The novel denitration device for the power plant is reasonable in structural design and fully considers the site condition; atomized steam is mixed with dilute ammonia water solution, so that the ammonia water is atomized, the mixing effect of the dilute ammonia water solution and the flue gas can be improved, the denitration efficiency is increased, and denitration can be continuously and stably carried out synchronous with a boiler; the novel denitration device for the power plant is reasonable and reliable in technology, economical, practical and good in effect.
Description
Technical field
The utility model relates to the industrial equipment technical field, especially a kind of Novel electric station-service denitrification apparatus.
Background technology
Nitrogen oxide is one of primary pollution source caused atmosphere pollution.Usually said nitrogen oxide NOx has multiple multi-form: N2O, NO, NO2, N2O3, N2O4 and N2O5, wherein NO and NO2 are important atmosphere pollutions.The 70% direct burning that comes from coal in the discharge capacity of China's nitrogen oxide, power industry is again the coal-fired rich and influential family of China, so thermal power plant is one of main source of NOx discharge.Therefore, after being positioned at the newly-built, renovating and enlarging coal fired power generation unit in atmosphere pollution priority control zone and cogeneration units, in-service coal-fired unit and carrying out the low nitrogen burning technological transformation, its discharged nitrous oxides concentration still not up to standard or discontented Football Association amount is controlled requirement and all should be configured the denitrating flue gas facility.
The utility model content
The purpose of this utility model is to provide a kind of Novel electric station-service denitrification apparatus in order to overcome above-mentioned technical disadvantages.
The technical scheme that the utility model technical solution problem adopts is: a kind of Novel electric station-service denitrification apparatus, comprise burner hearth, described burner hearth inside is provided with burner, top is provided with the ammoniacal liquor shower nozzle, be provided with shower nozzle inner tube and shower nozzle outer tube on described ammoniacal liquor shower nozzle, described shower nozzle outer tube is connected with the dried compressed air pipe, be connected with atomizing steam pipe and mixing weighing device on described shower nozzle inner tube, the described mixing weighing device other end is connected with ammonia water tank and dilution water tank, be connected with the ammoniacal liquor delivery pump on described ammonia water tank, be connected with the dilution water delivery pump on described dilution water tank.
Be provided with the atomizing steam control valve on described atomizing steam pipe.
Be provided with the dried compressed air control valve on described dried compressed air pipe.
Described burner hearth bottom is provided with the stove seat.
The beneficial effect that the utility model has is:
The utility model reasonable in design, take into full account field condition, by atomizing steam, with the ammoniacal liquor dilute solution, mix, accomplish ammonia atomization, improve the mixed effect of ammoniacal liquor dilute solution and flue gas, improved denitration efficiency, and the denitration energy is continual and steady and boiler synchronous operation, technique is rationally reliable, economic and practical, is a kind of respond well denitrification apparatus.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be described below.
As shown in Figure 1, the utility model comprises burner hearth 9, described burner hearth 9 inside are provided with burner 10, top is provided with ammoniacal liquor shower nozzle 8, be provided with shower nozzle inner tube 6 and shower nozzle outer tube 7 on described ammoniacal liquor shower nozzle 8, described shower nozzle outer tube 7 is connected with dried compressed air pipe 13, be connected with atomizing steam pipe 14 and mixing weighing device 5 on described shower nozzle inner tube 6, described mixing weighing device 5 other ends are connected with ammonia water tank 2 and dilution water tank 3, be connected with ammoniacal liquor delivery pump 1 on described ammonia water tank 2, on described dilution water tank 3, be connected with dilution water delivery pump 4; Be provided with atomizing steam control valve 15 on described atomizing steam pipe 14; Be provided with dried compressed air control valve 12 on described dried compressed air pipe 13; Described burner hearth 9 bottoms are provided with stove seat 11.
Dilution water in dilution water tank 3 is delivered to mixing weighing device 5 by dilution water delivery pump 4 to be mixed with the ammoniacal liquor of ammoniacal liquor delivery pump 1 conveying, ammoniacal liquor after dilution is delivered to ammoniacal liquor shower nozzle 8 places, with the atomizing steam of atomizing steam pipe 14, mix, mixed ammonia atomization liquid sprays into burner hearth 9 tops through shower nozzle inner tube 6, mix with the flue gas of burner 10 discharges, realize denitrating flue gas.When ammoniacal liquor shower nozzle 8 does not have ammoniacal liquor to spray into, the cavity between shower nozzle outer tube 7 and shower nozzle inner tube 6 passes into dried compressed air, prevents spray nozzle clogging.
By pre-atomization outside the denitration reaction district, that utilizes the injection atomization does selective reaction containing ammonia gas and NOx, and denitration efficiency can reach more than 50%, has improved denitration effect.
The utility model reasonable in design, take into full account field condition, by atomizing steam, with the ammoniacal liquor dilute solution, mix, accomplish ammonia atomization, improve the mixed effect of ammoniacal liquor dilute solution and flue gas, improved denitration efficiency, and the denitration energy is continual and steady and boiler synchronous operation, technique is rationally reliable, economic and practical, is a kind of respond well denitrification apparatus.
