Description

Technical Field

[0001] The present application relates to the technical field of diving facilities, and in particular to a harmful gas removal device for an environmental control system of an ultra-deep saturation chamber. Background Art

[0002] Deep saturation diving involves prolonged underwater exposure to depths exceeding 120 meters (or even 300-500 meters). This type of operation requires divers to first spend an extended period in a hyperbaric chamber to acclimate to the high-pressure environment at great depths before returning to the water to conduct their work. This can last up to a month. According to diving medicine, the atmosphere within these chambers typically consists of a mixture of helium, oxygen, and small amounts of carbon dioxide, water, and nitrogen. The pressure can exceed 120 atmospheres (even reaching depths of 300-500 meters) depending on the situation. While acclimatizing and resting in the chamber, divers need to ingest oxygen and exhale carbon dioxide to maintain their health. Under high pressure, the human body is extremely sensitive to the partial pressure of carbon dioxide, which typically cannot exceed 0.5 kPa. Exceeding this threshold can threaten the health and life of those inside. Therefore, hazardous gas removal devices are required within hyperbaric chambers to remove gases such as carbon dioxide to protect the physical and mental health of those inside.

[0003] In the prior art, harmful gas removal devices used in environmental control systems for deep saturation chambers usually spray the gas first, and then input the gas into an absorption tank to use the adsorbent in the absorption tank to adsorb harmful gases such as carbon dioxide.

[0004] During use of the harmful gas removal device for the environmental control system of a deep saturation chamber in the prior art, workers are required to replace the adsorbent in the absorption tank at regular intervals and clean the residual water in the absorption tank, thereby increasing the maintenance and management work during the use of the harmful gas removal device.

[0027] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0028] The embodiment of the present application discloses a harmful gas removal device for an ultra-deep saturation chamber environmental control system. Figures 1 to 3 The harmful gas removal device for the environmental control system of an ultra-deep saturation tank can include a spray chamber 10, a connecting pipe 20, a delivery chamber 30, and a purification tank 40. The spray chamber 10 has a first air inlet pipe 11, which can be connected to the air supply mechanism in the cabin so that airflow can be input into the spray chamber 10. The spray chamber 10 also has a water supply pipe 12, which inputs pressurized water into the spray chamber 10 and sprays it onto the input airflow using a sprayer. The sprayed water can dissolve and absorb various trace harmful gases such as hydrogen sulfide and ammonia in the airflow. The spray chamber 10 is a prior art and will not be described in detail here. The output end of the spray chamber 10 is connected to the purification tank 40 via a connecting pipe 20, so that the airflow treated by spraying in the spray chamber 10 can be input into the purification tank 40 via the connecting pipe 20, and the airflow can absorb gases such as carbon dioxide using an absorbent in the purification tank 40. The delivery chamber 30 includes a base 31, an input port 32, a conveyor belt 33, and an output port 34. The input port 32 and the output port 34 are formed at the top and bottom of the base 31, respectively, and are arranged at both ends of the base 31 along the length direction of the base 31. The input port 32 can be used to place the absorbent assembly 44 into the base 31, and the output port 34 can be used to guide the absorbent assembly 44 out of the base 31. The conveyor belt 33 is embedded in the inner bottom of the base 31, and the conveying direction of the conveyor belt 33 is toward the output port 34. The output end of the delivery chamber 30 (i.e., the output port 34) is connected to the upper end of the purification tank 40, so that the absorbent assembly 44 stored and transported by the delivery chamber 30 can be introduced into the purification tank 40. The purification tank 40 includes an opening adjustment section 41, a top connecting section 42, a bottom connecting section 43, and an absorbent assembly 44. The top connecting section 42 and the bottom connecting section 43 are formed at the top and bottom of the opening adjustment section 41, respectively. Together, the opening adjustment section 41, the top connecting section 42, and the bottom connecting section 43 form a tank structure having an inner cavity and openings at both the upper and lower ends. After being discharged from the delivery chamber 30, the absorbent assembly 44 can be lowered onto the opening adjustment section 41. The middle portion of the opening adjustment section 41 has an adjustable opening. Adjusting the size of the opening on the opening adjustment section 41 allows the absorbent assembly 44 to drop through the opening and the lower opening of the purification tank 40. This allows the delivery chamber 30 to cooperate with the purification tank 40 to automatically replace the absorbent assembly 44.

[0029] See Figures 4 to 7 The opening adjustment section 41 includes a rotating adjustment disk 411, a plurality of movable cover plates 412 and an opening housing 413. The top and bottom of the opening housing 413 are respectively connected to the top connecting section 42 and the bottom connecting section 43, and the outer diameters of the three are equal. The rotating adjustment disk 411 is rotatably arranged inside the opening housing 413, and the plurality of movable cover plates 412 are placed between the rotating adjustment disk 411 and the top inner wall of the opening housing 413, and each movable cover plate 412 is movably connected to the rotating adjustment disk 411 and the opening housing 413. The deflection of the rotating adjustment disk 411 can adjust the position state of the plurality of movable cover plates 412, and the gaps formed between the plurality of movable cover plates 412 when the plurality of movable cover plates 412 move constitute the movable opening of the opening adjustment section 41.

[0030] In this embodiment, a fixed opening 4111 is formed in the middle of the rotary adjustment disk 411, extending through the disk. The diameter of the fixed opening 4111 is the maximum length or width that the movable opening of the opening adjustment section 41 can reach. A polygonal groove 4112 is formed on the outer side of the fixed opening 4111, which cooperates with the multiple movable cover plates 412. An external connection portion 4113 is formed on the outer wall of the rotary adjustment disk 411, extending out of the opening cover body 413. The external connection portion 4113 is connected to an external drive motor, allowing the rotary adjustment disk 411 to be driven to deflect clockwise or counterclockwise.

[0031] In this embodiment, the top inner wall of the open housing 413 is formed with a plurality of inclined slots 4132, each corresponding to each movable cover plate 412. The outer wall of the open housing 413 is also formed with a through slot 4133, through which the external connection portion 4113 movably passes, thereby limiting the deflection range of the external connection portion 4113. A positioning sleeve 4131 is formed at the top of the open housing 413, which cooperates with the absorbent assembly 44. After the absorbent assembly 44 is dropped, the positioning sleeve 4131 can be used to limit its lower end and prevent it from tipping over.

[0032] In this embodiment, the movable cover plate 412 is a plate-like structure formed by connecting triangular and rectangular segments. The triangular segments of the multiple movable cover plates 412 are evenly arranged radially along the fixed opening 4111 to form a circular shape that covers the fixed opening 4111. The rectangular segments of the multiple movable cover plates 412 extend above each side of the polygonal groove 4112. The top and bottom of the rectangular segments of each movable cover plate 412 are fixedly connected to an upper boss 4122 and a lower boss 4121, respectively. The upper boss 4122 extends into and slidably engages with the adjacent oblique groove 4132, while the lower boss 4121 extends into and slidably engages with the polygonal groove 4112. When the rotary adjustment disk 411 is deflected, the inner wall of the polygonal groove 4112 pushes the lower protrusion 4121, and the inclined groove 4132 guides the upper protrusion 4122, causing the movable cover 412 to first deflect and then slide along the inclined groove 4132, thereby expanding the movable opening formed by the gaps between the multiple movable cover plates 412. The movable opening is also polygonal in shape, and when the length and width of the movable opening are both greater than the outer diameter of the absorbent assembly 44, the absorbent assembly 44 can be lowered and discharged; when the length and width of the movable opening are both less than the outer diameter of the absorbent assembly 44, the airflow purified by the absorbent assembly 44 can flow through the movable opening and be transported downward.

[0033] See Figure 8 and Figure 9The absorbent assembly 44 includes an outer cover 441, an absorbent cartridge 442, a water-absorbing layer 443, and an annular bottom cover 444. The top and bottom of the inner wall of the outer cover 441 are formed with limiting flanges. During assembly, the top of the absorbent cartridge 442 and the annular bottom cover 444 can be fastened to the outer cover 441 in cooperation with the adjacent limiting flanges to complete the assembly. Multiple small holes are formed through the outer walls of the outer cover 441 and the outer walls of the absorbent cartridge 442. The absorbent cartridge 442 has an inner cavity with a circular cross-section. The lower end of the absorbent cartridge 442 and the middle portion of the annular bottom cover 444 are both formed with openings. This allows the airflow input into the purification tank 40 to flow through the outer cover 441 into the absorbent cartridge 442, then flow downward from the central cavity of the absorbent cartridge 442. The openings at the lower end of the absorbent cartridge 442 and the middle portion of the annular bottom cover 444 allow the purified airflow to be guided out of the absorbent assembly 44. The inner cavity of the absorbent cartridge 442 is filled with an adsorbent. The adsorbent may include soda lime or a mixture of various compounds selected based on the harmful gases to be removed, such as ammonia, nitrogen, methane, hydrogen sulfide, and the like. Water-absorbing layer 443 is sleeved onto the outside of absorbent cartridge 442 and inserted into the inner cavity of outer cover 441 simultaneously with the installation of absorbent cartridge 442. This allows the spraying airflow to pre-absorb moisture from water-absorbing layer 443. Water-absorbing layer 443 can be made of a highly absorbent plastic. Highly absorbent plastic is a functional polymer material containing highly absorbent groups such as hydroxyl groups and a certain degree of cross-linking. Highly absorbent plastic can absorb more than a thousand times its own weight in water, typically with a water absorption rate ranging from 100 to 1000. Furthermore, highly absorbent plastic has excellent water retention properties, meaning that absorbed water is not easily squeezed out even under pressure.

[0034] See Figure 3 The top of the top connecting section 42 is formed with a guide section 422 connected to the delivery chamber 30, and the absorbent assembly 44 can pass through the guide section 422 and fall down to the opening adjustment section 41. A second air inlet pipe 421 connected to the connecting pipe 20 is formed on the outer wall of the top connecting section 42, and is used to introduce the airflow to be purified. An air outlet pipe 431 is formed on the outer wall of the bottom connecting section 43, and the air outlet pipe 431 can be connected to an external exhaust fan so that the purified airflow can be extracted from the air outlet pipe 431. The extracted gas enters the condensation tank after being pressurized, and is cooled and dehumidified after heat exchange with the refrigerant water in the condensation tank. The dehumidified gas enters the heating tank and exchanges heat with the hot medium water, and the temperature is increased and sent into the cabin.

[0035] In this embodiment, the purification tank 40 further includes a sealing cover 45, which is disposed within the inner cavity of the top connecting section 42 and is located above the absorbent assembly 44 placed on the opening adjustment section 41. The sealing cover 45 is rotatably connected to the top connecting section 42 via a rotating shaft 451, and when the sealing cover 45 is deflected downward, a gap is formed between the sealing cover 45 and the absorbent assembly 44 placed on the opening adjustment section 41. A torsion spring 452 is also disposed on the rotating shaft 451 for adjusting the position of the sealing cover 45. The diameter of the sealing cover 45 is smaller than the inner diameter of the top connecting section 42 and larger than the inner diameter of the guide section 422. When the airflow to be purified is input, the pressure of the airflow can cause the sealing cover 45 to block the guide section 422, thereby preventing the airflow to be purified from flowing upward into the delivery chamber 30 and affecting the absorbent assembly 44 stored in the delivery chamber 30. When the absorbent assembly 44 stored in the delivery chamber 30 falls through the output port 34, it can pass through the guide section 422 and push the sealing cover 45 to deflect downward. In the process of the absorbent assembly 44 falling onto the opening adjustment section 41, the sealing cover 45 can also use the elastic deformation of the torsion spring 452 to reset to block the inner cavity of the guide section 422.

[0036] The system of the present invention may further include a control system for controlling the operation of the drive motor and conveyor belt to automatically replace the absorbent assembly. It should be understood that the control system is not particularly limited and can be implemented using existing control technologies, which will not be further described here.

[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
