Description

A kind of boiler waste gas treating device
Technical field
the utility model relates to boiler waste gas process field, particularly relates to a kind of boiler waste gas treating device.
Background technology
the flue gas that coal-fired steam boiler produces is the principal element causing China's bituminous coal type atmosphere pollution.Dust in flue gas is the main source of atmosphere pollution.In order to reduce the pollution of flue gas to air, many-sided comprehensive regulation must be carried out.On the one hand, adopt the combustion technology of high-efficiency low-pollution, improve the combustion process of fuel, control the generation of flue dust, fundamentally reduce flue gas to the pollution of air; On the other hand, adopt cost-effective flue gases purification, improve the performance of smoke eliminator, control the discharge of pollutant in flue gas.
at present, the mode for the gas cleaning of coal-burning boiler is also mainly single desulfurization or denitration or dedusting, and this obviously can not make flue gas purify thoroughly.And although the technology of desulphurization denitration on market has a lot, perfect not enough, also there are problems: 1, overall energy consumption is large, waste resource; 2, complex structure, cost are higher; 3, floor space is large, not easily installs; 4, spray liquid cannot recycle, the wasting of resources.Therefore, market is badly in need of high, the effective boiler waste gas treating device of a kind of purification efficiency.
Utility model content
the purpose of this utility model is to provide a kind of boiler waste gas treating device, inside arranges cyclone dust removal case, spray column, filtration tank, effectively can carry out dedusting, desulphurization and denitration process to the waste gas of boiler emission, purification efficiency is high, effective, makes finally discharged gas pure pollution-free.
the purpose of this utility model is achieved through the following technical solutions:
a kind of boiler waste gas treating device, comprise collection chamber, cyclone dust removal case, spray column, filtration tank, described collection chamber connects cyclone dust removal case by the first tube connector, described cyclone dust removal case connects spray column by the second tube connector, described spray column connects filtration tank by the 3rd tube connector, described filtration tank top device blast pipe; Described spray column inside is divided into spray chamber, lower spray chamber, and described upper spray chamber is connected by appendix with lower spray chamber; Spray equipment, dilute nitric acid solution pond on described upper spray chamber interior arrangement, described upper spray equipment is connected by left side tube connector with dilute nitric acid solution pond, device circulation denitration pump on described tube connector; Spray equipment, sodium carbonate liquor pond under described lower spray chamber interior arrangement, described lower spray equipment is connected by right side tube connector with sodium carbonate liquor pond, device circulation desulfurization pump on described tube connector.
described filtration tank inside device charcoal absorption filter mesh layer, HEPA high efficiency filter stratum reticulare, microporous ceramic filter plate, demister successively from the bottom to top.
device induced-draught fan on the 3rd described tube connector.
described a kind of boiler waste gas treating device, in running, first waste gas be collected in collection chamber, then dedusting in cyclone dust removal case is entered to by the first tube connector, enter after dedusting in spray column, first to enter under spray column in spray chamber, spray through sodium carbonate liquor, carry out desulfurization process, then enter in upper spray chamber by appendix, spray through dilute nitric acid solution, carry out denitration process, suck in filtration tank finally by air-introduced machine, through charcoal absorption filter mesh layer, HEPA high efficiency filter stratum reticulare, microporous ceramic filter plate filtering fine particles, after demister demist, be disposed in air, the gas of discharge is pure pollution-free.
the beneficial effects of the utility model: a kind of boiler waste gas treating device of the present utility model, inside arranges cyclone dust removal case, spray column, filtration tank, effectively can carry out dedusting, desulphurization and denitration process to the waste gas of boiler emission, purification efficiency is high, effective, makes finally discharged gas pure pollution-free.
