Description
Technical field
The utility model relates to airhandling equipment, particularly relates to a kind of wet dedusting system.
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.
Summary of the invention
The utility model provides a kind of wet dedusting system to solve deficiency of the prior art, efficiency of dust collection is high, water loss is few, except dust quantity large.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of wet dedusting system, comprise the first deduster and the second deduster that are communicated with successively, nanometer foam machine is provided with bottom the first described deduster, to be communicated with the spray equipment on the first deduster top by the first circulating line and to form peripheral passage, first deduster lower end is provided with the first air inlet, upper end is provided with the first air outlet, first air outlet is communicated with by second air inlet of ventilation shaft with the second deduster lower end, collecting tank is provided with bottom second deduster, collecting tank is communicated with the spray equipment in the second deduster by the second circulating line, collecting tank is connected with medicine system, second dust remover roof is provided with the second air outlet.
As a kind of preferred version of wet dedusting system described in the utility model, the second described air outlet is provided with drying device, preferred drying device is macromolecule desciccator diaphragm, can certainly be other drying devices, water vapor filtering in gas after scrubbing is got off continue to use, steam can be reduced on the one hand to enter in a large number in air, also can reduce the consumption of recirculated water in the second deduster on the other hand.
