Description

Technical Field

[0001] This utility model relates to the field of gasifier technology, specifically a gasifier with a large circulation process. Background Technology

[0002] A vaporizer is a device used to heat liquid gas and turn it into gas. Simply put, cold liquid gas turns into gas after passing through a vaporizer. The heating can be indirect (steam-heated vaporizer, hot water bath vaporizer, natural ventilation air bath vaporizer, forced ventilation vaporizer, electric heating vaporizer, solid heat conduction vaporizer, or heat transfer fluid) or direct (hot gas or submerged combustion).

[0003] Finned tubes are the core component of most vaporizers. They absorb heat to heat the fluid inside the finned tubes, causing the fluid inside the finned tubes to change from a liquid state to a gaseous state.

[0004] The length of the finned tube directly affects the heat exchange effect of the medium. In the existing technology, most vaporizers have straight or U-shaped finned tubes. In order to improve the heat exchange effect, the vaporizer will be larger in size, which requires more space and is more expensive.

[0005] In view of this, there is an urgent need for a gasifier with a large circulation process. Summary of the Invention

[0006] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A gasifier with a large circulation process includes: a tank body, wherein a plurality of heat exchange pipes are provided in the tank body, and the plurality of heat exchange pipes are arranged in parallel.

[0009] The heat exchange pipeline includes several straight pipes and several connecting pipes. The straight pipes are arranged side by side and on the same plane. The connecting pipes are respectively arranged at the top and bottom of the straight pipes. The connecting pipes are used to connect two straight pipes. The straight pipes are connected sequentially from the outside to the inside.

[0010] One end of the heat exchange pipeline is the liquid inlet, and the other end is the gas outlet.

[0011] The parallel direction of the straight pipes is perpendicular to the parallel direction of the heat exchange pipes.

[0012] The liquid inlet is located at the bottom of the tank.

[0013] A diversion pipe is provided at the bottom of the tank, and the liquid inlets of several heat exchange pipelines are connected to the diversion pipe. A liquid delivery pipe is provided on the diversion pipe and extends to the bottom of the tank.

[0014] The air outlet is located at the bottom of the tank.

[0015] A manifold is provided at the bottom of the tank, and the outlets of several heat exchange pipelines are connected to the manifold. A gas delivery pipe is provided on the manifold and extends to the bottom of the tank.

[0016] In the same heat exchange pipeline, several connecting pipes located at the same end of the straight pipe are staggered in the horizontal direction.

[0017] The straight tube is provided with several fins in a circumferential direction.

[0018] The top of the tank is provided with several hanging lugs.

[0019] The bottom of the tank is provided with several support legs.

[0020] The above-described structure of this utility model can achieve the following beneficial effects:

[0021] During use, a high-temperature medium is filled into the tank, and then a low-temperature liquid is introduced through the inlet. The low-temperature liquid medium passes through the heat exchange pipes for heat exchange, and the gas after heat exchange is output from the outlet. Because several straight pipes are connected in a spiral pattern, the heat exchange path of the low-temperature medium is extended, and the bends connecting the low-temperature parts are made more flexible, making them less prone to cracking. This process can also maximize the heat exchange between the low-temperature medium and the external hot air to achieve better heat exchange effect. Furthermore, since the low-temperature medium flows sequentially into the straight pipes on both sides, the temperature of the low-temperature medium in the outermost straight pipe is the lowest. Therefore, the icing situation in the outermost straight pipe is similar, meaning that the weight on both sides of the tank is roughly the same, so the center of gravity of the tank does not change, which helps maintain the stability of the tank.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0029] refer to Figure 1-3 The vaporizer shown includes a large-circulation process vaporizer: a tank body 1, with several heat exchange pipes arranged in parallel within the tank body 1; each heat exchange pipe includes several straight pipes 2 and several connecting pipes 3. The straight pipes 2 are arranged in parallel and on the same plane, and the connecting pipes 3 are respectively located at the top and bottom of the straight pipes 2, connecting pipes 3 connecting two straight pipes 2. The straight pipes 2 are connected sequentially from the outside to the inside (that is, the heat exchange pipes are generally in a planar spiral shape; if there are 6 straight pipes 2, from one side they are arranged as the first pipe, second pipe, third pipe, fourth pipe, fifth pipe, and sixth pipe, the connection sequence is: the top of the first pipe 1 connects to the top of the sixth pipe, the bottom of the sixth pipe connects to the bottom of the second pipe, the top of the second pipe connects to the top of the fifth pipe, the bottom of the fifth pipe connects to the bottom of the third pipe, and so on). The top of the tube is connected to the top of the fourth tube. One end of the heat exchange pipe is the liquid inlet (located at the bottom of the first tube), and the other end is the gas outlet (located at the bottom of the fourth tube). In this way, when in use, high-temperature medium is filled into the tank 1, and then low-temperature liquid is introduced from the liquid inlet. The low-temperature liquid medium passes through the heat exchange pipe for heat exchange, and the gas after heat exchange is output from the gas outlet. Since several straight tubes 2 are connected in a spiral shape, the heat exchange path of the low-temperature medium is extended, the heat exchange time of the low-temperature medium is increased, and the heat exchange effect is improved. Furthermore, since the low-temperature medium flows into the straight tubes 2 on both sides in sequence, the temperature of the low-temperature medium in the outermost straight tube 2 is the lowest. Therefore, the icing situation at the outermost straight tube 2 is similar, that is, the weight on both sides of the tank 1 is roughly the same, so that the center of gravity of the tank 1 will not change, which is conducive to maintaining the stability of the tank 1.

[0030] like Figure 2 and Figure 3 As shown, the parallel direction of several straight pipes 2 is perpendicular to the parallel direction of several heat exchange pipes, that is, the straight pipes 2 of several heat exchange pipes are distributed in a rectangular array, which improves the uniformity of heat exchange.

[0031] like Figure 1 and Figure 2 As shown, to facilitate the input of cryogenic liquid and the output of cryogenic gas, the liquid inlet is located at the bottom of the tank body 1, and the gas outlet is located at the bottom of the tank body 1. A distribution pipe 4 is installed at the bottom of the tank body 1, and the liquid inlets of several heat exchange pipes are connected to the distribution pipe 4. A liquid delivery pipe 5 is installed on the distribution pipe 4, extending to the bottom of the tank body 1. A manifold 6 is installed at the bottom of the tank body 1, and the gas outlets of several heat exchange pipes are connected to the manifold 6. A gas delivery pipe 7 is installed on the manifold 6, extending to the bottom of the tank body 1. Cryogenic liquid is input into the distribution pipe 4 through the liquid delivery pipe 5, and after being distributed through the distribution pipe 4, it enters several heat exchange pipes for heating. The gas after heat exchange flows into the manifold 6, and after being combined through the manifold 6, it is output from the gas delivery pipe 7. Since both the gas delivery pipe 7 and the liquid delivery pipe 5 are located at the bottom of the tank body 1, they are easy to connect and operate.

[0032] like Figure 2 As shown, in order to save space and reduce the overall size of the equipment, several connecting pipes 3 located at the same end of the straight pipe 2 in the same heat exchange pipeline are staggered in the horizontal direction to reduce the height of the equipment.

[0033] To further optimize the heat exchange effect, the straight tube 2 is provided with several fins in the circumferential direction.

[0034] like Figure 1 As shown, in order to facilitate the hoisting of tank 1, several hanging lugs 8 are provided on the top of tank 1 for hook suspension.

[0035] like Figure 1 As shown, the bottom of the tank 1 is provided with several legs 9, which support the tank 1 and keep it suspended in the air.

[0036] In summary, during use, a high-temperature medium is filled into the tank 1, and then a low-temperature liquid is introduced through the inlet. The low-temperature liquid medium passes through the heat exchange pipeline for heat exchange, and the gas after heat exchange is output from the outlet. Since several straight pipes 2 are connected in a spiral pattern, the heat exchange path of the low-temperature medium is extended, the heat exchange time of the low-temperature medium is increased, and the heat exchange effect is improved. Furthermore, since the low-temperature medium flows sequentially into the straight pipes 2 on both sides, the temperature of the low-temperature medium in the outermost straight pipe 2 is the lowest. Therefore, the icing situation at the outermost straight pipe 2 is similar, which means that the weight on both sides of the tank 1 is roughly the same, so that the center of gravity of the tank 1 does not change, which is conducive to maintaining the stability of the tank 1.

[0037] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
