Description

Technical Field

[0001] This utility model belongs to the field of atmospheric pressure furnaces, specifically a high-efficiency and energy-saving atmospheric pressure furnace. Background Technology

[0002] Atmospheric furnaces, also known as atmospheric heating furnaces, are one of the important pieces of equipment in oil refineries and petrochemical plants. They are mainly used to heat crude oil, intermediate products, or other process fluids to meet the temperature requirements of subsequent processes. Atmospheric furnaces typically use fuel combustion to generate heat, which is then transferred to the material through the furnace to heat the material to the required temperature. They have a wide range of applications and play an important role in the petrochemical industry.

[0003] After a certain period of operation, atmospheric pressure furnaces will accumulate ash and scale inside. Due to the high thermal resistance of ash and scale, when the furnace is full of ash and scale, it will significantly increase the thermal resistance between the furnace wall and the medium inside the furnace, hindering the transfer of heat. In order to maintain the efficient operation of the atmospheric pressure furnace and extend the service life of the equipment, the furnace body needs to be cleaned and maintained regularly. The common cleaning method is for workers to use handheld sprayers to rinse. However, manual cleaning is not only inefficient, but also increases the workload of workers and poses a risk of workers inhaling dust, which is a certain safety hazard.

[0004] In summary, this utility model provides a high-efficiency and energy-saving atmospheric pressure furnace to solve the above problems. Utility Model Content

[0023] Example 1

[0024] like Figure 1-4 The image shown is the first embodiment of this utility model, which provides a high-efficiency and energy-saving atmospheric pressure furnace, comprising:

[0025] The main unit 1 includes an atmospheric pressure furnace body 101, an opening on the top of the atmospheric pressure furnace body 101, a fixed box 102 fixedly connected to the opening of the atmospheric pressure furnace body 101, a water supply assembly 103 disposed in the inner cavity of the fixed box 102, a rotating nozzle 104 disposed at the bottom of the water supply assembly 103, and a connecting groove 105 disposed at the bottom of the inner cavity of the fixed box 102.

[0026] The adjustment unit 2 includes telescopic rods 201 disposed on both sides of the water supply component 103, an adjustment component 202 disposed on the surface of the water supply component 103, and a sealing component 203 disposed on the surface of the fixed box 102.

[0027] like Figure 1-4 As shown, the atmospheric pressure furnace body 101 serves as the main container for heating and reaction, bearing and transferring heat to the materials inside the furnace. The fixed box 102 provides stable support and installation space for internal components. The water supply assembly 103 delivers water from the high-pressure water pump to the rotary nozzle 104, achieving uniform water distribution and spraying. The rotary nozzle 104 can be an HP500 high-pressure three-dimensional rotary cleaning nozzle, which can spray water evenly into the furnace in a rotating manner, improving the cleaning effect of ash and scale. The connecting groove 105 provides a channel for the water supply assembly 103 and the rotary nozzle 104 to enter the atmospheric pressure furnace body 101. The telescopic rod 201 adopts a multi-tube sleeve design, which is compact, has a large adjustment range, and has good stability. It is used to adjust the vertical position of the rotary nozzle 104 to adapt to cleaning needs at different heights. The adjustment assembly 202 is used to realize the extension and retraction of the telescopic rod 201 and the angle adjustment of the rotary nozzle 104. The sealing assembly 203 realizes the sealing and opening of the connecting groove 105 to prevent heat leakage through the connecting groove 105 when the atmospheric pressure furnace body 101 is operating.

[0028] Example 2

[0029] Reference Figure 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0030] In this embodiment, the water supply assembly 103 includes a fixed pipe 1031 fixedly connected to the top of the fixed box 102, a corrugated pipe 1032 fixedly connected to the bottom of the fixed pipe 1031, and a connecting pipe 1033 fixedly connected to the bottom of the corrugated pipe 1032. The top of the fixed pipe 1031 is connected to the outlet pipe of an external high-pressure water pump, and the bottom of the connecting pipe 1033 is fixedly connected to the top of the rotating nozzle 104.

[0031] The telescopic rod 201 is made up of multiple sleeves connected together, and anti-detachment grooves and anti-detachment blocks are used to limit the movement between every two adjacent sleeves.

[0032] The sealing assembly 203 includes a baffle 2031 slidably connected to the inner cavity of the communicating groove 105, a connecting plate 2032 disposed on the front side of the fixed box 102, the front end of the baffle 2031 penetrating through the inner wall of the fixed box 102 and fixedly connected to the connecting plate 2032, and a cylinder 2033 fixedly connected to the right side of the fixed box 102 by bolts, the output end of the cylinder 2033 being fixedly connected to the back side of the connecting plate 2032.

[0033] like Figure 2-4As shown, the fixed pipe 1031, corrugated pipe 1032, and connecting pipe 1033 work together to achieve flexible guidance and distribution of water flow, improving the utilization efficiency of water resources. The baffle 2031 is a graphite polystyrene board, which serves as a sealing component of the connecting groove 105 and can play a role in heat insulation, preventing heat leakage through the connecting groove 105 when the atmospheric pressure furnace body 101 is in operation. The connecting plate 2032 serves as a connecting component between the baffle 2031 and the cylinder 2033, realizing the driving and control of the baffle 2031 by the cylinder 2033. The cylinder 2033 serves as a driving component of the baffle 2031, and the opening and closing control of the baffle 2031 is realized through the extension and retraction movement of the cylinder 2033.

[0034] Example 3

[0035] Reference Figure 3 and 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0036] In this embodiment, the adjustment component 202 includes a traction ring 2021 fixedly connected to the surface of the connecting pipe 1033, the bottom of the innermost sleeve of the telescopic rod 201 fixedly connected to the top of the traction ring 2021, a fixing block 2022 fixedly connected to both sides of the inner cavity of the fixing box 102, and a fixing ring 2023 fixedly connected to the upper and lower ends of the outermost sleeve surface of the telescopic rod 201, with one end of the fixing ring 2023 fixedly connected to the fixing block 2022.

[0037] The adjustment assembly 202 also includes a dual-axis motor 2024 fixedly connected to the back of the inner cavity of the fixed box 102 via a base, a take-up wheel 2025 connected to the output shaft surfaces on both sides of the dual-axis motor 2024 via a transmission connection, a connecting rope 2026 fixedly connected to the surface of the take-up wheel 2025, one end of the connecting rope 2026 away from the take-up wheel 2025 extending to the inner cavity of the telescopic rod 201 and fixedly connected to the bottom of the innermost sleeve cavity, and a guide wheel 2027 movably connected to the side of the two fixed blocks 2022 close to each other via a bearing, and the connecting rope 2026 slidingly connected to the surface of the guide wheel 2027.

[0038] like Figure 3 and 4As shown, the traction ring 2021 serves as the connecting component between the telescopic rod 201 and the connecting pipe 1033, enabling the telescopic rod 201 to pull and adjust the connecting pipe 1033. The fixing block 2022 and the fixing ring 2023 serve as the fixing and supporting components of the telescopic rod 201, ensuring the stability and accuracy of the telescopic rod 201. The dual-axis motor 2024, the winding wheel 2025, and the connecting rope 2026 work together. Through the driving of the dual-axis motor 2024 and the winding action of the winding wheel 2025, the traction of the connecting rope 2026 and the adjustment of the telescopic rod 201 are achieved. The guide wheel 2027 serves as the guiding component of the connecting rope 2026, ensuring the smooth sliding of the connecting rope 2026 and the accurate adjustment of the telescopic rod 201. The connecting rope 2026 can be made of corrosion-resistant materials such as nylon.

[0039] When a large amount of ash and scale accumulates on the inner wall of the atmospheric pressure furnace body 101 during use and needs to be cleaned, the cylinder 2033 is first activated via the external controller. The output end of the cylinder 2033 extends, cooperating with the connecting plate 2032 to move the baffle 2031 forward until the baffle 2031 no longer obstructs the inner cavity of the connecting groove 105. Then, the dual-shaft motor 2024 is activated. The output shafts on both sides of the dual-shaft motor 2024 drive the two winding wheels 2025 to rotate, causing the winding wheels 2025 to release the connecting rope 2026 wound on the surface. Because the traction ring 2021 is relatively heavy, under the traction of the traction ring 2021, the rotating nozzle 104 passes through the inner cavity of the connecting groove 105 and through the atmospheric pressure furnace body 101. The top opening gradually descends into the inner cavity of the atmospheric pressure furnace body 101. After descending to a certain height, the external water pump is started. The water pump delivers high-pressure water to the inside of the fixed pipe 1031, and then through the corrugated pipe 1032 and the connecting pipe 1033 to the inside of the rotary nozzle 104. Finally, the rotary nozzle 104 sprays high-pressure water onto the inner wall of the atmospheric pressure furnace body 101 to wash away the ash and scale. The rotary nozzle 104 controls the rotation speed through a magnetic damper to form a 360-degree spray pattern for comprehensive cleaning. During the cleaning process, the working height of the rotary nozzle 104 can also be adjusted by starting the dual-axis motor 2024 for thorough rinsing. After rinsing, the wastewater is discharged.
