Description

Technical Field

[0001] The invention relates to the technical field of saturation diving pressurized chambers, in particular to a harmful gas detection and cleaning system. Background Art

[0002] In saturation diving, divers stay in a high-pressure environment for a long time, and the inert gas components in the breathing gas contained in various tissues in their bodies reach a completely saturated state. During the intervals between multiple dives, divers have to stay in the same high-pressure environment. The diving decompression chamber (or compression chamber) can provide them with a high-pressure working and living environment. After completing all underwater operations, decompression can be performed once.

[0003] The diving recompression chamber is an important equipment to help divers do saturation diving, and it is also an important means of treating decompression sickness.

[0004] The existing technical solution for cleaning harmful gases in diving pressure chambers is to add a CO2 absorber and activated carbon to absorb odors in the environmental control system.

[0005] However, according to the above content and the prior art, the above solution has the following disadvantages:

[0006] 1. The integration of harmful gas detection and cleaning systems is not high. The harmful gas detection data is only used as reference data for closed cabins and is not closely connected with the cleaning system;

[0007] 2. The replacement of harmful gas absorption devices in the cleaning system mainly relies on manual operation on time or on demand, and the control system has a low degree of intelligent control over the internal cleaning system;

Harmful gases contain a variety of ingredients that are harmful to the human body. It only absorbs CO2 and odors, and cannot achieve better purification of the environment in the closed cabin.

[0066] This system is connected to the environmental control system. When the temperature T is detected n When the temperature is lower than T1 or higher than T2, the corresponding equipment will be started to regulate the temperature.

[0067] If only humidity data A exists n When the temperature is less than A1, the harmful gas circulation power device and the harmful gas humidifying device are started, and the solenoid valve between the harmful gas circulation power device and the harmful gas humidifying device, and the solenoid valves on the air outlet duct and the fresh air return duct are opened, so that the air moves after being driven by the harmful gas circulation power device and re-enters the interior of the closed cabin after being humidified by the harmful gas humidifying device, until the humidity data inside the closed cabin is within the suitable humidity range of A1-A2 for the indoor environment of the closed cabin;

The harmful gas cleaning device will clean the harmful gas in the air. At this time, the humidity detection instrument in the harmful gas cleaning device detects the humidity of the air in the pipeline to determine the humidification effect.

[0074] When X n When <X0, the control system turns off the harmful gas cleaning system and then closes the solenoid valves DT1 and DT2.

[0075] When the harmful gas detection system detects the air humidity in the closed cabin A n > A2, first open the solenoid valves DT1 and DT2, start the harmful gas circulation power device, start the solenoid valve DT5, start the harmful gas drying device, and at the same time close the solenoid valve DT3, turn off the harmful gas humidification device, close the solenoid valve DT4, turn off the harmful gas removal device, and start the harmful gas drying device (according to the test result A n Adjust the corresponding power) to dehumidify the air in the closed cabin. When the harmful gas detection system detects the air humidity A in the closed cabin n When <A2, the harmful gas cleaning system is turned off, and then the solenoid valves DT1 and DT2 are closed.
