Low-noise modular air purification system

Abstract

The invention relates to a low-noise modular air purification system. The low-noise modular air purification system comprises a medical exhaust air and fresh air integrated cabinet, a return air processing and air supply ceiling and return air ports, wherein the medical exhaust air and fresh air integrated cabinet is used for feeding fresh air and to-be-exhausted air and exhausting the fresh air and the to-be-exhausted air after processing; the return air processing and air supply ceiling is used for evenly mixing, purifying and filtering the introduced fresh air and return air and exhausting the mixed air in a light turbulence mode; and a medical room and a return air channel communicate through the air return ports so that the return air can be introduced into the return air processing and air supply ceiling. The low-noise modular air purification system can remarkably decrease the rate of postoperative infection and greatly reduce energy consumption; meanwhile, through highly integrated equipment and the modular installation mode, the construction cost and complexity are remarkably reduced, so that the construction cost of operating rooms is remarkably reduced, and the construction period of operating rooms is remarkably shortened; due to the facts that no special machine room or return air pipeline is required and the number of valves is small, the space requirements are reduced remarkably; and besides, noise can be remarkably lowered on the premise that sufficient air volume is ensured.

Description

technical field [0001] The present invention generally relates to the field of medical ventilation facilities, in particular to a low-noise modular air purification system and a corresponding operating room. Background technique [0002] Today, there are about 25,000 hospitals in our country. Since about 40% of these hospitals were built in 1980, their medical conditions can no longer meet the requirements of modern medical care, so there are urgent and large-scale improvement and expansion tasks. How to reduce the cost of reconstruction and expansion is a significant goal. In addition, the medical industry is related to the life and health of the people. How to shorten the construction period of the hospital is also an important task. [0003] As the requirements for the medical environment increase, the medical air purification system is also developing in the direction of high power and large air volume. However, an important factor restricting this development trend is...

Problems solved by technology

If the mixing is uneven, it will directly affect the air quality of the output wind, for example, the oxygen content of the local output wind is low or the temperature is high

However, due to the treatment of dehumidification, temperature adjustment, humidification and purification, the fresh air often has a significantly higher pressure head (or wind pressure) and a correspondingly higher wind speed than the return air. When wind mixing, it is difficult to achieve uniform mixing

However, if the two are mixed in advance in the front pipeline, firstly, a longer mixing pipeline is required, and secondly, the high-pressure head fresh air is likely to hinder the forward flow of the low-pressure head circulation air, and even cause the low-pressure head circulation air to flow backward, that is, the so-called "Air blockage" phenomenon

Therefore, in the prior art, it is generally avoided to directly combine the conveying pipelines of fresh air and circulating air with large difference in transmission pressure head, but first adjust their pressure heads and then merge the two transmission pipelines, which also leads to significant increased cost
