Description

Technical Field

[0001] This utility model belongs to the field of steam heating technology, specifically an energy-saving steam heating device. Background Technology

[0002] Shrink-setting machines are industrial fabric pre-shrinking and setting equipment, mainly used in the textile industry. Pre-shrinking reduces fabric shrinkage during sewing and ironing, preventing deformation of finished garments and improving cutting efficiency and the bonding between lining and outer fabric. The steam in a shrink-setting machine is typically provided by a steam generator. The steam, passing through a high-temperature environment, maintains the fabric at a specific size under tension. After cooling, the fiber macromolecular structure is fixed, achieving dimensional stability. Steam pre-shrinking reduces the risk of shrinkage in subsequent processing (such as cutting, sewing, and ironing), and is especially suitable for easily shrinking materials such as cotton lace, reducing the actual shrinkage rate through pre-treatment. However, to meet the higher-temperature processing requirements of some fabrics, a more powerful steam generator with a larger evaporation capacity is needed, thus consuming a significant amount of electricity. Utility Model Content

[0003] To address the problems mentioned above, this utility model provides an energy-saving steam heating device. By innovating the steam heating structure and optimizing thermal efficiency, and combining it with a steam generator with a rated evaporation capacity of 80 kg / h, its effective thermal performance can completely replace a steam generator with a rated evaporation capacity of 150 kg / h. Under the same process conditions, it achieves the same or even better processing results, with a comprehensive energy saving rate of ≥40%. This not only saves steam but also saves the electrical energy required to produce steam.

[0004] This utility model provides an energy-saving steam heating device, which includes multiple steam pipes connected in sequence and internally interconnected. A steam inlet is provided on one end of the steam pipe, and a steam outlet is connected to the steam pipe at the end away from the steam inlet. Each steam pipe is equipped with a heating element.

[0005] Furthermore, four steam pipes are installed.

[0006] Furthermore, a cylinder is fitted around the steam pipe, and the steam inlet is connected to the inside of the cylinder. A steam inlet pipe is connected to the cylinder, with one end of the steam inlet pipe penetrating into the cylinder and connecting to the inside of the cylinder, and the other end of the steam inlet pipe connected to the steam production equipment.

[0007] Furthermore, the cylinder body is wrapped with an insulation layer.

[0008] Furthermore, the insulation layer is covered with an outer shell, on which two fixing plates are fixedly connected, and the fixing plates have waist-shaped holes.

[0009] Furthermore, a baffle plate is fixedly connected to the inner wall of the cylinder. The baffle plate is located below the steam pipe, and a channel for steam to pass through is left between one end of the baffle plate and the inner wall of the cylinder.

[0010] Furthermore, a drain pipe is connected to the lower part of the cylinder block, and a drain valve is installed on the drain pipe.

[0011] Furthermore, it also includes an intelligent temperature control system, with the heating element electrically connected to the intelligent temperature control system.

[0012] Furthermore, a multi-way valve is installed at the end of the steam outlet pipe that is away from the steam pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) By innovating the steam heating structure and optimizing the thermal efficiency, this application is equipped with a steam generator with a rated evaporation capacity of 80 kg / h. Its effective thermal performance can completely replace the steam generator with a rated evaporation capacity of 150 kg / h. Under the same process conditions, it can achieve the same or even better processing effect. The comprehensive energy saving rate is ≥40%, which not only saves steam, but also saves the electrical energy required to produce steam.

[0015] (2) The steam generated by the steam production equipment first enters the cylinder through the steam inlet pipe for storage, and then enters the steam pipe through the steam inlet for secondary heating. The cylinder with pre-stored steam has a certain steam buffering capacity. During the steam production process of the steam production equipment, there may be fluctuations in the steam supply. The pre-stored steam in the cylinder can effectively cope with the fluctuations in the steam supply, ensure the rapid response and high stability of the steam, and further guarantee the continuous and reliable supply of high-quality steam.

[0016] (3) When steam enters the cylinder through the steam inlet pipe, it will be mixed with a certain amount of water. The water remains at the bottom of the cylinder under the action of gravity. The baffle plate has the function of separating water and steam, so that the water is blocked below the baffle plate. The steam flows upward through the channel between the baffle plate and the cylinder and enters the steam pipe through the steam inlet. Attached Figure Description

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The following is in conjunction with the appendix Figure 1 To be continued Figure 4 The present invention will be described in detail with specific embodiments.

[0025] Reference Figures 1-4 This utility model provides an energy-saving steam heating device, comprising multiple parallel steam pipes 1, which are connected sequentially and internally. One end of each steam pipe 1 has a steam inlet, and the end away from the steam inlet has a steam outlet pipe 2. Each steam pipe 1 contains a heating element 3. Steam generated by a steam generator enters the steam pipe 1 through the steam inlet. The heating element 3 in the steam pipe 1 reheats the steam, generating near-saturated or slightly superheated dry steam (extremely low moisture content). The steam quality is excellent, meeting stringent process requirements, and the maximum temperature can reach 250℃, satisfying high-temperature processing needs. Subsequently, the reheated steam is supplied to equipment requiring high-temperature, high-quality steam through the steam outlet pipe 2. By innovating the steam heating structure and optimizing thermal efficiency, this application, when paired with a steam generator with a rated evaporation capacity of 80 kg / h, can completely replace a steam generator with a rated evaporation capacity of 150 kg / h in terms of effective thermal performance. Under the same process conditions, it achieves the same or even better processing results, with a comprehensive energy saving rate of ≥40%. This not only saves steam but also saves the electrical energy required to produce steam.

[0026] Four steam pipes 1 are provided. Through testing and practical application, it has been found that setting four steam pipes 1 and correspondingly equipping them with four heating tubes 3 achieves the best energy-saving effect while meeting processing requirements. The longitudinal section of the four steam pipes 1 in this application is trapezoidal, which makes the structure more compact. Of course, the four steam pipes 1 can also be arranged sequentially in the same plane. This application does not make specific limitations on the spatial structure of the four steam pipes 1.

[0027] A cylinder 4 is fitted around the outside of the steam pipe 1. The steam inlet is connected to the inside of the cylinder 4. A steam inlet pipe 5 is connected to the cylinder 4. One end of the steam inlet pipe 5 passes through the cylinder 4 and is connected to the inside of the cylinder 4. The other end of the steam inlet pipe 5 is connected to the steam production equipment. The steam production equipment mentioned here is not limited to a steam generator, but can also be a steam boiler or other equipment capable of producing steam. This application does not limit the specific structure of the steam production equipment, as long as it can produce steam. The steam generated by the steam production equipment first enters the cylinder 4 through the steam inlet pipe 5 for storage, and then enters the steam pipe 1 through the steam inlet for secondary heating. The effective volume of the cylinder 4 is 25L (meeting the design requirement of ≤30L). The pre-stored steam in the cylinder 4 has a certain steam buffering capacity. During the steam production process of the steam production equipment, there may be fluctuations in the steam supply. The pre-stored steam in the cylinder 4 can effectively cope with the fluctuations in the steam supply, ensuring rapid response and high stability of the steam, and further guaranteeing a continuous and reliable supply of high-quality steam.

[0028] The cylinder body 4 is covered with an insulation layer 6. The insulation layer 6 can keep the cylinder body 4 warm, thereby reducing the heat loss of steam inside the cylinder body 4.

[0029] An outer shell 7 is fitted over the insulation layer 6. Two fixing plates 8 are fixedly connected to the outer shell 7, and the fixing plates 8 have oblong holes 9. The outer shell 7 provides protection for the cylinder 4 and the steam pipe 1 inside the cylinder 4, and also serves as the mounting carrier for the cylinder 4. The outer shell 7 can be installed on other equipment via the two fixing plates 8, enabling quick installation and disassembly. The oblong holes 9 on the fixing plates 8 provide a certain degree of redundancy for the installation of the outer shell 7, allowing for normal installation even if the installation hole positions are slightly off.

[0030] A baffle plate 10 is fixedly connected to the inner wall of the cylinder 4. The baffle plate 10 is located below the steam pipe 1, and a channel for steam to pass through is left between one end of the baffle plate 10 and the inner wall of the cylinder 4. When steam enters the cylinder 4 through the steam inlet pipe 5, it will be mixed with a certain amount of water. The water remains at the bottom of the cylinder 4 under the action of gravity. The baffle plate 10 has the function of separating water and steam, blocking the water below the baffle plate 10, while the steam flows upward through the channel between the baffle plate 10 and the cylinder 4, and enters the steam pipe 1 through the steam inlet.

[0031] A drain pipe 11 is connected to the lower part of the cylinder body 4, and a steam trap is installed on the drain pipe 11. The steam trap is existing technology and is not shown in the figure. The structure of the steam trap will not be described in detail here. The steam trap can open automatically under certain conditions. Therefore, when too much water remains in the cylinder body 4, the steam trap can open automatically, allowing the water in the cylinder body 4 to be discharged from the cylinder body 4 through the drain pipe 11.

[0032] The energy-saving steam heating device of this application also includes an intelligent temperature control system, and the heating element 3 is electrically connected to the intelligent temperature control system. The intelligent temperature control system is also prior art and will not be described in detail here. This application integrates an intelligent temperature control system, which enables precise and continuous adjustment of the steam temperature and supports multiple preset levels to adapt to different process requirements. Furthermore, it enables adaptive adjustment of the steam temperature, saving labor costs.

[0033] A multi-way valve (not shown in the figure) is installed at the end of the steam outlet pipe 2 away from the steam pipe 1. The multi-way valve here refers to a three-way valve, a four-way valve or other valves with multiple passages. The setting of the multi-way valve can realize the supply of high-quality steam from multiple sources, and can also reasonably allocate the amount of steam according to the equipment requirements.

[0034] This application can be applied not only to shrinking and setting machines but also to other equipment requiring steam heating. Its application scope is not limited to shrinking and setting machines. Furthermore, this application allows for flexible configuration by replacing heating elements 3 with different power ratings according to actual production capacity and processing requirements, achieving optimal energy efficiency and significantly improving the economic benefits of enterprises. This application is an integrated heating unit that combines heating, buffering, and distribution functions. Its more compact structure significantly shortens the steam transport path, reduces pipeline heat loss, improves the overall system thermal efficiency, ensures a continuous and stable steam supply, and offers significant energy-saving benefits, further enhancing the economic benefits of enterprises.

[0035] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
