Abstract
A kind of injection tube of sack-duster pulse deashing device, the utility model provides a kind of injection tube of sack-duster pulse deashing device, mainly comprise main tracheae, main tracheae arranges some points of bronchuses along airflow direction successively interval, at each point of bronchial end, nozzle is set, it is characterized in that, progressively diminish along a point bronchial caliber described in airflow direction, described each point of bronchial nozzle cross-section is equal, make along each nozzle of airflow direction injection flow and flow velocity equal, the throughput that effectively can solve all directions injection in prior art is different, affect the problem of removing dust and clearing ash.
Description
Technical field
The utility model relates to a kind of blowing device of sack cleaner deashing, particularly relates to a kind of injection tube of sack-duster pulse deashing device.
Background technology
Sack cleaner utilizes bag type filter elements to trap the dust in dusty gas, makes gas purification, removed the attached dirt being delayed at filter bag surface by deashing mechanism simultaneously, makes filter bag regenerate and recover the high-effective dust-removing equipment of its filtering function.Sack cleaner has the features such as efficiency of dust collection is high, working stability is reliable, concentration of emission is low, applied widely, easy to maintenance.
The utility model is for pulse pocket type dust catcher deashing device.Blowing device is the core of pulse pocket type dust catcher deashing.It, primarily of point gas tank and injection tube composition, point gas tank is provided with pulse valve, and pulse valve carries out pulse venting by control system timing.Injection tube mainly comprises main tracheae, on main tracheae, interval arranges some points of bronchuses, divides bronchial end to arrange nozzle at every root.Owing to filtering constantly carrying out of operating mode, the dust be attached on outside filter bag increases gradually, and equipment resistance increases thereupon.When equipment resistance reaches the value preset, just need to carry out deashing to filter bag.The compressed air in gas tank is divided to be controlled by pulse valve and be released instantaneously, corresponding filter bag is injected rapidly by the nozzle in injection tube, a large amount of cleaned airs simultaneously in air-purifying chamber are poured filter bag by secondary drainage, now air-flow forms strong shock wave from top to bottom and shakes in filter bag, because the tension force effect of filter bag produces backward acceleration simultaneously, thus shake off the dust being attached to filter bag appearance, reach the object of deashing.
Pulse jet air-flow is from head rearwardly flow process in injection tube, and the dynamic pressure of air-flow reduces gradually, and static pressure increases gradually, and when blast pass arrives injection tube end, dynamic pressure all changes static pressure into.Existing injection tube each point of bronchus caliber is equal, and the gas flow causing each point of bronchus to eject is also unequal, but is rule, formation winding-up uneven phenomenon from small to large, thus have impact on pulse dust cleaning effect, increases air-introduced machine energy consumption.
Utility model content
In order to overcome the shortcoming and defect of prior art, the utility model provides a kind of injection tube of sack-duster pulse deashing device, it is characterized in that point bronchus caliber set gradually along airflow direction progressively diminishes, and divide bronchial end that the identical nozzle in outlet is set at every root, make along the air-flow velocity of main tracheae each point of bronchus injection and flow equal, the throughput that effectively can solve each point of bronchus injection in prior art is different, the problem that affects removing dust and clearing ash.
The utility model solves the technical scheme that its technical problem adopts: a kind of injection tube of sack-duster pulse deashing device, mainly comprise main tracheae, on main tracheae, some points of bronchuses be set along airflow direction successively interval, at each point of bronchial end, nozzle is set, it is characterized in that, progressively diminish along a point bronchial caliber described in airflow direction, described each point of bronchial jet area is equal, make along each nozzle of airflow direction injection flow and flow velocity equal.
The utility model preferred version, arranges 10 to 16 pieces points bronchuses along airflow direction successively interval and arranges nozzle at each point of bronchial end.
The utility model preferred version, next root be adjacent along airflow direction point of bronchus divides the caliber between bronchus than being 1.005:1-1.02:1.
Accompanying drawing explanation
Fig. 1-Fig. 4 is the structural representation of the utility model embodiment, and wherein Fig. 1 is overall structure schematic diagram; Fig. 2, Fig. 3 are a point bronchial structure enlarged diagram; Fig. 4 is the structure enlarged diagram of nozzle.
In figure:
1 main tracheae, 1.1 main tracheae heads, 1.2 main tracheae afterbodys, 1A pore;
2.1 points of bronchuses, 2.2 adjacent next ones divide bronchus, and 2.1A, 2.2A divide bronchus pore;
3.1 nozzles, 3.2 adjacent next nozzles, 3.1A spout.
Detailed description of the invention
Fig. 1-Fig. 4 is the structural representation of the utility model embodiment, and wherein Fig. 1 is overall structure schematic diagram; Fig. 2, Fig. 3 are a point bronchial structure enlarged diagram; Fig. 4 is the structure enlarged diagram of nozzle.Show in figure, in this example, a kind of pulse pocket type dust catcher deashing injection tube, mainly comprises main tracheae 1, and main tracheae 1 arranges some points of bronchuses along airflow direction successively interval, divides bronchial end to arrange nozzle at every root.Show in Fig. 1, tracheae 2.1
,2.2 point bronchuses for being disposed adjacent along two of air-flow side, air-flow first arrives tracheae 2.1, and then arrives tracheae 2.2,3.1 and 3.2 and be respectively point bronchus 2.1
,nozzle on 2.2.
Show in Fig. 1, main tracheae has pore 1A, Fig. 2, Fig. 3 show, and point bronchus 2.1 has branch tracheal orifice 2.1A, and point bronchus 2.2 has branch tracheal orifice 2.2A, and Fig. 4 shows, and nozzle 3.1 has spout 3.1A.It is characterized in that, along airflow direction, (air-flow first arrives tracheae 2.1, and then arrive tracheae 2.2) a point bronchial caliber progressively diminishes, namely the diameter of pore 2.2A is less than the diameter of pore 2.1A, and nozzle vent 3.1A cross section on each point of bronchus is equal.In this programme, the caliber ratio of pore 2.1A and pore 2.2A controls between 1.005:1-1.02:1.In this example, 16 pieces points of bronchuses (in Fig. 1, a display part illustrates part point bronchus) are set along airflow direction successively interval.
In use, pulse jet air-flow is from head 1.1 rearwardly 1.2 flow process in main tracheae 1, and the dynamic pressure of air-flow reduces gradually, and static pressure increases gradually, and when blast pass arrives injection tube end, dynamic pressure all changes static pressure into.After have employed the technical scheme of dividing bronchial caliber progressively to diminish along airflow direction, the air flow rate penetrated from each nozzle and flow velocity equal, thus effectively improve the effect of winding-up dedusting.
