[0024] Please refer to Figure 1 , Figure 1 , which is a schematic structural diagram of a heat-conducting oil boiler in an embodiment of the present invention. The heat-conducting oil boiler includes a heat exchange component 100 and a heating component 200. Among them, the heat exchange component 100 includes a first oil supply pipe 110, a second oil supply pipe 120, a first heat exchanger 130, and a second heat exchanger 140. The first oil supply pipe 110 is connected to the first heat exchanger 130, and the second oil supply pipe 120 is connected to the second heat exchanger 140. The heating component 200 includes a burner 210 and a waste gas pipe 220. The burner 210 generates heat through combustion and is connected to the first heat exchanger 130. The waste gas pipe 220 discharges the waste gas generated by the burner 210 and is connected to the second heat exchanger 140.

[0025] In this embodiment, the heat generated by the burner 210 is transferred to the heat-conducting oil in the first oil supply pipe 110 through the first heat exchanger 130, and the heat of the flue gas in the waste gas pipe 220 is transferred to the heat-conducting oil in the second oil supply pipe 120 through the second heat exchanger 140, so that the heat generated by the combustion of the burner 210 can be fully absorbed. By using the heat-conducting oil boiler provided by the present utility model, the heat entrained in the flue gas can be effectively absorbed, avoiding waste of energy.

[0026] In some of these embodiments, the heat transfer oil boiler aggregation assembly 300 further includes an oil delivery pipe and a tee joint 320. The tee joint 320 is respectively connected to the first oil supply pipe 110, the second oil supply pipe 120, and the oil delivery pipe.

[0027] In this embodiment, the heat transfer oil in the first oil supply pipe 110 and the second oil supply pipe 120 is introduced into the tee joint 320, so that the heat transfer oil in the first oil supply pipe 110 and the second oil supply pipe 120 enters the oil delivery pipe together and is finally transported to the reaction kettle via the oil delivery pipe, thereby adjusting the reaction temperature of the reaction kettle.

[0028] In some of these embodiments, the aggregation assembly 300 further includes a stirring impeller 330. The stirring impeller 330 is installed at one end of the oil delivery pipe close to the tee joint 320, and is used to stir the heat transfer oil in the oil delivery pipe.

[0029] In this embodiment, the stirring impeller 330 is installed at one end of the oil delivery pipe close to the tee joint 320, so that the heat transfer oil exported by the tee joint 320 can be stirred by the stirring impeller 330. Furthermore, the heat transfer oils in the first oil supply pipe 110 and the second oil supply pipe 120 are mixed with each other, making the temperature of the heat transfer oil in the oil delivery pipe uniform.

[0030] In some of these embodiments, the aggregation assembly 300 further includes a first check valve 340 and a second check valve 350. The first check valve 340 is installed at one end of the first oil supply pipe 110 close to the tee joint 320, and the second check valve 350 is installed at one end of the second oil supply pipe 120 close to the tee joint 320.

[0031] In this embodiment, installing the first check valve 340 and the second check valve 350 on the first oil supply pipe 110 and the second oil supply pipe 120 can effectively prevent the heat transfer oil in the oil delivery pipe from flowing back into the first oil supply pipe 110 and / or the second oil supply pipe 120.

[0032] In some of these embodiments, the aggregation assembly 300 further includes a third thermometer 360. The third thermometer 360 is used to detect the temperature of the heat transfer oil in the oil delivery pipe.

[0033] In some of these embodiments, the heat exchange assembly 100 includes a first thermometer 150 and a second thermometer 160. The first thermometer 150 is used to detect the temperature of the heat transfer oil in the first oil supply pipe 110, and the second thermometer 160 is used to detect the temperature of the heat transfer oil in the second oil supply pipe 120.

[0034] On the basis of the above embodiments, in some of these embodiments, the first thermometer 150 is arranged between the first heat exchanger 130 and the tee joint 320, and the second thermometer 160 is arranged between the second heat exchanger 140 and the tee joint 320.

[0035] It can be understood that the temperature of the heat-conducting oil at various locations can be grasped through the first thermometer 150, the second thermometer 160, and the third thermometer 360, so as to adjust the firepower of the burner 210, making the temperature of the heat-conducting oil finally leading to the reaction kettle meet the usage requirements.

[0036] In some of these embodiments, the heat exchange assembly 100 further includes an oil supply member 170, and the oil supply member 170 conveys the heat-conducting oil to the first oil supply pipe 110 and the second oil supply pipe 120 respectively.

[0037] It should be noted that as long as the implementation manner of the oil supply member 170 that can introduce the heat-conducting oil into the first oil supply pipe 110 and the second oil supply pipe 120 is feasible. Generally, the oil supply member 170 should include an oil storage tank and an oil pump. The oil storage tank is used to recover the heat-conducting oil flowing back from the reaction kettle, and the oil pump is used to pump the heat-conducting oil in the oil storage tank to the first oil supply pipe 110 and the second oil supply pipe 120.

[0039] In this embodiment, in the initial stage of the operation of the burner 210, the heat carried by the exhaust gas is less, and there is no need to recover this part of the heat. The second oil supply pipe 120 can be closed through the cut-off valve. After the burner 210 has been operating for a period of time, a large amount of heat is carried by the exhaust gas. At this time, the second oil supply pipe 120 can be opened to recover the heat in the exhaust gas.

[0040] In some of these embodiments, the heating assembly 200 further includes a filter member 230, and the filter member 230 is arranged between the burner 210 and the second heat exchanger 140, and is used to filter the solid impurities in the exhaust gas in the exhaust gas pipe 220, so as to prevent too many impurities from accumulating in the second heat exchanger 140.

[0041] For a better understanding of the present invention, the following combines Figure 1 to describe the technical solution of the present invention in detail:

[0042] The heat generated by the burner 210 is transferred to the heat-conducting oil in the first oil supply pipe 110 through the first heat exchanger 130, and the heat of the flue gas in the waste gas pipe 220 is transferred to the heat-conducting oil in the second oil supply pipe 120 through the second heat exchanger 140, so that the heat generated by the combustion of the burner 210 can be fully absorbed. The stirring impeller 330 is installed at one end of the oil delivery pipe close to the three-way joint 320, so that the heat-conducting oil led out by the three-way joint 320 can be stirred by the stirring impeller 330, and then the heat-conducting oil in the first oil supply pipe 110 and the second oil supply pipe 120 is mixed with each other, making the temperature of the heat-conducting oil in the oil delivery pipe uniform. Finally, it is transported to the reaction kettle through the oil delivery pipe, thereby adjusting the reaction temperature of the reaction kettle. By using the heat-conducting oil boiler provided by the present utility model, the heat entrained in the flue gas can be effectively absorbed, avoiding waste of energy.
