Abstract
The utility model relates to a Rafael pipe jet flow air mixing device which is used in a wet flue gas desulfurization system (WFGD) or similar fields for preventing serum tanks from sediment. The Rafael pipe jet flow air mixing device comprises a serum tank and a plurality of turbulent flow pipes which are arranged on the inner wall of the serum tank, and further comprises an air distributor, a Rafael spraying pipe and a valve, wherein a gas outlet end of the Rafael spraying pipe is connected with air inlet ends of the turbulent flow pipes, the air inlet end of the Rafael spraying pipe is connected with an air outlet end of the air distributor, and a valve is arranged between the turbulent flow pipes and the Rafael spraying pipe. The Rafael spraying pipe is utilized to accelerate air with certain pressure to be sprayed into serum, and the air is overturned and lifted under the effect of initial speed and flotage to drive surrounding serum to overturn and roll, thereby achieving the mixing effect.
Description
Technical field
The utility model relates to a kind of wet method fume desulfurizing system (WFGD) or the air agitating device of similar field for preventing that the serum pot deposition is provided with of being used for.
Background technology
The agitator that prevents the serum pot deposition at present in known this field is the metal blade agitator, generally be installed in the jar top, rotate with certain speed by driven by motor metal shaft and metal blade, blade stirs slurries, thereby prevents that the solid particle in the slurries from depositing the problems such as causing line clogging in the system, slurries inefficacy that hardens.
The metal blade agitator system is made up of reductor, motor, support, gripper shoe, mechanical seal, axle, wheel hub, blade, water conservancy diversion arc plate, blade locknut.Owing to contain a certain amount of chlorion and other corrosion compositions in the desulfurization slurry, therefore the material require with the slurries contact portion adopts corrosion resistant alloy material; Owing to contain solid particle in the slurries, the moving component that contacts with slurries also must be wear-resistant in addition.It is that mechanical sealing member damages easily that there is another problem in the metal blade agitator, frequently causes the spillage accident.
Existing another slurries mixing plant is a utility model patent---air flow stirring apparatus (patent No. 01268689.1).The blowpipe that it plays stirring action is arranged on the serum pot bottom, and the corrosivity of being blown particle in the slurries and slurries can cause wearing and tearing and corrodes equally blowpipe and connecting pipe.
Summary of the invention
Technical problem: technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and the LAVAL pipe jet air stirring device that a kind of tube connector corrosion is low, wearing and tearing are low is provided.
Technical scheme: the utility model solves the technical scheme that its technical problem adopts and is:
A kind of la farr pipe air-spray agitating device, comprise serum pot and be arranged on a plurality of turbulated tubes on the serum pot inwall, also comprise air distributor, Rafael nozzle and valve, the outlet side of described Rafael nozzle is connected with the inlet end of described turbulated tube, the inlet end of described Rafael nozzle is connected with the outlet side of described air distributor, and described valve is arranged between turbulated tube and the Rafael nozzle.
Utilize the stirring of high velocity air rather than mechanical rotation part realization, reach the purpose that prevents the slurries deposition slurries.In order to realize that the acceleration of gas has been utilized la farr pipe.La farr pipe comprises convergent-divergent section and diffuser, and purpose is to change the motive fluid flow velocity, reaches Peak Flow Rate in reducing place, and the reducing rear is a segment that contracts earlier and afterwards expand then, its objective is the flow velocity of further increase power gas.Air or compressed air pass through the air distributor mean allocation in each fluidic device, quicken through la farr pipe then, enter turbulated tube after reaching certain speed, air is injected enters in the slurries for turbulent flow, because turbulent flow and buoyancy, air is ascension in slurries, and the slurries motion reaches the effect of stirring around driving.The another one purpose of high velocity air is to make jet pipe as forming a gas shield layer, can reduce wearing and tearing and the corrosion of slurries to jet pipe.
Beneficial effect: because the LAVAL pipe jet air stirring device movement-less part, the wearing and tearing possibility reduces, so the parts that contact with slurries can be selected nonmetallic materials for use, increases the anti-corrosion capability of equipment.This equipment does not need special sealing device yet, the accident of the frequent damage of seal can not occur.Owing to the existence of high velocity air, the jet pipe outside can form a gas shield layer, has effectively reduced wearing and tearing and the corrosion of slurries to jet pipe in addition.The another one advantage of LAVAL pipe jet air stirring device is that member is few, and is simple in structure, and reliability is high more a lot of than metal blade agitating device.It can also regulate the size of injection air amount very easily by valve, thereby is that different slurries amounts is adjusted different stirring intensities.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the vertical view 1 of air agitating device.
Fig. 2 is the Front view 2 of air agitating device.
Have among the figure: air or compressed air 1, air distributor 2, slurries 3, serum pot tank skin 4, valve 5, turbulated tube 6, la farr pipe 7.
The specific embodiment
LAVAL pipe jet air stirring device is made up of air distributor 2 and fluidic device, and wherein fluidic device is made up of la farr pipe 7, valve 5 and turbulated tube 6.Air distributor generally is arranged in the serum pot periphery wall, on average disposes fluidic device according to the serum pot diameter then.
Air or compressed air 1 arrive each la farr pipe 7 by air distributor 2 mean allocation, air accelerates to speed V (10m/s＜V＜100m/s) through la farr pipe 7, the air that quickened enters turbulated tube and sprays in the slurries, air ascension under turbulent flow and buoyancy function is rolled, the slurries upset is rolled around driving, and reaches well-beaten effect.
The effect of valve 5 is control injection air amounts, thereby the control stirring intensity can also prevent that slurries from pouring in down a chimney in addition when maintenance.
La farr pipe 7 and supporting valve 5 and turbulated tube 6 are evenly distributed at serum pot tank skin 4, and quantity is 3～20, according to serum pot size and the decision of slurries physical attribute.
