Description
Technical field
The utility model relates to a kind of electric cleaner airflow distribution device, and particularly a kind of choked flow of electric cleaner adds the flow guiding type airflow distribution device.
Technical background
Electric cleaner is low with its efficiency of dust collection height, resistance, the flue gas treating capacity big, heat resisting temperature advantages of higher and become that dust catching reclaims and the capital equipment of gas purification, has been widely used in industries such as non-ferrous metal, metallurgy, electric power, building materials, oil, chemical industry.The uniformity coefficient that air-flow in the electric cleaner distributes is directly connected to efficiency of dust collection.In order to make the dusty gas that flows into electric field evenly pass through electric field, before the electric field inlet, the inlet air flow distribution grid is housed, available technology adopting choked flow add the air-flow distribution form of water conservancy diversion, adopt the multilayer choked flow to add flow guiding type airflow uniform distribution plate at air inlet, by increasing the air-flow local resistance, the small-scale turbulent flow that the turbulent cut-off rule of touching taps into laminar condition will be advised greatly on the one hand; Make it to change on request direction by guiding device on the other hand, air-flow enters electric field inside uniformly, and dust content further descends.Choked flow adds the air-flow distribution form of water conservancy diversion except having improved airflow homogeneity, and it also has the function of pre-dedusting, and pre-dedusting is to utilize the confined space of import loudspeaker will collect dust to greatest extent, to reduce the load of electric field.When the dirt stream of high concentration entered electric precipitation import oviduct by flue, flue gas flow rate was reduced to about 1m/s gradually from 15～18m/s, crude particle dust sedimentation under the gravity effect.When primary air is flowed through distribution grid, air-flow is cut apart diffusion, make not vertical with the airflow-distribution board air-flow of original direction change direction, the sudden change of airflow direction is because the effect of inertia dust is separated.
For the electric cleaner of horizontal air inlet, the loudspeaker enlarging that multilayer choked flow of the prior art adds the employing of flow guiding type airflow uniform distribution device is single enlarging shape, has following deficiency: pre-efficiency of dust collection is lower, the service life of import loudspeaker is short.
Summary of the invention
The pre-efficiency of dust collection that the utility model has solved the prior art existence is lower, the short problem in service life of import loudspeaker, provides a kind of choked flow of electric cleaner to add the flow guiding type airflow distribution device.The enlarging that a kind of choked flow of electric cleaner adds the import loudspeaker that the flow guiding type airflow distribution device adopted is a two-part, and the back segment enlarging is bending downwards with respect to the leading portion enlarging; Spoiler is arranged at the inner chamber leading portion of import loudspeaker, and airflow-distribution board is arranged at the inner chamber back segment of import loudspeaker.The sheet metal thickness of import loudspeaker bottom is greater than other parts, and its inner surface lays enhancement Layer.The back segment enlarging bending of the import loudspeaker of two-part makes the wind speed of bottom lower downwards, and the suffered wind speed influence of crude particle dust in the sedimentation is reduced, and can make more crude particle dust be able to sedimentation, has improved pre-dust removing effects.Import loudspeaker bottoms adopt higher thickness and and inner surface enhancement Layer is set, can more effectively bear the collision impact of the crude particle dust of high-speed motion, make the import loudspeaker more wear-resistant, obtain its service life prolonging.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of choked flow of electric cleaner adds the flow guiding type airflow distribution device, include pre-small post-large import loudspeaker, spoiler, airflow-distribution board and several and be arranged at deflector on the airflow-distribution board, spoiler, airflow-distribution board are porous plate, the enlarging of described import loudspeaker is a two-part, and the back segment enlarging is bending downwards with respect to the leading portion enlarging; Spoiler is arranged at the inner chamber leading portion of import loudspeaker, and airflow-distribution board is arranged at the inner chamber back segment of import loudspeaker.The back segment enlarging bending of the import loudspeaker of two-part makes the wind speed of bottom lower downwards, and the suffered wind speed influence of crude particle dust in the sedimentation is reduced, and can make more crude particle dust be able to sedimentation, has improved pre-dust removing effects.
As preferably, leave the gap of 120～150mm between the lower edge of described spoiler and airflow-distribution board and the import loudspeaker lower wall.Set up the crude particle dust decline passway, the crude particle dust that deposits and be attached on the import loudspeaker base plate is flowed out outside the import loudspeaker fast.
As preferably, the sheet metal thickness of described import loudspeaker bottom is greater than other parts, and its inner surface lays enhancement Layer.To all directions motion, under the effect of gravity and inertia force, the crude particle dust of sedimentation is to import loudspeaker base plate collision impact in modes such as high speed, rotations for crude particle dust.Import loudspeaker bottoms adopt higher thickness and and inner surface enhancement Layer is set, the ability of the anti-collision impact of import loudspeaker base plate is strengthened, thereby more wear-resistant, obtain its service life prolonging.
As preferably, the left side that be arranged at airflow-distribution board of described air deflector below import loudspeaker import center line is in the above right side that is arranged at airflow-distribution board of import loudspeaker import center line.Make that the air velocity of bottom should be low than mean flow rate, help the collection of dust.
As preferably, described spoiler, airflow-distribution board both sides are the flanging structure.The spoiler both sides become U-shaped for the flanging structure, and the airflow-distribution board both sides are provided with the flanging of guide functions, have increased the airflow-distribution board rigidity widely, even under great eddy current effect, also can not produce like that as flat board and tear.
As preferably, described deflector is a triangle, and its outer surface is smooth.Deflector not only can guarantee the uniformity that air-flow distributes, and it also can the thick dedusting to the flue gas that enters electric cleaner, and its efficiency of dust collection is quite tangible.
As preferably, described deflector adopts to flexibly connect and is suspended on the airflow-distribution board, and a plurality of positions of airflow-distribution board two side planes are provided with the jockey that is connected with deflector.Be convenient to concrete condition, reach reasonable airflow distribution state by the link position of regulating deflector according to the air-flow distribution.The adjustment that air-flow is distributed is very convenient, and only needing to change the deflector hanging position can achieve the goal, and does not need perforate, perforations adding.
As preferably, the opening diameter on the described airflow-distribution board is Φ 55cm～Φ 90cm.Reduced fluid resistance greatly, fluid enters electric field more equably by the guiding of deflector.
Therefore, the utlity model has the characteristics such as long service life of pre-efficiency of dust collection height, import loudspeaker.
