201 and second center-aisle 202.
It can be moveable bulkhead that first removable isolated element 70 and second, which may move isolated element 80, be moved into
Centre position, passage can be completely cut off；It is moved into above housing, passage can be merged.
Feedback pipe 90 is set after valve 40, and it receives the air by valve 40；In the side of second entrance passage 102
Feedback channel opening 91 is set, and feedback pipe 90 is connected with feedback channel opening 91, the air that valve 40 is flowed out, can pass through
Feedback channel opening 91 carries out second entrance passage 102.
Second entrance passage 102 sets rotation valve 92, and it can close the air intake for second entrance passage 102
Or feedback channel opening 91.When rotation valve 92 rotates to vertical position, it is together with the first removable isolated element 70
The air for completely cutting off second entrance passage 102 is flowed into, and now feedback channel opening 91 is opened；When rotation valve 92 rotates to horizontal position
When putting, feedback channel opening 91 is closed, and second entrance passage 102 can carry out air inflow.
The testing result of controller reception air borne sensor 50, the dust concentration in intake air, control valve 40,
First removable isolated element 70, second may move isolated element 80, the switch for rotating valve 92 and motion.
Specifically, when the dust concentration that air borne sensor 50 is detected in air is more than and sets threshold value, referring to Fig. 2, if
Put rotation valve 92 and arrive vertical position, open feedback channel opening 91, the air intake of closing second entrance passage 102；It is mobile
First removable isolated element 70 and second may move isolated element 80, form first entrance passage 101, second entrance passage
102nd, the first center-aisle 201 and the second center-aisle 202；Open valve 40.
First entrance passage 101, the top of deduster 10, the first center-aisle 201 and valve 40, form the first air
Purification channel；Second entrance passage 102, the bottom of deduster 10, the second center-aisle 202 and catalyst filter core 30, formed
Second purification of air passage, wherein reactant generator 20 are located in the second purification of air passage.Can be in the first purification of air
Passage and the second purification of air passage, set the first extraction fan and the second extraction fan, for driving the stream of air respectively
It is dynamic.
Air cleaning unit in this condition when, air passes sequentially through the first purification of air passage, feedback pipe and
After the purification of two purification of air passages, return in environment.
When the dust concentration that air borne sensor 50 is detected in air, which is less than, sets threshold value, referring to Fig. 1, rotation is set to live
Door 92 is to horizontal level so as to closing feedback channel opening 91；Mobile first removable isolated element 70, merges first entrance and leads to
