Description
Technical field
The utility model relates to a kind of anti-dust storm device, particularly relates to a kind of anti-dust storm ventilation system of motor train unit trailer air-conditioning.
Technical background
Locomotive air conditioner ventilation system in the middle of the prior art, owing to have defective on the structure, under the bigger environment of dust storm, the subject matter that exists on the anti-dust storm effect has: (1) this kind ventilation system structure only is located at the dust storm in the filtering net filtered air of air-conditioner fresh air inlet, for coarse dust certain filter effect is arranged, but for grain dust, poor effect then; (2) this filtering net has only one deck, and unfiltered dust directly enters air trunk after entering fresh wind port easily, thereby sends into the guest room, influences the air quality in the guest room; (3) this filtering installation is not established sediment ejection opening, and is too much because of the grains of sand easily, and causes obstruction to a certain degree, thereby causes that the air interchanger resh air requirement is fewer and feweri, and the guest room negative pressure increases gradually, causes the passenger to produce the situation of tinnitus.
The utility model content
It is effective that the purpose of this utility model provides a kind of anti-dust storm, the anti-dust storm ventilation system that can well protect air quality environment in the guest room.
For achieving the above object, the technical solution adopted in the utility model is: motor train unit trailer air-conditioning is prevented the dust storm ventilation system, comprise the plenum chamber that is positioned at air-conditioning one end, plenum chamber is communicated with the branch air duct that is positioned at the air-conditioning both sides, branch air duct is communicated with by the fresh wind port of setting in light air road and the air-conditioning, and the filtering installation that is used to filter dust storm and water droplet is arranged at the plenum chamber lateral wall.
Described filtering installation comprises entering the anterior baffle that air quickens, be positioned at the middle part rotary fluid and the rear portion air-out body at anterior baffle rear, middle part rotary fluid and rear portion air-out body is used to collect air and it is turned to enters the hollow area that is positioned at air-out body rear, rear portion wherein, the hollow area rear is the multilayer stainless steel cloth, be provided with the filter core that one deck is used to improve dust capaciting ability in the middle of the stainless steel cloth, the hollow area below is provided with sediment ejection opening.
From above-mentioned architectural feature of the present utility model as can be seen, its advantage is:
(1) this ventilation system structure has additional a plenum chamber at the fresh wind port place, is equivalent to the effect of a plenum chamber, helps keeping constant resh air requirement, thereby keeps the stable of guest room internal gas pressure, has avoided the generation of negative pressure to a certain extent;
(2) fresh wind port of the relative air-conditioning of fresh wind port area of this ventilation system structure is bigger, has slowed down the wind speed at fresh wind port place, and the effect by plenum chamber, and air-conditioner fresh air inlet speed is also reduced to some extent, thereby has to a certain degree played the effect that reduces noise;
(3) this ventilation system structure becomes certain angle of inclination to the plenum chamber bottom design, and is provided with sediment ejection opening, makes most of rainwater, and the grains of sand etc. can be discharged outside the car automatically, have reduced the number of times of artificial cleaning.
Description of drawings
The utility model will illustrate by way of compared with accompanying drawings and combined with example:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model filtering installation;
The 4th, light air road 5 is that fresh wind port 6 is that filtering installation 7 is anterior baffles
The 8th, middle part rotary fluid 9 is that rear portion air-out body 10 is hollow area
The 11st, stainless steel cloth 12 is that filter core 13 is sediment ejection openings.
The specific embodiment
The utility model is described further by embodiment below in conjunction with accompanying drawing.
Preferred embodiment
Motor train unit trailer air-conditioning is as shown in Figure 1 prevented the dust storm ventilation system, comprise the plenum chamber 2 that is positioned at air-conditioning 1 one ends, plenum chamber 2 is communicated with the branch air duct 3 that is positioned at air-conditioning 1 both sides, branch air duct 3 is communicated with the fresh wind port 5 of setting in the air-conditioning 1 by light air road 4, and the filtering installation 6 that is used to filter dust storm and water droplet is arranged at plenum chamber 2 lateral walls.
Described filtering installation 6 comprises entering the anterior baffle 7 that air quickens, be positioned at the middle part rotary fluid 8 and the rear portion air-out body 9 at anterior baffle 7 rears, middle part rotary fluid 8 and rear portion air-out body 9 is used to collect air and it is turned to enters the hollow area 10 that is positioned at rear portion air-out body 9 rears wherein, hollow area 10 rears are multilayer stainless steel cloth 11, be provided with the filter core 12 that one deck is used to improve dust capaciting ability in the middle of the stainless steel cloth 11, hollow area 10 belows are provided with sediment ejection opening 13.
