中国专利公布号CN102482943A公开一种隧道通风设备,为净化包含车辆通行用隧道在内的一般隧道内部的空气,同时将隧道内部被污染的空气排出到外部,在隧道内部地面上以一定间隔设置一列大小不同的多个储水罐,通过供给冷空气与车辆产生的被污染的热空气产生对流,使其中重量较重的煤烟及尾气被储水罐吸收,重量较轻的污染气体通过烟囱排出到外部,使隧道内部空气始终保持清新,营造舒适的隧道环境,而且在隧道内发生火灾时,能够喷射消防水进行灭火。该发明为实现隧道内部空气的自然循环,将储水罐设施产生的对流现象和烟囱效果相结合,使污染空气自然排出,该发明与以往使用排风扇进行通风的方式不同,不会产生噪音,也不会发热,而且没有电力消耗,能够降低经济损失。Chinese Patent Publication No. CN102482943A discloses a tunnel ventilation device. In order to purify the air inside a general tunnel including the tunnel for vehicles, and discharge the polluted air inside the tunnel to the outside, a row of ventilation equipment is arranged on the ground inside the tunnel at certain intervals. Multiple water storage tanks of different sizes, through the supply of cold air and the polluted hot air generated by the vehicle, generate convection, so that the heavier soot and exhaust gas are absorbed by the water storage tanks, and the lighter pollutant gases are discharged through the chimney To the outside, the air inside the tunnel is always kept fresh, creating a comfortable tunnel environment, and when a fire breaks out in the tunnel, firefighting water can be sprayed to extinguish the fire. In order to realize the natural circulation of the air inside the tunnel, this invention combines the convection phenomenon generated by the water storage tank facilities with the chimney effect to let the polluted air be discharged naturally.

由于隧道狭窄,通风不良,往往会堆积许多的废气、尘埃,这些污染对人体的眼睛和呼吸道有刺激作用,易诱发各种炎症,轻者眩晕、头痛,重者将受到永久性损伤;而尘埃颗粒还会引发肺部疾病,使隧道内人员的健康难以保证。因此,寻求一种效果良好的控制隧道环境的方法,已经成为城市公路隧道建设中急需解决的问题之一。目前,隧道的通风基本是通过安装大型的鼓风机来实现的,这种噪音大,对长的隧道通风效果也很差。因此,本发明提供一种新的隧道粉尘的去除方法,能有效去除有害气体和粉尘,以弥补现有技术中的不足。Due to the narrow tunnel and poor ventilation, a lot of exhaust gas and dust are often accumulated. These pollutions can irritate the eyes and respiratory tract of the human body, and easily induce various inflammations. In mild cases, dizziness and headaches, in severe cases, will be permanently damaged; while dust Particles can also cause lung disease, making it difficult to ensure the health of those inside the tunnel. Therefore, seeking a method with good effect to control the tunnel environment has become one of the urgent problems to be solved in the construction of urban highway tunnels. At present, the ventilation of tunnels is basically achieved by installing large blowers, which are very noisy and have a poor ventilation effect on long tunnels. Therefore, the present invention provides a new method for removing tunnel dust, which can effectively remove harmful gas and dust, so as to make up for the deficiencies in the prior art.
