Assuming that the diameter of the ammonia distribution box (5) is D, when the desalted water flow meter (27) measures V=L×D 2 / 4, the desalted water electric valve (28) is controlled to close; The relationship between the percentage concentration C of the diluted ammonia water and the conductivity S of the ammonia water in the ammonia preparation box (5) is (aS3-bS 2 +cS) / 10 9 , where a, b, and c are constants; setting the conductivity S of the ammonia water in the ammonia preparation box (5) to obtain the required concentration C of the ammonia water; The concentrated ammonia water delivery pump (11) is controlled to start, and the amount of concentrated ammonia water used is counted and monitored by the concentrated ammonia water mass flow meter (10). The concentrated ammonia water is mixed with demineralized water through the distribution pipe (15) to prepare ammonia water of required concentration. When the conductivity S measured by the ammonia preparation intelligent conductivity sensor (16) reaches the ammonia water conductivity S set by the ammonia preparation box (5), the ammonia water concentration is adjusted. 设 When the concentrated ammonia solution delivery pump (11) is controlled to stop; When the concentrated ammonia water delivery pump (11) stops, the ammonia water prepared in the ammonia preparation box (5) reaches the conductivity S corresponding to the required concentration C. 设 After that, when the liquid level L measured by the third pressure-type liquid level sensor (20) is less than the set liquid level L 设 When the ammonia delivery pump (18) is controlled to start, the prepared ammonia solution in the ammonia delivery tank (5) is delivered to the dilute ammonia solution storage tank (6), and the liquid level measured by the third magnetic flap liquid level gauge (23) reaches the liquid level L 设 When the ammonia delivery pump (18) is controlled to stop, the ammonia mass flow meter (17) counts and monitors the delivery amount of the prepared ammonia water, and the intelligent conductivity sensor (21) monitors the conductivity S of the ammonia water in the dilute ammonia water storage tank (6); When the liquid level signal L measured by the second pressure type liquid level sensor (14) is less than L 低 When the desalted water electric valve (28) is controlled to start, the desalted water is input into the ammonia tank (5), and the liquid level measured by the second magnetic flap level gauge (13) reaches the liquid level L 设 When the conductivity of the ammonia water in the ammonia tank (5) is S<S 设 , then the concentrated ammonia water delivery pump (11) is controlled to start. When S=S 设 When the concentrated ammonia solution delivery pump (11) is controlled to stop.
