Abstract
The utility model provides a waste gas dust removal system for a biomass boiler, which comprises a smoke outlet connected with a boiler system. After going out of the smoke outlet, waste gas is dedusted by a cyclone separator firstly and then enters a collecting chamber, a plurality of cloth bag type gas outlets are formed in the wall of the collecting chamber, the waste gas dust removal system further comprises a gas storage tank, and a plurality of electromagnetic valves are mounted on an outlet pipeline of the gas storage tank and are connected with the cloth bag type gas outlets, the waste gas enters a chimney to be discharged after going out of the cloth bag type gas outlets in the wall of the collecting chamber, and the electromagnetic valves can be selectively opened to be replaced. According to the utility model, the on-off of the gas is realized by opening and closing the electromagnetic valves to form impulse control; within a certain period, an impulse generator enables the dust intercepted at the cloth bag type outlets to fall into the collecting chamber at one time under high pressure; as a result, the dusting operation can be automatically finished, so that the difficulty during manual operation is eliminated, and meanwhile, the dusting efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of waste gas dedusting system of biomass boiler, belongs to boiler technology field.
Background technology
Boiler waste gas is processed perplexing always and is respectively used boiler unit, because containing a large amount of dust in boiler waste gas, as improper without any processing or processing method in boiler waste gas, can cause great pollution to atmosphere and surrounding environment, also waste energy simultaneously, now also there are some researchs of pair boiler waste gas treating device, though obtained certain achievement, but also exist some defects, for example, it is large that existing cleaner takies plot, operating cost is high, and exist complex structure, difficult in maintenance, parts are changed the defects such as loaded down with trivial details, or just emit after one-time dedusting, efficiency of dust collection is low, result of use is not very desirable, be further improved.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the utility model provides a kind of waste gas dedusting system of biomass boiler, and it is simple in structure, and efficiency of dust collection is high.
The technical solution of the utility model is: a kind of waste gas dedusting system of biomass boiler, comprise the exhaust opening being connected with steam generator system, first useless flue gas passes through cyclone separator dedusting from exhaust opening out, then enter a collecting chamber, collect on locular wall and be distributed with cloth-bag type gas outlet, also comprise an air accumulator, magnetic valve is housed on the outlet conduit of air accumulator and is connected with cloth-bag type gas outlet.Waste gas out enters afterwards chimney by the cloth-bag type gas outlet on collection locular wall and discharges.Wherein, a plurality of magnetic valves are optionally opened, and form and replace.
As a kind of preferred, on described collection locular wall, be evenly distributed with a plurality of cloth-bag types gas outlet.
As a kind of preferably, in described cloth-bag type gas outlet tetrafluoroethene cloth bag be shaped as triangle, increased filter area.
As a kind of, preferably in described collecting chamber housing sidewall, be provided with spray equipment, outside water pump is connected with described spray equipment.By spray equipment, dust and water-setting are got together, can reduce the airborne dust in collecting chamber.
As a kind of preferred, described collecting chamber bottom is provided with out ash bucket and weight flap valve, goes out the feed opening place of ash bucket described in described weight flap valve is connected in; Through the filtration of collecting chamber wall cloth bag, dust accumulation is in the bottom of collecting chamber, and when dust runs up to constant weight, weight flap valve is opened ash discharge automatically.
As a kind of preferred, described collecting chamber inwall is provided with separation net, is positioned at ash bucket top.Separation net plays the effect that stops screening, and the dust of Bag filter can fall by the grid of separation net and then be collected to out ash bucket.Once and collecting chamber part cloth bag accidental release, also can drop on separation net.
As a kind of preferred, on described collection locular wall, be provided with for checking the access door of separation net.The yet easily operation of process that can take out the cloth bag that comes off during maintenance, can significantly not affect construction speed.
The beneficial effects of the utility model are: the utility model system realizes the break-make of gas by the switch of magnetic valve, form pulse and control, and the dust that impulse generator once makes cloth-bag type exit intercept at certain cycle inner high voltage falls in collecting chamber.Therefore can automatically complete dedusting work, the difficulty while having exempted manual work, has improved the operating efficiency of dedusting simultaneously greatly.
The utility model system makes to discharge environmental protection, and boiler soot emission is by whirlwind+bag pulse dedusting system, without SO
2discharge, NOx, smoke discharge amount are lower than GB, and boiler emission reaches the country-level standard of environmental protection.
