The utility model effectively prevents the ash blockage in the electrostatic precipitators, ensures the dust fall smoothness, and ensures the normal and effective operation of the electrostatic precipitators.
Description
Technical field
The utility model relates to a kind of grey accessory system that falls, especially a kind of electrostatic precipitator ash system that falls.
Background technology
Generally all be provided with vibrator on the ash storehouse, bottom of existing electrostatic precipitator, rapping at set intervals once shakes the ash in the grey storehouse fall and discharge through the vibrations of vibrator.The grey ash tube ash discharging hole from electrostatic precipitator that falls of electrostatic precipitator directly is discharged in the sluiceway; Because the electrostatic precipitator majority is in outdoor; Especially winter recirculated water behind ash, have certain temperature through furnace bottom inside, the outdoor rapid evaporation of flowing through, the steam that the evaporation back produces can get into grey storehouse along the ash tube ash discharging hole of electrostatic precipitator; Ash in the ash storehouse is met the water adhesion, and the meeting adhesion behind the certain hour in the grey storehouse becomes piece.The vibrations that this moment, the vibrator rapping produced also can't be shaken the ash after the adhesion fall, and cause the ash in the electrostatic precipitator ash storehouse to get rid of, and are cumulative, influence the operate as normal of electrostatic precipitator.
The utility model content
The purpose of the utility model is to have proposed a kind of electrostatic precipitator ash system that falls, and this ash system that falls can prevent effectively that the ash in the electrostatic precipitator from stopping up, and guarantees that ash is unobstructed, has guaranteed the normal effectively work of electrostatic precipitator.
The utility model is that the technical scheme below adopting realizes: a kind of electrostatic precipitator ash system that falls; Comprise compressed-air line, wherein, this grey accessory system that falls also comprises electronic strength execution valve and ball valve; The end that electronic strength is carried out valve is connected with pneumatic manifold or compressed air pump through compressed-air line; The corresponding other end is connected with ball valve through compressed-air line, the grey storehouse correspondence of each electrostatic precipitator be provided with a ball valve, be provided with at least one ball valve in the accessory system; The inlet of ball valve is carried out valve through compressed-air line and electronic strength and is connected, and the outlet of ball valve is communicated with the inner chamber in grey storehouse through compressed-air line.
In the utility model, described electronic strength is carried out valve and is connected with PLC.Go up the parameter of setting through PLC, control electronic strength and carry out the certain hour action of the every interval of valve once.
When the said ash system that falls comprises two or more ball valves, be connected in parallel through compressed-air line between each ball valve.
The beneficial effect of the utility model is: through this ash system that falls is set, can make the compressed air dust stratification in the grey storehouse that in time blows off, guarantee that ash is unobstructed, prevent that effectively the ash in the electrostatic precipitator from stopping up, electrostatic precipitator can normally effectively be worked; In addition; This system is provided with a ball valve to each grey storehouse; According to the unlatching size of the corresponding ball valve of different adjustment of ash amount in each grey storehouse, not only can guarantee the compressed air dust stratification in each grey storehouse that can blow off, but also use amount that can the save compressed air.
Description of drawings
Fig. 1 is the fall structural representation of ash system of electrostatic precipitator;
Fig. 2 is the fall syndeton sketch map of ash system of electrostatic precipitator when being provided with a plurality of grey storehouse.
Among the figure: 1 compressed-air line; 2 electronic strengths are carried out valve; 3 grey storehouses; 4 ball valves; 5 sluicewaies.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 and Fig. 2 are the described electrostatic precipitator of the utility model ash systems that falls.This ash system that falls comprises compressed-air line 1, electronic strength execution valve 2 and ball valve 4.The end that electronic strength is carried out valve 2 is connected with pneumatic manifold or compressed air pump through compressed-air line 1; The corresponding other end is connected with ball valve 4 through compressed-air line 1; Simultaneously electronic strength is carried out valve 2 and is connected with PLC; Go up the parameter of setting through PLC, control electronic strength and carry out valve 2 every interval certain hour actions once.As shown in Figure 2 because this electrostatic precipitator comprises three grey storehouses 3, so this ash system that falls also corresponding be provided with three ball valves 4, i.e. each grey storehouse 3 corresponding being provided with between 4, three ball valves 4 of a ball valve are connected in parallel through compressed-air line 1.The inlet of ball valve 4 is carried out valve 2 through compressed-air line 1 and electronic strength and is connected, and the outlet of ball valve 4 is connected with the inner chamber in grey storehouse 3 through compressed-air line 1.According to the unlatching size of the corresponding ball valves 4 of different adjustment of ash amount in each grey storehouse 3, thereby regulate compressed-air actuated flow, guarantee the compressed air dust stratification in each grey storehouse 3 that can blow off.
Utilize this ash system that falls realize blowing off course of work of dust stratification to be described below: at first, under the control of PLC setup parameter, electronic strength is carried out valve 2 and has been realized the discontinuity unlatching; Make compressed air discontinuity purge electrostatic precipitator ash storehouse 3; Simultaneously according to the unlatching size of the different adjustment ball valves 4 of ash amount in each grey storehouse 3, thereby regulate the flow of each grey storehouse compressed air, when the ash amount in a certain grey storehouse more for a long time; Increase the open amount of ball valve 4, thereby increase the flow of corresponding grey storehouse 3 compressed airs; When the ash amount in a certain grey storehouse relatively more after a little while, can correspondingly reduce the open amount of ball valve 4.Therefore, can guarantee that not only dust stratifications in each grey storehouse 3 can both be compressed air and blow off, but also use amount that can the save compressed air.Being compressed the dust stratification that air blows off falls in the sluiceway 5 along ash releasing tube.Make the ash that falls in the electrostatic precipitator unobstructed through this ash system that falls, prevented the generation of fouling phenomenon, guarantee normally effectively work of electrostatic precipitator.
