Description

Technical Field

[0001] This invention relates to a medical clean air conditioning auxiliary machine used in marine air conditioning and ventilation technology, and more particularly to a marine air conditioning and ventilation filtration device. Background Technology

[0002] Cleanroom air conditioning, as a special type of air conditioning engineering, has strict requirements for indoor air temperature, humidity, air velocity, pressure, and cleanliness. The most critical equipment in cleanroom air conditioning is the high-efficiency particulate air (HEPA) filter, whose function is to purify the air and ensure its cleanliness. Currently, HEPA filters are widely used in medical cleanrooms, clean factories, laboratories, and other places with high air quality requirements. HEPA filtration devices are an indispensable part of cleanroom air conditioning systems.

[0003] The installation space for HEPA filters needs to be comprehensively considered, taking into account factors such as location, size, environment, installation method, and compatibility with other equipment. To facilitate installation, maintenance, and replacement, HEPA filters require a relatively large installation space, including space for air inlets and outlets. However, in specialized applications such as cleanroom air conditioning systems on ships, the cabin space is typically narrow, and conventional HEPA filter designs have too low a space utilization rate to meet the actual ship installation requirements.

[0004] Therefore, when applied in confined spaces, such as in the marine industry, conventional high-efficiency filters have low space utilization rates, making it difficult to achieve good application in such marine fields and limiting the development of marine clean air conditioning technology. Summary of the Invention

[0005] The purpose of this invention is to integrate a high-efficiency filter, improve space utilization, and facilitate the integration of ship equipment, thereby providing a compact and high-efficiency filtration device.

[0006] To achieve the above objectives, the technical solution of the present invention is: a compact high-efficiency filtration device, which consists of two sets of high-efficiency filter devices connected by a connecting section to form a whole, which can effectively reduce the installation and maintenance space and meet the installation requirements of narrow spaces on special ships.

[0007] Furthermore, the high-efficiency filter device includes an outer casing and a high-efficiency filter. The high-efficiency filter is installed in the outer casing. The air inlet of the outer casing is connected to a flexible hose via a connecting flange, and the air outlet is equipped with a matching flange.

[0008] Furthermore, pressure measuring tubes are installed on the air inlet and air outlet of the outer casing.

[0009] Furthermore, the connecting section is located between the two high-efficiency filter units.

[0010] Furthermore, the high-efficiency filter is equipped with covers on both sides, which can be opened on either side during installation and maintenance to install or remove the high-efficiency filter.

[0011] Furthermore, a compact high-efficiency filter is arranged at the air outlet of the air conditioning unit, and the air is filtered and then sent to the corresponding cleanroom terminal through the air duct.

[0012] Furthermore, during use, the air conditioning unit supplies air through the two air inlets on the left side of the compact high-efficiency filter, and after passing through the high-efficiency filter, it exits through the corresponding air outlet on the right side and is sent into the air duct of the air conditioning system.

[0013] The beneficial effects of this invention are:

[0014] Compared with existing technologies, the main improvement of this invention lies in integrating two high-efficiency filters. The two sets of high-efficiency filters are connected by a connecting section, effectively reducing the installation space required for maintenance and meeting the installation needs of narrow spaces on special vessels. When installation, maintenance, or filter replacement is needed, either side of the side covers can be opened to install or remove the high-efficiency filter. The connecting section and the high-efficiency filter are connected by snap-fit ​​connections for easy disassembly. The connecting section serves to connect the two high-efficiency filters and prevent air leakage between the two air ducts. Furthermore, this device can be flexibly adjusted according to actual space conditions, either by hoisting with lifting lugs or by floor installation.

[0015] This invention realizes the miniaturization and integration of a ship's clean air conditioning system by integrating two or more high-efficiency filters, which is more adaptable to the special spatial environment requirements of ships and provides conditions for the application of ship air conditioning and ventilation technology.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 As shown in Figure 2, the embodiment of the present invention provides a compact high-efficiency filtration device, which consists of two sets of high-efficiency filter devices connected by a connecting section 8 to form a whole, which can effectively reduce the installation and maintenance space and meet the installation requirements of narrow spaces on special ships.

[0021] Each HEPA filter unit includes a flexible hose 1, a connecting flange 2, an outer casing 3, an HEPA filter 4, front and rear cover plates 5, a pressure testing tube 6, and a mating flange 7. The HEPA filter 4 is installed inside the outer casing 3. Front and rear cover plates 5 are located on both sides of the HEPA filter 4. The air inlet of the outer casing 3 is connected to the flexible hose 1 via the connecting flange 2, and the air outlet is equipped with a mating flange 7. Pressure testing tubes 6 are installed on both the air inlet and outlet of the outer casing 3.

[0022] During operation, the air conditioning unit supplies air through the two inlets on the left side of the compact high-efficiency filter, and after passing through the high-efficiency filters, it exits through the corresponding outlets on the right side, thus entering the air conditioning system ductwork. Connecting section 8 is located between the two high-efficiency filter units; during installation and maintenance, either side of the cover can be opened to install or remove the high-efficiency filter. Pressure measuring pipes 6 are located at the air inlet and outlet, used to monitor the inlet and outlet air pressure.

[0023] The compact high-efficiency filter device of this invention is arranged at the air outlet of the air conditioning unit. After filtration, the air is delivered to the corresponding cleanroom terminal through the air duct. When the air outlets are densely packed, the compact high-efficiency filter device of this invention can effectively improve space utilization and solve the problem of space constraints.
