Technical Field

[0001] The present invention relates to the technical field of underground construction air control systems, and in particular to an air purification system for the construction environment of underground construction equipment. Background Art

[0002] Underground engineering refers to civil engineering projects built deep below the ground for the development of underground space resources. Its work sites include underground houses and underground structures, subways, highway tunnels, underwater tunnels, underground common trenches and underpasses, etc. During the operation of underground engineering projects, the closed underground work sites need to be ventilated to avoid the accumulation of harmful gases and oxygen consumption, which would endanger construction safety.

[0003] At present, the air used in underground construction is directly delivered to the underground workplace in the form of inflation or exhaust by positive pressure fans, negative pressure fans and jet fans, so as to ventilate the underground workplace. However, according to the difference of the underground workplace, the air at the air inlet needs to be purified. For example, when the underground workplace is undergoing preliminary blasting and excavation, the air in the workplace is full of dust. At this time, the air entering the air inlet needs to be purified and humidified so that the water mist can quickly absorb the dust and purify the underground workplace.

[0004] When carrying out later decoration work and spraying work in underground workplaces, the air temperature and humidity in the workplace are relatively high. At this time, it is necessary to purify, cool and dehumidify the air entering the air inlet, replace the dirty and high-temperature gas in the workplace, and blow it to the air outlet.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Example, see Figures 1 to 7 , an air purification system for an underground construction equipment construction environment, comprising an air purification pipe 1 fixedly installed at an air inlet of the underground construction environment, the air purification pipe 1 conveys air from the external environment to the underground construction environment through a fan, and a temperature control component and a humidity control component are arranged in the air purification pipe 1, respectively used to control the temperature and humidity of the air entering the underground construction environment from the air inlet;

[0035] It should be noted that the fan mentioned above can be an existing positive pressure fan or a negative pressure fan. The only difference is that the positive pressure fan is arranged on the air inlet side of the air purification pipe 1, and the negative pressure fan is arranged on the air outlet side of the air purification pipe 1. When the fan is started, the air in the external environment can be transported to the underground construction environment through the temperature control component and the humidity control component. The air transportation process is an existing technology and will not be repeated in the following.

[0036] like Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, the temperature control component includes a heating tube 2 and a cooling tube 3 arranged at the air inlet of the air purification tube 1. The heating component is fixedly installed in the heating tube 2. The heating component consists of a heating rod 21 and a heating mounting bracket 22. The heating rod 21 is heated by an electric heating rod. There are multiple cooling tubes 3, and the multiple cooling tubes 3 are rotationally symmetrical and distributed on the outside of the axis of the heating tube 2. An insulation cavity adapted to the heating tube 2 and the cooling tube 3 is arranged in the air purification tube 1. The insulation cavity is made of insulation material, and the air pressure on the air inlet side of the insulation cavity is greater than that on the air outlet side. The cooling tube 3 is made of a throttling expansion capillary tube. The high pressure of air on the air inlet side of the insulation cavity passes through the throttling expansion capillary tube to form air throttling expansion and cooling conditions, so that the air can be cooled when passing through the cooling tube 3.

[0037] It should be noted that: when the air needs to be cooled through the air purification tube 1, the ventilation control component controls the air to pass through the cooling tube 3. Through the air throttling expansion cooling principle, when the high-pressure air passes through the cooling tube 3 of the throttling expansion capillary copper tube, the temperature on the air outlet side of the temperature control component is reduced, thereby achieving the purpose of cooling the air;

[0038] Based on the above, when the air needs to be heated up through the air purification tube 1, the ventilation control component controls the air to pass through the heating tube 2, and turns on the electric heating rod so that the heating rod 21 heats the air, and the temperature on the air outlet side of the temperature control component is heated up, thereby achieving the purpose of heating the air.

[0039] Furthermore, a vent 23 is opened on the inner wall of the heating pipe 2, and a closing plug 24 is slidably connected to the inner wall of the heating pipe 2. A compression spring 25 is arranged on the closing plug 24 near the air outlet side of the heating pipe 2. When there is no airflow passing through the heating pipe 2, the closing plug 24 closes the vent 23 through the compression spring 25.

[0040] It should be noted that: when the air is only transported to the air outlet side of the temperature control component through the heating tube 2, the air squeezes the closing plug 24, and when its air pressure is greater than the elastic force of the compression spring 25, the vent 23 is connected to the heating tube 2, and when the air pressure in the heating tube 2 is lower than the elastic force of the compression spring 25, the vent 23 is closed, so that the air entering the heating tube 2 undergoes an intermittent compression process, thereby extending the contact time between the air and the heating rod 21 and improving the air heating capacity.

[0041] like Figure 2 , Figure 4 and Figure 5As shown, the humidity control component includes a humidifying tube 4 and a dehumidifying tube 5 arranged on the air outlet side of the temperature control component. The dehumidifying tube 5 is located above the humidifying tube 4 and is separated by a ventilation partition 11. A dehumidifying purification net 51 is arranged in the dehumidifying tube 5. The dehumidifying purification net 51 is made of heat-conducting metal. A dehumidifying collection box 52 located at the bottom of the dehumidifying purification net 51 is arranged in the dehumidifying tube 5. The dehumidifying collection box 52 is connected to the humidifying tube 4;

[0042] A humidifying vortex tube 41 is rotatably arranged in the humidifying tube 4, and an ultrasonic atomizing tube 42 is connected to the rotation center of the humidifying vortex tube 41. Liquid contained in the ultrasonic atomizing tube 42 forms atomized water droplets through an ultrasonic atomizer. The outer sides of multiple humidifying vortex tubes 41 are interconnected through a humidifying purification net 411, and the humidifying purification net 411 is vortex-arranged, and the length is adapted to the diameter of the humidifying tube 4.

[0043] It should be noted that: when the air needs to be humidified, the air regulated by the temperature control component is passed through the humidification tube 4 only through the ventilation control component, and when passing through the humidification vortex tube 41, the air is preliminarily humidified through the humidification purification net 411 connected to the outside thereof, and the water contained in the ultrasonic atomization tube 42 is atomized by the ultrasonic atomizer, and the air after passing through the spherical filter 12 can be further humidified, thereby improving the air humidification capacity;

[0044] Based on the above, when the air needs to be dehumidified, the air regulated by the temperature control component is passed through the dehumidification pipe 5 only through the ventilation control component, and when passing through the dehumidification pipe 5, the air is cooled by the dehumidification purification net 51 made of heat-conducting metal, so that the air can capture gaseous water when passing through, thereby achieving the purpose of air dehumidification.

[0045] A further benefit of adopting the above method is that when the air passes through the humidification and purification net 411, it can drive the humidification vortex tube 41 to rotate, and the water contained in the humidification tube 4 is reversely transported to the ultrasonic atomization tube 42, so that the water captured by the dehumidification and purification net 51 can be recycled, and when the humidification tube 4 rotates, the humidification and purification net 411 can be submerged below the water surface, thereby increasing the moisture contained in the humidification and purification net 411, so that when the air passes through the humidification tube 4, the water-rich humidification net 411 can improve the initial humidification capacity of the air.

[0046] Furthermore, the cross section of the humidifying vortex tube 41 is vortex-shaped, and a plurality of humidifying vortex tubes 41 are provided. The rotational power of the plurality of humidifying vortex tubes 41 is provided by the conveying airflow in the air purification tube 1, and the rotation direction of the humidifying vortex tube 41 is opposite to the vortex direction.

[0047] It should be noted that a one-way valve is provided on the inner wall of the ultrasonic atomization tube 42 in the water storage chamber, and when the water collected by the humidification vortex tube 41 is less, the liquid in the water storage chamber is replenished;

[0048] Based on the above, when the air passes through the humidification tube 4, the air is intercepted by the humidification purification net 411, so that the passing air provides power for the rotation of the humidification tube 4, thereby the liquid contained in the humidification tube 4 is transported to the ultrasonic atomization tube 42 through the humidification vortex tube 41 rotating in the reverse vortex direction, providing humidification liquid for the atomization liquid storage chamber of the ultrasonic atomization tube 42.

[0049] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the air purification tube 1 is provided with a ventilation control component on the air outlet side of the heating tube 2 and the cooling tube 3, and the ventilation control component includes a ventilation control disk 6 rotatably connected to the inner wall of the air purification tube 1, and the ventilation control disk 6 is composed of a temperature control ventilation disk 61 and a humidity control ventilation disk 62, and the rotation of the temperature control ventilation disk 61 and the humidity control ventilation disk 62 is controlled by a stepper motor 64, and a humidity matching disk 63 is fixed to the humidity control ventilation disk 62 near the side of the ventilation control disk 6, and a dehumidification matching net 631 is provided on the humidity matching disk 63, and a low-temperature ventilation hole 611 adapted to the orientation of the cooling tube 3 is opened in the temperature control ventilation disk 61, and the low-temperature ventilation hole 611 and the vent 23 are staggered, and the dehumidification matching net 631 covers the low-temperature ventilation hole 611 and the air outlet side of the vent 23.

[0050] It should be noted that: when the air needs to be cooled down after passing through the temperature control component, the stepper motor 64 located on the temperature control ventilation disk 61 is started, so that the low-temperature ventilation hole 611 is connected with the cooling pipe 3, and the heating pipe 2 is closed, so that the air can only be transported to the humidity control component through the cooling pipe 3;

[0051] Similarly, when the air needs to be aligned and heated when passing through the temperature control component, the temperature control ventilation disk 61 is controlled to rotate so that the low-temperature ventilation hole 611 is misaligned with the cooling tube 3, and the blockage of the heating tube 2 is released, so that the air can only be transported to the humidity control component through the heating tube 2, thereby completing the ventilation control operation during the air temperature control process.

[0052] Based on the above, when the air needs to be aligned and humidified after passing through the humidity control component, the stepper motor 64 located on the humidity control ventilation disk 62 is started, so that the through hole set on the humidity matching disk 63 is aligned with the pipe opening of the humidification tube 4, and the ventilation channel of the dehumidification tube 5 is closed, so that the air after temperature control only passes through the humidification tube 4, and is humidified by the humidification purification net 411 and the ultrasonic atomization tube 42;

[0053] Similarly, when the air needs to be dehumidified after passing through the humidity control component, the humidity control ventilation disk 62 is controlled to rotate so that the through hole set on the humidity matching disk 63 is aligned with the pipe mouth of the dehumidification tube 5, so that the air after temperature control only passes through the dehumidification tube 5, and the moisture contained in the air is captured by the dehumidification purification net 51 to achieve the purpose of dehumidification, thereby completing the ventilation control operation in the process of air humidity control.

[0054] The further advantage of adopting the above method is that the number of low-temperature vents 611 and vents 23 is set to be a multiple of three and an odd number, and the number of the dehumidification matching net 631, the low-temperature vents 611 and the vents 23 is the same, and when the humidity control ventilation disk 62 rotates 180 degrees, the connection state of the dehumidification matching net 631 and the low-temperature vents 611 or the vents 23 can be freely switched;

[0055] Based on the above, when the cooled air needs to be dehumidified, the stepper motor 64 arranged on the top of the humidity control ventilation disk 62 drives the humidity control ventilation disk 62 to rotate, and after the rotation, the through hole in the humidity control ventilation disk 62 is connected with the dehumidification pipe 5, and the dehumidification matching net 631 rotates to align with the area where the cooling pipe 3 is located, that is, to align with the area where the low-temperature ventilation hole 611 is located, so that the dehumidification matching net 631 can contact with the air after passing through the cooling pipe 3, and the dehumidification matching net 631 arranged by the heat conductive material can preliminarily capture the moisture in the air;

[0056] When the cooled air needs to be humidified, the humidity control ventilation disk 62 is rotated 180 degrees so that the dehumidification matching net 631 is not aligned with the area where the cooling pipe 3 is located, so that the air after passing through the cooling pipe 3 directly enters the humidification pipe 4 for humidification without blocking the passing air.

[0057] Further based on the above, similarly, when it is necessary to dehumidify the heated air, the humidity regulating ventilation disk 62 is rotated so that the dehumidification matching net 631 is aligned with the vent 23, so that it can come into contact with the air after passing through the heating tube 2, and preliminarily capture the moisture in the air. When the cooled air needs to be humidified, the humidity regulating ventilation disk 62 is rotated one hundred and eighty degrees so that the dehumidification matching net 631 is not aligned with the vent 23, so that the air after passing through the heating tube 2 directly enters the humidification tube 4 for humidification, and the passing air is not blocked, thereby the dehumidification matching net 631 cooperates with the dehumidification purification net 51 to capture the moisture of the passing air twice, thereby achieving the effect of improving the air dehumidification capacity.

[0058] Furthermore, the closing plug 24 is connected to a ventilation control column 26 that slides with the inner wall of the air purification tube 1 through a compression spring 25. A blocking bracket 612 is provided at the rotation center of the temperature-controlled ventilation disk 61. The blocking bracket 612 is slidably connected to the ventilation control column 26 through a limiting slider 613 to control the position of the ventilation control column 26.

[0059] It should be noted that: when the air passes through the temperature control assembly and needs to be cooled, the low-temperature vent 611 is aligned with the area where the cooling pipe 3 is located, and the ventilation control column 26 slides inside the ventilation control column 26, squeezing the ventilation control column 26 to close the vent 23;

[0060] When the air passes through the temperature control component and needs to be heated, the stepper motor 64 located on the temperature control ventilation disk 61 drives the temperature control ventilation disk 61 to rotate, closes the area where the cooling pipe 3 is located, and allows the ventilation control column 26 to slide reversely inside the ventilation control column 26, so that the limited position of the ventilation control column 26 moves toward the air outlet side of the temperature control component, releases the closed state of the vent 23, and allows the air to pass through the heating pipe 2. The heated air can be transported to the humidity control component.

[0061] like Figure 2 and Figure 5 As shown, the air purification component includes a spherical filter 12 and a dust filter tube 421. The spherical filter 12 is arranged on the air outlet side of the humidification tube 4 and the dehumidification tube 5 to filter and purify the air passing through the humidification tube 4 and the dehumidification tube 5. One end of the dust filter tube 421 is connected to the ultrasonic atomization tube 42 to filter and purify the liquid collected by the humidification vortex tube 41 to prevent air pollution from being blown into the underground construction environment during the air humidification process.

[0062] It should be noted that: the spherical filter 12 with a convex surface arranged on the air outlet side of the humidifying pipe 4 and the dehumidifying pipe 5 can filter the air passing through the humidifying pipe 4 and the dehumidifying pipe 5 at a high speed, thereby increasing the wind pressure bearing capacity of the spherical filter 12 during filtering. At the same time, when the air passes through the spherical surface of the spherical filter 12, the contact area between the air and the spherical filter 12 can be expanded, thereby improving the air purification efficiency.

[0063] Based on the above, when the humidifying vortex tube 41 rotates in reverse, the air moisture captured by the dehumidification purification net 51 will be transported to the ultrasonic atomization tube 42, and when passing through the dust filter tube 421, the recovered water can be filtered to avoid direct atomization by the ultrasonic atomization tube 42, so that impurities in the water float in the air and cause air pollution;

[0064] Based on the above, when the air passes through the capillary structure of the cooling tube 3, the humidification purification net 411 arranged between the humidification vortex tube 41, and the moistened dehumidification purification net 51, impurities in the air can be filtered, thereby improving the filtering capacity of the air purification tube 1 for the air.

[0065] Working principle:

[0066] The present invention is divided into an air control process and an air purification process when purifying the air at the air inlet. The air control process is divided into: an air temperature control process and a humidity control process. In the control process, the air flow control process in the air purification tube 1 is completed by the ventilation control component, wherein the air temperature control process is divided into a cooling control process and a heating control process, specifically: when the air needs to be cooled through the air purification tube 1, the ventilation control component is used to control the air to pass through the cooling tube 3, and the air throttling expansion cooling principle is used to make the high-pressure air pass through the cooling tube 3 of the throttling expansion capillary copper tube. The temperature on the air outlet side of the temperature control component is reduced, thereby achieving the purpose of cooling the air;

[0067] When the air needs to be heated up through the air purification tube 1, the ventilation control component controls the air to pass through the heating tube 2, and turns on the electric heating rod, so that the heating rod 21 heats the air, and the temperature on the air outlet side of the temperature control component increases, thereby achieving the purpose of heating the air;

[0068] Based on the above, when the air is only transported to the air outlet side of the temperature control component through the heating tube 2, the air squeezes the closing plug 24, and when its air pressure is greater than the elastic force of the compression spring 25, the vent 23 is connected with the heating tube 2, and when the air pressure in the heating tube 2 is lower than the elastic force of the compression spring 25, the vent 23 is closed, so that the air entering the heating tube 2 undergoes an intermittent compression process, thereby extending the contact time between the air and the heating rod 21 and improving the air heating capacity.

[0069] Based on the above, the humidity control process of the air is divided into a humidification process and a dehumidification process, specifically: when the air needs to be humidified, the air regulated by the temperature control component is passed through the humidification tube 4 only through the ventilation control component, and when passing through the humidification vortex tube 41, the air is preliminarily humidified through the humidification purification net 411 connected to the outside thereof, and the water contained in the ultrasonic atomization tube 42 is atomized by the ultrasonic atomizer, and the air after passing through the spherical filter 12 can be further humidified, thereby improving the air humidification capacity;

[0070] When the air needs to be dehumidified, the ventilation control component will allow the air regulated by the temperature control component to pass only through the dehumidification pipe 5, and when passing through the dehumidification pipe 5, the air will be cooled by the dehumidification purification net 51 made of heat-conducting metal, so that the air can capture gaseous water when passing through, thereby achieving the purpose of air dehumidification.

[0071] Based on the above, when the air passes through the humidification and purification net 411, it can drive the humidification vortex tube 41 to rotate, and the water contained in the humidification tube 4 is reversely transported to the ultrasonic atomization tube 42, so that the water captured by the dehumidification and purification net 51 is recycled, and when the humidification tube 4 rotates, the humidification and purification net 411 can be submerged below the water surface, thereby increasing the moisture contained in the humidification and purification net 411, so that when the air passes through the humidification tube 4, the water-rich humidification and purification net 411 can improve the initial humidification capacity of the air.

[0072] Based on the above, the air flow control process in the air purification tube 1 is as follows: when the air needs to be aligned and cooled through the temperature control component, the stepper motor 64 located on the temperature control ventilation disk 61 is started, so that the low-temperature ventilation hole 611 is connected with the cooling tube 3, and the heating tube 2 is closed, so that the air can only be transported to the humidity control component through the cooling tube 3;

[0073] Similarly, when the air needs to be aligned and heated when passing through the temperature control component, the temperature control ventilation disk 61 is controlled to rotate so that the low-temperature ventilation hole 611 is misaligned with the cooling tube 3, and the blockage of the heating tube 2 is released, so that the air can only be transported to the humidity control component through the heating tube 2, thereby completing the ventilation control operation during the air temperature control process.

[0074] Based on the above, when the air needs to be aligned and humidified after passing through the humidity control component, the stepper motor 64 located on the humidity control ventilation disk 62 is started, so that the through hole set on the humidity matching disk 63 is aligned with the pipe opening of the humidification tube 4, and the ventilation channel of the dehumidification tube 5 is closed, so that the air after temperature control only passes through the humidification tube 4, and is humidified by the humidification purification net 411 and the ultrasonic atomization tube 42;

[0075] Similarly, when the air needs to be dehumidified after passing through the humidity control component, the humidity control ventilation disk 62 is controlled to rotate so that the through hole set on the humidity matching disk 63 is aligned with the pipe mouth of the dehumidification tube 5, so that the air after temperature control only passes through the dehumidification tube 5, and the moisture contained in the air is captured by the dehumidification purification net 51 to achieve the purpose of dehumidification, thereby completing the ventilation control operation in the process of air humidity control.

[0076] Based on the above, when the cooled air needs to be dehumidified, the stepper motor 64 arranged on the top of the humidity control ventilation disk 62 drives the humidity control ventilation disk 62 to rotate, and after the rotation, the through hole in the humidity control ventilation disk 62 is connected with the dehumidification pipe 5, and the dehumidification matching net 631 rotates to align with the area where the cooling pipe 3 is located, that is, to align with the area where the low-temperature ventilation hole 611 is located, so that the dehumidification matching net 631 can contact with the air after passing through the cooling pipe 3, and the dehumidification matching net 631 arranged by the heat conductive material can preliminarily capture the moisture in the air;

[0077] When the cooled air needs to be humidified, the humidity control ventilation disk 62 is rotated 180 degrees so that the dehumidification matching net 631 is not aligned with the area where the cooling tube 3 is located, so that the air passing through the cooling tube 3 directly enters the humidification tube 4 for humidification, and the passing air is not blocked to avoid affecting the subsequent humidification effect.

[0078] Based on the above, when the heated air needs to be dehumidified, the humidity control ventilation disk 62 is rotated so that the dehumidification matching net 631 is aligned with the vent 23, so that it can contact the air after passing through the heating pipe 2, and initially capture the moisture in the air, so that the dehumidification matching net 631 cooperates with the dehumidification purification net 51 to capture the moisture of the passing air twice, thereby achieving the effect of improving the air dehumidification capacity;

[0079] When the heated air needs to be humidified, the humidity control ventilation disk 62 is rotated 180 degrees so that the dehumidification matching net 631 is not aligned with the vent 23, so that the air passing through the heating tube 2 directly enters the humidification tube 4 for humidification without blocking the passing air, thereby avoiding affecting the subsequent humidification effect;

[0080] Based on the above, when filtering and purifying the air, the spherical filter 12 with a convex surface arranged on the air outlet side of the humidification tube 4 and the dehumidification tube 5 can filter the air passing through the humidification tube 4 and the dehumidification tube 5 at a high speed, thereby increasing the wind pressure bearing capacity of the spherical filter 12 during filtering. At the same time, when the air passes through the spherical surface of the spherical filter 12, the contact area between the air and the spherical filter 12 can be expanded, thereby improving the air purification efficiency.

[0081] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
