Description
Technical field
The present invention relates to boiler waste gas process field, more particularly to a kind of boiler waste gas treating device.
Background technology
The flue gas that coal-fired steam boiler is produced is the principal element for causing China's bituminous coal type atmospheric pollution.Dust in flue gas, is the main source of atmosphere pollution.In order to reduce pollution of the flue gas to air, it is necessary to carry out many comprehensive controls.On the one hand, the combustion process of fuel using the combustion technology of high-efficiency low-pollution, is improved, the generation of flue dust is controlled, pollution of the flue gas to air is fundamentally reduced；On the other hand, using cost-effective flue gases purification, the performance of smoke eliminator is improved, controls the discharge of pollutant in flue gas.
At present, for the mode of the gas cleaning of coal-burning boiler is also mainly single desulfurization or denitration or dedusting, this obviously can not be such that flue gas thoroughly purifies.And although the technology of the desulphurization denitration on market has a lot, but it is perfect not enough, also there are problems：1st, overall energy consumption is big, waste of resource；2nd, complex structure, cost are higher；3rd, floor space is big, not easy to install；4th, spray liquid cannot be recycled, the wasting of resources.Therefore, it is badly in need of the boiler waste gas treating device that a kind of purification efficiency is high, effect is good on market.
The content of the invention
It is an object of the invention to provide a kind of boiler waste gas treating device, it is internal that cyclone dust removal case, spray column, filtration tank are set, dedusting, desulphurization and denitration process can be carried out to the waste gas of boiler emission effectively, purification efficiency is high, effect is good, makes finally discharged gas pure pollution-free.
The purpose of the present invention is achieved through the following technical solutions：
A kind of boiler waste gas treating device, including collection chamber, cyclone dust removal case, spray column, filtration tank, described collection chamber connects cyclone dust removal case by the first connecting tube, described cyclone dust removal case connects spray column by the second connecting tube, described spray column connects filtration tank, described filtration tank top device exhaustor by the 3rd connecting tube；It is divided into spray chamber, lower spray chamber inside described spray column, 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 are connected by left side connecting tube with dilute nitric acid solution pond, device circulation denitration pump in described connecting tube；Spray equipment, sodium carbonate liquor pond under described lower spray chamber interior arrangement, described lower spray equipment are connected by right side connecting tube with sodium carbonate liquor pond, device circulation desulfurization pump in described connecting tube.
Device activated carbon adsorption filter mesh layer, HEPA high efficiency filter stratum reticulares, microporous ceramic filter plate, demister successively from the bottom to top inside described filtration tank.
Device induced-draught fan in the 3rd described connecting tube.
A kind of described boiler waste gas treating device, in running, waste gas is collected in gas collection room first, then dedusting in cyclone dust removal case is entered to by the first connecting tube, enter after dedusting in spray column, initially enter under spray column in spray chamber, Jing sodium carbonate liquors are sprayed, carry out desulfurization process, then entered in upper spray chamber by appendix, Jing dilute nitric acid solutions are sprayed, carry out denitration process, finally by air-introduced machine suction filter tower, through activated carbon adsorption filter mesh layer, HEPA high efficiency filter stratum reticulares, microporous ceramic filter plate filters fine particle, after demister demisting, it is emitted in air, the gas of discharge is pure pollution-free.
Beneficial effects of the present invention：A kind of boiler waste gas treating device of the present invention, it is internal that cyclone dust removal case, spray column, filtration tank are set, dedusting, desulphurization and denitration process can be carried out to the waste gas of boiler emission effectively, purification efficiency is high, effect is good, makes finally discharged gas pure pollution-free.
