Description

Technical Field

[0001] The present invention belongs to the technical field of mobile shelters, and particularly relates to an oxygen - making support mobile shelter and an oxygen - making method. Background Art

[0002] The existing oxygen - making support mobile shelter adopts a mobile shelter structure. The oxygen - making and auxiliary equipment are fixed in the mobile shelter through mechanical interfaces. The oxygen production and oxygen - pressurizing rate are developed or selected according to the number of equipped people, and the maximum filling pressure is mostly not less than 15 MPa.

[0003] It is mainly used for oxygen - making support in various scenarios. During the rapid march to the high - altitude area, the training personnel need to prevent acute altitude reaction and acute altitude diseases, and ensure the oxygen use at scattered points in the permanent residence. The oxygen - making support mobile shelter can provide support for preventing acute altitude reaction, oxygen therapy and health care during various tasks such as personnel training in the field and military exercises, and ensure the life and health of personnel.

[0004] The existing oxygen - making support mobile shelter is limited by the size of the mobile shelter, with small oxygen production, slow oxygen - pressurizing rate, and limited support ability. The support ability is also relatively single, and mostly can only supply oxygen by means of compressed gas cylinders. In the places where multiple people need to inhale oxygen simultaneously, such as field hospitals, multi - person meetings, and convalescence of the wounded, it cannot meet the oxygen use requirements of multiple people at the same time. When patients with ischemic and hypoxic diseases need emergency hyperbaric oxygen therapy, it cannot provide a hyperbaric oxygen - using environment. At the same time, the oxygen - making support mobile shelter is used for emergency oxygen supply support, and it is required to be used normally in various field environments, especially in areas where the power network cannot be covered. However, the common oxygen - making support mobile shelters can often only be powered by the commercial power supply and cannot be applicable to all regions, let alone the external power supply function. Moreover, for common oxygen - making mobile shelters, their consideration of informatization ability is not comprehensive enough, and they cannot achieve functions such as full - process controllability, displayability, and operability of key equipment, which brings cumbersome work content and high work intensity. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an information - based oxygen - making mobile shelter that can supply oxygen to multiple people simultaneously in a high - pressure environment.

[0006] To solve the above - mentioned technical problem, the specific technical solution of the present invention is as follows:

[0007] An oxygen - making support mobile shelter includes a filling equipment room 100, an expansion room 200, a main equipment room 300, a generator room 400, and a container bracket 500;

[0008] The generator room 400 is used to provide power input for the equipment in the filling equipment room 100, the expansion room 200, and the main equipment room 300, including two power supply modes: commercial power and diesel power generation; after receiving the electric energy from the generator room 400, the main equipment room 300 starts the full set of oxygen production process and sends the produced oxygen to the filling equipment room 100 for filling; during the oxygen production process, the display and control terminal in the expansion room 200 is used to monitor the oxygen production process, observe the working pressure and status of each component in the gas path to see if they are normal, and perform the start and stop of the equipment and the adjustment of the threshold pressure of each component; the filling equipment room 100, the expansion room 200, the main equipment room 300, and the generator room 400 together constitute the main structure of the shelter, and are fixed on the container bracket 500 through corner piece locks.

[0009] Further, 2L oxygen cylinders 101, 40L oxygen cylinders 103, and 40L oxygen cylinder transfer carts 102 are hung on the wall panels of the filling equipment room 100.

[0010] Further, the display and control terminal 201 and the oxygen inhalation interface 203 beside the cabin in the expansion room 200 are integrated in an in - recessed wall box, and the wall box is hung on the wall panel of the expansion room 200.

[0011] Further, the main equipment room 300 is the core of the entire oxygen production support shelter, and an oxygen compressor 301, an oxygen buffer tank 302, an oxygen production host 303, an air compression and cold drying integrated machine A 304, an air compression and cold drying integrated machine B 305, and an air buffer tank 306 are fixed on its wall panel or bottom.

[0012] Further, a power distribution cabinet 307 and a nitrogen discharge tower 308 are also arranged inside the main equipment room 300. The exhaust pipe connected to the nitrogen discharge tower 308 is fixed to the cabin wall through a buckle, and a louver is arranged opposite the nitrogen discharge tower.

[0013] Further, a generator set 402 is built in the generator room 400, and the generator set 402 is fixed to the bottom plate through multiple long buried irons inside the bottom plate; a Helmholtz muffler 401 is arranged on the generator exhaust pipe 403, and the generator exhaust pipe 403 is fixed to the cabin wall through a buckle.

[0014] Further, 8 oxygen inhalation terminals are arranged in the expansion room.

[0015] The present invention also provides an oxygen production method based on the above - mentioned oxygen production support shelter, which specifically includes the following steps:

[0016] S1. The generator set starts or commercial power is connected to provide energy input for each device of the oxygen production support shelter;

[0017] S2. First, the air in the mobile cabin is pressurized by the compression modules of two air compression and cold drying integrated machines, and then the compressed air is transported through pipelines to the cold drying module of the air compression and cold drying integrated machine for cold drying treatment;

[0018] S3. The cold-dried compressed air is transmitted through pipelines to the air buffer tank, and after being filtered and purified by the filter, clean air meeting the quality requirements is obtained;

[0019] S4. The clean air is input into the oxygen generation host, and oxygen is directly produced from the compressed air through the principle of pressure swing adsorption and pressure reduction desorption. After being filtered by the filtration system, the finished oxygen meeting the design requirements is output and stored in the oxygen buffer tank;

[0020] S5. After the finished oxygen is compressed by the oxygen compressor, the pressure is increased to 15 MPa, and the compressed oxygen enters the gas cylinder group through pipelines for storage;

[0021] S6. The oxygen in the gas cylinder group can be used to fill oxygen cylinders through filling equipment, or can be decompressed and used for on-site oxygen inhalation through professional equipment.

[0022] Furthermore, the adsorbent of the oxygen generation host adopts medical-grade small particle sodium-lithium mixed molecular sieve.

[0023] Furthermore, the steps of producing oxygen in S4 are specifically as follows:

[0024] Step 4.1. The oxygen generation process adopts the PSA oxygen generation process. When air enters the adsorption tower, under the action of pressure, nitrogen and carbon dioxide are quickly adsorbed, and oxygen molecules form enriched oxygen near the gas outlet in the tower;

[0025] Step 4.2. When the adsorption process proceeds to the point where the adsorption ratio of oxygen to nitrogen is the smallest, open the gas outlet valve and output the finished oxygen to the oxygen buffer tank;

[0026] Step 4.3. After the exhaust process is completed, there is still a certain pressure and a certain purity of oxygen mixture gas in the tower. Discharge it into another adsorption tower through the pressure equalizing valve to be adsorbed again together with the incoming air next. This process ends when the pressures of the two towers are equal;

[0027] Step 4.4. After the pressure equalization is completed, release the gas adsorbed by the molecular sieve in the tower to prepare for the next adsorption. Open the exhaust valve to make the pressure in the tower return to the initial state, and use the regeneration gas to purge the molecular sieve to discharge the gas adsorbed by the molecular sieve, so that the molecular sieve can regain the ability to adsorb new air; The two adsorption towers work alternately.

[0028] The present invention has the following advantages: Compared with traditional oxygen-making shelters, this new type of flip-type expandable oxygen-making shelter has a more compact structure and an optimized oxygen-making method and process, making it more suitable for use, transportation, and installation in various scenarios, avoiding the problems of occupying a large space, causing difficulties in transportation, and affecting the vehicle stability. Secondly, using the expansion cabin as the form of the oxygen inhalation site beside the cabin and the terminal control site is more convenient for personnel to use immediately and monitor and control the oxygen-making equipment, effectively increasing the actual usable area of the shelter and the functions of the oxygen-making shelter; at the same time, a containerized bracket is equipped for the new type of oxygen-making shelter, increasing its transportation methods, thus increasing the deployable locations and improving the utilization rate. By standardizing the unfolding and retracting processes, the new type of oxygen-making shelter can be unfolded and retracted relatively easily, improving the deployment and withdrawal efficiency and safety.

[0029] The oxygen-making method using the form of two adsorption towers works alternately, improving the oxygen-making efficiency and oxygen-making purity. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0043] To better understand the purpose, structure and function of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] As Figure 1 shown, this embodiment first provides an expandable oxygen generation support shelter, which mainly includes five parts: a filling equipment room 100, an expansion room 200, a main equipment room 300, a generator room 400, and a container bracket 500. The generator room 400 mainly provides power input for the equipment in the filling equipment room 100, the expansion room 200, and the main equipment room 300, and there are two power supply modes: mains power and diesel power generation, which can be selected according to whether there is mains power input at the site. After receiving the electric energy from the generator room 400, the main equipment room 300 starts the full set of oxygen generation process and sends the generated oxygen to the filling equipment room 100 for filling. During the oxygen generation process, the display and control terminal in the expansion room 200 is responsible for monitoring the entire process, mainly observing the working pressure and status of each component in the gas path to see if they are normal, and performing the start and stop of the equipment and the adjustment of the threshold pressure of each component. The filling equipment room 100, the expansion room 200, the main equipment room 300, and the generator room 400 together form the main structure of the shelter, which is fixed on the container bracket 500 through angle piece locks, providing a more convenient means of transporting the oxygen generation support shelter.

[0045] The filling equipment room mainly realizes the filling and storage of oxygen with a pressure of 15 MPa after being compressed by the oxygen compressor 301; the expansion room mainly realizes oxygen inhalation beside the cabin and provides an operation display and control terminal area; the main equipment room mainly realizes the preparation of high-concentration oxygen from the external air through the process of the air compression and cold drying integrated machine 304, the air buffer tank 306, the oxygen generation host 303, the oxygen buffer tank 302, and the oxygen compressor 301. At the same time, it can also control the electrical system of the whole cabin and provide an external power supply interface; the generator room mainly realizes the power generation function, provides a three-phase four-wire 380V power supply, and after being allocated by the power distribution system, it is output externally through the external power transmission interface; the container bracket mainly realizes the fixation of the oxygen generation support square cabin through the corner fitting lock, and at the same time provides an interface for the CBX type lorry crane, facilitating the transportation and deployment of the oxygen generation support square cabin. These 5 parts constitute the new type of expandable oxygen generation support square cabin.

[0046] On the wall panel of the filling equipment room 100, 2L oxygen cylinders 101, 40L oxygen cylinders 103, and 40L oxygen cylinder transporters 102 are hung. The 2L oxygen cylinder mainly ensures the oxygen inhalation carried by a single person; the 40L oxygen cylinder mainly ensures the oxygen demand of barracks, places, etc. Due to its large weight, it is necessary to connect the support to the embedded iron in the square cabin for bolt connection and fixation.

[0047] The display and control terminal 201 and the oxygen inhalation interface 203 beside the cabin in the expansion room 200 are integrated in the concave wall box, and then the wall box is connected to the wall panel of the expansion room 200. The display and control terminal mainly focuses on functions such as the status monitoring, control management, information upload, alarm, and command communication of each device. Through the open architecture of dual CAN buses and distributed acquisition and control, the information data of the oxygen generation integrated controller, generator set equipment, intelligent power distribution device, and ultra-short wave radio are centrally displayed and controlled. The comprehensive display and control terminal can receive the information of the gas storage volume of the oxygen generation system, sensor data information in real time, and has functions such as comprehensive situation processing, power distribution control, and information acquisition of the whole cabin. It realizes the functions of information display, integrated management, command, and information interconnection of the whole cabin. There are 8 oxygen inhalation terminals set in the expansion room, and direct oxygen inhalation can be carried out in the cabin without starting the oxygen generation device when the square cabin is docked.

[0048] The main equipment room 300 is the core of the entire oxygen production support shelter. Among them, the oxygen compressor 301, oxygen buffer tank 302, oxygen production main unit 303, air compression and cold drying integrated machine A 304, air compression and cold drying integrated machine B 305, and air buffer tank 306 are all fixed by embedding iron pieces pre-buried in the bottom or top wall panels of the main equipment room 300 to fix the equipment. The power distribution cabinet 307 is directly fixed to the wall panel by bolts. The exhaust pipe connected to the nitrogen discharge tower 308 is fixed to the cabin wall by a buckle. There is a louver opposite the nitrogen discharge tower to facilitate the discharge of nitrogen. This is the core of the entire oxygen production support shelter. Using the PSA oxygen production principle and a reasonable oxygen production process, it ensures the oxygen production and supply in various scenarios and meets various oxygen usage requirements. Various heavy equipment is bolted and fixed to the shelter floor with a reasonable arrangement of embedded iron pieces. At the same time, the strength and stiffness of the shelter structure under random vibration in the road spectrum specified by GJB are verified, meeting the usage requirements.

[0049] The generator set 402 in the generator room 400 has a large mass and is fixed to the floor through multiple long embedded iron pieces inside the floor to ensure the reliability of the structure. At the same time, the power of the generator is large, and a loud howl will be generated during exhaust when it works. The Helmholtz muffler 401 is located on the generator exhaust pipe 403 to prevent the howl from being generated when the generator exhausts, reducing the hearing impact on the oxygen-absorbing personnel beside the shelter and the shelter operators. The generator exhaust pipe 403 is fixed to the cabin wall by a buckle and is connected to the cabin wall at the other end.

[0050] The container support 500 is fixed to the shelter corner fittings through corner fitting locks, thereby fixing the oxygen production support shelter on the container support, facilitating the transportation and layout of the oxygen production support shelter. The container support provides a new means of transportation for the shelter, that is, a CBX-type container vehicle with a pulling arm can be used to transport the new oxygen production support shelter to the designated location. At the same time, a common equipment toolbox can be selected near the front A frame of the container support to store the commonly used oxygen-absorbing consumables, facilitating the use of this invention.

[0051] The operation process of this oxygen production support shelter is as follows:

[0052] When the new oxygen production support shelter needs to perform operations, first, the new oxygen production support shelter is transported to the designated location by a CBX-type container vehicle with a pulling arm.

[0053] When receiving the operation instruction, in the first step, the new oxygen production support shelter is unloaded from the pulling arm vehicle. If the shelter needs to operate alone (without the container support), the corner fitting locks between the container support and the shelter structure need to be opened, and the shelter is transported from the container support to a flat ground by a forklift.

[0054] In the second step, each wall panel in the expansion area is turned out and opened and supported. After expansion, the structure is as Figure 5As shown, the expansion area mainly realizes the functions of control and oxygen inhalation beside the cabin.

[0055] In the third step, select one of the power supply methods of mains power and diesel generator power according to needs. If mains power supply is required, connect to the AC 380V / 100kW mains interface; if generator power generation is required, turn on the 100kW high-altitude diesel generator set to supply power to the equipment in the cabin.

[0056] In the fourth step, turn on the air compression and cold drying integrated machine, oxygen generation host, and oxygen compressor in the main equipment room in sequence at the control end of the expansion area, and observe whether the operating temperatures and pressures of each device and the gas storage tank are normal through the terminal.

[0057] In the fifth step, for external support, the new oxygen generation support shelter has four external support modes. Fill the oxygen cylinders and directly provide oxygen cylinders for the camp tents set up at the site; for oxygen inhalation beside, an oxygen inhalation port is set on the side of the high-pressure expansion shelter, and personnel can directly inhale oxygen beside; set up an oxygen inhalation pipeline, and the oxygen pipeline can be directly connected to the marquee, tent, etc., and the prepared oxygen is connected to the user's oxygen inhalation through the pipeline; the oxygen generation support shelter stores oxygen cylinders on board to meet the temporary emergency oxygen demand.

[0058] This embodiment also provides an oxygen generation method based on the above-mentioned oxygen generation support shelter, including the following steps:

[0059] Step 1: Start the generator set or connect to the mains power to provide energy input for each device of the oxygen generation support shelter;

[0060] Step 2: First, the air in the shelter is pressurized by the compression module of the air compression and cold drying integrated machine, and then the compressed air is transported through the pipeline to the cold drying module for cold drying treatment;

[0061] Step 3: The cold-dried compressed air is transported through the pipeline to the air buffer tank. After being filtered and purified by the filter, clean air meeting the quality requirements is obtained (meanwhile, the air buffer tank is equipped with a safety valve, a pressure gauge, and a drain valve to respectively realize the safe escape of gas with excessive pressure, pressure monitoring, and the discharge of condensed water);

[0062] Step 4: The clean air is input into the oxygen generator. The adsorbent of the oxygen generator adopts medical-grade small-particle sodium-lithium mixed molecular sieve. Utilizing the difference in the adsorption amounts of oxygen and nitrogen in the compressed air on the surface of the molecular sieve, oxygen is directly produced from the compressed air through the principle of pressurized adsorption and depressurized desorption. After being filtered by the filter system, the finished oxygen meeting the design requirements is output and stored in the oxygen buffer tank.

[0063] Step 4.1: The oxygen generation process adopts the PSA oxygen generation process. When air enters the adsorption tower, under the action of pressure, nitrogen and carbon dioxide are quickly adsorbed, and oxygen molecules form enriched oxygen near the outlet of the tower.

[0064] Step 4.2: When the adsorption ratio of oxygen to nitrogen during the adsorption process reaches the minimum, open the outlet valve to output the finished oxygen to the oxygen buffer tank. The oxygen buffer tank is equipped with a safety valve, a pressure gauge, and a series of detection devices to respectively achieve the safe escape of gas with excessive pressure, pressure monitoring, and quality monitoring of the finished oxygen.

[0065] Step 4.3: After the exhaust process is completed, there is still a certain pressure and a certain purity of oxygen mixture gas in the tower. Discharge it into another adsorption tower through the pressure equalization valve and perform re-adsorption together with the incoming air in the next step. This process ends when the pressures of the two towers are equal.

[0066] Step 4.4: After the pressure equalization is completed, release the gas adsorbed by the molecular sieve in the tower to prepare for the next adsorption. The program automatically opens the exhaust valve to return the pressure in the tower to the initial state. Use the regeneration gas to purge the molecular sieve to discharge the gas adsorbed by the molecular sieve, so that the molecular sieve can regain the ability to adsorb new air. The two adsorption towers work alternately to produce oxygen with a purity of 93%.

[0067] Step Five: The finished oxygen is compressed by an oxygen compressor to increase the pressure to 15 MPa, and the compressed oxygen enters the gas cylinder group through a pipeline for storage.

[0068] Step Six: The oxygen in the gas cylinder group can be used to fill oxygen cylinders through filling equipment, or can be decompressed and used for in-cabin oxygen inhalation through professional equipment.

[0069] Generally speaking, this embodiment provides a standard CAF60 mobile cabin with functions of oxygen filtration, preparation, compression, and filling, which can supply oxygen to personnel in external places. The purity of the prepared oxygen meets the requirement of not less than 93%, and the oxygen storage capacity is not less than 50 cubic meters. In addition to this oxygen generation function, a micro-pressure oxygen cabin is provided inside the cabin for the recuperation of the wounded, simple treatment of the wounded, and a place for the temporary recovery of oxygen-deficient personnel. In terms of energy, dual power supplies of mains electricity and a generator set are provided. The diesel generator set equipped with the oxygen generation equipment not only needs to provide power supply guarantee for its own equipment, but also is required to be able to serve as an emergency power station to provide power supply at various voltages for other electrical equipment. In terms of transportation, it can meet the transportation conditions of CAF60 mobile cabin transport vehicles and CBX01 and other hooklift trucks. Finally, in terms of control, an integrated display and control technology is provided, which can monitor and alarm the status of the oxygen generation equipment and the oxygen generation environment in real time.

[0070] Specifically, by designing an oxygen generation form with alternating adsorption in a double adsorption tower and cooperating with a program-controlled gas path valve, the property of continuously generating oxygen supply with a purity of 93% can be achieved; by adopting the structural form of a flip-type extended mobile cabin, the available volume of the mobile cabin is expanded, and at the same time, high-pressure oxygen is introduced into the extended area of the mobile cabin through pipelines for diffusion oxygen supply after pressure distribution; by estimating the overall power consumption of the oxygen generation support mobile cabin, a high-altitude diesel generator set is equipped to meet the normal use and external power supply of the oxygen generation support mobile cabin in areas without power grid coverage, and a compartment separation design is adopted to keep a safe distance from the oxygen generation and supply system, improving the safety of the design; through universal corner fittings, the mobile cabin can be transported by a mobile cabin transport vehicle, and through the mobile cabin skid structure, it can be transported by a hooklift truck of models such as CBX01; through an open framework with a dual CAN bus and distributed acquisition control, the information data of the oxygen generation integrated controller, generator set equipment, intelligent power distribution device, and ultra-short wave radio are centrally displayed and controlled. Such an oxygen generation support mobile cabin has a wider application scenario and can improve the use efficiency and safety of the oxygen generation support mobile cabin.

[0071] The advantages of the present invention are as follows. First, compared with the traditional oxygen generation mobile cabin, the new flip-type extended oxygen generation mobile cabin has a more compact structure and an optimized oxygen generation method and process, which makes it more suitable for use, transportation, and installation in various scenarios, avoiding the problems of occupying a large space, causing difficulties in transportation, and affecting the vehicle stability. Second, adopting the extended cabin as the form of the side oxygen inhalation and terminal control site is more convenient for personnel's immediate use and the monitoring and control of oxygen generation equipment, effectively increasing the actual usable area of the mobile cabin and the functions of the oxygen generation mobile cabin; at the same time, a container bracket is equipped for the new oxygen generation mobile cabin, increasing its transportation methods, thereby increasing the deployable locations and improving the utilization rate. By standardizing the deployment and retraction process, the deployment and retraction of the new oxygen generation mobile cabin can be achieved more easily, improving the deployment and retraction efficiency and safety.

[0072] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, for those skilled in the art, without departing from the principle of the present invention, several deformations and improvements can still be made, and these should also be regarded as belonging to the protection scope of the present invention.

Open the exhaust valve to return the pressure in the tower to the initial state, and use the regeneration gas to purge the molecular sieve to discharge the gas adsorbed by the molecular sieve, so that the molecular sieve can regain the ability to adsorb new air; The two adsorption towers work alternately.
