Negative pressure isolation platform and environment control method

Abstract

The negative pressure isolation platform comprises a main body platform arranged on the sea level, a negative pressure isolation area composed of a plurality of cabins is arranged on the upper surface of the main body platform, and a normal pressure activity area composed of a plurality of cabins is arranged on one side of the negative pressure isolation area. The internal environment control system of the negative pressure isolation area and the normal pressure activity area comprises a deep water circulation temperature control system and a differential pressure type fresh air system which are arranged on the main body platform. Deep cold water is extracted through a water pump and circulated to cold air pieces of all the cabins to achieve the cooling purpose, meanwhile, outside fresh air is cooled through a cooling coil set and then distributed to all the cabins, the negative pressure gradient and the airflow trend of the different cabins are controlled through variable air volume of an air outlet of the constant-temperature fresh air system, and cold water flowing in a pipeline does not make direct contact with air in all the cabins; the pollution risk of a traditional air conditioner air return pipeline is avoided, temperature control of all the cabins and fresh air temperature control are kept unified, pollutant diffusion caused by air convection due to the temperature difference between the cabins is avoided, and the system is more scientific and effective.

Description

technical field [0001] The invention relates to the technical field of marine platforms, in particular to a negative pressure isolation platform and an environmental control method. Background technique [0002] In recent years, the country has paid more and more attention to biosecurity and disease control. Sansha City is located in the southernmost part of my country, and the islands and reefs under its jurisdiction are located in the far sea. However, in the event of an epidemic, it will be more difficult to provide protection in the later stage. On the one hand, the medical conditions on the islands and reefs are limited, and on the other hand, the long-distance transportation of infected people back to the designated isolation sites on land is very risky. [0003] Therefore, there is an urgent need for a dedicated platform that can complete patient treatment on the spot. The South China Sea has been in a high temperature environment for a long time, and the environment...

AI Technical Summary

Problems solved by technology

[0004] The applicant aims at the traditional ship central air-conditioning system in the above-mentioned existing production technology. During the outbreak of an epidemic such as the new crown, the return air pipeline will easily cause the pollution of the whole ship, and convection will occur under the condition of heat exchange between the ward cabin and the cabin. , the disadvantage of easily causing the diffusion of pollutants, providing a negative pressure isolation platform and an environmental control method, thereby avoiding the pollution caused by the diffusion of pollutants and the return air pipeline of the air conditioner due to the air convection caused by the temperature difference between the cabins Risk, more scientific and effective control of the environment of the negative pressure isolation platform
