Abstract
The invention provides a mechanical ventilating system for removing house dust. Slit air outlets are arranged at two sides or a plurality of sides of a junction of a wall and the ground in the system; the height of each slit can be set in a range of 2-10 mm; a ventilating layer is arranged in the wall; and an air diffuser is arranged on an air supply outlet, and a filter and a mechanical air exchange device are arranged on each air outlet. According to the mechanical ventilating system provided by the invention, considerations are given to the characteristics that large-grain-diameter house dust usually subsides on the ground and small-grain-diameter house dust easily floats in the air, so that the positions and shapes of the air outlets are different from those of a traditional mechanical ventilating system in China. Compared with the traditional mechanical ventilating system, the mechanical ventilating system disclosed by the invention has the advantages of shorter processing time and obvious processing effect in house dust removal effect, and particularly, the processing effect of the particulate matter (PM 2.5) which can be easily inhaled into the lungs is more ideal than that of the traditional mechanical ventilating system.
Description
Technical field
The invention belongs to the architectural environment equipment technical field, relate to a kind of mechanical ventilation system of removing room dirt.
Background technology
Traditional ventilating system exhaust outlet is arranged on ceiling more, because air current composition form and gravitational settling effect cause the bigger room dirt particle of size ratio to be easy at superficial deposit, and children's the health thereby influence is creeped on ground.On the other hand, less the gone into lung particle (PM of size ratio
2.5) be easy to swim in aerial, its air current composition form of traditional ventilating system make this part room dirt particle in the human body respiration territory scope stay, cause health is produced harm.
Summary of the invention
The object of the present invention is to provide a kind of mechanical ventilation system of removing room dirt.
Technical scheme of the present invention:
The air outlet of mechanical ventilation system is identical with traditional air outlet.It is characterized in that at the exhaust outlet that the two sides or the multiaspect setting of wall and ground intersection is slit-shaped, the slit height can be made as the 2-10mm scope, is provided with unsaturated zone in the wall.Air outlet is provided with air diffuser, and exhaust outlet is provided with filter, mechanically ventilated device.
New wind is veered away indoor by air outlet through the mechanically ventilated device, through air diffuser air is scattered, and the sedimentation room dirt particle that size ratio is bigger is sent into unsaturated zone from the exhaust outlet of slit-shaped on the one hand, through filter, fresh air ventilator, discharges outdoor through unsaturated zone.On the other hand, because the air-flow action mode makes less the gone into lung particle (PM of particle diameter
2.5) wait room dirt particle to get into the slit-shaped exhaust outlet with air current composition, discharge outdoor.
During actual the use, can mechanically ventilated device branch be arranged, will blow and air draft separates better effects if.
Can find out that through above handling process the present invention has considered that the bigger room dirt particle of size ratio falls to the characteristics on ground usually, discharge this type of room dirt at the exhaust outlet that the two sides or the multiaspect setting of wall and ground intersection is slit-shaped.On the other hand, the gone into lung particle (PM less to size ratio
2.5) can collect near the ground back with air current composition and remove through the slit-shaped exhaust outlet.This mechanical ventilation system is compared with the tradition ventilation system, handles room dirt time weak point, and treatment effect is obvious, and performance is tested through preliminary, proving effect accord with expectation imagination.
Research proves under 0.5 time/h of rate of ventilation situation, the gone into lung particle (PM of tradition ventilation system after 1 hour
2.5) clearance is 30%, the room dirt clearance of new system is 40%, has improved 10%.Under 2.5 times/h of rate of ventilation situation, the gone into lung particle (PM of tradition ventilation system after 1 hour
2.5) clearance is 72%, the room dirt clearance of new system is 81%, has improved 9%.
Under 2.5 times/h of rate of ventilation situation, when slit height 2mm, the gone into lung particle (PM of new system after 1 hour
2.5) clearance is 78%; When slit height 5mm, the gone into lung particle (PM of new system after 1 hour
2.5) clearance is 81%; When slit height 10mm, the gone into lung particle (PM of new system after 1 hour
2.5) clearance is 79%.The slit height in the 2-10mm scope, the gone into lung particle (PM of new system
2.5) specific efficiency is high mutually with the tradition ventilation system for clearance, and be 78% → 81% → 79% Changing Pattern, so ventilating system of the present invention, its slit height is in the 2-10mm scope.
