Fig. 2 be the room air of the utility model detect and cleaning system in the sketch map of concrete structure of detection and control module.
The specific embodiment
Below, with the embodiment of accompanying drawings the utility model.
Fig. 1 is the room air detection of the utility model and the structural representation of cleaning system.As shown in Figure 1, this room air detects and cleaning system comprises air intake grid 11; Micronic filter 12, its air inlet is connected with the air outlet of said air intake grid 11; Cold catalyst filter 13, its air inlet is connected with the air outlet of said micronic filter 12; Blower fan 14, its air inlet is connected with the air outlet of said cold catalyst filter 13; A plurality of air outlet grille 17-1,17-2,17-3, their air inlet is connected with the air outlet of said blower fan 14; Detect and control module 15, be connected to said micronic filter 12, cold catalyst filter 13 and blower fan 14; And LCD display 16, be connected to said detection and control module 15.
Said air intake grid 11 is equipped with primary filter net (not shown), is used to filter out the bigger micronic dust of particle diameter.Said micronic filter 12 is used to filter out the less micronic dust of particle diameter.
Cold catalyst filter 13 is used to absorb and decompose the airborne organic gas of seeing off from the air outlet of said micronic filter 12, for example pernicious gases such as formaldehyde, benzene, xylenes, toluene, TVOC.Cold catalyst can be in the following catalytic reaction of normal temperature condition, and making at normal temperatures and pressures multiplely has flavor gas to resolve into harmless tasteless substance, changes chemisorbed into by simple physical absorption; Decompose while adsorbing, dispel pernicious gases such as formaldehyde, benzene, xylenes, toluene, TVOC, generate water and carbon dioxide; In catalytic reaction process; Itself does not participate in reaction directly cold catalyst, and the cold catalyst in reaction back does not change does not lose long-term role.Cold catalyst itself is nontoxic, non-corrosiveness, do not burn, and reaction product is water and carbon dioxide, does not produce secondary pollution, has prolonged the service life of sorbing material greatly.The principle of cold catalyst is a catalytic oxidation, and the catalyst composition plays the medium effect in this process, and its composition can not change, and can need not any processing and long-term the use.Cartalytic decomposition effect does not need ultraviolet ray, high temperature, high pressure.Reach more than 5 ℃ at temperature, humidity reaches under the condition more than 40%, and the effect of cold catalyst catalytic decomposition pernicious gas just can reach perfect condition.
Blower fan 14 be used for the air after handling through said cold catalyst filter 13 deliver to be installed in the room everywhere/each air outlet grille 17-1 at each place, room, 17-2,17-3, thereby cleaned air passes is delivered to indoor the most at last.
Said detection and control module 15 can detect the quality of room air, and testing result is presented on the LCD display 16.Said detection and control module 15 are controlled the On/Off of micronic filter 12 and cold catalyst filter 13 also according to above-mentioned testing result.In addition, said detection and control module 15 can be controlled the On/Off of blower fan 14 according to the control (input instruction) of user (operator) through LCD display 16.
Fig. 2 illustrates room air detection and the detection in the cleaning system and the concrete structure of control module 15 of the utility model.As shown in Figure 2, micronic dust sensor 21, organic gas sensor 22 and differential pressure pickup 23 are connected to a signal amplifier 24.This signal amplifier 24 is connected to an A/D converter 25.This A/D converter 25 is connected to a CPU 26.This CPU 26 is connected with cold catalyst filter 13 with micronic filter 12 through data/address bus, and also is connected to said LCD display 16 in addition.
Said micronic dust sensor 21 is used for the micronic dust concentration of room air is detected.For example can adopt homemade realizations such as GCG1000 type sensor of dust concentration.
Said organic gas sensor 22 is used for the organic gas concentration of room air is detected.This organic gas sensor 22 for example can adopt the MQ135 gas sensor.MQ135 is a kind of high-precision semiconductor gas sensor, and employed gas sensitive is the tin ash that electrical conductivity is lower in clean air (Sn02).When having organic gas such as formaldehyde in the sensor environment of living in, the electrical conductivity of sensor increases with the increase of organic gas concentration in the air.The variation of this electrical conductivity is converted into and the corresponding output signal of organic concentration.
Under the control of CPU 26, also will be presented on the LCD display 16 by said micronic dust sensor 21 and the IAQ that said organic gas sensor 22 measures.
Said differential pressure pickup 23 is installed in the said micronic filter 12, is used for the air pressure difference of the filter screen both sides in this differential pressure pickup 23 is measured.After this air pressure difference was lower than predetermined value, CPU26 judges should change filter screen, and showed repair message at said LCD display 16.
The room air detection of the utility model and the processing procedure of cleaning system are following.
Air gets in this room air detection and the cleaning system via said air intake grid 11, and falls bigger micronic dust by said primary filter net filtration.Then, the air behind the primary filter gets into micronic filter 12 and carries out secondary filter, and the air after filtering through this micronic filter 12 has not contained the micronic dust of particle diameter more than 0.3 μ m.Subsequently, air gets into cold catalyst filter 13, thereby removes the organic pernicious gas (for example, formaldehyde, benzene, xylenes, toluene, TVOC etc.) that wherein comprises.At last, return to indoor via each air outlet grille 17-1,17-2,17-3 cleaned air passes by blower fan 14.
The measured value of said micronic dust sensor 21, organic gas sensor 22 and differential pressure pickup 23 amplifies and after the A/D converter conversion, is admitted to CPU 26 through signal amplifier 24.During micronic dust concentration National standard (or a predetermined value) in judging room air, CPU 26 output signals to be closing said micronic filter 12, otherwise, then open this micronic filter 12.In like manner, during organic gas concentration National standard (or a predetermined value) in judging room air, CPU 26 output signals to be closing said cold catalyst filter, otherwise, then open this cold catalyst filter.In addition, said detection and control module 15 can be controlled the On/Off of blower fan 14 according to the control (input instruction) of user (operator) through LCD display 16.After the air pressure difference of being measured by said differential pressure pickup 23 was lower than predetermined value, CPU 26 judged the filter screen that should change in the said micronic filter 12.
Utilize the room air of the utility model to detect and cleaning system, can not only detect, can also control different filters respectively according to testing result to the micronic dust concentration in the room air and harmful organic gas concentration.
It will be understood by those skilled in the art that above-mentioned explanation and instance only are exemplary, and be not the scope that is used to limit the utility model.Under the degree of the scope that does not exceed the utility model that limits like claims, can carry out various improvement to the utility model.For example, the number of said air outlet grille is not restricted to 3.
