Suction and solution continuous integrated type air circulation purification device for hospital and chemical environment

Abstract

The invention discloses a suction and solution continuous integrated type air circulation purification device for hospital and chemical environment. The air circulation purification device comprises an exhaust pipe, an air inlet pipe, a first filter screen, a second filter screen, a first fan, a second fan and a ventilation circuit, wherein one ends of each of the first fan and the second fan areconnected to the ventilation circuit, the ventilation circuit is connected to an indoor space of an application occasion, the ends, facing away from the ventilation circuit, of the first fan and the second fan are separately connected to the exhaust pipe, check valves facing the exhaust pipe are arranged among the first fan, the second fan and the exhaust pipe correspondingly, the ends, facing away from the ventilation circuit, of the first fan and the second fan is further summarized and connected to the air inlet pipe, and check valves facing away from the air inlet pipe is arranged among the first fan, the second fan and the air inlet pipe. The first fan and the second fan are axial flow fans which are adjustable in flow direction.

Description

technical field [0001] The invention relates to the field of air circulation purification devices, in particular to an absorption-desorption continuous integrated air circulation purification device for hospitals and chemical environments. Background technique [0002] Environments such as hospitals and chemical industries often require clean and constant temperature indoor spaces, which have high requirements for air. [0003] In the prior art, the ventilation equipment usually only introduces the outside air into the room and sets a shallow filter screen at the inlet. The dirty air in the room is directly discharged to the outside world. The filter screen keeps accumulating dust during use and needs to be replaced frequently. Or cleaning is very troublesome, and in winter, the indoor heat is directly discharged through the stale air, and the newly entered outside air is of lower temperature, which greatly increases the load of the air conditioner. In summer, the indoor low...

[0003] In the prior art, the ventilation equipment usually only introduces the outside air into the room and sets a shallow filter screen at the inlet. The dirty air in the room is directly discharged to the outside world. The filter screen keeps accumulating dust during use and needs to be replaced frequently. Or cleaning is very troublesome, and in winter, the indoor heat is directly discharged through the stale air, and the newly entered outside air is of lower temperature, which greatly increases the load of the air conditioner. In summer, the indoor low-temperature stale air is exhausted Go, the temperature of the newly incoming outside air is higher, which will also increase the load of the air conditioner
