[0001] The utility model relates to the technical field of heat recovery, and more specifically, to a heat-conducting oil furnace with a heat recovery mechanism. Background Art
[0002] A heat-conducting oil furnace is also called an organic heat carrier furnace, commonly known as a heat-conducting oil boiler, and its official name is a hot oil furnace. It is a new type of heat energy equipment that uses coal, oil, or gas as fuel and heat-conducting oil as the circulating medium for heat supply. A heat-conducting oil furnace refers to a new type of heat energy conversion equipment with high-temperature heat-conducting oil as the heat-carrying working medium. Usually, the capacity of the furnace is also expressed in "MW" (megawatt), and the old unit is also expressed in "10,000 kilowatts / hour" or "10,000 kcal / h", that is, "104 kcal / h". The advantage of a heat-conducting oil furnace lies in its high temperature and low pressure, stable operation, and thus it is widely used.
[0003] The heat-conducting oil furnace is widely used in various industrial fields that require heating. When the flue gas generated after the fuel combustion is discharged through the chimney, the temperature is generally about 170°C, and some are even as high as 300°C. However, most of the existing heat-conducting oil furnaces cannot recover and utilize the heat of the flue gas, resulting in energy waste. Summary of the Utility Model

[0006] An exhaust pipe is communicated with the heat-conducting oil furnace body;
[0007] The hot air mechanism is arranged on one side of the heat-conducting oil furnace body. The hot air mechanism is used to heat air by using flue gas. The hot air mechanism includes an intake pipe, a conversion box, an outlet pipe, a ventilation box, a fan, and an outlet duct. One end of the intake pipe is communicated with the exhaust pipe, and the other end of the intake pipe is communicated with the conversion box.

[0025] Referring to Figures 1 to 3 , the present invention provides a technical solution: a heat-conducting oil furnace with a heat recovery mechanism, including the main body 1 of the heat-conducting oil furnace, a hot air mechanism, and a hot water mechanism;
[0026] An exhaust pipe 2 is connected to the main body 1 of the heat-conducting oil furnace, and the flue gas is discharged through the exhaust pipe 2;
[0027] The hot air mechanism is arranged on one side of the heat-conducting oil furnace body 1. The hot air mechanism is used to heat air by using flue gas. The hot air mechanism includes an intake pipe 3, a transducer box 4, an exhaust pipe 5, a ventilation box 6, a fan 7 and an air outlet pipe 8. One end of the intake pipe 3 is communicated with the exhaust pipe 2, and the other end of the intake pipe 3 is communicated with the transducer box 4. The transducer box 4 can be made of metal with good heat conductivity. The side of the transducer box 4 away from the intake pipe 3 is communicated with the exhaust pipe 5. The outside of the transducer box 4 is sleeved with a ventilation box 6. The intake pipe 3 and the exhaust pipe 5 both penetrate through the side wall of the ventilation box 6. One end of the ventilation box 6 is communicated with the air outlet of the fan 7, and the other end of the ventilation box 6 is communicated with the air outlet pipe 8;
[0028] Such as Figure 1 and Figure 2 , the flue gas discharged from the exhaust pipe 2 enters the transducer box 4 through the intake pipe 3. The heat carried by the flue gas can be dissipated to the ventilation box 6 through the transducer box 4. The flue gas after losing heat is discharged through the exhaust pipe 5. By blowing air into the ventilation box 6 through the fan 7, the hot air in the ventilation box 6 will be blown out through the air outlet pipe 8, so as to obtain hot air for use. For example, heating the indoor in winter, effectively recycling the heat of the flue gas and making full use of energy.
[0029] The hot water mechanism is arranged on one side of the heat-conducting oil furnace body 1. The hot water mechanism is used to heat water by using flue gas.
[0030] Specifically, a plurality of baffles 9 are fixedly connected inside the transducer box 4. Such as Figure 2 , the plurality of baffles 9 restrict the flow direction of the flue gas. The flue gas can only be discharged through the exhaust pipe 5 after bypassing the plurality of baffles 9, so that the flue gas stays in the transducer box 4 for a longer time, facilitating the full dissipation of the heat in the flue gas to the ventilation box 6.
[0031] Specifically, a plurality of fins 10 are fixedly connected to the side wall of the transducer box 4. Such as Figure 2 , the plurality of fins 10 can also accelerate the dissipation of the heat in the flue gas to the ventilation box 6.
[0032] Specifically, the hot water mechanism includes a three-way valve 11, a spiral pipe 12 and a water tank 13. The intake port of the three-way valve 11 is communicated with the exhaust pipe 2. One outlet of the three-way valve 11 is communicated with the intake pipe 3, and the other outlet of the three-way valve 11 is communicated with one end of the spiral pipe 12. The three-way valve 11 can communicate the exhaust pipe 2 with the intake pipe 3, or communicate the exhaust pipe 2 with the spiral pipe 12. The outside of the spiral pipe 12 is sleeved with the water tank 13. Both ends of the spiral pipe 12 penetrate through the side wall of the water tank 13. The spiral pipe 12 can be made of metal with good heat conductivity;
[0033] Such as Figure 1 and Figure 3, the exhaust pipe 2 is connected to the spiral pipe 12 through a three-way valve 11, and the flue gas in the exhaust pipe 2 will enter the spiral pipe 12. The flue gas in the spiral pipe 12 can heat the water in the water tank 13, effectively recycling the heat of the flue gas, and the use of the hot air mechanism or the hot water mechanism can be selected according to needs.
[0034] Specifically, a water inlet pipe 14 is connected to the upper end of the water tank 13, and water is injected into the water tank 13 through the water inlet pipe 14. A drain pipe 15 is connected to the lower end of the water tank 13. A valve 16 is installed on the drain pipe 15, and the water in the water tank 13 is discharged through the drain pipe 15, and the on-off of the drain pipe 15 can be controlled by the valve 16.
[0035] Working principle: The flue gas discharged from the exhaust pipe 2 enters the energy conversion box 4 through the intake pipe 3. The heat carried by the flue gas can be dissipated into the ventilation box 6 through the energy conversion box 4. The flue gas after losing heat is discharged through the outlet pipe 5. By blowing air into the ventilation box 6 through the fan 7, the hot air in the ventilation box 6 will be blown out through the outlet duct 8, so as to obtain hot air for use, effectively recycling the heat of the flue gas and making full use of energy.
