The specific embodiment
Before describing the present invention in detail, will explain below to relate to filtration control of dust technology of the present invention, impulse jet clean method and Coanda effect:
Filtering the control of dust technology is to be contained in the dust of handling in the gas by using dust-collecting filter to remove.When dust granule was collected on the filter, the differential pressure of filter both sides increased.Thereby the process of the dust of the regular separated and collected of needs on filter surfaces and this are called cleaning filtration hereinafter.Be generally used for filtering filtrating and cleaning method in the control of dust technology comprise by spray at once compressed air separates dust from filter surfaces impulse jet clean method, by with handle side that gas passes filter and go up supply air flow in the opposite direction and come the adverse current clean method of cleaning and filtering and the clean method that shakes that comes cleaning and filtering by direct vibration dust-collecting filter.
About the impulse jet clean method, the impulse jet cleaning device generally includes: be used for storing compressed-air actuated clean air storage box to be sprayed, be used for controlling the clean air control valve from the compressed-air actuated amount of clean air storage box transmission when cleaning; Be used for to be sent to a plurality of clean air jet pipes of each dust-collecting filter by the compressed air of clean air control valve transmission; And be attached to each clean air jet pipe and be used for a plurality of clean air nozzles of compressed air actual ejection to dust-collecting filter inside.
And in the impulse jet clean method, the clean air control valve is opened the very short time, less than 0.2 second, to allow compressed air immediately from nozzle ejection.Then, the air of direct injection and near the air short time of inducing by high velocity jet flow into dust-collecting filter, thus expansion dust-collecting filter and remove and be deposited on the lip-deep dust of dust-collecting filter.The filter cleaning system of apply pulse injection clean technologies is accomplished in various ways.
Coanda effect is the physical phenomenon of being found by Henri Coanda.When fluid was crossed object surfaces with high velocity stream, it was along the object surfaces fast moving, and therefore object fluid pressure on every side reduces.This is called as Coanda effect.This phenomenon appears at mobile fluid when spraying by narrow gap such as capillary, and when existing wall surface crooked on fluid flow direction nearby, fluid flows along this curved surface bending.
For example, Coanda effect is applied to aircraft.When having the wing of the end face of different curvature and bottom surface, the pressure on the end face reduces at air.So, the action and reaction between the air that flows downward along wing surface by the wing with fast speed of the climbing power of aircraft produces.
Therefore, Coanda effect can be applicable to various fields and aircraft field.Just, Coanda effect is applied to the industrial circle that different exhausts and ventilation, the electric wire that is used to communicate by letter or optical fiber or cleaning large-sized boiler are installed widely.
