Steam line of a steam humidification mechanism

Abstract

This utility model discloses a steam pipeline for a steam humidification mechanism. A drying mechanism is installed on the left and right frames. The drying mechanism includes a steam inlet, an inner steam channel, and a drain outlet connected in sequence. The steam inlet and drain outlet are connected to a steam distributor for water circulation. The inner steam channel includes two sub-channels, forming a symmetrical S-shaped path on both sides for the horizontal, meandering transport of steam to heat the inner surface. By dividing the inner steam channel into left and right sub-channels, this utility model increases the circulation speed of the two steam paths, thus avoiding the problem of reduced heating and drying capacity due to temperature drops in the later sections of a longer channel. Halving the length of the channel in the width direction also reduces the temperature difference between the left and right sides, which helps maintain consistent evaporation performance throughout the width direction. Dividing the channel into two reduces the initial setup cost and the subsequent cleaning and maintenance costs and difficulties.

Description

Technical Field

[0001] This utility model relates to the field of humidification device technology, and more specifically to a steam pipeline of a steam humidification mechanism. Background Technology

[0002] In processing equipment such as coating equipment, papermaking equipment, leather composite equipment, and textile equipment, the materials being processed need to be humidified to facilitate further processing. In the prior art, the applicant's previous application, application number 202411105317.1, entitled "A Steam Humidification Mechanism with Precisely Controllable Humidification Amount," describes a currently used steam humidification mechanism. This mechanism humidifies the material by conveying it through left and right frames, with the humidification mechanism spraying steam to humidify the material. Residual liquid on the inner surface of the left and right frames is evaporated by a drying mechanism to keep the mechanism dry and prevent contamination of the processing environment by residual liquid. However, the drying mechanism uses a horizontal S-shaped passage from top to bottom for steam or water transport. This long passage increases the difficulty of equipment layout and maintenance. Furthermore, as steam or water flows through the long passage, heat loss leads to a significant temperature difference between the beginning and end of the passage, with the lower end being colder. In processing scenarios where a large amount of humidifying steam is sprayed, the rapidly flowing residual liquid may not be evaporated in time. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a steam pipeline for a steam humidification mechanism. By redesigning the steam channel, the channel length is reduced, thereby simplifying the layout and maintenance, while also mitigating the impact of temperature differences on evaporation performance.

[0004] This utility model provides the following technical solution: a steam pipeline of a steam humidification mechanism, including a left frame and a right frame, with a drying mechanism installed on the left and right frames. The drying mechanism includes a steam inlet, an inner steam channel and a drain outlet connected in sequence. The steam inlet and drain outlet are connected to a steam distributor for water circulation. The inner steam channel includes two sub-channels on the left and right sides, which form a symmetrical S-shaped passage on both sides for the detour and horizontal transport of steam to heat the inner surface.

[0005] As an improvement, the inlets and outlets of the two sub-channels are arranged adjacent to each other, and the pipes for the steam inlet and drain outlet extend to the middle of the left and right frames to connect with the inlets and outlets of the two sub-channels respectively.

[0006] As an improvement, the left and right frames are divided into upper and lower regions, with two sub-channels symmetrically arranged in the upper and lower regions, and the corresponding upper and lower sub-channels are connected by a vertical pipe.

[0007] As an improvement, the vertical tube is located in the middle of the left and right frames.

[0008] As an improvement, the left and right frames are divided into upper and lower regions, with independent steam inlets, internal steam channels, and drain outlets for steam transport in the upper and lower regions respectively.

[0009] As an improvement, the steam inlets and drain outlets of the upper and lower zones are located on the same side of the left and right frames.

[0010] The beneficial effects of this invention are as follows: Dividing the inner steam channel into two sub-channels (left and right) increases the circulation speed of the two steam paths, thus avoiding the problem of reduced heating and drying capacity due to temperature drop in the later section of the originally longer channel; halving the length of the channel in the width direction also reduces the temperature difference between the left and right sides, which helps maintain the consistency of evaporation performance throughout the width direction. Dividing the channel into two reduces the initial layout cost, as well as the cost and difficulty of subsequent separate cleaning and maintenance. Attached Figure Description

[0014] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0015] like Figure 1 , 2 Figure 3 shows a specific embodiment of the steam pipeline of the steam humidification mechanism of this utility model. This embodiment includes a left frame 1 and a right frame 2. A drying mechanism 3 is provided on the left frame 1 and the right frame 2. The drying mechanism 3 includes a steam inlet 31, an inner steam channel 32 and a drain outlet 33 connected in sequence. The steam inlet 31 and the drain outlet 33 are connected to a steam distributor for water circulation. The inner steam channel 32 includes two sub-channels 321 on the left and right sides. The two sub-channels 321 form a symmetrical S-shaped passage on both sides for the detour horizontal transport of steam to heat the inner surface.

[0016] In use, the steam humidification mechanism of this utility model can be directly referred to in the applicant's previous application, application number 202411105317.1, entitled "A Steam Humidification Mechanism with Precise and Controllable Humidification Amount". The vertically arranged left frame 1 and right frame 2 are separated by an opening and closing drive 6. The material to be humidified is then passed between them from top to bottom. Afterward, the left frame 1 and right frame 2 are closed to a suitable distance, forming a suitable gap where the material does not touch. The material is conveyed by a conveying mechanism from the preceding or following process, and humidification is performed between the left frame 1 and right frame 2 by the humidification mechanism 4. Specifically, depending on the material being processed, single-sided humidification or simultaneous double-sided humidification can be used. The humidification mechanism 4 of one frame or both frames can be activated as needed. During heating and drying, preheated steam from the steam distributor is piped to the steam inlet 31. The steam is then transported along the inner steam channel 32 formed by the inner surfaces of the left frame 1 and right frame 2. The inner steam channel 32 is divided into two sub-channels 321, forming a meandering flow path. This allows the high-temperature steam to cover the entire inner surface, effectively heating it and evaporating moisture to achieve the drying effect. The steam and condensed moisture from the inner steam channel 32 flow along the channel to the drain outlet 33, where they are recovered and returned to the steam distributor. This utilizes the waste heat and allows the steam to be reheated and reintroduced into the drying cycle. The symmetrical arrangement of the two sub-channels 321 ensures symmetrical steam flow, maintaining consistent heating on both sides and facilitating the heating and drying of moisture on the inner surfaces of the left frame 1 and right frame 2. Dividing the steam into two sub-channels 321 controls component manufacturing costs and reduces local maintenance and replacement costs. As a supplement to the prior art, the left frame 1 and the right frame 2 also include an outer frame steam channel 5, which heats the surrounding frame of the left frame 1 and the right frame 2 after steam is introduced.

[0017] As an improved specific implementation, the inlets and outlets of the two sub-channels 321 are arranged adjacent to each other, and the pipes of the steam inlet 31 and the drain outlet 33 extend to the middle of the left frame 1 and the right frame 2 respectively to connect with the inlets and outlets of the two sub-channels 321.

[0018] like Figure 1 , 2As shown, the steam inlet 31 extends to the middle of the left frame 1 and the right frame 2, connecting to the sub-channels 321 on both sides. This ensures that the steam temperature entering the two sub-channels 321 is consistent at the beginning, maintaining a consistent heating state for the entire plate surface throughout the steam flow cycle, avoiding temperature differences, and thus ensuring the heating and drying effect on the liquid inside the plate. Furthermore, extending the steam inlet 31 and the drain outlet 33 to the middle of the left frame 1 and the right frame 2 is a relatively optimized arrangement, avoiding excessive increases in piping costs and achieving an effective balance between performance and cost.

[0019] As an improved specific implementation, the left frame 1 and the right frame 2 are divided into an upper region 01 and a lower region 02. Two sub-channels 321 are symmetrically arranged in the upper region 01 and the lower region 02, and the corresponding upper and lower sub-channels 321 are connected by a vertical pipe 322.

[0020] like Figure 1 , 2 As shown, the left frame 1 and right frame 2 are large-area frame structures, divided into upper region 01 and lower region 02. Sub-channels 321 are symmetrically arranged in upper region 01 and lower region 02 respectively. Each sub-channel 321 carries steam and water, transferring heat to its respective region. The separately arranged channels can be cleaned and maintained independently. The corresponding upper and lower sub-channels 321 are connected by a vertical pipe 322, enabling separate flow of steam and water.

[0021] As an improved specific implementation, the vertical tube 322 is located in the middle of the left frame 1 and the right frame 2.

[0022] like Figure 1 As shown, the two vertical pipes 322 are set in the middle of the left frame 1 and the right frame 2 for easy centralized arrangement and management.

[0023] As an improved specific implementation, the left frame 1 and the right frame 2 are divided into an upper region 01 and a lower region 02. The upper region 01 and the lower region 02 are respectively provided with independent steam inlets 31, inner steam channels 32 and drain outlets 33 for steam transportation.

[0024] like Figure 2As shown, in another implementation, a set of drying mechanisms 3 is provided for the upper region 01 and the lower region 02 respectively. That is, the upper region 01 and the lower region 02 are provided with independent steam inlets 31, inner steam channels 32 and drain outlets 33 respectively. In this implementation, the upper and lower flow channels are split, which can further shorten the length of each sub-channel 321, thereby minimizing the impact of temperature reduction. The two sub-channels 321 of the lower region 02 can also provide higher temperatures for heating the inner plate, which can better ensure the heating and drying effect of the entire left frame 1 and right frame 2.

[0025] As an improved specific implementation, the steam inlet 31 and drain outlet 33 of the upper region 01 and the lower region 02 are both located on the same side of the left frame 1 and the right frame 2.

[0026] like Figure 2 As shown, the two sets of steam inlets and drain outlets are located on the same side, which facilitates the connection and management of pipelines on the same side, reduces the difficulty of equipment management and maintenance, and makes the work site neat and orderly, allowing operators to operate the equipment more conveniently.

All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
