3. A dust removing method of a wet dust removing apparatus for performing inflammable dust and deposit removal according to claim 1 or 2, comprising the steps of:
step one, capturing primary sedimentation of dust
The explosion-proof centrifugal machine enables gas with dust to enter the first spraying box from the air inlet, the spray head on the movable water pipe sprays water mist, the rotary spray head drives the movable water pipe to rotate at a constant speed, all-directional water mist is formed in the first spraying box, dust and water drops of the water mist are fused to form dust water drops, and the dust water drops with large volume are descended to the bottom of the box body under the action of self gravity and inertia;
step two, secondary dust capture and sedimentation
Pumping the water mist generated in the first spraying tank to a second spraying tank through an explosion-proof centrifugal machine, wherein the second spraying tank is provided with three spraying layers, the spraying layers are provided with rotary nozzles, the volume of water drops in the water mist sprayed out of each spraying layer is different, and the water drops with dust are collided and combined with the water mist sprayed out of the spraying layers so as to increase the self weight of the water drops with dust, settle under the action of the self weight and are guided to a sewage filter along with water flow;
step three, dust settling and water resource circulation
Through the dust capture of the first spraying box and the second spraying box, water drops with dust are settled under the action of gravity inertia, flow into the three-stage sewage filtering tank through a pipeline, and are filtered and settled through multiple filtering layers, so that the treated water is recycled through a recycling waterway;
step four, water-gas separation
Pumping the treated gas to the top of the second spraying box, separating water mist through a defogging filter, leaving water in the second spraying box or on the water mist filter, and discharging the gas from an exhaust port;
step five, cleaning the interior of the spraying box and transporting sediments
Scrape the wall clean to the inside four sides of box through inner wall cleaning device regularly automatically, clean after and the precipitate piles up the certain degree, clear away accumulational precipitate through precipitate collection device and conveyer, prevent that the box is inside to pile up too many water routes of appearing and block up and influence purifying effect because of the dust.
