Embodiment

[0091] Take a certain extra-long highway tunnel as an example. The highway tunnel is a world-class extra-long tunnel, and the operational safety issues are very prominent. For the safety of tunnel driving, two 24-hour manned fire protection duty rooms are set up inside the tunnel. The duty room at the north entrance is located in the horizontal tunnel of the 8# vehicle, and the pile number is K70+785.08. The duty room at the south entrance is located in the horizontal tunnel of the 17# vehicle, and the pile number is K76+785.08. Each fire duty room is 5m long, 6m wide and 3m high. Duty room volume is 90m 3 , with an area of ​​about 30m 2 , the number of people is 2, the number of air changes is 6 times / h, and the required air volume is L=90*6=540m 3 / h=0.15m 3 / s.

[0092] Take No. 8 duty room as an example, the system equipment is in accordance with this plan figure 1 layout in the format.

[0093] The duty room covers an area of ​​30 square meters, and the fresh air i...

Abstract

The invention discloses a combined air purifying system and method for a duty room in an ultralong highway tunnel. The combined air purifying system comprises an outdoor purifying and filtering unit arranged in a tunnel lane horizontal adit, filtering devices, a flow mixing cavity and an air supply device are arranged in the outdoor purifying and filtering unit, the filtering devices are arranged on two sides of the flow mixing cavity, and air collected from the tunnel enters the flow mixing cavity after passing the filtering device on one side of the flow mixing cavity, passes the filtering device on the other side of the flow mixing cavity after being mixed with air guided out from the duty room in the flow mixing cavity, and is fed into the duty room through the air supply device. Air purifying technology and oxygen generating technology are combined and applied to improving air quality of the duty room of the ultralong highway tunnel, an air purifying, circulating and controlling method capable of meeting needs of working staff for 24h's work is provided, purifying efficiency can be improved to greatest extent, maintenance frequency is reduced, activated carbon regeneration times are reduced especially, and operation cost is lowered.

Description

technical field [0001] The invention relates to a combined air purification system and method for a duty room in an extra-long highway tunnel, in particular to an air circulation purification and oxygen-generating combined device for a closed special duty room in an extra-long highway tunnel, and a monitoring and control system and method thereof. Background technique [0002] With the development of my country's road transport industry, the number and scale of road tunnels are constantly increasing. For extra-long highway tunnels, the problems of tunnel operation safety and disaster prevention and rescue are very prominent. For fire prevention and quick treatment, a special duty room is set up at the vehicle cross passage inside the tunnel, and firefighters are on duty 24 hours a day, which greatly improves the safety of tunnel operation. However, with the increase of traffic flow, the air quality in the tunnel decreases, and the duty room is generally located in the middl...
