vapor will be mixed into the biogas again, reducing the combustion efficiency of the biogas. In view of this, we propose an internal combustion biogas torch. Summary of the invention

[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. Example

[0027] See also Figure 1-Figure 5 As shown, this embodiment provides an internal combustion biogas torch, including a base, a torch barrel 1 and an automatic ignition system 2 are fixedly connected to the upper surface of the base, the torch barrel 1 is sleeved on the outside of the automatic ignition system 2, an air intake pipe 3 is fixedly connected to one side of the torch barrel 1, one end of the air intake pipe 3 is fixedly connected to the automatic ignition system 2, and one end of the air intake pipe 3 located outside the torch barrel 1 is connected to the biogas pipeline. After the biogas is injected into the automatic ignition system 2 through the air intake pipe 3, the automatic ignition system 2 ignites the biogas to make the harmful gas The body is fully burned. The automatic ignition system 2 is a prior art and will not be elaborated here. Please refer to the patent document (201020551661.0). A dehumidification mechanism 4 is provided in the middle section of the intake pipe 3. The dehumidification mechanism 4 filters the biogas in the intake pipe 3 and removes the water vapor in the biogas, thereby improving the efficiency of biogas combustion. The dehumidification mechanism 4 includes an assembly cylinder 41 fixedly connected to the wall of the intake pipe 3. The assembly cylinder 41 is communicated with the inside of the intake pipe 3. A U-shaped tube 42 is provided inside the assembly cylinder 41. The U-shaped tube Both ends of the U-shaped tube 42 are fixedly connected with a corrugated hose 43, and the upper surface of the assembly tube 41 is fixedly connected with a chiller 44. The upper ends of the two corrugated hoses 43 penetrate the assembly tube 41 and are respectively connected with the water inlet and the water outlet of the chiller 44. After the chiller 44 is started, cold water flows through the U-shaped tube 42. The cold water cools the wall of the U-shaped tube 42 through heat exchange. When the biogas flows through the outer side of the wall of the U-shaped tube 42, the water vapor in the biogas condenses on the surface of the U-shaped tube 42, thereby achieving the effect of filtering out the water vapor in the biogas. The U-shaped tube 42 A oscillating mechanism 5 is provided on the outside, which is used to drive the U-shaped tube 42 to oscillate. By making the U-shaped tube 42 oscillate at a high frequency, condensed water is swung away to prevent condensed water from being retained on the outside of the tube wall of the U-shaped tube 42. A water tank 7 is fixedly connected to the upper surface of the base, and the lower end of the assembly cylinder 41 is connected to the inside of the water tank 7. By making the condensed water drip naturally or be swung into the inside of the water tank 7 for collection, the condensed water is prevented from evaporating again under the blowing of biogas, so that water vapor is mixed with biogas again and enters the automatic ignition system 2, thereby reducing the combustion efficiency of biogas.

[0028] In order to drive the U-shaped tube 42 to oscillate at high frequency and throw off the condensed water attached to the surface of the U-shaped tube 42, a oscillating mechanism 5 is arranged on the outer side of the U-shaped tube 42, and the structure of the oscillating mechanism 5 is refined. The oscillating mechanism 5 includes a sleeve frame 51 slidably sleeved on the outer wall of the U-shaped tube 42, a tooth block 52 is fixedly connected to the inner wall of the sleeve frame 51, a serrated plate 53 is fixedly connected to the side of the outer wall of the U-shaped tube 42 close to the tooth block 52, and the tooth groove of the serrated plate 53 is movably sleeved on the outer side of the tooth end of the tooth block 52, and a reciprocating mechanism 6 is arranged on one side of the sleeve frame 51, and the reciprocating mechanism 6 is used to drive the sleeve frame 51 to reciprocate vertically. When the sleeve frame 51 drives the tooth block 52 to reciprocate vertically, the tooth block 52 successively contacts with several tooth grooves of the serrated plate 53, and the tooth block 52 slides along the inner wall of the tooth groove When the U-shaped tube 42 is pushed to move, the U-shaped tube 42 is vibrated at a high frequency to shake off the condensed water, thereby preventing part of the condensed water from being retained on the outer side of the tube wall of the U-shaped tube 42, causing the part of the condensed water to evaporate again, and the generated water vapor is mixed with the biogas. The oscillating mechanism 5 also includes a U-shaped frame 54 fixedly connected to the lower surface of the sleeve frame 51, and the U-shaped frame 54 is movably sleeved on the bottom of the U-shaped tube 42. The sleeve frame 51 drives the U-shaped frame 54 to move back and forth vertically, so that when the U-shaped frame 54 rises to the highest point, the U-shaped frame 54 lifts the U-shaped tube 42 upward, thereby causing the U-shaped tube 42 to move back and forth vertically while swinging, so that the oscillating mechanism 5 can drive the U-shaped tube 42 to vibrate in multiple directions, thereby improving the efficiency of shaking off the condensed water on the surface of the U-shaped tube 42.

[0029] In order to drive the sleeve frame 51 to move vertically back and forth, enhance the effect of high-frequency vibration of the U-shaped tube 42, and enhance the effect of removing the condensed water attached to the outer wall of the U-shaped tube 42, a reciprocating mechanism 6 is provided on one side of the sleeve frame 51, and the reciprocating mechanism 6 drives the sleeve frame 51 to move up and down. Figure 4 , the structure of the reciprocating mechanism 6 is refined. The reciprocating mechanism 6 includes a hollow frame 61 fixedly connected to the inner wall of the intake pipe 3. The side wall of the hollow frame 61 is rotatably connected to a rotating shaft 62. One end of the rotating shaft 62 is fixedly connected to a fan 63. The other end of the rotating shaft 62 is fixedly connected to an eccentric wheel 64. The outer wall of the circumference of the eccentric wheel 64 is slidably sleeved with a cover 65. One side of the cover 65 is fixedly connected to the sleeve frame 51. The side of the sleeve frame 51 away from the cover 65 is fixedly connected to a sliding sleeve 66. The inner wall of the cylinder 41 is fixedly connected to a guide frame 67, and a sliding sleeve 66 is slidably mounted on the outer side of the guide frame 67. The sliding sleeve 66 cooperates with the guide frame 67 so that the sleeve frame 51 can only move vertically along a fixed path. When the biogas flows through the surface of the fan 63, the fan 63 drives the eccentric wheel 64 to rotate through the rotating shaft 62, and the outer wall of the eccentric wheel 64 pushes the cover shell 65 and the sleeve frame 51 to move back and forth vertically, thereby driving the U-shaped tube 42 to vibrate in multiple directions with high frequency, and throwing off the condensed water on its outer wall.

[0030] The side portions of the U-shaped tube 42 close to and away from the guide frame 67 do not contact the side walls of the sleeve frame 51, and the side walls of the U-shaped tube 42 away from the tooth block 52 contact the side walls of the sleeve frame 51, so that the sleeve frame 51 restricts the position of the U-shaped tube 42, so that the U-shaped tube 42 can swing in the axial direction of the intake pipe 3, that is, refer to Figure 4 As shown, the left and right sides of the U-shaped tube 42 are in contact with the inner wall of the sleeve frame 51, and there is a certain gap between the front and rear ends of the U-shaped tube 42 and the inner wall of the sleeve frame 51, so that the U-shaped tube 42 can only move forward and backward but cannot move left and right, thereby preventing the U-shaped tube 42 from throwing the condensed water on its surface into the inside of the intake pipe 3, making it impossible to completely discharge the condensed water from the intake pipe 3, while ensuring the stable engagement of the tooth block 52 and the serrated plate 53.

[0031] In summary, the working principle of the present scheme is as follows: start the chiller 44, pass cold water into the U-shaped tube 42, so that the wall of the U-shaped tube 42 is cooled, and the biogas is injected into the automatic ignition system 2 through the air inlet pipe 3 and then ignited, so that the harmful gas is fully burned. After the biogas flows through the surface of the U-shaped tube 42, the water vapor mixed in the biogas is condensed on the outer wall of the U-shaped tube 42, and then the water vapor mixed in the biogas is filtered out, thereby improving the combustion efficiency of the biogas. When the biogas flows through the surface of the fan 63, the fan 63 drives the eccentric wheel 64 to rotate, so that the sleeve 51 moves vertically back and forth, thereby making the U-shaped tube 42 vibrate in multiple directions with high frequency, and the condensed water attached to the outer wall of the U-shaped tube 42 is thrown and dripped into the water tank 7, so as to realize the complete collection of the condensed water, and prevent the condensed water from evaporating again under the blowing of the biogas, so that the water vapor is mixed into the biogas again, and the combustion efficiency of the biogas is reduced.
