Abstract
The utility model relates to an air purifier, in particular to an air purifying device for a waste pneumatic transport system. The device comprises an air inlet, an air outlet, a housing and activated charcoal filters. The housing is a rectangular cylinder with an open end. The air outlet is arranged on the bottom of the rectangular cylinder. An air inlet cylinder which is rectangular in cross section is provided with unhindered filter openings at two sides. The air inlet cylinder is provided with a port with the air inlet. The air inlet cylinder is fixedly arranged on the open end of the rectangular cylinder of the housing. The activated charcoal filters are divided into two groups. The two groups of the activated charcoal filters are respectively connected with the unhindered filter openings at the two sides of the air inlet cylinder.

Description
Technical field
The utility model relates to a kind of air purifier, particularly a kind of air cleaning unit that is used for rubbish pneumatic conveying system.
Background technology
Strength pipeline refuse transport system is a kind of modern refuse collection transportation facility: utilize air exhauster to make air-flow, by the underground piping network that lays in advance, the rubbish that is located at ground each dispensing port collection is transported to underground collecting refuse station.Process cyclone separator in the transporting something containerized station, rubbish and air-flow are separated, and rubbish falls the back by the container of compressor reducer indentation sealing, and the container of filling rubbish is promoted to the ground entrucking by lifting device and is sent to treatment plant, whole flow process is default by computer program, and collection process is in full closeding state all the time.And the air that transports rubbish must enter air exhauster through after the air filter dedusting.But, air after the dedusting has serious stink, the smell component that produces under the decomposition of the harmful bacterium of microorganism after the organic matter corruption in this rubbish and come out is very complicated, main is the stench liquids and gases of thing based on sulphur such as ammonia, organic amine, hydrogen sulfide, also contains aliphatic category materials such as a spot of formaldehyde, polyformaldehyde, organic nitrogen, nitrogen oxide, ozone, methyl alcohol, toluene, dimethylbenzene, polycyclic aromatic hydrocarbon, methyl mercaptan and trimethylamine or the like.These unpleasant poisonous and harmful liquid gases are serious harm people's key health not only, and heavy damage peripheral underground environment and air ambient.Therefore, can not in air, discharge through the air after the air filter dedusting, must be through the deodorizing purified treatment.
The method of existing air deodorization has: spray deodorant, photocatalyst, ozone and activated carbon.Obviously, the spray deodorant cost is very high; The photocatalyst deodorizing needs solar radiation, can't use ozone need dispose ozone generator, but ozone concentration be higher than a fixed number value Time, can damage for health in underground use.Unique proper activated carbon that has only, the activated carbon trace toxic gas in can absorbed air is such as ammonia, formaldehyde, benzene class etc.Deodorizing effect Strong.
