Description
Technical field
This utility model belongs to industrial smoke SO2Technical field of desulfurization, is specifically related to SO in a kind of employing hydrogen peroxide removing flue gas2Desulfurizing industrial fume system.
Background technology
In process of industrialization, energy resource consumption creates substantial amounts of SO2To atmospheric environment severe contamination, the formation of acid rain, the living environment to us that produces of haze cause irreversible infringement.Traditional desulfurization program is not only invested greatly, and energy consumption is high and by-product intractability the most easily forms secondary pollution.Existing hydrogen peroxide sulfur removal technology uses filler to take off tower and remains at great limitation, particularly remove SO at sulfuric acid tail gas and flue gases of cock oven2Method in also there is no particularly suitable technology.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of automaticity higher industrial waste gas desulphurization system for above-mentioned prior art.
The technical scheme in the invention for solving the above technical problem is: a kind of automatization apparatus for desulfurizing exhaust gas, including desulfuration spray tower, hydrogen peroxide storage tank, circulating slot, described circulating slot configuration clear water fluid infusion access tube, described hydrogen peroxide storage tank is connected to circulating slot to supplement hydrogen peroxide in circulating slot, described desulfuration spray tower tower body bottom is provided with air inlet, tower top is gas outlet, it is configured with the spraying layer of more than two-stage or two-stage between described air inlet and gas outlet, at described gas outlet and air inlet, is respectively arranged with SO2Survey meter, described circulating slot is configured with three or the circulating pump of more than three, arbitrary described spraying layer at least pipeline connects two described circulating pumps, circulating slot and the sulfuric acid waste produced that is connected bottom desulfuration spray tower in collecting desulfuration spray tower, the most external accident pool of described circulating slot and sulphuric acid storage tank.
Preferably, described hydrogen peroxide configuration of storage tanks cooling spray, described cooling spray is configured with clear water access tube.
Preferably, described hydrogen peroxide configuration of storage tanks has pressure transducer and temperature sensor.
The operation principle of this utility model apparatus for desulfurizing exhaust gas: by being respectively mounted SO between desulfuration spray tower air inlet and gas outlet2Survey meter, detect content and the content of sulfur dioxide in tail gas of untreated front SO 2 in waste gas, use the program in the programmable controller of presetting to calculate the concentration that the operation quantity of spraying layer, the input amount of circulating pump and hydrogen peroxide should be allocated, thus transfer whole desulphurization system and make the content of the sulfur dioxide in tail gas from the discharge of gas outlet, spray column top meet discharging standards.It addition, hydrogen peroxide storage tank can be monitored by pressure transducer and temperature sensor in native system in real time, open cooling spray according to Monitoring Data in good time.
Compared with prior art, the utility model has the advantage of: provide a kind of higher apparatus for desulfurizing exhaust gas of automaticity, it is automatically adjusted relevant desulfurization parameter according to sulfur content, the circulation fluid spray flux of the most each spraying layer, thus it is favorably improved desulfuration efficiency, make the sulfur content in tail gas meet regulated discharge standard.

As shown in Figure 1, automatization's apparatus for desulfurizing exhaust gas in the present embodiment, clear water fluid infusion access tube is configured including desulfuration spray tower 1, hydrogen peroxide storage tank 2, circulating slot 3, described circulating slot 2, described hydrogen peroxide storage tank 2 is connected to circulating slot 3 to supplement hydrogen peroxide in circulating slot 3, described desulfuration spray tower 1 tower body bottom is provided with air inlet 1.1, tower top is gas outlet 1.2, it is configured with the spraying layer 1.3 of two-stage between described air inlet 1.1 and gas outlet 1.2, at described gas outlet 1.2 and air inlet 1.1, is respectively arranged with SO2Survey meter (not shown), described circulating slot 3 is configured with three circulating pumps 4, arbitrary spraying layer 1.3 pipeline connects two circulating pumps 4, circulating slot 3 and the sulfuric acid waste produced that is connected bottom desulfuration spray tower in collecting desulfuration spray tower 1, the most external accident pool of circulating slot 35 and sulphuric acid storage tank.
As it can be seen, hydrogen peroxide configuration of storage tanks cooling spray, cooling spray is configured with clear water access tube.
Hydrogen peroxide storage tank 2 in the present embodiment is configured with pressure transducer and temperature sensor.
The higher apparatus for desulfurizing exhaust gas of automaticity of said structure, is automatically adjusted relevant desulfurization parameter according to sulfur content, the circulation fluid spray flux of the most each spraying layer, thus is favorably improved desulfuration efficiency, makes the sulfur content in tail gas meet regulated discharge standard.
In addition to the implementation, this utility model also includes the technical scheme that other embodiments, all employing equivalents or equivalence substitute mode are formed, within all should falling into this utility model scope of the claims.
