Abstract

The invention provides a sulfur trioxide spraying device, comprising a blowing device, a spraying pipe chamber, a wear-resistant protection board, a heat-preservation protection sleeve, nozzles, hexagonal platforms, short distribution pipes and blocking monitoring detectors. A windward side of the spraying device is provided with the wear-resistant protection board; the spraying pipe chamber is designed in a diameter-changing way in an axial direction; the short distribution pipes are arranged at two sides and end parts of the spraying pipe chamber and the nozzles are mounted on the short distribution pipes; the nozzles and the short distribution pipes are connected through threads; the nozzles are provided with the hexagonal platforms and the heat-preservation protection sleeve is arranged on the periphery of the spraying pipe chamber; the short distribution pipes are internally provided with the blocking monitoring detectors; and the blowing device is arranged at the inlet of the spraying pipe chamber. When the spraying device works, sulfur trioxide gas enters from the spraying pipe chamber and is uniformly sprayed out from the nozzles to be sufficiently mixed with smoke, thereby achieving the aim of reducing the electrical resistivity of dust. According to the invention, the sulfur trioxide gas is uniformly sprayed into the smoke to achieve the best mixing effect, the sulfur trioxide gas is prevented from being condensed before being sprayed into the smoke and the nozzles are prevented from being blocked, thereby realizing online real-time monitoring and automatic cleaning and blowing, reducing the maintenance workload and reducing the operation cost.

Description

The sulfur trioxide injection apparatus
Technical field
The present invention relates to a kind of flue gas conditioning device, be 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 objective of the invention is to,, a kind of sulfur trioxide injection apparatus is provided to the deficiency of prior art; 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 technical scheme that the present invention is adopted for its technical problem of solution 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 invention has the beneficial effects as follows: 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.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is a schematic cross-section of the present invention.
Among the figure: 1 is that blow device, 2 is that wear plate, 4 is that heat insulation sheath, 5 is that nozzle, 6 is that six side's platforms, 7 are the obstruction monitoring probe for distributing short tube, 8 for spraying tube chamber, 3.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details.
The present invention provides a kind of sulfur trioxide injection apparatus, comprising: blow device 1, spray tube chamber 2, wear plate 3, heat insulation sheath 4, nozzle 5, six side's platforms 6, distribute short tube 7, stop up monitoring probe 8.
Injection apparatus is provided with wear plate 3 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 2 and axially adopt the reducing design, consistent with the blast that keeps each nozzle 5 position with flow, thus be ejected into sulfur trioxide gas in the flue gas equably.
Injection tube chamber 2 both sides and end are provided with distributes short tube 7, distributes nozzle 5 is installed on the short tube 7, and nozzle 5 adopts with distribution short tube 7 and is threaded, and nozzle 5 is provided with six side's platforms 6, can use spanner easily to change nozzle 5.
Spray tube chamber 2 peripheries and be provided with heat insulation sheath 4, make sulfur trioxide before spraying into flue gas, keep higher temperature, avoid condensing.
Distribute short tube 7 inside to be provided with and stop up monitoring probe 8, monitor nozzle 5 in real time and whether stop up; Spray tube chamber 2 porch and be provided with blow device 1, stop up, just open the blow device 1 of porch, use compressed air that it is purged in case find nozzle 5.
During work, sulfur trioxide gas gets into from spraying tube chamber 2, from nozzle 5 ejections, mixes fully with flue gas equably, thereby reaches the purpose that reduces dust specific resistance.
