With the exhaust treatment system of clarifier-tank
Technical field
The utility model relates to a kind of exhaust-gas treatment field, especially a kind of exhaust treatment system with clarifier-tank.
Background technology
According to the enhancing of current industry and commerce development and environmental consciousness, going from bad to worse of living environment is subject to the most attention of society and industrial circle, wherein, flourish due to industry, rapidly, the area that harmful exhaust is stretched is vast in air pollution diffusion, the direct harm people through respiratory system of the polluter in waste gas healthy, for this development trend, the various technology and equipment about environment-friendly engineering is constantly developed thereupon.The purified treatment of relevant industrial waste gas is then face one of most important problem in many environmental protection cases.
At field of industrial production, often can produce some toxic harmful exhaust gas, and for the process of waste gas, we generally adopt air exhauster to collect waste gas, and be nontoxic material via a series of purifier by the poisonous and harmful substance decomposition reaction in waste gas.According to the difference of required process exhaust gas constituents, the composition of conventional exhaust treatment system is also different, is generally undertaken selectively being combined into a whole set of exhaust treatment system by equipment such as cooling system, adsorption tower, incineration tower, spray chamber, supernatant cistern, clarifier-tanks.Existing clarifier-tank is generally the pond body of a sealing, take up in the body of pond in and the reactant liquor of poisonous and harmful element in waste gas, the position near bottom surface on the body of pond offers pond import, and this pond import is used for passing into waste gas in the body of pond; Pond body offers pond outlet near the position of bottom surface, and the outlet of this pond is used for the discharge of gas in the body of pond.During work, the liquid level of reactant liquor will far away higher than pond import, and by aforementioned manner, waste gas needs through reactant liquor after entering pond body, and now reactant liquor is undertaken contacting and reacting by with the poisonous and harmful substance in waste gas.
In actual conditions, waste gas is very short through the time of reactant liquor, in the time that very difficult guarantee is so short, venomous injurant mass-energy in waste gas fully contacts with reactant liquor and is neutralized, for this reason, a lot for the treatment of facility is the mode by increasing pond body, makes waste gas successively by different pond bodies, thus ensures fully carrying out of reaction.But this mode needs to increase large quantity space, but also adds equipment purchase expense, and maintenance expense.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of exhaust treatment system of band clarifier-tank that waste gas fully contacts with reactant liquor and reacts in clarifier-tank that ensures.
The utility model solves the technical scheme that its technical problem adopts: a kind of exhaust treatment system with clarifier-tank, comprise adsorption tower, incinerate tower and described clarifier-tank, described clarifier-tank is enclosed construction, pond import and circulation import is offered bottom this clarifier-tank, clarifier-tank top offers pond outlet and loop exit, also includes:
Supersonic generator, is installed in clarifier-tank;
Circulation pipe, this circulation pipe comprises pipe import and pipe outlet, and wherein pipe import is connected with clarifier-tank inside by loop exit, and pipe outlet is connected with clarifier-tank inside by circulation import;
For the air pump of gas circulating flow in circulation pipe and clarifier-tank, this air pump is connected with circulation pipe.
The beneficial effects of the utility model are: by the work of supersonic generator, and the bubble in clarifier-tank is occurred " cavitation effect ", and namely bubble occurs constantly to break, thus ensure that in bubble, composition fully can contact with reactant liquor.Simultaneously, in order to ensure the abundant of contact further, by the cooperation of circulation pipe and air pump, the gas of emersion reactant liquor is imported bottom clarifier-tank again, make it contact with reactant liquor again, if necessary, can closed cell import and pond outlet, only carry out the iterative cycles of circulation pipe and purification pool gas, so both thoroughly can realize the adequacy contacted.
When exhausted air quantity is constant, if waste gas passes into reactant liquor from an opening, then the area that waste gas contacts with reactant liquor is limited, even if there be the auxiliary of supersonic generator, effect also will be restricted, therefore, be also provided with gas-distributing pipe in clarifier-tank, this gas-distributing pipe one end is closed, the other end is connected with pond import, the surface of gas-distributing pipe offers some points of pores, realizes porous air inlet by point pore increased, thus increases the contact area with reactant liquor.
In order to break up bubble further, be also provided with gas separating net in clarifier-tank, this gas separating net covers at outside gas-distributing pipe, and some air pockets can be divided into minute bubbles by the mesh on gas separating net.
Preferably be set to, the working end of supersonic generator is corresponding with gas separating net.
In order to control the keying of each air inlet and gas outlet, and ensure that the gas exporting out from pond is that fully neutralization is complete, then exhaust treatment system also includes: the pond inlet valve opened and closed for pond import, is installed on pond import department; For the pond outlet valve that pond outlet opens and closes, be installed on exit, pond; For the circulating valve that circulation pipe opens and closes, be installed on circulation pipe place.By closing pond inlet valve and pond outlet valve, pressure opening circulating valve, thus the abundant circulation realizing waste gas in clarifier-tank, until determine that in waste gas, part or all of poisonous and harmful substance all neutralizes complete.
In order to improve automatization level, then exhaust treatment system also includes: three relays, is connected respectively and keying for controlling pond inlet valve, pond outlet valve and circulating valve with pond inlet valve, pond outlet valve with circulating valve; For controlling the control unit of each relay on-off.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
As Fig. 1, shown in 2, the present embodiment comprises adsorption tower (not shown), incinerate tower (not shown) and clarifier-tank 1, wherein clarifier-tank 1 is enclosed construction, pond import 111 and circulation import 112 is offered bottom this clarifier-tank 1, clarifier-tank 1 top offers pond outlet 121 and loop exit 122, supersonic generator 2 is installed in clarifier-tank 1, clarifier-tank 1 is outer is also connected to circulation pipe 3, this circulation pipe 3 comprises pipe import 31 and pipe outlet 32, wherein pipe import 31 is connected with clarifier-tank 1 inside by loop exit 122, pipe outlet 32 is connected with clarifier-tank 1 inside by circulation import 112, circulation pipe 3 is connected to air pump 4, circulating of gas in circulation pipe 3 and clarifier-tank 1 is realized by air pump 4.In clarifier-tank 1, gas-distributing pipe 5 is also installed, this gas-distributing pipe 5 one end is closed, and the other end is connected with pond import 111, and the surface of gas-distributing pipe 5 offers some points of pores 51, realize porous air inlet by point pore 51 increased, thus increase the contact area with reactant liquor.Meanwhile, gas-distributing pipe 5 is outer is also covered with gas separating net 6, by the mesh on gas separating net 6, some air pockets is divided into minute bubbles.The working end of supersonic generator 2 is corresponding with gas separating net 6.
