The utility model relates to a high-pressure water mist selective non-catalytic reduction denitration device, which can be used for effectively solving the problems of large denitration investment, high cost and low efficiency. According to a technical scheme for solving the problems, the high-pressure water mist selective non-catalytic reduction denitration device comprises a high-pressure pump unit, an ejector and a storage tank, wherein a urea cabin is connected with a burdening pool through a metering cabin; the burdening pool is connected with the inlet of a urea solution storage tank through a burdening conveying pump; the outlet of the storage tank is connected with the high-pressure pump unit through a mixer; the high-pressure pump unit is connected with a multi-layer ejector in a hearth; and tap water pipes are connected to the burdening pool, the storage tank and the mixer. The high-pressure water mist selective non-catalytic reduction denitration device has the advantages of high denitration efficiency, simple device, large treatment air volume, low cost, cleanliness, avoidance of secondary pollution, convenience for running and maintaining, safe and stable equipment performance and long service life.
Description
Technical field
The utility model relates to gas processing device, particularly a kind of heavy pressure fine spray SNCR denitration treating apparatus.
Background technology
Along with rapid development of national economy, China has become production of energy and consumption big country.Consequent NOx discharge capacity also increases year by year, ranks first in the world at present, and in order to reduce the discharging of NOx, various countries have successively carried out big quantity research to coal-fired unit NOx control technology.Common gas denitrifying technology has SCR method, SNCR method, electron beam irradiation method etc., wherein SCR method and SNCR method comparative maturity.The wet flue gas denitration technology has desulfurization and denitrification integral technology, ozone oxidation absorption process and C1O2 oxidation absorption process etc.But use these traditional methods to handle that investment is big, operating cost is high, efficient is low.Provide a kind of denitrification apparatus simply efficient, with low cost, the technology cleaning imperative.
Summary of the invention
To above-mentioned situation, for overcoming existing technological deficiency, the purpose of the utility model just provides a kind of heavy pressure fine spray SNCR denitrification apparatus, can effectively solve big, high, the inefficient problem of cost of denitration investment of handling.
The technical scheme of the utility model is; Comprise high-pressure pump group, injector and holding vessel; The urea feed bin links to each other with dosing chamber through measuring chute, and dosing chamber links to each other with the import of urea liquid holding vessel through the batching delivery pump, and the holding vessel outlet is connected with the high-pressure pump group through blender; The high-pressure pump group is connected with the interior multilayer spray device of burner hearth, is connected to running water pipe on dosing chamber, holding vessel and the blender.
The utility model denitration efficiency is high, device is simple, handle large-minded, with low cost, clean cleaning does not exist secondary pollution, operation maintenance conveniently, equipment performance safety and stability, long service life.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
By shown in Figure 1; The utility model comprises high-pressure pump group, injector and holding vessel; Urea feed bin 1 links to each other with dosing chamber 3 through measuring chute 2, and dosing chamber 3 links to each other with 5 imports of urea liquid holding vessel through batching delivery pump 4, and holding vessel 5 outlets are connected with high-pressure pump group 7 through blender 6; High-pressure pump group 7 is connected with the interior multilayer spray device 8 of burner hearth, is connected to running water pipe 9 on dosing chamber 3, holding vessel 5 and the blender 6.
Described injector 8 is to be made up of 10-16 the nozzle of installing on a plurality of heavy pressure fine spray shower nozzles and each heavy pressure fine spray shower nozzle, and shower nozzle is spherical or many prismatics, the bore of each nozzle≤100 μ m (the mist particle diameter 10-100 μ m of general ejection).
The working condition of the utility model is that SCNR is combined denitration with heavy pressure fine spray.The absorption liquid that contains urea is sent in the injector by the high-pressure pump group, forms the heavy pressure fine spray ejection through shower nozzle, fully contacts, reacts with NOx, after purified gas reaches the discharge standard of regulation, discharges burner hearth.Because adopt urea as absorption liquid, temperature is controlled at 900 ℃ ~ 1150 ℃ in the burner hearth.
The NOx pollutant can be efficiently removed in efficiently denitration of the utility model, and denitration efficiency reaches as high as more than 90%, and denitration effect substantially exceeds the existing pollutant emission standard of country.Thorough reducing NOx harmful substance, and can reach perfect denitration effect, gas after treatment can reach innoxious discharging fully, never produces secondary pollution, plays the effect of high-effective disinfecting sterilization simultaneously.
The utility model investment is low, handles large-mindedly, and clean-up effect is stablized the denitration efficiency height; There is not secondary pollution, equipment performance safety and stability, long service life; Improve the surrounding area air quality, help the beautifying city appearance of the city, improve health level; The protection people's health is the innovation on the denitrification apparatus.
