Polymer produced by Shiheng Environmental ProtectionDenitrification equipmentWidely used in denitrification fields such as heavy kiln, light kiln, vertical kiln, rotary kiln, boilers, etc., this denitrification equipment has good denitrification effect and high denitrification and dust removal efficiency, and is widely recognized by users. Now let's share the principle and characteristics of the high polymer SNCR flue gas denitrification equipment for vertical kiln rotary kiln:
The polymer dry denitrification equipment developed by Shiheng Company has significant advantages: no clogging, smooth and accurate feeding, strong spraying force, and high flue gas coverage. It is a newly produced polymer denitrification equipment.Structure of polymer SNCR denitrification equipmentIncluding pneumatic vacuum feeding machine, silo, arch breaking and discharging device, spiral metering and conveying device, high-pressure fan, sprayer device, spray distributor, high-pressure powder spraying gun, conveying pipeline, frequency conversion control cabinet, etc.
Technical characteristics of polymer HNCR denitrification process:
1. High denitrification efficiency: As is well known, the denitrification efficiency of ammonia based SNCRs is generally between 40% -60% (except for fluidized beds); The denitrification efficiency of polymer HNCR can reach over 85%.
2. Simple process, easy to use, flexible spatial layout; The standardized airflow mixing and quantitative conveying integrated device is not limited by the site and space of the existing denitrification site.
3. Less one-time investment in the project: the integration, serialization, and standardization of the airflow mixing and conveying device eliminates the need for on-site construction and installation, greatly reducing the one-time investment compared to SCR technology.
4. Low energy consumption and low operating cost for denitrification; The power requirements for process equipment are minimal, and a power configuration of 5-22kW is generally sufficient for the entire process equipment (excluding gas source power). The dosage of polymer denitrification agent is the same or lower than that of ammonia based SNCR reducing agent. Generally, the cost of denitrification agent consumption is 30-50 yuan/ton of coal.
5. No harmful by-products, no secondary pollution formation; The reaction products of polymer denitrification agents are N2, CO2, and H2O, with no other organic compounds produced, no harmful by-products generated, no ammonium salts formed, and no ammonia escape phenomenon.
6. Has energy-saving and cleaning effects; After using polymer denitrification agents, the accumulation of ash and coking on the boiler tube wall will be alleviated, which accelerates heat conduction and reduces heat loss, thus achieving energy-saving and cleaning effects. Compared with the traditional SNCR denitrification process, the solid-state polymer denitrification process does not require the injection of process water into the furnace and does not consume latent heat of gasification, thus improving the combustion efficiency of the boiler.
