Description

Technical Field

[0001] This utility model relates to the technical field of heating furnace equipment, specifically an organic heat carrier heating furnace. Background Technology

[0002] Organic heat carrier coal-fired heaters use coal (and now also gas or oil) as fuel, and heat transfer oil as the heat carrier. They utilize a circulating oil pump for forced liquid-phase circulation to transfer heat energy to the heat-using equipment before returning for reheating and recirculation. These specialized industrial furnaces are characterized by achieving high operating temperatures at relatively low operating pressures, a wide heating range (250–350℃), stable heating, and precise temperature control. Thermal efficiency remains at optimal levels under varying loads. They are suitable for drying and heating systems in various industries, including chemical, petrochemical, plastics, rubber, textiles, printing, wood, food, papermaking, printing, building materials, and transportation.

[0019] The following embodiments will be described in detail with reference to the accompanying drawings. In the drawings and description, similar or identical parts are referred to by the same reference numerals. Furthermore, in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of the utility model.

[0020] Example

[0021] Please see Figures 1-3 In this embodiment of the utility model, an organic heat carrier heating furnace includes a furnace body 1. The furnace body 1 has an opening, and a top cover 2 is provided inside the opening. The top cover 2 is fixed to the furnace body 1 by fixing bolts 201. A sealing gasket is also provided at the bottom of the top cover 2. The fixing bolts 201 and the sealing gasket are important for improving the sealing performance of the top cover 2 to the furnace body 1, thereby improving the sealing performance of the device to a certain extent, reducing the leakage of flue gas and heat, and preventing the reduction of the device's operating efficiency. This ensures the efficiency of the device. In addition, the fixing bolts 201 facilitate the subsequent maintenance and upkeep of the internal components of the device by the staff, thus ensuring the efficiency of the device.

[0022] The furnace body 1 is equipped with a spiral bend 3. The left end of the spiral bend 3 is provided with an oil inlet 4, and the right end of the spiral bend 3 is provided with an oil outlet 5. The oil outlet 5 is connected to the heating device. Under the action of the oil inlet 4, the spiral bend 3 and the oil outlet 5, the circulation of heat transfer oil is realized, so that the heat transfer oil can realize the function of heat transfer and heating, thereby meeting the needs of the device.

[0023] A flue 6 is provided at the bottom of the furnace body 1, and a baffle plate 7 is provided inside the furnace body 1 above the flue 6. The baffle plate 7 is evenly provided with a plurality of through holes 701. Under the action of the baffle plate 7 and the through holes 701, the flue gas entering the furnace body 1 from the flue 6 can be more evenly contacted with the spiral bend tube 3, thereby improving the heating efficiency of the spiral bend tube 3 and ensuring the heating efficiency of the heat transfer oil. The baffle plate 7 is raised and installed inside the furnace body 1 to ensure the quality of use of the baffle plate 7.

[0024] The top cover 2 is also provided with a smoke collection cover 14, a smoke outlet pipe 8 is provided on the smoke collection cover 14, and a filter sleeve 9 is provided on the smoke outlet pipe 8. Under the action of the filter sleeve 9, impurities and toxic substances in the smoke can be filtered, reducing the occurrence of direct emission into the air and causing pollution and damage to the environment. A smoke exhaust pipe 10 is provided at the smoke outlet end on the right side of the filter sleeve 9, and the smoke exhaust pipe 10 can be used to better exhaust the smoke.

[0025] A water tank 11 is also provided on the top cover 2 outside the smoke collection cover 14. The water tank 11 is equipped with a water inlet pipe 12, which allows water to be added for use. A water valve 1201 is also provided on the water inlet pipe 12, facilitating the addition of water to the water tank 11 by the operator. A return pipe 13 is also provided on the water tank 11, with its outlet connected to the furnace body 1. When flue gas enters through the flue 6... After entering the furnace body 1, its heat will heat the spiral bend tube 3, but the heat cannot be completely absorbed by the spiral bend tube 3. At this time, the heat will be concentrated under the action of the smoke collection cover 14, thereby heating the water in the water tank 11. After heating, the water forms steam and enters the furnace body 1 through the return pipe 13, thereby continuing to heat the spiral bend tube 3. In conjunction with the smoke outlet pipe 8, it reduces the accumulation of moisture inside the furnace body 1, ensuring the heating efficiency and quality of the device for the spiral bend tube 3.

[0026] In use, after setting the device in a suitable location, connect the oil inlet 4 to the oil pump and the oil outlet 5 to the heating device. At this time, the flue gas is introduced into the furnace body 1 through the flue 6, so that the heat in the flue gas heats the heat transfer oil in the spiral bend 3, ensuring that the heat transfer oil can meet the needs of subsequent heating. The flue gas after the heat is used up will enter the filter sleeve 9 through the flue pipe 8. Under the action of the filter sleeve 9, the toxic substances in the flue gas can be filtered, reducing its impact on the environment. The filtered flue gas is discharged through the exhaust pipe 10. At this time, the operator can open the water valve 1201 and add water to the water tank 11 through the water inlet pipe 12. Under the action of the waste heat of the flue gas, the water in the water tank 11 is heated. The heated water is evaporated to form steam. The steam flows back to the furnace body 1 through the return pipe 13, thereby heating the spiral bend 3 and realizing the function of waste heat recovery. At the same time, because the inside of the furnace body 1 is in a high-temperature state, water vapor cannot remain in the furnace body 1, thus ensuring the efficiency of the device.
