Abstract
The utility model relates to a device for treating ash fouling of an electrostatic dedusting ash delivery bin. The device for treating ash fouling of the electrostatic dedusting ash delivery bin comprises an installation casing pipe, a sprayer, a gas delivery pipe and a water filter, wherein the installation casing pipe is fixed on an ash hopper wall of the ash delivery bin; the sprayer is fixedly connected to the installation casing pipe; the gas delivery pipe is connected to the sprayer; and the water filter is installed on the gas delivery pipe. Compressed air without moisture is introduced into the ash delivery bin through the sprayer so as to form jet flow which plays a disturbance role on fouled ash generated at an ash discharge port. According to the utility model, through the disturbance effect of compressed air to flying ash, the problem that fouled ash is generated at the ash discharge port and blocks the ash discharge port is prevented; not only is that a dedusting system runs normally ensured, but also the constraint that the previous methods of manual knocking and the like are high in labor intensity and low in efficiency is got rid of; and the device for treating ash fouling of the electrostatic dedusting ash delivery bin has wide popularization and application value.
Description
Technical field
The utility model relates to electrostatic precipitator, particularly relates to the defeated ash silo in electrostatic precipitator.
Background technology
Electrostatic precipitation is that a kind of electrostatic field that utilizes makes gas ionization, dust particles is adsorbed onto the collecting method on electrode, in order to Purge gas or reclaim useful grit, and be used for factory, power station take coal as fuel in the industry such as metallurgical, chemical, collect coal ash and dust in flue gas.Dusty gas is during through the high-voltage electrostatic field, and air molecule is ionized and is cation and electronics, and electronics is combined with grit in marching on towards anodal process, makes the electronegative trend anode surface discharge of grit and deposits.
Flying dust in the defeated ash silo of electrostatic precipitator electric field is because thinner and temperature is low, and mobility is bad, often causes that lower ash is bad or simply not descend ash be clogging phenomenon.When this situation occurring, be generally to adopt the method such as beat manually to process, labour intensity is large and efficient is very low; If find or process untimely, also may cause electrostatic precipitator to jump car, cause the dust pelletizing system cisco unity malfunction, cause severe environmental pollution.
Summary of the invention
The purpose of this utility model is to provide a kind of device of processing the stifled ash of the defeated ash silo of electrostatic precipitation, the problem of stopping up to solve the defeated ash silo flying dust of electric field.
The device of the stifled ash of the defeated ash silo of processing electrostatic precipitation that the utility model provides comprises:
Mounting sleeve is fixedly mounted on defeated ash silo near on the grey headwall of dust inlet, is provided with adpting flange on mounting sleeve;
Nozzle is connected on mounting sleeve by the adpting flange that is fixed on its rear end, and described nozzle rear end is provided with air inlet, the front end sealing, and end face is provided with at least two nozzle bores, is covered with canvas in the nozzle face outside, and nozzle bore is covered;
Appendix is connected with the air inlet of nozzle, and water filter is installed on appendix.
Wherein, on every side ash headwall of defeated ash silo, mounting sleeve is installed all, described mounting sleeve departs from the axis of grey headwall to be installed, and all mounting sleeves depart to homonymy.
Described nozzle bore is 4, is positioned at the nozzle face surrounding.
The utility model is by injecting the compressed air after the water filter drainage in defeated ash silo through nozzle, and the jet that compressed air produces produces perturbation action to the flying dust that stops up, and has avoided producing dust stratification at dust inlet and has piled up, and the problem of stopping up dust inlet occurs.The utility model device is fine through the production run proving effect, thoroughly solved dust stratification blockage problem in the boiler electrostatic dust remover electric field, not only guaranteed the normal operation of dust pelletizing system, and broken away from the constraint of the large and method that efficient is very low of labour intensity such as in the past beaing manually, have and promote widely proper value.

The specific embodiment
A kind of device of processing the stifled ash of the defeated ash silo of electrostatic precipitation, its structure comprises water filter 1, appendix 4, nozzle 6 and mounting sleeve 5 as shown in Figure 1 and Figure 2.Near dust inlet 8 places, depart from grey headwall 3 axis and respectively have a hole on the ash headwall 3 of the four sides of defeated ash silo 2.Welded and installed sleeve pipe 5 on the hole is provided with adpting flange 12 on mounting sleeve 5.Nozzle 6 is placed in mounting sleeve 5, and the adpting flange 12 of its rear end is fixedly connected with adpting flange 12 on mounting sleeve 5.Appendix 4 is centered around defeated ash silo 2 surroundings, is connected with the air inlet 10 of nozzle 6 rear ends, is connected with a water filter 1 on appendix 4.
The structure of nozzle 6 as shown in Figure 3, Figure 4, nozzle od 20mm, internal diameter 16mm is provided with 4 nozzle bores 11 on the end face of nozzle 6, nozzle bore diameter 2～3mm.Be covered with canvas 9 in the outside of nozzle 6, to prevent the flying dust plug nozzle hole 11 in defeated ash silo 2.
During the work of the utility model device, 0.5 the compressed air of～0.6MPa is after water filter 1 degree of depth drainage, by being centered around the appendix 4 of defeated ash silo 2 surroundings, regularly the nozzle bore 11 on nozzle 6 sprays in defeated ash silo 2, the dust stratification thin to the interior granularity of defeated ash silo 2, that temperature is lower produces perturbation action, avoids producing the flying dust packing phenomenon at dust inlet 8.Flying dust after dredging is discharged defeated ash silos 2 through manual plate 7.
Claims (3)
1. process the stifled grey device of the defeated ash silo of electrostatic precipitation for one kind, described device comprises:
Mounting sleeve is fixedly mounted on defeated ash silo near on the grey headwall of dust inlet, is provided with adpting flange on mounting sleeve;
