Description

Technical Field

[0001] The invention relates to the technical field of boilers, and in particular to an intelligent integral skid-mounted heating furnace suitable for petroleum processing. Background Art

[0002] The skid-mounted heating furnace is a special heating equipment, and its structure mainly includes a skid-mounted base, a control cabinet and a heating furnace body. The heating furnace body is fixedly installed on the top of the skid-mounted base, and a control cabinet is fixed on the top of the base on one side of the heating furnace body. The control cabinet is electrically connected to the heating furnace body. In addition, a gas pipeline is provided on one side of the heating furnace body, and a burner is fixed between the gas pipeline and the heating furnace body. The gas pipeline is connected to the heating furnace body through the burner, and a skid-mounted pipeline is fixed on the other side of the heating furnace body. At the same time, the skid-mounted heating furnace uses thermal oil as the heating medium, and transfers heat energy to the heating equipment through forced circulation, and then returns to the heating furnace for reheating. Thermal oil, also known as organic heat carrier or heat transfer oil, has a long history as an intermediate heat transfer medium in industrial heat exchange. The skid-mounted thermal oil furnace uses a direct current boiler based on the forced circulation design concept, generally using coal, oil, and steam as fuel. It can obtain a higher operating temperature at low pressure and has the characteristics of high-precision control of medium operation.

[0003] The authorized patent title is: A horizontal thermal oil heating furnace and method thereof, and the application number is: CN201711338092.4. It is proposed that the existing boiler furnace body is mostly a simple single combustion chamber furnace body. In a single combustion chamber, the flame often sprays from one end to the other. The flame close to the flame nozzle has a high temperature due to sufficient oxygen and fuel, and the flame temperature far away from the flame nozzle is relatively low. The uneven phenomenon of heat at the front and cold at the back is obvious. In addition, it is a single combustion chamber, which is easy to cause incomplete combustion and waste resources. At the same time, due to the existing ordinary cylindrical combustion chamber The heating efficiency of the heating tube is not high, and a lot of energy escapes through the flue gas. However, although the fuel can be fully burned through multiple combustion chambers during the combustion process, its overall purpose is to fully burn the flame and accelerate the temperature rise of the heat transfer oil. However, although the heat transfer oil is heated multiple times during multiple transmissions, some heat will be lost during the transmission process, and it is impossible to control the heating uniformity of each furnace body. When the oil in the high-temperature furnace body flows to the low-temperature furnace body, it will cause a certain amount of heat loss. For this reason, an intelligent integral skid-mounted heating furnace suitable for petroleum processing is needed. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent integral skid-mounted heating furnace suitable for petroleum processing to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an intelligent integral skid-mounted heating furnace suitable for petroleum processing, comprising a carrying box, to which a heating furnace is fixedly connected, a heating furnace is rotatably connected inside the heating furnace, an oil inlet of the heating furnace is connected to an oil inlet pipe, an end of the heating furnace away from the oil inlet pipe is connected to an oil outlet pipe, ends of the oil inlet pipe and the oil outlet pipe away from the heating furnace both pass through the outer wall of the heating furnace and are rotatably connected to the inner wall of the heating furnace via high-temperature resistant sealed bearings, a natural gas inlet pipe and an air inlet pipe are respectively connected inside the heating furnace, air outlets of the natural gas inlet pipe and the air inlet pipe are inclined toward the side wall of the heating furnace, and a plurality of warming structures are connected to the outside of the heating furnace.

The conical tubes arranged in a conical shape can increase the outer wall area of ​​the heating furnace, increase the contact area between the heating furnace and the flame, and improve the heat transfer efficiency. When the flame flows on the surface of the conical tube, it can transfer more heat to the heating furnace, and drive the flame to produce a vortex effect during the rotation of the heating furnace, so that the flame forms a rotating vortex between the plurality of conical tubes, and the turbulence of the flame is increased by the vortex, and the mixing degree of the flame and the air is improved, thereby promoting more complete combustion between the fuel and the air.

[0007] Preferably, a reflux elbow is integrally formed on the outside of each of the plurality of conical tubes, and one end of the reflux elbow away from the conical tube is connected to the heating furnace.

[0008] Preferably, the temperature increasing structure further comprises a plurality of annular tubes, wherein the plurality of annular tubes are integrally formed with the heating furnace, and the annular tubes are coaxially arranged with the heating furnace.

[0009] Preferably, the temperature increasing structure further comprises a plurality of conical grooves, and the plurality of conical grooves are all opened on the outer wall of the heating furnace.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, the natural gas intake pipe and the air intake pipe simultaneously inject natural gas and combustion-supporting air into the interior of the heating furnace, and the natural gas intake pipe and the air intake pipe are ignited by the ignition device inside the heating furnace during the injection process. After the natural gas is ignited, the flame and combustion-supporting air that are continuously ejected can push the heating furnace to rotate inside the heating furnace. When the heating furnace rotates inside the heating furnace, it can not only stir the oil entering the heating furnace, but also make uniform contact with the flame during rotation, so that the flame evenly heats the oil inside the heating furnace and accelerates the heating rate of the oil. At the same time, when the flame is ejected, it can be guided or pushed by the rotating heating furnace, so that it can continue to rotate dynamically, so that more fuel can contact with oxygen, thereby promoting the combustion reaction.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the present invention, after injecting heat transfer oil into the interior of the heating furnace 102 through the oil inlet pipe 103, natural gas is continuously injected into the interior of the heating furnace 101 through the natural gas inlet pipe 105 and ignited, and the heat transfer oil is heated by the continuously output flame. In the process of heating the heat transfer oil, the ejected flame can also drive the heating furnace 102 to rotate. The rotation of the heating furnace 102 can heat the heat transfer oil inside the heating furnace 102 faster and more evenly, and the heating speed is faster. In the rotating process, the heating furnace 102 can also guide the ejected flame to form a rotating motion, so that it burns more fully.

[0029] Embodiment 1: Figure 1 As shown, the present application is an intelligent integral skid-mounted heating furnace suitable for oil processing, including a carrier box 100, to which a heating furnace 101 is fixedly connected, and a heating furnace 102 is rotatably connected inside the heating furnace 101, an oil inlet of the heating furnace 102 is connected with an oil inlet pipe 103, and an end of the heating furnace 102 away from the oil inlet pipe 103 is connected with an oil outlet pipe 104, and ends of the oil inlet pipe 103 and the oil outlet pipe 104 away from the heating furnace 102 both penetrate the outer wall of the heating furnace 101 and are rotatably connected to the inner wall of the heating furnace 101 through high-temperature resistant sealed bearings, the interior of the heating furnace 101 is respectively connected with a natural gas inlet pipe 105 and an air inlet pipe 106, and the air outlets of the natural gas inlet pipe 105 and the air inlet pipe 106 are inclined toward the side wall of the heating furnace 102, and the outside of the heating furnace 102 is connected with multiple warming structures.

[0030] Specifically, during use, the staff connects the oil inlet pipe 103 to the oil injection pipeline, and injects the heat transfer oil into the interior of the heating furnace 102 by opening the valve. After the heat transfer oil enters the interior of the heating furnace 102, natural gas and combustion-supporting air are injected into the interior of the heating furnace 101 through the natural gas inlet pipe 105 and the air inlet pipe 106. An ignition device is installed inside the heating furnace 101. When the ignition device is started, the natural gas entering the heating furnace 101 can be ignited. When the natural gas is ignited, flames will continue to be generated. At the same time, the air injected into the heating furnace 101 through the air inlet pipe 106 can make the flame continue to burn inside the heating furnace 101. When the flame continues to burn inside the heating furnace 101, the heating furnace 102 can be heated, thereby continuously heating the oil inside the heating furnace 102.

[0031] Furthermore, when the natural gas inlet pipe 105 continuously sprays natural gas to form a flame, because the natural gas inlet pipe 105 and the air inlet pipe 106 are inclined, the sprayed flame will continue to spray to the outer wall of the heating furnace 102, and when the flame and the airflow sprayed through the air inlet pipe 106 are continuously transported to the outer wall of the heating furnace 102, the heating furnace 102 itself will be pushed to rotate. When the heating furnace 102 is rotating, the oil inside the heating furnace 102 will roll, and the sprayed flame can contact different outer wall surfaces of the heating furnace 102. By heating the different outer wall surfaces of the heating furnace 102 by the flame, uniform heating of the inside of the heating furnace 102 can be achieved. At the same time, the oil rolling phenomenon generated during the rotation of the heating furnace 102 can further enhance the heating speed of the heat transfer oil.

[0032] Furthermore, during the rotation of the heating furnace 102, because the flame ejected through the natural gas inlet pipe 105 directly contacts the outer wall of the heating furnace 102, it will interact with the flame during the continuous rotation of the heating furnace 102, and the surface of the heating furnace 102 will guide or push the flame to form a rotating motion. This rotating flame helps to increase the surface area of ​​the flame, allowing more fuel to contact oxygen, thereby promoting the combustion reaction. In addition, the rotating flame may also generate a certain amount of airflow disturbance, which helps to mix the unburned fuel and oxygen more evenly, further improving the combustion efficiency.

[0033] like Figure 2-Figure 4As shown, the exterior of the heating furnace 102 is integrally formed with a plurality of extension pieces 500. The arrangement of the plurality of extension pieces 500 can form a fire baffle for the heating furnace 102 when the natural gas inlet pipe 105 and the air inlet pipe 106 respectively eject flames and air. When the ejected flames and air are blocked, the thrust of the flames and air will be concentrated on the plurality of extension pieces 500. Furthermore, the arrangement of the plurality of extension pieces 500 can assist the flames and air in continuously pushing the heating furnace 102.

[0034] like Fig. 9 As shown, a plurality of arc boxes 800 are integrally formed on the outside of the heating furnace 102 , and a moving ball 801 is movably connected inside the arc box 800 .

[0035] Specifically, in order to further speed up the rotation speed of the heating furnace 102 inside the heating furnace 101, the heating furnace 102 will drive multiple arc boxes 800 to move in a circular direction around the heating furnace 102 during its rotation. When the multiple arc boxes 800 are moving, the moving ball 801 inside the arc box 800 will also move inside the arc box 800 due to the change in gravity. When the moving ball 801 moves inside the arc box 800, the moving potential energy of the moving ball 801 during the movement is converted into kinetic energy, thereby assisting and accelerating the rotation force of the heating furnace 102, increasing the rotation speed of the heating furnace 102 inside the heating furnace 101, avoiding the heating furnace 102 rotating too slowly, resulting in the flame heating one position of the heating furnace 102 for a long time, and accelerating the heating speed of the heating furnace 102.

[0036] Specifically, when the heating furnace 102 is rotating, the rotation of the cylinder of the heating furnace 102 increases its heat transfer area, and its effective heat transfer area increases by 1.2 times compared with a fixed cylinder. As the heat transfer area increases, the heating speed of the heat transfer oil is further increased.

[0037] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the prior art, in the present embodiment, the flame ejected through the natural gas inlet pipe 105 can drive the heating furnace 102 to rotate, and during the rotation of the heating furnace 102, not only can the heating area of ​​the oil inside the heating furnace 102 be increased, but the oil inside the heating furnace 102 can also be turned over by rotation, so that the heating of the oil is more uniform, and the rotating heating furnace 102 can also drive the ejected flame to rotate, and the rotating flame increases the contact area between the flame and the fuel, thereby improving the combustion effect of the flame and making the flame burn more fully.

[0038] Embodiment 2: Considering that the efficiency of increasing the heating speed of the heat transfer oil by simply rotating the heating furnace 102 is low during use, and the situation when the flame is driven by the rotation of the heating furnace 102 to form a rotary combustion is limited by factors such as the shape and rotation speed of the heating furnace 102, so the success rate of the flame in successfully forming a rotary combustion is low, and the low success rate will affect the heating speed of the heat transfer oil. In view of the above technical problems, the present application proposes a temperature increase structure to solve the above technical problems, specifically:

[0039] like Figure 2 As shown, the temperature increasing structure includes a plurality of tapered tubes 200, and the plurality of tapered tubes 200 are integrally formed on the outside of the heating furnace 102. The tapered tubes 200 arranged in a tapered shape can increase the outer wall area of ​​the heating furnace 102, increase the contact area between the heating furnace 102 and the flame, and improve the heat transfer efficiency. When the flame flows on the surface of the tapered tube 200, it can transfer more heat to the heating furnace 102, and drive the flame to produce a vortex effect during the rotation of the heating furnace 102, so that the flame forms a rotating vortex between the plurality of tapered tubes 200, and the turbulence of the flame is increased by the vortex, and the mixing degree of the flame and the air is improved, thereby promoting a more complete combustion between the fuel and the air.

[0040] Specifically, during use, multiple tapered tubes 200 are arranged outside the heating furnace 102, and the arrangement of multiple tapered tubes 200 will increase the outer wall area of ​​the heating furnace 102. By increasing the outer wall area of ​​the heating furnace 102, the contact area with the flame is increased, and the arrangement of the tapered tubes 200 increases the surface area in contact with the flame, thereby improving the heat transfer efficiency. When the flame flows on the surface of the tapered tubes 200, more heat can be transferred to the heating furnace 102, which helps to improve its heating effect.

[0041] Furthermore, the design of the tapered tubes 200 also generates a vortex effect, so that the flame forms a rotating vortex between the multiple tapered tubes 200. This vortex helps to increase the turbulence of the flame and improve the mixing degree of the flame and air, thereby promoting more complete combustion.

[0042] Furthermore, a plurality of conical tubes 200 are arranged in a staggered manner, not shown in the figure, to ensure that the flame can form a stable rotational motion on the outer wall of the rotating cylinder, and to avoid a single arrangement causing the flame to be unable to produce a sufficient rotation effect.

[0043] Furthermore, the heating furnace 102 is divided into an upper quarter, left and right quarters, and a lower quarter, and a plurality of conical tubes 200 are connected to the upper quarter, and the plurality of conical tubes 200 are located above the heating furnace 102 after the heating furnace 102 is completely rotated, so that the conical tubes 200 are always facing upward. When the conical tubes 200 are always facing upward, it is ensured that the oil entering the conical tube 200 will not be partially retained in the conical tube 200 during transportation through the oil outlet pipe 104. When the conical tube 200 is located in the upper position, the oil in the conical tube 200 will fall back into the internal space of the heating furnace 102 due to gravity, thereby avoiding a large amount of oil remaining in the conical tube 200.

[0044] Furthermore, each conical tube 200 will extend the area ratio of the heating furnace 102 by 3%, and in the case of multiple conical tubes 200, an additional area of ​​3%+n will be formed. In addition, when the conical tube 200 increases the additional area, oil will enter the interior of the conical tube 200 when the heating furnace 102 rotates. The oil entering the conical tube 200 will form an additional heating point inside the heating furnace 101, and the heating speed will be faster.

[0045] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment one, in this embodiment, the outer wall area of ​​the heating furnace 102 is effectively increased by the arrangement of multiple conical tubes 200, thereby expanding the contact area with the flame, so that when the flame flows on the surface of the conical cylinder, it can transfer more heat to the rotating cylinder, thereby improving the overall heat transfer efficiency and accelerating the heating process of the heat transfer oil. At the same time, the arrangement of the conical tubes 200 also generates a vortex effect, so that the flame forms a rotating vortex between the multiple conical tubes. This vortex not only increases the turbulence of the flame, improves the mixing degree of the flame and the air, and promotes more complete combustion, but also further enhances the heat exchange effect between the flame and the rotating cylinder. The staggered arrangement of the multiple conical tubes 200 ensures that the flame can form a stable rotational motion on the outer wall of the rotating cylinder, thereby improving the success rate of the flame rotation combustion.

[0046] Embodiment 3: Considering that after the multiple conical tubes 200 form additional heating points, the oil inside the conical tube 200 has a higher heat after heating than the oil retained in the heating furnace 102, and this part of the oil with higher heat may remain in the conical tube 200 due to the centrifugal force generated during the rotation of the heating furnace 102, and cannot flow back to the inside of the heating furnace 102 as a whole, and cannot replace other oil with lower heat for fixed-point heating. In view of the above technical problems, the present application proposes the following technical solutions, which are specifically:

[0047] like Figure 2As shown, a return elbow 300 is integrally formed on the outside of the plurality of tapered tubes 200 , and one end of the return elbow 300 away from the tapered tube 200 is connected to the heating furnace 102 .

[0048] Specifically, during use, multiple reflux elbows 300 are arc-shaped and connected to the inside of the conical tube 200 and the heating furnace 102 respectively. When the heating furnace 102 rotates, part of the heat transfer oil will enter the conical tube 200 for fixed-point heating, and during the continuous rotation of the heating furnace 102, the oil inside the conical tube 200 will be re-transported into the heating furnace 102 through the pipeline passage of the reflux elbow 300. Therefore, during the rotation of the heating furnace 102, a large amount of oil with a higher temperature in the conical tube 200 can be directly transported into the heating furnace 102 to form a heat flow circulation, thereby avoiding the situation where part of the oil remains in the conical tube 200 and cannot flow back to the heating furnace 102.

[0049] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment 2, in this embodiment, through the connectivity of the arc-shaped connecting pipe return elbow 300, these oils with higher temperatures can be smoothly transported back to the interior of the rotating cylinder through the pipeline, thereby realizing the circulation of heat flow. The circulation of heat flow improves the overall heating efficiency. Since the oil temperature inside the conical cylinder is relatively high, when these oils flow back to the interior of the rotating cylinder through the arc-shaped connecting pipe, they will mix with the oil with lower temperature inside the heating furnace 102, thereby increasing the temperature of the overall oil. Through circulating heating, the heat can be more evenly distributed in the entire heat transfer oil system, thereby accelerating the heating process of the heat transfer oil.

[0050] Embodiment 4: Considering that the outer wall surfaces of the tapered tube 200 and the return elbow 300 are both curved surfaces, the flame is sprayed upward from the bottom of the heating furnace 102. Therefore, when the flame is just sprayed, it will not be able to reach part of the curved surface of the tapered tube 200 and the return elbow 300 in time, resulting in a heating blind area. In view of the above technical problems, the present application once again proposes a temperature increase structure to solve the above technical problems, specifically:

[0051] like Figure 3-Figure 4 As shown, the temperature increasing structure further includes a plurality of annular tubes 400 , and the plurality of annular tubes 400 are integrally formed with the heating furnace 102 , and the annular tubes 400 and the heating furnace 102 are arranged coaxially.

[0052] Specifically, during use, the annular tube 400 is in the shape of a knife edge, with inclined cross sections on both sides. When the flame erupts onto the annular tube 400, it will be directly separated by the annular tube 400. After the flame is separated, it will directly heat the cross sections on both sides of the annular tube 400. At the same time, during the continuous rotation process, the heat transfer oil inside the heating furnace 102 will enter the inner cavity of the annular tube 400. When the flame continuously heats the two cross sections of the annular tube 400, it can continuously transfer heat to the inner cavity of the annular tube 400, thereby accelerating the heating speed of the heat transfer oil. At the same time, the annular tube 400 is set to a continuous arc cross section, which increases the heating area of ​​the heating furnace 102 as a whole.

[0053] like Figure 4 As shown, considering that when the outside of the heating furnace 102 is arranged with multiple annular tubes 400, the cross-sections at both ends of the annular tubes 400 are triangular. Although the triangular cross-sections can drive the flame to flip upward to form an annular flame, the integrity of the fuel combustion is improved, but the end face of the annular tube 400 is small, the ability to drive the flame is poor, and the annular tube 400 has only one cross-section. Each rotation cycle of the heating furnace 102 can only drive the flame to flip once, so that the ability of the flame to form an annular flame is poor. The outer wall of the annular tube 400 is fixedly connected with multiple arc plates 900, and through the arrangement of multiple arc plates 900, multiple arc-shaped fire-blocking surfaces are formed on the outer wall of the annular tube 400, so that during the rotation of the annular tube 400, the arc plates 900 continuously flip the flame and fuel upward, so that the flame continues to form an annular flame inside the heating furnace 102, so that the fuel burns more fully, and multiple blade-shaped annular tubes 400 can effectively reduce the phenomenon of heating blind spots.

[0054] like Figure 8 As shown, in addition to providing a plurality of annular tubes 400 , the present application further provides a temperature increasing structure, which further includes a plurality of conical grooves 700 , and the plurality of conical grooves 700 are all opened on the outer wall of the heating furnace 102 .

[0055] Specifically, a plurality of conical grooves 700 are formed inwardly from the outside of the heating furnace 102, so that the heating furnace 102 is shaped like a plum blossom as a whole. When the heating furnace 102 is rotated by the promotion of the flame, the flame will continuously enter the conical groove 700. Due to the shaping of the conical groove 700, part of the inner wall of the heating furnace 102 cuts into the oil in a knife-like manner, so that the oil located at the center of the heating furnace 102 can be heated during the continuous rotation. At the same time, when the flame enters the conical groove 700, it will be brought to an obliquely upward direction by the rotating heating furnace 102. When the flame rotates driven by the conical groove 700, it can assist in the formation of the rotating flame and enhance the full combustion rate of the fuel.

[0056] like Figure 1As shown, a protective plate 600 is hinged on the outside of the carrier box 100, a suction fan 601 is installed on the outside of the protective plate 600, an air inlet of the suction fan 601 is connected to a hose 602, and one end of the hose 602 away from the suction fan 601 is connected to the heating furnace 101.

[0057] Specifically, during use, when the flame continues to burn inside the heating furnace 101, the smoke generated by the burning flame will be sucked into the interior of the carrier box 100 through the hose 602 under the drive of the suction fan 601. A purification device is installed inside the carrier box 100, and the outside of the carrier box 100 is connected to a dedicated smoke exhaust port. After the smoke is purified, it is discharged through the dedicated smoke exhaust port.

[0058] Furthermore, when the smoke enters the interior of the carrier box 100 , the heat inside the smoke can be transferred to the outside of the heating furnace 101 , and the heat inside the smoke can be conducted again, thereby reducing the waste of heat in the smoke.

[0059] The technical solutions in the above-mentioned embodiments of the present application have at least the following technical effects or advantages: relative to the third embodiment, in the present embodiment, by integrally forming a plurality of annular tubes 400 on the heating furnace 102, precise separation of the flame and heating of the cross section are achieved. When the flame erupts, it is effectively separated by the blade-like cross section of the annular tube 400, directly heating the inclined cross sections on both sides thereof, which not only improves the heat utilization rate, but also expands the overall heating area. At the same time, the inner cavity design of the annular tube 400 enables the heat transfer oil to quickly absorb and transfer heat, thereby significantly accelerating the heating speed of the heat transfer oil, and effectively reducing the occurrence of heating blind spots at the beginning of the flame eruption stage.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
