Detailed implementation manners

[0017] The present invention will be further described below in conjunction with the accompanying drawings and implementation manners.

[0018] Please refer to Figure 1 — Figure 4 , wherein, Figure 1 Schematic overall structure diagram of the high-altitude tunnel temperature regulation device provided by the present invention; Figure 2 Partial top view of the structure of the high-altitude tunnel temperature regulation device provided by the present invention; Figure 3 Schematic horizontal sectional view of the high-altitude tunnel temperature regulation device provided by the present invention; Figure 4 Schematic vertical sectional view of the high-altitude tunnel temperature regulation device provided by the present invention.

[0019] In the specific implementation process, a high-altitude tunnel temperature regulation device and its usage method have a structure as shown in Figure 1 — Figure 4 , and include: a mounting shell 1, a first air inlet 2 is provided on one side of the mounting shell 1, a filtering assembly 3 is bolted to the inner side wall of the mounting shell 1, an oxygen extraction assembly 4 is bolted to one side of the filtering assembly 3, a temperature transfer assembly 5 is bolted inside the mounting shell 1, a first pipeline 6 is inserted into the oxygen extraction assembly 4, the first pipeline 6 is nested in the temperature transfer assembly 5 and passes through the outer side wall of the mounting shell 1, and a second air inlet 7 and an air outlet 8 for gas exchange inside the mounting shell 1 are further provided on the side wall of the mounting shell 1; It should be noted that the air is filtered by the filtering component 3 to filter out dust and other impurities with larger diameters in the air, so as to avoid affecting the normal use of the equipment. The air filtered by the filtering component 3 enters the oxygen extraction component 4. After the oxygen extraction component 4 extracts and compresses the air, oxygen is separated from gases such as nitrogen in the air to obtain oxygen with a higher purity. Then the oxygen enters the first pipeline 6. The temperature transfer component 5 cools the oxygen in the first pipeline 6 and makes the heat enter the temperature transfer component 5. The cooled oxygen is transmitted outside the installation shell 1 through the first pipeline 6 and then transmitted to the construction site or residence of the tunnel construction workers through the pipeline, providing sufficient oxygen for the construction workers and avoiding the thin oxygen caused by the high altitude area, which affects the life of the construction workers.

[0020] The temperature transfer component 5 includes an evaporator 501. The first pipeline 6 penetrates into the evaporator 501 and passes through the side wall of the evaporator 501. The other end of the evaporator 501 is bolt-connected to a first compressor 502 through a pipeline. One end of the first compressor 502 is bolt-connected to an expansion valve 503 through a pipeline. One end of the expansion valve 503 is bolt-connected to a condenser 504 through a pipeline. One end of the condenser 504 is connected to the evaporator 501 through a pipeline, and the condenser 504 is facing the air outlet 8. A cooling fan 505 facing the condenser 504 is detachably connected inside the installation shell 1. It should be noted that the evaporator 501 is filled with a condensate. The condensate uses the heat transfer working medium of an air source heat pump. The boiling point of this working medium under normal pressure is -40 °C, and the freezing point is below -100 °C. This substance is liquid when cold but is easily evaporated into gas, and vice versa. It can well absorb the heat in the oxygen. During the working process, the condensate in the evaporator 501 vaporizes after absorbing the heat of the oxygen. The vaporized working medium is compressed by the first compressor 502 to make the working medium become a gas with a higher pressure and temperature. This gas then passes through the expansion valve 503 to control the flow rate and flow of the gas. After the gas reaches the condenser 504, its temperature drops under the action of the cooling fan 505, and the heat is absorbed by the air inside the installation shell 1. The air inside the installation shell 1 is then sent out through the air outlet 8, so as to increase the external temperature. The cooled condensate gas will be transmitted back to the evaporator 501 through the pipeline, thus forming a cycle.

[0021] The oxygen extraction component 4 includes a second compressor 401. A suction pump is provided inside the second compressor 401. A second pipeline 402 penetrates through the second compressor 401. The second pipeline 402 passes through the outer side wall of the installation shell 1. The side wall of the second compressor 401 is detachably connected to the filtering component 3. The other side of the second compressor 401 is detachably connected to a selective semi-permeable plate 403. A plurality of adsorption towers 404 are provided on the other side of the selective semi-permeable plate 403. Molecular sieves are provided in each of the plurality of adsorption towers 404. It should be noted that the selective semi-permeable plate 403 is provided with multiple layers of selective semi-permeable membranes. The pore diameters of the selective semi-permeable membranes and the molecular sieve are both less than 0.364 nm and greater than 0.346 nm. Since the kinetic diameter of nitrogen molecules is 0.364 nm and the kinetic diameter of oxygen molecules is 0.346 nm, the selective semi-permeable plate 403 and the molecular sieve separate oxygen and nitrogen. Since the kinetic diameter of oxygen molecules is less than the pore diameter of the molecular sieve, relatively pure oxygen will be formed in the upper layer of the inner cavity of the adsorption tower 404. This part of the oxygen is transmitted through pipeline 1-6 to the working environment where the personnel are relatively concentrated, thus providing sufficient oxygen for the construction workers. The gas screened by the selective semi-permeable plate 403 enters the adsorption tower 404, and then the adsorption tower 404 is pressurized to increase the pressure to 1.0 - 1.2 MPa. At this time, nitrogen molecules are adsorbed and oxygen permeates through, and then the high-concentration oxygen is transmitted out of the installation shell 1 through pipeline 1-6.

[0022] The filtering component 3 includes a filter plate 301 which is bolted to the air inlet 1 on the inner side of the installation shell 1, and an activated carbon adsorption plate 302 is bolted to the other side of the filter plate 301. It should be noted that multiple circular through holes are formed in the filter plate 301, and the diameters of the multiple through holes are all less than 5 mm, so as to preliminarily filter impurities, dust, etc. in the air and avoid affecting the normal use of the equipment.

[0023] Two pipelines 3-9 are inserted into the selective semi-permeable plate 403. Both of the two pipelines 3-9 are inserted into the compressor 2-401, and one-way valves are provided in both of the two pipelines 3-9, and the installation directions of the two one-way valves are opposite. It should be noted that one of the pipelines 3-9 is used to make the gas in the compressor 2-401 flow into the selective semi-permeable plate 403, so as to filter and screen the gas. The screened impurities will be transmitted back to the compressor 2-401 through the other pipeline 3-9 and transmitted out of the installation shell 1 through the compressor 2-401.

[0024] The usage method of the above high-altitude tunnel temperature adjustment equipment specifically includes the following steps: S1. Determine the design process, connect each component in sequence, and detect the airtightness of the equipment. S2. Start each component in sequence to extract oxygen and transmit the purified oxygen to the area where construction workers are relatively concentrated. S3. Monitor the usage situation of the equipment in real time, and adjust the oxygen output flow and the expansion valve 503 in a timely manner according to the construction workers and the construction environment. S4. Regularly detect and maintain the equipment, and periodically clean the filtering component 3 and the oxygen extraction component 4. It should be noted that each component is connected in sequence according to the order of the filter plate 301, the activated carbon adsorption plate 302, the second compressor 401, the selective semi-permeable plate 403, the adsorption tower 404, the evaporator 501, the first compressor 502, the expansion valve 503, the condenser 504, and the cooling fan 505; First, start the air extraction pump in the second compressor 401 to allow external air to enter the device through the first air inlet 2. The air passes through the filter plate 301 and the activated carbon adsorption plate 302 for preliminary filtration to prevent dust and other impurities in the air from entering the device and affecting the extraction of oxygen. Then, the selective semi-permeable plate 403 is used to preliminarily separate oxygen molecules and nitrogen molecules. The gas after preliminary separation enters multiple adsorption towers 404. By pressurizing the adsorption towers 404, the molecular sieve separates nitrogen molecules and oxygen molecules. Then, the separated high-concentration oxygen enters the evaporation tube through the first pipeline 6. At this time, the working fluid in the evaporation tube absorbs the heat of the oxygen and heats up. The cooled oxygen is discharged to the area with a dense construction workforce through the first pipeline 6. The heated working fluid is further compressed by the first compressor 502 to further increase the temperature. The flow rate of the working fluid is adjusted by the expansion valve 503 so that the working fluid cools down sufficiently in the condenser 504, and the heat of the working fluid is absorbed by the air in the inner cavity of the installation shell 1. Then, the cooling fan 505 discharges the air in the inner cavity of the installation shell 1 from the air outlet 8 to achieve the purpose of adjusting the temperature of the tunnel construction environment.
