As shown in fig. 1 and 2, the utility model provides a heat conduction oil boiler, which comprises a boiler body 1 (the inner wall of the boiler body 1 is welded with a second heat conduction oil coil 16), a first smoke exhaust pipe 2 and a burner 18 arranged on two sides of the boiler body 1, a heat exchanger 3 arranged above the boiler body 1, a first oil inlet pipe 5 and a first oil outlet pipe 6 connected with the heat exchanger 3, and a heat conduction oil pump 7 connected with the first oil inlet pipe 5; the first oil outlet pipe 6 is connected with an oil inlet of the boiler body 1.
According to the utility model, the heat exchanger 3 is arranged above the boiler body 1, high-temperature flue gas (smoke discharging power is provided by the burner 18) discharged by the boiler body 1 during operation can enter the heat exchanger 3, and after a heated object is heated (after use), heat conducting oil is firstly fed into the heat exchanger 3 through the first oil inlet pipe 5 (driven by the heat conducting oil pump 7), so that heat contained in the high-temperature flue gas can be transferred to low-temperature heat conducting oil, and the heat conducting oil can be primarily heated; after the heat conduction oil is primarily heated, the heat conduction oil is sent into the boiler body 1 through the first oil outlet pipe 6 and is further heated to be within the using temperature range in the boiler body 1; after being heated in the boiler body 1 to a temperature within the range of use, the heat transfer oil is fed into a heat utilization device (the heat utilization device may be an asphalt heating tank) through a second oil outlet pipe 8. The above process is continuously circulated, thereby ensuring that the heat transfer oil can be continuously heated to within the use temperature range.
Because the heat conduction oil can be primarily heated in the heat exchanger 3, when the heat conduction oil is sent into the boiler body 1 for reheating, the consumption of the fuel (the fuel can be natural gas) of the boiler body 1 can be reduced, so that the energy consumption of the heat conduction oil boiler is reduced.
As shown in fig. 3, in one embodiment, a first heat conducting oil coil 4 is horizontally disposed in the heat exchanger 3; the first heat-conducting oil coil pipe 4 is in a serpentine shape, and the first oil inlet pipe 5 and the first oil outlet pipe 6 are respectively connected with an oil inlet and an oil outlet of the first heat-conducting oil coil pipe 4. According to the embodiment, the first heat conducting oil coil 4 is horizontally arranged in the heat exchanger 3, and the first heat conducting oil coil 4 is made to be in a snake shape, so that when high-temperature flue gas flows in the heat exchanger 3, the high-temperature flue gas can fully contact with the first heat conducting oil coil 4, and then heat energy contained in the flue gas is transferred to heat conducting oil in a pipe through the first heat conducting oil coil 4, so that the heat energy contained in the high-temperature flue gas can be fully recycled.
As shown in fig. 1, in one embodiment, the heat conduction oil boiler further comprises a controller, a second oil outlet pipe 8 connected with the oil outlet of the boiler body 1, a thermometer 9 arranged on the second oil outlet pipe 8, a fuel delivery pipe 10 connected with a burner 18, and a flow control valve 11 arranged on the fuel delivery pipe; the thermometer 9 and the flow control valve 11 are electrically connected with the controller, and the thermometer 9 is used for monitoring the temperature of the heat conduction oil output from the boiler body 1 in real time. When the thermometer 9 detects that the output temperature of the heat transfer oil is not in the use temperature range, the controller controls the flow control valve 11 so that the fuel flow entering the burner 18 can be dynamically adjusted, thereby dynamically adjusting the temperature in the boiler body 1 and the temperature of the high-temperature flue gas discharged by the boiler body 1, and when the temperature in the boiler body 1 and the temperature of the high-temperature flue gas discharged by the boiler body 1 are changed, the output temperature of the heat transfer oil is also changed, and therefore, when the output temperature of the heat transfer oil is abnormal, the temperature can be restored to the use temperature range through the dynamic adjustment.
In one embodiment, as shown in fig. 1, the conduction oil boiler further comprises a Y-filter 12; the Y-shaped filter 12 is arranged on the first oil inlet pipe 5. According to the embodiment, the Y-shaped filter 12 is arranged on the first oil inlet pipe 5, and the Y-shaped filter 12 can filter the heat conduction oil fed into the heat exchanger 3 and the boiler body 1, so that impurities in the heat conduction oil cannot enter the heat exchanger 3 and the pipelines in the boiler body 1 along with the heat conduction oil, the problem of pipeline blockage is avoided, and the heat exchange efficiency can be guaranteed not to be reduced while the heat conduction oil is conveyed in a normal circulation mode.
Further, the Y-filter 12 is located upstream of the heat conduction oil pump 7, so that impurities in the heat conduction oil do not enter the heat conduction oil pump 7 to damage the heat conduction oil pump 7.
In one embodiment, the Y-type filter 12 is not less than two. When the Y-type filter 12 is provided in plural, the filtering effect can be further ensured, and the cleaning frequency of the pipeline can be reduced while the heat exchange efficiency is improved.
As shown in fig. 3, in one embodiment, the heat exchanger 3 includes a plurality of sub heat exchangers 301 connected in series, and oil pipes 13 are connected to two adjacent sub heat exchangers 301. In this embodiment, a secondary smoke exhaust pipe 17 is disposed on the sub heat exchanger 301 located at the tail end of the smoke conveying path (in other embodiments, the secondary smoke exhaust pipe 17 is directly disposed on the heat exchanger 3), and after the heat exchange of the high-temperature smoke exhausted by the boiler body 1 is completed, the smoke (gas after natural gas combustion) is exhausted into the atmosphere through the secondary smoke exhaust pipe 17.
When a plurality of sub heat exchangers 301 connected in series with each other are provided, the distance that the heat transfer oil flows in the first heat transfer oil coil 4 can be extended, so that the flue gas has enough time to transfer more heat to the heat transfer oil, thereby further improving the utilization of the heat energy of the flue gas, and in addition, the fuel consumption of the boiler body 1 can be reduced because the heat transfer oil can be warmed up to a higher temperature in the heat exchanger 3.
As shown in fig. 3, in an embodiment, the outer wall of the oil delivery pipe 13 is covered with the first heat insulation layer 14, and the arrangement of the first heat insulation layer 14 can reduce heat loss when the heat conduction oil is transported between the sub heat exchangers 301, so as to further improve the recovery efficiency of the heat energy of the flue gas.
As shown in fig. 1, in one embodiment, the outer walls of the first oil inlet pipe 5, the first oil outlet pipe 6, and the second oil outlet pipe 8 are all covered with a second heat insulation layer 15. The provision of the second insulating layer 15 can reduce heat loss when the conduction oil circulates in and out of the heat exchanger 3 and the boiler body 1, so that the energy consumption of the boiler can be reduced.
In summary, the present utility model provides a heat transfer oil boiler, by arranging a heat exchanger, and arranging a first oil inlet pipe connected with the heat exchanger and a first oil outlet pipe connected with the heat exchanger and a boiler body at the same time, when the boiler body works, high temperature flue gas can enter the heat exchanger, and after heat transfer oil is used, the heat transfer oil is sent into the heat exchanger through the first oil inlet pipe, and in the heat exchanger, heat contained in the high temperature flue gas can be transferred to low temperature heat transfer oil, and the heat transfer oil can be heated while recovering heat energy contained in the high temperature flue gas; after the heat conducting oil is heated, the heat conducting oil is sent into the boiler body through the first oil outlet pipe, and is further heated to the using temperature in the boiler body. Because the heat conduction oil is heated when being sent into the boiler body, when the heat conduction oil is heated to the use temperature range in the boiler body again, the consumption of the fuel of the boiler body can be reduced, and the energy consumption of the heat conduction oil boiler is reduced.
