Description
Technical field
The utility model relates to field of Environment Protection, especially relates to a kind of perforated trays spray column being applicable to sulfur dioxide treatment.
Background technology
Sulfur dioxide and nitrogen oxide affect larger gaseous contaminant in atmosphere pollution, has high risks to human body, environment and the ecosystem, along with the increasingly stringent of environmental requirement, and NO
xand SO
2the problem of discharge more and more receives publicity.Sulfur dioxide and nitrogen oxide mainly stem from the combustion process of the fossil fuel such as coal, oil, and the roasting of ore, the fume emission of smelting process, wherein various burning boiler particularly power plant boiler smoke evacuation there is the features such as concentration is low, exhaust gas volumn is large, floating dust is many and be difficult to administer.In conventional art, desulfurization and denitration are normally separately carried out by discharge sulfur dioxide in flue gas and purification of nitrogen oxides technology, which results in the defects such as the complexity of discharging flue gas purification system is huge, initial outlay is large, operating cost is high, seriously constrain the actual enforcement of discharge flue gas desulfurization and denitrification.Flue gas desulfurization technique is mainly based on Gypsum Wet, rotating spraying semidry method, in-furnace calcium spraying afterbody humidification activation, sea water desulfuration, electron-beam desulfurization, flue gas circulating fluidized bed desulfurization etc., wherein Wet Limestone method is the tail flue gas desulfur technology be most widely used in the world now, its subject matter is that the solubility of absorbent (lime or lime stone) is little, utilization rate is low, and waste residue amount is large; Gas denitrifying technology mainly contains SCR technology (SCR), SNCR technology (SNCR), electronic beam method, impulse electric corona method, complex compound absorption process and urea absorptive method etc., gas denitrifying technology mainly SCR technology, SNCR technology and SNCR/SCR combination technique comparatively ripe in current operation, but there is initial investment costly in SCR method, operating temperature range is narrow, and there is NH_3 leakage, can N be generated
2o, and the shortcoming such as catalyst easy in inactivation; And SNCR denitration efficiency is lower, and NH_3 leakage is many, causes secondary pollution.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of compact conformation, treatment effeciency much higher hole pallet spray column, and the technical scheme of employing is as follows:
Perforated trays spray column, comprise tower body, tower body sets gradually escape pipe from top to down, water smoke isolated gate, feed tube, shower, perforated trays, waste gas jet pipe, liquid storage bucket, drain pipe and residual cake valve, described waste gas jet pipe connects air inlet pipe, described perforated trays is inverted V-shaped, on have two-layer, upper strata perforated trays small opening is vertical holes, lower floor's perforated trays small opening is lateral aperture, described shower is multiple and horizontal plane uniformly dispersing, feed tube one end connects the shower other end and connects centrifugal water pump one end, flow sensor is provided with between centrifugal water pump and feed tube, the other end of centrifugal water pump and drain pipe UNICOM circulatory pool, the power set of centrifugal water pump are AC magnetoelectric machine, AC magnetoelectric machine connects wireless timing controller, wireless timing controller is electrically connected with flow sensor.
Further, described perforated trays connects tower body inwall by support.
Further, described wireless timing controller also connecting fluid crystal display.
Further, described water smoke isolated gate is circular arc.
Adopt above-mentioned perforated trays spray column, compact conformation, floor space is little, and perforated trays adopts double-deck setting, and exhaust treatment efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of perforated trays spray column.
Detailed description of the invention
Perforated trays spray column as shown in Figure 1, comprise tower body 1, tower body 1 sets gradually escape pipe 17 from top to down, the water smoke isolated gate 11 of circular arc, feed tube 10, shower 9, perforated trays, waste gas jet pipe 8, liquid storage bucket 12, drain pipe 14 and residual cake valve 13, described waste gas jet pipe 8 connects air inlet pipe 7, described perforated trays is inverted V-shaped, tower body 1 inwall is connected by support, on have two-layer, upper strata perforated trays 16 small opening is vertical holes, lower floor's perforated trays 15 small opening is lateral aperture, described shower 9 is multiple and horizontal plane uniformly dispersing, feed tube 10 one end connects shower 9 other end and connects centrifugal water pump 3 one end, flow sensor 6 is provided with between centrifugal water pump 3 and feed tube 10, the other end of centrifugal water pump 3 and drain pipe 14 UNICOM circulatory pool 2, the power set of centrifugal water pump 3 are AC magnetoelectric machine 5, AC magnetoelectric machine 5 connects wireless timing controller 4, wireless timing controller 4 is electrically connected with flow sensor 6, wireless timing controller 4 is connecting fluid crystal display (scheming not shown) also.
The above, be only detailed description of the invention of the present utility model, and those of ordinary skill in the art are in the scope that the utility model discloses, and the change that can expect easily, within the protection domain that all should be encompassed in utility model.
