Description

A flexible connecting element for a vaporizer finned tube and a vaporizer Technical Field

[0001] This utility model relates to the field of gasifier technology, specifically to a flexible connecting element for a gasifier finned tube and a gasifier. 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. The finned tubes in the vaporizer are fixed by connecting elements. One connecting element can fix multiple finned tubes in a circumferential direction. Due to the thermal expansion and contraction of the finned tubes, the connecting elements need to have the function of deformation to compensate for the deformation of the finned tubes. The connecting elements in the existing technology are generally rectangular or circular tubes, which have poor deformation capacity, resulting in a mediocre compensation effect.

[0004] In view of this, there is an urgent need for a flexible connecting element for a vaporizer finned tube and a vaporizer. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flexible connecting element for a vaporizer finned tube includes: a tube body, wherein the tube body is provided with a plurality of deformation grooves in a circumferential direction, and the deformation grooves extend along the axial direction of the tube body;

[0008] Each of the deformation grooves is provided with a connecting plate, which extends along the axial direction of the tube body. A finned tube connection structure is provided on the side of the connecting plate away from the tube body.

[0009] The tube is composed of several first plates and several second plates. The first plates and several plates are connected in sequence to form an annular tube, and the first plates and second plates are arranged at intervals.

[0010] The second plate is recessed into the inner side of the tube to form a deformation groove.

[0011] The second plate is arc-shaped.

[0012] The second material is arc-shaped.

[0013] The first plate is arc-shaped, bulging outwards from the tube body.

[0014] The first plate is arc-shaped.

[0015] The connecting plate is arc-shaped.

[0016] The connecting plate is composed of at least two arc-shaped plates, with the openings of the two arc-shaped plates facing opposite directions.

[0017] The finned tube connection structure includes a C-shaped plate.

[0018] A vaporizer includes a flexible connecting element for the vaporizer finned tube.

[0019] The above-described structure of this utility model can achieve the following beneficial effects:

[0020] During installation, the fins of the finned tube are connected to the finned tube connection structure. When the aerator is working, the finned tube undergoes thermal expansion and contraction. Since the connecting plate is located at the deformation groove, when the finned tube acts on the connecting plate, the deformation groove deforms, thereby compensating for the thermal expansion and contraction of the finned tube and maintaining the stability of the aerator's operation. The setting of the deformation groove increases the deformation range and improves the compensation capability of the connecting element. This solves the common industry phenomenon of cracking at the connection between the connecting element and the finned tube due to insufficient compensation, and completely solves the connection strength and overall safety of the equipment.

[0023] 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.

[0024] 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.

[0025] The present application will be further described in detail below with reference to Figure 1.

[0026] Example 1, referring to Figure 1, describes a flexible connecting element for a vaporizer finned tube, comprising: a tube body with several circumferentially arranged deformation grooves 1 extending axially along the tube body; a connecting plate 2 (extending from the inside of the deformation groove 1 towards its opening) is provided at each deformation groove 1, extending axially along the tube body; a finned tube connecting structure is provided on the side of the connecting plate 2 away from the tube body. During installation, the fins of the finned tube are connected to the finned tube connecting structure. When the vaporizer operates, the finned tube undergoes thermal expansion and contraction. Because the connecting plate 2 is located at the deformation groove 1, when the finned tube acts on the connecting plate 2, the deformation groove 1 deforms, thus compensating for the thermal expansion and contraction of the finned tube, thereby maintaining the stability of the vaporizer operation. The deformation groove 1 increases the deformation range and improves the compensation capability of the connecting element.

[0027] As shown in Figure 1, the tube body can be specifically composed of several first plates 3 and several second plates 4. The several first plates 3 and several plates 4 are connected in sequence to form an annular tube body, with the first plates 3 and second plates 4 spaced apart. The second plates 4 are recessed into the inner side of the tube body to form a deformation groove 1. In actual processing, the tube body is integrally formed. In order to improve the deformation capacity, the second plates 4 are arc-shaped, preferably circular arc-shaped, to improve the deformation capacity. In order to cooperate with the deformation of the second plates 4, the first plates 3 are arc-shaped protruding outward of the tube body, preferably circular arc-shaped. When the second plates 4 deform, they apply a force to the first plates 3 on both sides. At this time, the first plates 3 deform to cooperate in compensation and improve the compensation capacity.

[0028] As shown in Figure 1, in order to further improve the compensation capability, the connecting plate 2 is arc-shaped and is composed of at least two arc-shaped plates with the openings of the two arc-shaped plates facing opposite directions. When the force of the finned tube fins acts on the connecting plate 2 at the first moment, the connecting plate 2 deforms and compensates, which further improves the compensation capability of this application.

[0029] As shown in Figure 1, in order to facilitate the installation of finned tube fins, the finned tube connection structure includes a C-shaped plate 5. During installation, the fins are inserted into the opening of the C-shaped plate 5 for installation, which is convenient and stable.

[0030] In a further optimization, this embodiment has four deformation grooves 1, and the four deformation grooves 1 are evenly arranged in a circle.

[0031] In particular, this utility model also provides a vaporizer that uses the above-mentioned flexible connecting element for vaporizer finned tubes.

[0032] In summary, during installation, the fins of the finned tube are connected to the finned tube connection structure. When the aerator is working, the finned tube undergoes thermal expansion and contraction. Since the connecting plate 2 is located at the deformation groove 1, when the finned tube acts on the connecting plate 2, the deformation groove 1 deforms, thereby compensating for the thermal expansion and contraction of the finned tube and maintaining the stability of the aerator's operation. The setting of the deformation groove 1 increases the deformation range and improves the compensation capability of the connecting element.

[0033] 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.
