In present embodiment, clarifier Detection & Controling work comprises the following steps:
A1: before purification work starts, the detection carrying out screen pack (2) more changes jobs, and the detection replacing work of above-mentioned screen pack (2) comprises the following steps:
S1: controller 3 controls the first protection box 23, second and protects box 25, the 3rd protection box 28 and the 4th protection box 30, its automatic opening door is opened, control unlatching first generating laser 24, first laser pickoff 26, second generating laser 29 and the second laser pickoff 27, dirt detection is carried out to the screen pack unit 21 being in first area 18 and the 3rd region 20;
S2: controller 3 gets the information that the first laser pickoff 26 does not receive the first generating laser 24 Emission Lasers, and controller 3 sends instruction and controls the first driving mechanism action, and drive roll 13 rotates and is wound around 2 (L
1+ L
2) long screen pack 2; Controller 3 only gets the information that the second laser pickoff 27 does not receive the laser that the second generating laser 29 is launched, and controller 3 sends instruction and controls the first driving mechanism action, and drive roll 13 rotates and is wound around (L
1+ L
2) long screen pack 2;
S3: controller 3 controls the first protection box 23, second and protects box 25, the 3rd protection box 28 and the 4th protection box 30; its automatic opening door is closed, and controls closedown first generating laser 24, first laser pickoff 26, second generating laser 29 and the second laser pickoff 27.
A2: after purification work starts, controller 3 controls the first air quality detector 33, second air quality detector 34 and processor 35 works, processor 35 carries out analysis contrast to the first air quality detector 33 and the second air quality detector 34 detected parameters, and judge according to the PM2.5 value higher control air quality detected this principle poorer, if controller 3 obtains by processor 35 information that air quality that second air quality detector 34 detects is inferior to the air quality that the first air quality detector 33 detects, then controller 3 controls end-of-job, if controller 3 obtains by processor 35 information that air quality that second air quality detector 34 detects is better than the air quality that the first air quality detector 33 detects, then send instruction control clarifier to restart, and before purification work starts, the detection carrying out screen pack 2 more changes jobs, after purification work starts, controller 3 controls the first air quality detector 33, second air quality detector 34 and processor 35 work, processor 35 carries out analysis contrast to the first air quality detector 33 and the second air quality detector 34 detected parameters, if controller 3 obtains by processor 35 information that air quality that second air quality detector 34 detects is better than the air quality that the first air quality detector 33 detects, then send the closedown of instruction control clarifier to quit work.
Before purification work starts, be first detected filter screen unit 21 the need of replacing, according to step S1-S3, ensure that screen pack unit 21 normally works.
When screen pack unit 21 upper cover of first area 18 has expired dirt, drive roll 13 has rotated and has been wound around 2 (L
1+ L
2) long screen pack 2, make first area 18 and the 3rd region 20 be replaced with clean screen pack unit 21; When be only screen pack unit 21 upper cover being in the 3rd region 20 expired dirt time, drive roll 13 rotates and is wound around (L
1+ L
2) long screen pack 2, make first area 18 be replaced with clean screen pack unit 21, and the 3rd region 20 adopts last round of first area 18 place to be stamped part dirt but also do not cover full screen pack unit 21, continue to use.The air introduced by the first fan 6 is after filtering through the screen pack unit 21 in the 3rd region 20, impurity content reduces, therefore, in most cases, after use after a while, the amount of contaminants be on the screen pack unit 21 in the 3rd region 20 will more than the dirt be on the screen pack unit 21 of first area 18, therefore, in most cases, screen pack unit 21 after first area 18 uses, equal can continuation on the 3rd position uses a period of time, thus raising filter effect, extend the service life of screen pack, realize the function automatically changing screen pack.
According to steps A 1-A2; once the air quality after purification is poorer than indoor air quality; start to detect adjustment screen pack 2; it is made to be in normal operating condition, now, if the air quality after purification is still poor than IAQ; then can be judged as other faults; need maintenance down, avoid user in unwitting situation, pass into too much even worse air because of clarifier fault to indoor.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
