Description

Technical Field

[0001] This utility model relates to the field of organic heat carrier boiler technology, specifically to an organic heat carrier boiler with a residual heat recovery structure. Background Technology

[0002] Organic heat carrier boilers refer to a new type of heat energy conversion equipment that uses high-temperature heat transfer oil as the heat transfer medium. Therefore, organic heat carrier boilers are also called heat transfer oil boilers. They use coal, heavy oil, light oil, combustible gas and other combustible materials as fuel, and heat transfer oil as the heat carrier. They use a circulating oil pump to force liquid phase circulation to transfer heat energy to the heat-using equipment and then return to the reheating once-through special industrial furnace. However, when the boiler is in use, a large amount of heat will escape from the exhaust pipe, which causes a large amount of still high-temperature gas to be directly discharged, resulting in low energy utilization. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an organic heat carrier boiler with a residual heat recovery structure. This solves the problem mentioned in the background art where a large amount of heat escapes from the exhaust pipe during combustion, resulting in the direct discharge of a large amount of still-high-temperature gas and low energy utilization.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an organic heat carrier boiler with a waste heat recovery structure, comprising a waste heat recovery structure, wherein an organic heat carrier boiler structure is installed on one side of the waste heat recovery structure;

[0005] The residual heat recovery structure includes a recovery box with a preheating chamber at the bottom, and a through-hole plate is welded and fixed inside the recovery box at the top, while a hollow U-shaped tube is fixed at the bottom of the through-hole plate.

[0006] A connecting plate is welded and fixed inside the lower part of the recycling bin, and a heat-insulated observation baffle is installed at the bottom of the recycling bin by hinge. At the same time, a thermometer and a barometer are respectively embedded on one side of the recycling bin.

[0007] By adopting the above technical solution, the rotation opening and closing is achieved through the setting of a heat-insulated observation baffle.

[0008] Preferably, a connecting cover is welded and fixed above the through-hole plate, and a cavity conveying pipe is embedded and installed on both sides of the connecting cover through the recycling box, while one end of the cavity conveying pipe is embedded and extends through the interior of the preheating chamber.

[0009] By adopting the above technical solution, the connecting cover is used to achieve the function of wrapping and installation.

[0010] Preferably, a cavity heating block is fixedly installed inside the preheating chamber, and the cavity heating block is embedded and connected to one end of the cavity conveying pipe. An inlet valve pipe and an outlet valve pipe are respectively embedded and installed on one side of the recovery box.

[0011] By adopting the above technical solution, the cavity heating block is used to achieve heat filling and utilization.

[0012] Preferably, the mechanical heat carrier boiler structure includes a mechanical heat carrier boiler body as the main body, and a fan is installed in the mechanical heat carrier boiler body through an air outlet pipe. At the same time, one end of the fan is connected to one end of a connecting conveying pipe, and the other end of the connecting conveying pipe extends through the top of the recycling box and extends into the inside of the recycling box and is welded and fixed to the connecting cover.

[0013] By adopting the above technical solution, the installed fan can achieve the function of extraction and transportation.

[0014] Preferably, the hollow U-shaped tubes are provided in 3 groups, and each group of hollow U-shaped tubes is provided with 13 tubes arranged in a ring array.

[0015] By adopting the above technical solution, the hollow U-shaped tube is used to achieve matching installation and fixation.

[0016] Preferably, one set of cavity delivery pipes is provided, and the cavity delivery pipes are symmetrically arranged about the axis of the cavity heating block.

[0017] By adopting the above technical solution, the hollow delivery pipe is used to achieve the function of embedding and conveying at both ends.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the organic heat carrier boiler with a waste heat recovery structure,

[0019] (1) This case solves the problem of a large amount of heat escaping from the exhaust pipe during boiler combustion by setting up a residual heat recovery structure, which results in a large amount of still high-temperature gas being directly discharged, leading to low energy utilization. When the heat carrier boiler is working, the heat discharged is transported to the inside of the collection box and then to the cavity U-shaped tube and the cavity conveying pipe. When the heat is transported to the cavity U-shaped tube and the cavity conveying pipe, the liquid injected into the upper part of the recovery box is heated. The heat transported to the cavity heating block is used to heat the cavity heating block. The heated cavity heating block is used to preheat materials, food or other objects. By diverting and transporting the discharged heat for recycling, the waste of heat is avoided.

[0020] (2) By setting up a heat carrier boiler structure, the above problems are solved. When heat is discharged, it is transported to the inside of the connecting pipe by a fan. The heat transported to the inside of the connecting pipe is rationally utilized. Furthermore, by setting up a fan, the heat is prevented from being slowly transported to the inside of the connecting pipe, thus avoiding heat loss during the heat transport process.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: an organic heat carrier boiler with a waste heat recovery structure, such as... Figure 3 and Figure 4As shown, the system includes a waste heat recovery structure 1, which comprises a recovery box 101 with a preheating chamber 102 at the bottom. A through-hole plate 103 is welded and fixed to the upper part of the recovery box 101, and a hollow U-shaped tube 104 is fixed to the bottom of the through-hole plate 103. Three sets of hollow U-shaped tubes 104 are arranged, with 13 tubes in each set arranged in a ring array. The arrangement of these components in three sets not only demonstrates the distribution of the ring array arrangement but also its practicality. The single-group hollow U-shaped tubes 104 are arranged in a ring array of 13 tubes, which are effectively and equidistantly distributed below the through-hole plate 103 to rapidly heat the injected liquid. At the same time, the hollow U-shaped tubes 104 are all made of copper metal material, which effectively and rapidly absorbs and transfers heat. A connecting plate 105 is welded and fixed inside the lower part of the recovery box 101, and a heat-insulating observation baffle 106 is installed at the bottom of the recovery box 101 by hinge rotation. At the same time, a thermometer 107 and a barometer 108 are respectively embedded on one side of the recovery box 101.

[0028] Furthermore, in the above scheme, a connecting cover 109 is welded and fixed above the through-hole plate 103, and cavity conveying pipes 1010 are embedded and installed on both sides of the connecting cover 109 through the recycling box 101. At the same time, one end of the cavity conveying pipe 1010 is embedded and extends into the preheating chamber 102. There is one set of cavity conveying pipes 1010, and the cavity conveying pipes 1010 are symmetrically arranged about the axis of the cavity heating block 1011. When there are two of the above components in one set, the symmetrical distribution and installation of the above components are reflected, as well as the diversion and conveying of the above components. When there are two of the above components in one set, the synchronous diversion and conveying and synchronous heat transfer utilization of the installation of the above components are effectively reflected.

[0029] Furthermore, in the above scheme, a cavity heating block 1011 is fixedly installed inside the preheating chamber 102, and the cavity heating block 1011 is embedded and connected to one end of the cavity conveying pipe 1010. An inlet valve pipe 1012 and an outlet valve pipe 1013 are respectively embedded and installed on one side of the recovery box 101.

[0030] like Figure 1 and Figure 2 As shown, an organic heat carrier boiler structure 2 is installed on one side of the waste heat recovery structure 1. The organic heat carrier boiler structure 2 includes an organic heat carrier boiler body 201 as the main body, and a fan 202 is installed in the organic heat carrier boiler body 201 through the air outlet pipe. At the same time, one end of the fan 202 is connected to one end of the connecting conveying pipe 203, and the other end of the connecting conveying pipe 203 passes through the top of the recovery box 101 and extends into the inside of the recovery box 101 and is welded and fixed to the connecting cover 109.

[0031] In the above scheme, when the heat carrier boiler body 201 is in use, the operator injects heated liquid into the preheating chamber 102 through the liquid inlet valve pipe 1012 and then closes the liquid inlet valve pipe 1012. At this time, when the heat is discharged, it is transported to the inside of the connecting conveying pipe 203 by the fan 202. The heat transported to the inside of the connecting conveying pipe 203 is transported to the inside of the connecting cover 109 and the cavity conveying pipe 1010 and then diverted again to the inside of the cavity U-shaped pipe 104 and the cavity heating block 1011 to preheat and heat the injected liquid and the placed items respectively.
