Beneficial effect
The utility model is through being provided with the winding-up pipe, being used to spray the spray scavenging body of sweeping dust stratification regularly in flue, to feed in the flue bottom; Not only reduced the situation of dust deposit obstruct smoke pipeline widely; And order need not use hand sweeping, has saved maintenance cost largely.In addition, the utility model need not stop to treat the running of cleaner and electrostatic precipitator, thereby guarantee the effect of flue gas recovery when flue being carried out dust stratification spray and sweep, for high and stable yields create favorable conditions, improve the operating rate of equipment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the structural representation of pulsed electrostatic precipitator, the pulsed electrostatic precipitator comprises dedusting chamber 201 and flue 204, dedusting chamber 201 horizontal positioned, an end of its along continuous straight runs is an air inlet 202, the other end is an air outlet 203.Flue 204 is the L type; The horizontal segment 205 and elbow section 206 that comprise horizontal positioned; Wherein, horizontal segment 205 end of elbow section 206 dorsad is connected with the air inlet 202 in dedusting chamber 201, and elbow section 206 end of horizontal segment 205 dorsad is communicated with the fire door of treating cleaner.
Flue gas in the flue 204 feeds in the dedusting chamber 201 through air inlet 202, and air outlet 203 places are provided with axial id fan, and it utilizes principle of negative pressure that flue gas is sucked in the dedusting chamber 201.The direction of air-flow is the horizontal direction from air inlet 202 to air outlet 203.The direction that dust sinks is a vertical direction, vertical with airflow direction.The deposition of dust in flue 204 mainly occurs in its horizontal segment 205 places.
The utility model comprises the spray scavenging air pipe 207 that is arranged on flue 204 outsides.The bottom of the horizontal segment 205 of flue 204 has a plurality of through holes, and this through hole is along the bottom interval one determining deviation setting of horizontal segment 205.Be equipped with a winding-up pipe 208 with the inside and outside connection of flue 204 in each through hole, the outlet of winding-up pipe 208 is positioned at flue 204, and its inlet all is communicated with spray scavenging air pipe 207.
Feed spray scavenging body in the spray scavenging air pipe 207, spray scavenging body gets in the flue 204 through winding-up pipe 208.Because the outlet of winding-up pipe 208 is positioned at the bottom of horizontal segment 205; The winding-up of spray scavenging body can be kicked up the dust that is deposited on horizontal segment 205 bottoms once more, makes it along with the airflow direction in the flue 204, flue gases in flue 204 get in the dedusting chambeies 201 through air inlet 202.
Through the winding-up pipe 208 of the dust stratification of can jetting is set in the bottom of flue 204, can significantly reduce the phenomenon of dust deposit in flue 204, thereby make that the flue gas flow in the flue 204 is not interrupted, guarantee good dust removing effects.And; To flue 204 in, feeding spray scavenging body through winding-up pipe 208 does not influence the work of treating cleaner and electrostatic precipitator, therefore, sprays when sweeping carrying out dust stratification; Need not stop to treat the running of cleaner and electrostatic precipitator, thereby guarantee the effect that flue gas reclaims.
In the utility model, be positioned at flue 204 winding-up pipe 208 have a bending, its outlet is towards the direction of air inlet 202.This bending can be avoided when nothing spray scavenging body injects flue 204, and dust can pass through the outlet entering winding-up pipe 208 of winding-up pipe 204, even in the spray scavenging air pipe 207.
In the utility model, the outlet of winding-up pipe 208 and the distance of flue 204 bottoms are 50 millimeters, and it near the bottom of flue 204, can be swept the dust spray that is deposited on its bottom thoroughly more more.The outlet of winding-up pipe 208 can be processed as ellipse or oblateness, sweeps effect to strengthen spray.
The determining deviation setting at interval of the through hole of horizontal segment 205 bottoms, this spacing can be adjusted according to parameters such as dust deposit situation, flue gas flow and spray scavenging body flows.Though the deposition of dust mostly occurs at the horizontal segment 205 of flue 204, does not also get rid of the situation that this deposition can occur in elbow section 206.Therefore, the bottom of elbow section 206 also can be the same with horizontal segment 205, has a plurality of through holes, and this through hole is along the bottom interval one determining deviation setting of horizontal segment 205.Be equipped with a winding-up pipe 208 with the inside and outside connection of flue 204 in each through hole, the outlet of winding-up pipe 208 is positioned at flue 204, and its inlet all is communicated with spray scavenging air pipe 207.
It is 15 millimeters stainless steel tube that winding-up pipe 208 is selected diameter for use; Correspondingly; The through hole that is arranged on flue 204 bottoms also is 15 millimeters hole for diameter, and it can be fitted with the external diameter sealing of winding-up pipe 208, reveals through hole to prevent the flue gas in the flue 204.
Because mostly the flue gas in the flue 204 is flammable explosive gas, therefore nitrogen that adopt as spray scavenging body more.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model; The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection domain to be defined by appending claims and equivalent thereof.
