How does positive pressure container work?

2/12/2023

 
Land-based oil exploration and offshore platform oil exploration areas have the potential to produce explosive gases, and for areas where fires and explosions may occur are known as hazardous areas and are generally divided into three zones - Zone 0, Zone 1, and Zone 2. Modern drilling and exploration sites require strict explosion-proof performance of the equipment on site, so TLS provides the perfect solution with positive pressure explosion-proof containers.
 
The principle of the positive pressure explosion-proof container is to achieve explosion-proof technical requirements through the container shell, so that all the regular non-explosion-proof machinery installed in the container achieve the purpose of explosion-proof.
 
The positive pressure ventilation system is the key to making the container explosion-proof. When the total power supply is turned on, firstly the system automatically turns on the explosion-proof blast system. The explosion-proof centrifugal fan extracts fresh air from 30 meters outside the danger zone into the positive pressure container. The air in the positive pressure container is purged and a positive pressure of more than 50pa is established. The total power supply is automatically turned on when the control conditions are met, then the power supply can be turned on to control the power supply and turn on other electrical equipment in the positive pressure container.
 
In the process of turning on or in the operation of the equipment in the container, if the explosion-proof control system monitors the presence of dangerous gases in the container or fails to reach the corresponding positive pressure, the alarm system will alarm and warn, and if the control conditions in the container are still not met within the specified time, or if the alarm limits are reached directly, the non-explosion-proof control system in the container will be closed automatically, so as to achieve the purpose of explosion-proof.
