Description

Technical Field

[0001] The utility model relates to the technical field of tunnel ventilation and purification, in particular to a tunnel ceiling type purification station structure. Background Art

[0002] Highway tunnels are long and narrow and relatively closed. They are semi-enclosed spaces with poor ventilation conditions. Natural ventilation alone cannot guarantee the air quality in the tunnel. The harmful gases (smoke, NO2, etc.) emitted by cars driving in the tunnel are difficult to be discharged to the outside. A large amount of polluted air reduces the air quality in the breathing area of ​​the tunnel. When the harmful gases accumulate to a certain extent, they will threaten human health and even affect driving safety. When the closed section of the tunnel is long, even if mechanical ventilation is used, it is difficult to effectively control pollutants to below the limit.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0024] It should be noted that the terms "including" and "having" and any variations thereof in the embodiments of the present application and the accompanying drawings are intended to cover non-exclusive inclusions. For example, a series of structures are included, which is not limited to the listed structures, but may optionally include structures not listed, or may optionally include other components inherent to these structures.

[0025] The embodiment of the present application discloses a tunnel ceiling purification station structure, which adopts a tunnel pollution control method of air purification and can be applied to various forms of tunnels. Detailed descriptions are given below.

[0026] Figure 1 and Figure 2 A tunnel ceiling purification station structure provided according to an embodiment of the present application is shown. Figure 1 and Figure 2 As shown, the structure of the tunnel ceiling purification station mainly includes: a purification station cavity 1, a purification component 2, an air inlet 3 and an air outlet 4. Specifically, the purification station cavity 1 is arranged at the top 51 ceiling of the tunnel 5, which is concave from the top of the tunnel 5 to the direction away from the tunnel 5 to form a relatively closed cavity, mainly to provide a placement space for the purification component 2, which is arranged at the top 51 ceiling of the tunnel 5, that is, most of the structure of the tunnel ceiling purification station structure is arranged at the top 51 ceiling of the tunnel 5, and the internal space of the tunnel 5 is not occupied as much as possible to avoid affecting the driving height of the tunnel 5. The purification component 2 is an air purification component of the tunnel ceiling purification station structure, which is arranged in the purification station cavity 1 to purify the dirty air in the tunnel 5. The air inlet 3 and the air outlet 4 are respectively arranged at the two ends of the tunnel ceiling purification station structure. The air inlet 3 connects the purification station cavity 1 and the tunnel 5, and is located on the air inlet end side of the purification component 2, so that the dirty air in the tunnel 5 is guided to the air inlet end of the purification component 2 through the air inlet 3, and then the dirty air is purified by the purification component 2. The air outlet 4 also connects the purification station cavity 1 and the tunnel 5, and the air outlet 4 is located on the air outlet end side of the purification component 2, so that the purified purified airflow is transported back to the tunnel 5 through the air outlet 4. In the embodiment of the present application, the air outlet direction of the air inlet 3 is perpendicular to the driving direction of the tunnel 5. In further detail, the air inlet 3 is arranged on the top 51 of the tunnel 5. The design of the air inlet 3 makes the air inlet passage shorter, which is more conducive to the dirty air in the tunnel 5 to enter the purification station cavity 1 faster and more, and then be purified by the purification component 2, and the purification efficiency is higher. In addition, the air outlet direction of the air outlet 4 is parallel to the driving direction of the tunnel 5, avoiding the safety risk caused by the high-speed purified air flow blowing directly downward and colliding with the driving vehicles at the bottom of the tunnel 5, and the safety is high.

[0027] like Figure 1As shown, the air in the tunnel 5 flows into the purification station cavity 1 through the air inlet 3, and forms a purified airflow through the purification component 2. The purified airflow flows into the tunnel 5 through the air outlet 4, and the outflow direction of the purified airflow entering the tunnel 5 is parallel to the driving direction of the tunnel 5. The structure of the tunnel ceiling purification station allows the air containing pollutants in the tunnel 5 to pass through the purification component 2 to form a purified airflow, and then be discharged from the air outlet 4 parallel to the main airflow of the tunnel 5, effectively avoiding the safety risks caused by the high-speed airflow after purification being directly discharged downward into the driving space of the tunnel 5, causing the high-speed jet to collide with the tunnel vehicle, thereby making driving safer. The structure of the tunnel ceiling purification station forms a more effective outflow characteristic by designing the air outlet direction of the air outlet 4, which is conducive to improving the health and safety of the tunnel operation environment.

[0028] In some specific embodiments, Figure 1 and Figure 2 As shown, the purification component 2 includes a coarse filter 21, an electrostatic precipitator 22 and a NO2 filter 23. In detail, along the direction from the air inlet 3 to the air outlet 4, the coarse filter 21, the electrostatic precipitator 22 and the NO2 filter 23 are sequentially arranged in the purification station cavity 1, so that the dirty air in the tunnel 5 flows into the purification station cavity 1 through the air inlet 3, and then flows through the coarse filter 21, the electrostatic precipitator 22 and the NO2 filter 23 in sequence to form a purified airflow, and the purified airflow flows into the tunnel 5 through the air outlet 4. Among them, the coarse filter 21 is mainly used to remove large particles of impurities contained in the dirty air, the electrostatic precipitator 22 is mainly used to remove particulate matter such as smoke and dust contained in the dirty air, and the NO2 filter 23 is mainly used to remove the NO2 component contained in the dirty air.

[0029] Further, such as Figure 1 and Figure 2 As shown, the purification assembly 2 also includes a fan 24. The fan 24 is arranged in the purification station chamber 1, between the NO2 filter 23 and the air outlet 4, and is used to provide power for the flow of purified air. The outlet end of the fan 24 is connected to the air outlet 4, thereby driving the purified air flow from the air outlet 4 into the tunnel 5, further improving the purification efficiency of the tunnel ceiling purification station structure.

[0030] In addition, the purification component 2 also includes a first muffler 25 and a second muffler 26. The first muffler 25 is arranged in the purification station cavity 1, and the first muffler 25 is located between the NO2 filter 23 and the fan 24, and the second muffler 26 is also arranged in the purification station cavity 1, and is located between the fan 24 and the air outlet 4. The first muffler 25 is placed at the front end of the fan 24, and the second muffler 26 is placed at the rear end of the fan 24. By installing the mufflers at the front and rear ends of the fan 24, the noise generated by the operation of the machine can be effectively reduced, and the driving experience of the vehicle in the tunnel 5 can be improved.

[0031] In other specific embodiments, Figure 1 and Figure 2 As shown, the air outlet 4 includes a longitudinal air outlet 41, a transverse air outlet 42, a guide air duct 43 and a longitudinal injection port 44. The longitudinal air outlet 41 is arranged in the purification station chamber 1 and is located between the fan 24 and the guide air duct 43. The longitudinal air outlet 41 connects the guide air duct 43 with the outlet end of the fan 24. In detail, the longitudinal air outlet 41 is arranged corresponding to the fan 24 and the second muffler 26 arranged at the rear end thereof, and the sizes are matched, so that the purified airflow is concentrated and discharged into the guide air duct 43. The guide air duct 43 is arranged at one end of the purification station cavity 1 and is located on the side of the air outlet end of the purification component 2. The transverse air outlet 42 is arranged on the top 51 of the tunnel 5 and is located in the middle of the guide air duct 43. The guide air duct 43 is a spatial structure between the longitudinal air outlet 41 and the transverse air outlet 42. The guide air duct 43 is used to change the flow direction of the purified airflow. The air outlet direction of the transverse air outlet 42 is perpendicular to the driving direction of the tunnel 5, and the transverse air outlet 42 is connected to the guide air duct 43 and the longitudinal injection port 44. The transverse air outlet 42 introduces the purified airflow transported by the longitudinal air outlet 41 into the longitudinal injection port 44. The longitudinal injection port 44 is a tail-sunken structure of the tunnel ceiling purification station structure, which is arranged in the tunnel 5. The air flow outlet of the longitudinal injection port 44 is located at the end of the tail-sunken structure, and the wind direction of the longitudinal injection port 44 is parallel to the driving direction of the tunnel 5, further changing the flow direction of the purified airflow, so that the purified airflow is ejected parallel to the main airflow of the tunnel, and then merged with the main airflow of the tunnel.

[0032] In some specific implementation processes, such as Figure 1 and Figure 2 As shown, the longitudinal injection port 44 includes an integrally connected connection portion and an injection portion 441. Specifically, the connection portion is in a rectangular shape, the connection portion is connected to the guide air duct 43 through the transverse air outlet 42, the injection portion 441 is in an isosceles trapezoidal shape, the long bottom end of the injection portion 441 is connected to the connection portion, the short bottom end 4411 of the injection portion 441 (i.e., the airflow outlet of the longitudinal injection port 44) is connected to the tunnel 5, and the air outlet direction of the injection portion 441 is parallel to the driving direction of the tunnel 5. Through the shape design of the connection portion and the injection portion 441, the airflow inside the injection portion 441 is guided toward the direction of the tunnel 5, so that the purified airflow is gathered and quickly injected into the tunnel 5.

[0033] In other specific implementation processes, such as Figure 1 and Figure 2As shown, the number of fans 24, air inlets 3, longitudinal air outlets 41 and transverse air outlets 42 is multiple, and the fans 24, air inlets 3, longitudinal air outlets 41 and transverse air outlets 42 correspond to each other one by one, and each group of fans 24, air inlets 3, longitudinal air outlets 41 and transverse air outlets 42 are on the same straight line along the center line of the driving direction of the parallel tunnel 5. Further, the number of fans 24, air inlets 3, longitudinal air outlets 41 and transverse air outlets 42 is 2. Of course, the number of fans 24, air inlets 3, longitudinal air outlets 41 and transverse air outlets 42 can be designed according to construction conditions and requirements, and this application does not limit this.

[0034] The tunnel ceiling purification station structure in this application is easy to build and installed on the top of the tunnel, which is conducive to creating a high-quality and safe tunnel driving environment. It can be applied to various types of tunnel projects such as cities and mountain tunnels, especially two-way traffic tunnels or large tunnels where traffic jams often occur. In addition, two-way traffic tunnels or tunnels where traffic jams often occur often use focused smoke exhaust, that is, a dedicated smoke exhaust duct is set in the longitudinal direction of the tunnel. In a tunnel with a smoke exhaust duct, the tunnel ceiling purification station structure can directly use the smoke exhaust duct space for purification operations.

[0035] To sum up, the present application discloses a tunnel ceiling-type purification station structure. Through the design of the overall structure, the purification component is arranged in the purification station cavity, the airflow path is rationalized, and the safety risks caused by the high-speed purified airflow blowing directly downward and colliding with the vehicles in the lower part of the tunnel are avoided. It is beneficial to maximize the purification effect of the tunnel ceiling-type purification station structure, improve the purification efficiency of the dirty air in the tunnel, and thus improve the air quality in the tunnel.
