Modular working-condition-variable medical air purifying system

Abstract

The invention relates to a modular working-condition-variable medical air purifying system which comprises a medical air exhaust and fresh air integrated cabinet, a uniform air mixing and air supplying ceiling and a return air treater. The medical air exhaust and fresh air integrated cabinet is used for treating and outputting input fresh air and to-be-exhausted air, the uniform air mixing and air supplying ceiling is used for uniformly mixing, filtering and outputting introduced fresh air in a form of weak turbulence, and the return air treater is used for purifying, filtering and outputting return air. By utilizing the air purifying system postoperative infection rate can be lowered obviously, energy consumption can be lowered greatly, and building cost, building period and space requirements (needlessness of special machine room, few valves and short air pipe) of an operation room can be lowered remarkably at the same time. In addition, the invention further relates to the corresponding operation room.

Description

technical field [0001] The present invention generally relates to the field of medical ventilation facilities, and in particular relates to a modular variable working condition medical 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] At present, mainstream medical ventilation facilities use unidirectional flow clean technology. Unidirectional flow, also known as "laminar flow", refers to the airflow passing through the air pu...

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
