The which sulfur trioxide sprayer comprises a purging device, a spraying pipe cavity, a wear-resistant protection plate, a heat-insulation jacket, nozzles, hexagonal platforms, distribution short pipes and blockage monitoring probes, wherein the wear-resistant protection plate is arranged on the windward surface of the sprayer; the spraying pipe cavity adopts a diameter variable design in the axial direction; the distribution short pipes are arranged at two sides and end parts of the spraying pipe cavity; the nozzles are installed on the distribution short pipes; the nozzles are in threaded connection with the distribution short pipes; the hexagonal platforms are arranged on the nozzles; the heat-insulation jacket is arranged at the periphery of the spraying pipe cavity; the blockage monitoring probes are arranged inside the distribution short pipes; and the purging device is arranged at the inlet position of the spraying pipe cavity. When the sulfur trioxide sprayer works, sulfur trioxide gas enters from the spraying pipe cavity, is uniformly sprayed from the nozzles and is fully mixed with smoke gas, so that the purpose of reducing specific resistance of dust is achieved. According to the utility model, the sulfur trioxide gas is uniformly sprayed to the smoke gas to achieve optimal mixing effect, the coagulation of the sulfur trioxide gas is prevented before the sulfur trioxide gas is sprayed to the smoke gas, the nozzle blockage is prevented, on-line real-time monitoring as well as automatic blockage clearing and purging are realized, the maintenance workload is reduced, and the operating cost is lowered.
Description
Technical field
The utility model relates to a kind of flue gas conditioning device, is specifically related to a kind of sulfur trioxide injection apparatus.
Background technology
Electric cleaner adapts to the ratio resistance value of flying dust when collecting flying dust scope is 10
4Ω ㎝～5 * 10
10Ω ㎝ is when fly ash resistivity is higher than 5 * 10
10It during Ω ㎝ high resistivity dust; Charged and the discharge performance extreme difference of this type of dust, dust collection efficiency can obviously descend, and at this moment in flue gas, sprays a spot of sulfur trioxide gas; Combine with the moisture in the flue gas; Generate the sulfuric acid aerosol and be adsorbed on the dust surface, can reduce the ratio resistance of flying dust effectively, make it to be fit to electric cleaner and capture.At present; Using sulfur trioxide on the market is to spray the sulfur trioxide gas of heat in the flue before the deduster inlet as the flue gas conditioning technology of adjusting material; But employed injection apparatus is longer, and flue-gas temperature is far below sulfur trioxide temperature adiabatic condensation temperature, and sulfur trioxide is the inner and nozzle location dewfall at injection apparatus easily; Flying dust in the absorption flue gas, thereby plug nozzle.In injection apparatus, do not stop up monitoring and purging means yet; In running, do not know the operation conditions of injection apparatus; Can only unit is large and small repair during the inspection nozzle whether stop up, nozzle is fixed on the injection apparatus in addition, in case nozzle blocks or damages and need to change whole injection apparatus.
Summary of the invention
The purpose of the utility model is, to the deficiency of prior art, a kind of sulfur trioxide injection apparatus is provided; Can sulfur trioxide evenly spray in the flue and and flue gas fully mix; Prevent that sulfur trioxide gas from condensing in injection apparatus inside and nozzle location, can monitor the nozzle ejection state in real time and prevent that nozzle from being stopped up by flying dust, prevent the injection apparatus wearing and tearing; Reduce maintenance workload, reduce operating cost.
The utility model is the technical scheme that its technical problem of solution is adopted, and comprises blow device, injection tube chamber, wear plate, heat insulation sheath, nozzle, Liu Fangtai, distribution short tube, stops up monitoring probe.
Injection apparatus is provided with wear plate in the windward side, can carry out water conservancy diversion and prevent that effectively dust prolongs the service life of sulfur trioxide injection apparatus to the erosive wear of injection apparatus in the flue gas flue gas.
Spray tube chamber and axially adopt the reducing design, consistent with the blast that keeps each nozzle location with flow, thus be ejected into sulfur trioxide gas in the flue gas equably.
Spray tube chamber both sides and end the distribution short tube is set, distribute on the short tube nozzle is installed, nozzle adopts with the distribution short tube and is threaded, and nozzle is provided with Liu Fangtai, can use spanner easily to change nozzle.
Spraying the tube chamber outer periphery has heat insulation sheath, makes sulfur trioxide before spraying into flue gas, keep higher temperature, avoids condensing.
Distribute short tube inside to be provided with the obstruction monitoring probe, monitor nozzle in real time and whether stop up; Spray the tube chamber porch and be provided with blow device,, just open the blow device of porch, use compressed air that it is purged in case find spray nozzle clogging.
During work, sulfur trioxide gas gets into from spraying tube chamber, from the nozzle ejection, mixes fully with flue gas equably, thereby reaches the purpose that reduces dust specific resistance.
The beneficial effect of the utility model is: sulfur trioxide gas is injected to the mixed effect that reaches best in the flue gas equably; Prevent to condense before sulfur trioxide gas is in being injected to flue gas; Prevent spray nozzle clogging; Realized that sulfur trioxide injection apparatus on-line real time monitoring and automatic block clearing purge, reduced maintenance workload, reduced operating cost.
