Problems solved by technology

[0004] However, the shortcomings of this laminar flow device are also obvious. First, because the 9,000 cubic meters of clean air volume per hour required for 100-level purification is to ensure the air volume, overlapping noises are generated when these air volumes flow into the laminar flow box. , these noises will affect the mood of the medical staff in a closed operating environment and cause mental fatigue; second, because the clean air will bring out some bacteria in the boxes in the laminar flow box when it is blown into the laminar flow box

Embodiment 1

[0029] Such as Figure 1-5 As shown in , a combined low-noise 100-level laminar flow system includes a mixed flow box 1, the air supply duct 4 for air supply is connected to both sides of the mixed flow box 1, and the middle part of the mixed flow box 1 is provided with a vertically penetrating mixed flow box 1 The shadowless lamp sleeve 5, the bottom of the mixed flow box 1 is provided with a flow equalization layer 3 that can evenly distribute the air flow, and a hose 6 with the same diameter as the air supply pipe 4 is provided between the air supply pipe 4 and the mixed flow box 1. A small cylinder 11 is installed horizontally on the top of the air duct 4, and a horizontal guide rail 13 is installed on the top of the mixed flow box 1 near the hose 6;

[0030] On both sides of the shadowless lamp sleeve 5 in the mixed flow box 1, with the top surface and the vertical surfaces on both sides of the shadowless lamp sleeve 5 as the right-angle sandwiching surface, there are sou...

Embodiment 2

[0041] After removing the inner microporous sound-absorbing panel on the basis of Example 1, it was 45 decibels in a steady state, and the time to reach 50 decibels was compared with that of the prior art. figure 1 The middle device shortens the time by about 20%.

Embodiment 3

[0043] On the basis of Example 1, after the sound-absorbing filling material and the flexible mesh layer are removed, it is 46 decibels in a steady state, and the time to reach 50 decibels is compared with that of the prior art. figure 1 The middle device shortens the time by about 20%.

Abstract

The invention belongs to the technical field of operating room laminar flow air supply, and particularly relates to a combined type low-noise hundred-class laminar flow system. A hose is arranged between an air supply pipeline and a flow mixing box, wherein the diameter of the hose is the same as that of the air supply pipeline. A small-size air cylinder is horizontally installed at the top inside the air supply pipeline. A horizontal guide rail is installed at the top, close to one side of the hose, of the flow mixing box. Sound-absorbing filling materials, flexible net layers, inner micropore sound-absorbing plates and outer micropore sound-absorbing plates are sequentially arranged in the positions, on the two sides of a shadowless lamp sleeve, inside the flow mixing box. Efficient filters are uniformly distributed above a flow homogenizing layer. Compared with the prior art, the combined type low-noise hundred-class laminar flow system has the following advantages that the states of the outer micropore deflectors are adjusted, the effect that new noise is not produced in a stable state can be ensured meanwhile rapid silencing can be achieved, airflow is properly guided meanwhile noise is effectively reduced, and the combined type low-noise hundred-class laminar flow system is reasonable in overall design, good in silencing effect, high in practicability and suitable for application and popularization.

Description

technical field [0001] The invention belongs to the technical field of laminar flow air supply for operating rooms, and in particular relates to a combined low-noise 100-level laminar flow system. Background technique [0002] According to the "National Standard of the People's Republic of China" GB50333-2013 Hospital Clean Operating Room Building Technical Specifications, the laminar flow operating room laminar flow (class 100) area is 2400m×2600m×600m, that is, 6.24m³; and 6.24 square meters must be guaranteed The cleanliness in the area meets the requirements of Class 100 purification; the actual air supply volume must reach 9000m³ / n constant temperature and humidity air-conditioning air to meet the cleanliness requirements (the maximum average concentration of bacteria is 0.2 / 30min·Φ90 dishes), and the requirements reach above standards. [0003] At present, the common solutions in the industry are as follows: figure 1 (side view), including the mixed flow box 1', the ...
