Description

Anion air purification system with quick dust removal function

Technical Field

The invention discloses a negative ion air purification system with a rapid dust removal function, and belongs to the technical field of air conditioning.

Background

At present, the air pollution is serious and affects the health of human beings, and the Canada environmental sanitation organization points out that: 68% of the diseases of human beings are caused by indoor air pollution, and nearly half of people worldwide are in heavy indoor air pollution, and 1 person dies in every 20 seconds.

The air pollution level in many civil and commercial buildings is extremely high, which is several times to tens of times of outdoor air pollution, and some air pollution even exceeds 100 times, while more than 90% of the time of urban residents is spent indoors.

From the present stage, through comprehensive research, the main indoor and outdoor pollutants are classified into 3 types: (1) inhalable particles: dust, soot, pollen, etc.; (2) microorganisms: bacteria, fungi, viruses, etc.; (3) harmful volatile gas: ammonia, carbon monoxide, formaldehyde, benzene, etc.

The purification modes of the existing air purifier are technically divided into the following types:

firstly, a pure filtering mode, namely, a filter screen is used for purifying air;

two, filter screen filtration mode + anion release to filter screen filtration mode is main, and the anion is for assisting, and the anion production under this mode is realized through high voltage corona mode, and for ordinary anion release technique, the poor stability that its anion produced, concentration is low, and when producing the anion, also can produce a large amount of positive charges.

Third, the realization of this kind of purification, the realization often relies on improving the generating voltage of anion to improve its concentration, but concentration improves the time, can produce the high voltage electrostatic field, forms the accumulation of electric charge, can produce a certain amount of ozone even. This purification mode is single, simple structure, because of the influence of electrostatic interference factor, this purification mode can't combine together with other more superior control system, and powerful static can produce certain harm to the human body.

The third purification mode, namely the electrostatic dust removal technology, can quickly and effectively remove indoor smoke dust, but has single function and low purification efficiency. The principle is that a large amount of negative charges are released by high generation voltage of more than 10000V, and when dust in the air passes through a strong electric field ion channel, the dust particles in the air are attracted by opposite charges to form large particles which are captured and adsorbed by a micropore polymerizer; in the process of ionic charge movement, the electronic structure of the bacteria is changed, so that the activity of the bacteria is inhibited, and the sterilization effect is achieved.

When the negative ion module works, air is ionized, and particularly when the rapid dust removal high-voltage module is combined with the purifier, although the purpose of rapidly removing dust and purifying air is achieved, partial static electricity can be generated and coupled into the machine, however, the partial static electricity not only affects the whole machine system, but also can cause harm to human safety, so that the static electricity can be fundamentally solved only by consuming and releasing the static electricity through the circuit system when the static electricity is eliminated, and the adverse effect on the whole machine system is avoided. The implementation of the electrostatic treatment method of the invention greatly improves the system stability, and the following advantages of the invention are detailed:

firstly, on a driving circuit of an anion module, the power is not simply supplied by 12V, and the driving of the anion module is controlled by an Mos tube after the isolation of an optical coupler; when 12V is used for supplying power to the negative ion module, the module starts to work, and a circuit inside the module generates high voltage, so that air is ionized, a large amount of negative ions are released, but a small part of negative ions are gathered inside a machine, so that not only is the whole machine system affected, but also potential safety hazards are brought to a human body. For this reason, a 'split ground' mode is adopted, namely, the front-end input '310V and ground' of the switching power supply and the '15V and ground' of the rear-end output are separated from '12V and ground' and '5V and ground' by adopting the same reference ground, and the whole switching power supply system does not form the whole closed loop system by adopting the same reference ground; the 12V and the ground, the 5V and the ground are connected in parallel, are respectively connected with a neon bulb and a resistor in series, and are connected with the ground of one 310V of the power supply filtering and rectifying circuit to form a static electricity consumption and circulation loop.

The purpose of 'grounding' is to prevent high-voltage static electricity from being coupled to a switch chip through 'reference grounding' to cause damage of the switch chip, and prevent the high-voltage static electricity from arc discharge on a transformer pin, so that the stability, reliability and safety of the switch power supply are improved, and the stable power supply input of a back end circuit is ensured.

And secondly, a 12V ground and a 5V ground are used as main static electricity consumption and circulation loops, so that a neon bulb and a resistor are respectively connected in series on the 12V ground and the 5V ground, are connected with the 310V ground of one of the power supply filter rectifying circuits, pass through the rectifying circuit and are finally output to a power grid to form the whole loop. Due to the high electrostatic voltage and the low current, most of the electrostatic voltage is consumed after passing through the neon bulb and the resistor, so that the influence on the rear-end power grid does not exist. The influence on the circuit of the whole system is also reduced to the minimum, and the stability of the whole system is ensured.

The selective application of "ground", neon bulb "and" resistance "is the key to the overall system core to handle static electricity.

Fourthly, the method comprises the following steps: a motor drive circuit: the circuit requires high parameter setting precision and strong anti-interference capability.

The DA conversion circuit is an RC low-pass filter circuit, 2-medium low-pass filtering is adopted here, stable analog voltage is achieved, and the stability of the rotating speed of the motor is guaranteed. Because motor drive part voltage is 15V, and motor rotor voltage is 310V, consequently need add the opto-coupler at the control part and keep apart, guarantee the stability of front-end system, on the circuit, use 3 opto-couplers to be used for PWM's control isolation, motor rotational speed feedback pulse signal isolation, can signal isolation when motor voltage respectively.

Fifthly: buzzer drive circuit: the circuit adopts a piezoelectric ceramic buzzer, is driven by matching with different frequencies, and can emit crisp and pleasant ringing. The method comprises the following specific steps: the driving voltage of the buzzer is 12V, the driving voltage and the system control voltage are not the same reference ground, and an optical coupler is required to be added for isolation, so that the stability of the front end is ensured. The CPU adopts 2-way Timer to output different frequency waveforms to combine into a section of ring, mainly including (power-on ring, power-off ring, key ring, module start working ring, module stop working ring).

Sixthly, the method comprises the following steps: air quality detection circuit: the circuit adopts a dust sensor, and has high sensitivity and long service life. The method comprises the following specific steps: the sensor adopts an optical principle, utilizes the relation between the luminous body and the receiving body, when the luminous body works, the size of particles carried by air is different, so that the light interruption effect of the luminous body is different, the brightness received by the receiving body is different, different voltage values are generated, the CPU judges the control quality according to the voltage values, and in order to prolong the service life of the sensor, the luminous body is required to be closed when the air quality is not detected.
