Description

Technical Field

[0001] The utility model relates to a medical clean air-conditioning auxiliary machine used in ship air-conditioning and ventilation technology, in particular to a ship air-conditioning and ventilation filtering device. Background Art

[0002] Cleanroom air conditioning, a special type of air conditioning system, has strict requirements for indoor air temperature, humidity, wind speed, pressure, and cleanliness. The most critical equipment in cleanroom air conditioning is the HEPA filter, which purifies the air and ensures cleanliness. Currently, HEPA filters are widely used in medical cleanrooms, cleanroom factories, laboratories, and other places with high air quality requirements. HEPA filtration devices are an indispensable component of cleanroom air conditioning systems.

[0003] The installation space for HEPA filters requires comprehensive consideration of multiple factors, including location, size, environment, installation method, and other equipment. To facilitate installation, maintenance, and replacement, HEPA filters require a larger installation area, requiring space for both inlet and outlet ports. However, in specialized marine clean air conditioning applications, where cabin space is typically limited, conventional HEPA filters offer limited space utilization and are therefore unsuitable for onboard installation.

[0004] Therefore, when used in confined spaces, such as ships, conventional high-efficiency filters have low space utilization and are difficult to be well applied in such ship fields, which limits the development of ship clean air-conditioning technology. Summary of the Invention

[0005] The purpose of the utility model is to integrate a high-efficiency filter, improve space utilization, facilitate the integration of ship equipment, and provide a compact and high-efficiency filtering device.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is: a compact high-efficiency filtering device, which is composed of two groups of high-efficiency filter devices connected by a connecting section to form a whole, which can effectively reduce the installation and maintenance space; the high-efficiency filter device includes an outer box body and a high-efficiency filter, and the high-efficiency filter is installed in the outer box body. The air inlet of the outer box body is connected to the flexible hose through a connecting flange, and the air outlet is provided with a matching flange.

[0007] Furthermore, pressure measuring tubes are provided on the air inlet and the air outlet of the outer box body.

[0008] Furthermore, the connecting section is located between the two high efficiency filter devices.

[0009] Furthermore, cover plates are provided on both sides of the high efficiency filter, which are used to open any one of the cover plates on both sides during installation and maintenance to install or remove the high efficiency filter.

[0010] Furthermore, the compact high-efficiency filtering device is arranged at the air outlet of the air-conditioning unit, and the air outlet of the compact high-efficiency filtering device is connected to the end of the corresponding clean room through an air duct.

[0011] The beneficial effects of the utility model are:

[0012] Compared with the prior art, the present invention's main improvement lies in the integration of two high-efficiency filters. The two sets of high-efficiency filters are connected via a connecting section, effectively reducing the installation and maintenance space required to meet the narrow space installation requirements on special ships. When it is necessary to install, repair, or replace the filter, either side of the cover can be opened to install or remove the high-efficiency filter. The connecting section and the high-efficiency filter are connected with a snap-fit ​​connection for easy disassembly. The connecting section serves to connect the two high-efficiency filters and prevent cross-flow between the two air ducts. Furthermore, this device can be hoisted or installed on the ground via a lifting lug, allowing for flexible adjustment based on actual space conditions.

[0013] The utility model realizes the miniaturization and integration design of the ship's clean air-conditioning system, integrates two or more high-efficiency filters, better adapts to the special space environment requirements of the ship, and provides conditions for the application of ship air-conditioning and ventilation technology.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown in FIG2 , a compact high-efficiency filtering device provided by an embodiment of the present invention is composed of two groups 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 narrow space installation requirements on special ships.

[0019] Each HEPA filter unit comprises a flexible hose 1, a connecting flange 2, an outer housing 3, a HEPA filter 4, front and rear covers 5, a pressure measuring tube 6, and a matching flange 7. The HEPA filter 4 is mounted within the outer housing 3, flanked by front and rear covers 5. The air inlet of the outer housing 3 is connected to the flexible hose 1 via the connecting flange 2, and the air outlet is provided with a matching flange 7. Pressure measuring tubes 6 are provided at both the air inlet and outlet of the outer housing 3.

[0020] During operation, air from the air conditioning unit enters through the two air inlets on the left side of the compact HEPA filter unit, passes through the HEPA filters, and exits through the corresponding air outlet on the right side, where it is fed into the air conditioning system duct. A connecting section 8 is located between the two HEPA filter units. During installation and maintenance, either side of the cover can be opened to install or remove the HEPA filters. Pressure gauges 6 are located at the air inlet and outlet to monitor the inlet and outlet pressures.

[0021] This compact, high-efficiency filter device is placed at the air outlet of the air conditioning unit. After filtering, the air is delivered to the end of the corresponding clean room through the air duct. When the air outlets are densely packed, using this compact, high-efficiency filter device can effectively improve space utilization and solve the problem of space shortage.
