Description

A kind of boiler smoke processing method
Technical field
The invention belongs to coal-fired flue-gas process field, be specifically related to a kind of boiler smoke processing method.
Background technology
Rich coal resources in China is one of main energy source, but along with the use of coal, environmental problem highlights, and the burning of coal outwards discharges flue gas, containing a large amount of SOx, SO in flue gas 2, N 2the dusty gas such as O.According to statistics in atmosphere pollution SOx 90%, CO 71%, CO 285%, 70% and the flue dust of NOx 70% all from the direct burning of raw coal, therefore coal-fired flue-gas is the main cause forming China's atmosphere pollution.For improving Area Ambient Air Quality further, strengthening coal-fired steam boiler pollution control, being badly in need of finding a kind of flue gas desulfurization and denitration method efficiently.And in prior art, majority is all the desulfurization paying attention to flue gas, desulfurization can not be carried out out of stock simultaneously, and complex operation.
NO xcan cause photochemical reaction under the effect of sunlight, form photochemical fog, thus cause serious atmosphere pollution, therefore denitrating flue gas is same with desulfurization can not be ignored.Denitrating flue gas, refers to the NOx reduction having generated, thus removes the NOx in flue gas, can be divided into wet denitration and Dry denitration by Processing tecchnics.Mainly comprise: oxidative absorption method, SNCR method, absorption method, gas ions activation method etc.In oxidative absorption method, difficulty NO being converted to NOx is comparatively large, so the selection of this class methods oxidant and preparation are the cores of research.The more oxidant of current research has HClO 3, NaClO 2, O 3, H 2o 2and KMnO 4deng.Due to the nontoxic and non-secondary pollution of hydrogen peroxide, more to its research.But in prior art, utilize the technology of hydrogen peroxide treatment flue gas also to there is efficiency not high, the problems such as complicated operation.
Summary of the invention
For prior art Problems existing, the invention provides a kind of boiler smoke processing method efficiently, can simultaneous SO_2 and NO removal.
Technical scheme of the present invention is as follows:
A kind of boiler smoke processing method, comprise the following steps: open quartz burner switch, make quartz burner in running order, be that the flue gas of 50-70 DEG C passes through flue by temperature, the hydrogenperoxide steam generator simultaneously spraying into atomization respectively by hydrogen peroxide entrance, the solution A being passed into oxygen by oxygen intake, sprayed into atomization by solution A entrance, with flue gas hybrid reaction; Described solution A is made up of according to the volume ratio of 3:2 the potassium sulfate solution of concentration to be the ferrum sulfuricum oxydatum solutum of 5-10ppm and concentration be 5-10ppm.
The ultraviolet wavelength of described quartz burner is 310-360nm.
Described hydrogenperoxide steam generator concentration is 10-15ppm.
The purity of described oxygen is more than 99%, as: medical oxygen etc.Controlling the concentration of oxygen in flue is 0.1-0.3mol/L.
For a device for the above boiler smoke processing method, quartz burner is set in flue, on the tube wall of the flue near smoke inlet, hydrogen peroxide entrance, oxygen intake, solution A entrance are set respectively.
The quartz burner arranged in described flue arranges many at flue pipe wall diverse location as required, in flue, preferably arranges 4 quartz burners, lay respectively at the top of flue inner pipe wall, below, left, right.
During work, the flue gas of discharge is after flue gas cool-down device is cooled to 50-70 DEG C, in the irradiation of the quartz burner arranged in flue, hydrogenperoxide steam generator, solution A are sprayed in pipeline by atomizer and mixes with flue gas, pass into the concentration that appropriate oxygen regulates oxygen, the metal ion in solution A plays catalytic action simultaneously.Under the effect of Strong oxdiative, the NO in flue gas is converted into NOx, such as NO 2deng, and then again by NOx and H 2o reaction generates NO 3-; In addition, under the effect of Strong oxdiative, by SO 2be oxidized to sulfuric acid, its chemical equation is: H 2o 2+ SO 2=H 2sO 4.During recovery, add sodium hydroxide solution, NO 3-and SO 4 2-react with NaOH, generation sodium sulphate and sodium carbonate reclaim, and carry out desulfurization out of stock to flue gas simultaneously.
Beneficial effect of the present invention is:
1. boiler smoke processing method of the present invention, energy simultaneous SO_2 and NO removal, by adding oxygen and controlling applicable concentration, add metal ion and play catalytic action, substantially increase the out of stock efficiency of desulfurization, desulfurization degree more than 90%, denitration rate more than 95%, effectively reduces flue gas to the pollution of air;
2. boiler smoke processing method of the present invention, generates the product such as sodium sulphate and sodium carbonate after process, can recycle;
3. boiler smoke processing method of the present invention, operating procedure is not loaded down with trivial details, and cost is low, easily applies.
