Description
Technical field
The utility model relates to air purification processing equipment technical field, relates in particular to a kind of intelligent online and detects particle variable air volume system.
Background technology
Traditional medicine industry A, B level toilet all adopts and determines air quantity air-supply, and fixed or variable air rate returns air draft.According to the tenth regulation of the aseptic appendix of new edition GMP, clearly proposing need to be to A, and B detects toilet online, guarantees aseptic environment for use.If these two parts are combined, can realize the change of medical toilet purification style, by traditional " constant air volume system ", to " variable air rate " system change, by traditional " estimating empirical ", to " required design ", changed.Conventionally everybody estimates according to some empirical data the tradition B of toilet rank, think as long as room rate of ventilation reaches a certain numerical value (such as 40-60 time/hour, even higher), whether room is exactly the B level environment that we need, utilize on-line detecting system auxiliary detection room environment correct simultaneously.But run counter to so energy-conservation principle, because different equipment, different production technologies, different places, different operating personnel, different operations, different material Dou Huidui toilets produces dirt and exerts an influence, cannot treat different things as the same, all a unified numerical value, causes the waste of electric energy.Equally, the C stipulating in new edition GMP, D rank also can be suitable for mentioned above principle, and due to C, D rank and requirement are than A, and B level is low, just no longer describes here.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of intelligent online and detects particle variable air volume system, described variable air volume system detects in real time the actual value of particle and according to the value of particle, controls the size of air quantity, rate of ventilation be can reduce, thereby the consumption of electric energy, energy-conserving and environment-protective reduced.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of intelligent online detects particle variable air volume system, it is characterized in that comprising PLC controller, detection of particles sensor, air-supply variable air rate valve, Temperature Humidity Sensor, water valve, pressure sensor, return air variable air rate valve, air flow sensor and frequency converter, described detection of particles sensor, Temperature Humidity Sensor, pressure sensor is connected with the input of PLC controller respectively with air flow sensor, described air-supply variable air rate valve, water valve, return air variable air rate valve is connected and is controlled by described PLC controller with frequency converter with the output of PLC controller.
Preferably, described PLC controller uses the S7-300 type PLC controller of Siemens Company.
Preferably, described pressure sensor uses CPE110 type pressure sensor.
Preferably, described air flow sensor is used the CP300 type air flow sensor of KIMO company.
Preferably, described detection of particles sensor uses Metone4815 type detection of particles sensor.
The beneficial effect that adopts technique scheme to produce is: described system collects the true dust-producing amount in room by detection of particles sensor, by data wire, upload to PLC controller, then PLC controller is through processing the aperture of controlling air-supply variable air rate valve by data wire, adjust room air output, because causing room pressure, air-supply changes simultaneously, PLC controller obtains room pressure value by pressure sensor, controls the aperture of return air variable air rate valve, guarantees room pressure stability.Through adjusting, the indexs such as room cleanliness factor, pressure all meet after toilet's requirement, and PLC controller gathers air quantity information by the air flow sensor on supervisor, feeds back to PLC controller, and PLC controller is controlled the frequency converter of air-conditioning box and adjusted to suitable air quantity.Described variable air volume system detects in real time the actual value of particle and according to the value of particle, controls the size of air quantity, can reduce rate of ventilation, thereby reduces the consumption of electric energy, energy-conserving and environment-protective.
