Abstract
Automatic sprinkler fire-extinguishing system is cleaned in the tunnel dedusting that the utility model provides, comprise the PM sensor be arranged in tunnel, control device, suction pump, water supply line, several sparge pipes with shower nozzle and ponding well, described ponding well location is in tunnel's entrance and exit end, described water supply line is communicated with ponding well, suction pump is provided with at water supply line and ponding well junction, described control device to be arranged on water supply line and to be electrically connected with suction pump and PM sensor respectively, and described sparge pipe is communicated with water supply line and is disposed on above it.The utility model structure is simple, easily implements.Automatic sprinkler fire-extinguishing system is cleaned in tunnel dedusting, effectively can reduce the pernicious gas in tunnel and suspended particulate substance (PM), clean tunnel road surface and abutment wall, for tunnel operation provides the operating environment of high-quality, with low cost, is suitable for applying.
Description
Technical field
The utility model relates to the dedusting of a kind of tunnel and cleans automatic sprinkler fire-extinguishing system.
Background technology
Along with the development of communication, the proportion of highway tunnel shared by whole circuit is increasing.Tunnel is a relatively inaccessible space, and tunnel internal contamination air not easily spreads, and causes the concentration of pollutant in tunnel air constantly to increase, tunnel road surface and abutment wall vulnerable to pollution, needs regularly and irregular cleaning.
At present, generally adopt ventilation method to dilute, control the concentration of pollutant in tunnel air both at home and abroad, use pavement cleaning to clear up the inside, but abutment wall is cleared up.Along with vehicle flowrate increases, flue dust more and more becomes the primary pollution source in tunnel, especially very large to the ventilation needed for super long tunnel dilution flue dust, simple rely on ventilation dilution flue dust can cause ventilation system cost of erection and energy consumption excessive, Technical Economy is very poor.Sometimes have to increase tunnel cross-section or arrange airshaft, to meet air-conditioning requirement, and this must cause increasing initial investment and operating cost.
Therefore, automatic sprinkler fire-extinguishing system Be very effective is cleaned in tunnel dedusting, and efficiency of dust collection reaches more than 90%, can automated cleaning tunnel road surface and abutment wall.Adopt in long highway tunnel dedusting clean automatic sprinkler fire-extinguishing system can improve highway tunnel inside operating environment, save construction cost, reduce and mainly contain poisonous gas, clean tunnel internal in cost of business operation and removing tunnel, the development of highway in China traffic is significant.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model provides the tunnel dedusting that a kind of structure is simple, cost is low, effective to clean automatic sprinkler fire-extinguishing system.
To achieve these goals, the utility model provides following technical scheme: automatic sprinkler fire-extinguishing system is cleaned in the dedusting of a kind of tunnel, comprise the PM sensor be arranged in tunnel, control device, suction pump, water supply line, several sparge pipes with shower nozzle and ponding well, described ponding well location is in tunnel's entrance and exit end, described water supply line is communicated with ponding well, suction pump is provided with at water supply line and ponding well junction, described control device is arranged on water supply line, and be electrically connected with suction pump and PM sensor respectively, described sparge pipe is communicated with water supply line and is disposed on above it.
As preferably, described water supply line has two, is arranged at both sides, tunnel respectively.
As preferably, described shower nozzle is rotary nozzle.
As preferably, interval 2-5m between described adjacent two sparge pipes.
Can be found out by above technical scheme, the utility model structure is simple, easily implements.Automatic sprinkler fire-extinguishing system is cleaned in tunnel dedusting, effectively can reduce the pernicious gas in tunnel and suspended particulate substance (PM), clean tunnel road surface and abutment wall, for tunnel operation provides the operating environment of high-quality, with low cost, is suitable for applying.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is front view of the present utility model.
Detailed description of the invention
The utility model is further described below in conjunction with specific embodiment and accompanying drawing.
Automatic sprinkler fire-extinguishing system is cleaned in a kind of tunnel dedusting as shown in Figures 1 and 2, comprise the PM sensor 1 be arranged in tunnel, control device 2, suction pump 3, water supply line 4, several sparge pipes 5 with shower nozzle 6 and ponding well 7, described ponding well 7 is positioned at tunnel's entrance and exit end, described water supply line 4 is communicated with ponding well 7, suction pump 3 is provided with in water supply line 4 and ponding well 7 junction, described control device 2 is arranged on water supply line 4, and be electrically connected with suction pump 3 and PM sensor 1 respectively, described sparge pipe 5 is communicated with 4 with water supply line and is disposed on above it.
As preferably, described water supply line 4 has two, is arranged at both sides, tunnel respectively.
As preferably, described shower nozzle 6 is rotary nozzle.
As preferably, interval 3m between described adjacent two sparge pipes 5.
After PM sensor 1 senses that PM value reaches preset value, suction pump 3 is opened by control device 2, water is extracted out from ponding well 7, sparge pipe 5 is entered by water supply line 4, sprayed at tunnel internal by shower nozzle 6 again, effectively can improve the operating environment of highway tunnel inside, save construction cost, reduce and mainly contain poisonous gas, clean tunnel internal in cost of business operation and removing tunnel, the development of highway in China tunnel operation is significant.
Above the technical scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, detailed description of the invention and range of application all will change, and in sum, this description should not be construed as restriction of the present utility model.
