Description

Technical Field

[0001] The utility model relates to the technical field of steam box devices, in particular to a steam box which realizes energy filtering and recovery through heat exchange. Background Art

[0002] The textile industry requires post-dyeing and finishing to dye and shape products and determine their appearance and properties. Ventilation holes are installed in the steamer to facilitate the heating cycle. This ventilation also causes heat loss, requiring a long warm-up period before each production run. Steam (hereinafter referred to as "new steam") is introduced into the steamer through pipes. After steaming (hereinafter referred to as "old steam"), it is discharged and removed through the outlet. Much of the volatilized steam is inhaled by the operator's mouth and nose, and the subsequent washing process requires new tap water to support production. However, existing steamer heating times are long, energy consumption is high, and it is prone to environmental pollution and health hazards.

[0003] Comparative document CN105444592A discloses a concrete pipe pile autoclave residual gas recovery system, specifically comprising an autoclave, a boiler room soft water tank, and a soft water collection tank. It also includes a shell-and-tube heat exchanger, the tube-side inlet of the shell-and-tube heat exchanger being connected to the outlet pipe of the boiler room soft water tank, the tube-side outlet being connected to the soft water collection tank, the shell-side inlet of the shell-and-tube heat exchanger being connected to the residual steam discharge pipe of the autoclave, and a drain valve being provided at the shell-and-tube heat exchanger's shell-side outlet. The shell-and-tube heat exchanger utilizes heat exchange between the soft water in the boiler room soft water tank and the residual steam, raising the temperature of the cold soft water and reducing the boiler's energy consumption, thereby achieving the purpose of waste heat utilization. However, this structure fails to fully utilize the steam, resulting in significant heat waste. Utility Model Content

[0011] Beneficial effects:

[0012] By connecting a shell-and-tube heat exchanger to a steamer, this utility model allows the used steam in the steamer to be directly collected and discharged into the shell-and-tube heat exchanger. The heat of this used steam is then exchanged with cold water introduced at the tube-side inlet, heating the cold water entering the steamer to a desired temperature before being discharged into the steamer. This maximizes the use of the used steam in the steamer and reduces heat waste. Furthermore, a filter device is connected to the shell-side outlet to filter the wastewater condensed after heat exchange in the heat exchanger for reuse, reducing water waste, preventing wastewater from contaminating water sources, and significantly reducing the content of harmful substances in the air.

[0016] Combine Figures 1 to 2As shown, this embodiment provides a steamer that realizes energy filtration and recovery based on heat exchange, including a steamer housing 1, a shell and tube heat exchanger 2, and a filtering device 3. The shell and tube heat exchanger 2 includes a tube-side inlet 21, a tube-side outlet 22, a shell-side inlet 23, and a shell-side outlet 24. The tube-side inlet 21 is suitable for introducing an external water source. The tube-side outlet 22 is connected to the shell-side inlet 23 of the steamer housing 1. The shell-side inlet 23 is suitable for introducing used steam in the steamer housing 1 to heat cold water introduced from the tube-side inlet 21 by the used steam. The tube-side outlet 22 is connected to the tube-side inlet 21 to introduce water heated by the used steam into the steamer housing 1. The shell-side outlet 24 is connected to the filtering device 3 to cool and filter the water liquefied by the shell and tube heat exchanger 2 for use in water washing.

[0017] In this embodiment, the steamer is an existing product that heats incoming water, converting it into steam for product processing. The steamer housing 1 is provided with an inlet and an outlet, respectively for introducing cold water and discharging used steam. "Used steam" here refers to steam that needs to be discharged after processes such as heating the product.

[0018] The shell-and-tube heat exchanger 2 is a conventional shell-and-tube heat exchange device. It includes an internal water pipe and a heat exchange chamber, with the internal water pipe positioned within the heat exchange chamber. The internal water pipe includes a tube-side inlet 21 and a tube-side outlet 22, and the heat exchanger includes a shell-side inlet 23 and a shell-side outlet 24. In this embodiment, the tube-side inlet 21 is connected to an external tap water source, the shell-side inlet 23 is connected to the outlet of the steamer housing 1, allowing the old steam within the steamer housing 1 to be discharged into the heat exchanger, and the tube-side outlet 22 is connected to the water inlet of the steamer housing 1. When cold water flows from the tube-side inlet 21 through the internal water pipe, the old steam introduced into the heat exchange chamber exchanges heat with the cold water within the internal water pipe, heating the cold water to a certain temperature. As a result, the water discharged into the steamer housing 1 is at a higher temperature, allowing for rapid vaporization within the steamer housing 1, thereby improving the steamer's operating efficiency. The water after heat exchange with the old steam is liquefied and discharged through the shell side outlet 24 to the filter device 3 for filtration.

[0019] The filter device 3 is provided with a pure water outlet 31 and a waste water outlet 32. The pure water outlet 31 is connected to the water washing tank to recycle the water, and the waste water outlet 32 is suitable for discharging waste water and impurities, thereby improving water utilization. The filter device 3 of this embodiment can adopt commonly used liquid filters on the market, which are not listed here one by one.

[0020] In a preferred embodiment, the shell-side inlet 23 is equipped with a valve for controlling the opening and closing of the shell-and-tube heat exchanger 2 and the steamer housing 1. This valve allows the steamer to be disconnected from the shell-and-tube heat exchanger 2, allowing the steamer to be used independently. Furthermore, an openable inspection port is provided on the steamer housing 1 for easy cleaning and inspection.

[0021] In this solution, a heat exchange device is installed on the steam box, which can make the temperature and pressure inside the box more stable. At the same time, it can collect the "old waste steam" discharged during the steaming process of the steam box, liquefy it into water through the heat exchanger, cool it down and filter it, and then use it for water washing, thereby reducing water consumption.

[0022] It should be understood that the above are only preferred implementations of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.

[0023] The above description of the drawings used in the implementation manner only shows certain embodiments of the present invention and should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without paying any creative work.
