Large tunnel dust removal plant and dust removal method thereof

Abstract

The invention discloses a large tunnel dust removal plant and a dust removal method thereof. The dust removal plant comprises a dust removal electric control group and a dust removal operation group; wherein, the dust removal electric control group comprises an equipped distribution and control chamber and an equipped electric power chamber; the dust removal operation group comprises a 1# operation room, a 2# operation room, a 3# operation room and a 4# operation room. The method of the invention comprises the following steps: an operation car adopts a high-pressure dust blower to blow dust toward the bottom surface and the sides; dust collection ports are respectively arranged in the upper, lower, left and right directions, so as to form spatially closed dust collection; the direction of air flow is adjusted by opening a pneumatically reversible air door; the dust collection ports are combined with air outlets so as to form an air curtain to block leakage of dust, after the dust is filtered, clean air is exhausted through a dust collection blower, thus completing dust removal operation. The air doors can be combined in different directions to complete forward or backward dust removal operation. The invention adopts modular design, is convenient for transport, has the advantages of high efficiency, low cleaning cost, good use effect, safety, reliability and the like, and is suitable for tunnel dust removal of railways and highways.

Description

technical field [0001] The invention relates to a dedusting device, in particular to a large-scale tunnel dedusting equipment and a dedusting method thereof. Background technique [0002] Tunnel dust is a major problem that plagues the normal use of tunnels and affects the safe running of trains. In the actual tunnel, due to the dust left over from the construction and the dry climate in the north, it is difficult to harden the dust on the ballastless track. When a train passes by, the tunnel is filled with dust, and the rails and even the lights cannot be seen clearly. The catenary power supply system of electrified railway tunnels has caused great harm, and it has also had a bad impact on the health of the operators in the tunnel and the passengers on board. In the prior art, clear water is mainly used to flush the tunnel and manually clean the ground to alleviate the problem. This method not only wastes water sources, but also has high cleaning costs, and the treatment ...
