Abstract
The utility model relates to a water jet ventilating dust collector-a cyclone draught dust collector, which is suitable for dust collection of all the working places generating dust. A water jet flow eductor (15) is breadthways arranged in a cyclone dust collector (12) which is composed of a cyclone draught cylinder (5), a mixing coacervation cylinder (6) and a pollution discharge cylinder (7). Compared with the prior art, a cyclone draught nozzle (4) on the water jet flow eductor (15) can increase the exchange ability of a boundary layer and the diffuser angle of the water-jet flow and make the draught volume increased about 30%, and the dust collection efficiency can reach more than 99%. The utility model has simple structure, easy fabrication, convenient use and maintenance, small draft resistance and wide application range.
Description
The utility model relates to a kind of water jet ventilating dust-arrester, is applicable to that all produce the udst separation of the workplace of dust.
In the prior art, with the utility model the most approaching be a kind of water jet dust-removing device for boiler that Chinese patent 91204974.X provides.This device is made up of water jet injector and rotary dust separator two parts.Water jet injector shell is fixed on the air inlet pipe of dust separator with flange.The dusty gas that boiler is discharged is mixed by water smoke in water-jet circulation injector, and then enters dust separator.Dust after moisture is handled the back through special dust separator eddy flow and is fallen, and discharges through blow-off pipe.The gas that purifies is discharged through exhaust core tube.But this utility model adopts common water-jet circulation injector, and air inducing efficient and efficiency of seizing dust are all lower, also need purify through special-purpose cyclone separator simultaneously, its complex structure, and the resistance of ventilation is bigger.
The purpose of this utility model is to avoid the weak point in the above-mentioned patented technology and a kind of high-efficient ventilation dust arrester simple in structure that water jet fan and cyclone dust are organically combined is provided.
The purpose of this utility model can realize by following measure:
Eddy flow air inducing dust arrester, its water jet injector places in the cyclone dust, the water jet injector is fixed on by pressure cap and sealing gasket by eddy flow air inducing nozzle on the screw thread plush copper of rigidity bend pipe end to be formed, cyclone dust system is made up of for three sections eddy flow wind guiding tube, mixing cohesion tube and pollutant discharge tube, and with bolt it is connected as one by flange.
The purpose of this utility model can also realize by following measure:
Eddy flow air inducing dust arrester, its eddy flow air inducing nozzle is built-in with a conveyor screw, and this spirochetal rotation direction is dextrorotation, and lift angle is 30 °～60 °, is made by high-abrasive material.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of the utility model eddy flow air inducing dust arrester;
Fig. 2 is the water jet injector profile of the utility model eddy flow air inducing dust arrester
Below in conjunction with accompanying drawing the utility model is explained in detail:
As shown in Figure 1 and Figure 2, eddy flow air inducing dust arrester is made of the eddy flow dirt device (12) of built-in water jet injector (15).Cyclone dust (12) is horn-like by the upper end, the bottom is that (7) three sections compositions of pollutant discharge tube that a sewage draining exit (14) is housed on tube (6) and the sidewall are condensed in eddy flow wind guiding tube (5), tubular or the trumpet-shaped mixing of tubular, and with bolt (13) it being connected as one by flange (11), water jet injector (15) then is fixed on by pressure cap (9) and sealing gasket (10) on the screw thread plush copper of rigidity bend pipe (3) end by eddy flow air inducing nozzle (4) to be formed.The water jet injector is horizontally placed in eddy flow wind guiding tube (5) the tubular section by welding, just make eddy flow air inducing nozzle (4) axis overlap with eddy flow wind guiding tube (5) axis, rigidity bend pipe (3) other end then stretches out eddy flow wind guiding tube (5) wall and connects by pipe joint (2) and high-pressure rubber pipe (1) outward.The utility model organically combines water jet injector (15) and cyclone dust (12).During work, the High-Pressure Water by high-pressure pump is supplied with enters in the eddy flow air inducing nozzle (4) through high-pressure rubber pipe (1), pipe joint (2) and rigidity bend pipe (3).Make High-Pressure Water after eddy flow air inducing nozzle (4) ejection, form the jet beam of rotation, it does axial eddy motion at a high speed in eddy flow wind guiding tube (5).Dusty gas in the tube is changeed by band under the effect in rotation boundary layer, forms parital vacuum, realizes the purpose of air inducing.Rotating vortex and ash-laden gas physical efficiency are mixed exchange fully in mixing cohesion tube (6).Behind a segment distance, the water dust cell space is condensed into water dust and drips, and finally falls in the pollutant discharge tube (7), by sewage draining exit (14) sewage is entered in the water treating pond.
The pull-shaped cavity segment in the interior garden of eddy flow air inducing nozzle (4) of the utility model water jet injector (15) is built-in with a conveyor screw (8), and the rotation direction of this conveyor screw (8) is dextrorotation, and lift angle is 30 °～60 °, is made by high-abrasive materials such as ceramic hard alloys.Because conveyor screw (8) has produced rotation effect to the current of high-speed motion, make the water stream of ejection be the rotating vortex shape, this rotating vortex is compared with general jet, owing to have the effect of vortex, its angle of flare increases, the ability of boundary layer and dusty gas exchange on every side improves greatly, because of all improving greatly than its air inducing efficient and efficiency of dust collection.
The utlity model has following advantage:
(1) it organically is combined as a whole waterpower air inducing device and cyclone dust, and is simple in structure, easy to manufacture, uses easy to maintenancely, and flowing resistance is little.
(2) owing to adopted eddy flow air inducing nozzle (4), increased the angle of flare and the boundary layer exchange capacity of jet, can make the air inducing amount increase about 30%, dust removal efficiency can reach more than 99%.
(3) scope of application is big, produces the udst separation of the workplace of dust applicable to all.
