Electrical charged fog gun for effectively eliminating raising dust and haze pollution in city

Abstract

The invention discloses an electrical charged fog gun for effectively eliminating raising dust and haze pollution in a city, belonging to the technical field of remote fog ejecting. The electrical charged fog gun is a fog gun with an electrical charged fog function. The technical scheme is as follows: the electrical charged fog gun comprises an axial flow fan, an electrical charged nozzle, a high-pressure power supply, a water source, a pump, a support frame and other main parts. The electrical charged fog gun is characterized in that the electrical charged nozzle is fixed on the top end of a ventilator through a pipeline and arranged on an axial line of the fan, and the outer edge of the electrical charged nozzle is aligned to the edge of the ventilator. According to the electrical charged fog gun, after fog drops generated by the electrical charged nozzles are charged in a fog ejecting region, and then secondarily atomized through an air blowing system, thus fog drop drift can be reduced through a charge technology, the deposition rate and the adhesive rate of the electrical charged fog drops on a raising dust region are increased, the capacity of capturing the dust with a diameter of below 2 micrometers by the charged fog drops is remarkably enhanced, and the problem that the raising dust pollution can not be treated for a long time is solved.

Description

technical field [0001] The invention relates to the technical field of remote fogging, in particular to a charged fog cannon for effectively eliminating urban dust and smog pollution. Background technique [0002] At present, in the known fog cannons, the dust collection mechanism is mainly inertial collision, diffusion and agglomeration. Because the inertial collision and agglomeration mechanism play the main role, there are two main disadvantages in the collection of respiratory dust: one is because the inertia of respiratory dust is small, when it is about to collide with water mist particles, it will change its trajectory by itself and go around the fog Particle movement is extremely difficult to be captured by water mist. Second, even if there is a small amount of respiration dust colliding with water mist particles, it is easy to separate due to the small cohesion force, which is why the collection efficiency of water mist particles (especially larger water mist mater...

Problems solved by technology

Because the inertial collision and agglomeration mechanism play the main role, there are two main disadvantages in the collection of respiratory dust: one is because the inertia of respiratory dust is small, when it is about to collide with water mist particles, it will change its trajectory by itself and go around the fog Particle movement is extremely difficult to be captured by water mist

Second, even if a small amount of respiration dust collides with water mist particles, it is easy to separate due to the small cohesion force. This is the reason why water mist particles (especially larger water mist materials) have low collection efficiency for respiration dust.

Among the existing dust prevention (reduction) measures, the collection efficiency of ordinary fog cannon spray on respiratory dust is only 20~30%, which cannot effectively control respiratory dust
