Description
Technical field
The utility model relates to a kind of jetting type thrust ventilation smoke extraction systems, belong to ventilation smoke exhaust technical field.
Background technique
In order to improve the ventilated environment of underground parking, need that ventilation smoke extraction system is installed in underground parking.Currently, ground
The ventilation smoke extraction system in lower parking lot is usually to be made of breeze fan, smoke exhaust fan, ventilation shaft, and breeze fan stops to underground
Fresh air is sent into parking lot, and parking lot will be discharged containing the flue gas of tail gas, dust in smoke exhaust fan.The major defect of the system is to be
System arrangement is cumbersome, and construction workload is big, at high cost, ventilating system overall efficiency less than 50%, generate energy waste and operation at
This increase, air output can not be accurately controlled, and there are large area diffusion areas in air flow process, formed air and wrapped
Phenomenon is rolled up, so that the regional gas stream can not achieve air-flow exchange, the vehicle exhaust concentration in ground library cannot unobstructed dilution and discharge.
Summary of the invention
Technical problem to be solved by the utility model is to provide a kind of jetting type thrust ventilation smoke extraction systems, it is solved
Determined current underground parking ventilation smoke extraction system ventilation smoke exhaust low efficiency the problem of.
Technical problem to be solved in the utility model takes following technical scheme to realize:
A kind of jetting type thrust ventilation smoke extraction system, it includes reversible jet blower, ventilation duct, branch pipe, diffusion shell, cambered surface
The multiple reversible jet blowers being fixed at the top of underground parking are sequentially communicated by pod, the ventilation duct, on the downside of ventilation duct
Equipped with more branch pipes, branch infratubal port is equipped with diffusion shell, and branch pipe upper port is equipped with cambered surface pod, and diffusion shell is horn-like cover
Body, cambered surface pod is by the outlet air smooth guide of branch pipe upper port to tube axis direction of divulging information.
As preferred embodiment, angle is a between the branch pipe and ventilation duct, 10 °≤a≤45 °.
The beneficial effects of the utility model are: smoke discharging function, starts reversible jet blower, when ventilation duct interior air-flow direction with
When cambered surface pod air-out direction is identical, air-flow forms negative pressure in branch pipe upper port, and tail gas, dust will be full of in underground parking
Air by more reversible jet blower relays, underground parking is discharged in pollution air by branch pipe suction ventilation pipe；
Ventilation function controls reversible jet blower reversion, and ventilation duct interior air-flow direction blows to cambered surface pod entrance at this time, passes through ventilation
Pipe is pumped into fresh air from outside, enters branch pipe by cambered surface pod, blows to underground parking, guarantees that air is fresh；Under branch pipe
Port is equipped with diffusion shell, is conducive to improve ventilation smoke exhaust effect；Branch pipe inclination is connect with ventilation duct, is conducive to the water for improving air-flow
Flat speed drives the air of entire underground parking to flow according to the direction of ventilation duct, improves ventilation smoke exhaust efficiency.
Detailed description of the invention
Fig. 1 is the utility model smoke evacuation status architecture schematic diagram；
Fig. 2 is the utility model ventilation state structural schematic diagram.
In figure: reversible jet blower 1, ventilation duct 2, branch pipe 3, diffusion shell 4, cambered surface pod 5.
Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness to the utility model are easy to understand, tie below
Conjunction is specifically illustrating, and the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of jetting type thrust ventilation smoke extraction system, it include reversible jet blower 1, ventilation duct 2,
Branch pipe 3, diffusion shell 4, cambered surface pod 5, ventilation duct 2 will be fixed on multiple reversible jet blowers 1 at the top of underground parking according to
Secondary connection is equipped with more branch pipes 3 on the downside of ventilation duct 2, and 3 lower port of branch pipe is equipped with diffusion shell 4, and 3 upper port of branch pipe is led equipped with cambered surface
Stream cover 5, diffusion shell 4 are horn-like cover, and cambered surface pod 5 is by the outlet air smooth guide of 3 upper port of branch pipe to 2 axis of ventilation duct
Direction.Two reversible jet blowers 1 are only drawn in figure and pass through the structural schematic diagram that is connected to of ventilation duct 2, and actual conditions are, can basis
Underground parking concrete shape, reasonable layout more reversible jet blowers 1, is sequentially connected two-by-two, beginning, the end of whole system
It is connected to by ventilation duct 2 with the fresh air on ground.
Angle is a between branch pipe 3 and ventilation duct 2,10 °≤a≤45 °.That is the inclination of branch pipe 3 is connect with ventilation duct 2.
Working principle:
Smoke discharging function starts reversible jet blower 1, when 2 interior air-flow direction of ventilation duct and 5 air-out direction phase of cambered surface pod
Meanwhile air-flow forms negative pressure in 3 upper port of branch pipe, the air of tail gas, dust will be full of in underground parking, be sucked by branch pipe 3
In ventilation duct 2, by more reversible 1 relays of jet blower, underground parking is discharged in pollution air.
Ventilation function controls reversible jet blower 1 and inverts, and 2 interior air-flow direction of ventilation duct blows to cambered surface pod 5 and enters at this time
Mouthful, fresh air is pumped into from outside by ventilation duct 2, branch pipe 3 is entered by cambered surface pod 5, blows to underground parking, is guaranteed empty
Gas is fresh.
By controlling reversible 1 positive and negative alternate of jet blower rotation, smoke discharging function and ventilation function are used alternatingly, can either arrange
Air is polluted out, and can be passed through fresh air.
3 lower port of branch pipe is equipped with diffusion shell 4, is conducive to improve ventilation smoke exhaust effect；The inclination of branch pipe 3 is connect with ventilation duct 2,
The horizontal velocity for being conducive to improve air-flow drives the air of entire underground parking to flow according to the direction of ventilation duct 2, improves logical
Wind smoke exhaust efficiency.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
