The specific embodiment

In Fig. 1,2, cleaner air package comprises air-supply room 18, air filter housing 2, pressure fan 4, humidification cyclic water tank 8.Be provided with airstrainer 1 in air-supply bottom, 18 top, room, air-supply is provided with air filter housing 2 in the room 18.Top in air filter housing 2 is provided with annular hydraulic spray nozzle pipe 19, and several hydraulic spray nozzles 17 are housed on its pipe, and the spraying of nozzle 17 mouth downs, its effect are that the air in the filter mantle 2 is done further dedusting and added wet process.Establish a circulation upper hose 3 on the blast tube 19.Bottom in air-supply room 18 is provided with boss 5, and pressure fan 4 is housed on the boss 5, and covers and go up air-supply hood 16, and the effect of its cover is that the water that prevents spray nozzle 17 sprayings is fallen on the pressure fan 4.Form sewer 6 around air filter housing 2 bottoms and between boss 5 bottoms, its effect is the well-regulated sewer 6 that flows to of water that makes spray nozzle 17 sprayings.

Side at pressure fan 4 is provided with breather pipe I ₁₅, breather pipe I ₁₅On be respectively equipped with warm-air pipe 12 and cool air hose 9.Air heater 14 and HACV Hot Air Control Valve 13 are housed on warm-air pipe 12, and its effect is to add hot-air, uses at cold day.On cool air hose 9 cold air control valve 10 is housed, its effect is coldization, humidifying air, uses in hot day.Breather pipe II ₁₁Be connected with the three-dimensional breather pipe 21 of lazaretto ward porous.

Outside in air-supply room 18 is provided with humidification cyclic water tank 8, and pressure pump 7 is housed in the humidification cyclic water tank 8, and pressure pump 7 connects circulation upper hose 3.One side of humidification cyclic water tank 8 is provided with circulation downcomer 20, is connected with sewer 6.

Breather pipe 21 enters ward 28, ventilation device adopts double-layer porous three-

dimensional snorkel

24,25,26,27 in the ward, uniform several pores on its snorkel, these

structure bottom snorkel

25,27 close proximity to grounds are layed in around the corner, and the pore of

snorkel

25,27 is up;

Upper strata snorkel

24,26 pastes wall around the wall and sets up for about 2.2 meters apart from ground, and the pore on the

snorkel

24,26 is towards femerell;

Bottom snorkel

25,27 and

upper strata snorkel

24,26 are connected up and down by four vertical tubes 22 being close to the corner, do not establish pore on the vertical snorkel 22.Under the aerodynamic flow forces effect, the stable state when air leaves standstill in the room is thoroughly broken, and air flows in order in the formation room.The system of a relative closure is arranged in the ward simultaneously, though window is arranged, does not advocate arbitrarily to window at ordinary times ventilation, only establishes a ventilating opening at the place, roof and directly communicates with the external world.Lazaretto ward is arranged to the taper roof, is beneficial to the discharging of indoor gas.The ventilating opening place is provided with high-temperature electric heat air disinfection device 23, and its profile is columniform fire-resistant tube, and the nozzle top is provided with rainhat 30, in the tube electrical bar 29 is housed, and length is 1m, and power is 1KW, and all gases of being discharged by the ward are carried out high-temperature disinfection treatment.

The working procedure that closed room is injected cleaner air package is such:

Outside air enters air-supply room 18 through airstrainer 1 preliminary the filtration, filters once more through air filter housing 2 to enter in the cover.Start pressure pump 7, the water that pumps enters annular hydraulic spray nozzle pipe 19 by circulation upper hose 3, make the hydraulic spray nozzle 17 on the annular hydraulic spray nozzle pipe 19 that covers the inner top setting, spraying down simultaneously, air in the filter mantle 2 is done further dedusting and added wet process, spray water flows into sewer 6, flows into cyclic water tank 8 by circulation downcomer 20.Air after the processing enters pressure fan 4, sends into breather pipe I by pressure fan 4 pressurizations ₁₅Along with the variation of weather, hot day breather pipe I ₁₅Air can open cold air control valve 10 and enter breather pipe II by closing HACV Hot Air Control Valve 13 ₁₁Cold day breather pipe I ₁₅Air can close cold air control valve 10, by air heater 14, make air heat, open HACV Hot Air Control Valve 13 then, make hot-air enter breather pipe II ₁₁Air is admitted to breather pipe 21, enters ward 28, and this moment, air was supplied gas by

bottom snorkel

25,27 symmetries, and

snorkel

24,26 symmetries in upper strata are supplied gas, and the air in the ward is flowed in order.The gas that the ward is discharged carries out high-temperature disinfection treatment by high-temperature electric heat air disinfection device 23, has realized lazaretto ward air " zero disposal of pollutants ".
