Abstract
The invention discloses a wet dust removal system and method. The system comprises a first deduster and a second deduster, wherein the first deduster is communicated with a nanometer foam machine, nanoscale foam groups are generated to be subjected to convection with smoke, so that physical and chemical reaction in the smoke are accelerated, an ideal dust removal effect is achieved, meanwhile, through the arrangement of the second deduster, acidic or alkaline impurities and other impurities in the smoke are further removed, and the pollution to the environment and the harm to human bodies caused by the smoke are reduced.
Description
Technical field
The present invention relates to airhandling equipment and method, particularly relate to a kind of wet dedusting system and method.
Background technology
The general principle of wet scrubber is the larger particles allowing liquid or drop and relatively little grit contact, combine the easy trapping of generation.In this process, grit grows up to large particle by several method.These methods comprise larger drop and grit are combined, and grit absorbs moisture thus quality (or density) to be increased, or the formation of condensable particle and increase under lower temperature in deduster.
Wet scrubber manufacturing cost is relatively low, but for chemical industry, spray paint, the dust with moisture content, viscosity and penetrating odor that glaze spraying, the industry such as pigment produce is optimal dedusting method.Diameter can be that the liquid state of 0.1-20 microns or solid particles remove from air-flow by wet scrubber effectively, meanwhile, also can remove part gaseous contaminant.It has that structure is simple, floor space is little, operation and easy to maintenance and purification efficiency advantages of higher, the air-flow of high temperature, high humidity can be processed, water also can be utilized to remove a part of peculiar smell may minimizing of catching fire, explode, if harmful gas (as a small amount of sulfur dioxide, salt acid mist etc.), absorbent can be prepared absorb in cleaning solution.
The common at present wet scrubber of existing wet scrubber is the suction utilizing centrifugal high pressure fan, dusty gas is pressed onto in the tank that certain altitude water is housed, and water-bath can a part of dust adsorption in water.After uniform shunting, gas flows from the bottom up, and high-pressure nozzle then sprays water smoke from top to bottom, the grit of trapping remainder.Existing deduster dust removing effects is undesirable.
The people such as rain fruit (Hugo) propose solid liquid interface and there is nano bubble in the process of research surface hydrophobicity long-range mechanism of action, due to the difference of experiment condition, the pattern of various countries scientist to nano bubble has different views, and the bubble be present in liquid usually size being less than hundreds of nanometer is called nano bubble.The manufacture of nano bubble has multiple method, as directly method, external source method, alcohol water Shift Method, chemical reaction method etc. are put in leaching.The advantages such as nano bubble has substantial amounts, and surface area is huge, and translational speed is slow, dissolved oxygen content is large, in environmental protection industry (epi), Metallurgy Industry, aquatic products industry and agricultural, sewage disposal.Health fields etc. have huge applications prospect.
