Description

Technical Field

[0001] This utility model relates to the field of fresh air devices, and in particular to a water-cooled general-purpose fresh air device. Background Technology

[0002] With increasing attention to occupational health, new factories have higher and higher requirements for the production workshop environment, among which indicators such as dust volume, temperature, and air cleanliness are particularly important. Traditional air conditioning systems can provide clean air, ensuring that the fresh air delivered into the production workshop meets the standards in terms of dust volume, temperature, and air cleanliness. However, individual air conditioners have problems such as high energy consumption, small service area, and high project costs. For larger production workshops, multiple air conditioners are needed to meet the air supply needs. For many factories, the high cost of engineering and high energy consumption during use makes it difficult to promote the use of air conditioning systems.

[0003] Most of them use simple fans to supply air into the production workshop, and correspondingly exhaust fans to exhaust the air from the production workshop to the outside. This improves the air circulation effect in the production workshop, but it does almost no treatment on the outside air, especially in densely populated industrial plant areas where the outside air quality is not ideal. The supplied fresh air cannot meet the standards in terms of dust content, temperature, and air cleanliness.

[0004] Some systems add a filter device (usually a replaceable filter cotton) to the outside of the fan's air intake side. This filters out some dust from the outside air before it enters the fan. The cleanliness of the incoming fresh air is improved by replacing the filter cotton regularly. However, the incoming air is at room temperature, and especially in hot weather when the outside air temperature is significantly higher than the indoor temperature, the incoming fresh air is not comfortable. Moreover, for modern factories, it is still difficult to meet the standards in terms of dust content, temperature, and air cleanliness.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a water-cooled universal fresh air device. Compared with the traditional air conditioning system, it has advantages such as low energy consumption and low engineering cost. Compared with the traditional dust removal and fan-based air intake system, it reduces the intake air temperature and cleanliness, and can adjust the air humidity as needed, so that the fresh air delivered to the production workshop has a suitable temperature and humidity and is clean. One or more devices can be installed depending on the service area, making it suitable for widespread application.

[0011] A dry filter unit includes multiple layers of filter cotton stacked in the left-right direction; the left and right ends of the dry filter unit are respectively provided with a third air inlet and a third air outlet.

[0012] The negative pressure fan unit, which serves as the power unit for the fresh air device, has a fourth air inlet and a fourth air outlet on its left and right ends, respectively.

[0013] The circulating water collection tank includes a liquid receiving cavity; the top of the liquid receiving cavity is connected to the bottom of the water flow perforated plate cooling unit, the baffle plate demisting unit, the dry filtration unit, and the negative pressure fan unit, respectively, so that the liquid from the four units falls downward into the liquid receiving cavity;

[0014] External gas enters through the first air inlet, is cooled by the liquid sprayed by the atomizing spray system, and then flows out through the first air outlet and enters the baffle demisting unit through the second air inlet. After being demisted by the baffle demisting unit, the gas flows out through the second air outlet and enters the dry filter unit through the third air inlet. After being filtered by the dry filter unit, the gas flows out through the third air inlet and enters the negative pressure fan unit through the fourth air inlet, and then fresh air is blown out through the fourth air outlet.

[0015] As a preferred embodiment, the guide plates are arranged in an alternating vertical and horizontal orientation, and their guide holes are connected in both the vertical and horizontal directions, so that the liquid in the water flow plate cooling unit is transported from top to bottom, while the gas is transported horizontally from the outside to the inside through the first air inlet, the guide holes, and the first air outlet.

[0016] As a preferred embodiment, the folding plate assembly includes several V-shaped folding plates with staggered upper and lower stacking intervals, forming a V-shaped gap between the upper V-shaped folding plate and the lower V-shaped folding plate, and the second air inlet and the second air outlet are connected through the V-shaped gap.

[0017] As a preferred embodiment, the folding plate group is provided with two sets of folding plates spaced apart in the left and right directions, and the V-shaped folding plates of the two sets of folding plate groups face opposite directions, so that the V-shaped gaps are connected to form a Z-shaped gap.

[0018] As a preferred embodiment, the water flow perforated plate cooling unit, the baffle plate demisting unit, and the dry filtration unit are all configured as cuboid modules, which are sequentially matched and assembled at the first air outlet, the second air inlet, the second air outlet, and the third air inlet.

[0023] As a preferred embodiment, an air humidity detector is provided at the fourth air inlet of the negative pressure fan unit.

[0024] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly consists of a water flow perforated plate cooling unit, a baffle plate demisting unit, a dry filtration unit, a negative pressure fan unit, and a circulating water collection tank. The water flow perforated plate cooling unit, the baffle plate demisting unit, the dry filtration unit, and the negative pressure fan unit are located at the top of the circulating water collection tank, thus forming an energy-saving water-cooled universal fresh air device. The liquid from the water flow perforated plate cooling unit, the baffle plate demisting unit, the dry filtration unit, and the negative pressure fan unit falls downward into the liquid receiving chamber. The liquid sprayed down by the external gas atomization spray system is cooled. The cooled gas is demisted by the baffle plate demisting unit and then enters the dry filtration unit. After being filtered by the dry filtration unit, it enters the negative pressure fan unit and then blows out fresh air. Compared to traditional air conditioning systems, this technology offers advantages such as low energy consumption and low construction costs. Compared to traditional dust removal and fan-based air intake systems, it reduces intake air temperature and cleanliness, and allows for adjustable air humidity, ensuring that the fresh air delivered to the production workshop has suitable temperature and humidity and is clean. Furthermore, one or more systems can be installed depending on the service area, making it suitable for widespread application.

[0031] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0032] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] A water-cooled universal fresh air device includes a water flow perforated plate cooling unit 10, a baffle plate demisting unit 20, a dry filter unit 30, a negative pressure fan unit 40, and a circulating water collection tank 50. The water flow perforated plate cooling unit 10, the baffle plate demisting unit 20, the dry filter unit 30, and the negative pressure fan unit 40 are arranged sequentially along the air supply direction and are located on top of the circulating water collection tank 50.

[0034] The water flow perforated plate cooling unit 10 includes a multi-stage guide plate 11 with guide holes 111 and an atomizing spray system 12 disposed on its top. The left and right ends of the water flow perforated plate cooling unit 10 respectively have a first air inlet and a first air outlet. In this embodiment, the water flow perforated plate cooling unit 10 is designed to reduce the intake air temperature and cleanliness of the fresh air system. It can remove suspended particles from the outdoor air, lower the intake air temperature, and ensure that the temperature of the fresh air supplied to the workshop by the fresh air system is suitable. It can also regulate air humidity. The guide plates 11 can be made of stainless steel; for ease of processing, a set of vertically inclined guide plates 11 is used.

[0035] The folding plate defogging unit 20 includes a folding plate assembly 21; the left and right ends of the folding plate defogging unit 20 are respectively provided with a second air inlet and a second air outlet;

[0036] The dry filter unit 30 includes multiple layers of filter cotton stacked in the left-right direction (preferably replaceable, with a replacement port on the outer periphery for opening a small door panel to replace the filter cotton); the left and right ends of the dry filter unit 30 respectively have a third air inlet and a third air outlet; preferably, a W-shaped dry filter cotton is used to further absorb water mist and particulate matter in the air, ensuring the humidity and cleanliness of the incoming air in the fresh air system. The multiple layers of W-shaped dry filter cotton can adopt a gradient density structure, for example, the density of the filter cotton near the air inlet side is slightly smaller than that near the air outlet side, forming a design where the density gradually increases from the air inlet side to the air outlet side, realizing multi-stage filtration function within the same dry filter unit 30, ensuring air intake effect, and at the same time helping to extend the service life of each layer of filter cotton and reduce consumable replacement costs. In contrast, in traditional technology, one or more layers of filter cotton of the same specification are used in the filter unit. If the density is slightly lower, the filtration effect on small particles is not good; if the density is slightly higher, it is easy to be clogged by large particles.

[0037] The negative pressure fan unit 40, serving as the power unit of the fresh air device, provides air supply power. Its left and right ends are respectively configured as the fourth air inlet and the fourth air outlet. It can employ a paddle-type negative pressure fan, characterized by low energy consumption, low speed, low noise, and large air volume. The negative pressure fan unit 40 includes a silent negative pressure fan 42 and a protective frame surrounding the silent negative pressure fan 42. The fourth air inlet is located at the end of the protective frame, and the end of the protective frame is matched and assembled with the third air outlet of the dry filter unit 30.

[0038] The circulating water collection tank 50 includes a liquid receiving cavity; the top of the liquid receiving cavity is connected to the bottom of the water flow perforated plate cooling unit 10, the baffle plate demisting unit 20, the dry filter unit 30, and the negative pressure fan unit 40 respectively, so that the liquid from the four units falls downward into the liquid receiving cavity; the circulating water collection tank 50 shown in the figure is rectangular, but in actual design and manufacturing, it is not limited to this, and a conical water collection tank with a larger top and a smaller bottom is preferred.

[0039] During operation, external gas enters through the first air inlet, is cooled by the liquid sprayed by the atomizing spray system 12, and the cooled gas flows out through the first air outlet and enters the baffle demisting unit 20 through the second air inlet. After being demisted by the baffle demisting unit 20, the gas flows out through the second air outlet and enters the dry filter unit 30 through the third air inlet. After being filtered by the dry filter unit 30, the gas flows out through the third air inlet and enters the negative pressure fan unit 40 through the fourth air inlet, and then fresh air is blown out through the fourth air outlet.

[0040] like Figure 2 As shown, the guide plates 11 are arranged in a staggered, vertically inclined manner, and their guide holes 111 are connected in both the vertical and horizontal directions, allowing the liquid in the water flow plate cooling unit 10 to be transported from top to bottom, while the gas is transported horizontally from the outside to the inside through the first air inlet, the guide holes 111, and the first air outlet. Because the guide plates 11 are inclined, there is an overlapping area between the upper and lower layers of guide plates 11. Their guide holes 111 are opened perpendicular to the inclined plane of the guide plate 11, with an inclination angle preferably around 45 degrees, satisfying the connectivity requirements in both the vertical and horizontal directions. The diagram shows two sets of guide plates 11, with the areas of the two sets of guide plates 11 overlapping, thus forming a grid-like pattern.

[0041] like Figure 3 As shown, the folding plate assembly 21 includes several V-shaped folding plates 211 stacked vertically and alternately spaced. A V-shaped gap 212 is formed between the upper and lower V-shaped folding plates 211, and the second air inlet and the second air outlet are connected through the V-shaped gap 212. For applications requiring high defogging performance, a nano-hydrophobic coating can be applied to the surface of the folding plates to reduce water adhesion. Furthermore, the folding plate assembly 21 is arranged in two groups along the left-right direction, with the V-shaped folding plates 211 facing opposite directions, resulting in corresponding Z-shaped gaps. Further, the folding plate assembly 21 near the second air inlet can be designated as the first group, with a slightly smaller V-shaped gap, while the folding plate assembly 21 near the second air outlet can be designated as the second stage, with a slightly larger V-shaped gap, creating a two-stage defogging effect. The first stage removes relatively more water mist, while the second stage further removes water mist, improving the overall defogging effect of the folding plate defogging unit 20. Utilizing the principle of folding plate defogging, the dual-stage folding plate defogging system in the middle can effectively remove water mist carried out by the water flow perforated plate cooling unit 10. The folding plates are made of corrosion-resistant, high-quality 316 stainless steel, which is stable and durable.

[0042] Typically, the water flow perforated plate cooling unit 10, the baffle plate demisting unit 20, and the dry filter unit 30 are all configured as cuboid modules, which are sequentially matched and assembled through the first air outlet, the second air inlet, the third air outlet, and the fourth air inlet. This modular design improves versatility, enhances system stability, and facilitates maintenance. During construction and application, different baffle plate demisting units 20, dry filter units 30, and fans can be selected according to the needs of different production workshops. Furthermore, it is necessary to select appropriate baffle plate demisting units 20 and dry filter units 30 for different ambient air qualities. Depending on the size and space of the production workshop, one or more water-cooled universal fresh air units can be installed.

[0043] The negative pressure fan unit 40 is equipped with a fresh air guide bend 41 at the fourth air outlet. The fresh air guide bend 41 is bent downwards and extends downwards, so that the water-cooled universal fresh air unit provides downward-flowing fresh air to production workshops and other places. Usually, the fresh air guide bend 41 is at a relatively high height. This downward-flowing fresh air optimizes the airflow distribution and is more conducive to the air flow in the production workshop. It can greatly improve the air environment in the factory workshop and improve the comfort of the staff in the workshop.

[0044] like Figure 4 As shown, the circulating water collection tank 50 is connected to a reuse pipe 51, which is connected to the atomizing spray system 12 as an auxiliary water source for the atomizing spray system 12. Specifically, at least two water sources can be connected to the inlet end of the water pump of the atomizing spray system 12: tap water supply and reuse pipe 51. A switch valve is installed between the reuse pipe 51 and the inlet end of the water pump to selectively open and close the water supply of the reuse pipe 51. Normally, during the working hours of the production workshop, the inlet end of the water pump of the atomizing spray system 12 is mainly supplied with tap water, while the circulating water collection tank 50 is in a water collection state. During non-working hours (at night), the water in the circulating water collection tank 50 is in a static state. When the water-cooled universal fresh air device is working the next day, the settled sewage at the bottom of the circulating water collection tank 50 is first drained, and then the switch valve is opened to activate the reuse pipe 51 and circulate the water in the circulating water collection tank 50. The circulating water collection tank 50 is equipped with a self-cleaning filter and a water level sensor. The water-cooled universal fresh air device also includes a control box, which is electrically connected to the atomizing spray system 12 and the negative pressure fan unit 40. An air humidity detector is installed at the fourth air inlet of the negative pressure fan unit 40. Specifically, the control box is electrically connected to the water pump, multiple switching valves (different switching valves are used for the reuse pipe 51 and the tap water supply), the water level sensor, and the air humidity detector. It can activate different water supply sources according to the water level and adjust the air humidity according to the air conditions of different seasons and human needs (adjusting the spray volume of the atomizing spray system 12, the fan speed of the negative pressure fan unit 40, and dynamically adjusting the air humidity based on the real-time air humidity detected by the air humidity detector).

[0045] like Figure 5 As shown, in other embodiments, the liquid in the circulating water collection tank 50 can be discharged, treated by the purification device 52, and then enter the water supply end of the atomizing spray system 12, thus forming a closed circulating water system.

[0046] It is evident that this type of water-cooled general-purpose fresh air unit can be further upgraded to an intelligent control device to better meet the higher requirements of some new factories. Even though the cost increases due to the improvement of intelligence, it still has an absolute advantage over air conditioning systems in terms of engineering cost and operating cost.

[0047] The key design feature of this utility model lies in the arrangement of a water flow perforated plate cooling unit 10, a baffle plate demisting unit 20, a dry filtration unit 30, a negative pressure fan unit 40, and a circulating water collection tank 50. These four units are located at the top of the circulating water collection tank 50, thus forming an energy-saving water-cooled universal fresh air device. The liquid from the water flow perforated plate cooling unit 10, the baffle plate demisting unit 20, the dry filtration unit 30, and the negative pressure fan unit 40 falls downwards into the liquid receiving chamber. The liquid is cooled by the external gas atomizing spray system 12. The cooled gas is then demisted by the baffle plate demisting unit 20 and enters the dry filtration unit 30. After being filtered by the dry filtration unit 30, it enters the negative pressure fan unit 40 and is then blown out as fresh air. Compared to traditional air conditioning systems, this technology offers advantages such as low energy consumption and low construction costs. Compared to traditional dust removal and fan-based air intake systems, it reduces intake air temperature and cleanliness, and allows for adjustable air humidity, ensuring that the fresh air delivered to the production workshop has suitable temperature and humidity and is clean. Furthermore, one or more systems can be installed depending on the service area, making it suitable for widespread application.

[0048] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
