Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
A kind of automation urea spray equipment for the processing of old circuit board cracking tail gas as shown in Figure 1, including prepare
Component 1 and the shower nozzle 3 for being arranged at exhaust steam passage, the dispensing assembly 1, which includes the dispensing assembly 1, includes urea dissolving tank
101st, vacuum feeder, upper water part, agitator 102, delivery pipe 103 and pump, the vacuum feeder and the upper water part according to
The proportioning of setting, supplies urea to the urea dissolving tank 101 respectively, and the agitator 102 stirs urea dirty solution so that Gu
Body urea granules dissolve；One end of the delivery pipe 103 and the discharge end UNICOM of the urea dissolving tank 101, the other end is through institute
Pump and the UNICOM of shower nozzle 3 are stated, under the drive of the pump, the delivery pipe 103 is by the urine in the urea dissolving tank 101
Plain solution is delivered to shower nozzle 3, is sprayed in the exhaust steam passage and is mixed with the waste gas under high temperature, is thermally decomposed urea therein
Go out ammonia, reduce the nitrogen oxides in tail gas.
Further, the dispensing assembly 1 also includes dilution pipeline 4, described to dilute by the setting of pipeline 4 and the shower nozzle 3
The urea liquid that side spray goes out steam with shower nozzle 3 sprays mixes, in concrete operations, when the dissolving of urea liquid needs certain
Between, the flow of shower nozzle 3 can be adjusted simultaneously by inputting steam or water in exhaust steam passage 2 in the process, it is molten to reach reduction urea
