Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1 and the modular structure that Fig. 2, Fig. 1 are a kind of specific embodiment provided by the utility model is illustrated
Figure, Fig. 2 is that (arrow direction is in figure for a kind of concrete structure schematic diagram of specific embodiment provided by the utility model
Air current flow direction).
In a kind of specific embodiment provided by the utility model, the air filtering system on-Line Monitor Device of boiler
Mainly include first sensor 2, second sensor 3 and monitoring modular 4.
Wherein, first sensor 2 is arranged on the side of air filtering core 1, mainly for detection of from the inlet side of air filtering core 1
The air pressure of entrance, i.e. aspiration pressure.And second sensor 3 is arranged on the opposite side of air filtering core 1, mainly for detection of from
The air pressure of the air side outflow of air filtering core 1, that is, go out wind pressure.
Need to know, when the behaviour in service of air filtering core 1 is normal, aspiration pressure is essentially equal with wind pressure is gone out in theory
, though exist small difference can also be considered as it is identical, but when the behaviour in service of air filtering core 1 is abnormal, such as air
When the impurity adhered on filter core 1 is more, the flow rate of air filtering core 1 is low, now goes out wind pressure less than aspiration pressure, or even in sky
When the impurity that filter element 1 is attached to is blocked, it is zero to go out wind pressure.
Monitoring modular 4 is connected with first sensor 2 and the signal of second sensor 3 simultaneously, is mainly used in receiving the first sensing
Blast detected value transmitted by device 2 and second sensor 3, and the difference of the detected value transmitted by both exceedes predetermined threshold value
When staff etc. is warned.
In this way, air filtering system on-Line Monitor Device provided by the utility model, by first sensor 2 and second
Sensor 3 detects the blast of the both sides of air filtering core 1 respectively, then by the detection data of both real-time monitorings of monitoring modular 4, works as sky
When the blast difference of the both sides of filter element 1 exceedes predetermined threshold value, staff is warned so that staff knows pot in time
The behaviour in service of the air filtering system on stove, investigates hidden danger as early as possible, it is to avoid cause boiler to damage, improve production efficiency.This reality
With new provided boiler, its advantage is as described above.
In a kind of preferred embodiment on first sensor 2 and second sensor 3, the first sensor 2 and
Two sensors 3 can be wind pressure sensor, and the blast of inlet side that so can directly to air filtering core 1 and air side is surveyed
Amount.Certainly, first sensor 2 and second sensor 3 can also be air flow sensor or air velocity transducer etc., can equally reach
Measure the purpose of the both sides blast of air filtering core 1.
And in a kind of preferred embodiment on monitoring modular 4, the monitoring modular 4 specifically may include pressure difference switch
401 and audible-visual annunciator 402.Wherein, pressure difference switch 401 is connected with first sensor 2 and the signal of second sensor 3 simultaneously, such as
This, the aspiration pressure of the air filtering core 1 that first sensor 2 and second sensor 3 will just be detected respectively sends with wind pressure is gone out
To pressure difference switch 401, and pressure difference switch 401 just carries out mathematic interpolation to both after receiving, and obtains pressure difference.Audible-visual annunciator
402 are connected with the signal of pressure difference switch 401, after the pressure difference that pressure difference switch 401 will be calculated is sent to audible-visual annunciator 402,
Be compared for the pressure difference and predetermined threshold value by control module or MCU inside audible-visual annunciator 402 etc., if pressure difference switch 401
When the pressure difference for calculating is more than or equal to predetermined threshold value, then alarm is sent at once, notify that staff changes air filtering core 1,
Investigation hidden danger.Certainly, if the pressure difference that pressure difference switch 401 is calculated is less than predetermined threshold value, any operation can not be done.
On predetermined threshold value, it is preferable that can by the predetermined threshold value be specifically configured to the detected value of first sensor 2 10%~
20%, such as 10%, 15% or 20% etc., in this way, the aspiration pressure of the both sides of air filtering core 1 and the difference between going out wind pressure are in
In 10%~20%, as safe range.
Furthermore, it is contemplated that while monitoring modular 4 is warned, boiler is still within running status, and in a short time
Even if staff has known warning for monitoring modular 4, it is also likely to have little time to complete to change asking for the grade operation of air filtering core 1
Topic, is additionally arranged security module 5 in the present embodiment.The security module 5 is connected with the signal of monitoring modular 4, is mainly used in monitoring mould
Boiler power supply circuit is cut off while block 4 is warned.Specifically, the security module 5 can be the structures such as controlled breaker.Such as
This, when monitoring modular 4 is warned, the rapid power supply by boiler of security module 5 is cut off, and makes its operation suspension, gives work people
Member provides and changes air filtering core 1, the operating time of investigation hidden danger.
Moreover, it is contemplated that while being warned, staff may not be nearby for monitoring modular 4, it is impossible to and
When know the situation of dangerous situation, communication module 6 is additionally arranged in the present embodiment.The communication module 6 is connected with the signal of monitoring modular 4, main
Be used to alarm is sent to by network communication mode while monitoring modular 4 is warned the communication apparatus of user, than
Such as the communication module 6 can be GPRS communication modules or 3G communication modules, in this way, staff can be long-range by communication apparatus
Know the behaviour in service of air filtering core 1.
The present embodiment also provides a kind of boiler, main to be supervised online including body of heater and the air filtering system being arranged on body of heater
Device is surveyed, wherein, the air filtering system on-Line Monitor Device is identical with the above, and here is omitted.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.Various modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can in other embodiments be realized in the case where spirit or scope of the present utility model are not departed from.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
