Summary of the invention of the present utility model is that a kind of subway sectional tunnel dust removal by ventilation structure, comprises and be arranged at the interlayer of tunnel top and be arranged at electrostatic precipitator, flushing machine, the Shou Shui mechanism in described interlayer; Described interlayer two ends have opening, and the direction of opening parallels with the direction of traffic of locomotive in service in subway sectional tunnel; Described flushing machine can rinse electrostatic precipitator, and Shou Shui mechanism comprises blowoff basin, draining pump, rinses electrostatic precipitator water and flows into blowoff basin, and draining pump is arranged in blowoff basin, blowoff basin water is discharged.
One of preferred version of the present utility model, the installation clearance between electrostatic precipitator and interlayer, tunnel top is by shutoff, and the dust-contained airflow that enters interlayer can only pass through electrostatic precipitator.
One of preferred version of the present utility model, blowoff basin comprises mud sump, collecting-tank, and mud sump is collected and is rinsed electrostatic precipitator current, and mud sump water flows into collecting-tank completely afterwards, and draining pump is located in collecting-tank.
One of preferred version of the present utility model, in described interlayer, before and after electrostatic precipitator, two sides are respectively equipped with an air pressure determinator, and air pressure determinator is the air pressure of the real time measure electrostatic precipitator two sides respectively, and air pressure determinator and controller are electrically connected.
One of preferred version of the present utility model, draining pump is the submersible sewage pump that carries backwash.
The utility model has the advantage of, simple in structure, effectively to utilize Piston Action Wind and without extra power, make full use of tunnel expanding reach remaining space, dust removal process is effective.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Dust removal by ventilation structure comprises and is arranged at the interlayer 1 of tunnel top 4 and is arranged at electrostatic precipitator 2, flushing machine, the Shou Shui mechanism in described interlayer 1; Interlayer 1 two ends have opening, the direction of opening parallels with the direction of traffic 3 of locomotive in service in subway sectional tunnel, be respectively equipped with an air pressure determinator 8 in interior electrostatic precipitator 2 front and back two sides of interlayer 1, air pressure determinator 8 is the air pressure of the real time measure electrostatic precipitator 2 two sides respectively, and air pressure determinator 8 is electrically connected with controller; Installation clearance between electrostatic precipitator 2 and interlayer 1, tunnel top 4 is by shutoff, and the dust-contained airflow (Piston Action Wind 9) that enters interlayer 1 can only pass through electrostatic precipitator 2; Flushing machine can rinse electrostatic precipitator 2, Shou Shui mechanism comprises blowoff basin, draining pump 5, draining pump 5 is for carrying the submersible sewage pump of backwash, blowoff basin comprises mud sump 6, collecting-tank 7, mud sump 6 is collected and is rinsed electrostatic precipitator 2 current, mud sump 6 water flow into collecting-tank 7 completely afterwards, and draining pump 5 is located in collecting-tank 7.
When work, enter the piston air quantity in tunnel expanding reach equipment interlayer 1 by ground iron hoop control simulation softward (being called for short " SES ") calculative determination, calculate the wind area excessively of dedusting panel according to the requirement of electrostatic precipitator filter dirt wind speed, carry out rational lectotype selection, electrostatic precipitator 2 joins with station comprehensive monitoring system, realizes the real-time monitoring and control of equipment.According to gauge and dust collecting process requirement, reasonably determine the interior relevant device of interlayer 1 and the arrangement of pipeline and the structural thickness of interlayer 1 plate, and interlayer 1 structural slab is carried out to structurally waterproof design, interlayer 1 platform arranges dash platform, access path and certain hydraulic gradient, platform surface requires smooth, smooth, and tunnel-side arranges maintenance steel cat ladder.Cross wind area according to the electrostatic precipitator 2 after type selecting, by 2L/m2 configuration wash water amount; Draw the feed pipe of a DN25 as the water-supply source of flushing machine by contiguous station, tubing adopts external galvanized layer plastic-lined steel pipe, and flushing machine washing pressure is by being not less than 0.1Mpa design; In tunnel expanding reach Nei Sheshoushui mechanism, Shou Shui mechanism is divided into two lattice, the first lattice be aim at rinse electrostatic precipitator use mud sump 6, for process rinse after contain mud waste water; The second lattice collecting-tank 7, collecting-tank 7 is collected the waste water after the overflow of mud sump precipitation, utilizes draining pump 5 to discharge after collection.Draining pump 5 adopts the submersible sewage pump that carries backwash, before the each startup of submersible sewage pump, all first carries out backwash, partial product is stored in to the sludge agitation of collecting-tank 7, is then communicated with waste water and gets rid of together; Consider limited space between Close Tunnel, drainpipe is set separately and is unfavorable for that between Close Tunnel, gauge is arranged, therefore by waste water house steward between pump drain pipe access area, utilize interval waste pipe to be expelled to pressure outside waste water well; Real monitoring when the air pressure of electrostatic precipitator 2 two sides is carried out that electrostatic precipitator 2 two sides are provided with air pressure determinator 8, judges whether fault or cleaning of deduster according to the signal of electrostatic precipitator 2 two side air pressure differences feedbacks.
In sum, be only the preferred embodiment of the utility model, do not limit protection domain of the present utility model with this, all equivalences of doing according to the utility model the scope of the claims and description change and modify, within being all the scope that the utility model patent contains.
