Abstract
The invention discloses an air inlet scoop of a noiseless-cabinet diesel generating set. The air inlet scoop comprises a noiseless cabinet. Sound absorption cotton is arranged on each of the front side wall and the rear side wall of the noiseless cabinet. A plurality of air inlets are arranged on the front side wall of the noiseless cabinet along the height direction. Protecting nets are arranged outside the air inlets. A plurality of air outlets are arranged on the rear side wall of the noiseless cabinet. Waterproof plates with 45-degree inclination angles are connected between the front side wall and the rear side wall both below the air inlets. Air deflectors are connected to the front side wall above the air inlets and are parallel to the waterproof plates. The air inlets and the air outlets are positioned on the upper sides and the lower sides of the air deflectors respectively. The air inlet scoop has good noise reduction effect, and noise is effectively attenuated; the air inlet scoop has good protection effect, protection grade is superior to IP44, and the air inlet scoop can be used outdoors.
Description
Technical field
The present invention relates to protective equipment field, be specially silencing case diesel generating set inlet scoop.
Background technique
Along with social progress, security standby power supply has become an indispensable part in life.Petroleum system, mining industry, airport, real estate, the energy, harbour, railway, finance, integrated mill, military project, hotel, municipal key project, hospital, apartment house fire-fighting etc. all can be used diesel generating set and be done standby power supply or primary power cource.But there is the drawback that noise is large in diesel generating set, and more and more being subject to people's attention of noise pollution, the most effective solution is to build diesel generating set machine room.But there is the drawbacks such as long in time limit, expense is high, noise reduction is not obvious in diesel generating set machine room, for solving these deficiencies, a kind of novel product---silencing case diesel generating set has been born.Present 90% above user requires to buy silencing case diesel generating set, and 95% above diesel generating set producer is all producing silencing case diesel generating set, but the noise reduction of silencing case unit, protection are not very desirable, and client need to do secondary protection and noise reduction.
Summary of the invention
For the problems referred to above, the invention provides a kind of silencing case diesel generating set inlet scoop, it has good noise reduction, has effectively weakened noise; Have good protection effect, security level is better than IP44, can use out of doors.
Technological scheme of the present invention is:
A kind of silencing case diesel generating set inlet scoop, include silencing case, on silencing case front panel, rear sidewall, be respectively equipped with acoustical cotton, silencing case front panel has several intake grills along short transverse, and intake grill is provided with protective net outward, and rear sidewall has several exhaust outlets, between the front panel of intake grill below and rear sidewall, be connected with 45 ° of splash guards, the front panel of intake grill top is connected with wind deflector, and wind deflector and splash guard be arranged in parallel, and intake grill, exhaust outlet are positioned at the upper and lower of wind deflector.
Described splash guard bottom has water-leaking hole.
Described exhaust outlet is provided with filter screen outward.
Wind scoop of the present invention has an air flow passage vertically upward, and this passage capable of being prevents that water droplet is inhaled into silencing case inside.Concrete principle is: under 20 ° of C, the surface tension of water is 72.75 × 10-3 Nm-1, the speed of air and the relation formula of pressure: P=ρ V2=1.3 × V2 (Pa of unit), the density of water is 1g/cm3.Silencing case diesel generating set intake grill wind speed is generally 3～10m/s, learn that thus the tension force of water molecule is much smaller than the pressure of Air Flow generation, the pressure that Air Flow produces is less than the gravity of water molecule self, and hence one can see that: water droplet is impossible vertically be inhaled into silencing case inside.
Wind scoop air flow passage is through 2 45 ° of break-ins, 3 90 ° of break-ins.The feature of this structure is the air channel that has lengthened intake grill, effectively reduces intake grill noise.
Wind scoop has multiple independent intake grills.The feature of this structure is effectively to utilize space, is convenient to integral installation.
Described acoustical cotton 4 and 5 is lamination coating, and attraction coefficient is greater than 0.8, can reduce the noise of import.
Water-leaking hole 6 is arranged at described wind deflector 3 bottoms, so that equipment spills after the water vapour that stops cold and hot conversion generation in start process condenses.
Protective net 1 perforate size is 10mm × 70mm, can prevent the invasion of large-sized solid particulate matter; Splash guard 2 is parallel with wind deflector 3, and protective net 1 angle is 45 °, and air changes direction immediately through protective net, is less than 10mm solid particulate matter and flows out along splash guard 2 after collision; Filter screen is that 100 order metal filter screens are made, and structural strength is good, is convenient to change.
Adopt after the present invention, effectively solve protection and the noise reduction problem of silencing case diesel generating set in static and running state, wind scoop security level is better than IP44.Noise source is sent after noise, in propagation process of sound wave, weakens through the repeatedly bounce-back of steel plate and lamination coating, is absorbed by lamination coating, has effectively lowered noise, has prevented noise pollution.Cooling-air enters through protective net 1, change direction along splash guard 2 and wind deflector 3 upwards through 2 45 ° of break-ins, 3 90 ° of break-ins enter silencing case inside; In air break-in process, airborne water droplet and small solid particulate matter collide through splash guard 2 and wind deflector 3, because gravity is greater than suffered air pressure, vertically fall, and flow out along splash guard 2; Filter screen is that 100 order metal filter screens are made, and further filters solid dust.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the J-J sectional view of Fig. 1.
Embodiment
Referring to accompanying drawing, a kind of silencing case diesel generating set inlet scoop, include silencing case, silencing case front panel, on rear sidewall, be respectively equipped with acoustical cotton 4, 5, silencing case front panel has several intake grills along short transverse, intake grill is provided with protective net 1 outward, rear sidewall has several exhaust outlets, exhaust outlet is provided with filter screen outward, between the front panel of intake grill below and rear sidewall, be connected with 45 ° of splash guards, the front panel of intake grill top is connected with wind deflector, wind deflector 3 be arranged in parallel with splash guard 2, intake grill, exhaust outlet is positioned at the upper and lower of wind deflector 3, splash guard 2 bottoms have water-leaking hole 6.
Diesel generating set when operation cooling-air enters through protective net 1, change direction along splash guard 2 and wind deflector 3 upwards through 2 45 ° of break-ins, 3 90 ° of break-ins enter silencing case inside; In air break-in process, airborne water droplet and small solid particulate matter collide through splash guard 2 and wind deflector 3, because gravity is greater than suffered air pressure, vertically fall, and flow out along splash guard 2; Filter screen 6 is that 100 order metal filter screens are made, and further filters solid dust; Water-leaking hole 3-1 is arranged at wind deflector 3 bottoms, and equipment spills after the water vapour that stops cold and hot conversion generation in start process condenses; Acoustical cotton 4 and 5 absorbs noise in noise transmission process.
