Air distribution wrapping the diesel generator set is formed, ventilation cooling efficiency can be improved greatly, volume of an air inlet system and an air outlet system is reduced, and project construction cost is reduced.
Description
Technical field:
The present invention relates to a kind of ventilation cooling system, particularly relate to a kind of underground diesel electric power plant ventilation cooling system.
Background technique:
Will distribute a large amount of heats during the diesel generating set generating, in underground diesel electric power plant, these heats are to take away through the ventilation cooling system in power station.Ventilation cooling system is made up of air inlet system and exhaust system usually, and air inlet system is made up of air intake machine and air intake pipe again, and exhaust system is made up of air bells exhauster and exhaust duct again.The underground power station generally is a long and narrow space; Diesel generator is positioned at the middle part, power station; Air intake pipe and exhaust duct are arranged in longer body of wall top, generator both sides; Exhaust outlet on the air intake pipe is seen low temperature, clean air off from a side, absorbs heat and pollutant through diesel generator, and then the exhaust port from the exhaust duct of opposite side is discharged outdoor.The air output of this system form and exhaust air rate are all bigger, and this makes air inlet system and exhaust system volume all huger.For underground engineering; Huge blower fan and the airduct cost height of being not only itself of air inlet system and exhaust system; And because it will be from the underground ground of leading to; Also be necessary for it and excavate the civil engineering passage, the cost of civil engineering passage is much larger than the cost of airduct and blower fan, so the cost of underground power station ventilation cooling system is far above ground surface works.For reconstruction project, increasing generated output just must corresponding expansion ventilation cooling system, will enlarge the civil engineering passage of ventilation cooling system like this, and this makes the engineering construction difficulty big and cost is very high.To this problem, there is not solution with strong points at present.
Summary of the invention:
The purpose of this invention is to provide a kind of underground diesel electric power plant ventilation cooling system, it can make, and underground diesel electric power plant ventilation cooling system volume reduces, cost reduces.
A kind of underground diesel electric power plant ventilation cooling system; Comprise air intake machine, air intake pipe, air bells exhauster, exhaust duct; Also comprise devaporizer; Said devaporizer is positioned on the air intake pipe, and the exhaust outlet of said air intake pipe is positioned at around the bottom of diesel generating set, and the exhaust port of said exhaust duct is positioned at the top of diesel generating set.
When underground diesel electric power plant ventilation cooling system is worked; Open air intake machine and air bells exhauster; The air that comes from ground gets into air intake pipe, then gets into devaporizer, is evaporating cold go humidity of the air increase in the device, temperature reduction; Then through the air intake machine, the exhaust outlet of the air intake pipe around the bottom that is located at diesel generating set is upwards seen off at last.Because the diesel generating set surface temperature is very high, by heating rapidly, temperature raises the air of seeing off in uphill process, humidity reduces.Because the exhaust port of exhaust duct is positioned at the top of diesel generating set,,, be discharged to ground space at last through exhaust duct and air bells exhauster so the air-flow that rises is sucked rapidly by the exhaust port of exhaust duct.Here want lay special stress on a bit; Humidity of the air through devaporizer is big, maybe be near saturation state, after upwards seeing off from the exhaust outlet of air intake pipe; Siphoned away by the exhaust port of exhaust duct rapidly, so it is difficult to be diffused near the space in addition of diesel generating set.If spread out, because the underground power station wall surface temperature is lower, these will form the dewfall phenomenon at wall near saturated air, and this shortcoming engineering is unacceptable.The technology of the present invention's proposition can be avoided the dewfall phenomenon conversely speaking,, is exactly of the present invention one big advantage.
In present underground diesel electric power plant ventilation cooling system; The heat of diesel generating set is to be dispersed into the space, power station earlier, is then taken away by ventilation cooling system, so efficient is low again; Air output that needs and exhaust air rate are just big, and the temperature in whole space, power station is all higher.Ventilation cooling system utilization air-supply that the present invention proposes and air draft have formed the air-flow of parcel diesel generating set; The heat of diesel generating set is not diffused into the space, power station; But directly taken away; So its ventilation cooling effectiveness is high, the air output and the exhaust air rate that need like this just can significantly reduce.And; Because outside the heat of diesel generating set is not dispersed near the diesel generating set; So the temperature of its complementary space of power station is still lower; And the movable space of operator just, this space, we are lower in order to guarantee this space temperature exactly to a great extent to the cooling of ventilating of underground diesel electric power plant.
The invention has the advantages that: compared with prior art because of the present inventionly advance, exhaust air rate can significantly reduce, and correspondingly advances, the exhaust system volume just will reduce, volume reduces its cost and has reduced with regard to corresponding.
Description of drawings:
Fig. 1 is the system schematic of the underground diesel electric power plant ventilation cooling system of the present invention.
Embodiment:
As shown in Figure 1; A kind of underground diesel electric power plant ventilation cooling system; Comprise air intake machine 1, air intake pipe 2, air bells exhauster 3, exhaust duct 4, also comprise devaporizer 5, said devaporizer 5 is positioned on the air intake pipe 2; The exhaust outlet 7 of air intake pipe 2 is positioned at around the bottom of diesel generating set, and the exhaust port 6 of exhaust duct 4 is positioned at the top of diesel generating set.Here explanation a bit, and is more succinct in order to make diagram, the diesel generating set that do not draw among Fig. 1, the just position of with dashed lines square frame 8 signal diesel generating sets.
When underground diesel electric power plant ventilation cooling system is worked; Open air intake machine 1 and air bells exhauster 3; The air that comes from ground gets into air intake pipe 2, then gets into devaporizer 5, is evaporating cold go humidity of the air increase in the device 5, temperature reduction; Then through air intake machine 1, the exhaust outlet 7 of the air intake pipe around the bottom that is located at diesel generating set is upwards seen off at last.Because the diesel generating set surface temperature is very high, by heating rapidly, temperature raises the air of seeing off in uphill process, humidity reduces.Because the exhaust port 6 of exhaust duct is positioned at the top of diesel generating set,,, be discharged to ground space at last through exhaust duct 6 and air bells exhauster 3 so the air-flow that rises is sucked rapidly by the exhaust port 6 of exhaust duct.Here want lay special stress on a bit; Humidity of the air through devaporizer 5 is big; Possibly after upwards seeing off, siphoned away by the exhaust port 6 of exhaust duct rapidly near saturation state from the exhaust outlet 7 of air intake pipe; So it is difficult to be diffused near the space in addition of diesel generating set, has avoided the dewfall phenomenon like this.
