[0002] In modern food processing, catering cooking and many industrial production fields, the steamer is widely used. In the running process of the steamer, the material is heated by steam to realize the process purposes such as food cooking, product steaming, disinfection and sterilization. However, the traditional steamer has a significant problem in work, that is, a large amount of pressure relief steam is generated.

[0003] These pressure relief steam is usually directly discharged into the environment, which not only causes great waste of energy, but also may have adverse effects such as heat pollution and excessive humidity on the surrounding environment. At present, energy is becoming increasingly scarce and environmental protection requirements are continuously improving. How to effectively recycle the pressure relief steam generated by the steamer has become a technical problem to be solved.

[0004] At present, although there are some steam recovery devices, most of them have defects such as complex structure, low recovery efficiency, poor compatibility with the steamer, etc. For example, some devices are difficult to stably operate in the high-temperature and high-pressure steam environment of the steamer, resulting in high equipment failure rate; some recovery devices cannot realize efficient heat exchange of steam, so that the recovered heat cannot be fully utilized.

[0005] Therefore, there is an urgent need for a steam heat exchanger specially designed for the steamer, which is simple and efficient in structure and can stably operate, to realize effective recycling of the pressure relief steam of the steamer, improve energy utilization rate, reduce negative impact on the environment, and meet the dual needs of modern production and environmental protection.

[0031] A barrel body 1 is provided with an inlet pipe 2 and an outlet pipe 3.

[0032] A steam inlet and outlet assembly comprises an air inlet manifold 4, an air outlet manifold 5, a circulating steam inlet pipe 6, a circulating steam outlet pipe 7 and an exhaust pipe 8, the circulating steam inlet pipe 6 and the circulating steam outlet pipe 7 are connected with the air inlet manifold through a tee joint one 9, and the exhaust pipe is connected with the air outlet manifold through a tee joint two 10.

[0033] A plurality of heat exchange pipes 11 are arranged along the height direction of the barrel body, one end of each heat exchange pipe is connected with the air inlet manifold, and the other end is connected with the air outlet manifold.

[0034] In the above technical solution, the inlet pipe and the outlet pipe on the barrel body are respectively used for the entry of cold water and the flow of hot water, and a channel for the entry of cold water and the flow of hot water is formed, so that the cold water can enter the barrel body smoothly to receive steam heat exchange and be converted into hot water output, forming a complete water heat exchange circulation system.

[0035] The steam inlet and outlet assembly realizes the effective connection of the circulating steam inlet pipe, the circulating steam outlet pipe and the air inlet manifold and the reasonable connection of the exhaust pipe and the air outlet manifold through specific pipeline layout and tee joints, ensures that the steam of the steam tank can enter the heat exchange process in an orderly manner, and can be discharged through the exhaust pipe when needed, and optimizes the recycling path and discharge control of the steam.

[0036] The plurality of heat exchange pipes arranged along the height direction of the barrel body greatly increase the contact area and heat exchange time of the steam and the cold water, significantly improve the steam heat exchange efficiency, and enable the heat of the steam to be fully transferred to the cold water to rapidly raise the water temperature.

[0037] Specifically, the barrel body is further provided with a blowdown pipe 12.

[0038] In the embodiment, the blowdown pipe arranged on the barrel body facilitates the periodic cleaning of the deposits such as dirt and impurities that may be generated in the heat exchange process in the barrel body, keeps the inside of the barrel body clean, prevents the accumulation of dirt from affecting the heat exchange efficiency and the performance of the equipment, prolongs the service life of the equipment, and ensures that the entire steam heat exchanger can operate continuously and stably.

[0039] Specifically, the air inlet manifold and the air outlet manifold are both rectangular covers, and the air inlet manifold and the air outlet manifold are arranged along the height direction of the barrel body.

[0040] In this embodiment, the inlet manifold and the outlet manifold are designed as a rectangular cover and arranged along the height direction of the barrel, which can better cover the heat exchange pipes, facilitate the connection of the chromium-plated heat exchange pipes, make the steam uniformly distributed around the heat exchange pipes, improve the uniformity of the contact between the steam and the heat exchange pipes, further improve the heat exchange effect, reduce the dead angle of steam flow, make the steam heat more fully utilized, and also facilitate the compact design of the overall structure of the equipment.

[0048] In the embodiment, the heat exchange pipe adopts the structural design of inner ring circular pipe, outer ring circular pipe and arc-shaped pipe, the flow path of steam in the heat exchange pipe and the contact area with cold water are increased, and the heat exchange effect of steam and the heat exchange pipe is strengthened. The connecting end one and the connecting end two on the outer ring circular pipe are respectively communicated with the air inlet manifold and the air outlet manifold, so that the steam can be efficiently circulated and heat exchanged in the heat exchange pipe, the heat exchange efficiency between the steam and the cold water in the barrel body is further improved, the cold water can be heated to the target temperature more quickly, and the heat exchange efficiency of the whole steam heat exchanger is improved.
