Problems solved by technology

During the construction process of personnel, breathing, material oxidation and other gas overflow will cause the concentration of oxygen in the air in the tunnel to drop sharply, resulting in insufficient oxygen supply.
Solid particles such as coal dust and rock dust will also be produced in the tunnel, and these factors will pose a threat to the safety of construction personnel

Embodiment 1

[0034] Example 1: Isolated ventilation in narrow tunnels

[0035] according to figure 1 with figure 2 As shown, it includes tunnel ventilation sub-module, monitoring module, information transmission sub-module, interval control module and central control module: the tunnel ventilation sub-module sends new air into the tunnel through the fan while removing the contaminated air to make the tunnel The concentration of pollutants is not too high, so as to ensure that the gas in the tunnel has a higher visibility and harmful gases at a lower concentration; the monitoring module consists of CO / NO2 concentration detector, smoke concentration detector, and vehicle information detection information Its main function is to complete the transmission of various information in the tunnel: such as the ventilation effect in the tunnel, the concentration of CO / NO2, the concentration of smoke, and the traffic flow. The information is transmitted to the interval control module through the informat...

Abstract

The invention discloses a technology of high-efficiency energy-saving extra-long tunnel ventilation and ventilation under the multiple operating conditions. The technology of high-efficiency energy-saving extra-long tunnel ventilation and ventilation under the multiple operating conditions comprises a tunnel ventilation submodule, a monitoring module, an information transmission submodule, an interval control module and a center control module, wherein the tunnel ventilation submodule feeds fresh air into a tunnel through a fan and eliminates polluted air at the same time, so that the pollutant concentration in the tunnel is not excessive, gas in the tunnel is ensured to have higher visibility, and harmful gas is at lower concentration. According to the technology of high-efficiency energy-saving extra-long tunnel ventilation and ventilation under the multiple operating conditions provided by the invention, through an extra-long harmful gas tunnel ventilator remote central control system, the fan is remotely controlled and automatically controlled, and corresponding measures are further taken according to the special circumstances of the tunnel so as to ensure the safety operationof the system, so that the probability of the damage of the fan is effectively reduced, and the working efficiency is improved.

Description

Technical field [0001] The invention relates to a super-long tunnel ventilation technology, in particular to a super-long tunnel high-efficiency energy-saving automatic ventilation and ventilation technology under multi-operation conditions, and belongs to the technical field of super-long tunnel ventilation. Background technique [0002] The construction of transportation infrastructure is the lifeline of the development of the national economy. About 75% of my country's land is mountainous or uphill, which makes tunnels play a vital role in transportation construction. According to statistics, as of the end of 2018, my country's railway operating mileage has reached 13,100km, and the railway tunnels in operation are 16,331km. The total length of railway tunnels under construction in my country is 7,465km, and the total length of railway tunnels is about 156834km. However, the construction of extra-long hazardous gas tunnels has brought unprecedented challenges to tunnel workers...
