Abstract

The utility model discloses a flue gas denitration dust collector belongs to gas cleaning equipment technical field. Its technical scheme does: a flue gas denitration dust collector, includes consecutive imported flue, dust removal tank, pipeline, reaction tower, exhaust pass, the reaction tower still links to each other its characterized in that through ammonia pipeline and ammonia generating device: at least, incline to be provided with in the dust removal tank with divided layer filter about the dust removal tank, filter upper surface middle part sets up shock dynamo. The beneficial effects of the utility model are that: reasonable in design, simple structure, the vibrations through shock dynamo drive the vibrations board, and the vibrations contact on the vibrations board makes the shaking force become a little by the face, has improved the shockproofness to the smoke and dust breaks away from on making the filter, and is better in the effect of whole vibrations board than shaking force evenly distributed, thereby has reached the purpose of automatic clearance filter, has guaranteed the filter effect of filter to the smoke and dust.

Description

A kind of denitrating flue gas dust arrester
Technical field
The utility model relates to flue gas purifying equipment technical field, particularly a kind of denitrating flue gas dust arrester.
Background technology
The country of China's to be one with coal be main energy sources, major part coal is all utilize with combustion type, coal combustion discharge in waste gas containing a large amount of nitrogen oxide NOx, one of primary pollution source causing atmosphere pollution, if not treated, discharge beyond standards, can cause the problem of environmental pollution such as acid rain and photochemical fog.But denitrification process also exists following point: in flue gas, dustiness is large, catalyst poisoning in subsequent process is easily caused to lose efficacy, serious reduction denitration efficiency, adopts flue dust in the mode smoke treatment of filter plate in addition, then easily cause flue dust on filter pile up and affect filter effect.
Utility model content
For solving the deficiency of above-mentioned prior art, the purpose of this utility model is to provide a kind of denitrating flue gas dust arrester.
Invention thinking of the present utility model shows as: filtered the flue dust in flue gas by filter, and then shaking filter by vibration motor thus making flue dust depart from filter affects filter effect to avoid flue dust on filter to pile up.
A kind of denitrating flue gas dust arrester, comprise inlet flue duct, dedusting tank, reaction tower, ammonia gas generating device and exhaust pass, described inlet flue duct is connected with dedusting tank, dedusting tank is connected with reaction tower by conveyance conduit, described reaction tower is connected with ammonia gas generating device by ammonia conveyance conduit, described reaction tower lower end is provided with exhaust pass, is at least tiltedly installed with the layer filter separated up and down by described dedusting tank in described dedusting tank, and described filter upper surface middle part arranges vibration motor.
Described filter is arranged in described dedusting tank with the angle of 30 degree to 60 degree.
The described filter of some layers is set in described dedusting tank.
Described filter comprises filter screen, arranges jolting plate on the upside of described filter screen, and described vibration motor is arranged on described jolting plate upper surface middle part, and described jolting plate is that elastomeric material is made.
Described jolting plate lower surface is provided with the vibrations contact of some projections, and vibrations electric shock is against on filter screen, and the jarring forces of vibration motor is better acted on filter screen by vibrations contact.
Described dedusting tank upper inner is provided with the fan to canyon, and the flue dust that fan can contribute on filter departs from, and causes interference to promote to some extent the effect of denitration dust collecting in addition to the gas in dedusting tank.
Correspondingly below described filter be provided with the ash bucket that can extract out, in the middle of ash bucket, leave the opening by gas, lead to dedusting tank at inlet flue duct and to be become bottom longitudinal corner from level and also ash bucket is set, to receive the flue dust fallen from inlet flue duct.
By test, the beneficial effects of the utility model are, reasonable in design, structure is simple, drives jolting plate by the vibrations of vibration motor, and the vibrations contact on jolting plate makes shaking force become a little from face, improve shockproofness, thus flue dust on filter is departed from, the effect being evenly distributed on whole jolting plate than shaking force is good, thus reach the object of Automatic clearance filter, ensure that the filter effect of filter to flue dust.
