A charged fog cannon for eliminating urban dust and smog pollution

Abstract

The invention discloses a charged fog cannon for eliminating urban dust and smog pollution, which belongs to the technical field of long-distance fog spraying and is a fog cannon with the function of charged water mist. Composed of high-voltage power supply, water source, pump and support frame. It is characterized in that the charging nozzle is fixed on the front end of the air cylinder through the pipeline, and is installed on the axis of the air cylinder, and the outer edge of the charging nozzle is aligned with the edge of the air cylinder. In the present invention, after charging the mist generated by the charged spray head in the spray area, the air delivery system performs secondary atomization on the mist, and can also reduce the drift of the mist through the charging technology, and increase the concentration of the charged mist on the dust area. The deposition and adhesion rate, after the droplets are charged, the ability to capture and collect dust with a diameter of less than 2 microns is significantly enhanced, solving the problem of long-term uncontrollable dust pollution.

Description

technical field [0001] The invention relates to the technical field of remote spraying fog, in particular to a charged fog cannon for 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 materials) t...

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
