Description

Technical Field

[0001] This utility model relates to the technical field of biogas drying devices, and in particular to a biogas drying device for leachate discharge. Background Technology

[0002] Landfill leachate generates a large amount of biogas during treatment. This biogas may contain high levels of moisture, which needs to be removed using appropriate drying equipment to prevent equipment corrosion and avoid pipeline blockage or reduced combustion efficiency during biogas transportation and utilization.

[0003] Traditional biogas drying typically uses condenser dryers. Their main working principle is that after gas enters the dryer, it is cooled by a heat exchanger and cooler. As the gas temperature drops, the water vapor condenses into moisture. As the gas temperature decreases further, the water vapor condenses into liquid water, which is then separated, thus drying the gas. The water is then removed by an internal moisture separator. However, in actual use, it has been found that the internal components of the biogas condenser dryer generate a large amount of heat during operation. This heat is difficult to dissipate in time, affecting the normal operation of the equipment and reducing the condensation and drying effect of the biogas. Utility Model Content

[0004] The technical problem this invention aims to solve is that when a biogas refrigerated dryer is in use, its internal components generate a large amount of heat, which is difficult to dissipate and discharge in a timely manner, thus affecting the normal operation of the equipment and reducing the condensation and drying effect of biogas.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a biogas drying device for leachate discharge, including a refrigerated dryer, a ventilation device and a fixing device. The surface of the refrigerated dryer is equipped with an air inlet pipe and an air outlet pipe. The surface of the refrigerated dryer is provided with a control panel. The bottom surface of the refrigerated dryer is provided with a ventilation device by means of the fixing device. The ventilation device dissipates heat from the internal equipment of the refrigerated dryer by means of fan blades and auxiliary plates.

[0006] The effect achieved by the above components is as follows: When using a refrigerated dryer to dry biogas produced from landfill leachate, first connect the corresponding connecting pipes to the air inlet and outlet pipes of the refrigerated dryer, and install the ventilation device on the inner wall of the refrigerated dryer with the help of a fixing device. Then, operate the control panel to debug and run the refrigerated dryer, so that the biogas enters the interior of the refrigerated dryer and is dried by the corresponding equipment to separate the moisture in the biogas. At the same time, start the ventilation device below the refrigerated dryer to exhaust the heat generated by the internal operating equipment of the refrigerated dryer.

[0007] Preferably, the ventilation device includes a support frame installed at the bottom of the refrigerated dryer by means of a fixing device. A mounting frame is fixedly connected to the inner wall of the support frame. A rotating shaft is rotatably arranged on the inner wall of the mounting frame. Fan blades are installed on the arc surface of the rotating shaft. A servo motor is installed on the surface of the support frame. A belt is installed on the output end of the servo motor and the arc surface of the rotating shaft by means of rollers. An auxiliary plate is installed on the inner wall of the support frame. The cross-section of the auxiliary plate is triangular.

[0008] The effect achieved by the above components is that when the refrigerated dryer is drying biogas, it can quickly dissipate and discharge the high temperature heat generated by the internal operating equipment, thereby ensuring that the temperature of the equipment is maintained at a normal level and ensuring the normal operation of the refrigerated dryer.

[0009] Preferably, the ventilation device includes a stabilizing plate mounted on a support frame, wherein the stabilizing plate assists in the stable operation of the belt.

[0010] The effect achieved by the above components is that, by setting up the stabilizing plate, the belt is more stably installed on the shaft and the output end of the servo motor, making it less likely to come off during operation and ensuring the stable rotation of the fan blades.

[0011] Preferably, two positioning plates are fixedly connected to the arc surface of the rotating shaft, and the two positioning plates limit and stabilize the installation position of the rotating shaft.

[0012] The effect achieved by the above components is that, through the setting of the positioning plate, the rotating shaft is more stably installed in the inner wall of the mounting frame, and it is not easy to loosen or detach abnormally, thus ensuring the normal rotation of the rotating shaft.

[0013] Preferably, the auxiliary plate has several evenly distributed auxiliary grooves on both sides of its surface.

[0014] The effect achieved by the above components is that, by setting up the auxiliary slot, when the fan blades extract the heat generated by the refrigerated dryer and blow it onto the surface of the auxiliary plate, they can be more stably discharged to both sides along the inner wall of the auxiliary slot, thereby improving the performance of the ventilation device.

[0015] Preferably, the fixing device includes a mounting plate fixedly connected to the four sides of the support frame. The mounting plate has mounting grooves on both sides of its surface, and an insert plate installed on the surface of the refrigerated dryer is inserted into the inner wall of the mounting groove.

[0016] The effect achieved by the above components is that the support frame will be stably installed at the bottom of the refrigerated dryer, making the installation and use of the ventilation device more convenient and quick, thus facilitating the use of the device and the inspection and maintenance of the device.

[0017] Preferably, the fixing device includes an operating block mounted on the bolt, and the surface of the operating block is provided with a plurality of anti-slip protrusions.

[0018] The effect achieved by the above components is that the operation block makes the bolts easier and faster to use, thereby making the disassembly and assembly of the support frame more convenient and improving the ease of use of the ventilation device.

[0019] Preferably, a washer, which is a rubber sheet, is fitted onto the arc surface of the bolt.

[0020] The effect achieved by the above components is that, by setting the gasket, the bolts can fit more stably and securely when installed on the surface of the insert plate, thereby ensuring a stable connection between the mounting plate and the insert plate.

[0031] Figure 1 and Figure 2 The biogas drying device for leachate discharge shown includes a refrigerated dryer 1, a ventilation device 5, and a fixing device 6. An air inlet pipe 3 and an air outlet pipe 4 are installed on the surface of the refrigerated dryer 1. A control panel 2 is provided on the surface of the refrigerated dryer 1. The ventilation device 5 is provided on the bottom surface of the refrigerated dryer 1 with the help of the fixing device 6. The ventilation device 5 dissipates heat from the internal equipment of the refrigerated dryer 1 by means of fan blades 55 and auxiliary plates 58.

[0032] Figure 1 , Figure 2 and Figure 3 The ventilation device 5 shown includes a support frame 51 mounted at the bottom of the refrigerated dryer 1 by means of a fixing device 6. A mounting frame 52 is fixedly connected to the inner wall of the support frame 51. A rotating shaft 53 is rotatably mounted on the inner wall of the mounting frame 52. Fan blades 55 are mounted on the arc surface of the rotating shaft 53. A servo motor 56 is mounted on the surface of the support frame 51. A belt 57 is mounted on the output end of the servo motor 56 and the arc surface of the rotating shaft 53 via rollers. An auxiliary plate 58 is mounted on the inner wall of the support frame 51. The auxiliary plate 58 has a triangular cross-section. When using the refrigerated dryer 1 to dry the biogas produced from landfill leachate, firstly, the corresponding connecting pipes are connected to the air inlet pipe 3 and air outlet pipe 4 of the refrigerated dryer 1. Then, the ventilation device 5 is mounted on the inner wall of the refrigerated dryer 1 by means of the fixing device 6. Next, the control panel 2 is operated to debug and run the refrigerated dryer 1, allowing the biogas to... When biogas enters the refrigerated dryer 1, it is dried by the corresponding equipment to separate the moisture in the biogas. At the same time, the servo motor 56 on the support frame 51 is started. The servo motor 56 drives the rotating shaft 53 to rotate through the running connection of the belt 57, thereby causing the rotating shaft 53 inside the mounting frame 52 to rotate. This causes the fan blades 55 fixedly connected to the rotating shaft 53 to rotate at high speed. At this time, the fan blades 55 generate suction wind, thereby removing the heat generated by the internal operating equipment of the refrigerated dryer 1 and blowing it onto the auxiliary plate 58 below. Along the surface of the auxiliary plate 58, the heat is quickly dissipated outside the refrigerated dryer 1. At this time, when the refrigerated dryer 1 is drying biogas, it can quickly dissipate and remove the high temperature heat generated by the internal operating equipment, thereby ensuring that the temperature of the equipment is maintained at a normal level and ensuring the normal operation of the refrigerated dryer 1.

[0033] Figure 1 , Figure 2 and Figure 3 The ventilation device 5 shown includes a stabilizing plate 510 mounted on a support frame 51. The stabilizing plate 510 assists in the stable operation of the belt 57. By setting the stabilizing plate 510, the belt 57 is more stably mounted on the shaft 53 and the output end of the servo motor 56, making it less likely to detach during operation and ensuring the stable rotation of the fan blades 55. Two positioning plates 54 are fixedly connected to the arc surface of the shaft 53. The two positioning plates 54 limit and stabilize the installation position of the shaft 53. By setting the positioning plates 54, the shaft 53 is more stably mounted in the inner wall of the mounting frame 52, making it less likely to loosen or detach abnormally, and ensuring the normal rotation of the shaft 53. Several evenly distributed auxiliary grooves 59 are opened on both sides of the surface of the auxiliary plate 58. By setting the auxiliary grooves 59, when the fan blades 55 extract the heat generated by the refrigerated dryer 1 and blow it onto the surface of the auxiliary plate 58, they can be more stably discharged to both sides along the inner wall of the auxiliary grooves 59, improving the performance of the ventilation device 5.

[0034] Figure 1 and Figure 4 The fixing device 6 shown includes a mounting plate 61 fixedly connected to the four sides of the support frame 51. Mounting grooves 62 are respectively opened on both sides of the mounting plate 61, and insert plates 63 installed on the surface of the refrigerated dryer 1 are inserted into the inner wall of the mounting grooves 62. Bolts 64 are passed through the surface of the insert plates 63, where the bolts 64 assist in the connection and fixation between the insert plates 63 and the mounting plate 61. When the ventilation device 5 is installed at the bottom of the refrigerated dryer 1, the refrigerated dryer 1 is first placed on the surface of the support frame 51. At this time, the mounting grooves 62 on the surface of the insert plates 63 fixedly connected at the four corners of the support frame 51 will be inserted into the two insert plates 63 fixedly connected at the four corners of the refrigerated dryer 1. Then, the bolts 64 are passed through the surface of the insert plates 63, connecting the bolts 64 to the inner wall bolts 64 of the mounting grooves 62, thereby stabilizing the connection between the insert plates 63 and the connecting plate. At this time, the support frame 51 will be stably installed at the bottom of the refrigerated dryer 1. Therefore, the ventilation device 5 is more convenient and quick to install and use, making it easier to use and maintain the device.

[0035] Figure 1 and Figure 4The fixing device 6 shown includes an operating block 65 mounted on the bolt 64. The surface of the operating block 65 is provided with several anti-slip protrusions. The operation block 65 makes it easier and faster to use the bolt 64, thereby making it easier to assemble and disassemble the support frame 51 and improving the ease of use of the ventilation device 5. A gasket 66 is fitted on the arc surface of the bolt 64. The gasket 66 is a rubber sheet. The gasket 66 makes it more stable and fits the bolt 64 when it is installed on the surface of the insert plate 63, thereby ensuring a stable connection between the mounting plate 61 and the insert plate 63.

[0036] Working Principle: When using the refrigerated dryer 1 to dry the biogas produced from landfill leachate, first connect the corresponding connecting pipes to the air inlet pipe 3 and air outlet pipe 4 of the refrigerated dryer 1, and install the ventilation device 5 on the inner wall of the refrigerated dryer 1 with the help of the fixing device 6. Then, operate the control panel 2 to debug and run the refrigerated dryer 1, allowing the biogas to enter the interior of the refrigerated dryer 1 and be dried by the corresponding equipment, separating the moisture in the biogas. At the same time, start the servo motor 56 on the support frame 51. The servo motor 56 will drive the rotation of the rotating shaft 53 through the running connection of the belt 57, thereby... The rotating shaft 53 inside the mounting frame 52 rotates, causing the fan blades 55 fixedly connected to the rotating shaft 53 to rotate at high speed. At this time, the fan blades 55 generate suction wind, thereby removing the heat generated by the internal operating equipment of the refrigerated dryer 1 and blowing it onto the auxiliary plate 58 below. Along the surface of the auxiliary plate 58, the heat is quickly dissipated outside the refrigerated dryer 1. At this time, when the refrigerated dryer 1 is drying biogas, it can quickly dissipate and remove the high temperature heat generated by the internal operating equipment, thereby ensuring that the temperature of the equipment is maintained at a normal level and ensuring the normal operation of the refrigerated dryer 1.

[0037] When installing the ventilation device 5 at the bottom of the refrigerated dryer 1, first place the refrigerated dryer 1 on the surface of the support frame 51. At this time, the mounting grooves 62 on the surface of the insert plates 63 fixedly connected at the four corners of the support frame 51 will be interlocked with the two insert plates 63 fixedly connected at the four corners of the refrigerated dryer 1. Then, the bolts 64 are passed through the surface of the insert plates 63, so that the bolts 64 are connected with the inner wall bolts 64 of the mounting grooves 62, thereby stabilizing the connection between the insert plates 63 and the connecting plate. At this time, the support frame 51 will be stably installed at the bottom of the refrigerated dryer 1. At this time, the ventilation device 5 will be more convenient and quick to install and use, thus making it easier to use the device and also easier to inspect and maintain the device.
