Description

Technical Field

[0001] This invention relates to the field of natural gas combustion device technology, specifically to a natural gas combustion device for a natural gas drying furnace and its usage method. Background Technology

[0002] Natural gas burners are one of the main combustion devices for natural gas. According to the combustion control method, burners can be divided into single-stage burners, two-stage burners, and proportional control burners. Natural gas has a wide range of applications, which can be roughly divided into two aspects: energy and chemical industry. In the energy sector, natural gas combustion equipment is the main component, and natural gas burners are one of the main combustion devices for natural gas.

[0003] Current natural gas combustion devices typically burn natural gas directly without pre-dehumidifying it. Natural gas containing moisture is difficult to burn completely, resulting in low combustion efficiency and suboptimal heat production. Furthermore, current dehumidification processes often require circulating coolant to improve moisture condensation, significantly increasing manufacturing costs and complexity. Additionally, current devices often fail to ensure complete combustion, hindering the mixing of natural gas with oxygen-containing air and thus limiting the device's overall efficiency in utilizing natural gas. Summary of the Invention

The dehumidification chamber is installed at the middle position of the bottom of the treatment chamber, and the second spiral heat exchange tube is arranged on the outside of the dehumidification chamber. The bottom end of the second spiral heat exchange tube is connected to the bottom end of the inside of the dehumidification chamber, and the top end of the second spiral heat exchange tube is connected to the output end of the first spiral heat exchange tube. The input end of the solenoid valve is connected to the inner top of the dehumidification chamber. An internally threaded tube is threaded at the bottom of the inner side of the dehumidification chamber, and a cylinder is threaded on the inner side of the internally threaded tube. Through holes are evenly opened on the outer side of the cylinder. A drying package is arranged inside the cylinder, and a bottom cover is installed at the bottom of the internally threaded tube.

[0007] Preferably, the turbulence assembly includes a rotating rod, a spiral conveying slurry, an air jet pipe, a rotating cylinder, a bearing, and a fan. A bearing is installed at the end of the connecting pipe body away from the connecting chamber, and a rotating cylinder is installed inside the bearing. Air jet pipes are evenly installed inside the rotating cylinder, and the end of the air jet pipe away from the connecting chamber extends to the outside of the rotating cylinder. A rotating rod is installed at the center of the rotating cylinder, and a spiral conveying slurry is installed on the outside of the rotating rod. A fan is installed at the end of the rotating rod away from the rotating cylinder.

[0008] Preferably, the inner side of the rotating cylinder has a funnel-shaped structure, and the interior of the connecting chamber has a funnel-shaped structure.

[0009] Preferably, a fixing ring is installed on the side of the air guide pipe near the combustion fan box, and a connecting screw is provided on the outer thread of the fixing ring. The air guide pipe is fixedly connected to the air inlet of the combustion fan box through the fixing ring and the connecting screw.

[0010] Preferably, two sets of mounting frames are installed on the inner side of the air intake pipe, and a filter screen is installed on the inner side of the mounting frames.

[0011] Preferably, a mounting bracket is installed on the outer side of the connecting pipe body away from the connecting chamber, and fixing screws are symmetrically threaded at the four corners of the outer side of the mounting bracket. Fixing brackets are symmetrically installed on both sides of the bottom of one end of the mounting bracket, and the end of the fixing bracket away from the mounting bracket is fixedly connected to the outer side of the processing chamber.

[0012] Preferably, the inlet end of the air duct is tangent to the top of the outer side of the treatment chamber, and the air inlet pipe is tangent to the bottom of the outer side of the treatment chamber.

[0013] Preferably, an annular groove is provided at the top edge of the bottom cover, a sealing ring that cooperates with the annular groove is installed at the non-center position of the bottom of the processing chamber, and a handle is installed at the bottom of the bottom cover.

[0014] Preferably, the method of using the natural gas combustion device of the natural gas dryer includes the following steps:

[0015] First, connect the input end of the pneumatic regulating valve to the external natural gas supply pipe. Then, control the pneumatic regulating valve to deliver natural gas to the inside of the first spiral heat exchange tube at a suitable flow rate. The natural gas inside the first spiral heat exchange tube enters the inside of the dehumidification chamber after passing through the second spiral heat exchange tube. Then, it is delivered into the annular pipe through the solenoid valve and then sprayed into the inside of the connecting chamber through the jet hole.

[0016] Second, control the combustion blower to work. When the combustion blower is working, it will draw air from inside the processing chamber, forcing outside air into the processing chamber and spiraling upwards inside the processing chamber. Then, the outside air enters the combustion blower through the air duct and is then delivered into the connecting chamber from the output end of the combustion blower. Finally, the two are ejected together from the jet pipe. Then, control the ignition device to ignite the ejected mixed gas.

[0017] Third, the flame transfers some heat to the outside of the connecting pipe, and then the connecting pipe gradually heats the natural gas inside the first spiral heat exchange tube. The heated natural gas enters the second spiral heat exchange tube and gradually condenses.

[0018] Fourth, the air entering the processing chamber from the outside will also cool down the second spiral heat exchange tube. Then, the natural gas, along with the condensed water droplets, will be sprayed to the outside of the cylinder. The water droplets will pass through the through holes and be absorbed by the drying pack inside the cylinder. The dehumidified natural gas will then enter the interior of the connecting chamber again through the solenoid valve, forming a stable natural gas transportation and combustion process.

[0019] Compared with the prior art, the present invention provides a natural gas combustion device for a natural gas dryer and its method of use, which has the following beneficial effects:

[0020] 1. In this invention, after ignition at the outlet of the connecting pipe, the flame gradually heats the connecting pipe. Then, the pneumatic regulating valve is controlled to deliver natural gas into the interior of the first spiral heat exchange tube. As the natural gas passes through the first spiral heat exchange tube, the connecting pipe gradually heats the natural gas inside the first spiral heat exchange tube. The heated natural gas enters the interior of the second spiral heat exchange tube and gradually condenses. Then, the natural gas, along with the condensed water droplets, is sprayed towards the outside of the cylinder. The water droplets are absorbed by the drying pack inside the cylinder, while the natural gas moves from bottom to top inside the dehumidification chamber. Finally, the natural gas is delivered to the interior of the annular pipe through the solenoid valve, and then sprayed into the interior of the connecting chamber through the jet hole, where it mixes with the air inside the connecting chamber and is finally ignited. The heat from the flame at the outlet of the connecting pipe is used to dehumidify the natural gas, which improves the heat utilization efficiency of the entire device and the utilization efficiency of the natural gas, ensuring the heat generation effect of the entire device.

[0021] 2. When the combustion fan is working, the present invention forces outside air into the processing chamber. Due to the positional relationship between the air inlet pipe and the air guide pipe, the air entering the processing chamber will spiral upward along the interior of the processing chamber. During this process, the natural gas located inside the second spiral heat exchange tube can be cooled, which greatly improves the cooling effect of the natural gas inside the second spiral heat exchange tube. This causes the water vapor in the natural gas inside the second spiral heat exchange tube to condense rapidly, further improving the dehumidification effect of the dehumidification component on the natural gas. Moreover, the improved dehumidification effect of the dehumidification component on the natural gas is achieved without adding any devices or electrical products.

[0022] 3. In this invention, after the outside air is delivered into the connecting chamber by the combustion-supporting fan, the moving air drives the fan to rotate. The dehumidified air also enters the interior of the annular pipe and is injected into the interior of the connecting chamber through the jet holes. The rotating fan forces the outside air and natural gas to mix together and then flow together towards the ignition device. The rotation of the fan also drives the rotating rod and rotating cylinder to rotate. The spiral conveying slurry rotating on the outside of the rotating rod further stirs the outside air and natural gas, making the two more evenly mixed. Then the mixed gas is ejected through multiple sets of jet pipes. At this time, the ignition device is controlled to ignite the gas ejected from the jet pipes, so that the entire device can work stably. Attached Figure Description

The drying package 702 is provided inside the cylinder 704, and the bottom cover 705 is installed at the bottom of the internally threaded tube 706.

[0036] Furthermore, the turbulence assembly 8 includes a rotating rod 801, a spiral conveying slurry 802, an air jet pipe 803, a rotating cylinder 804, a bearing 805, and a fan 806. The bearing 805 is installed at the end of the connecting pipe body 9 away from the connecting chamber 5, and the rotating cylinder 804 is installed inside the bearing 805. The air jet pipe 803 is evenly installed inside the rotating cylinder 804. The end of the air jet pipe 803 away from the connecting chamber 5 extends to the outside of the rotating cylinder 804. The rotating rod 801 is installed at the center of the rotating cylinder 804. The spiral conveying slurry 802 is installed on the outside of the rotating rod 801. The fan 806 is installed at the end of the rotating rod 801 away from the rotating cylinder 804.

[0037] Furthermore, the inner side of the rotating cylinder 804 has a funnel-shaped structure, and the interior of the connecting chamber 5 has a funnel-shaped structure, which helps the mixed gas to flow from the connecting chamber 5 into the connecting pipe 9.

[0038] Furthermore, a fixing ring is installed on the side of the air guide pipe 2 near the air box of the combustion blower 1, and a connecting screw is provided on the outer thread of the fixing ring. The air guide pipe 2 is fixedly connected to the air inlet of the air box of the combustion blower 1 through the fixing ring and the connecting screw, which helps to connect one end of the air guide pipe 2 to the air inlet of the air box of the combustion blower 1.

[0039] Furthermore, two sets of mounting frames are installed on the inner side of the air intake pipe 13, and a filter screen 16 is installed on the inner side of the mounting frame, which helps to filter the outside air entering the processing chamber 12.

[0040] Furthermore, a mounting bracket 11 is installed on the outer side of the connecting pipe 9 away from the connecting chamber 5, and fixing screws are symmetrically threaded at the four corners of the outer side of the mounting bracket 11. Fixing brackets are symmetrically installed on both sides of the bottom of one end of the mounting bracket 11, and the end of the fixing bracket away from the mounting bracket 11 is fixedly connected to the outer side of the processing chamber 12, which helps to fix the entire device onto the corresponding drying oven.

[0041] Furthermore, the inlet end of the air duct 2 is tangent to the top of the outer side of the processing chamber 12, and the air inlet pipe 13 is tangent to the bottom of the outer side of the processing chamber 12, which helps the air entering the processing chamber 12 to move spirally upward inside the processing chamber 12, thereby improving the cooling effect of the outside air on the second spiral heat exchange pipe 701.

[0042] Furthermore, an annular groove is provided at the top edge of the bottom cover 705, and a sealing ring that cooperates with the annular groove is installed at the non-center position of the bottom of the treatment chamber 12. A handle is installed at the bottom of the bottom cover 705, which helps to improve the sealing effect inside the dehumidification chamber 703.

[0043] Furthermore, the method of using the natural gas combustion device of the natural gas dryer is as follows:

[0044] First, connect the input end of the pneumatic regulating valve 4 to the external natural gas supply pipe. Then, control the pneumatic regulating valve 4 to deliver natural gas to the inside of the first spiral heat exchange tube 6 at a suitable flow rate. The natural gas inside the first spiral heat exchange tube 6 enters the inside of the dehumidification chamber 703 after passing through the second spiral heat exchange tube 701. Then, it is delivered into the annular pipe 17 through the solenoid valve 3 and then sprayed into the inside of the connecting chamber 5 through the jet hole 15.

[0045] Second, control the combustion blower 1 to work. When the combustion blower 1 is working, it will draw the air inside the processing chamber 12, forcing the outside air into the processing chamber 12 and spiraling upward along the inside of the processing chamber 12. Then the outside air enters the combustion blower 1 through the air guide pipe 2, and is then sent into the interior of the connecting chamber 5 from the output end of the combustion blower 1. Finally, the two are sprayed out together from the jet pipe 803. Then control the ignition device 10 to ignite the sprayed mixed gas.

[0046] Third, the flame transfers some heat to the outside of the connecting pipe 9, and then the connecting pipe 9 gradually heats the natural gas inside the first spiral heat exchange pipe 6. The heated natural gas enters the second spiral heat exchange pipe 701 and gradually condenses.

[0047] Fourth, the air entering the processing chamber 12 from the outside will also cool down the second spiral heat exchange tube 701. Then, the natural gas, along with the condensed water droplets, will be sprayed to the outside of the cylinder 704. The water droplets will pass through the through hole 707 and be absorbed by the drying package 702 inside the cylinder 704. The dehumidified natural gas will then enter the interior of the connecting chamber 5 again through the solenoid valve 3, forming a stable natural gas transportation and combustion process.

[0048] Example 1, such as Figure 4-5As shown, the bottom cover 705 is periodically rotated counterclockwise by the handle, causing the bottom cover 705 and the cylinder 704 to leave the inside of the dehumidification chamber 703 together. Then, the cylinder 704 is manually rotated counterclockwise to separate the cylinder 704 from the inside of the internal threaded pipe 706. Then, all the dryer packs 702 inside the cylinder 704 are emptied and replaced with new dryer packs 702. Then, the above operations are reversed to reinstall the cylinder 704 into the dehumidification chamber 703. This ensures the dehumidification effect of the device on natural gas.

[0049] Example 2, as Figure 4-5 As shown, after ignition at the outlet of the connecting pipe 9, the flame gradually heats the connecting pipe 9. Then, the pneumatic regulating valve 4 controls the natural gas to be delivered into the first spiral heat exchange tube 6. During the process of the natural gas passing through the first spiral heat exchange tube 6, the connecting pipe 9 gradually heats the natural gas inside the first spiral heat exchange tube 6. The heated natural gas enters the second spiral heat exchange tube 701 and gradually condenses. Then, the natural gas, along with the condensed water droplets, is sprayed towards the outside of the cylinder 704. The water droplets are absorbed by the drying package 702 inside the cylinder 704, while the natural gas moves from bottom to top inside the dehumidification chamber 703. Finally, the natural gas is delivered into the annular pipe 17 through the solenoid valve 3, and then sprayed into the connecting chamber 5 through the jet hole 15, where it mixes with the air inside the connecting chamber 5 and is finally ignited. The heat of the flame at the outlet of the connecting pipe 9 is used to dehumidify the natural gas, which improves the heat utilization efficiency of the entire device and the utilization efficiency of the natural gas, ensuring the heat generation effect of the entire device.

[0050] Working principle: Before use, connect the device to the power supply. First, connect the input end of the pneumatic regulating valve 4 to the external natural gas supply pipe. Then, control the pneumatic regulating valve 4 to deliver natural gas at a suitable flow rate into the interior of the first spiral heat exchange tube 6. The natural gas inside the first spiral heat exchange tube 6 enters the interior of the dehumidification chamber 703 after passing through the second spiral heat exchange tube 701. Then, it is delivered into the annular pipe 17 through the solenoid valve 3, and then sprayed into the interior of the connecting chamber 5 through the jet nozzle 15. During this process, the motor of the combustion fan 1 is controlled by the control panel 14. When the combustion blower 1 operates at a suitable speed, it draws air from the processing chamber 12, forcing outside air into the chamber and causing it to spiral upwards. The outside air then enters the combustion blower 1 through the duct 2 and is then delivered into the connecting chamber 5 from its output. Finally, both gases are ejected from the jet pipe 803. The ignition device 10 then ignites the ejected mixture. As the flame burns continuously at the outlet of the connecting pipe 9, it transfers some heat to the connecting pipe. Outside the body 9, the connecting pipe body 9 gradually heats the natural gas inside the first spiral heat exchange tube 6. The heated natural gas enters the second spiral heat exchange tube 701 and gradually condenses. Meanwhile, the air entering the processing chamber 12 from the outside also blows the second spiral heat exchange tube 701 to cool it down. Then, the natural gas, along with the condensed water droplets, is sprayed towards the outside of the cylinder 704. The water droplets pass through the through hole 707 and are absorbed by the drying bag 702 inside the cylinder 704. The dehumidified natural gas then re-enters the connecting chamber 5 through the solenoid valve 3. After the outside air and natural gas are transported into the connecting chamber 5 together, the fan 806 is driven to rotate. The rotating fan 806 forces the outside air and natural gas to mix together and then flow towards the ignition device 10. The rotation of the fan 806 also drives the rotating rod 801 and the rotating cylinder 804 to rotate. The spiral conveying slurry 802 rotating outside the rotating rod 801 further stirs the outside air and natural gas. Then, the mixed gas is sprayed out through multiple sets of jet pipes 803, forming a stable natural gas transportation and combustion process.

The natural gas combustion device for a natural gas dryer according to claim 1, characterized in that: The inlet end of the air duct (2) is tangent to the top of the outer side of the processing chamber (12), and the air inlet pipe (13) is tangent to the bottom of the outer side of the processing chamber (12).

7. The natural gas combustion device for a natural gas dryer according to claim 1, characterized in that: An annular groove is provided at the top edge of the bottom cover (705), and a sealing ring that cooperates with the annular groove is installed at the bottom of the processing chamber (12) at a non-center position. A handle is installed at the bottom of the bottom cover (705).

8. A method of using the natural gas combustion device of the natural gas dryer as described in any one of claims 1 to 7, comprising the following steps: First, connect the input end of the pneumatic regulating valve (4) to the external natural gas supply pipe, and then control the pneumatic regulating valve (4) to deliver natural gas to the inside of the first spiral heat exchange tube (6) at a suitable flow rate. The natural gas inside the first spiral heat exchange tube (6) enters the inside of the dehumidification chamber (703) after passing through the second spiral heat exchange tube (701), and then is delivered into the annular pipe (17) through the solenoid valve (3), and then sprayed into the inside of the connecting chamber (5) through the jet hole (15). Second, control the combustion blower (1) to work. When the combustion blower (1) is working, it will draw the air inside the processing chamber (12), forcing the outside air into the processing chamber (12) and spiraling up along the inside of the processing chamber (12). Then the outside air enters the combustion blower (1) through the air duct (2) and is then transported into the interior of the connecting chamber (5) from the output end of the combustion blower (1). Finally, the two are sprayed out together from the jet pipe (803). Then control the ignition device (10) to ignite the sprayed mixed gas. Third, the flame transfers some heat to the outside of the connecting pipe (9), and then the connecting pipe (9) gradually heats the natural gas inside the first spiral heat exchange pipe (6). The heated natural gas enters the second spiral heat exchange pipe (701) and gradually condenses. Fourth, the air entering the processing chamber (12) from the outside will also cool down the second spiral heat exchange tube (701). Then, the natural gas, along with the condensed water droplets, will be sprayed to the outside of the cylinder (704). The water droplets will pass through the through hole (707) and be absorbed by the drying pack (702) inside the cylinder (704). The dehumidified natural gas will then enter the interior of the connecting chamber (5) again through the solenoid valve (3), forming a stable natural gas transportation and combustion process.
