Description

Technical Field

[0001] This utility model relates to a single-effect regenerative dehumidifier box, belonging to the technical field of dehumidification devices. Background Technology

[0002] In many food processing industries, steam ovens are commonly used equipment for processing food using steam. During steam oven operation, the steam inlet temperature is typically between 100 and 150°C. However, during food production, a large amount of steam inevitably overflows from the steam oven; this overflowing steam generally has a temperature between 50 and 75°C. This overflowing steam has several adverse effects on the food production workshop, such as:

[0003] 1. Obstructed vision: The steam filling the workshop can seriously interfere with the workers' vision, reduce work efficiency, and increase the risk of operational errors. Especially in some production processes that require delicate operations, poor visibility may lead to a decline in product quality or even production accidents.

[0004] 2. Hygiene Hazards: Steam will condense into water droplets on surfaces such as walls, ceilings, and floors in the workshop. This damp environment provides a breeding ground for bacteria, easily leading to hygiene problems, affecting food quality and safety, and failing to meet hygiene standards for the food processing industry.

[0005] 3. Safety hazards: Water droplets condensing inside and outside electrical equipment may cause electrical short circuits and other malfunctions, leading to fires, electric shocks and other safety accidents, posing a serious threat to the lives of workers and the safety of workshop property.

[0006] Therefore, developing a dehumidification device that can effectively handle steam overflow from steam ovens and solve the above-mentioned problems is of great practical significance. Utility Model Content

[0007] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a single-effect regenerative dehumidification box that can effectively handle the high-temperature and high-humidity steam overflowing from the steam oven, prevent the steam from spreading and condensing in the workshop, and eliminate problems such as obstructed vision, hygiene hazards and safety hazards caused by steam.

[0008] The single-effect regenerative dehumidification box of this utility model includes a unit shell, with an air inlet and a steam inlet at one end and an air outlet at the other end; a plate heat exchanger is installed inside the unit shell, which is composed of multiple layers of vertically arranged metal plates. The multiple layers of metal plates are staggered to form two mutually perpendicular channels, which serve as a steam channel and an air channel, respectively. The air channel connects the air inlet and the air outlet, and the steam channel connects the steam inlet and the air outlet.

[0009] Inside the unit casing, a mixing chamber is provided after the plate heat exchanger. After the gas exits the plate heat exchanger, it is mixed in the mixing chamber and then discharged from the outlet.

[0010] Furthermore, on the unit casing, the air inlet is at the top and the steam inlet is at the bottom.

[0011] Preferably, an upper guide plate and a lower guide plate are provided at the upper and lower positions of the mixing chamber, respectively. The upper guide plate guides the gas passing through downwards, and the lower guide plate guides the gas passing through upwards.

[0012] The plate heat exchanger of this utility model is provided with a water receiving tray at the bottom.

[0013] The water receiving tray is connected to the external drainage pipe through the drain outlet.

[0014] The advantages of this utility model compared with the prior art are:

[0015] Effective dehumidification: The plate heat exchanger uses ambient temperature air in the workshop to cool the high temperature and high humidity steam overflowing from the steam oven, causing the moisture in the steam to condense and be collected and discharged through a water collection pan. This effectively reduces the humidity of the steam and avoids the hygiene and safety hazards caused by steam condensation in the workshop.

[0016] Steam dilution: The two airflows mix in the mixing chamber, and the mixed air dilutes the moisture in the steam, further enhancing the effect of eliminating fog.

[0017] Reasonable structure: The air inlet is at the top and the steam inlet is at the bottom. After flowing out of the plate heat exchanger, the air and steam exchange positions. Combined with the upper and lower guide plates in the mixing chamber, it is conducive to the full mixing of air and steam in the mixing chamber and improves the mixing effect.

[0021] The present invention will be further described below with reference to specific embodiments.

[0022] The description of this utility model is merely a structural or even functional description of the embodiments, and the scope of this utility model is not limited by the embodiments described herein.

[0023] This embodiment is achieved through the following technical solution: a single-effect regenerative dehumidifier box, which is connected to other equipment such as steam ovens in the place of use for dehumidification in food workshops.

[0024] like Figure 1 , 2 As shown, it includes a unit casing 1, with an air inlet 4 and a steam inlet 5 at one end and an outlet 8 at the other end. A plate heat exchanger 2 is installed inside the unit casing 1. The plate heat exchanger 2 consists of multiple layers of vertically arranged metal plates, which intersect to form two mutually perpendicular channels, serving as a steam channel and an air channel respectively. The air channel connects the air inlet 4 and the outlet 8, and the steam channel connects the steam inlet 5 and the outlet 8. A sealing plate 3 is installed between the plate heat exchanger 2 and the unit casing 1, forming three enclosed areas: area A at the upper left, area B at the lower left, and area C on the right. Area C serves as a mixing chamber after the plate heat exchanger 2, with an upper guide plate 9 and a lower guide plate 10 positioned above and below it, respectively. The upper guide plate 9 guides the gas downwards, and the lower guide plate 10 guides the gas upwards.

[0025] Among them, on the unit casing 1, the air inlet 4 is on top and the steam inlet 5 is on the bottom.

[0026] In this embodiment, a water receiving tray 6 is provided below the plate heat exchanger 2, and the water receiving tray 6 is connected to the external drainage pipeline through the drain outlet 7.

[0027] The dehumidification principle of this invention is as follows:

[0028] High-temperature, high-humidity steam overflowing from the steam oven enters Zone A through steam inlet 5, while ambient-temperature natural air from the workshop enters Zone B through air inlet 4. Plate heat exchanger 2 is a plate sensible heat exchanger, which is made of multiple layers of aluminum foil. The multiple layers of aluminum foil are interlaced to form two channels. Air from Zone A and steam from Zone B each flow through one channel and pass through the plate sensible heat exchanger. Because the air temperature is lower than that of the steam, the air cools the steam and precipitates the moisture in the steam. The precipitated moisture is collected by water receiving pan 6 and discharged from the unit through drain outlet 7.

[0029] The mixed air dilutes the moisture in the steam, thus enhancing the effect of eliminating fog. The mixed gas flows out of the unit from the outlet 8.

[0030] Air inlet 4 is at the top and steam inlet 5 is at the bottom. After flowing out of plate heat exchanger 2, the air and steam exchange positions. That is, after flowing into the mixing chamber, the relatively lower temperature steam is located in the upper part of the mixing chamber, and the relatively higher temperature air is located in the lower part of the mixing chamber. With the help of the guide plate, it is conducive to their full mixing.

[0031] This application uses a natural cold source to dehumidify the steam overflowing from the steam oven, avoiding safety and pollution problems caused by disorderly steam discharge, and can collect the water extracted from the steam as greywater, which can be directly discharged or reused.

[0032] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
