The beneficial effects of the utility model are: by the rotating speed adopting frequency converter to regulate exhaust blower, thus can adapt to the air quantity requirement needed for exhaust duct.Employing static pressure transducer can detect the pressure reduction inside and outside exhaust duct.This exhaust system is energy-conservation, be easy to regulate.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram of a kind of exhaust system of the utility model.
[detailed description of the invention]
Below the preferred embodiment of utility model is described in further detail.
As shown in Figure 1, a kind of exhaust system, comprises exhaust blower M, exhaust duct, frequency converter, frequency conversion control circuit (controller) and static pressure transducer.
Described static pressure transducer is arranged in described exhaust duct, for detecting exhaust duct inside and outside differential pressure, and the difference of the air pressure namely inside the air pressure of exhaust duct outside and exhaust duct.Frequency conversion control circuit is electrically connected with frequency converter, described exhaust blower is electrically connected with described frequency converter, described frequency converter is used for the rotating speed regulating described exhaust blower according to the setting air quantity of exhaust duct, if the setting air quantity needed for exhaust duct is large, then frequency conversion control circuit is by controlling frequency converter, as improved the frequency of frequency converter, improve the rotating speed of exhaust blower, thus can the air quantity of increasing exhaust pipeline; If the setting air quantity needed for exhaust duct is little, then frequency conversion control circuit is by controlling frequency converter, as reduced the frequency of frequency converter, reducing the rotating speed of exhaust blower, thus can reduce the air quantity of exhaust duct.
In one embodiment, can take further measures and ensure exhaust duct inside and outside differential pressure in setting with in scope, thus noise is less.
In one embodiment, the air intake vent of exhaust system comprises vent cabinet, and described vent cabinet comprises form, and it is comparatively large that described form is in opening angle, then required setting air quantity is comparatively large, to discharge air in time; As described in form to be in opening angle less, then required setting air quantity is less, also can discharge air in time.
In one embodiment, exhaust system also comprises fuse FU, and described frequency converter has three-phase input end R, S and T, and each phase input accesses supply line (L1, L2 and L3) by corresponding fuse FU.
In one embodiment, exhaust system also comprises air switch QS, and described frequency converter has three-phase input end R, S and T, and each phase input accesses supply line (L1, L2 and L3) by corresponding air switch QS.
Exhaust system also comprises Switching Power Supply, and it can provide DC voltage, to controller and static pressure transducer W1, W2 ... power.
Exhaust system also comprises K switch 1, K2 ... and auxiliary reclay KA1, KA2 one to one ..., auxiliary reclay is normally opened relay, and after K switch 1 is closed, corresponding auxiliary reclay KA1 closes, the corresponding ground terminal ground of controller.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the scope of patent protection that the utility model is determined by submitted to claims.
