Abstract
The utility model discloses a system suitable for exhaust air capacity even distribution of an air channels with uniform sections of a subway track area. The system comprises an air channel with uniforms (1), an air draught fan (6) on an air channel port and a plurality of air ports on the air channel wall, wherein the air ports of a pipeline are respectively provided with an air port even distributor (2); internal pipe upwind areas of the air port even distributors (2) gradually increase along the same direction. After the distributor on an air discharging system, even air charging and discharging effect can be achieved without adjustments of each air port capacity based on upwind areas of the even distributors installed before; and draught fan size can be reduced, so energy consumption can be reduced and market promotion and application can be improved.
Description
Technical field
This novel practical relates to rail Hang Qu air channel, ground ventilating system, is specially a kind of uiform section air channel air draft air quantity that is applicable to the capable district of rail, ground and is uniformly distributed system.
Background technology
Along with social development, improving constantly of people's living standard, especially the continuous propelling of urbanization process, use in restricted situation at surface area, underground traffic construction has also obtained development at full speed, the subway construction of big and medium-sized cities is exactly the significant means of transportation that a underground traffic is built.
In existing subway construction and running, can produce a large amount of heats, simultaneously also need enough air to carry out inside and outside exchange, the quality of the ventilating system in Gui Hang district, direct relation the land service condition in the capable district of rail and subway user's traffic safety and riding comfort.An air port is only installed in the air port of traditional exhaust system or air port adds control valve mode; An air port is only installed and generally can not reaches good air blow and return effect; For exhaust system, the air port exhaust air rate near apart from exhaust blower is large, little even calm apart from exhaust blower air port exhaust air rate far away; Make moderate progress although air port adds control valve mode air draft heat extraction effect, regulate equilibrium more difficult, then the resistance that has also increased on the one hand system because having added control valve makes the increase of output power of system fan.
For the device of the ground even air draft in rail Hang Qu air channel, also there is this research on the one hand although at present domestic, only in theory stage, and adopt control valve to adjust, single from regulating the mode of uniformity coefficient to be just not easy to control, and use cost is high, is not easy to apply.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the invention provides one simple in structure, and use cost is cheap, evenly a kind of uiform section air channel air draft air quantity that is applicable to the capable district of rail, ground of air draft successful is uniformly distributed system.
The object of this novel practical is achieved in that
A kind of uiform section air channel air draft air quantity that is applicable to the capable district of rail, ground is uniformly distributed system, comprise uiform section air channel 1, be arranged on several air ports on exhaust blower 6 and the wind path wall of wind passage mouth, it is characterized in that: the air port place in described pipeline is provided with air port uniform distributor 2;
In the pipe of described air port uniform distributor 2, front face area increases in the same direction gradually;
The height of described air port uniform distributor 2 is equal, and width area increases successively;
Described air port uniform distributor 2 width areas are equal, and height area increases successively;
The width of described air port uniform distributor 2 and height area increase successively;
Described air port comprises air inlet 4 and air outlet 5.
actively beneficial effect:this novel practical patent can make air supplying and exhausting system load onto after this distributor, according to the front face area of the even Computation distribution device before installing, do not need to regulate again each tuyere air volume just can reach the uniform effect of supply and exhaust, Fan Selection can reduce on the one hand again, reduce energy consumption, improve its marketing and application.
Brief description of the drawings
Fig. 1 is that air draft air quantity in uiform section air channel is uniformly distributed system schematic;
Fig. 2 is that the air channel air draft air quantity of several uiform section compositions is uniformly distributed system schematic;
In figure, be: uiform section air channel 1, air port uniform distributor 2, air inlet 4, air outlet 5, exhaust blower 6.
Detailed description of the invention
Below in conjunction with accompanying drawing, this novel practical is described further:
A kind of uiform section air channel air draft air quantity that is applicable to the capable district of rail, ground is uniformly distributed system, comprise uiform section air channel 1, be arranged on several air ports on exhaust blower 6 and the wind path wall of wind passage mouth, it is characterized in that: the air port place in described pipeline is provided with air port uniform distributor 2;
In the pipe of described air port uniform distributor 2, front face area increases in the same direction gradually;
The height of described air port uniform distributor 2 is equal, and width area increases successively;
Described air port uniform distributor 2 width areas are equal, and height area increases successively;
The width of described air port uniform distributor 2 and height area increase successively;
Described air port comprises air inlet 4 and air outlet 5.
embodiment 1
A kind of uiform section air channel air draft air quantity that is applicable to the capable district of rail, ground is as shown in Figure 1 uniformly distributed system, in prismatic air channel, even in order to reach the intake at each air outlet 5 places, at air port place, air port uniform distributor 2 is set, the front face area of the air port uniform distributor 2 that air port place arranges is along with the distance of the exhaust blower 6 from uiform section air channel 1 is elongated and increase gradually.
embodiment 2
A kind of uiform section air channel air draft air quantity that is applicable to the capable district of rail, ground is uniformly distributed system as shown in Figure 2, the construction area in rail Hang Qu air channel, base area needs, for the air draft air quantity that reaches whole air channel is uniformly distributed, multiple uiform section air channel air draft air quantity are as shown in Figure 2 uniformly distributed to system and link together by becoming neck place, along with duct cross-section area dwindle and the distance of discharge fan 3 becomes far away and the front face area of air port uniform distributor 2 increases gradually.
This novel practical patent can make exhaust system load onto after this distributor, according to the front face area of the even Computation distribution device before installing, do not need to regulate again each tuyere air volume just can reach the uniform effect of supply and exhaust, Fan Selection can reduce on the one hand again, reduce energy consumption, improve its marketing and application.
Above embodiment is only for illustrating preferred embodiment of the present utility model; but the utility model is not limited to above-mentioned embodiment; in the ken possessing at described field those of ordinary skill; any amendment of doing within spirit of the present utility model and principle, be equal to and substitute and improvement etc., within it all should be encompassed in the technical scheme scope of the utility model request protection.
