Provided are a control system and a control method of an energy-saving anti-explosion fan. The control system of the energy-saving anti-explosion fan comprises the anti-explosion fan which is connected with a fan power controller connected with a flammable gas concentration sensor. The invention further provides the control method of the control system of the energy-saving anti-explosion fan. According to different flammable gas concentration in the working environment, the output power of the anti-explosion fan can be changeable, thereby being favorable for improving quality of the working environment, reducing the flammable gas concentration, reducing energy consumption and abrasion of the anti-explosion fan, and being reliable in running, high in safety performance and good for improvement on production benefits.
Description
Technical field
The present invention relates to a kind of energy-saving explosion-proof blower fan control system and controlling method.
Background technique
Have the place of inflammable gas at mine, factory etc., blast in order to prevent inflammable gas from working space, accumulating, explosion-proof fan has obtained extensive use.Explosion-proof fan has important function aspect the raising working environment Safety performance.In existing explosion-proof fan was used, explosion-proof fan carried out work with single power as a working cell independently during work mostly, can not be according to the automatic transform power of the combustable gas concentration in the environment, and energy consumption is higher.Though blower fan effect aspect control combustable gas concentration, raising working environment quality is very obvious; But the combustable gas concentration most of the time in the working environment is all very low; Even naked light is arranged can not blast yet; And this moment, explosion-proof fan often is operated under the single higher-power state, to energy-conservation, increase the benefit very unfavorable.
Summary of the invention
In order to overcome the above-mentioned defective that existing technology exists, the present invention provides a kind of energy consumption lower energy-saving explosion-proof blower fan control system and controlling method.
Technological scheme of the present invention is:
The present invention's energy-saving explosion-proof blower fan control system comprises explosion-proof fan, and said explosion-proof fan is connected with the power of fan controller, and the power of fan controller is connected with the combustable gas concentration sensor.
The controlling method of the present invention's energy-saving explosion-proof blower fan control system is: during work; The combustable gas concentration sensor is placed working environments such as mine, factory; Behind the combustable gas concentration of its working environment that is placed of combustable gas concentration sensor; The combustable gas concentration signal value that records is transferred to the power of fan controller, and the power of fan controller is according to the output power of the size control explosion-proof fan of combustable gas concentration.
The present invention is according to the difference of the combustable gas concentration in the working environment; Make that the output power realization of explosion-proof fan is variable, help improving the working environment quality, reduce combustable gas concentration; Reduce explosion-proof fan energy consumption and wearing and tearing; Reliable operation, Safety performance is high, and the raising of productivity effect is had very big benefit.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention;
Fig. 2 is the controlling method FB(flow block) of energy-saving explosion-proof blower fan control system embodiment illustrated in fig. 1.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
With reference to Fig. 1, present embodiment comprises explosion-proof fan 1, and explosion-proof fan 1 is connected with power of fan controller 2, and power of fan controller 2 is connected with combustable gas concentration sensor 3.
For the concentration of the inflammable gas in the Control work environment, set a combustable gas concentration threshold value C
0, this combustable gas concentration threshold value C
0Safe concentration for working environment.C
0Setting method be: record the Cmin C that inflammable gas in the working environment can be when lighting with experiment
Min, require regulation safety coefficient n (n > according to the working environment different security; 1), makes C
0Satisfy and concern C
Min/ C
0=n.It is P that the power of fan controller is set the explosion-proof fan lowest power
LP
LEstablishing method be: for the air that guarantees working environment is fresh, continue to extract out the inflammable gas in the working environment, the combustable gas concentration C in working environment<c
0The time, setting power of motor this moment is P, satisfies P<p
L, P
LValue can be adjusted by the staff, and target is the most energy-conservation output power of motor.
During work, the combustable gas concentration sensor is placed working environments such as mine, factory.Execution in step 01, beginning; Execution in step 02 then, and combustable gas concentration sensor 3 is monitored the combustable gas concentration value C in the working environment in real time, and this combustable gas concentration C signal value is passed to power of fan controller 2; After the execution of step 02, execution in step 03, power of fan controller 2 is judged this combustable gas concentration value C: when this moment combustable gas concentration value C more than or equal to combustable gas concentration threshold value C
0The time, execution in step 04, power of fan controller 2 sends instruction to explosion-proof fan 1, increases explosion-proof fan 1 power P, and along with the increase of explosion-proof fan 1 power, the concentration of inflammable gas descends in the working environment; When combustable gas concentration value C less than combustable gas concentration threshold value C
0The time, execution in step 05, combustable gas concentration sensor 3 is transferred to power of fan controller 2 with combustable gas concentration value C, and power of fan controller 2 sends instruction to explosion-proof fan 1, reduces explosion-proof fan 1 power to lowest power P
LLast execution in step 06 finishes; Realize thus to reduce the power consumpiton of explosion-proof fan 1, saving power.
Power of fan controller 2 sends the power output order according to analysis result to blower fan, the big or small corresponding corresponding fresh air mass flow of power of fan, and then combustable gas concentration is in a safe condition in the Control work environment.
The present invention is through the concentration of flammable hazardous gas in the explosion-proof fan 1 Control work environment; The air that guarantees working environment is fresh, has improved the working environment quality, reliable operation, and Safety performance is high.
