Description

Technical Field

[0001] This utility model relates to the technical field of steam generating devices, and specifically to a steam generator. Background Technology

[0002] Traditional steam generators often use a straight-through heating chamber, resulting in short water residence time and insufficient heating, leading to inadequate steam dryness. Existing improvement solutions, such as CN202022539231.3, extend the water flow path by setting up a labyrinth flow channel within the chamber, but these solutions suffer from problems such as complex channel structure, high manufacturing costs, and low steam generation efficiency. Utility Model Content

[0003] The present invention aims to provide a steam generator with a simple structure, high thermal efficiency and significantly improved steam dryness, thereby solving the problems of complex flow channels, low steam production efficiency and poor steam quality in the prior art.

[0004] Specifically, this utility model discloses a steam generator, comprising a shell, a heating element, a water inlet, and a steam outlet. The shell forms a sealed cavity, the heating element is disposed within the cavity, and the water inlet and steam outlet are disposed on the shell and connected to the cavity. The cavity is divided into a turbulence heating zone and a steam generation chamber along the direction from the water inlet to the steam outlet. The water inlet connects to the turbulence heating zone, and the steam outlet connects to the steam generation chamber. The turbulence heating zone is provided with multiple sets of staggered first and second turbulence plate groups, wherein: the first turbulence plate group includes first-type turbulence plates symmetrically disposed on both sides of the cavity, and the second turbulence plate group includes a second-type turbulence plate disposed in the center of the cavity. A baffle plate is vertically disposed in the middle of the turbulence heating zone, forming a double-arched flow diversion path with the turbulence plates; a flow-blocking plate is provided between the steam generation chamber and the turbulence heating zone, and a flow-through gap is provided on the flow-blocking plate to allow the high-temperature water entering the steam generation chamber to evaporate instantly by limiting the flow, thereby achieving flash evaporation.

[0005] The workflow is as follows: water flow → inlet → double-bow-shaped path in the turbulence heating zone for full heating → flow restriction by the baffle plate → flash evaporation in the steam generation chamber to generate dry steam → steam outlet.

[0006] Beneficial effects:

[0007] 1. Improved thermal efficiency: The double-bow-shaped flow channel greatly extends the water flow path, significantly improving the heating effect;

[0008] 2. Steam quality optimization: The baffle plate restricts the flow, causing the high-temperature water entering the steam generation chamber to evaporate instantly, which can greatly increase the steam dryness.

[0009] 3. Simplified structure: The spoiler can be processed separately using laser cutting one-piece molding process, which reduces the processing cost by 20%, and the flow channel has no dead corners, extending the cleaning cycle to twice that of the traditional structure.

Detailed Implementation

[0015] 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.

[0016] Reference Figures 1 to 4 The steam generator shown includes a shell, a heating element 2, a water inlet 3, and a steam outlet 4. The shell has an overall rectangular structure and is composed of a cover 101 and a shell body 102 connected by bolts, forming a sealed cavity inside.

[0017] The cavity is divided into a turbulence heating zone 1a and a steam generating chamber 1b along the direction from the water inlet 3 to the steam outlet 4. The water inlet 3 is located at the lower part of the shell and is connected to the external water supply system through a pipe; the steam outlet 4 is located at the upper part of the shell.

[0018] The heating element 2 is U-shaped and extends from one side of the housing along the edge to the other side.

[0019] Multiple sets of first turbulence plate group 5 and second turbulence plate group 6 are staggered along the water flow direction within the turbulence heating zone 1a;

[0020] The first spoiler group 5 includes a first type of spoiler symmetrically arranged on the left and right side walls of the cavity, with its free end maintaining a certain distance from the central axis of the cavity;

[0021] The second spoiler group 6 includes a second type of spoiler located in the center of the cavity, with the free end of the second type of spoiler maintaining a certain distance from the side wall of the cavity;

[0022] A vertical baffle 7 is installed in the middle of the turbulence heating zone 1a, which, together with the first turbulence plate group 5 and the second turbulence plate group 6, forms a double-bow-shaped flow diversion path.

[0023] The steam generating chamber 1b and the turbulence heating zone 1a are separated by a baffle plate. The baffle plate consists of a baffle plate body 801 set on the shell body 102 and a tongue plate 802 set on the cover 101. A slot is left in the middle of the baffle plate body 801. After the cover 101 and the shell body 102 are closed, the tongue plate 802 will be inserted into the slot of the baffle plate body 801. The height of the tongue plate 802 is less than that of the baffle plate body 801, so the tongue plate 802 will not be inserted to the bottom of the slot, thus naturally forming a flow gap 9.

[0024] Workflow:

[0025] Normal temperature water flows through inlet 3 into turbulence heating zone 1a, where it is continuously heated by U-shaped heating tubes in the double-arched flow channel; when high temperature water passes through the flow gap 9 of the baffle plate, the flow velocity increases sharply, and after entering the steam generation chamber 1b, flash evaporation occurs due to a sudden drop in pressure; the generated steam is discharged through steam outlet 4.

[0026] It should be noted that although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
