Abstract
The utility model discloses a selective non-catalytic reduction (SNCR) mixed metering and distributing device which comprises a machine body (9), wherein the machine body (9) is internally provided with an ammonia water flow control module, a dilution water flow control module and a compressed air regulating valve (6); the ammonia water flow control module and the dilution water flow control module are connected with a flow meter (5); and the flow meter (5) and the compressed air regulating valve (6) are connected with a plurality of injection units (7). According to the SNCR mixed metering and distributing device, the ammonia water flow control module, the dilution water flow control module and the compressed air regulating valve are effectively combined and arranged in the machine body, so that modularization can be achieved, and the injection concentration of a reducing agent can be flexibly, rapidly and conveniently adjusted according to the concentration of NOx and the escape amount of NH3; and therefore, the reduction efficiency is improved, the reducing agent is not wasted, and the reducing cost is lowered. Furthermore, due to the modularized design, the SNCR mixed metering and distributing device is simple to use, operate and maintain.
