With the most difficult requirement meeting new standard of particle concentration in newly-built coal-fired electric generation furnace discharge flue gas, it is necessary to it is suitable to select
Flue gas ash removal technology carry out dedusting.The original dedusting technology of thermal power plant mainly has electrostatic precipitation and bag-type dust, single cloth
Bag dedusting or electrostatic precipitation are difficult to power plant's flue fine particulates to go out, it is difficult to meet new " the thermal power plant's atmospheric pollution implemented
Thing discharge standard " (GB13223-2011), if setting up bag-type dust again or electrostatic precipitation have received investment and accounts at power plant's flue
The impact of the aspects such as ground area, the flue before cleaner unit sprays into certain density chemical reagent, and fine particle is become big
Granule, to facilitate cleaner unit dedusting, reaches discharging standards.Spray gun is one of core component of whole system.Described spray gun,
Simple in construction, respond well, low price, it is possible to meet dust removing effects.
Utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, just
In carrying, can disassemble, by ejection vaporization chemical reagent in nozzle, it is achieved in flue, fine particulates carries out bulky grain thing
Conversion, it is simple to the boiler flue spray gun of dedusting.
The technical solution of the utility model is: a kind of boiler flue spray gun, including gun inlets, spray gun mounting flange, spray
Mouth and lance pipe, described lance pipe is through flue and is fixed with flue by spray gun mounting flange, described lance tube
Road is at least two, and described lance pipe one end is provided with gun inlets, the other end is provided with nozzle, and described nozzle is by steaming
Sending out pipeline to be connected with lance pipe, described evaporation tubes is cross structure, and one end therein is connected with lance pipe, additionally
Three ends arrange nozzle.
Described nozzle interior flow passage ends is cone, and nozzle exterior opens one by runner central cross V-shaped groove, lance tube
Road is the stainless steel tube that external diameter is less than 32mm.
Described gun inlets is connected with sealed storage case by flexible pipe, and described sealed storage case is connected with pressue device, institute
Stating and be provided with control valve on flexible pipe, described control valve is connected with controller with pressue device, and the pressure being connected with controller passes
Sensor is arranged in sealed storage case.
The beneficial effects of the utility model are:
1. this utility model is the innovative design to flue dedusting, by ejection vaporization chemical reagent in nozzle, it is achieved
In flue, fine particulates carries out the conversion of bulky grain thing, overcomes the problem that power plant's fine particulates difficulty or ease remove so that electricity
In factory's flue, fine particulates is transformed into bulky grain, in order to have cleaner unit to remove.
2. the liquid chemical reagent in this utility model storage bin utilizes the temperature of expense cigarette to be vaporized in evaporation tubes
After, and it is injected directly into as a vapor in flue, the economization process of atomization compression.
3. this utility model evaporation tubes uses cross to arrange, arrangement of nozzles, on evaporation tubes top, uses sector spray
Mouth, spraying can cover whole flue cross section, and cross arrangement is simply little to whole flue resistance, it is simple to takes cigarette
Discharge.
4. this utility model is provided with multiple lance pipe, and assisted dust-collecting is effective, and is all existed by spray gun mounting flange
Carry out on flue sealing and fix, convenient disassembly.
5. this utility model is provided with pressure transducer, it is possible to the pressure condition in detection sealed storage case, and by adding
Pressure device carries out pressure regulation, it is ensured that effective ejection of chemical reagent.
6. this utility model control valve is connected with controller, it is possible to the spray volume of regulation chemical reagent, it is ensured that reach optimal
While agglomerating effect, save the usage amount of chemical reagent.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of boiler flue spray gun.
Detailed description of the invention:
Embodiment: see Fig. 1, in figure, 1-gun inlets, 2-spray gun mounting flange, 3-nozzle, 4-evaporation tubes, 5-sprays
